Project 10073 Record Card and Air Intelligence Information Report — Palmyra, Pennsylvania, 24 August 1952

This document consists of a Project 10073 record card and an Air Intelligence Information Report regarding a UFO sighting that occurred on 24 August 1952, near Campbellstown, Pennsylvania. The report was prepared by 2d Lt. John L. Spiegel of the Intelligence Office at Olmsted Air Force Base. A civilian witness, employed as a signal maintainer for the Reading Railroad, reported observing a 'very bright' light to the left of his home at approximately 2150Z. The witness stated that the object remained in a stationary position for approximately five minutes before disappearing. During this time, the light reportedly blinked on and off. The witness also noted that an airplane was flying in the vicinity of the local airport and that while there were occasional reflections from the aircraft, the unidentified object did not resemble these reflections. Three other members of the witness's family also observed the light. The intelligence report notes that the weather at the time was clear with 15 miles of visibility and winds from the northwest at 8 knots. The investigating officer concluded that there was no definite explanation for the sighting. While the duration of the observation seemed to discount the possibility of an aircraft, the report suggests that a weather balloon remained a strong possibility. The document includes standard project worksheets and weather data sheets used by the Air Technical Intelligence Center (ATIC) for evaluating such reports.
