Kinross incident (Felix Moncla)
A USAF interceptor sent after an unknown radar target over Lake Superior vanished.
1953 CE · 47.50, -87.00 · status: explained
The account
On 23 November 1953 Lt Felix Moncla, on temporary duty at Kinross AFB, Michigan, was performing an air-defence intercept over Lake Superior when he disappeared. Ufologists later presented it as an aircraft 'taken' by a UFO.
The sceptical view
The Air Force said the target was an off-course Royal Canadian Air Force C-47 whose pilot did not know he was being intercepted, and that Moncla crashed into the lake.
The researched reading
A real and tragic loss of an interceptor and two airmen. An ordinary target and a night crash over water explain it; the UFO version rests on dramatised retellings.
| Explanation | Weight | Why |
|---|---|---|
| Something known, misidentified | 72% | The radar target was identified as an off-course RCAF C-47; the F-89’s loss over Lake Superior at night fits a crash from spatial disorientation, a common cause of interceptor losses in the period. |
| Perception, memory or mind | 8% | The "merged blips" story was dramatised by Donald Keyhoe and later retellings, turning a crash into an abduction. |
| Genuinely anomalous | 7% | The RCAF denied any of its aircraft was intercepted, and the wreck has never been found. |
| A known natural phenomenon | 5% | Radar returns can merge when two aircraft are close; icing or weather could have contributed to the crash. |
| A hoax or fabrication | 4% | A 2006 claim that divers had found the wreck was itself a hoax, but it does not affect the original event. |
| Secret human technology | 3% | No secret aircraft explains the target better than the C-47. |
| A poorly understood natural phenomenon | 1% | Nothing points to an unusual natural event. |
Official position: The Air Force concluded the target was an RCAF C-47 and that Moncla probably crashed into the lake, possibly from vertigo.
