The Douglas DC-1 was the first model of the famous DC (Douglas Commercial) commercial transport aircraft series. Although only one example of the DC-1 was produced, the design was the basis for the DC-2 and DC-3.
Development of the DC-1 can be traced back to the 1931 crash of TWA flight 599, which had suffered a structural failure of one of its wings, probably due to water which had over time seeped between the layers of the wood laminate and dissolved the glue holding the layers together
It was designed as a series prototype for TWA to compete against the revolutionary Boeing Model 247 ordered by Boeing subsidiary United Air Lines.
The DC-1 was very advanced for its day. Its fuselage was streamlined, as were its wings and engine cowlings. It featured all-metal construction and retractable landing gear. Variable-pitch propellers gave the plane remarkable takeoff and landing characteristics. With plush seats, a kitchen and a comfortable restroom, the DC-1 set a new standard for passenger comfort.
Great efforts were made to insulate the passenger compartment from the noise of the plane's engines. The plane's passenger seats were mounted on rubber supports, while the cabin was lined with noise absorbing fabric. Carpet covered the cabin floor and even the engines were mounted on rubber insulators.
