Project 10073 Record — Duluth, Minnesota, 18 August 1966

This document contains the Project Blue Book record for a sighting reported in Duluth, Minnesota, on August 18, 1966. Two witnesses, a 59-year-old and a 22-year-old hospital maintenance man, reported observing two round, bright red objects with flashing lights. The witnesses described the objects as bobbing up and down while moving toward the east. The observation lasted approximately five minutes. The witnesses, who were outdoors in a residential area, reported that the objects were silent and appeared to be about one mile away. The weather was clear and dry. The report includes a follow-up letter from Major Hector Quintanilla, Jr., Chief of Project Blue Book, dated September 1, 1966, informing the witness that the initial information provided was insufficient for evaluation and requesting the completion of FTD Form 164. The military assessment of the incident, recorded in a routine message, concluded that the objects were a 'Possible (Aircraft)' sighting. It was noted that a Cessna aircraft was performing touch-and-go maneuvers at the Duluth airport at the time of the sighting, but the reporting controller explicitly stated that this aircraft was distinct from the reported UFO.
