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
[edit]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.[1] If it was decided not to use it as a survey aircraft, it was proposed to produce it as a 14-passenger transport instead.[1]
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.[1] 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.[1]
