Project 10073 Record — Sighting of 5 September 1965

This document is a collection of records and incoming messages regarding a sighting on 5 September 1965, involving a large fireball observed across the northern United States and Canada, specifically in Minnesota, Michigan, and Ontario. Multiple witnesses, including civilians, state police, and military personnel, reported seeing a bright, circular object with a vapor trail moving from west to east. The object was described as greenish-orange or blue with a red tail, and it reportedly exploded into two pieces before appearing to crash into Lake Superior. The duration of the observation was consistently reported as 4 to 5 seconds. A loud 'boom' sound was associated with the event. Official records from the Air Force, specifically under Project 10073, categorize the event as a 'Fireball Class' object, with the official conclusion being a meteor. Despite the investigation, no physical evidence was recovered, and no radar contact was confirmed. The weather conditions at the time were reported as clear with a strong inversion layer. The reports were processed by the Foreign Technology Division and delivered to the Defense Intelligence Agency.
