Douglas DC-3

The Douglas DC-2 is a 14-seat, twin-engined airliner that was produced by the American company Douglas Aircraft Corporation starting in 1934. It competed with the Boeing 247. In 1935, Douglas produced a larger version called the DC-3, which became one of the most successful aircraft in history.

Design and development

In the early 1930s, fears about the safety of wooden aircraft structures (responsible for the crash of a Fokker Trimotor) compelled the American aviation industry to develop all-metal types. The United Aircraft and Transport Corporation had a monopoly on the Boeing 247; rival Transcontinental and Western Air issued a specification for an all-metal trimotor.

The Douglas response was more radical. When it flew on July 1, 1933, the prototype DC-1 had a robust tapered wing, retractable landing gear, and two 690 hp (515 kW) Wright radial engines driving variable-pitch propellers. It seated 12 passengers.

TWA accepted the basic design and ordered twenty DC-2s having more powerful engines and a bit more length, to carry 14 passengers in a 66-inch-wide cabin. The design impressed American and European airlines and further orders followed. Although Fokker had purchased a production licence from Douglas for $100,000, no manufacturing was done in Holland. Those for European customers KLM, LOT, Swissair, CLS and LAPE purchased via Fokker in the Netherlands were built and flown by Douglas in the USA, sea-shipped to Europe with wings and propellers detached, then erected at airfields by Fokker near the seaport of arrival (e.g. Cherbourg or Rotterdam).,[1] Airspeed Ltd. took a similar licence for DC-2s to be delivered in Britain and assigned the company designation Airspeed AS.23, but although a registration for one aircraft was reserved none were built.[2] Another licence was taken by the Nakajima Aircraft Company in Japan; unlike Fokker and Airspeed, Nakajima built five aircraft as well as assembling at least one Douglas-built aircraft.[2] A total of 130 civil DC-2s were built with another 62 for the United States military. In 1935 Don Douglas stated in an article that the DC-2 cost about $80,000 per aircraft if mass-produced.[3]

Operational history

Although overshadowed by its ubiquitous successor, it was the DC-2 that first showed that passenger air travel could be comfortable, safe and reliable. As a token of this, KLM entered its first DC-2 PH-AJU Uiver (Stork) in the October 1934 MacRobertson Air Race between London and Melbourne. Out of the 20 entrants, it finished second behind only the purpose-built de Havilland DH.88 racer Grosvenor House. During the total journey time of 90 hours, 13 min, it was in the air for 81 hours, 10 min, and won the handicap section of the race. (The DH.88 finished first in the handicap section, but the crew was by regulations allowed to claim only one victory.) It flew KLM's regular 9,000 mile route, (a thousand miles longer than the official race route), carrying mails, making every scheduled passenger stop, turning back once to pick up a stranded passenger, and even became lost in a thunderstorm and briefly stuck in the mud after a diversionary landing at Albury racecourse on the very last leg of the journey.[4]

C-41
The sole C-41 was a VIP aircraft for Air Corps Chief Oscar Westover(and his successor Hap Arnold ).Although supplied against a C-39 order it was not a DC-2 derivative but in fact a DC-3-253 fitted with two 1,200 hp (890 kW) Pratt & Whitney R-1830-21 engines. (The sole Douglas C-41A was also a VIP version of the DC-3A)[11]
The C-42.
C-42
(DC-2-267) VIP transport variant of the C-39, powered by two 1,000 hp (750 kW) Wright R-1820-53 radial piston engines, of 1,000 hp (746 kW) each, one built in 1939 for the commanding general, GHQ Air Force, plus two similarly-converted C-39s with their cargo doors bolted shut were converted in 1943.[11]
Douglas R2D-1 at Langley
R2D-1
(3x DC-2-125 & 2x DC-2-142) 710 hp (530 kW) Wright R-1820-12 powered transport similar to the XC-32, three built for the United States Navy and two for the United States Marine Corps.

Survivors

DC-2 - c/n 1404
DC-2 - c/n 1368

There are no longer DC-2s in commercial service, however, several aircraft have survived into the 21st century:

Notable appearances in media

The DC-2 was the "Good Ship Lollipop" that Shirley Temple sang about in the film Bright Eyes (1934).[49] A DC-2 appears in the 1937 film Lost Horizon; the footage includes taxiing, takeoff, and landing, as well as views in flight.[50]

Author Ernest K. Gann recounts his early days as a commercial pilot flying DC-2s in his memoir Fate Is the Hunter. This includes a particularly harrowing account of flying a DC-2 with heavy ice.
