Bleriot-SPAD S.33


Manufacturer: Blériot
First flight: December 12 1920
Primary users: Franco-Roumaine, CMA SNETA
Number built: ca. 41

The Bleriot-SPAD S.33 was a small French airliner developed soon after World War I. A great success, the S.33 dominated its field throughout the 1920s, initially on CMA's Paris-London route, and later on continental routes serviced by Franco-Roumaine. The aircraft was a biplane of conventional configuration whose design owed much to the Blériot company's then-recent fighter designs such as the S.20. Four passengers could be accommodated in an enclosed cabin within the fuselage, and a fifth passenger could ride in the open cockpit beside the pilot.

One interesting development was a sole example converted by CIDNA to act as a blind-flying trainer. A set of controls was installed inside the passenger cabin, the windows of which had been blacked out.
