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.
As for the radar "track", a blip appearing for only "n few sweeps" could be almost anything: noise, AP, or ro~sihly n real target flying near the lower limits of the radar beam. 1212-8. Tillamook, Orc., U-14 March 1%7, 2230-0n08 LST. Weather: clear with "stars plainly visible," some grounJ fog, thin hroken cirriform clouds estimated at 10,000 ft., visihility 15 mi. This 1.8 a good example of some of the confusion that arises in reporting UHi incidents. rni tial visual observer reports indicated object at ahClut 45 0 to 50° elevation angle, yet whcn the Mt, \lebo radar station "',>n- tacted target" it was at 39 mi. range, ~1,2D[) ft. heir-ht.
