Findings of Unconventional Airborne Objects, San Diego, California, March to June 1952

This document is a Spot Intelligence Report dated 11 July 1952, issued by the 18th District Office of Special Investigations of the United States Air Force. It concerns the activities of a group in San Diego, California, known as the 'Flying Saucer Sighting Club.' The club was founded by an aeronautical engineer employed by the Consolidated-Vultee Aircraft Corporation, along with other engineers. The group's methodology involved alerting members by telephone when an unidentified aerial object was sighted to facilitate tracking and triangulation. The report notes that the source provided various sketches and mathematical computations regarding sightings that occurred between March and June 1952. Specifically, the document references sightings on 2 March, 9 May, 13 May, 21 May, and 14 June 1952, all of which were described as 'meteor-like objects' observed at night. One specific incident report, dated 9 May 1952, describes a tubular object, 50 feet long and 20 feet in diameter, displaying blue, green, and orange lights. The object was reported as soundless, traveling at 200-300 MPH at an altitude of 1000-1500 feet, moving from west to east. The observer of this specific incident was a member of the aforementioned club. The Air Force concluded that these objects were astronomical in nature. The report concludes that no further action is contemplated by the Air Force regarding these specific findings, though any future reports received from the source would be forwarded for evaluation. The document includes an enclosure containing the reports and computations provided by the source for the Commanding General of the Air Materiel Command at Wright-Patterson Air Force Base.
