Air Intelligence Information Report — San Antonio, Texas, July 1952

This document is an Air Intelligence Information Report (AF Form 112) issued by the Headquarters of the San Antonio Air Materiel Area at Kelly Air Force Base, Texas, on July 18, 1952. The report details a sighting of an unidentified aerial phenomenon reported by a civilian employee, Mrs. Alice Dieter, who worked at Kelly Air Force Base. According to the report, the incident occurred between 2300 hours on July 15, 1952, and 0200 hours on July 16, 1952. The witness observed a single, cigar-shaped object at her residence on Wild Rose Drive in San Antonio. The object was described as emitting a green, phosphorescent light and was estimated to be approximately three by six feet in size. It was seen flying at a low altitude, estimated between 150 and 200 feet, moving across the Southeast sky toward the West. The witness reported that the object traveled at a tremendous rate of speed, faster than any conventional aircraft she had seen, and disappeared rapidly. The duration of the sighting was estimated to be between three and five seconds. The report notes that the object made no sound and displayed no visible aerodynamic features, such as exhaust or trails. The weather conditions at the time were described as fair. The investigating officer, Major Robert W. Fox, noted that there was no physical evidence of the sighting, no interception or identification action was taken, and there was no apparent logical explanation for the event. The document also includes a separate, brief report regarding a different sighting of seven lighted objects in a V-formation, which was also investigated by the same office. The report was submitted in compliance with Air Force Letter 200-5, dated April 29, 1952, and was forwarded to the Air Technical Intelligence Center at Wright-Patterson Air Force Base for further review.
