Project 10073 Record Card and Incoming Message — 17 August 1958 Sighting, Warren, Michigan

This document consists of a Project 10073 record card and a series of incoming Air Force messages detailing a UFO sighting that occurred on 17 August 1958 in Warren, Michigan. The primary witness, a civilian whose name is redacted, observed the object using 8x30 military-type Japanese field glasses. The witness described the object as initially ball-shaped and white, later appearing as a saucer-shaped, gray-white object with a centered circular component and an encircling ring. The object remained motionless for approximately seven to eight minutes before moving north-northeast, rotating, and then speeding toward the west-southwest, where it vanished. The witness estimated the object's size at 60 feet in diameter and its altitude between 200 and 500 miles. During the observation, four aircraft were noted flying north at a much lower altitude of approximately two and a half miles. The report notes that there was no visible exhaust or propulsion mechanism. The weather was described as cloudless with good visibility. Official Air Force records categorized the sighting as 'Unidentified.' Handwritten notes on the document reflect skepticism from military personnel regarding the witness's ability to discern such specific structural details on an object that appeared so small to the naked eye, specifically noting the contradiction of describing a 'pea-sized' object with such complex features. The report confirms that no physical evidence or photographs were obtained.
