Sighting Report — Detroit, Michigan, 10 June 1953

This document collection details the investigation of an unidentified aerial object sighting reported on 10 June 1953 in Detroit, Michigan. The primary witness, AFROTC Cadet Robert E. Alvey, observed a large, bright, white or light-yellow object at approximately 2310 EST. According to Alvey's statement, the object appeared in a high westerly position, moved in a falling arc toward the north, then leveled off and proceeded in a straight line at a high rate of speed before disappearing over the northern horizon. The observation lasted approximately 60 seconds. Alvey noted that the object was larger than a star, did not flicker, and produced no sound, trail, or exhaust.

The report was processed through AFROTC channels and forwarded to the Air Technical Intelligence Center (ATIC) at Wright-Patterson AFB. Official investigations included checks with local airports and the weather bureau to rule out conventional explanations such as aircraft or weather balloons. While a DC-4 aircraft was in the area, it was determined unlikely to be the source of the sighting. A weather balloon was also ruled out because it had burst prior to the time of the incident.

Correspondence between Dr. Allen Hynek of The Ohio State University and Lt. Robert Olsson of ATIC reveals ongoing internal debate regarding the nature of the object. While some initial assessments suggested a meteor, both Hynek and his assistant, Jennie, explicitly rejected this, arguing instead that the object was a 'landing light.' Despite these discussions, the official conclusion recorded in the report remained 'Unsolved.' The documentation includes the original Air Intelligence Information Report, a formal statement from Cadet Alvey, and internal correspondence regarding the status of various UFO cases under investigation by the Air Force at the time.
