The Falcon Lake Incident (1967)
On May 20, 1967, amateur prospector Stefan Michalak watched two cigar-shaped craft land near Falcon Lake, Manitoba. Approaching one, he was knocked down by a scorching blast that set his shirt ablaze. Grid-pattern burns on his chest and weeks of lingering illness afterward made this one of Canada's best-documented cases.

Why it endures
Real physical burns, documented by photograph, and soil that tested positive for radioactivity unexplained at the time.
Official version (contested)
The soil's radioactivity was eventually traced to a natural radium vein. Michalak's burns and illness remain unexplained.
