Project 10073 Record Card and Air Intelligence Information Report — Marietta, PA, 2 August 1952

On August 2, 1952, at approximately 02053 EDT (030053 Z), a civilian observer located one mile west of Marietta, Pennsylvania, reported sighting an unidentified flying object. The witness, a former radio operator for the USAAF during World War II with experience in aviation, described the object as a brilliant white light, approximately half the size of the moon. He observed the object appearing suddenly from the northwest, traveling in a straight line from west to east at a high rate of speed and a low altitude. The object produced no sound, exhaust, or trail, and vanished as suddenly as it had appeared. The total duration of the observation was estimated at two to three seconds. A second witness, located approximately one mile east of the primary observer, corroborated the sighting, describing a similar object, though she noted it appeared to be climbing at a 45-degree angle and believed it to be orange in color. The weather at the time was clear with 10-mile visibility. The reporting office, the Intelligence Office at Olmsted Air Force Base, concluded that they could offer no definite explanation for the sighting, noting that the reported facts seemed to rule out aircraft or astronomical phenomena. The primary witness expressed strong skepticism regarding the existence of such objects prior to his personal experience, explicitly stating that he did not believe the object was a man-made mechanical device, but rather a natural phenomenon currently unexplainable by science. The report was forwarded to the Air Technical Intelligence Center (ATIC) and the Directorate of Intelligence at Headquarters USAF.
