Project 10073 Record Card — La Mesa, California, 13 June 1956

This document consists of a Project 10073 record card and a supporting teletype message regarding an unidentified aerial phenomenon reported on June 13, 1956, in La Mesa, California. A civilian witness reported observing a single, oval-shaped, incandescent object, described as being the size of a basketball. The object was sighted at an altitude estimated between 1,000 and 2,000 feet, moving in a southeasterly direction. The observation lasted for approximately three to four minutes, during which the object appeared to be circling in the area near a destroyer base in San Diego. The report was filed by 1st Lt. Robert L. Larrowe of the 751st AC&W Squadron. Military authorities investigated the possibility that the object was a burning aircraft, but they were unable to uncover any reports of emergencies in the area. The final conclusion recorded on the document is that the event was a 'probable a/c sighting' (aircraft sighting). The teletype message provides additional technical details, including weather conditions, which were noted as clear with unlimited visibility, and confirms that the sighting occurred at night. The document serves as a standard military record of a UAP report processed through the Air Technical Intelligence Center channels.
