This 1958 CIA memorandum, dated 9 January 1958, is an internal communication from the Chicago Office addressed to the Chief of the Contact Division's Support Branch. It documents a telephone conversation with Dr. Leon Davidson regarding a "space message and its transmitter," records for which the CIA states were destroyed by the evaluating agency. Davidson acknowledged having heard this explanation before and indicated he had a second article on Air Force handling of "space sightings" in preparation. He also hinted at revisiting the matter at a later date.
The document is notable for several reasons. The CIA explicitly acknowledges that its personnel concealed their agency identity from Davidson during prior contacts, while suspecting Davidson likely knew he was dealing with the CIA regardless. The memo candidly admits the answer given to Davidson was "evasive" and unlikely to satisfy him. A redacted version was previously publicly available; this release appears to restore previously withheld content. The destruction of records related to the "space message and its transmitter" is unaddressed and unverified within the document itself.
