Lake Superior, off the Keweenaw Peninsula / Soo Locks region, United States / Canada border region
The Kinross Incident
On 23 November 1953, USAF F-89C 51-5853 carrying pilot Felix Moncla and radar observer Robert Wilson disappeared during a ground-controlled intercept over Lake Superior. Ground radar showed the F-89 closing on another return until the two returns merged; the F-89's IFF then vanished and neither airc
Why This Case Matters
A genuine military radar/intercept disappearance with a surviving official accident report—far stronger archivally than most 'vanished chasing a UFO' stories, but not evidence that a craft absorbed or attacked the F-89.
Chronology
- 23 Nov evening ground radar detects target near restricted Soo Locks region
- F-89 scrambled from Kinross
- Moncla guided toward target
- radar returns converge/merge
- F-89 IFF and radio contact lost
- extensive search finds no wreckage
- Dec 1953 accident board investigates and identifies intercept target as RCAF C-47
- later UFO literature disputes aspects of official account
The Witnesses
Evidence
The following evidence types are documented for this case:
Conventional explanations: Loss of control/spatial disorientation, mechanical failure or accidental descent into Lake Superior are conventional explanations for the F-89 loss. The other radar return was officially associated with an RCAF C-47, although later disputes about that flight keep part of the chronology contested.
What Remains Unresolved
- Exact cause of F-89 loss
- wreckage location
- complete radar track
- exact position/course of RCAF C-47
- why IFF/radio vanished
- status of alleged 1968 aircraft debris.
Key Takeaways
- The radar merge is not evidence of physical fusion or collision by itself. The documented facts are an intercept, a merged radar display and a missing aircraft.
