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.
letter refers to the origin of the case: B-number cases are from USAF Project Blue Book files, N-numbers are for casE'S supplied by NICAP (National Invest.i:;ations Commi ttee for Aerial Phene-mena), C-numbers refer to cases that were investigated by pers~nnel of the Colorado project. and X-nun,bers were given to cases that were received after the wt-off date for inclusion iT' the regular files (i.e., after the computer analysis of all project file cases had already been compb~ted). X-number cases are also identified hy their B-, N-, or C- number. Class I-A: Primarily visual, star-like cases. 1321-B. This is a good example of a misidentified star combined with an apparen~: ly uncorrelated radar r~turn causing an UFO report to he generated. The incident took place at Finland Air Force Base (60 mi. NE of Duluth), !\linn., with a civili1.n sighting near Grand Marais, Minn., (SO mi. NE of Finland AFB) on the night of 5-6 September 1966, between 2130 and 0015 LST (0330-0615 G~1T). The weather was clear, ceiling unlimited, visibility more than 15 mi.; a display of Aurora Borealis was in progress. Applicable radio refractivity profile is shown in Fig. 1 . Visual reports of a "whi te-red-green" ohj eet "moving but not leaving its general location" were received at Finland AFR about 2130 LST. An FPS-90 search radar was activated but there was '~Oo much clutter to Sf'€' anything in that area ... " At ?LOO LST a re- turn was detected; it "flitted around in range from 13 to S4 mi., but always stayed on the 270° azimuth." A pair 0f F-89s was scrambled from Duluth AFB and searched the area at altitudes of 8,000 - 10,000 ft. The two aircraft "merged with blip, apparently wrong altitude, no airborne sighting"; the radar operators insisted the target was at 8,000 - 10,000 ft., the same altitude at which the scrambled aircraft were flying. The pilots reported that they "only observed what was interpreted to be a beacon reflection." Available meteorological data show that the winds were south- westerly, 7 knots at the surface, and northerly (320° to 30°) at 178 letter refers to the origin of the case: B-numbcr case~ are from USAF Project Blue Book files, N-number~ are for cases supplied by NICAP (National Investi:;€ltions Commi ttee for Aerial Phcn0mcna), C-numbers refer to cases that were investigated by pers~nnel of the Colorado project, and X-null,bers were given to cases that were received after the (;ut-off date for inclusion ir the regular files (i.e., after th~ computer analysis of all project file cases had already been compl.~ted).
