The Roe II Triplane, sometimes known as the Mercury,[1] was an early British aircraft and the first product of the Avro company. It was designed by Alliott Verdon Roe as a sturdier development of his wood-and-paper Roe I Triplane. Two examples were built, one as a display machine for Roe's new firm, and the second was sold to W. G. Windham. The longest recorded flight made by the Roe II Triplane was 600 ft (180 m).
