Den Boeing modell 247 var et tidlig amerikansk passasjerfly, ansett som det første slike flyet som fullt ut inkorporerte fremskritt som semimonocoque-konstruksjon i metall (anodisert aluminium), en fullt utkraget vinge og uttrekkbart landingsutstyr. Andre avanserte funksjoner inkluderte trimfliker på kontrollflaten, en autopilot og avisingsstøvler for vingene og haleplanet.

Den Boeing 247 was a groundbreaking aircraft that introduced many innovations to the aviation industry. It was an all-metal, twin-engine airliner that could carry 10 passengers and three crew members. It had a sleek design with a fully cantilevered wing, a semimonocoque structure and retractable landing gear. It also had advanced features such as trim tabs, an autopilot, de-icing boots and variable-pitch propellers.
The Boeing 247 first flew on February 8, 1933 and entered service with Boeing Air Transport on May 22, 1933. It was faster than any fighter plane of its time and could fly on one engine if needed. The Boeing 247 set a new standard for passenger comfort and safety, and influenced the design of later airliners such as the Douglas DC-1.
