About the B-247
In 1933 The Boeing Model 247 ushered in a new era in commercial flight with its all-metal construction, setting the pattern for successful airliners for the next 20 years. Up to this point airliners were small, unreliable and relatively inefficient. The Model 247 is considered the first modern passenger airliner. The many new innovative features included an all-metal skin, two engines for greater reliability and power, it had an autopilot, low cantilevered wing, a variable-pitch constant speed propeller, pneumatically operated de-icing equipment, and retractable landing gear. It was the first airliner able to climb on one engine at full-load, the first with supercharged engines, and the first with control trim-tabs and cabin air-conditioning.
Although it took the Boeing 247 20 hours to fly the continental distance between New York and Los Angeles (including seven refueling stops), it was still seven and a half hours shorter traveling time than that made by any previous airliner. It could fly at an astonishing speed at 189 mph, making it the fastest commercial airliner at the time.
It was a good airplane, and although it was bought by United Aircraft Corporation (United Airlines) and other carriers, its capacity proved too small and it never really caught on. Of the seventy-six 247s that were built, Boeing Air Transport operated 60 of the Model 247s. United Aircraft Corporation ordered 10, and the remaining numbers went to Deutsche Lufthansa and a private owner in China. The 247s remained in airline service until World War II, when several were converted into C-73 transports and trainers. Some were still flying in the late 1960s. Along with the Douglas DC-2 that supplanted it, and the Douglas
, the Model 247 brought new standards of speed, reliability, safety, and comfort in air travel.
