Sud-Ouest Bretagne

The Sud-Ouest S.O.30 Bretagne was a 1940s French airliner built by Sud-Ouest.

Design and development
The Bretagne (Engl. "Brittany") was designed by a group of designers and engineers who were based at Cannes from May 1941 following the invasion of France. The design was for a medium capacity civil transport, a twin-engined mid-wing cantilever all-metal monoplane. The prototype (designated the S.O.30N) first flew on 26 February 1945.

Operational history
The initial production version was designated the S.O.30P Bretagne with two versions with different engines. The aircraft operated with a crew of five and could carry between 30 and 43 passengers. A cargo version (the S.O.30C) was produced, with a revised interior and strengthened floor and large cargo door. The aircraft was operated as an airliner, but mainly by the French military forces as a medium transport.

Some aircraft were fitted with two underwing Turbomeca Palas turbojet engines for auxiliary power. Other aircraft were used for engine-trials fitted with the SNECMA Atar 101 and licence-built Rolls-Royce Nene turbojets.
