Project 10073 Record Card — Martic Forge, PA, 9 September 1952

On September 9, 1952, at 2347 hours, a civilian couple in Martic Forge, Pennsylvania, observed an unidentified flying object. The witnesses, who were outdoors at the time, described the object as a bright white light moving at a high altitude on an ENE heading. They reported that the object did not appear to have a tail or other standard aircraft features, but noted it had a very large wing span. The observers heard a rumble that sounded like a jet aircraft for approximately 15 seconds. The weather conditions were clear with 15 miles of visibility. The witnesses, one of whom claimed to have some knowledge of aircraft, stated the object did not look like any aircraft they had previously seen. The report was filed by 2d Lt. John L. Spieral of the Intelligence Office at Olmsted Air Force Base. The official conclusion reached by the Air Technical Intelligence Center was that, despite the witnesses' claims, the object was likely an aircraft, specifically a jet.
