Advertisment:On May 20 1967, Stefan Michalak saw something at Falcon Lake, in Manitoba, Canada, that has yet to be explained, but it turned his and his family's lives upside down. And although the incident has gone down in UFO lore history, Michalak never claimed that he believed he saw an extraterrestrial ship. His son Stan Michalak told the Canadian Broadcasting Corporation (CBC) about the vivid and traumatic memory of his father coming home sick and burned from the encounter, and smelling like sulphur and "burned motor." He looked pale, haggard," Michalak told CBC. Stefan Michalak was a hobby prospector and had gone to search Falcon Lake for quartz, according to travel and culture site Atlas Obscura.
