On the morning of 20 May 1967, Stefan Michalak — an industrial mechanic from Winnipeg who also worked as an amateur prospector — was in the woods near Falcon Lake, in Whiteshell Provincial Park, Manitoba, looking for quartz. It was a Saturday, a fine spring day. He had been prospecting in the area before.
What happened over the next few hours left him with burns on his chest, weeks of illness, and a case file that the Canadian government still holds as one of its most puzzling UFO reports.
The two discs
Michalak later told investigators that he first noticed two disc-shaped objects in the sky. One rose and flew away. The other descended and landed on a flat rock about 50 metres from where he stood.
He watched it for a while, then walked towards it. The craft, he said, was about 12 metres across, metallic, with a domed top. He could hear a humming sound and feel warm air. He called out in English, then in Polish, Russian, and German, offering help if the occupants needed it. There was no answer.
Curious, he moved closer and peered inside through an opening. He described seeing a panel of blinking lights. Then the craft began to rotate. A grid-like exhaust vent on its side turned towards him, and a blast of hot gas struck his chest and stomach, setting his shirt and hat on fire.
Michalak tore off his burning clothes and stumbled away. He was sick — nauseous, vomiting — and he made his way back to his motel in Falcon Lake, then to Winnipeg, where he sought medical help.
The burns
The medical evidence is the heart of the Falcon Lake case. Doctors in Winnipeg found first-degree burns on Michalak’s chest and abdomen — irregular, roughly circular marks, some about the size of a silver dollar, arranged in a grid pattern. The burns were consistent with a blast of hot gas through a grille, exactly as Michalak described.
He was also suffering from nausea, vomiting, headaches, and weight loss in the weeks that followed. Doctors at the Mayo Clinic in the United States examined him and found him to be of sound mind. A laboratory at Pinawa, run by Atomic Energy of Canada, tested him for radiation sickness and found none — the burns were thermal or chemical, not radiation burns.
Investigators from the Royal Canadian Mounted Police and the Royal Canadian Air Force visited the site. They found a circular area of scorched ground and collected soil samples. Tests on the soil found traces of radioactivity — about 0.3 microcuries — but at levels far too low to cause Michalak’s symptoms, and consistent with natural background sources in the rock.
The second set of marks
The case took a strange turn in January 1968, eight months after the incident. Michalak showed investigators a new set of marks on his body — a neat grid of evenly spaced burns, photographed for the record.
A psychiatrist who examined him concluded that these new marks were likely self-inflicted, and that they differed clearly from the original 1967 burns, which were irregular and medically documented. The 1968 marks damaged Michalak’s credibility with some investigators, but they did not erase the 1967 medical evidence — the original burns had been examined by doctors within days of the event, before any suggestion of a hoax had arisen.
What do the sceptics say?
The most common sceptical explanation is that Michalak burned himself accidentally — perhaps with a hot stove or a campfire — and invented the craft to explain the injuries. But the burns’ grid pattern, their location on his chest and abdomen, and the fact that he sought medical help promptly, make an accidental burn hard to fit to the evidence.
Others suggest the whole story was a hoax for attention or money. Michalak did receive some publicity, but he never profited in any significant way, and he stuck to his story for the rest of his life. He died in 1999, still insisting that what he described had happened.
The Canadian government has never closed the file. Falcon Lake remains one of the most thoroughly documented UFO cases in Canadian history — not because anyone proved a craft landed there, but because the injuries were real, medically confirmed, and never explained.
What the evidence says
- Documented: On 20 May 1967, Stefan Michalak reported approaching a landed disc-shaped craft near Falcon Lake, Manitoba, and being burned by a blast of hot gas from a grid-like vent. Doctors confirmed first-degree burns on his chest and abdomen, in an irregular grid pattern.
- Documented: The Mayo Clinic found Michalak of sound mind. Atomic Energy of Canada found no radiation sickness. The RCMP and RCAF investigated the site and found scorched ground; soil samples showed only low-level radioactivity.
- Documented: In January 1968, Michalak presented a new set of evenly spaced marks; a psychiatrist concluded these were likely self-inflicted and distinct from the original 1967 burns.
- Claimed: Michalak said he saw two discs, looked inside one, and saw a panel of blinking lights.
- Proposed explanations: Accidental burn, hoax — neither has been supported by evidence that fits the documented 1967 injuries.
What remains unknown
No craft was found, no other witness saw the discs, and no explanation has ever been established for how Michalak received the burns documented by his doctors. The Falcon Lake incident remains an open file — and a reminder that the strongest UFO cases are often the ones with a medical record attached.
