Project 10073 Record Card — Wall Lake, Michigan, 4 August 1956

This document consists of a Project 10073 record card and associated teletype correspondence regarding an Unidentified Aerial Phenomena (UAP) sighting that occurred on August 4, 1956, near Wall Lake, Michigan. The witness, an engineer with 24 hours of experience in the Ground Observer Corps (GOC), reported observing a single, round, orange object in the sky. The object was described as having a bright glow and being approximately the size of an orange held at arm's length. The observation lasted for two minutes, during which the witness used binoculars to track the object as it moved from West to Northwest before fading into the horizon. The report notes that the weather conditions were hazy at the time of the sighting. Official military evaluation of the incident, conducted by the Air Technical Intelligence Center at Wright-Patterson Air Force Base, concluded that the object was possibly an aircraft. The comments section of the record card explicitly suggests that the description of the bright glow in the sky indicated the possibility of a jet contrail. The report was processed in accordance with Air Force Regulation 200-2, which governed the reporting of UFOs at the time. The documentation includes technical details such as the time of the sighting (0453Z), the witness's background, and the lack of radar or photographic evidence.
