CIA Office Memorandum: Unidentified Flying Objects (3 July 1953)

This two-page CIA Office Memorandum, dated 3 July 1953, was authored by the Chief of the Physics & Electronics Division of the Office of Scientific Intelligence (SI) and addressed to the Assistant Director, SI. It responds to an earlier memorandum of 27 May 1953 that had assigned the Division responsibility for maintaining current knowledge of reports of sightings of unidentified flying objects. The Division reviewed the project's status, method of handling, and relationship to its productive intelligence activities, holding informal discussions with OSD personnel, an OCI officer (Heckert), USAF personnel, and members of a Scientific Review Board convened by CIA the previous year. The review found that a thorough follow-up would require continuous effort from two analysts, a file clerk, and considerable typing. Citing the Board's finding that available material did not indicate a serious, direct threat to national security, the memorandum concluded that the project would be considered inactive, that incoming material would be reviewed periodically to separate explainable phenomena from genuine unidentified flying objects, and that all UFO material would be deposited in files for future reference unless it raised an immediate national security concern. The project would thereafter be handled with part-time use of an analyst and a file clerk, requiring one additional filing cabinet.
