SNCASO
SNCASO (abbreviated from Société nationale des constructions aéronautiques du sud-ouest, or commonly, Sud-Ouest) was a French aircraft manufacturer, which originated on November 16, 1936, from the merger of the factories of Blériot of Suresnes, Bloch of Villacoublay and Courbevoie, SASO (Société Aéronautique du Sud-Ouest) of Bordeaux- Mérignac, UCA (Usine de Construction Aéronautique) of Bordeaux- Bègles, Société Aérienne Bordelaise (SAB) of Bordeaux- Bacalan and Lioré et Olivier of Rochefort. Additionally, SNCASO built a factory in Déols in 1936.
SNCASO took over SNCAO's assets in 1941.
On March 1, 1957, SNCASO merged with SNCASE (Société nationale de constructions aéronautiques du sud-est), to form Sud Aviation.
