Blériot-SPAD S.45

The Blériot-SPAD S.45 was a large, four-engine French airliner that appeared at the 1921 Paris Salon, able to carry fifteen passengers or to be adapted as a bomber. It was a biplane designed by André Herbemont, retaining the combination of a swept upper wing with a smaller unswept lower one from his earlier, smaller Blériot-SPAD airliners, and it was largely of wooden construction. Four 275 hp Hispano-Suiza water-cooled V8 engines drove it, two close together in pusher configuration on top of the upper wing and two further apart on the lower wing. The fuselage was a wooden circular section monocoque, and the three crew sat in open cockpits near the nose. There is no known record of it flying.
