Project 10073 Record Card and Correspondence — Chicago, Illinois, August 1962

On August 21, 1962, at 0415Z, a sighting of an unidentified object occurred over Chicago, Illinois, near O'Hare International Airport. The primary witness, a 40-year-old housewife, reported observing a moon-like, flat, disc-shaped object that resembled a cup and saucer. The object was described as moving faster than a jet in a direct east-to-west flight path, eventually fading out to the west. The observation lasted approximately two minutes. In addition to the primary witness, four other individuals—two boys aged 15 and two women aged 31—also observed the object. The weather conditions at the time were reported as warm and clear with a few stars visible. Thomas A. Hilquist, Base Operations Officer for the 64th Troop Carrier Squadron, formally reported the incident to the Air Technical Intelligence Center at Wright-Patterson Air Force Base on August 24, 1962, in accordance with AFR 200-2. The official conclusion recorded on the Project 10073 record card suggests that the flight characteristics were consistent with an aircraft observation, but due to limited data, the case was ultimately classified as having insufficient data for a definitive evaluation.
