Project 10073 Record — Sighting Report, Cleveland, Ohio, 4 September 1965

This document contains a Project Blue Book sighting report regarding an unidentified aerial phenomenon observed in Cleveland, Ohio, on September 4, 1965. The primary witness, a civilian, reported observing a large, dark metallic object for approximately 33 minutes. The witness described the object as appearing like two inverted saucers connected by rows of oblong windows, emitting brilliant red, green, and white lights. The object reportedly performed complex maneuvers, including hovering, jumping, and retracing its path, accompanied by a high-pitched sound. The witness attempted to contact Cleveland Hopkins International Airport and local radio stations during the event, but was told by airport personnel that no aircraft should be in the area due to a football game. The witness provided detailed sketches and narrative accounts of the object's appearance and behavior. An internal evaluation by Major Hector Quintanilla, Jr., concluded that the object was likely an advertising aircraft, despite the witness's detailed description of the object's flight path and maneuvers, which the evaluator noted did not fully support the advertising plane hypothesis. The file includes correspondence, completed questionnaires, and hand-drawn sketches by the witness and their son.
