Were Pan-American Airlines, founded in1927, and Transcontinental and Western Air, otherwise known as TWA (today the letters stand for Trans World Airlines), founded in 1930 Other major American airlines already in existence The Model 247 entered service with United Air Lines, formed in 1934 from BoeingĪir Transport and two other companies, and did much to make this new giant airline a Passengers at a time when the airlines were just beginning to look for something larger. Plane's one limiting factor was that it was just slightly too small, with capacity for only 10 High altitude, rubber deicing "boots" were fitted to the wings and tail surfaces. Landing-gear units that retracted into the engine nacelles. Nacelles, the all-metal Model 247 was based on stressed-skin and semi-monocoque construction with an oval fuselage, enclosed cockpit as well as accommodation, and main Powered by a pair ofĥ50-hp (410-kW) Pratt & Whitney Wasp radial engines inside clean wing-mounted Perhaps deserved to enjoy greater commercial success than it did. The Model 247 was a remarkable airplane, and This was the B-9, the immediate predecessor of the first truly modern airliner, the Model 247, in 1932. The Monomail was a revelation, for its full use of stressed-skinĪ year later Boeing used the same design formula at a larger, twin-engined size, Low fuel consumption, a cantilever low-set wing of metal stressed-skin construction, and It was the first American plane to use a circular-section fuselage of metal monocoque construction, a neatly cowled radial engine offering good power and reliability with In 1930 Boeing produced the Model 200 Monomail, the most advanced mailplane The age of World War I aircraft and their derivatives was finally ending. Whose low drag was enhanced by subtle design details and the reduction of structural Time a remarkably efficient and economical airplane, designed as a very clean machine Profit on the contract using aircraft of its own design.
