Evaluation of UFO S

Central Intelligence Agency · 2002-10-09 · 3 pages · text by GLM-OCR

This Central Intelligence Agency memorandum, dated 26 January 1965 and released in 2002, was sent by Donald F. Chamberlain, Assistant Director for Scientific Intelligence, to the Director of Central Intelligence. It reviews recent publicized reports, including the 1963 Sunnyvale incident, the 1964 Gemini launch and the December 1964 Patuxent radar case. It finds no evidence that UFOs are foreign or a security threat and concurs with Air Force conclusions. Attached Air Force statistics cover 1954 to 1964.
