On November 23rd, 1953 over Lake Superior, Air Defence Command radar started to track an unidentified target moving at 500 miles per hour over the lake. A F-89C all-weather jet interceptor from Kinross AFB took off in hot pursuit.

Radar operators watched closely as the aircraft approached the UFO. The all of a sudden the two blips merged and then faded on the screen, and all communication with the interceptor ceased. An extensive land and water search found no trace of the craft or the two men aboard: pilot Lieutenant Felix Moncla, Jr., and radar observer Lieutenant R.R Wilson.

Later. after aviation writer Donald E. Keyhoe broke the story in his best selling book „The Flying Saucer Conspiracy (1955)”, the Air Force insisted that the UFO had proved to be a Royal Canadian C-47. They claimed that the F-89C had not actually collided with the Canadian transport plane, but that something „unspecified” had happened, and the interceptor crashed.

In 1958 a leaked Air Force document made it clear that officials considered the Kinross incident a UFO encounter of the strangest kind. The document quoted the radar operator as saying „It seems incredible, but the blip apparently just swallowed our F-89”
