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 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.
TWA accepted the basic design and ordered twenty of the upgraded DC-2s which were longer, had more powerful engines, and carried 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 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)., 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. 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. 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.
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 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 Albury racecourse on the very last leg of the journey.
- 156 civil DC-2s, variously powered by two Wright R-1820-F2 -F2A -F3 -F3A -F3B -F52 -F53 Cyclone radial piston engines varying in power from 710 to 875 hp (529 to 652 kW).

Several DC-2s have survived and been preserved in the 21st century in the following museums in the following places:
- c/n 1286 - Ex-Eastern Airlines and RAAF, preserved (dressed as the historic "Uiver", PH-AJU) at Albury, New South Wales as centerpiece of Uiver Memorial at Albury Airport. This is the oldest DC-2 left in the world. It was removed from its prominent position on poles in front of the Albury Airport terminal building in late 2002, but unfortunately kept out in the open air without preservation. In 2014 after much debate and delays, Albury City Council transferred ownership of the plane to the Uiver Memorial Community Trust (UMCT). In January 2016 UMCT began work on removing the major assemblies of the aircraft, and on 12 May 2016 the airframe was transferred to a restoration hangar. Restoration of this aircraft to static display standard is now under way.
- c/n 1288 - An Ex-Eastern Airlines and RAAF DC-2, it was exported and located for many years at the Aviodrome in the Netherlands though owned by the Dutch Dakota Association. It was transferred to the Netherlands Transport Museum in 2018 and has been externally restored for static display as KNILM DC-2 PK-AFK.
- c/n 1292 - There are three DC-2s surviving in Australia as of 2006; this aircraft, c/n 1292, is one of ten ex-Eastern Airlines DC-2s purchased and operated by the RAAF during World War II as A30-9. It is under restoration by the Australian National Aviation Museum. at Moorabbin Airport in Victoria, Australia
- c/n 1354 - One DC-2-115E (reg. DO-1 (Hanssin-Jukka), ex. PH-AKH (KLM Haan), SE-AKE) is preserved by the Aviation Museum of Central Finland (Finnish Air Force Museum) and is on display in a hangar in Tuulos, Finland. The plane was restored to display condition in 2011, in war-time colors. It performed one bombing raid in February 1940. Another wingless fuselage (c/n 1562, reg. DO-3, ex. OH-LDB "Sisu") was on display at the Finnish Aviation Museum in Vantaa. The fuselage was transported to the Aviation Museum of Central Finland in 2011, where it was used in the DO-1 restoration project.
- c/n 1368 - A former Pan Am aircraft that was used by the Douglas historical foundation until the merger with Boeing in 1997. It is now housed at the Museum of Flight in Seattle, Washington. This aircraft (N1934D) was restored to flying condition in 2007 and flown to Santa Maria, California for a new paint job. It received a TWA "The Lindbergh Line" livery and interior trim.
- c/n 1376 - Owned by Steve Ferris in Sydney, Australia, and has been under restoration to flying status for many years. It was originally delivered to KNILM in 1935. At the outbreak of World War II it was flown to Australia and was conscripted into use with the Allied Directorate of Air Transport. In 1944 it joined Australian National Airways and finished its flying career in the 1950s with Marshall Airways. It is registered as VH-CDZ. It is the most complete of all the Australian DC-2s as of 2008.
- c/n 1404 - The Aviodrome in Lelystad, the Netherlands, owns and operates one of the last flying DC-2s. This former United States Navy aircraft is painted in the Uiver's KLM color scheme and is sometimes seen in European airshows. It is registered as NC39165 since 1945, though it now also wears PH-AJU as a fictional registration to match that of the historic Uiver aircraft. The aircraft was operated by Mercer Airlines of Burbank, California, and sold in the late 1960s to Colgate Darden, who restored it in General Air Lines colors and moved it to his private airport in South Carolina.
- c/n 2702 - C-39A (Serial Number 38-515) is at the National Museum of the United States Air Force at Wright-Patterson AFB in Dayton, Ohio. The aircraft is currently in storage at the museum.
Notable appearances in media
The DC-2 was the "Good Ship Lollipop" that Shirley Temple sang about in the film Bright Eyes (1934). A DC-2 appears in the 1937 film Lost Horizon; the footage includes taxiing, takeoff, and landing, as well as views in flight.
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. 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. The real PH-AJU was lost in a crash a few months after the MacRobertson Air Race.
