DOW-UAP-D102, Project Blue Book File on Tremonton Film, Utah, 1952

This document records the Project Blue Book investigation and subsequent assessments of an incident near Tremonton, Utah, on July 2, 1952. Project Blue Book was a 1952-1969 U.S. Air Force program to investigate the nature and origin of unidentified flying objects (UFOs). The file describes the Air Forceโ€™s assessment of the principal witness, Delbert C. Newhouse, a U.S. Navy Warrant Officer specializing in photography, as honest and reliable, and as an expert with more than 1,000 hours of aerial-photography experience. Newhouse reported observing 12 to 14 reflective objects and recorded the event on color motion-picture film using a handheld Bell & Howell Auto Master camera. The file reflects an evolving Air Force assessment of the imagery over several years. Early documentation considered several possible explanations, including sunlight reflecting from birds or balloons, and a mirage effect, and did not identify the objects conclusively. Later assessments became more confident that the objects were seabirds reflecting sunlight, citing identifiable seabirds and similar films showing seabirds as bright points of light under comparable conditions. However, the filmโ€™s limited detail and lack of fixed reference points prevented reliable determination of the objectsโ€™ distance, size, altitude, or linear speed from the film alone. AARO Comment: The file contains conflicting references to the film format. Several documents describe a 35mm film, while contemporaneous submission documentation identifies the original as a 50-foot roll of processed 16mm Kodachrome color motion-picture film recorded with a handheld Bell & Howell Auto Master camera. Newhouse reported exposing approximately 30 feet of the roll during the incident and using the remaining film later that day to record unrelated mountain scenery in Idaho. Other records show that 35mm positive and negative duplicate blowups were produced from the original 16mm material. The file also indicates that the original film was duplicated for preservation, citing its deteriorating condition. The footage retained by the National Archives and Records Administration and presented in this collection as DOW-UAP-PR159 is a digitization of a 16mm print.

TO: Whom it may concern ATIAA-5/Lt Flues/ jos/65365/ 15 Dec 52 MEMORANDUM FOR RECORD PROBLEM: Tremont, Utah, sighting. FACTS AND DISCUSSION: On 15 Dee 52 It A. G. Flues telephoned It Malcom Ross, USN, at the Of- fice of Naval Research, University of Minnesota. The purpose was to deter- mine whether pillow balloon releases could account for the Tremont, Utah, incident of 2 Jul 52. It Ross had seen the Tremont/movies and it was his opinion, as well as that of Lt Lewis, UNg that the objects photographed were pillow balloons. However, Lt Ross said that the Navy had not released any pillow balloons in or near that area at that time. It Ross pointed out that General Mills, Inc., Minneapolis, is, in so far as he knows, the sole manufacturer of pillow bal- loons and suggested that ATIC contact Mr. Jโ€ข R. Smith of General Mills to determine what organizations and ageneles had purchased pillow balloons. It Ross also stated that in the winter of 1952, the "Crusade for Freedom" pur- chased many pillow balloons from General Mills. These were sent to various cities in the United States and released periodically. It Ross did not know the exact times, dates, or points of these releases, but he suggested that ATIC contact the "Crusade for Freedom". RECOMMENDATION: That ATIAA-5 contact Mr. J. R. Snith and the "Crusade for Freedon".

TO: Whom it May Concern SUBJECT: Tremonton, Utah, incident of 2 Jul 52 On 16 Dec 52 Lt A. G. Flues called Mr. J. R. Smith, Director, Balloon Re- search, General Mills, Inc., Minneapolis, Minnesota, to determine whether or not a pillow balloon release could have caused the Tremonton incident. Mr. Smith pointed out that in the winter of 1951, his company, the only known manufacturer of this type balloon, produced a large number of pillows for the "Crusade for Freedom". These balloons were distributed to both national and local offices of that organization and CMI was unable to say exactly what the organization did with them after receipt. However, GMI did say that they were released sporadically for publicity purposes from widely separated areas in the United States. In the "Crusade for Freedom" organization there have since been 100% personnel shifts, top to bottom and J. R. Smith was not too encouraging when It Flues suggested contacting the organization. However, he agreed to forward all shipping lists which will tell ATIC who the consignees were and just what numbers each received. Mr. Smith pointed out that in 1951 and until Nov 52, helium and hydrogen gasses were in short supply. The two companies which furnish these gasses are Air Reduction Company and The Linde Companyโ€ข Mr. Smith suggested contacting their distributors in the area of the sighting. Recommendations: That ATIC follow-up with the lists Mr. Smith will provide and that ATIC check distributors of hydrogen and helium in the Utah area.

Travel Report - Minneapolis, Minnesota 29, 30, 31 December 1952 On 29 Dec 52, It A. G. Flues went to Minneapolis, Minnesota, to contact the Field Representative of ONR and the General Mills Corporation there. The purpose was to determine if the UFO's in the Tremonton, Utah, movies of 2 July 52 might be pillow balloons. On 30 Dee the films were run off in the balloon room of the Physies Building, University of Minnesota. The following were in attendance: Lt Malcolm Ross, USN S2C Leroy Harger, USN Dr. Nye, U. of Minn, Balloon flights and geophysics Dr. Winkler, U. of Minn. Balloon flights and geophysics Frank C. Jewett, Exec. Vice-President, Research Dept., General Mills, Inc. J. R. Smith, Chief, Meteorology Dept., General Mills, Inc. There were various others present all of whom have had experience in flying pillow balloons. The films were run off eight times, at various speeds, and were frequently stopped at good frames. All were informed of the background data. It was the consensus of opinion that the objects resembled pillow balloons in flight very closely and did nothing that pillows would not do in similar circunstances. J. R. Smith was the least convinced of this hypothesis; however, he felt that the objects were a bit too bright and maneuvered a bit too fast. The head meteorologist of GMI pointed out that winde to 8,000 ft. at H111 AFB would probably be different from those at Tremonton because of topography and land-sea effect. The extreme stability of the atmosphere on that day would, he added, make ascent very slow and would tend to stabilize a pillow at a given altitude. Additionally, wind direction is capable of a 180ยฐ shift within perhaps LASSIFIED Authority NND 923007

โ” PAGE 29 โ”

500 ft. of altitude which could account for a high or low balloon, with relation to the group, to proceed in an apparently opposite direction. If the objects are pillows, the consensus was that they are not over 6,000 ' altitude, probably mich less. If this is so, they cannot possibly have been aloft for more than 12 hours, and this only if filled with warm air or underinflated with gas or ballasted for a given altitude. There is a much greater probability that they are ascending and have been released from a nearly point not over 1/2 hour before. None of the persons present placed much faith in the computations of angular velocity, since all were predicated upon Newhouse's holding the camera still. It Flues went over to GMI later on and obtained fron J. R. Smith the names and addresses of consignees who received pillow balloons during the period Sep 51 - 2 Jul 52. Also Lt Flues picked up some photos of pillow balloons and the flight tracks of three Navy Skyhooks released in Sept 52 from Tillamook, Ore. Gen- eral Mills had no movies of pillows which approximated the Tremonton films as GMI's footage seemed to be shot against cloud background and when the balloons were lower. However, they will be launching pillows from Wendover, Utah, in Feb 53 and will make movies then. The course of action recommended was for ATIC to check all persons in the western U.S. who received pillows. There were some other shipments to GMI home and farm appliance stores, and J. R. Smith agreed to send ATIC the names and addresses of such consignees. List of consignees: 2 DECLASSIFIED Authority NND 923007

11 F1 6 53 UNCLASSIFIED Memorandum for Record 1. During a trip to Washington, D. Co, on 29 Jan 53 Capt Ruppelt was informed that the press had learned about the Tremonton, Utah, movies and that Mr. Al Chop of the Office of Public Information, Department of Defense, Col Teaberg of AFOIN-2, and others believe that the movies should be re- leased in accordance with the promise made this summer to the press that no information on the subject of Unidentified Flying Objects would be withheld. Capt Ruppelt agreed with this point and it was decided that the factual data on the incident would be sent to Capt Harry B. Smith, AFOIN-2A2, who would pass it on to Mr. Chop who in turn would write the release. The telecon also requested that the release beforwarded to ATIC for coordination. The subject telecon is TT15, 5 Feb 53, Item 2. 2. On 9 Feb 53 Mr. Chop called that he written the release and showed it to Col Smith of AFOIN-2A. They believe that there would be a question asked as to the findings of the Air Force and Navy photo labs and that these reports would have to be released. If they weren't released, the press would begin to think they contained some "hot" material and that the Air Force was holding back some important data. ATIC concurred that this could happen., and that if it did happen it could create a great deal of excitement. 3. The Air Force lab analysis concludes that: a. They are reasonably certain that the brightness of the images on the film exceeds that of any bird. DOWNGRADED AT & CHAR INTERVALB: DECLASSIFIED AFTER 12 YEARS b. The objects, are not spherical balleons. DOD DIR 5200.10 C. The objects could be aircraft. (Note: the absence of sound ( 10" almost rules out aircraft. Aircraft in a "dogfight" can be heard at almost any altitude. In addition, the area of the sighting was not a restricted air space area and it is doubtful that such flying would be carried on in the airways.) UNCLASSIFIED DECLASSIFIED Authoritv NND 923007

