Project 10073 Record Card — Detroit, Michigan, 7 August 1952

This document contains a collection of reports and correspondence regarding an unidentified aerial object sighting in Detroit, Michigan, on 7 August 1952. The primary witness, a 50-year-old crane operator, reported observing a light that appeared to be the size of a large star, white in color, which changed intermittently to red. The witness stated that the object remained motionless for 15 to 20 minutes before moving out of sight. The witness's wife also observed the object. The report includes a detailed observer questionnaire where the witness describes the object as solid, noting that it would 'jump up and down' and turn to one side, emitting a reddish glow. The witness explicitly stated they had 'no idea' what the object was. Official military documentation from the 575th Air Base Group at Selfridge Air Force Base confirms the report was filed in compliance with AFR 200-5. The investigation by Major Joseph P. Kelsey noted that the object was observed visually from the ground and that two jets were in the area at the time of the sighting, though no other aircraft were known to be present. The weather was reported as clear with fifteen-mile visibility. The file also contains administrative correspondence between the Air Technical Intelligence Center and the Weather Bureau regarding balloon launches in the area, suggesting an attempt to correlate the sighting with meteorological activities. The case was processed under Project 10073 and referenced as part of Project Blue Book.
