About This File
X-Plane 11.20+ Gasuden Koken 1.0. The Gasuden Koken (also known as the Koken-ki ) was a Japanese long-range research aircraft of the 1930s. It was built by the Tokyo Gas and Electric Industry, to break the world record for longest flight, setting a closed circuit world record of 11,651 km in March 1938. The Koken-ki was used for occasional test flights, last flying in 1939, and survived World War II only to be burned following the end of the war. A full-scale replica of the Koken-ki is on display at the Misawa Aviation And Science Museum in Misawa, Aomori. Please see the included 'Readme' file for more information. By Cynderdragon.
