The Boeing 247 was a prototype for the modern airliner, for it was a clean cantilever low-wing all-metal monoplane of constructed with twin-engine powerplant, retractable landing gear, and accommodation for a pilot, copilot, stewardess and ten passengers. The design introduced a new feature for a civil transport aircraft by being equipped with pneumatic de-icing boots on leading edges of the wing, vertical, as well as, horizontal stabilizers to prevent accumulation of ice from reaching a dangerous level. The plane's top speed was about 200 mph with a cruising speed at about 133 mph.
Sixty examples of the Model 247 were ordered right off the drawing board to equipping the Boeing Air Transport System, which soon became United Air Lines! Below, is a picture of one of the few surviving and flyable museum pieces. It apparently was the aircraft from which Nick modeled his painting from.
