The project, headquartered at Wright-Patterson Air Force Base, Ohio, was
terminated December 17, 1969. Of the total of 12,618 sightings reported to
Project Blue Book, 70l remain "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;" a review of the University of Colorado's
report by the National Academy of Sciences; previous UFO studies; and Air
Force experience investigating UFO reports during the l940's, '50's and '60's.
As a result of experience, investigations. and studies since 1948. the
conclusions of Project Blue Book were: (l) no UFO reported, investigated.
and evaluated by the Air Force was ever a 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 USAF regulation establishing
and controlling the program for investigating and analyzing UFO's was
rescinded. Documentation regarding the former Project Blue Book
investigation was permanently transferred to the Modern Military Branch,
National Archives and Records Service, in Washington, DC 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 investigations by the USAF or NASA.
Given the current environment of steadily decreasing defense and space budgets,
it is unlikely that. the Air Force or NASA \vill become involved in this type of
costly project in the foreseeable future.
Since neither NASA nor the Air Force is engaged in day-to-day UFO research,
neither one reviews UFO-related articles intended for publication, evaluates
UFO-type spacecraft drawings, or accepts accounts of UFO sightings or
applications for emplo�ent in the field of aerial phenomena investigation.
