Project 10073 Record Card — Killeen, Texas, 17 September 1952

This document consists of a series of military communications regarding a sighting of an unidentified aerial phenomenon reported by Corporal Harold M. Blair of the Military Police Company, 8456th AAU, at Killeen Base, Texas. On 17 September 1952, at approximately 0438 hours, while on guard duty at Post 33, Corporal Blair observed an object flying overhead. He described the object as a 'flying saucer type' approximately 10 feet in diameter, exhibiting a green fluorescent appearance with two red flames protruding from the rear. The object was observed for two to three seconds at an estimated altitude of 1000 feet, traveling from the Southwest to the Northeast at a speed estimated between 700 and 800 miles per hour. Blair reported hearing a sound similar to a model airplane engine approximately two seconds after the sighting. The report includes a sketch made by Blair depicting the object. The investigating officer, Philip Bader of the 901st CIC Detachment, noted in the official record that the source did not sound credible. The report was forwarded through military channels, including the Headquarters Fourth Army and the Office of the AC of S, G2, to the Air Materiel Command at Wright-Patterson Air Force Base for further information. The documentation includes the original Project 10073 record card, the agent report, and a cover letter from Colonel John P. Kaylor dated 6 October 1952.
