SNCASE SE-1010

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.^[1]

Design and development

In 1945 SNCASE had designed a "stratospheric" transport for transatlantic postal work designated the SE-1000, it was not built but given a modified nose-section it was built as high-altitude photo-survey aircraft for the Institut Géographique National and designated the SE-1010.^[1] If not used as a survey aircraft it was proposed to produce it as a 14-passenger transport.^[1]

The SE-1010 was a sleek-looking, four-engined, mid-wing monoplane powered by four Gnome-Rhône 14R 14-cylinder two-row air-cooled radial engine. 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, it crashed killing the six crew near Carcès. The project was canceled and the three aircraft being built were not completed.^[1]
