Washington DC man Harry Orme’s machine was generally similar to a Wright biplane, but differed in several respects. It was powered by an 8 hp 45 lb Belgian-made motor driving two propellers, with variable pitch. Over the top wing was a smaller “mushroom-shaped” wing on springs, capable of being distorted, and “intended to act as a bird’s tail does”, which Orme claimed would “prevent the sudden plunging of the aerial craft to the earth if any mishap occurs.” It didn’t help in December of 1908 when a loose wire got in the way of the propellers, breaking them, and ruining many support wires. The plane probably never flew again
