Project 10073 Record Card and Air Intelligence Information Report — Bellefonte, Pennsylvania, September 1952

This document comprises a series of reports and a questionnaire regarding unidentified aerial phenomena observed near Olmsted Air Force Base in Middletown, Pennsylvania, in September 1952. The primary incident occurred on September 14, 1952, at approximately 0335 hours, when witnesses on duty at the West Gate of the base observed an object they described as resembling a large watermelon with a brilliant blue glow and six red lights. The witnesses reported that the object hovered, dropped, and then moved horizontally in a straight line before accelerating and disappearing behind trees in the mountains. They noted a humming sound similar to a distant motorboat, which persisted throughout the observation. The witnesses explicitly stated that the object was not a meteor or shooting star. A previous sighting was reported by the same individuals on the night of September 12, which also involved a sound similar to a motorboat. The official Air Intelligence Information Report, dated September 17, 1952, and authored by 2d Lt. John L. Spiegel, concludes that the sightings were likely misidentifications. The report suggests that the object observed on September 12 was a blimp, while the object seen on September 14 was likely an extremely bright star or a planet. The investigator acknowledges that these explanations are not 100% conclusive but deemed them sufficient at the time. The file includes a detailed observer questionnaire where the witness provides specific details about the sighting, including the object's appearance, behavior, and the environmental conditions, which were described as clear with two to three miles of visibility.