โ” PAGE 38 โ”

UNCLASSIFIED c. Have two aircraft do maneuvers at various altitudes and photo- graph them. d. Request that the Navy re-do the study using the methods of density measurement that are prescribed by the astronomers. Conclusion 6. If it is deemed advisable to release the movies quickly, state that the Air Force cannot positively identify the objects but they are reasonably sure that they are balloons or gulls consequently no further effort is going to be put into the incident. If the Navy and Air Force reports are requested, state that due to the meager data they used, the reports must be discounted. It would be rather poor policy to state that the Navy had made an error in the beginning of their analysis. 7. If it is too much of a risk to do this (suggestion in paragraph 6) immediately go ahead with items a, b, and c of paragraph 5 on a high priority basis. Recommendations 8.. It is recommended that the above plan be given to AFOIN-2A2 and let them confer with the Director of Intelligence on the subject of a release.

UNCLASSIFIED The Navy report says the objects are: a. Self-luminous or light sources b. Could not be aircraft or balloons C. No bird is known is reflect enough light to cause the images shown on the film. It can be noted that the Navy people deduced this from their analysis of the brightness of the image on each frame. This required about a 1,000 manhours. It was brought out by two astronomers who heard a Navy briefing on the analysis of the movies that the method used to measure the brightness of each spot was wrong, therefore, the results of the entire study were wrong. 4. The subject of the release was discussed with It Col Johnston and Col McDuffy and it was decided that the movies would be released without com- ment as to what they were and hope that no questions were asked about the Navy report. This is a "calculated" risk of another big "flap". 5. The other alternative is to quickly get more data on the subject. Several things can be done and are listed below in the order of how soon they could be accomplished: DOWNGRADED AT & YEAR INTERVALE; DECLASSIFIED AFTER 12 YEARS.- DOD DIR 5200.10 = a. As far as gulls are concerned the big question is, how much light will be reflected? Can you see a gull reflecting light and not recog- nize that it is a gull? To check this it would be necessary to go to a loca- tion where you have a lot of gulls and bright sunlight and take movies with a 3-inch lens. It would be necessary to know how far the gulls were away each time a movie was taken. At this time of the year Florida is the only place where sunshine and gulls can be assured. b. Using special funds, have General Mills release a group of pillow balloons arranged in the same sequence as the objects are in the movies and measuring the distance at which the movies were taken.

This color film provides an instance of a sighting being substantiated by motion pictures and confirms the faith of the USAF in the veracity of the many citizens who have reported sightings of unidentified objects or phenomena in the air.? The film was forwarded to the USAF by Warrent Officer Delbert C. Newhouse, Aviation Supply Depot, Naval Supply Center, Oakland, California.3 Warrent Officer Newhouse stated that the film was exposed 7 miles North of Tremonton, Utah, on the U.S. Highway 30 at 11:00 a.m. MST, 2 July 52: and that he was using a Bell and Howell Auto Master (hand-held) with a three inch telephoto lens at F/8 for the first few feet of the film and the balance at F/16 all at sixteen frames per second. 4. Examination of the film to date allows a deduction that the images were caused by surfaces having good reflective qualities, such as seagulls oR balloons], or by bodies or substances possessing high intensity light sources. Images appearing on the film are nonsufficiently defined to permit identification or determination of form or substance and should have been caused by unknown objects or undetermined known objects. The absence of any reference points, even clouds, in the background has made it impossible to estimate the distance of the objects from the camera, thus precluding a determination of size and linear speed.

It is requested that any evailable information be furnished to the Air Technical Intelligence Center as to the disposition of this film after the interpretation was completed. 4. Information is further requested as to whether or not any copies of this film are on hand there. FOR THE COMMANDER BARBARA 1. CUNNERS 1st Lt. USAF Assistant Adjutant.

COPY UNCLASSIFIED 21 Nay 1956 MEMORANDUM PORt The Scientifia Advisor SUBJSCT: Report on Preview of Motion Ploture "Unidentified Flying Objects" Through the personal assistance of Col. Cross, Chief, Office of Information Services, AMC, an advance copy of the film *Unidentified Flying Objects" was previeved by pertinent menbers of ATIC on Friday, 18 May 1956, in Bidg 167, Area B, Wright Patterson Air Porce Base. 2. The following represent the general corments and opinions with regard to the film previeved: The f1lm, purporting, to be factual and documentary, apeara to over dramatize each case al ghting. b. The film atrives, through Ita showing, to mintain the impression that an unknown menace or super-intelligent being, alien to this vorld, la constantly in the background. 6. The case sightings and the individuals piotrayed (the acting was Tery amateurish for a Hollywood production) was factual to a certain extent. However, the conclusions, mecifio or implied, are those of the producer's and not those of the Air force, d. In each instance of the portrayal of a case, the film dramatically, and with great suspense, presenta the incident and eircumstances surround 1n8 the aighting, then abruptly drope the matter in a "lady or the tiger" technique.

UNCLASSIFIED De (1) We do not agree with the fila's concluaion *not aireraft. not balloons, not-Birds.* A comparative analyses was mada of a copy from the original film strip, and that shown by Green-Rouse by Major Willner and Major Buckmaster, ATIC photo specialista. The original film shows the presence of sea gulle on a number of frenes. This is not shown in the Hollywood version. (2) Further, It is not necessary to state that a particular species of see gull are prominent in certain parts of Utah. It should be pointed out that the Utah species fa almost pure-white in color, in contrast to ita anoky or grey-mrked ses-coast cousin. (3) In the opinion of ATIC photo specialists, any under exposure of these sea gulla againat a high-lighted aly would tend to "wash out" details of the body and wing out- line of the gulle, giving them a vite circular appearance at a distance. (Officer Newhouse openly admitted in the f1lm that he under exposed his "abota".) (4) This la confired by the original analyeis in our files, made in early 1953 by the Photo Reconnaiasence Laboratory, WADC. These reporte were not shown to Majors willner and Buckmater for review until after their analyses (1tems 2, 8, and 3 above) were completed. Mento?1 Case: Conclusions of the Air Firce are that Capt. โ€ข Mantell was apparently trying to Intercept a fast riding Sky Hook" balloon. The "Sky Hook* project was known only to few people at that time. Unlike weather balloons "Sky Hookยป balloons were huge (100 feet in diameter). coinciding with Capt.

COPL UNCLASSIFIED other then that both appeared to be wingless and somewhat @ lindrical. This case is classed as an "unknown" by virtue of the high credibility given to observer's of this type. f. Washington Inder Sighting: (1) In the Department of Defense "Minutes of Presa Conference Held by Ma jor General John A. Somford", 29 July 1952, @py In file at both ATIC and PIO, it was explained to the press that these aightings (peges 5 through 17) mey have been the result of a combination of factors: temperature inversions, moisture lapses, and atnospherie conditione which bend radar rays 1D such a manner that norially undetected ground targete become visible on the redar screen, in a random manner from one antenna rear to the next, thus allowing some misinterpretation that these stationary targets were moving. It should be emphasized that ae photos or motion pictures were ever made of the radar screen, as shown in the motion picture. (3) The attempt to represent the blips as possible interplanetary space ships, gleefully playing "tag" with our jet afrcraft over Washington, undoubtedly will produce the desired dramatic mood and auspense. However, the incident over the radar scope was unscientific, not supported by fact, nor the conclusions of the Air Force.

