First Lieutenant Felix Eugene Moncla, Jr. (October 21, 1926 – presumably died November 23, 1953) was a United States Air Force pilot who mysteriously disappeared while pursuing an unidentified flying object over Lake Superior in 1953. This is sometimes known as The Kinross Incident, after Kinross Air Force Base, where Moncla was on temporary assignment when he disappeared. The U.S. Air Force reported that Moncla had crashed and that the "unknown" object was a misidentified Royal Canadian Air Force aircraft.
