AIR INTELLIGENCE INFORMATION REPORT - Unidentified Flying Object - Fifteen miles north of Goodland, Kansas

On April 29, 1952, at approximately 2200 CST, a B-29 bombardier assigned to the 321st Bombardment Squadron, 90th Bombardment Wing M, reported an unidentified aerial phenomenon while flying 15 miles north of Goodland, Kansas. The witness, whose reliability and technical background were assessed as good, was in the bombardier's nose compartment at an altitude of 30,000 feet. He observed a white, fan-shaped light traveling rapidly in a westerly direction. The object was estimated to be 5,000 feet above the aircraft, with a base width of 50 feet and a trailing edge width of 100 to 150 feet. The light pulsated at a rate of 3 to 4 times per second and was visible for approximately 2 seconds before being obscured by the frame of the B-29. The witness reported no visible fuselage, no audible sound, and no radio interference. The Kansas City Air Traffic Control Center confirmed that no other air traffic was in the area at the time of the sighting. Subsequent investigations conducted by the Department of Astronomy at Washburn University in Topeka, Kansas, to determine if the object could be attributed to meteoric or other natural phenomena, yielded negative results. The report concludes that no physical evidence was found, and no interception or identification action was taken. The document includes sketches of the object and an annotated map of the area.
