Project 10073 Record Card and Related Correspondence — Cleveland, Ohio, November 1957

On November 7, 1957, at approximately 0010Z, a civilian observer in Cleveland, Ohio, reported sighting a round, blue-green object, described as being the size of a basketball. The object was observed for five minutes moving in a counter-clockwise motion. The report was processed under Project 10073 and assigned the reference number INT 11-222. The 662nd Aircraft Control and Warning Squadron (ACWRON) investigated the incident, noting that the observer was not experienced. Military personnel, including 1st Lt. William R. Schreiner, evaluated the report alongside weather data from Youngstown, Ohio, which indicated scattered cloud formations in the area. The military investigation concluded that the object was likely a reflection of searchlights from the city of Cleveland against the scattered clouds. This conclusion was supported by the fact that searchlights were active in the area at the time, and similar reports had been received previously. The official assessment, documented in both a record card and a joint message form, categorized the sighting as a probable reflection rather than an unidentified aerial phenomenon of unknown origin.
