Introduced in 1933, the twin-engine low-wing Boeing 247, with its all-metal construction, set the pattern for successful airliners for the next 20 years. Although a good airplane, and bought by United Airlines and other U.S. carriers, its capacity proved too small and its passengers found it awkward to step over the main spar in the aisle. Although superseded by the famous Douglas DC-3 for main routes, 247s continued to operate into the 1950s with smaller airlines and private operators. Only 75 247s were built.
With a configuration consisting of an all-metal stressed skin, low cantilevered wing, retractable undercarriage, twin engines mounted on the leading edge of the wing, and variable-pitch propellers, Boeing scooped the field. The famous Douglas DC-1 and DC-2 were after-the-fact attempts to match the technical standards of the Boeing 247. It was the first airliner able to climb on one engine at full-load, one of the first with supercharged engines, and the first with control trim-tabs and cabin air-conditioning.

Donation from California Standard Oil Company, Alberta
This aircraft was manufactured as a 247 in 1934 by Boeing Aircraft Company and was converted to a 247D model in July 1935. It flew for more than ten different operators, including United Air Lines, the RCAF, Quebec Airways and Canadian Pacific Airlines. It was donated to the Museum in 1967 by its last operator, California Standard Oil of Calgary, Alberta. It is one of four complete 247s still existing; the others are located in the United States and the United Kingdom.
