The Douglas DC-2 was a 14-seat, twin-engine airliner 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. With United Airlines having a monopoly on the 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 highly robust tapered wing, a retractable undercarriage, and only two 690 hp (515 kW) Wright radial engines driving variable-pitch propellers. It seated 12 passengers.

TWA accepted the basic design and ordered 20, with more powerful engines and seating for 14 passengers, as DC-2s. The design impressed a number of American and European airlines and further orders followed. Those for European customers KLM, LOT, Swissair, CLS and LAPE were assembled by Fokker in the Netherlands after that company bought a licence from Douglas. 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 actually delivered. 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 approximately $80,000 per aircraft, if mass produced.

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.

Survivors

DC-2 - c/n 1404

DC-2 - c/n 1368

There are currently no DC-2s in commercial service, however, several aircraft made it into the 21st century:

• 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 colour 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 1288: Also located at the Aviodrome in the Netherlands though owned by the Dutch Dakota Association. It is far from airworthy and will not be restored to such a condition. Its first operator was Eastern Air Lines.
• 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.
• One DC-2-115E (c/n 1354, reg. DO-1, ex. PH-AKH, SE-AKE) is preserved at the Aviation Museum of Central Finland (Finnish Air Force Museum) in Jyväskylä. The DC-2 is currently being restored to display condition (completion date estimated as September 2011). 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 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 1376 is owned by Steve Ferris in Sydney, Australia, and has been under restoration to flying status for many years.^{[citation needed]} 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 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. Removed from display late 2002 and into 2003 for preservation work.
• 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 1934 movie, Bright Eyes. A DC-2 appears in the 1937 film Lost Horizon; the footage includes taxiing, take-off, and landing, as well as views in flight.

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.
