What happened
On May 20, 1967, Stefan Michalak, an engineer of Polish descent and an amateur geologist, was searching for quartz in the woods near Falcon Lake. Around noon he saw two red, glowing, cigar-shaped objects, one of which landed on a rock a few dozen meters away. For an hour he watched it up close and heard voices coming from inside. When he approached and touched the object with a gloved hand, the material melted, and hot gas burst from an opening, setting his shirt on fire. Michalak suffered burns on his chest in a regular, grid-like pattern and experienced nausea and weight loss. The case was investigated by the RCMP, the Canadian military, and the Condon Committee.
Witnesses
Stefan Michalak; no one else saw the landing, but doctors and investigators documented his injuries and the traces on the rock.
Explanations and hypotheses
Investigators found no convincing explanation. Elevated radiation levels and metal fragments were detected at the site, but their origin was never determined; contamination with radium was later suggested. Skeptics suspect a hoax or an accident, such as a burn from a campfire, but inconsistencies in his account were never proven. The Condon Committee classified the case as unsolved. In 2018 the Royal Canadian Mint issued a coin dedicated to it.
Unexplained There is no convincing explanation.
