Blériot-SPAD S.25

The Blériot-SPAD S.25 was a single-seat long-distance aeroplane built at the request of Leith Jensen, who wanted to fly from Newfoundland to Iceland. It was a biplane with a monocoque fuselage of wood and canvas construction, designed with a watertight fuselage and with quick-emptying tanks that could serve as floats where appropriate. Jensen's attempt was abandoned after the feat of Alcock and Brown, so the S.25 flew on 29 August 1921 as a sports aircraft instead. The specification lists a crew of one, a length of 6.50 m, a wingspan of 8.12 m, an empty weight of 467 kg, a gross weight of 931 kg and a maximum speed of 160 km/h from one 71 kW Le Rhône nine-cylinder rotary piston engine.
