A civilian reported three silver, round objects over Penbrook, PA, on August 17, 1952. Air Force investigators concluded the objects were likely aircraft, citing the presence of Air National Guard planes and the witness's report of engine-like sounds.
This document comprises an Air Intelligence Information Report and associated Project 10073 record cards regarding a sighting of three unidentified flying objects over Penbrook, Pennsylvania, on August 17, 1952. The primary witness, a civilian, reported observing three silver, round, thin objects, roughly the size of a football, drifting at an altitude estimated between 10 and 250 feet before accelerating to the speed of an airplane. The witness reported hearing a sound similar to a distant aircraft. The investigation, conducted by 2d Lt. John L. Spiegel of the Intelligence Office at Olmsted Air Force Base, determined that the objects were in all probability aircraft. This conclusion was supported by the presence of Air National Guard fighter aircraft in the vicinity during the time of the observation and the witness's own admission of hearing distant airplane noises. The investigator further noted that while the witness believed the objects were very low, their disappearance behind clouds at 5,000 feet indicated they were likely much larger and at a greater distance than the observer perceived. The report was classified as unclassified and distributed to the Air Technical Intelligence Center (ATIC) and Air Force headquarters.
Other comments by the observer and his wife, who also witnessed the sighting, very strongly indicate that the objects were aircraft.
