The Douglas C-54 Skymaster is a four-engined transport aircraft used by the United States Army Air Forces in World War II and the Korean War. Like the Douglas C-47 Skytrain derived from the DC-3, the C-54 Skymaster was derived from a civilian airliner, the Douglas DC-4. Besides transport of cargo, the C-54 also carried presidents, prime ministers, and military staff. Dozens of variants of the C-54 were employed in a wide variety of non-combat roles such as air-sea rescue, scientific and military research, and missile tracking and recovery. During the Berlin Airlift it hauled coal and food supplies to West Berlin. After the Korean War it continued to be used for military and civilian uses by more than 30 countries. It was one of the first aircraft to carry the President of the United States, the first being President Franklin D. Roosevelt during World War II.
The Douglas DC-6 is a piston-powered airliner and cargo aircraft built by the Douglas Aircraft Company from 1946 to 1958. Originally intended as a military transport near the end of World War II, Douglas reworked it after the war to compete with the Lockheed Constellation in the long-range commercial transport market. Douglas built over 700, and many still fly in cargo, military, and wildfire control roles.
The Douglas DC-4 is an American four-engined (piston), propeller-driven airliner developed by the Douglas Aircraft Company. Military versions of the plane, the C-54 and R5D, served during World War II, in the Berlin Airlift and into the 1960s. From 1945, many civil airlines operated the DC-4 worldwide.

This is a list of aviation-related events from 1950:
The Avro York was a British transport aircraft developed by Avro during the Second World War. The design was derived from the Avro Lancaster heavy bomber, several sections of the York and Lancaster being identical. Due to the importance of Lancaster production, York output proceeded slowly until 1944, after which a higher priority was placed upon transport aircraft.
Buffalo Airways is a family-run airline based in Yellowknife, Northwest Territories, Canada, established in 1970. Buffalo Airways was launched by Bob Gauchie and later sold to one of his pilots, Joe McBryan. It operates charter passenger, charter cargo, firefighting, and fuel services, and formerly operated scheduled passenger service. Its main base is at Yellowknife Airport. It has two other bases at Hay River/Merlyn Carter Airport and Red Deer Regional Airport. The Red Deer base is the main storage and maintenance facility. The airline is also the subject of the History television reality series Ice Pilots NWT.
Active from 1951 to 1975, Air Viet Nam was South Vietnam's first commercial air carrier, headquartered in District 1, Saigon. Established under a decree by Chief of State Bảo Đại, the airline flew over two million passengers, throughout the Vietnam War, and until its collapse due to the Fall of Saigon.
The Canadair CL-44 was a Canadian turboprop airliner and cargo aircraft based on the Bristol Britannia that was developed and produced by Canadair in the late 1950s and early 1960s. Although innovative, only a small number of the aircraft were produced for the Royal Canadian Air Force (RCAF), and for commercial operators worldwide.
The Canadair North Star is a 1940s Canadian development, for Trans-Canada Air Lines (TCA), of the Douglas DC-4. Instead of radial piston engines used by the Douglas design, Canadair used Rolls-Royce Merlin V12 engines to achieve a higher cruising speed of 325 mph (523 km/h) compared with the 246 mph (396 km/h) of the standard DC-4. Requested by TCA in 1944, the prototype flew on 15 July 1946. The type was used by various airlines and by the Royal Canadian Air Force (RCAF). It proved to be reliable but noisy when in service through the 1950s and into the 1960s. Some examples continued to fly into the 1970s, converted to cargo aircraft.
RealTransportes Aéreos was a Brazilian airline founded in 1945. It was merged into Varig in 1961, when Varig bought the Consórcio Real-Aerovias-Nacional, of which Real was the main carrier.
Aden Airways was a subsidiary of British Overseas Airways Corporation (BOAC) based in Aden. It was in operation from 1949 to 1967.
Líneas Aéreas Suramericanas S.A.S was a cargo airline based in Bogotá, Colombia. It operated scheduled and chartered cargo flights to Latin America and the Caribbean. Its main base was El Dorado International Airport, Bogotá.
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.
The crash of Canadian Pacific Air Lines Flight 3505 occurred on 21 July 1951 when a Douglas DC-4 four-engined piston airliner registered CF-CPC of Canadian Pacific Air Lines disappeared on a scheduled flight for the United Nations from Vancouver, Canada, to Tokyo, Japan. Neither the aircraft nor the 31 passengers and six crew have been found. The incident marked the first aircraft loss during the Korean Airlift.
