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.

nt 50,000 ft. and no"/:;:) knots at SS,()()() ft. the plotted track of the UFO is consistent with the obser'Jcd upper winds. 'Ine hEp \\'3.5 first "painted" at a 24l)° azimuth, which may explain where that quantity originated in the UFO movement report. Conclusion: almost certajnly a weather balloon. Note that the \\'inds reported fOT the I~Tight-Patterson AFB 1000 LST show winds blowing first from the east, then from the SSE, ultimaleLy from the west at higher altitudes. These winds were bloWing in such a manner that it is conc'::!ivable that Wright-Patterson's own radiosonde halloon may have been the UFO in this incident. 76-B. Near Charleston, W. Va., 4 May 1966, 0340 LST. Weather: Severe thunderstorms in area. Pi10t of a Braniff Airlines Boeing 707 flying at 33, 000 ft. observed on his left side what appeared to be a fas t- flying aircraft with landing lights. Braniff's ai rbornl'; radar recorded this unknown. Pilot requested the radar operator at Charleston sector of Indianapolis ARTC to look for traffic at his 8:30 or 9:00 position, and the radar picked up a track in this position. Return made a sweeping turn and disappeared off scope to the southwest. t<.r: American Air lines pi lot flying 20 m~i. behind the Brani ff plane saw the object. It appeared to him to be a normal ai reraft with land- ing lights. TIlis pilot stated he had often seen such aircraft with lights during AF refueling missions. Estimated speed of the unknown was 750-800 mph. No unusual maneuvers were performed or any th"t were beyond known military aircraft capabilities at the time. AF explanation ic; that the unknown was an aircraft wi til lanJing lights on. '111j s is consistent wi th the reported facts. Case 2.