QUESTIONS REGARDING ANALYSIS OF FILM 1. Are images made by light source or reflection? 2. Any indication of what kind of objects could have caused images? Is there any bird sufficiently actinic to cause images? Could they have been caused by aircraft or balloons? 3. What causes the impression that some objects at times appear to becone 2 or 3 objects, at times appear to merge into one? 4. Do all objects have sane characteristics? a. Same apparent shape? b. Same relative size? c. Same Color? d. Same general motion? 5. What are shape(s), color(s), and relative size(s) of objects? 6. To what can the "fade-in" and "fade-out" of the objects be attri- buted? 7โ€ข What type motion is attributable to the objects (about their own axis as well as about the axis of flight path)? 8. Is there any acceleration evident in their motion along flight path axis? 9. Can the motion of the camera (panning and joggling) be allowed for sufficiently to permit determination of the angular velocity of objects which cross the field of view? (Reference particularly the single object which crosses field; photographer states that camera was held motionless while ob- ject crossed field of view.) 10. Determine patterns of flight from position plots for each frame, then: a. Is there any recurring pattern in the relative position of the objects? b. Do they maintain same relative positions in formation during any maneuvers, particularly violent maneuvers? c. Is relative position maintained coincidental with movement about their axes? d. If undulating motion is present among a number of objects which are maintaining a semblance of formation, do those objects undulate in phase? Ditto for tumbling motion. Is there any indication of abrupt changes in direction of flight path through fairly large angles (egโ€ข, 90ยบ or more during interval of 2 or 3 frames)? DECLASSIFIED Authority NND 923007

STATEMENT BY SOURCE Place:- Time:- Camera:- 305 About 7 miles north of Tremonton, Utah, on U.S. Highway No. 305. 1110, Wednesday, 2 July 1952. B&H Automaster, magazine load, 3" telephoto lens, 16 frames per second. Handheld. Exposure:- First few feet - f:8. Balance - f:16. Clear sun, cloudless sky. EKCO Kodachrome film - Daylight. Exposure was changed with the mistaken idea of darkening the sky to gain greater contrast. The result was merely general underexposure. Background: - Driving from Washington, D.C., to Portland, Oregon, on the morning of 2 July, my wife noticed a group of objects in the sky that she could not iden- tify. She asked me to stop the car and look. There was a group of about ten or twelve objects that bore no relation to anything I had seen before, milling about in a rough formation and proceeding in a westerly direction. I opened the luggage compartment of the car and got my camera out of a suitcase. Load- ing it hurriedly, I exposed approximately thirty feet of film. There was no reference point in the sky and it was impossible for me to nake any estimate of speed, size, altitude or distance. versed course and proceeded away from the main group. I held the camera still ay mom the main group c Toward the end one of the objects re- and allowed this single one to cross the field of view, picking it up again and repeating for 3 or 4 such passes. By this time all of the objects had disappeared. I expended the balance of the film late that afternoon on a mountain somewhere in Idaho. DECLASSIFIED Authoritv NND 923007

Tests and Procedure. a. Plots. The film exposed in Utah is in very poor condition; dry, brittle, and with a tendency to break. After initial viewing, duplication of the film was performed in order to preserve the film. In the duplication process some color correction was made to permit better viewing of the objects. To prepare plots of the objects, a stop frame projector was rigidly mounted at a fixed distance from a finely-ground glass screen. The magnification was 22 times giving a format size of 14.2" wide. This proved very satisfactory and provided a shadow free image upon which overlay plots could be made. DOWNGRADED AT & YBAR INTERVALS; DECLASSIFIED AFTER 12 YEARS.

Code 01/Hww/abh 112 Serial: UNCLASSIFIED 0105 MAY 4 1953 Subj: Interpretation of Movies of Unidentified Objects; progress report on A preliminary detailed study of the Utah film was made and it was decided that: a. Brightly colored spots of red and green lasting only one or two frames were not to be considered. b. Water spots could be detected easily and eliminated from the study. c. The color of the objects was fairly constant as blue-white. d. Size and luminosity of an object varied through-out the film. For convenience in interpretation, the film was divided into three parts, each part being considered an entity. Part I consisted of the footage taken at f8; Part II, the footage taken at f16 with a panning motion; and Part III, the footage taken at f16 during which the camera was held steady. Three definite groups of lights were observed through- out the film and plots were recorded as follows: TABLE I PLOTS OF POSITIONS Utah Parts I II III Control Holding to lower group Chart Not enclosed I II I Holding to one object and azimuth of another Arbitrary 1/2 inch correction per frame for panning 2 and 3 4 III Holding to frame outline 5a and 5b I Montana UNCLASSIFIED One image held to base 6 line.

Densitonetric tests: Densitometric data were obtained with a Densichron, Model 2150 manufactured by the Welch Scientific Company. The Densichron has a scale range of 0-3. The procedure was to project each frame at approximately 22 times magnification onto a finely-grained-glass screen. The back- ground (siy) was then measured at several places and the density set to 3.0 (variations in background densities were in the order of 0.02 and were regarded as uniform). A set of three readings were made of each of seven objects in Part I, and of the single object in Part III of the Utah Film. Readings were made of the entire Montana film. Enclosure (8a and 8b) are graphs of the density readings obtained of the two lower groups of objects in frames 1-129 of the Utah film. Enclosure (9) is a density graph of the single object (94 frames) in Part III. Enclosure (10) is a graph where six successive Densichron readings were averaged and advanced one reading each deter- minant. Of the Montana film, densities were plotted as above and are enclosures (11) and (12). The results of the density readings may be questioned in that these objects varied in size so that at the minimum sizes the densichron probe was measuring the entire object, and at the maximum size the probe was measuring only a portion of the objects. Because of this situation only the largest readings obtained b scanning the objects were used. It is understood that normal procedure would be to read the entire object. This was impossible with the equipment on hand. In addition the film, with which this investigation was conducted, is a duplicate of a copy. This raises the question as to whether the central portion of the objects were burnt out during the duplication processing. Density readings were made to compare the clear areas and the objects. It was found that the minimum difference is 0.4. This indicates that relative luminosity may still be obtained with the pro- cedure used. Concurrent with the density readings, relative sizes of the objects were noted in order to correlate distance and luminosity. Enclosure (13) is a plot of the same object wherein the relationship of distance and luminosity can be detected in ULรœWNGRADED AT & YRAR INVAR; 3. Answers to Questions. DECLASSIFIED AFTER 12 YEARS.

Analysis of the graph correlating luminosity and size indicate that as the luminosity of the objects increase, the size is larger also. This could be the effect of viewing directly, a reflecting surface. This is considered not probable because of the length of time they were viewed continuously on the film, approxi- mately 90 seconds, and because of the angle through which they were photographed, approximately 60 degrees. It is felt that if these images are reflective surfaces, blinking would occur during a period of 90 seconds while passing through an angle of 60 degrees when photographed at the rate of 16 frames per second. This premise would permit highly reflective balloons or spheroids to be a possibility. However, the velocity and acceleration computations (sub paragraph o) rule this possibility out. It appears, therefore, that if these objects are a reflecting surface, they are of a design, speed, and power not commonly known. The velocity and acceleration attributed to the objects may be caused by light reflected off a highly reflective surface onto an atmospheric screen where a slight angular turn of the reflective surface would appear as high acceleration. This possibility is considered not probable because of the sun angle and atmospheric condition reported at the time of photography and because of the variations in luminosity which, under the above conditions would remain constant. It is the majority opinion of the group conducting this analysis that these images are light sources. This will explain the non-blinking and variations in luminosity - but not the velocity or acceleration factors. In either case, light source or reflective surface, it appears as if the objects are of a nature which we are not able to identify in terms of natural phenomena or commonly known man-made objects. 2. There is no indication of what kind of objects could have caused the images except that they must be of a construction, design, and material not commonly known. This is indicated by the computed acceleration rate and elocity (answer 8). For the same reasons, birds, aircraft and balloons are ruled out. 3. An analysis of the charts relative to movement indicate that there were group and individual movement. Within a group it appears as if the individual objects were moving counter-clock-wise along an elliptical or similar track. Thus when two objects crossed the camera line of sight they will appear to fuse into one. As they continued along their paths it will appear as if one object became two. This occured at reglar intervals at approximately every 25th frame as plotted in charts 5a and 5b. DOWNGRADED AT 3 YEAR INTERVALS: DECLASSIFIED AFTER 12 YEARS.

All objects appear to have the same characteristics in regards to shape, color, size and relative motion. 5. The shape of the objects appears to be oblate or disk shaped, color; blue-white, and maximum and minimum size; 98 and 16 feet. The size is based on the assumption that the objects are five miles from the observer. 6. Fade in and fade out of the objects were analyzed as in 3 above. In this case the group movement was such that the distance between the objects and camera was increased so that the objects could not be recorded on the film thereby causing the apparent fade- out. Fade-in as attributed to a shortening of the distance from the fade-out area to the camera station. 7. Plots of the groups indicate that the objects move counter- clock-wise relative to the axis of flight path. However, nothing has been detected which indicates motion of the individual objects about their own axis although this motion appears to be likely. 8. In determining the velocity of the objects three assumptions were made: a. The camera was held steady during Part III of the film. b. The objects were moving perpendicular to the optical axis, and c. The objects were five miles from the camera. It is obvious that (b) is a fallacy; however, this assumption will give the minimum velocity and the actual velocity is greater than computed. The assumption that the objects are five miles from the camera is an arbitrary one. However, based on the emulsion speed and focal length, an object 50 feet in diameter and five miles from the camera will be recorded on the film with sufficient resolution to identify major details of the object. It is felt that if these objects were closer than five miles at the time of recording, details would appear on the film. Velocity is computed to be 3780 mph for a shift of 1 um per frame if the object is five miles from the observer.

