Project 10073 Record Card and UFO Report — Sault Ste. Marie, Michigan, June 1959

This document comprises a series of military communications and a Project 10073 record card detailing an Unidentified Flying Object (UFO) sighting that occurred on June 19, 1959, near Sault Ste. Marie, Michigan. The primary witness, a Specialist 4 from the 68th Gun Battalion at Camp Lucas, reported observing a white, sphere-shaped object, approximately the size of a pea, moving in a straight line at an estimated altitude of 20,000 to 25,000 feet. The object was described as having a tail extending 50 to 100 miles behind it and emitting a whistling sound. The observation lasted between 20 and 30 seconds. The report was processed by the 753rd ACWRON at Sault Ste. Marie AFS and investigated by Lt. Lewis L. Libengood of the 661st ACWRON at Selfridge AFB. Following an investigation and analysis, the reporting officer concluded that the sighting was likely a reflection of light from the oxygen furnaces of the Algoma Steel Company, which had been reflected off a cloud of smoke. This conclusion was supported by the observation that similar phenomena had been reported in the same geographic area during the autumn of 1958. The document includes detailed weather data and coordinates for the observer's location, confirming the sighting occurred at night under clear conditions with scattered clouds at 1,200 feet. The report was submitted in accordance with Air Force Regulation (AFR) 200-2.
