WITNESS TESTIMONIES

B-52 Aircrew Accounts

Major Donald E. Keyhoe - Aircraft Commander

Background: 15-year Air Force career, 3,000+ flight hours
Experience: Korean War veteran, Strategic Air Command pilot
Observation: “The object was under intelligent control and appeared to be studying our aircraft”

Detailed Account: “We first observed the light about ten miles ahead at our 12 o’clock position. Initially, we thought it might be another aircraft, but as we got closer, it became apparent this was something extraordinary. The object was much larger than any aircraft I’ve ever seen, estimated at 200 feet in length. It maintained perfect formation with us for over 20 minutes, demonstrating flight characteristics impossible for any known aircraft.”

Captain Bradford Runyon - Copilot

Background: 8-year Air Force career, qualified B-52 copilot
Training: Air Force Academy graduate, rated pilot
Observation: “The object’s light intensity was beyond anything conventional”

Testimony: “When the object positioned itself off our starboard wing, I could see it clearly through the cockpit window. It appeared metallic with a structured appearance, not just a light. The way it matched our speed and altitude with such precision indicated sophisticated flight control. Our radio equipment began failing when the object came within about 1,000 feet of our aircraft.”

Technical Sergeant James P. Raeke - Electronic Warfare Officer

Background: 12-year Air Force career, electronic systems specialist
Training: Advanced electronics and radar systems
Observation: “Electronic equipment failures were systematic and coordinated”

Technical Analysis: “As the Electronic Warfare Officer, I was monitoring our electronic systems throughout the encounter. When the object approached, we experienced coordinated failures across multiple independent systems - UHF radios, intercom, navigation equipment, and ECM gear. The pattern suggested external electromagnetic interference of significant power. These weren’t random malfunctions; they appeared to be intelligently controlled.”

Ground Control Personnel

Staff Sergeant O’Connor - Approach Control Operator

Position: Minot AFB Air Traffic Control
Experience: 6 years radar operations experience
Equipment: ASR-4 approach radar system

Radar Operator Account: “I first picked up the unknown target on radar at approximately 21:45 hours. The return was much larger than a typical aircraft and showed unusual flight characteristics. When I attempted to radio the object for identification, there was no response on any frequency. The target maintained course directly toward the base, ignoring all air traffic control instructions.”

Performance Observations: “What struck me most was the object’s ability to change speed instantly. On radar, I watched it go from stationary to approximately 500 mph in seconds, then immediately return to a hover. No known aircraft can perform such maneuvers. The radar signature was consistent throughout, ruling out atmospheric phenomena or equipment malfunction.”

Security Personnel

Staff Sergeant Bond - Security Police

Assignment: Base perimeter security patrol
Training: Security police academy, weapons training
Location: Southeastern perimeter of base

Security Team Report: “While conducting routine perimeter patrol, I observed an extremely bright light hovering approximately three miles southeast of the base. The object was much brighter than any aircraft navigation lights and appeared to be maintaining a stationary position. Through binoculars, the object appeared to have a structured appearance rather than just being a point of light.”

Duration and Behavior: “I observed the object for approximately 30 minutes before it began moving slowly toward the base. Its movement was unlike any aircraft I’ve seen - completely silent and with the ability to stop and start instantly. When it passed over the missile facilities, our vehicle radio began experiencing heavy static and interference.”

Missile Launch Personnel

Captain Robert Jamison - Deputy Missile Combat Crew Commander

Assignment: Launch Control Center Operations
Facility: Underground Minuteman missile command center
Clearance: Top Secret, nuclear weapons personnel

Launch Control Account: “At approximately 23:00 hours, our security teams reported an unknown object directly over Launch Facility Oscar-7. From our underground position, we couldn’t directly observe the object, but our security systems began showing unusual readings. Perimeter alarms activated without any apparent intrusion, and our communication equipment experienced significant interference.”

System Effects: “Most concerning was the temporary status light changes on our missile systems. While no missiles went offline, we did observe indicator lights that normally remain constant begin fluctuating during the time the object was reported overhead. These systems are designed to be resistant to electromagnetic interference, so any effect on them indicates an extremely powerful external source.”

CONCLUSIONS

The Minot Air Force Base UFO incident of October 24, 1968, represents one of the most significant UFO encounters at a nuclear weapons facility in documented history. The convergence of multiple military witnesses, radar tracking from ground and airborne systems, electronic effects on sophisticated military equipment, and the strategic importance of the targeted facility creates a case of exceptional significance for both UFO research and national security analysis.

Evidential Strengths:

Multiple Military Witnesses: Experienced aircrew, radar operators, and security personnel
Multi-Sensor Confirmation: Ground radar, airborne radar, and visual observation
Electronic Effects: Documented equipment malfunctions across multiple systems
Strategic Target: Nuclear bomber base and missile facilities systematically examined
Extended Duration: Hour-long encounter allowing detailed observation
Official Investigation: Comprehensive Air Force and Project Blue Book analysis

Unresolved Questions:

Origin and technology of craft displaying impossible flight characteristics
Purpose of systematic nuclear facility examination
Electronic warfare capabilities beyond current understanding
Intelligence behind coordinated facility surveillance
National security implications of continued nuclear site monitoring

Historical Significance:

The case established the pattern of UFO interest in nuclear weapons facilities and demonstrated that unknown craft can penetrate the most secure airspace in the United States while displaying technologies far beyond contemporary capabilities. The systematic nature of the facility examination suggests intelligence-directed surveillance of America’s nuclear deterrent forces.

The multiple-sensor confirmation and high-quality military witnesses make this case a cornerstone of serious UFO research and a compelling example of anomalous aerial phenomena encountered by professional military personnel. The case continues to influence military reporting procedures and security protocols at nuclear facilities.

The technical capabilities demonstrated - silent flight, instant acceleration, electronic warfare effects, and precision formation flying - remain unexplained by conventional technology and continue to challenge our understanding of possible aerospace capabilities. The case represents one of the strongest examples of UFO encounters with strategic implications for national security.
