Morane-Saulnier MS.140

The Morane-Saulnier MS.140 was a French biplane designed as an ambulance aircraft able to operate from small fields, with a hatch behind the pilot into which a stretcher could be slid. For greater utility a second seat with dual control could be fitted instead, so that it could double as a trainer. Only one was built, first flying about 1927. It was backward-looking for a 1927 design, using an 80 horsepower Le Rhone 9C rotary engine, and had an all-wood structure with fabric covering, a single-bay layout with wings of equal span and sweepback on the upper wing only. Its generous wing area gave a low wing loading and the ability to use very small fields. It was noted in the Villacoublay aircraft graveyard in 1937 and may have been sold to the Spanish Republicans at the start of the Spanish Civil War.
