Project 10073 Record Card — Minot, North Dakota, 27 October 1957

This document consists of a Project 10073 record card and associated teletype reports regarding an unidentified aerial phenomenon observed on 27 October 1957 in Minot, North Dakota. Two witnesses, identified as schoolboys aged 14 and 16, reported observing a round, white object, described as being the size of a half-dollar, traveling at a very high speed from the southwest to the northeast. The witnesses noted that the object possessed a very bright light and was at a high altitude. Additionally, they reported hearing a low hum on an amplifier while the object was in sight. The observation lasted approximately two minutes under clear weather conditions with some clouds in the west. The official evaluation by the Air Technical Intelligence Center (ATIC) concluded that the characteristics of the sighting were consistent with an aircraft observed at a very high altitude, and that the reported audio hum was a misinterpretation. However, internal notes from the reporting officer suggest that the object might have been a Russian earth satellite, though attempts to verify this against satellite timetables were unsuccessful, leaving the final cause of the sighting officially listed as unknown in the teletype report.
