Roe II Triplane
The Roe II Triplane, sometimes known as the Mercury, 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. First flown in April 1910, two examples were built, one as a display machine for Roe's new firm, and the second was sold to W. G. Windham.
Displayed at the Olympia Aero Show in London, the price was £550 with tuition.
Roes machine was sent to Brooklands for flight trials but rolled twice on take-off. After the second crash AV changed from wing warping to a control column.
The performance of the aircraft improved and it was finally dispatched by rail to the Blackpool Flying Meeting with the Roe III but on the journey the goods train set fire due to sparks coming out of the engine and landing on the truck. Both the Roe III and Mercury were totally burnt-out.
The longest recorded flight made by the II Triplane was only 600 ft (180 m).
