Minot Air Force Base UFO Incident
Ground personnel and a B-52 bomber crew at a nuclear missile base in North Dakota simultaneously tracked an unidentified luminous object by radar and visual observation, in a case that Project Blue Book failed to explain convincingly.

Background
On October 24, 1968, during predawn hours, security teams at nuclear missile launch facilities around Minot Air Force Base in North Dakota reported a bright, luminous object maneuvering at low altitude near their positions.
The Incident
Multiple maintenance and security personnel across several dispersed sites independently confirmed the sightings. The object exhibited the following characteristics:
- Alternately hovered and moved slowly
- Executed rapid course changes
- Appeared as a large, brilliant light positioned on or very near the ground surface
A B-52H Stratofortress on a calibration approach to the base was vectored by ground control to investigate. The bomber crew acquired the object on their onboard radar at approximately one nautical mile range and observed the luminous light simultaneously.
Radar Evidence
Multiple independent radar systems tracked the object:
- The B-52H's onboard radar registered the target through multiple sweeps
- The object appeared to accelerate beyond tracking capability
- Minot Air Force Base's own ground radar systems registered anomalous returns during the same timeframe
Investigation and Conclusions
Project Blue Book investigated the incident and attributed the visual observations to the star Sirius and the planet Vega, combined with atmospheric plasma effects near the missile sites.
Witnesses widely regarded this explanation as unsatisfactory, emphasizing that:
- The object was observed at close range
- It was tracked on multiple independent radar systems
- Its behavior was inconsistent with any astronomical body or natural phenomenon
Significance
The Minot AFB case stands out for its convergence of multiple independent evidence streams: ground visual sightings by trained military personnel, airborne radar tracking by a B-52 crew, and ground radar confirmation. Its occurrence at a nuclear weapons facility placed it within a broader pattern of unexplained incursions near strategic military assets.
