222-672: A trip entailed short hops in slower and shorter-range aircraft during the day, coupled with train travel overnight . Several radial engines were offered for the DC-3. Early-production civilian aircraft used either the 9-cylinder Wright R-1820 Cyclone 9 or the 14-cylinder Pratt & Whitney R-1830 Twin Wasp , but the Twin Wasp was chosen for most military versions and was also used by most DC-3s converted from military service. Five DC-3S Super DC-3s with Pratt & Whitney R-2000 Twin Wasps were built in

259-501: A very large number of civil and military operators of the DC-3/C-47 and related types, which would have made it impracticable to provide a comprehensive listing of all operators. A common saying among aviation enthusiasts and pilots is "the only replacement for a DC-3 is another DC-3". Its ability to use grass or dirt runways makes it popular in developing countries or remote areas, where runways may be unpaved. The oldest surviving DST

296-399: Is N133D, the sixth Douglas Sleeper Transport built, manufactured in 1936. This aircraft was delivered to American Airlines on 12 July 1936 as NC16005. In 2011 it was at Shell Creek Airport, Punta Gorda, Florida . It has been repaired and has been flying again, with a recent flight on 25 April 2021. The oldest DC-3 still flying is the original American Airlines Flagship Detroit (c/n 1920,

333-469: Is a propeller -driven airliner manufactured by Douglas Aircraft Company , which had a lasting effect on the airline industry in the 1930s to 1940s and World War II . It was developed as a larger, improved 14-bed sleeper version of the Douglas DC-2 . It is a low-wing metal monoplane with conventional landing gear , powered by two radial piston engines of 1,000–1,200 hp (750–890 kW). Although

370-837: Is a conversion of the DC-3/C-47. Basler refurbishes C-47s and DC-3s at Oshkosh , Wisconsin , fitting them with Pratt & Whitney Canada PT6A-67R turboprop engines, lengthening the fuselage by 40 in (1,000 mm) with a fuselage plug ahead of the wing, and some local strengthening of the airframe. South Africa-based Braddick Specialised Air Services International (commonly referred to as BSAS International) has also performed Pratt & Whitney PT6 turboprop conversions, having performed modifications on over 50 DC-3/C-47s / 65ARTP / 67RTP / 67FTPs. American Airlines inaugurated passenger service on June 26, 1936, with simultaneous flights from Newark, New Jersey and Chicago , Illinois. Early U.S. airlines like American , United , TWA , Eastern , and Delta ordered over 400 DC-3s. These fleets paved

407-611: Is estimated about 150 are still flying. "DC" stands for "Douglas Commercial". The DC-3 was the culmination of a development effort that began after an inquiry from Transcontinental and Western Airlines (TWA) to Donald Douglas . TWA's rival in transcontinental air service, United Airlines , was starting service with the Boeing 247 , and Boeing refused to sell any 247s to other airlines until United's order for 60 aircraft had been filled. TWA asked Douglas to design and build an aircraft that would allow TWA to compete with United. Douglas' design,

444-690: The 1933 DC-1 , was promising, and led to the DC-2 in 1934. The DC-2 was a success, but with room for improvement. The DC-3 resulted from a marathon telephone call from American Airlines CEO C. R. Smith to Donald Douglas, when Smith persuaded a reluctant Douglas to design a sleeper aircraft based on the DC-2 to replace American's Curtiss Condor II biplanes. The DC-2's cabin was 66 inches (1.7 m) wide, too narrow for side-by-side berths. Douglas agreed to go ahead with development only after Smith informed him of American's intention to purchase 20 aircraft. The new aircraft

481-809: The 43rd aircraft off the Santa Monica production line, delivered on 2 March 1937), which appears at airshows around the United States and is owned and operated by the Flagship Detroit Foundation. The base price of a new DC-3 in 1936 was around $ 60,000–$ 80,000, and by 1960 used aircraft were available for $ 75,000. In 2023, flying DC-3s can be bought from $ 400,000-$ 700,000. As of 2024, the Basler BT-67 with additions to handle cold weather and snow runways are used in Antarctica including regularly landing at

518-513: The DC-2 in service from Amsterdam via Batavia (now Jakarta ) to Sydney , by far the world's longest scheduled route at the time. In total, KLM bought 23 DC-3s before the war broke out in Europe. In 1941, a China National Aviation Corporation (CNAC) DC-3 pressed into wartime transportation service was bombed on the ground at Suifu Airfield in China, destroying the outer right wing. The only spare available

555-493: The DC-3 continues to fly in active commercial and military service as of 2021, eighty-six years after the type's first flight in 1935, although the number is dwindling due to expensive maintenance and a lack of spare parts. There are small operators with DC-3s in revenue service and as cargo aircraft . Applications of the DC-3 have included passenger service, aerial spraying, freight transport, military transport, missionary flying, skydiver shuttling and sightseeing. There have been

592-612: The DC-3s originally built for civil service had the Wright R-1820 Cyclone , later civilian DC-3s used the Pratt & Whitney R-1830 Twin Wasp engine. The DC-3 has a cruising speed of 207 mph (333 km/h), a capacity of 21 to 32 passengers or 6,000 lbs (2,700 kg) of cargo, and a range of 1,500 mi (2,400 km), and can operate from short runways. The DC-3 had many exceptional qualities compared to previous aircraft. It

