What was reported

On the evening of 23 November 1953 Air Defense Command radar at Sault Ste. Marie tracked an unidentified target over Lake Superior near the Soo Locks, and an F-89C from Kinross AFB with pilot Felix Moncla and radar operator Robert Wilson was scrambled. Ground controllers saw the two radar returns converge and merge at about 8,000 ft, after which the fighter's IFF signal vanished; no wreckage or bodies were found. The official accident report says the target was an off-course Royal Canadian Air Force C-47 and that the F-89 probably crashed during the intercept; the Canadian pilot later denied being intercepted, and Donald Keyhoe popularised the case as an aircraft taken by a UFO. A 2006 claim that divers had found the wreck was exposed as a fabrication.

What officials concluded

Resolved

Crash during the intercept of an off-course RCAF C-47 (USAF accident report)
