The SNCASE SE-1010 was a late 1940s French photo-survey aircraft designed and built by SNCASE for the Institut Géographique National. One prototype was built, but it crashed and the project was cancelled.
Design and development
In 1945 SNCASE designed a "stratospheric" transport for transatlantic postal work designated the SE-1000. The design was not built, but after the nose section was modified, it was built as high-altitude photo-survey aircraft for the Institut Géographique National, and re-designated the SE-1010. If it was decided not to use it as a survey aircraft, it was proposed to produce it as a 14-passenger transport instead.
The SE-1010 was a sleek, four-engined, mid-wing monoplane powered by four Gnome-Rhône 14R 14-cylinder two-row air-cooled radial engines. The prototype SE-1010, with French test registration F-WEEE, first flew on 24 November 1948. On 1 October 1949 the prototype entered a flat spin during test flying from Mariganne and crashed, killing the six person crew near Carcès. The project was canceled and the three aircraft being built were not completed.
