Project 10073 Record Card and UFO Report — Detroit, Michigan, September 1959

This document consists of a Project 10073 record card and a subsequent military teletype report regarding a UFO sighting in Detroit, Michigan, in September 1959. The witness, a maintenance worker at the Superior Products Concrete Pipe Co., reported observing an object crossing the face of the moon on three consecutive nights. The observation was made using a hand-made French telescope from 1716, which was approximately 42 inches long and 2.5 inches in diameter. The witness described the object as a dark, bullet-shaped silhouette with rectangular tail fins that protruded above and below the body. The object was estimated to be one-tenth the diameter of the moon and was visible for approximately two seconds each night as it moved from left to right. The report notes that there was no sound, no trail, and no exhaust associated with the object. Military authorities, specifically Capt. Joseph Strother of the ACWRON, hypothesized that the sighting was likely a result of increased public interest and scrutiny of the moon following a successful Soviet moon mission, suggesting that observers were more likely to notice objects crossing the lunar surface due to this heightened attention. The official conclusion recorded on the project card is that there was insufficient data to evaluate the sighting. No physical evidence, photographs, or radar contacts were associated with the event.
