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.
The file also carried a notation that Castle AFB was to £01'-
,-"ard to Blue Book information required in AFR 80-17, but this informa-
tion had not been received; therefore, the case was being carried
as "insufficient data." There waS no evidence of any follow-up
or further effort to get the information.
\VIlat were the UFO descriptions which did not, in the view of
investig::.ting offi cers. compal'~ with any bown aircraft activity
or capabi lity? The housewi fe's tll'scriptioll of what she and others
had seen, as recorded by the inteTviewhg officfrs, referred to
pulsating and glowing lights varying between shades of white, red
and green occasionally rt~ruainil\l~ stationary on a nearby ridge
and capable of moving in any diTl'ctll;n ::It greatly variab.e speeds,
generally exceeding tllat of jets ubserved in the area. In particUlar.
she once noted a vertical a~Cl'llt at a very rapid speed. On one
occasion, her husband was abll' to distillEuish a rcetangular-shaped
object with very bright lights at the U'fner'S.
The description contained other references to appearance and
motion. However, it is obviDU'- llwt, when taken literally and Idthout
allowance for common errors in prrception and cognition and without
allowance for subjective interpretations, the descriptions, as the
~'fficers stated, did not conform wi th ai reraft capabili tv. Failure
1o make 5uch allowance left til(' c. i gh tings unidentified.
