Project 10073 Record Card — Detroit, Michigan, 17 August 1958

This document contains a Project 10073 record card and associated military correspondence regarding an Unidentified Flying Object (UFO) sighting in Detroit, Michigan, on August 17, 1958. The sighting was reported by a civilian witness at 0245Z. The witness described a single, round, bluish-white object, approximately the diameter of a pencil, which exhibited a blinking pattern at a rate of once per second. The object was observed to have a halo twice its size and traveled on a straight path toward the south for a duration of ten minutes. The observation was made via ground-visual means with no optical aids. Weather conditions at the time were reported as clear with 15 miles of visibility. The military investigation, conducted by the 661st ACWRON and processed through the Air Technical Intelligence Center (ATIC), concluded that the object was likely an aircraft, possibly with a broken or missing tail light lens. The documentation includes a teletype message (TWX) from the 661st ACWRON to various Air Force commands, including the Air Defense Command and the Air Technical Intelligence Center. This message was originally classified as Secret but was subsequently downgraded to Unclassified, with a note indicating that the initial classification was an error and that the report had not been properly assigned a number. The file also contains a formal record card summarizing the incident details, including the conclusion that there was no physical evidence and that the sighting was likely an aircraft.
