In 1953, two US Air Force pilots, Felix Moncla and Robert Wilson, disappeared while attempting to intercept an unidentified flying object (UFO) over Lake Superior. On the evening of November 23, the men were dispatched from Kinross Base (now Kincheloe AFB) in Wisconsin after radar detected a mysterious object near the US-Canadian border. Ground control tracked their aircraft approaching the UFO before both blips on the radar merged and vanished. A joint search by US and Canadian forces failed to locate the pilots or their plane. The US Air Force later claimed the pilots had been intercepting a Canadian jet and crashed due to vertigo, but Canada denied any flights in the area that night. Speculation grew as conflicting reports emerged, with UFO researcher Donald Keyhoe calling it “one of the strangest cases on record.” The incident remains unsolved, fueling conspiracy theories of possible extraterrestrial involvement.
