Project 10073 Record: UFO Observation, Minot AFB, North Dakota, 24 October 1968

On 24 October 1968, a series of sightings of unidentified aerial phenomena occurred in the vicinity of Minot Air Force Base, North Dakota. The events involved multiple observers, including the crew of a B-52 bomber on a practice penetration run, as well as security personnel at various missile launch facilities. The B-52 crew reported an unidentified radar blip that initially traveled at approximately 3,000 mph, later hovering near the aircraft and causing temporary interference with the B-52's UHF radio transmissions. Simultaneously, security personnel at missile sites reported sightings of a bright, reddish-orange object that hovered, moved in various directions, and emitted a sound similar to a jet engine. During this period, a security alarm was triggered at one of the missile sites, and upon investigation, guards found an outer door open and a combination lock tampered with. The Foreign Technology Division (FTD) conducted an investigation into the reports. Their official conclusion was that the visual sightings were likely attributable to the star Sirius, the B-52 aircraft itself, and atmospheric conditions, specifically a temperature inversion causing scintillation. The radar anomalies and radio interference were attributed to plasma phenomena, similar to ball lightning. The security breach at the missile site was investigated separately and was not officially linked to the aerial sightings. The report emphasizes that the sightings were likely routine, with the plasma observation being the only scientifically interesting aspect.
