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

This document contains two Project 10073 record cards and associated correspondence from the 64th Troop Carrier Squadron regarding unidentified flying objects reported over Chicago, Illinois, in October 1962. The first incident, occurring on 10 October 1962, involved a witness observing an illuminated object with the appearance of a star moving from west to east for approximately 15 minutes. The witness used low-power binoculars and suspected the object might be a satellite. Air Force evaluation concluded the object was the ECHO I satellite, noting that while data was not immediately available for Chicago, the satellite's trajectory over Toronto shortly after the sighting made it likely visible from Chicago. The second incident, reported on 18 October 1962, involved two boys, aged 14 and 12, who observed a luminous, cigar-shaped object moving from east to west below the height of two jets. The observation lasted 23 seconds, and the altitude could not be determined. The official conclusion for this second case was that there was insufficient data for a definitive evaluation.