These figures differ from those given in reference (c) and were computed from measurements obtained under more controlled conditions. Acceleration was determined from the formula : 8 = VI - VO where: T a = Acceleration Vi = final velocity VO = initial velocity T = time = 1/16 second Since "g" is equal to 32.17 ft/sec? it was computed that: Maximun acceleration = 21,163 mph/sec = 965 g Minimum acceleration = 1,104 mph/sec = 50 g Maximum deceleration = 32,448 mph/sec = 1479 g Minimum deceleration = 272 mph/sec = 12 g Velocit and acceleration determinations were also made from the Montana film. In this case, terrestial objects appeared in the film and were held to as control. Subsequently, the velocity and acceleration determinations are considered to be more reliable. On the assumption of (b) and (c) above the maximum and minimum velocities of the left object are 1374 and 361 mph respectfully. For the right object they are 1117 and 189 mph. Accelerations were computed as: Left Object Right Object Maximam acceleration mph/sec 14,016 = 639 g 12640 = 576g Minimum acceleration mph/sec 0 = 0 g 0 = 0g Maximum deceleration mph/sec 13,184 = 601 g 14288 = 651g Minimum deceleration mph/sec 0 - 0 g 0 = 0g The above determinations were made from a total of 322 measure- ments. It was noted that the acceleration and determinations were in multiples of 12.5 approximately. This may be of significance although no study has been conducted to determine this. Velocity and acceleration were treated in sub-paragraph 8 above. Paragraph 2a indicates the controls used during this investi- gation. DOWNGRADED AT 3 YEAR INTERVALS; DECLASSIFIED AFTER 12 YEARS.

There is no recurring pattern in the relative position of the objects in formation. It appears however, as if the shift in relative positions were regular and that the original formation would be recovered if the continuing action has been recorded. b. No. However, the same formation is maintained with objects changing positions. c. No detection of relative positions being maintained coincidental with movement about their axis. d. No detection of undulating motion of objects in phase either in formation or tumbling motion. e. There is evidence of abrupt changes in direction of flight path through fairly large angles. f. Certain objects do appear to remain motionless while other move about. 8. Certain objects disappear while still well within the field of view. This is discussed in sub-paragraph 6 above. 4. Discussion. During the study and investigation of the unidentified objects, the preliminary data uncovered were revealed to experts (with proper security clearance) in the fields of astronomy and physics. Although they presented certain natural phenomena theories to explain the cause of the objects under certain conditions they were not able to do so under the conditions during which the photography was taken, nor were they able to recognize these objects as man-made. As to the results of the investigations being reported, no attempt was made tocorroborate the opinions presented. Because of the lack of proper equipment, money and personnel, the investigation was limited. There are obvious tests which can be conducted to prove or disprove some of the findings presented. It is suggested that these be undertaken. 5. Reference (a) requests spectrophotometric analysis of the Utah film be made. Preliminary plan of test is underway.

UNCLASSIFIED him to make any estimates as to size, speed, or distance. Towerd the end of his observation one of the objects reversed course and proceeded awey from the rest of the group. He held the camera still and allowed this single objeet to pass across the field of view of the camera picking it up again later in its travel, He repeated this for two or three passes. By this time all the objects had disappeared. The movies have been studied by the Photo Recomnaissance Laboratory, Wright Air Development Center, Wright-Patterson AFB, Ohio, and by the U,S, Navy Photo Inter- pretation Center, Washington, D. C. Since there was no known object such as a cloud, tree, or mountain in the film, it was impossible to make even a rough estimate as to the speed, distance, or size. The size of the images on the movie film were too small to show any details. The movies have been studied by persons engaged in work with balloons and the appearance and action of the objects are similar to that of pillow balloons. These balloons are called pillow balloons due to their similarity to a pillow. Hundreds of these balloons were made and flown in the U.S. and overseas during the Crusade for Freedom, Attempts to trace these balloons to determine whether any left over fron the Crusade for Freedon could have been launched in the Tremonton area were negative. Another strong possibility is that the objects were sea gulls soaring thermal air current. * Movies of sea gulls taken under sintlar lighting conditions showed the sea gulls appearing as bright spots of light very similar to those in the movies. At the present time the Air Force contemplates no future action will be taken to identify the objects. DOWNGRADED AT & TWAR INTERVALS; DECLASSIFIED AFTER 12 YEARS.

Analysis of Photographic Material Serial 02 PHOTOGRAMMETRIC ANALYSIS OF THE "UTAH" FILM TRACKING UFO'S Several Unidentified Flying Objects (UFO's) were sighted and photo- graphed at about 11:10 MST on July 2, 1952 by Delbert C. Newhouse at a point on State Highway 30, seven miles north of Tremonton, Utah (latitude 41ยบ 50', longitude 112ยฐ 10'). Mr. Newhouse, a Chief Warrant Officer in the U. S. Navy *, was in transit from Washington, D. C. to Portland, Oregon. A map of the area is included as figure 1. He, his wife and their two children were making the trip by car. Shortly after passing through the city of Tremonton, his wife noticed a group of strange bright shining objects in the air off towards the east- She called them to her husband's attention and prevailed upon him to stop the car. When he got out, he observed the objects (twelve to fourteen of them) to be directly overhead and milling about. He described them as "gun metal colored objects shaped like two saucers, one inverted on top of the other". He estimated that they subtended "about the same angle as B-29's at 10,000 feet" (about half a degree - i.e., with a 3" telephoto lens, loaded it, focused it at infinity and began shooting. There was no reference point above the horizon so he was unable to estimate absolute size, speed or distance. He reports that one of the objects reversed its course and proceeded away from the rest of the group; he held the camera still and allowed this single object to pass across the field of view of the camera, picking it up later in its course. repeated this for three passes. Senys he During the filming, Newhouse changed the iris stop of the camera from $/8 to 1/16. The density of the film can be seen to change markedly at a point about 30% through the sequence (figure 5(b) at f/8 and the other blowups at f/16. The camera was operated at 16 fps. The color f1lm (Daylight Kodachrome) after processing was submitted to his superiors. The Navy forwarded the film to the USAF-ATIC where the film was studied for several months. According to Al Chop (then with ATIC and presently with DAC) Air Force personnel were convinced that the objects were not airplanes; on the other hand the hypothesis that the camera might have been out of focus and the objects soaring gulls could neither be confirmed nor denied. Mr. Chop's remarks are essentially substantiated by Capt. Eaward Ruppelt, reference (1) then head of Project "Blue Book" for ATIC. * At the time he had already logged sone 2,200 hours as a chief photographer with the Navy. DECLASSIFIED Authority NND 923007

Visual study of the reprints on the Recordak and astronomical plate measuring engine revealed the follow- the f1lm comprises about 1,200 frames; on most of the frames there appear many round white dots, some elliptical. The dots often seem clustered in constellations, or formations which are recognizable for as long as seven- A relative motion plot (obtained from an overlay vellum trace on the Recordak) of two typical formations are presented in figures 2a and 2b. The objects seem to cluster in groups of two's and three's, see actual blowups, 4a, 5b, and 6c. On some frames they flare up and then disappear from view in 0.25 seconds or less and sometimes they appear as a randomly scattered "twinkling" The dot images themselves show no structure; they are white and have no color fringes. Examination under a microscope shows the camera to be well focused as the edges of the images are sharp and clear on many of the properly exposed frames. Angular diameters range from about 0.0016 to 0.0004 radians. Their pattern of motion is essentially a curvi- linear milling about as shown in figure 2a and 2b. Sometimes the objects ap- pear to circle about each other. There are no other objects in the field of view which might give a clue as to the absolute motion of the cluster. In the overlay trace, figure 2, the frame of reference is determined by a certain object whose relative motion during a sequence of frames remains rather constant (indicated in the figures). This object is used as a refer- ence point and the lower edge of the frame as abscissa. Assuming the camera to have been kept reasonably uncanted, the abseissa would be horizontal and the ordinate vertical. In the overlay trace, figures 3a and 3b, the particular frame itself is used as the reference. Assuming the camera was held steady (there is an unconscious tendency to pan with a moving object) the coordinate system is quasi-fixed. It is realized that both of these coordinate systems are in actuality moving, possibly possessing both velocity and acceleration. No altitude or azimth determination can be made because of lack of background. The only measurable quantities of interest are therefore the relative angular distances between the objects and their time derivatives. Graphs of two typical time variations of relative angular separation and velocity are included as figures 7 and 8. The relative angular velocity is seen to vary from zero to 0.0065 radians per second. The relative angular acceleration had a maximan value of 0.0036 radians per second squared. Supposing the camera was kept stationary the average angular velocities for the object moving across the field are 0.039 and 0.031 radians per second for figures 3a and 3b. The angular velocities in these sequences sometimes vary erratically from 0.07 to 0.01 radians per second. This variation may be attributed in part to camera "jiggling" and in part to the object's ED Authority NND 923007

Photogrametric Analysis of "Utah" F1]m -3- Serial 02 motion. The decrease in average angular velocity between 3(a) and 3(b) could be due to the object's having regressed between filmings just as was reported by Newhouse. Also the average image diameter decreases about 30% over the entire f1]m, indicating a possible over-all regression of the objects. The following tabulation indicates the hypothetical transverse component of relative velocities and accelerations at various distances. It is noted that the transverse velocity may be only a fraction of the total velocity so that the mmbers actually indicate minimm values.

