Summary
On May 10, 1956, a prisoner at Waupun, Wisconsin, reported one object. The report was filed under Project 10073, the Air Force's official record for unidentified flying object reports. This was a later report from the same observer.
The witness said the object was round and about the size of a baseball at arm's length. It was red and followed a smooth, even flight path. At first it was believed to be an aircraft. The sighting lasted about two minutes.
The Air Force concluded the sighting was possibly caused by the exhaust of a jet aircraft. The record cited the even flight path, the duration, and the color.
