Project 10073 Record Card — Sighting of May 13, 1952, National City, California

This document is a Spot Intelligence Report dated July 11, 1952, issued by the 18th District Office of Special Investigations regarding findings of unconventional airborne objects in the San Diego area between March and June 1952. The primary subject is an aeronautical engineer employed by the Consolidated-Vultee Aircraft Corporation who, along with other engineers, formed a 'Flying Saucer Sighting Club' to track and triangulate unidentified aerial phenomena. The report details a specific sighting on May 13, 1952, at 8:55 PM, where the witness observed a white, spherical object with an oscillating motion that emitted a red trail. The witness, using a 6-power telescope, estimated the object's altitude between 10,000 and 15,000 feet and noted that it moved at 150 to 250 miles per hour in horizontal flight, exhibiting no sound. The witness provided sketches and mathematical computations to the Air Force. Despite the witness's conviction that the object was a space ship under intelligent control, the official conclusion recorded on the Project 10073 record card is 'METEOR'. The report concludes that no further action is contemplated by the Air Force, though any additional reports received from the witness would be forwarded for evaluation. The document includes maps of the San Diego area and detailed personal accounts and diagrams provided by the witness.
