Latécoère 21

The Latécoère 21 was a French flying boat built in 1925 for use by Lignes Aériennes Latécoère as an airliner on routes between France and North Africa. It was the first of the Latécoère flying boats, and the first aircraft to deliver mail between Marseilles and Algiers. It was a conventional design for the era, with a monoplane wing mounted parasol-fashion. Warren truss-style struts braced the wing to stub wings that acted as sponsons for stability while on the water. The twin engines were placed in tandem push-pull configuration on the wing. Up to seven passengers could be seated in an enclosed cabin, and two pilots sat side by side in separate open cockpits.
