Report of Investigation: Unidentified Aerial Object, Ritchie Highway, Baltimore, Maryland, 29 March 1952

This report details an investigation by the Office of Special Investigations (OSI) into a reported sighting of an unidentified aerial object on 29 March 1952, near Ritchie Highway in Baltimore, Maryland. The primary witness, Donald F. Stewart, claimed that while driving with a passenger, George S. Tyler III, a disk-like, luminous silver object hovered 200 feet above their vehicle. Stewart alleged that the object caused his car engine to stop, cracked the paint, and magnetized the wiring. He described the object as having a dome and neon-like lights. The investigation was initiated after the report was relayed to the Air Technical Intelligence Center by Ulius Louis Amoss, who had received the information from a local radio announcer, Lou Corbin. OSI agents conducted a thorough investigation, interviewing Stewart, Tyler, and various local experts. An engineer from Westinghouse, Raymond Fox, examined Stewart's vehicle and found no unusual defects or evidence of magnetization. Furthermore, an inspection of the car revealed it had been recently painted, casting doubt on Stewart's claim regarding the paint cracking. When re-interviewed, the passenger, George S. Tyler III, admitted that he had not been present during the alleged sighting and that Stewart had asked him to corroborate the story. Local police and the FBI field office in Baltimore reported no other sightings or records of such an incident in the area. The investigation concluded that the sighting was likely a fabrication by Stewart.
