Lockheed Model 14 Super Electra

The Lockheed Model 14 Super Electra was an American civil passenger and cargo aircraft built by the Lockheed Aircraft Corporation in the late 1930s, an outgrowth of the Model 10 Electra that was also developed into larger civil and military versions. A team led by Don Palmer scaled up the Electra, raising seating from 10 to 14, to compete with the Douglas DC-2 and the Boeing 247. The first Model 14 flew on 29 July 1937 piloted by Marshall Headle, early aircraft used the Pratt and Whitney Hornet engine, and the Wright Cyclone 9 was offered later. Lockheed built 114, while 119 were built under licence by Tachikawa and 121 by Kawasaki in Japan. It entered commercial service with Northwest Airlines in October 1937 and was the basis of the Lockheed Hudson light bomber. In 1938 Neville Chamberlain returned to London aboard a British Airways Model 14 after signing the Munich Agreement.
