Project 10073 Record: Incident #396 - Ginger Hill, Pennsylvania

This document is a formal Report of Investigation conducted by the Office of Special Investigations (OSI) regarding a sighting of an unidentified aerial phenomenon on June 4, 1949. The primary witness, a Chief Engineer for the Pittsburgh Coal Washer Co., reported observing an oval, highly polished, and very thin object while driving on Old Brownsville Road, approximately 1.5 miles southeast of Ginger Hill, Pennsylvania. The witness, who was accompanied by his brother, estimated the object's altitude at 4,000 feet and noted it was traveling at approximately twice the speed of a conventional aircraft. The object maintained a straight and level flight path from northwest to southeast, tilted at a 45-degree angle, and made no sound. It lacked any visible projections, lights, exhaust, or vaporization. The witness observed the object for approximately 30 seconds before it disappeared behind trees. The witness's brother, who was a passenger in the vehicle, did not see the object. The investigation included interviews with the witness and his employer, as well as checks with the Greater Pittsburgh Airport, Allegheny County Municipal Airport, and the U.S. Weather Bureau. These checks confirmed that no aircraft were reported in the vicinity at the time of the sighting and that no weather balloons were aloft. Despite the lack of corroborating reports, the official conclusion recorded in the project file is 'AIRCRAFT'. The report highlights the witness's professional background in engineering and drafting as a basis for his ability to accurately judge speed, distance, and color. The document is part of the Project Grudge series and was processed under file number 24-23.
