First Lieutenant Felix Eugene Moncla, Jr. Disappears While Pursuing a UFO Over Lake Superior

The 23 November 1953 "Kinross Case," wherein a US Air Force F-89C jet fighter was scrambled from Kinross AFB Michigan on an "active air defense mission" to intercept an "unknown aircraft" and disappeared with two crew members aboard, is considered by many to be one of the "UFO classics." Controversy remains over what the "unknown aircraft," which was the target of the interception, was. USAF records presented here indicate that it was a Canadian aircraft. Canadian officials have denied that any of their aircraft was the target of an interception mission by the USAF on the date in question. The USAF seems to have changed its story over the years about just what Canadian aircraft was being intercepted and has been silent on the method by which they identified the aircraft.

On the night of November 23, 1953, an Air Defense Command radar detected an unidentified "target" over Lake Superior. Kinross Air Force Base, closest to the scene, alerted the 433rd Fighter Interceptor Squadron at Truax Field, Madison, Wisconsin, and an F-89C all-weather interceptor was scrambled. Radar operators watched the "blips" of the UFO and the F-89 merge on their scopes, in an apparent collision, and disappear. No trace of the plane was ever found.
