Project Grudge Incident Report — Castleton, New York, 6 April 1949

This document is a formal Report of Investigation conducted by the United States Air Force Office of Special Investigations (OSI) regarding an alleged sighting of 'flying saucers' near Castleton, New York, on 6 April 1949. The investigation was initiated following a report in the Albany Times-Union on 7 April 1949, which described three objects flying in a 'C' formation. The primary witness, a school bus driver for Columbia Central High School, reported observing three shiny, silver, round objects, approximately 20 inches in diameter, spinning rapidly while flying in an easterly direction toward Boston. The witness estimated the objects were at the height of a thirty-five-story building and were spaced about 150 feet apart. He observed them for approximately one minute while driving his bus, noting that they appeared to disappear into or behind a cloud. The OSI investigation included checks with the FBI, the Albany Police Department, and the New York State Police, none of which yielded further information. Additionally, the investigation attempted to contact other potential witnesses in the Castleton and Ravena areas, but these efforts were unsuccessful. A check with the 648th Aircraft Control and Warning Squadron in Schenectady confirmed that their radar station was not in operation on the date of the incident. The report concludes that the investigation was closed with no further leads, as no other witnesses could be located to corroborate the account. The document includes various administrative records, including routing slips, correspondence between the Navy and the Air Force, and a standardized 'Guide to Investigation' form used to document the witness's observations.
