Memorandum for the Director of Central Intelligence: Unidentified Flying Objects

This document is a collection of internal CIA memoranda and correspondence from December 1952 regarding the investigation of Unidentified Flying Objects (UFOs). The primary memorandum, dated 13 December 1952, from the Assistant Director of Scientific Intelligence to the Director of Central Intelligence, summarizes a recent trip to the Air Technical Intelligence Center (ATIC). The intelligence community concluded that there was no evidence that the objects were of foreign origin or posed a direct threat to national defense. However, due to the potential risks associated with these sightings, the CIA initiated plans to assemble a panel of top-level scientific consultants in physics and astronomy to establish better methodologies for investigation, data collection, and rapid identification. The document includes detailed reports on specific cases, such as the 'Tremonton, Utah' film, which was under examination by the U.S. Navy Photo Interpretation Laboratory, and a sighting near Presque Isle and Limestone Air Force Base, which was suspected to be the planet Jupiter. Another case involved a reported encounter in Florida, which was deemed suspicious due to the source's background. The correspondence also includes a letter from Thornton Page of the Operations Research Office to Dr. H. P. Robertson, discussing the potential use of meteor patrol cameras and radar for tracking unidentified objects, as well as the psychological aspects of public reporting and false alarms. The documents reflect a period of intense internal debate within the intelligence community regarding how to scientifically approach the UFO phenomenon while managing the lack of substantive data.
