Design and Devlopment
Development of the DC-1 can be traced back to the 1931 crash of TWA Flight 599, a Fokker F.10 Trimotor airliner in which a wing failed, probably because water had seeped between the layers of the wood laminate and dissolved the glue holding the layers together. Following the accident, the Aeronautics Branch of the U.S. Department of Commerce placed stringent restrictions on the use of wooden wings on passenger airliners. Boeing developed an answer, the 247, a twin-engined all-metal monoplane with a retractable undercarriage, but their production capacity was reserved to meet the needs of United Airlines, part of United Aircraft and Transport Corporation which also owned Boeing. TWA needed a similar aircraft to respond to competition from the Boeing 247 and they asked five manufacturers to bid for construction of a three-engined, 12-seat aircraft of all-metal construction, capable of flying 1,080 mi (1,740 km) at 150 mph (242 km/h). The most demanding part of the specification was that the airliner would have to be capable of safely taking off from any airport on TWA’s main routes (and in particular Albuquerque, at high altitude and with severe summer temperatures) with one engine non-functioning.

Donald Douglas was initially reluctant to participate in the invitation from TWA. He doubted that there would be a market for 100 aircraft, the number of sales necessary to cover development costs. Nevertheless, he submitted a design consisting of an all-metal, low-wing, twin-engined aircraft seating 12 passengers, a crew of two and a flight attendant. The aircraft exceeded the specifications of TWA even with only two engines, principally through the use of controllable pitch propellers.It was insulated against noise, heated, and fully capable of both flying and performing a controlled takeoff or landing on one engine.

Don Douglas stated in a 1935 article on the DC-2 that the first DC-1 cost $325,000 to design and build.

Operational History
Only one aircraft was produced. The prototype made its maiden flight on July 1, 1933, flown by Carl Cover. It was given the model name DC-1, derived from “Douglas Commercial”. During a half-year of testing, it performed more than 200 test flights and demonstrated its superiority over the most used airliners at that time, the Ford Trimotor and Fokker Trimotor. It was flown across the United States on February 19, 1934, making the journey in the record time of 13 hours 5 minutes.

TWA accepted the aircraft on 15 September 1933 with a few modifications (mainly increasing seating to 14 passengers and adding more powerful engines) and ordered 20 examples of the developed production model which was named the Douglas DC-2.

The DC-1 was sold to Lord Forbes in the United Kingdom in May 1938, who operated it for a few months before selling it in France in October 1938. It was then sold to Líneas Aéreas Postales Españolas (L.A.P.E.) in Spain in November 1938 and was also used by the Spanish Republican Air Force as a transport aircraft.Later operated by Iberia Airlines from July 1939 with the name Negron it force-landed at Málaga, Spain, in December 1940 and was damaged beyond repair.

Nice topic on the DC-1, but surely you could have come up with a more original title…


It is truly amazing to see how far the [Douglas Aircraft Company] ( has come from producing the DC-1 all the way up to the DC-10.


If you’re simply copy-pasting from Wikipedia (without even mentioning it…), please at least make the effort to state your personal opinion about the aircraft. The #real-world-aviation category isn’t made to be used as Wikipedia.


Adrien my personal opinion will come with starting from dc-2 and I will compare this with that

Cool series, I liked the aircraft model of the DC-1, DC-2, and DC-3.
