Lawson AFB Encounter: White Disc Orbits F-51 for Ten Minutes

The Lawson AFB encounter of July 1951 represents an early Cold War-era case in which a trained military pilot had sustained, close-range contact with an unidentified disc-shaped object under clear daylight conditions — making it one of the more credible aviation UAP reports of the immediate postwar period.

The Incident 1st Lieutenant George H. Kinmon Jr. was flying a routine sortie in an F-51 Mustang when the object first presented itself head-on. It initially dove beneath his aircraft — a maneuver suggesting active awareness of the F-51's position — before settling into a persistent circular orbit around the fighter. The ten-minute duration of this behaviour is remarkable.

Objektbeschreibung Kinmon noted that the disc was perfectly circular when viewed from above. Its surface appeared white and uniform, and it showed no engine intakes, exhaust ports, propellers, or any other propulsion signature. The object was entirely silent throughout.

Manöver und Ende To maintain a 100-meter proximity orbit around an aircraft flying at altitude requires exceptional control authority and situational awareness, qualities far exceeding any drone or experimental aircraft of the era. The manner in which the encounter ended — the object simply disappearing beneath the F-51 — suggests it could accelerate or maneuver in ways that made visual tracking impossible.

Analysis Lacatski includes this case in a systematic discussion of UAP flight characteristics, specifically categorised under the behavior class of objects that "fly circles around aircraft" — a pattern documented across multiple decades and airspace jurisdictions. The U.S. Air Force flight record and Kinmon's testimony provide the primary documentation for this event.
