Paris-based photographer Laurent Thion, recently photographed ONERA’s S1Ch Wind Tunnel, which was the biggest in France until the end of WWII. Iit was here that planes such as the Caravelle and Concorde were tested, as well as the first ‘delta wing’ airplane cars and the Volkswagen. French skiing champion Jen-Claude Killy also used the wind tunnel.
Although this tunnel is no longer in use, it was recently saved from destruction and is now classified as an historic building. This wind tunnel was built between 1932 and 1934 and it made possible the testing of a real plane of 12m, with ignited engine and pilot on board. The wind tunnel is 120m in length and 25m high.
