Ogden, Utah Plumber, Brigham Ballantyne, turned into a human cannonball on the morning of 4 May 1913. Trying to see where he was going in an old sewer line, he struck a match for light. His next memory was being 10 feet away from the opening of the pipe.
Sewer gas ignited when the match was struck turning the sewer line into a cannon with Mr. Ballantyne acting as the projectile. His life was saved due to a covering of mud that protected him from serious burns.