Photogrametric Analysis of "Utah" Film Serial 02 The image size being roughly that of the Montana film (a few of the objects being perhaps 10% larger than the largest on the Montana) the same remarks as to airplane reflections apply, i.e., they might have been caused by sun reflections from airplanes within one to three miles of the observer, although at these distances they should have been identified as conventional aircraft by the film or the observer. No specific conclusions as to sun reflection angles can be drawn since the line of motion of the objects cannot be confirmed. However, the reported E to W motion of the UFO and their pass- ing overhead coupled with the SE azimuth of the sun would make the achieve- ment of optimal sun reflections rather difficult. That the images could have been produced by aluntmum foil "chaff" * seems possible, at least on the basis of the images shown, as very intense specular sun reflections from ribbons of chaff might flare out to about the size of the UFO. Exemination of figures 4b, 5a, and 5c, obtained from the photogrammetric experiment -- reference Analysis of Photographic Material, Serial 01, Appendix II, show that no significant broadening is produced by flat white diffuse reflec- tors such as birds, bits of paper, etc. at f/16 under the conditions of the Actual measurements show a slight "bleeding" or flaring of about 10% to 20%. The rectangular flat white cardboards of the aforementioned experiments represented very roughly the configuration of birds. The light reflected by such a surface is probably greater than that from a curved feather surface of a bird.

At these distances, it is doubted if birds would give the appearance of round dots; also they would have been identifi- able by the camera if not visually. However, actual movies of birds in flight would have to be taken to completely confirm this conclusion. The following type of gulls have been known to fly at times over this locality: California Herring Gull (a common sumer resident), Ring-Billed Gull and the Fork-Tailed Gull, see reference (4). The images are probably not those of balloons as their mmber is too great and the phenomenon of flaring up to a constant brightness for several seconds, and then dying out again cannot well be associated with any known balloon observations. Bits of alumimm foil dumped overboard by planes, often utilized as a countermeasure against anti-aircraft radar. This material might possibly be in the form of large ribbons several feet long and several inches across. The dimensions refer to wing spread. The actual exposed white area of a bird is usually less and depends upon the perspective of the observer. This difference has been roughly accounted for in the data given, however, if the body were the principal reflector the distance given should be re- duced by a factor of 2 or 3.

Photogrammetric Analysis of "Utah" F11m Serial 02 Certain soaring insects - notably "ballooning spiders" (reference (5) and (6)) produce bright moving points of light. The author has witnessed such a phenomenon. It is produced by sun reflections off the streamers of silken threads spun by many types of spiders. Caught by the wind, these streamers serve as a means of locomotion floating the spider high They occasionally have the appearance of vast numbers of silken flakes which fill the air and in some recorded instances extend over many square miles and to a height of several hundred feet. The reflection, being off silk threads, is not as bright as diffuse reflection from a flat white board. no flaring of the images could be expected. The author noted that the sections of the "web" that reflected measured from 1/4" to 1/2" for the largest specimens. Thus the images might be attributed to balloon- ing spiders at distances of 50 to 100 feet. However, these web reflections ordinarily show up only against a rather dark background and it is doubted if their intensity would be great enough to produce the intense UFO images against a bright sky. No quantitative densitometer examination of image brightness could be made, as the original film was not available. It is understood from Al Chop thatยฎ the government analysts did make measurements of this kind on the original films and found the Utah images to be very intense *. Besides the above remarks, pertinent to the actual images, several facts can be gleaned from the motion of objects. The observations are not apt to support the supposition that the objects were conventional aircraft as the maneuvers are too erratic, the relative accelerations probably rul- ing out aircraft at distances of over five miles. Several observers familiar with the appearance of chaff have seen the film and concluded that the per- sistence of the nontwinkling constellations, their small quantity, and the reported absence of aircraft overhead makes chaff unlikely. Furthermore, the single object passing across the field of view would be most difficult to explain on the basis of chaff. These same remarks would apply also to bits of paper swept up in thermal updrafts. The relative angular velocity might be compatible with soaring bird speeds at distances of less than one mile, the angular velocity of the single object could be attributed to a bird within about one thousand feet. There is a tendency to pan with a moving object - not against it - so the velocities in the table probably represent a lower bound. the objects is not exactly what one would expect from a flock of soaring birds not the slightest indication of a decrease in brightness due to periodic turning with the wind or flapping) and no cumulus clouds are present which might betray the presence of a strong thermal updraft. hand the single object might represent a single soaring bird which broke away in search of a new thermal -- quite a common occurrence among gulle -- see reference (7). * In fact, "burned right down to the celluloid backing".

Photogrammetric Analysis of "Utah" F11m -6- Serial 02 That the air turbulence necessary to account for their movement if they were nearby inspects (even the single object's motion!) is possible, can be concluded from examination of reference (8). However, if the objects were nearby spider webs the lack of observed or photographed streamers is unusual. Furthermore, the fact that they were visible from a moving car for several minutes is hard to reconcile with localized insect activity. account for the images. Such a hypothesis is hampered by the clear weather conditions and the persistence and clarity of the images. Also no "shimmer- ing" can be detected and the motion is steady. Again the object which breaks away would be difficult to explain. It has been suggested that spurious optical reflections or light leaks in the camera might be responsible. Examples of such effects have been ex- amined and found to be quite different from the UFO's. The evidence remains rather contradictory and no single hypothesis of a natural phenomenon yet suggested seems to completely account for the UFO involved. The possibility of multiple hypotheses, i.e. that the Utah UFO's are the result of two simultaneous natural phenomena might possibly yield the answer. However, as in the case of the "Montana" analysis, no definite conclusion could be obtained. R. M. L. Baker, Jr. May 16, 1956 DECLAS

ANALYSIS OF 16 MA. MOTION PICTURE PHOTOGRAPHY OF UNIDENPIFTID ATRIAL OBJECIS. INTRODUCTION The motion picture was examined both by normal and slow motion projection, and by low power microscope. At the start it was found that the images are much too small to show any detail in the objects; the only eflect visible on the film by microscopic examination is a collection of small white spots. are frequently elongated in the direction of motion with respect to the camera position, but no other significant shape features can be seen. A Bell & Howell Model D-1-B projector was used to examine the motion of the objects. This projector permits the operator to reverse the motion during motor- driven projection, or to examine any length of film frame-by-frame, by means of a hand crank and frame counter. It was found that the objects are ten in number, in every one but the last of the motion sequences photographed. Occasionally some of these objects moved out of the camera's field of view momentarily. A list of questions, accompanying the recuest for this evaluation, are answered below. ANSWERS TO SLAIN CUESTIONS It cannot be stated definitely whether the objects are seen by reflected sunlight or because they are self-powered light sources. However, it can be de- duced that, if they are light-reflecting only, they are decidedly non-spherical in shape. During part of their flight paths they shine brightly, while at other times they are so dim as almost to escape detection. Furthermore, those objects which are following similar courses show similar brightness fluctuations, which could be caused by their taking similar flight attitudes. 2. It is believed to be reasonably certain that the reflection brightness of these objects exceeds that of any natural diffusing type of reflecting object, such as white birds against the sky. Also, there is no known bird that could is thought to be responsible. This statement, and the deduction of a non-spheri- cal shave, combine to rule out large translucent spherical balloons, but not bright aluminum-surfaced aircraft. Slow motion studies of the objects disclose that, in several instances, two objects on a nearly parallel course pass very close to each other, producing the blending effect. However, in each instance the two separate objects reappear after a moment. 4. and 5. As stated above, the only detail that can be seen is the small spot on the blue film, so no object shape can be determined. However, the maximum brightness of all the different spots appears to be the same, when they do become bright. The color at maximum brightness appears to be a clear white. At reduced brightness the spots remain essentially a neutral or grayish CLASSIFIED Authority NND 923007

