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.
