The first result of Stringfellow's efforts was the 1848 machine shown below, which was powered by two contra-rotating propellers driven by one of Stringfellow's powerful and lightweight steam engines. The first attempt to fly the 10 foot wing span machine took place indoors, and a lack of proper balance resulted in a failure and damage to the machine. The second attempt was a rather wonderful success, for the flying machine left a guide wire and flew straight and true for about 30 feet.
