This is the final report of the Scientific Study of Unidentified Flying Objects, conducted by the University of Colorado under Air Force contract F44620-67-C-0035, with Edward U. Condon as scientific director and Daniel S. Gillmor as editor. It was submitted to the National Academy of Sciences on 15 November 1968 for review. The report includes field studies, photographic and radar analyses, case studies, historical chapters and appendices such as the Robertson Panel report and the Twining letter.
landing was directed to obs~l'Ve the object and he repli~'d that it looh:~
like a brilliant star. and he dismissed the sighting as such.
\~hen the controller at Shirai AFB was asked to look for target
an Gel.rada.r. he could find nothing for 15 min. He stated: "':"here were
thrE':e or four blips on low beamilUt none I could definitely get a move-
ment on or none I could get a reading on the RHI (range-height indicator)
scope." A nf'h controller taking over e, t 2345 LST "be lieved" he made
iada)~ contact wit,. the object 'lnd an F·-94 was scrambled. This offi.cer
stated: "The target \'las in a right orhit moving at varying speeds .. It
was impossible to estimate speed due to the short distances and times
involved." By the time the F-94 arrived in the area of the "bogie,"
Shiroi Gel had lost radar contact; regaining contact a.t \.)017 LST "on
a starboard orbit in the same area as before." The F-94 was vectored
in to the target. and at this point the timd:ng becomfls confused. The
Shirai controller states that the F-94 "reported contact at 0025 (LST)
and reported losi~\g contact at 0028 (LST)." The F-94 radar operator
states: "At 0016 (LS'l) r pic.ked up a 'cadar contal,:t at 100 port, 10°
below. at 6.00fJ yd. The target was rapidly moving from port to star-
board and a lock-on could not be accC'.mplished. A turn to the ~.'taTboard
was instigated [sic] to intercept target which disappeared on scope
in approximately 90 sec. No V1 sual contact \\a'.; made w1th the uniden-
tified target." Shiro~ Gel had lost the F-94 in ground clutter, and
had also lost the tr.rget. It is not clear wheth~:L' the Get radar ever
tracked the fast-moving target described by the F-94 crew. The maximum
range of the F··94's radar is not given in the Blue Book report.
The F-94 pilot stated that c.he weathf~r was very good with
"exceptional visibility of 60-70 miles." yet this fast-moving uro,
ob,iously far exceeding the F-94's air5peed (about 375 knots), was
seen by neither the aircraft crew nor the observers on the ground at
Shiroi Gel even though the UFO track cro~5ed over very close to
Shiroi Gel number four. There art:: many ol;}1er inconsistencies in the

The 11-94 pilot stated that che weather was very good with
"exceptional visibility of 60-70 miles," yet this fast-moving UFO,
obdously far exceeding the F-94's airspeed (about 375 knots), was
seen by neither the aircraft crew nor the observer5 on the ground at
Shiroi Gel even though the UFO track crossed over very close to
Shiroi Gel number four. There an many o~}1er inconsistencies in the
