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.

At about O?OO EST Washington Center advised that their radar had a target five miles east of Andrews Field. Andrews tower reported seeing a light, which changed color, and said it was moving towards Andrews. T went outside as no target appeared on Andrews radar and 3aw a light as re- ported by the tower. It was between 10° and 15° above the hori wn and seemed to change color, from red to orange to green to red again. Jt seemed to float, hut at times to dip suddenly and appear to lose altitude" It did not have thf 'pearance uf any star J have rver observed before. , time of observation there wa~ a star due east of my ~Jsition. Its brilliance was approximately the same as the object and it appeared at about the same angle, 10° to ISO above the hor j zan. 'I11e s tar did not change color or have any a~parent movement. I estimated the object to be between thrPA and four miles east of Andrews Field at approximately 2,000 ft. During the next hour very few reports were re- cei ved from Washington Center. [According to Washington Center's account, however, the C20n EST object was seen on radar to pass over Andrews and fade out to the southwest of Andrews -- (~. D. T.] At approximately ()jOO EST I again went outside to look at the object. At this time both the star and the object llad increased elevation by about l()o. [The azimuth would have also increased about 10" J 50 that the observed change was apparent ly equal to tlw sidereal rate, ISO of right ascension per hour -- (~. D. T.] "111C object h.ld ccasel\ tD have allY apparent movement, hut still appeared to he changing ('olor. On the hasis cf the second ohser~ation, 1 believe th0 unidentified object was a star.
