Polish-Canadian amateur prospector whose May 1967 close encounter at Falcon Lake, Manitoba, left him with documented grid-pattern burns and radiation-like symptoms. The RCAF and RCMP case file is held at Library and Archives Canada.
Stefan Michalak was a Polish-Canadian industrial mechanic and amateur prospector involved in the famous 1967 Falcon Lake incident in Manitoba, Canada. He claimed to have approached two landed, cigar-shaped UAPs, subsequently suffering severe burns to his abdomen when one of the crafts vented a grid-like pattern of exhaust gas. Michalak's key contribution is the extensive physical and medical evidence supporting his encounter, including radiation burns, melted clothing, and radioactive traces at the landing site. He never sought financial gain and maintained his story until his death despite intense government and medical scrutiny. The Falcon Lake case is widely considered Canada's most documented and compelling physical UAP encounter.
