The Albatros L 76 Aeolus was a German military reconnaissance aircraft built by Albatros Flugzeugwerke in 1927. The plane had wooden dual-spar wings with plywood skins supported by N-type struts and a fabric-covered fuselage made of welded steel tubing. The aircraft was used for testing,[1] as well as the training of the Soviet Air Force.[2] It was difficult to fly, and killed many people, including Emil Thuy,[3] who crashed near Smolensk on June 11, 1930,[1] and Paul Jeschonnek, who crashed near Berlin on June 13, 1929. As a result, it had to be improved, leading to the production of the Albatros L 77v, designed by Ernst Heinkel Flugzeugwerke.
