Air Intelligence Information Report — Sighting at 200 Linda Drive, San Antonio, Texas, 16 July 1952

This document is an Air Intelligence Information Report (AF Form 112) regarding an unidentified aerial phenomenon observed on 16 July 1952 in San Antonio, Texas. The report was filed by Major Robert W. Fox of the San Antonio Air Materiel Area on 24 July 1952. The primary witnesses were a civilian woman and her daughter, who observed the object from their residence at 200 Linda Drive. According to the witnesses, the object was first sighted at 0915 hours. It appeared as a brilliant, whitish, silver, disc-shaped object of immense size, estimated to be much higher than 40,000 feet. The witnesses reported that the object approached from the south, moved north, and then hovered for approximately one hour and twenty minutes. During the observation, the object performed flipping maneuvers, revealing an oblong shape, and shifted its position. A notable feature described by the witnesses was a pendulum-like apparatus fixed to the underside of the object, which appeared to have two bulb-like knobs attached. These knobs emitted flashes of light described as 'balls of fire' or 'terrific brilliance,' similar to burning magnesium. The witnesses observed the object with the naked eye and with 7x40 Carl Zeiss-Jena binoculars. They noted that the object was metallic in construction and that no sound was heard. The weather conditions were described as fair, with clear skies and no wind. The object eventually disappeared by moving upward until it was no longer visible. The report includes a detailed questionnaire completed by the primary witness, which provides further context regarding the sighting, including the witness's background and their inability to provide a conventional explanation for the object. The report was forwarded to the Air Technical Intelligence Center (ATIC) for further evaluation. The document also contains a teletype message (CITE SA-396) summarizing the incident, which confirms the details provided in the formal report. The witnesses were confident in their observations, and the report notes that there was no meteorological explanation for the sighting and no interception or identification action was taken by military authorities.
