Project 10073 Record Card — San Antonio, Texas, 7 August 1952

This document is an Air Intelligence Information Report concerning a sighting of four unidentified aerial objects over San Antonio, Texas, on 7 August 1952. The report, dated 12 August 1952, was prepared by Major Robert W. Fox of the San Antonio Air Materiel Area. According to the witness statement, the observer and her mother witnessed four objects that appeared to be approximately 18 inches in diameter, round but flat, and resembling metal heated to a white heat. The objects were observed over a period of approximately 70 minutes. The witness described the objects as performing erratic maneuvers, including U-turns, large circles, and rapid changes in direction, with one object moving at speeds estimated to be three times faster than a propeller-driven aircraft. No sound, exhaust, or aerodynamic features were noted. One object was observed to disappear by vanishing suddenly, similar to an extinguished light. A two-engined aircraft was noted to pass under the fourth object without any apparent reaction. The official conclusion recorded on the Project 10073 record card is 'Insufficient Data for Evaluation,' and the investigator's comment characterizes the report as 'rather sketchy.' The documentation includes the formal Air Intelligence Information Report (AF Form 112), a witness statement, and a teletype summary of the incident.
