Project 10073 Record Card — Montebello, California, 1 December 1957

This document consists of a Project 10073 record card and a subsequent interview report dated 4 February 1958, concerning a UFO sighting in Montebello, California, on 1 December 1957. The initial report was triggered when a civilian's children observed six objects moving slowly westward. The witness captured motion pictures of the objects. However, the investigation revealed that the film only showed two objects moving in unison, rather than the six claimed by the witness. The investigating officer, Captain Richard G. Schaller, noted that the case was handled poorly by the Public Relations Office (OIS) in Hollywood, which prioritized publicity over proper intelligence procedures. The witness was described as having an antagonistic attitude toward the Air Force. During the interview, the witness estimated the objects were at an altitude of 3000 to 4000 feet, similar to light aircraft, but denied they were as high as jet aircraft. He described the objects as circular, flat, and glowing with a white-blue-green light. He explicitly stated they were not balloons or airplanes he had seen before. The official conclusion of the Air Force analysis was that the objects were a balloon test rig used for variable and wind tests. The document also notes that the witness was in the process of moving to Redding, California, at the time of the interview.