white; no strong colors are noted. As to similar motion, a definite grouping of objects is noticeable. The first two sequences, taken with the sky as a light blue, show what probably are two groups of three objects each, and two groups of two each. The final sequence, against the dark blue sky, shows four pairs of objects, with the fifth pair having drifted upwards, out of the camera's field of view. 6. If the objects are reflecting, the "fade-in" and fade-out" are caused by changes in attitude of decidedly non-spherical objects, as in Answer 1 above. On the other hand, if they are light sources, the variation could be associated 7โ€ข and 8. As explained in the opening paragraph, the objects are only bright spots on the film. When they dim sufficiently, they become invis- ible; no dark spots can be identified with these oojects. The only visible motion in any single frame is with respect to the camera's field of view. Slow motion examination of successive frames suggests a general flight pattern of sweeping skew curves in space. This concept of object motions produces no sharp breeks in their apparent flight paths, and also makes it practically impossible to detect rapid accelerations or decelerations along these paths. 9. In the sequences during which the camera was held motionless, to record the angular velocity of a single object, it is possible to measure this velocity. Three such passes can be seen. The first was incomplete, picking up the object near the center of the frame. The second and third passes were complete, from one eage of the field of view to the other. Figure I shows the actual tracings of the object from frame to frame for both Passes No. 2 and No. 3โ€ข The distance from lens to screen was 100 inches. The focal length of the projection lens was 2 inches. The enlargement of Figure I over the actual negative size is therefore 50 times. Camera and pro- jector errors, plus small hand-held camera motions, probably account for the deviations from a straight line path. The average calculated angular velocity for both paths is about 2.1 degrees per second. Detailed computations are given in Appendix I. 10a. A slow motion viewing, plus single frane position plots, suggest that the objects are maneuvering in definite formations. However, successive identical positions are not indicated when position plots from any two frames in a sequence are superimposed. For instance, the first sequence of movement lasts 160 frames or 10 seconds. During the first seven seconds, clear plots for all 10 objects can be madรฉ. These plots were made at half second intervals or 8 frames apart. 10b. Figure II represents a possible set of flight paths for this interval, derived as explained in Appendix II. It should be remembered that Figure II very likely contains some indeterminate and non-constant camera motion, both horizontal and vertical, caused by tracking the formations. This means that the directions and curvatures as shown may be appreciably different from what a stationary camera would have recorded. However, Figure II does help visualize 2 DECLASSIFIED Authority NND 923007

โ” PAGE 102 โ”

the type of motion shown by the objects, moving from right to left, or generally from east to west as the camera was situated. This agrees with Figure I, show- ing the single object reversing course from left to right, or west to east. 10c and d. The relative positions of these objects in the first sequence follow a definite formation plan of either three pairs, a trio, and a single, or perhaps five pairs (if one of the trio and the single are actually a nearby pair). It appears that the objects tend to remain in position for curved path maneuvering. A possible shift in formation appears at the start of the trio paths. Otherwise, the objects definitely appear to undulate in phase in this sequence; as in the other sequences also. Several repeated slow motion viewings of the entire film do not indicate clearly any abrupt changes in flight path of any part of the fornation. At times the camera aupears to lag in following the entire group, and some of the ten objects then move outside the field of view momentarily. Whether or not a particular object remains motionless for a moment depends upon the relationship of group movement to camera movement. 10g. As explained in Paragraph 10f, sometimes objects may move out of the field of view. In a few instances, however, certain objects may change in brightness considerably, and practically appear or disappear well within the field of view. In the second sequence, which lasts about 14 seconds, the lower two pairs in Figure II flare up suddenly near the center of the field of view, being invisible a moment before. As they flare up, they appear to curve more rapidly to the left and upwards than the center trio. Reversing this sequence in slow motion shows that these four objects were faintly visible just before they disappeared at about the same position. A tabulation of flight sequences and durations is listed in Appendix III. CONCLUSIONS Subject motion picture film apparently records the motions of ten un- known aerial objects, all alike in observed characteristics of movement and size. 2. The exact nature of these objects cannot be determined, because they are visible only as small spots of light. It can be deduced, however, that they are either non-spherical in shape and similar to bright metal in reflectance, or else variably self-luminous by some means. 3. There is apparently a coordination of movement to some extent among these objects. They seem to move in fornations which are probably three-dimen- sional in arrangement. The largest angular size of the entire group is on the order of 6 to 8 degrees of arc. 4. The movements of these objects suggest flight paths consisting of skew curves in space. In one instance a single object changed course and followed a nearly straight line path with reasonable uniformity of notion at an angular velocity of about 2.1 degrees. During this straight line flight it remained reasonably uniform in brightness. DECLASSIFIED Authority NND 923007

STATEMENT BY SOURCE Place:- About 7 miles north of Tremonton, Utah, on U.S. Highway No. 305. Time:- 1110, Wednesday, 2 July 1952. Camera:- B&H Automaster, magazine load, 3" telephoto lens, 16 frames per second. Handheld. Exposure:- First few feet - f:8. Balance - f:16. Clear sun, cloudless sky. EKCO Kodachrone film - Daylight. Exposure was changed with the mistaken idea of darkening the sky to gain greater contrast. The result was merely general underexposure. Background:- Driving from Washington, D.C., to Portland, Oregon, on the morning of 2 July, my wife noticed a group of objects in the sky that she could not iden- tify. She asked me to stop the car and look. There was a group of about ten or twelve objects that bore no relation to anything I had seen before, milling about in a rough formation and proceeding in a westerly direction. I opened the luggage compartment of the car and got my camera out of a suitcase. Load- ing it hurriedly, I exposed approximately thirty feet of film. There was no reference point in the sky and it was impossible for me to nake any estimate of speed, size, altitude or distance. Toward the end one of the objects re- versed course and proceeded away from the main group. I held the camera still and allowed this single one to cross the field of view, picking it up again and repeating for 3 or 4 such passes. By this time all of the objects had disappeared. I expended the balance of the film late that afternoon on a mountain somewhere in Idaho. erla DECLASSIFIED Authority NND 923007

Appendix I Calculation of Angular Velocity of Single Aerial Object: Pass No. 2: 48 spot positions are plotted, representing an elapsed time interval 01 47 tranes. At 16 franes per second, this gives: 47 3.0 seconds elapsed time 16 The measured distance on the screen is 15.1 inches. This gives approximately 15.2 or 5.0 inches per second for image velocity on the screen. 3.0 Pass No. 3: 44 spot positions are plotted, for 43 frames of elapsed time. This time is 43 2.7 seconds. 16 = The distance travelled is 15.7 inches. This gives 15.7 15.7 = 5-8 inches per second on the screen. Average of these 2 values is 5.4 inches per second; with an es- timated precision of +15 per cent. Conversion to Angular Velocity: Distance from projector lens to screen = 100 inches Focal length of projector lens = 2 inches Enlargement of film on screen = 50 times Image velocity on film = 5.4 30 = 11 inches per second Focal length of camera taking lens = 3 inches It is adequately precise to divide the image velocity by the focal length to get the angular velocity in radians per second, then to convert to degrees. We have: Angular velocity = 11 x 57-3 = 2.1 degrees per second The precision of this value is also conservatively set at $15% or 10.3 degrees per second. DECLASSIFIED Authority NND 923007

Appendix II Plotting a Set of Flight Paths from Single Frane Position Plots, with no Reference Points 1. In a case like this, it would be highly desirable if the movement of these objects could be recorded with a stationary motion picture camera. Position plots could be superimposed by observing proper registery of frame edges to in- dicate the speed and direction of object flight paths. However, it apparently was necessary in this case to follow the form- ation of objects, to keep them all in view. Therefore no position guide for registering the position plots is available, since no fixed points appear in the sky. Other principles must be used instead. 3. It is stated that the general drift of the entire formation was to the A later secuence shows a single object, which had reversed course, moving from left to right in the camera's view. It can therefore be supposed that plotted paths should show a drift from right to left. 4. This is one guide to be used. Another is that position plots should be super imposed without any rotation, since the frames were plotted without rotation. This assumes that the camera was not rotated; but merely moved in combined horizontal and vertical motions. 5. Another general guide is that most of the objects should appear to move in smooth, continuous paths. Several plots, at least 4, should be superimposed on a viewing table, and should be shifted until all or nearly all paths are smooth and show reasonably uniform motion. This compound plot can be transferred to a single sheet, and further plots can be added in the same manner. Figure ll was prepared in just this way, using the same 50 diameter en- largement as in Figure I. It will be noted that the final positions of two objects in the central trio are missing. They became so faint that they were lost; no further plotting of this sequence was tried. DECLASSIFIED Authority NND 923007

