Project 10073 Record — Monroe, Michigan, 21 June 1949

On 21 June 1949, at approximately 9:24 a.m., a civilian witness in Monroe, Michigan, reported observing a flying object directly overhead. The witness described the object as having a disc-like top and a heavy center section. The object was seen traveling among several Naval aircraft in a southwest direction and remained in view for only two seconds. A notable feature reported by the witness was a vapor disturbance that appeared to be whorling from the outer edge of the object as it moved. The sighting was subsequently reported to the Navy, and a similar account was received via telephone from Almon Jones, a reporter for the Monroe Evening News, on 23 June 1949. Captain J. P. Walker of the Navy forwarded the report to the Chief of Naval Operations on 29 June 1949. The official conclusion recorded for the incident under Project 10073 was that there was insufficient data to identify the object, though the initial report speculated that it might have been a new type of ram jet machine.
