Justly labeled the first modern airliner, the Boeing 247 revolutionized air transportation when it entered service with United Air Lines in 1933. The Boeing 247 was 50 percent faster than its competitors. Its innovative design launched a new generation of commercial airliners, notably the Douglas DC-2.
