The Douglas DC-2 is a 14-passenger, twin-engined airliner that was produced by the American company Douglas Aircraft Company 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

edit

In the early 1930s, fears about the safety of wooden aircraft structures drove the US aviation industry to develop all-metal airliners. United Airlines had exclusive right to the all metal twin-engine Boeing 247; rival TWA 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.

Douglas test pilot Carl Cover flew the first test flight on May 11, 1934, of the DC-2 which was longer than the DC-1, had more powerful engines, and carried 14 passengers in a 66-inch-wide cabin. TWA was the launch customer for the DC-2 ordering twenty. The design impressed American and European airlines and further orders followed. Although Fokker had purchased a production licence from Douglas for $100,000 (about $2,224,000 in 2022) no manufacturing was done in The Netherlands. Those for European customers KLM, LOT, Swissair, CLS and LAPE purchased via Fokker in the Netherlands were built and flown by Douglas in the US, 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 (about$1,780,000 in 2022) per aircraft if mass-produced.[3]

Operational history

edit

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 the purpose-built de Havilland DH.88 racer Grosvenor House (race time 70 hours 54 minutes) and nearly three hours ahead of the Boeing 247D. During the total journey time of 90 hours, 13 min, it was in the air for 81 hours, 10 min. It won the handicap section of the race as although the DH.88 had finished first in the handicap section the regulations allowed the crew to claim only one victory. It flew KLM's regular 9,000-mile route, (a thousand miles longer than the official race route), carrying mail, 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 the Albury race course on the last leg of the journey.[4]

Military

edit

Modified DC-2s built for the United States Army Air Corps under several military designations:

 
The C-32 at Langley Field, 1937
XC-32
(DC-2-153) One aircraft, powered by two 750 hp (560 kW) Wright R-1820-25 radial piston engines, for evaluation as a 14-seat VIP transport aircraft, one built,[6] later used by General Andrews as a flying command post[7]
C-32A
Designation for 24 commercial DC-2s impressed at the start of World War II[6]
 
Douglas C-33
C-33
(DC-2-145) Cargo transport variant of the C-32 powered by two 750 hp (560 kW) Wright R-1820-25 engines, with larger vertical tail surfaces, a reinforced cabin floor and a large cargo door in the aft fuselage, 18 built[6]
 
Douglas YC-34
YC-34
(1x DC-2-173 & 1x DC-2-346) VIP transport for the secretary of war, basically similar to XC-32, later designated C-34, two built[8]
C-38
The first C-33 was modified with a DC-3-style tail section and two Wright R-1820-45 radial piston engines of 975 hp (727 kW) each. Originally designated C-33A but redesignated as prototype for C-39 variant, one built.[9]
 
Douglas C-39 transport, a militarized DC-2
C-39
(DC-2-243) 16-seat passenger variant, a composite of DC-2 and DC-3 components, with C-33 fuselage and wings and DC-3-type tail, center-section and landing gear. Powered by two 975 hp (727 kW) Wright R-1820-45 radial piston engines; 35 built.[10]
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]
 
Douglas 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

Notable appearances in media

edit

The DC-2 was the "Good Ship Lollipop" that Shirley Temple sang about in the film Bright Eyes (1934).[59] A DC-2 appears in the 1937 film Lost Horizon; the footage includes taxiing, takeoff, and landing, as well as views in flight.[60]

In the 1956 film Back from Eternity, the action centers on the passengers and crew of a DC-2, registry number N39165, which makes an emergency landing in headhunter territory in the remote South American jungle.[61] The plane, Construction Number (C/N) 1404, survives today (see #Surviving aircraft) in the color scheme of the one operated by KLM when it came second in the MacRobertson Air Race in 1934, flying a DC-2 registered in the Netherlands as PH-AJU Uiver.[62] The real PH-AJU was lost in a crash a few months after the MacRobertson Air Race.

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.
