Project 10073 Record Cards and Correspondence — Chicago, Illinois, September 1962

This document contains a series of Project 10073 record cards and official correspondence from the 64th Troop Carrier Squadron (Reserve) at O'Hare International Airport, Chicago, regarding two separate Unidentified Flying Object sightings in September 1962. The first incident occurred on September 12, 1962, involving a civilian witness who observed an object described as a round sphere or blimp-like shape with blinking lights across its middle. The witness, who was on a porch in Chicago, reported that the object rotated from right to left and moved from the western horizon toward the east over a duration of approximately two and a half minutes. The witness noted that the object was about the size of a half-dollar held at arm's length and explicitly stated it was not a helicopter, balloon, or airplane. A second report details a sighting on September 27, 1962, involving a bright, round object with rays moving slowly to the northeast. Official Air Force documentation for both cases, signed by Base Operations Officer Thomas A. Hilquist, concludes that there was insufficient data for a formal analysis, citing a lack of essential flight pattern and positional information. The records include standard Project 10073 record cards, formal letters to the Foreign Technology Division at Wright-Patterson AFB, and a personal letter from a witness describing their observation in detail.
