Documents / Report
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.

because the observer could not believe there are that many airplanes

are unes with which an effective investigator must be familiar.
It is obvious that not all liFO rc'ports are worthy of investigation.
What kinds of reports should be investigated? Persons who have
leng L.y experience I"ork i ng wi th UFO reports give varying answers
to this question. NICAP discards unsuhstantiated tales of rides
in flying saucers, on tho basis that their investigators have found
no evidence to support these claims but have found considerable
evidence of' fraud (NICi\P 19 ( 4). !\ir F")rec p 'actice is to neglect
reports of mere lights in the sky, particularly around air bases
or civil landing fields, for experie:lce has shown the UFOs in such
reports to ')e lights of aircraft or other COlJUTIOn lighteJ or reflecting
objects. Both Dr. J. Allen lIynek, scientific consultent to the Air
Force on UFOs, and Dr. Peter M, Mi llman (19G8), who is presently in
charge of the handling of UFO reports in Canada and has had an active
interest in UFO reports for nearly 20 years, have said they do ~ot
favor any field investigation of single-ob5erverdghtin~~sbecause
of the difficulty in deriving Hseful sclcntifi~~ information from
such reports.
