CAMS 53

The CAMS 53 was a transport flying boat built in France in the late 1920s. Building on the experience gained from the unsuccessful CAMS 51, Maurice Hurel designed an aircraft of similar size and capacity for Aéropostale. The company bought four aircraft straight away for use on its Marseilles-Algiers route, and Air Orient purchased another two. More CAMS 53s were soon ordered by these operators as well as Air Union, and the aircraft were used to link Marseilles with Ajaccio and Beirut. When the various French airlines were absorbed into Air France in 1933, some 25 CAMS 53s were still in operation and continued in use until 1935.
