Blériot 75 Aerobus

The Blériot Bl.75 Aerobus was a large French biplane airliner built by Blériot shortly after the First World War, the airliner version of the Bl.74 bomber and transport. It had a longer rear fuselage and an enlarged vertical tail surface but was otherwise similar to the Bl.74, with the large double bubble teardrop fuselage mounted on the lower wing. Like its siblings the Bl.73 and Bl.74 it was a single prototype. Unlike them it was not lost in a test flight accident, and the flight tests of the sole Bl.75 were promising, but no orders followed. It was exhibited at the Aero Salon in Paris in December 1919, where it was judged unsuccessful beside the SPAD designs shown with it.
