In the early 1930s, Boeing's 247 airplane was the airplane to beat. Donald Douglas' company secured a TWA contract for a new style of airplane. Douglas Commercial Model 1 (DC-1), was produced in 1933. The model was tinkered with and unveiled the following year. This DC-2 was successful enough to make Boeing's 247 practically obsolete. Douglas Aircraft engineers continued to tinker and improve their design. Their first DC-3 was unveiled on December 17, 1935. While not as revolutionary as the craft flown by the Wright Brothers at Kitty Hawk 32 years ago on that date, the DC-3 changed the industry.