Is there any bird sufficiently actinic to cause images? Could they have been caused by aircraft or balloons? 3. What causes the impression that some objects at times appear to become 2 or 3 objects, at times appear to merge into one? 4. Do all objects have same characteristics? 8. b. c. Same apparent shape? Same relative size? Same Color? Same general motion? 5. What are shape(s), colors), and relative size(s) of objects? 6. To what can the "fade-in" and "fade-out" of the objects be attri- buted? 7โ€ข What type motion is attributable to the objects (about their own axis as well as about the axis of flight path)? 8. Is there any acceleration evident in their motion along flight path axis? 9. Can the motion of the camera (panning and joggling) be allowed for sufficiently to permit deternination of the angular velocity of objects which cross the field of view? (Reference particularly the single object which crosses field; photographer states that camera was held motionless while ob- ject crossed field of view.) 10. Deternine patterns of flight from position plots for each frame, then: a. Is there any recurring pattern in the relative position of the objects? b. Do they maintain same relative positions in formation during any maneuvers, particularly violent maneuvers? Is relative position maintained coincidental with movement about C. their axes? If undulating motion is present among a number of objects which are maintaining a semblance of formation, do those objects undulate in phase? Ditto for tumbling motion. e. Is there any indication of abrupt changes in direction of flight path through fairly large angles (eg., 90ยบ or more during interval of 2 or 3 frames)? DECLASSIFIED Authority NND 923007

(Reference particularly the single object which crosses field; photographer states that camera was held motionless while object crossed field of view.) j. Determine patterns of flight from position plots for each frame, then: (1) Is there any recurring pattern in the relative position of the objects? (2) Do they maintain same relative positions in formation during any maneuvers, particularly violent maneuvers? (3) Is relative position maintained coincidental with movement about their axes? (4) If undulating motion is present among a number of objects which are maintaining a semblance of formation, do those objects undulate in phase? Ditto for tumbling (5) motion? Is there any indication of abrupt changes in direction of flight path through fairly large angles (e-g. 90ยฐ or more during interval of 2 or 3 frames)? (6) Do any objects appear to remain motionless at the same time that others move about? (7) Can all objects be accounted for at all times or do some literally disappear while still well within field of view? 6. Although CPO Newhouse did not request that the film be returned to him, it is recommended that the final footage (of the mountain scenery) be returned to him immediately and that he be asked if he is willing to accept a duplicate of the initial footage in lieu of the original. If his reply is affirmative, suggest the duplicate be forwarded whenever available. 7. Request advice of the analytical results as soon as available. Millain G. Adams 2 Incls: (w/orig only) 1.

Enclosure (1) is forwarded herewith for whatever value it may have in con- nection with your investigation of the so-called "Flying Saucers". Pertinent data follows: Place: Time: Camera: Exposure: About 7 milesnorth of Tremonton, Utah on U. S. Highway No. 30S. 1110 Wednesday 2 July 1952. B&H Automaster, magazine load, 3" telephoto lens, 16 frames per second. Handheld. First few feet - {:8. Balance - {:16. Clear sun, cloudless sky. EKCo Kodachrome film - Daylight. Exposure was changed with the mistaken idea of darkening the sky to gain greater cort rast. The result was merely general under exposure. General Background: Driving from Washington, D. C. to Portland, Oregon, on the morning of 2 July my wife noticed a group of objects in the sky that she could not identify. She asked me to stop the car and look. There was a group of about ten or twelve objects - that bore no relation to anything I had seen before - milling about in a rought formation and proceeding in a westerly direction. I opened the luggage compartment of the car and got my camera out of a suit- case. Loading it hurriedly, I exposed approximately thirty feet of film. There was no reference point in the sky and it was impossible for me to make any estimate of speed, size, altitude or distance. Toward the end one of the objects reversed course and proceeded away from the main group. I held the camera still and allowed this single one to cross the field of view, picking it up again and re- peating for three or four such passes. By this time all of the ob- jects had disappeared. I expended the balance of the film late that afternoon on a mountain somewhere in Idaho. /s/ Delbert C. Newhouse DECLASSIFIED Authority NND 923007

Mr. M. A. Monts, Air Force Press Room, Room 2E761, Pentagon TREMONTON Mr. M. A. Monts Air Force Press Room Room 2E761, Pentagon 1 June 1956 MEMORANDUM FOR DIRECTOR OF INTELLIGENCE Atta: Lt Colonel T. R. Johnson, AFOIN-X SUBJECT: (Uncld) UFO Movie 1. The following statements concerning two of the UFO sightings described in the recently released movie, are sub- mitted in response to Mr. Monts' request of 29 May 1956. a. The Marianna Case - Montana - 1950. The original Air Force conclusion, based on the interrogation of witnesses and the evaluation of the data, was that the UFOs were, in all probability, two Air Force F-9 fighter aircraft known to be in the vicinity at the time. Simulated photographs of aircraft at various distances, made by an aircraft manufacturing firm in a recent independent and unsolicited analysis of the Marianna film, show striking similarity to the two white blops in this film. Based on the degree of credibility accorded this early ATIC evaluation and the strong corroborative evidence supplied by the recent independent analysis, the Air Force has no com- pelling reason to alter its original conclusion. b. The Newhouse Case - Utah - 1952. The original film was analyzed by an Air Force Photo Reconnaissance Laboratory shortly after the sighting. The conclusion reached was that a strong possibility existed that the bright spots of light appearing on the film were caused by seagulls soaring in thermal air cur- rents. The credibility of the conclusion was undoubtedly sup- ported by the presence of identifiable seagulls in some of the frames. This conclusion was further strengthened by movies of seagulls, taken at various distances, which showed them as bright spots of light similar to those in the Newhouse film.

Memo to D/I (OIN-X), (U) UFO Movie, 1 Jun 56 A recent analysis of the Newhouse film, made by Air Force photo specialists totally unaware of the previous history of this case, yielded the opinion that the bright spots of light on the film were bird reflections in the strong sunlight. The unanimity of opinion present in all evaluations made in this case leaves little reasonable doubt that the UFOs in the Newhouse film were indeed seagulls. 2.

Tests and Procedure. The film exposed in Utan 1s in very poor condition; dry, brittle and with a tendency to break. After initial viewing, duplication of the f1lm was performed in order to preserve the one originally re- ceived. This consumed approximately two weeks. In the duplication process, some color correction was made to permit better viewing of the objects. For conventence in interpretation, the f1lm was divided into three parts, each part being considered an entity.

Light Source. The opinion that these images are light sources is based on the time they can be viewed imately 60 degrees. It is felt that if these images were when photographed at the rate of 16 frames per second. Although this premise would permit aircraft and balloons determination. to permit velocities of present aircraft, they would be close enough for positive identification. If they are too far away for positive identification, then the velocity is too great for any aircraft as we know them. b. Color. Colors were noted as shades of red, green, blue and bluish-white.

0263 UNCLASSIFIED DEC 5 1952 the bluish-white, the colors noted are due to color aber- rations in the lens and to processing defects, and are not of the objects themselves which can be observed throughout the entire or major portion of the film. It should be pointed out at this point that unless an image appeared in at least five successive frames, it was regarded as a pro- cessing defect. Velocity. In the determination of the velocity of the objects, two assumptions were made; (a) the camera is greater than computed. It may be possible to apply a correction factor after the completion of the stereoscopic study, although this is doubtful. With these assumptions and knowing the focal length of the camera, the only unknown in the determination of the velocity is the distance from the observer to the object. This was arbitrarily set at five miles. Size, Pattern and Formation. Analysis has not progressed to the stage where the relative sizes of these images can be stated. This applies also to patterns and formations although it appears as if they do occur. is expected that stereoscopic analysis of the objects will furnish much information on this subject. Reference (b) requested interpretation of additional the movie. One plot was made of the light path in the area where stationary objects are visible to hold to as control. Analysis of this movie is not sufficiently complete to offer any comment other than the path of light is undulating and is similar to that plotted for the Utah movie.

Location and actual distance of observer to the center of the tower. c. Dimensions of the tower. d. Lengths of bracing on the tower.

