The Boeing 247 took flight for the first time on February 8th, in 1933!
Up until this point, planes tended to be trimotor biplanes.
Developed in 1933, the Boeing 247 was a twin-engine, all-metal plane, and the first modern passenger airliner.
This plane was 50% faster than its competitors, entered in service with United Air Lines that same year, and was showcased at the Chicago World Fair.
The inaugural commercial May 22nd (1933) flight was a trip from San Francisco to New York - the journey was 19.5 hours long, a record time for cross-country travel! This also meant that passenger airliners could fly across the country without having to change planes or stop overnight.
