This Central Intelligence Agency memorandum, dated 26 January 1965 and released in 2001, was sent by Donald F. Chamberlain, Assistant Director for Scientific Intelligence, to the Director of Central Intelligence. It reviews recent UFO reports, including incidents at Sunnyvale, California, the Gemini launch and Patuxent, Maryland, and finds no evidence that UFOs are of foreign origin or a threat to United States security.

MEMORANDUM FOR: Director of Central Intelligence
SUBJECT: Evaluation of UFO's
1. This memorandum is for your information in response to your request.
2. As you know, there has been a recent spate of reports of UFO's (unidentified flying objects) in news media. Briefly publicized UFO reports during the past 16 months include: the July 1983 Sunnyvale, California, incident in which the UFO was later identified as an aircraft; the UFO's reportedly associated with the Gemini launching in April 1964 which probably were due to fragments causing radar reflection; and the Patuxent, Maryland, incident in December 1984, in which two objects were apparently tracked by radar, but later analysis attributed the sighting to anfunctioning radar circuitry. Evaluation of these and other reported phenomena reveals no evidence that UFO's are of foreign origin or are a torrent to the security of the United States.
5. The Office of Scientific Intelligence/EDS&T monitors reports of UFO's, including the official Air Force investiga tion reports, and concurs with the Air Force conclusions, which are unclassified and available to scientific investigators. Of some 521 UFO reports investigated during 1964, only 32 are claused as unidentified; 11 investigations are still pending. Attached are the official Air Force statistics for the time period 1954-1963 by year and for 1964 by month.
