The Boeing 247 was an early modern passenger airliner. Its first flight was on February 8, 1933 and entered service that same year. The aircraft incorporated many revolutionary features such as an all-metal monocoque fuselage, autopilot, a cantilevered wing, retractable landing gear, NACA cowlings for engines, trim tabs on control surfaces, variable pitch propellers, and deicing boots for the wings and tail.

This revolutionary design combined speed and safety. It was faster than the fighter aircraft of its day. In addition, it was the first twin engine passenger aircraft that could fly on just one engine. The combination of features became the standard list for all subsequent passenger aircraft. Although engines and aircraft became ever larger, no additional features became passenger aircraft standards until pressurized cabins were introduced in the late 1940's.