ANATYSIS OF 16 MM. MOTION PICTURE PHOLOGRAPHY OF UNIDENTIFIED ADRIAL OBJECIS. INTRODUCTION The motion picture was examined both by normal and slow motion projection, and by low power microscope. At the start it was found that the images are much too small to show any detail in the objects; the only effect visible on the film by microscopic examination is a collection of small white spots. They are frequently elongated in the direction of motion with respect to the camera position, but no other significant shape features can be seen. A Bell & Howell Model D-1-B projector was used to examine the motion of the objects. This projector permits the operator to reverse the motion during motor- driven projection, or to examine any length of film frame-by-frame, by means of a hand crank and frame counter. It was found that the objects are ten in number, in every one but the last of the motion sequences photographed. Occasionally some of these objects moved out of the camera's field of view momentarily. A list of questions, accompanying the request for this evaluation, are answered below. ANSWERS TO STATED QUESTIONS 1. It cannot be stated definitely whether the objects are seen by reflected sunlight or because they are self-powered light sources. However, it can be de- duced that, if they are light-reflecting only, they are decidedly non-spherical in shape. During part of their flight paths they shine brightly, while at other times they are so dim as almost to escape detection. Furthermore, those objects which are following similar courses show similar brightness fluctuations, which could be caused by their taking similar flight attitudes. 2. It is believed to be reasonably certain that the reflection brightness of these objects exceeds that of any natural diffusing type of reflecting object, such as white birds against the sky. Also, there is no known bird that could emit such a radiation as would be required to produce the observed brightness. Either a large metallic surface of nearly flat shape, or a self-luminous source, is thought to be responsible. This statement, and the deduction of a non-spheri- cal shape, combine to rule out large translucent spherical balloons, but not bright aluminun-surfaced aircraft. Slow motion studies of the objects disclose that, in several instances, two objects on a nearly parallel course pass very close to each other, producing the blending effect. However, in each instance the two separate objects reappear after a moment. 4. and 5. As stated above, the only detail that cen be seen is the small bright spot on the blue film, so no object shape can be determined. However, the maximun brightness of all the different spots appears to be the same, when they do become bright. The color at maximun brightness appears to be a clear white. At reduced brightness the spots remain essentially a neutral or grayish enel 3' DECLASSIFIED Authority NND 923007

white; no strong colors are noted. As to similar motion, a definite grouping of objects is noticeable. The first two sequences, taken with the sky as a Light blue, show what probably are two groups of three objects each, and two groups of two each. The final sequence, against the dark blue sky, shows four pairs of objects, with the fifth pair having drifted upwards, out of the camera's field of view. 6. If the objects are reflecting, the "fade-in" and fade-out" are caused by changes in attitude of decidedly non-spherical objects, as in Answer 1 above. On the other hand, if they are light sources, the variation could be associated with their maneuvering activity. 7. and 8. As explained in the opening paragraph, the objects are only small bright spots on the film. When they dim sufficiently, they become invis- ible; no dark spots can be identified with these objects. The only visible motion in any single frame is with respect to the camera's field of view. Slow motion examination of successive frames suggests a general flight pattern of sweeping skew curves in space. This concept of object motions produces no sharp breaks in their apparent flight paths, and also makes it practically impossible to detect rapid accelerations or decelerations along these paths. 9. In the sequences during which the camera was held motionless, to record the angular velocity of a single object, it is possible to measure this velocity. Three such passes can be seen. The first was incomplete, picking up the object near the center of the frame. The second and third passes were complete, from one edge of the field of view to the other. Figure I shows the actual tracings of the object from frame to frame for both Passes No. 2 and No. 3. The distance from lens to screen was 100 inches. The focal length of the projection lens was 2 inches. The enlargement of Figure I over the actual negative size is therefore 50 times. Camera and pro- jector errors, plus small hand-held camera motions, probably account for the deviations fron a straight line path. The average calculated angular velocity for both paths is about 2.1 degrees per second. Detailed computations are given in Appendix I. 10a. A slow motion viewing, plus single frame position plots, suggest that the objects are maneuvering in definite formations. However, successive identical positions are not indicated when position plots from any two frames in a sequence are superimposed. For instance, the first sequence of movement lasts 160 frames or 10 seconds. During the first seven seconds, clear plots for all 10 objects can be made. These plots were made at half second intervals or 8 frames apart. 10b. Figure II represents a possible set of flight paths for this interval, derived as explained in Appendix II. It should be remembered that Figure II very likely contains some indeterminate and non-constant camera motion, both horizontal and vertical, caused by tracking the formations. This means that the directions and curvatures as shown may be appreciably different from what a stationary camera would have recorded. However, Figure II does help visualize 2 DECLASSIFIED Authority NND 923007

the type of motion shown by the objects, moving from right to left, or generally from east to west as the camera was situated. This agrees with Figure I, show- ing the single object reversing course from left to right, or west to east. 10c and d. The relative positions of these objects in the first sequence follow a definite formation plan of either three pairs, a trio, and a single, or perhaps five pairs if one of the trio and the single are actually a nearby pair). It appears that the objects tend to remain in position for curved path maneuvering. A possible shift in fornation appears at the start of the trio paths. Otherwise, the objects definitely appear to undulate in phase in this sequence; as in the other sequences also. particular object remains motionless for a monent depends upon the relationship of group movement to camera movement. 10g. As exolained in Paragraph 10f, sometimes objects may move out of the field of view. In a few instances, however, certain objects may change in brightness considerably, and practically appear or disappear well within the field of view. In the second sequence, which lasts about 14 seconds, the lower two pairs in Figure II flare up suddenly near the center of the field of view, being invisible a moment before. As they flare up, they appear to curve more rapidly to the left and upwards than the center trio. Reversing this sequence in slow motion shows that these four objects were faintly visible just before they disappeared at about the same position. A tabulation of flight sequences and durations is listed in Appendix III. CONCLUSIONS 1. Subject motion picture film apparently recoras the motions of ten un- known aerial objects, all alike in observed characteristics of movement and size. 2. The exact nature of these objects cannot be determined, because they are visiole only as small spots of light. It can be deduced, however, that they are either non-spherical in shape and similar to bright metal in reflectance, or else variably self-luminous by some means. 3. There is apparently a coordination of movement to some extent among these objects. They seem to move in formations which are probably three-dimen- sional in arrangement. The largest anguler size of the entire group is on the order of 6 to 8 degrees of arc. 4. The movements of these objects suggest flight paths consisting of skew curves in space. In one instance a single object changed course and followed a nearly straight line path with reasonable uniformity of motion at an angular velocity of about 2.1 degrees. During this straight line flight it remained reasonably uniform in brightness. DECLASSIFIED Authority NND 923007

Appendix I Calculation of Angular Velocity of Single Aerial Object: Pass No. 2: of 47 frames โ€ข 48 spot positions are plotted, representing an elapsed time interval At 16 frames per second, this gives: 47 3.0 seconds elapsed time 16 = The measured distance on the screen is 15.1 inches. This gives approximately or 5.0 inches per second for image velocity on the screen. Pass No. 2: 44 spot positions are plotted, for 43 frames of elapsed time. This time is 43 2.7 seconds. The distance travelled is 15-7 inches. This gives 15-7 2.7 = 5.8 inches per second. on the screen. Average of these 2 values is 5.4 inches per second; with an es- timated precision of +15 per cent. Conversion to Angular Velocity: Distance from projector lens to screen = 100 inches Focal length of projector lens = 2 inches Enlargement of film on screen = 50 times Image velocity on film = 5.4 50 = 111 inches per second Focal length of camera taking lens = 3 inches It is adequately precise to divide the image velocity by the focal length to get the angular velocity in radians per second, then to convert to degrees. We have: Angular velocity = 11 x 57.3 = 2.1 degrees per second The precision of this value is also conservatively set at $15% or 10.3 degrees per second. DECLASSIFIED Authority NND 923007

Appendix II Plotting a Set of Flight Paths from Single Frame Position Plots, with no Reference Points In a case like this, it would be highly desirable if the movement of these objects could be recorded with a stationary motion picture camera. Position plots could be superimposed by observing proper registery of frame edges to in- dicate the speed and direction of object flight paths. 2. However, it apparently was necessary in this case to follow the form- ation of objects, to keep them all in view. Therefore no position guide for registering the position plots is available, since no fixed points appear in the sky. Other principles must be used instead. 3. It is stated that the general drift of the entire formation was to the west. A later sequence shows a single object, which had reversed course, moving from left to right in the camera'sview. It can therefore be supposed that plotted paths should show a drift from right to left. 4. This is one guide to be used. Another is that position plots should be superimposed without any rotation, since the frames were plotted without rotation. This assunes that the camera was not rotated; but merely moved in combined horizontal and vertical motions. 5โ€ข Another general guide is that most of the objects should appear to move in smooth, continuous paths. Several plots, at least 4, should be superimposed on a viewing table, and should be shifted until all or nearly all paths are smooth and show reasonably uniform motion. This compound plot can be transferred to a single sheet, and further plots can be added in the same manner. 6. Figure II was prepared in just this way, using the same 50 diameter en- largement as in Figure I. It will be noted that the final positions of two objects in the central trio are missing. They became so faint that they were lost; no further plotting of this sequence was tried. DECLASS Authority NND 923007
