The Stringfellow Flying Machine of 1848 was built by John Stringfellow using a Henson steam engine modified by himself. The model was demonstrated attached to a cable inside a lace production shed at Chard, Somerset, England and at Cremorne Gardens in 1848 flying a distance of 40 m before crashing into a wall. Having a wingspan of 10.5 feet and a wing surface area of 12 square feet, it used a six and three-quarter pound engine. This was the first successful flight by a heavier-than-air machine to fly under its own power.
