The "Brumah I" was the first machine built by the two seventeen-year-old Harry A. Bruno and Bernard H. Mahon (hence the name) of Montclair, New Jersey, crashed on its first flight from the barn. The Brumah II, with a span of only 16 feet, was called the world’s smallest monoplane. It was flown on sled runners down an ice-coated hill on Christmas Eve 1910. It crashed then too but might have been re-built, but there is no indication that it was ever actually fitted with a motor.
