Project 10073 Record Card — Sault Ste Marie, Michigan, 11 Dec 60

This document is a Project 10073 record card and accompanying report regarding a sighting of an unidentified aerial phenomenon near Sault Ste Marie, Michigan, on December 11, 1960. At 2030Z, a civilian witness, whose name is illegible in the report, observed a bright orange light in the sky. The witness reported that the light was followed by the sound of an explosion, after which a white object was observed falling to the ground. The sighting was reported to the Detroit Flight Service Center and subsequently relayed to Captain Bainbridge P. Steele of the 2046th AACS at Wright-Patterson Air Force Base. Captain Steele then contacted the Aerospace Technical Intelligence Center (ATIC). An auxiliary policeman, also unnamed in the document, was mentioned in connection with the report. Following the initial notification, a check of Flight Service records was conducted, which confirmed that there were no military or civilian aircraft, either US or Canadian, that were lost, missing, or overdue at the time of the incident. Due to the nature of the report, it was determined that the standard Air Force UFO Questionnaire (Form 146) was not feasible for this case. The final conclusion recorded on the project card, signed by Captain Bruno A. Mininni, suggests that the object was likely a bolide, noting that the witness provided limited information, but the details provided were consistent with such a phenomenon.
