Kinross Incident

In 1953, the United States Air Force pilot Felix Moncla was stationed at Kinross Air Force Base in Michigan when a mysterious airborne object appeared on ground radar. Lt. Moncla scrambled his F-89 Scorpion interceptor to investigate the anomaly, but as he grew nearer, the ground radar reported seeing his aircraft suddenly merge with the object. Both objects immediately vanished from radar vision. Theories centered on a collision with an unreported Canadian aircraft, but Canadian authorities denied any such aircraft being in the area. No confirmed debris or wreckage was discovered and it still remains a mystery what happened to Felix Moncla.
