Project 10073 Record Card and UFO Report — Detroit, Michigan, 15 April 1959

This document consists of a Project 10073 record card and a formal teletype report regarding a UFO sighting that occurred on April 15, 1959, in Detroit, Michigan. The witness, a civilian identified as a chemist and engineer, reported observing a single, disc-shaped, bluish-white object, described as being the size of a pea. The object was first spotted near the position of the moon and was last seen near the position of Saturn before it disappeared instantly. The duration of the sighting was estimated at three to five seconds. The observer, who was engaged in amateur astrology at the time, explicitly stated his belief that the object was not a comet or any other known astronomical phenomenon. The report was filed by the 661 ACWRON and addressed to the Air Defense Command (ADC) and other intelligence units, in accordance with Air Force Regulation 200-2. Senior Director 2/LT George J. Rollman reviewed the report and noted that the witness appeared to be a reliable source. Despite the witness's skepticism regarding astronomical explanations, the official conclusion recorded on the Project 10073 card is that the most probable cause of the sighting was a meteor. The report confirms that there were no photographs, physical evidence, or radar contacts associated with the event, and weather conditions were reported as clear with no clouds.
