Cubana de Aviación
The 310 series (the Model 318) also saw transatlantic service with "Cubana de Aviación" starting in 1958, in spite of the Cuban Revolution the airline had a special accord with British aircraft manufacturers to maintain this model of aircraft. In 1975, multiple Cuban Britannias were used to transport hundreds of soldiers of the Cuban Revolutionary Armed Forces to Angola in Operation Carlota, a proxy war. "Cubana de Aviación" continued to fly its fleet of Britannias until March 1990.
