USAF Fact Sheet 95-03
Unidentified Flying Objects and Air Force
Project Blue Book
From 1947 to 1969, the Air Force investigated Unidentified Flying
Objects under Project Blue Book. The project, headquartered
at Wright-Patterson Air Force Base, Ohio, was terminated
Dec. 17, 1969. Of a total of 12,618 sightings reported to
Project Blue Book, 701 remained "unidentified."
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;"
National Academy of Sciences; previous UFO studies and
Air Force experience investigating UFO reports during the
1940s, '50s and '60s.
As a result of these investigations, studies and experience
gained from investigating UFO reports since 1948, the
conclusions of Project Blue Book were: (1) no UFO reported,
investigated and evaluated by the Air Force was ever an
indication of threat to our national security; (2) there was
no evidence submitted to or discovered by the Air Force that
sightings categorized as "unidentified" represented
technological developments or principles beyond the range of
modern scientific knowledge; and (3) there was no evidence
indicating that sightings categorized as "unidentified" were
extraterrestrial vehicles.
With the termination of Project Blue Book, the Air Force
regulation establishing and controlling the
program for investigating and analyzing UFOs was rescinded.
Documentation regarding the former Blue Book investigation
was permanently transferred to the Modern Military Branch,
National Archives and Records Service, Eighth Street and
Pennsylvania Avenue, N.W., Washington, D.C. 20408, and is
available for public review and analysis.
Since the termination of Project Blue Book, nothing has
occurred that would support a resumption of UFO investi-
gations by the Air Force. Given the current environment of
steadily decreasing defense budgets, it is unlikely the Air
Force would become involved in such a costly project in the
foreseeable future.
There are a number of universities and professional scientific
organizations that have considered UFO phenomena during
periodic meetings and seminars. A list of private
organizations interested in aerial phenomena may be found in
Gale's Encyclopedia of Associations. Interest in and timely
review of UFO reports by private groups ensures that sound
evidence is not overlooked by the scientific community.
Persons wishing to report UFO sightings should be advised
to contact local law enforcement agencies.
