Book was one of a series of systematic studies of Unidentified flying objects
(UFOs) conducted by the United States Air Force (U.S.A.F.). Started in 1952, it
was the second revival of such a study. A termination order was given for the
study in December 1969, and all activity under its auspices ceased in January

Pages, 3MB] – It is unclear if this document is part of the Blue Book system.
It does confirm, however, that towards the end of the Blue Book era, military
installations were still seeing UFOs – some they were later able to identify –
while others they were not.

Review of the
University of Colorado Report on Unidentified Flying Objects by a Panel of the
National Academy of Sciences – The ad hoc committee concurs with the
findings of the report of the University of Colorado entitled ‘Scientific Study
of Unidentified Flying Objects,’ Dr. Edward U. Condon, Scientific Director.
Panel agrees that a study of UFOs in general is not a promising way to expand
scientific understanding of the phenomena, and adds: ‘On the basis of present
knowledge the least likely explanation of UFOs is the hypothesis of
extraterrestrial visitations by intelligent beings.’
