tin Y rz t ' | UFO FACT SHEET On December 17, 1969 the Secretary of the Air Force announced the termination of Project Blue Book, the Air Force program for the investigation of UFOs. The decision to discontinue UFO investigations was based on an evaluation of a report prepared by the University of Colorado entitled, "Scientific Study of Unidentified Flying Objects;" a review of the University of Colorado's report by the National Academy of Sciences; past UFO studies; and Air Force experience investigating UFO reports during the past two ‘decades. As a result of these investigations and studies, and experience gained from investigating UFO reports since 1948, the conclusions of Project Blue Book are: (1) no UFO reported, investigated, and evaluated by the Air Force has ever given any indication of threat to our national security; (2) there has been no evidence submitted to or discovered by the Air Force that sightings categorized as "unidentified" represent technological developments or principles beyond the range of present day scientific knowledge; and (3) there has been no evidence indicating that sightings categorized as "unidentified" are extraterrestrial vehicles. With the termination of Project Blue Book, the Air Force regulation establishing and controlling the program for invest- igating and analyzing UFOs was rescinded. All documentation regarding the former Blue Book investigation has been per- manently transferred to the Modern Military Branch, National Archives and Records Service, 8th and Pennsylvania Avenue, Washington, D.C. 20408, and is available for public review and analysis. Attached for your information is the Project Blue Book sighting summary for the period 1947-1969. Also included is a listing of UFO-related materials currently available. Since the termination of Project Blue Book, no evidence has been presented to indicate that further investigation of UFOs by the Air Force is warranted. In view of the consider- able Air Force commitment of resources in the past, and the extreme pressure on Air Force funds at this time, there is no likelihood of renewed Air Force involvement in this area.
