Project 10073 Record Card — Arlington Heights, Illinois, 25 September 1962

This document consists of a Project 10073 record card and associated Air Force message traffic regarding a UFO sighting in Arlington Heights, Illinois, on 25 September 1962. The report details a sighting by four military personnel, including SP/4 Hohn Navarre, PVT Robert J. Saviterri, PVT Rovert L. Roeder, and SP/4 John G. Hosteltler. The witnesses described a 200-300 foot diameter saucer-shaped object with 20 evenly spaced windows, excluding a gap of two spaces. The object was observed at an altitude of 1500 feet for approximately 3-4 minutes. It was reported to have circled, hovered, and emitted a whining sound similar to a jet engine. The object's color reportedly shifted from a white light to a red-orange. The witnesses observed the object from a residential area. Official Air Force conclusions initially categorized the case as 'UNIDENTIFIED,' noting that while it resembled an aircraft with advertising lights, no such plane was confirmed in the area at the time. The document also includes a questionnaire completed by a witness in August 1963, which provides additional narrative details, including the witness's perception that the object was 'vapor-like' and caused a reaction in the surrounding environment, specifically describing the moon appearing as an 'ornate cross' during the event. The file includes internal Air Force message traffic (AF IN 19659) and notes referencing J. Allen Hynek.
