what were world war 1 planes made of
Aviation in World War I Almost all the fighters in service with both sides, with the exception of the Fokkers' steel-tube fuselaged airframes, continued to use wood as the basic structural material, with fabric-covered wings relying on external wire bracing. However, the first practical all-metal aircraft was produced by Hugo Junkers, who also used a cantilever wing structure with a metal covering. The first flight tests of the initial flight demonstrator of this technology, the Junkers J 1 monoplane, took place at the end of 1915 heralding the future of aircraft structural design.
