Lockheed Model 14 Super Electra
The Lockheed Model 14 Super Electra was a twin-engine airliner developed from the Model 10 Electra and first flown on July 29, 1937. It entered service with Northwest Airlines that October and was exported to airlines in Europe and beyond. Lockheed built 114; another 240 were built under license in Japan by Tachikawa and Kawasaki, whose Ki-56 freighter was redesigned from the type. Howard Hughes flew one around the world in 91 hours in July 1938, and Lockheed developed the airliner into the Hudson patrol bomber for wartime service.
