Martin-Handasyde Transatlantic Monoplane

   One of the most promising of the contenders for the ?10,000 Daily Mail transatlantic prize was the Martin-Handasyde design. A side-by-side two-seater, it followed the general lines of previous designs by the same firm. A four-bladed propeller, 12 ft. in diameter, was fitted to its twelve-cylinder 225 h.p. Sunbeam engine. To enable the machine to float, should it be forced to descend on to the sea, the fuselage was provided with a waterproof compartment which extended rearwards for 14 ft. from the engine bulkhead. Another aid to survival was provided by a telescopic signalling mast which was stowed in the fuselage.
   Load-carrying requirements necessitated the use of a wing of broad span and large area, and this was mounted at shoulder level on the upper longerons. Surprisingly, in such an advanced design, wing-warping was preferred to the use of ailerons, the wing panels being braced with kingposts and wire. Upon take-off the two-wheeled undercarriage was to be released, landing being effected on the long, fixed skid.
   The machine was being constructed at Brooklands during May, 1914, and it was intended that Gustav Hamel should pilot it for the projected West-to-East crossing from Newfoundland to Ireland. These plans received a tragic and abrupt setback when Hamel disappeared while flying the English Channel on 23rd May, 1914. The Martin-Handasyde Transatlantic was one of the most advanced, largest and most powerful designs to have been attempted in its time; financial backing for it was obtained from the Scottish-Canadian financier and sportsman, MacKay Edgar.
