In 1967, Stefan Michalak reportedly encountered an unidentified flying object near Falcon Lake, Canada. Michalak was close enough to touch the object but then, it suddenly lifted off, knocking him on his back. Michalak claimed to have been burnt by the object´s exhaust vent that was covered with a grid. The hot gases even left burn marks on his chest as it can be seen in the photo. After this bizarre accident, Michalak got very sick, suffering from symptoms typical of radiation but the nature of the burns has remained a mystery.
