Radley-England Water Plane

Designed and built in Britain by James Rladley and Eric Gordon England, the Waterplane was the world’s first tri-motor aeroplane. Its three 50-hp rotary engines were mounted between the wings. each engine had its own controls and an independent chain drive linking it to the propeller shaft above.
Together the engines drove a large fourbladed pusher propeller.
The aircraft was sizeable for its day, carrying five passengers in its twin floats, or hulls. The pilot occupied the front seat in the starboard float, with two passengers behind him. Mounted above the floats was a biplane superstructure, with a tailplane and twin rudders carried on booms.
In initial tests as a landplane, with a temporary wheeled undercarriage, the aircraft proved an excellent flyer. Shifting to its intended element, the Waterplane was flown from the River Adur at Shorehara in Sussex and t hen from the sea at Brighton.
Disaster struck on 26 May 1913, when one of the floats hit an object on landing and was holed. The aircraft was rebuilt with clinkerbuilt hulls and one 150-hp Sunbeam engine.
However, the new engine proved troublesome and the aircraft never flew again.
