The story
Founded by Jules Supervielle and Tydeo Larre Borges on Dec 29, 1936.1
Compañía Aeronáutica Uruguaya SA (The Uruguay Aeronautics Company Ltd.) was founded on December 29, 1936, by the Uruguayan banker Luis J. Supervielle and Colonel Tydeo Larre Borges. The airline intended to concentrate its operations on the busy and financially lucrative Montevideo-Buenos Aires route.
Operations began on March 12, 1938, with two Junkers Ju 52s carrying seventeen passengers and configured as floatplanes. The Junkers 52s were well-built, new, strong, dependable, aircraft and a good economic choice for CAUSA. At the same time the Junkers 52 was used as the main airliner by Deutsche Lufthansa and as transports (and sometimes as bombers) by the Luftwaffe. The Junkers airplanes acquired by CAUSA were the CX-ABA(C/N 5877) baptized "El Uruguayo" and the CX-ABB(C/N 5886) "El Argentino".
CAUSA's entry to the airline market at that time put it in competition with the Argentine airline corporation, Sudamericana de Servicios Aéreos (South-American Air Services), which also connected the ports of the two capitals. By January 1940, a route to the holiday resort of Punta del Este was added. In 1943 another new route was opened between Buenos Aires and Colonia, only 35 miles across the Rio de la Plata. In Colonia, a bus service ran to CAUSA's main offices at Montevideo. These three routes were the only ones operated by the airline in its nearly 30 years of service.
At the end of World War II, CAUSA began competing with the Argentine airline A.L.F.A., precursor of the future Aerolíneas Argentinas, and purchased two modified Short Sunderland flying boats. After reaping success, the company decided to buy a third flying boat. This one was delivered in 1946. The Short Sunderlands were the CX-AFA(C/N SH.5C) "General Artigas", the CX-AKF(C/N SH.6C) ex-"Corporación Sudamericana de Servicios Aéreos" and the CX-AKR(C/N SH 60C) "Capitán Boiso Lanza".