629-480: The DST was given the designation DC-3 . No prototype was built, and the first DC-3 built followed seven DSTs off the production line for delivery to American Airlines. The DC-3 and DST popularized air travel in the United States. Eastbound transcontinental flights could cross the U.S. in about 15 hours with three refueling stops, while westbound trips against the wind took 17 + 1 ⁄ 2 hours. A few years earlier, such

703-607: The Soviet Union as the Lisunov Li-2 (4,937 aircraft). After the war, thousands of cheap ex-military DC-3s became available for civilian use. Cubana de Aviación became the first Latin American airline to offer a scheduled service to Miami when it started its first scheduled international service from Havana in 1945 with a DC-3. Cubana used DC-3s on some domestic routes well into the 1960s. Douglas developed an improved version,

740-514: The Super DC-3, with more power, greater cargo capacity, and an improved wing, but with surplus aircraft available for cheap, they failed to sell well in the civilian aviation market. Only five were delivered, three of them to Capital Airlines . The U.S. Navy had 100 of its early R4Ds converted to Super DC-3 standard during the early 1950s as the Douglas R4D-8/C-117D . The last U.S. Navy C-117

777-616: The US Navy with the designation YC-129 alongside 100 R4Ds that had been upgraded to the Super DC-3 specifications.

814-466: The airliner market, around ninety percent of airline flights on the planet were by a DC-3 or some variant. Following the war, the airliner market was flooded with surplus transport aircraft, and the DC-3 was no longer competitive because it was smaller and slower than aircraft built during the war. It was made obsolete on main routes by more advanced types such as the Douglas DC-4 and Convair 240 , but

851-519: The airlines began operating as a single commercial brand using the Avianca name. Avianca Costa Rica serves the following destinations: According to the May 31, 1973 LACSA system timetable, the airline was serving the following international destinations: This same timetable states that all international flights were being operated with British Aircraft Corporation BAC One-Eleven twin jets at this time with

888-665: The design proved adaptable and was still useful on less commercially demanding routes. Civilian DC-3 production ended in 1943 at 607 aircraft. Military versions, including the C-47 Skytrain (the Dakota in British RAF service), and Soviet- and Japanese-built versions, brought total production to over 16,000. Many continued to be used in a variety of niche roles; 2,000 DC-3s and military derivatives were estimated to be still flying in 2013; by 2017 more than 300 were still flying. As of 2023 it

925-551: The exception of the San José-San Andres Island route which was being flown with a Convair 440 propliner.

962-696: The first of their BAC One-Eleven twin-engined jet airliners onto their Caribbean passenger route network in April 1967. The airline also operated a subsidiary in the Cayman Islands , Cayman Brac Airways (CBA) Ltd., which it sold a 51% controlling interest in the late 1960s to the Cayman Islands government, which in turn used the air carrier to form Cayman Airways . LACSA served Grand Cayman for many years as an intermediate stop on its services between San José, Costa Rica and Miami. Beginning in 1998, TACA/LACSA

999-600: The help of Pan American World Airways , and started operations on June 1, 1946, using Douglas DC-3s for local services within Costa Rica, operating as an affiliate of Pan Am. The airline was designated as Costa Rica's Flag carrier in 1949 and was nationalized in 1958. LACSA operated the Douglas DC-6B four-engined piston airliner from 1960 until 1976 on their regular passenger, and eventually freight, scheduled flights to Miami International Airport. The airline introduced

Raymond over the next two years, and the prototype DST (Douglas Sleeper Transport) first flew on December 17, 1935 (the 32nd anniversary of the Wright Brothers ' flight at Kitty Hawk) with Douglas chief test pilot Carl Cover at the controls. Its cabin was 92 in (2,300 mm) wide, and a version with 21 seats instead of the 14–16 sleeping berths of

1258-479: Was fast, had a good range, was more reliable, and carried passengers in greater comfort. Before the World War II, it pioneered many air travel routes. It was able to cross the continental United States from New York to Los Angeles in 18 hours, with only three stops. It is one of the first airliners that could profitably carry only passengers without relying on mail subsidies. In 1939, at the peak of its dominance in

1295-580: Was one of the member airlines comprising the TACA Airlines alliance along with Aviateca , Nica, Isleña Airlines , and five other regional airlines. In 2008, a new fleet of Embraer 190 jets was introduced. Also in 2008 a new TACA logo was introduced, followed by a new fleet of Embraer 190 airplanes registered in Costa Rica and operated under the LACSA code. In October 2009, Avianca and TACA announced their merger plans to be completed in 2010. By May 28, 2013,

1332-514: Was retired July 12, 1976. The last U.S. Marine Corps C-117, serial 50835, was retired from active service during June 1982. Several remained in service with small airlines in North and South America in 2006. The United States Forest Service used the DC-3 for smoke jumping and general transportation until the last example was retired in December 2015. A number of aircraft companies attempted to design
