“Falcon Lake UFO”
Stefan Michalak of Winnipeg, Canada, claimed he encountered two UFOs while prospecting near Falcon Lake, Manitoba, Canada, on 20 May 1967, at 12:15 p.m.
One of the UFOs landed about 160 feet away from him. The door of the UFO opened. He approached the UFO and looked inside. After a few moments the UFO started to rotate and something like an exhaust vent was now in front of him. A blast of hot gas shot from the vent onto his chest, setting his shirts on fire and causing him severe pain. Burn marks in the shape of a grid were left on his chest:
