VL Myrsky
The VL Myrsky ("Storm") was a Finnish fighter designed and built by the State Aircraft Factory, Valtion lentokonetehdas, during the Second World War. Finland ordered the design in 1939 so that its air force would not depend on foreign suppliers for a modern fighter. Built largely of wood to conserve scarce metal, the prototype flew in December 1941, but aeroelastic flutter destroyed all three prototypes and killed two test pilots. The production Myrsky II reached reconnaissance squadrons only in August 1944; fifty-one aircraft were built in all. The type flew against the Soviet Union in the Continuation War and against Germany in the Lapland War, but the substitute glues in its wooden structure failed in Finnish weather, and it was withdrawn in 1947. No Myrsky survived intact, and since 2013 volunteers and two Finnish museums have been restoring one airframe, MY-14, for the Finnish Air Force Museum.
