This is a US Air Force UFO fact sheet dated 11 August 1985. It traces Air Force UFO investigations from Project Sign in 1948 through Project Grudge to Project Blue Book, which examined 12,618 sightings, 701 of which remained unexplained. A table lists the totals for each year from 1947 to 1969. The sheet says Blue Book ended in 1969, based partly on the University of Colorado study and the National Academy of Sciences review, and found no threat and no evidence of extraterrestrial vehicles.

On Dece~~e~ 17, 1969 the Secretary of the Air Force announced the
termination of Project Blue Book.
ThP decision tO discontinue UfQ i~Vestigations was based On an
evalYation of a report prepared by the Unive~sity of Colorado entitled,
"Scientific Study of~nidentified Flying Objects;" a review or the Univer-
sity of Colorado's report by the National Academy or Sciences; past
UFO studies; and Air Force experienc~ investigating UFO reports for
two decades.
As a result or these investigations and stu·~ies, and expe~ience
gained fro~ investigating UFO reports since ,948, the conclusions or
Project Blue Book were: (1) no UFO reported, investigated, and evalu-
ated by the Air Fo~ce has ever given any indication of threat to our
national security; (2) there has been no evidence submitted to or d1s-
cov~red by the Air Force that sightings categorized •s ~unidentified"
represent technological developments or principles beyond the range
or present day scientific knowledge; and (3) there has been no evidence
indicating that sightings categorized as "unidentified" are extrater-
restrial vehicles.
With the termination or Project Blue Book, the Air Force regulation
establishing and controlling the program for investigating and analyzing
UFOs was rescinded. All documentation regarding the former Blue Book
investigation was permanently transferred to the Modern Military Branch,
National Arch\ves and Records Service, 8th and Pennsylvania Avenue,
Washington, D.C. 20408, and is available for public review and analysis •..
In 1977, President Cart~r asked the National Aeronautics and Space
Administ~ation (NASA) to look into the possibility of resuming UFO investi-
ga~ions After studying all the facts available, they decided that
nothi~~ woul~ be gained by further investigation. The Air Force agrees
w!t~ th~t decisior.. If, however, firm evidence is found justifying
r~~the~ investigation, an appropriate agency will be directed to under-
take the error+:..
There are a number or universities and professional scientific
organizations such as the American Association for the Advancement of
Science, which have considered UFO phenomena during periodic meetings
anc se~inars. In addition, a list or private organizations inte~ested
in aerial phe~o~ena may be round in Gale's Encyclopedia of Associations
(Editio~ 9, Vol !, pp. U32-3). Such timely review of the situation
ry ~rivst~ g~oups i~s~res that sound evidence will not be overlooked
