Project Grudge Incident Report 334 — Sidney, Ohio, 3 May 1949

This report details an investigation conducted by the United States Air Force Office of Special Investigations into a reported 'flying saucer' sighting in Sidney, Ohio, on 3 May 1949. The investigation was prompted by a request from Colonel W. R. Clingerman of the Air Materiel Command following a newspaper article published in the 7 May 1949 edition of the Dayton Daily News. Two primary witnesses were interviewed on 18 May 1949. The first witness, a jewelry store operator, reported observing a bright, shiny, disc-shaped object at approximately 0900 hours. He stated the object was approximately five inches in diameter, traveled at a fast rate of speed, and wavered in flight before climbing and descending slightly. He lost sight of the object when it was obstructed by a building. The second witness, a dairy deliveryman, reported seeing an oblong object, approximately the size of a softball, between 0900 and 0915 hours. He noted the object traveled north in a straight line and left a grayish-colored trail. Both witnesses reported the weather was clear with no wind and that no aircraft were in the vicinity. Neither witness took photographs of the object. The investigation concluded that the object was an aircraft. The report references a previous incident, Incident 310, for further context.
