MWRANDUM FOR: Director of Central Intelligence
a URJECT: 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 re-
ports of (UFO's (unidentified flying objects) in news media.
Widely publicized UFO reports during the past 18 months
Include: the July 1963 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 1964, in which two objects were apparently tracked
by radar, but later analysis attributed the sighting to
malfunctioning radar circuitry. Evaluation of these and
other reported phenomena reveals no evidence that UFO's are
of foreign origin or are a threat to the security of the
United States.
3. The Office of Scientific Inte?li.gence/DD 6&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 investiga-
tors. Of some 521 I reports Investigated during 1964, only
3% are classed 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.
