The Burgess-Dunne Aerohydroplane of 1914 was an inherently stable tailless biplane designed by John W. Dunne of England. The Burgess Company of Massachusetts bought the U.S. manufacturing rights and reconfigured it as a waterborne aeroplane. The ailerons were rigged to allow independent operation, thus permitting the ailerons to also function as elevators. The U.S. Army Signal Corps purchased Burgess-Dunne No. 3, a wheeled land version, for use at North Island, San Diego, California. A 100 h.p. Curtiss O-X engine was the standard powerplant, but the Signal Corps machine was powered by a 135 h.p. Salmson radial engine.
