[1] Following the end of the Second World War, the French aircraft manufacturer SNCASE proposed a very large, long-range flying boat, the SE-1200, which was intended to carry 125 passengers across the Atlantic Ocean.
[1][3] To enable aerodynamic tests of the design a flying scale model approximately one-third size was built.
[1] The SE-1210, registered F-WEPI, first flew on 9 June 1948 on the Étang de Berre near SNCASE's factory at Marignane, Marseille.
[1][3] After modification it was passed to the Centre d'essais en vol (CEV) for further testing which continued from December 1948 to April 1949.
[4] Following the cancellation of the SE-1200 project, testing of the SE-1210 was abandoned, with it being flown for the last time in March 1951, with the flying boat being scrapped in 1952.
