(October 21, 1926 – presumed dead November 23, 1953) was a United States Air Force pilot who disappeared while performing an air defense intercept 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 object of the intercept was a Royal Canadian Air Force (RCAF) aircraft.
According to the report, the pilot of the Canadian aircraft was later contacted and stated that he did not see the intercepting plane and did not know that he was the subject of an interception.
However, on several occasions, the RCAF denied that any of their aircraft was involved in any incident on that day, in correspondence with members of the public asking for further details of the intercept.
