r Approved For Release 2002/10/29 : CIA-RDP68R00530A000200Q4100 DD/S&T 370/65 6 ti ray '~f 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. 25X1A MINALD F.
