C-54 Skymaster Douglas Aircraft Transport Aircraft World War II

09 Dec C-54 Skymaster Douglas Aircraft Transport Aircraft World War II

John F. Martin was at the helm of aircraft operations. While Douglas stated that the production of its civil aircraft wouldn’t come in the way of delivering military planes, production of this new aircraft was taken over by the US Army Air Force. Douglas aircraft received military orders for aircraft (from France, Britain, and the US Armed Forces). Its legacy as a versatile and durable transport aircraft remains notable to this day. The C-54 Skymaster was a high-wing monoplane with a fully pressurized fuselage, making it one of the first mass-produced transport aircraft to feature such a capability. The war was over, but a new era in air transportation was beginning as the world took notice of the air transportation capabilities offered by the Douglas Skymaster.

• The war was over, but a new era in air transportation was beginning as the world took notice of the air transportation capabilities offered by the Douglas Skymaster.
• The Soviet military authorities defended this attack on an unarmed civilian aircraft by claiming the Air France plane was outside the air corridor at the time of attack.
• No trace of the aircraft or its occupants has ever been found.
• The crisis commenced on June 24, 1948, and it was assessed that essential supplies would need to be airlifted to the city.
• By January 1946, Pan American Airways was operating their Skymasters on transatlantic scheduled services to Europe and beyond.
• As the war began winding down, the C-54s that had originally been contracted by the airlines were released from the military and placed in commercial service.
• His rationale was that the C-54 was a safer airplane and its use would drastically reduce the accident rate on the Hump airlift.

Operational history

Skymaster could carry fifty troops, was used (for troop and cargo transportation) well beyond the end of the Great War until it was retired in 1975. The disappearance of a Douglas DC-4 Skymaster in 1950 led to the largest consecrated efforts by the US and Canada to find an aircraft that vanished in the skies. Over the years, many aircraft disappearances have baffled the world of avation.
The need for four-engine transports was so great that the War Department ordered large numbers of B-24s converted to the transport role as the C-87 Liberator Express. They were also adopted as a means of delivering dispatches and transporting high-level personnel to and from England. A new need that developed just before the war was to return Army ferry pilots to the United States from overseas delivery points.

• One of its unofficial nicknames was “Sacred Cow”, which was “a reference to the high security surrounding the aircraft and its special status”.
• On July 1, 1941, Lt. Col. Caleb Haynes took off from Bolling Field outside Washington, D.C., on the first run of the “Arnold Line,” a transoceanic military airline service.
• Shortly after the capture of Myitkyina, Brig. Gen. William H. Tunner arrived in India to take command of the India-China Wing of the ATC.
• Skymaster could carry fifty troops, was used (for troop and cargo transportation) well beyond the end of the Great War until it was retired in 1975.
• The C-54GM was built under licence by Canadair.
• Canadair produced one prototype, seventeen  North Star Mk Is, and five North Star Mk MI with Merlin 622 engines.
• The single VC-54C was President Roosevelt’s personal transport.

The Douglas C-54 Skymaster was the military version of the DC-4 airliner, and was the first truly effective four-engined transport aircraft to enter USAAF service. Overall, the Douglas C-54 Skymaster's combination of range, capacity, and reliability made it a cornerstone of post-war airlift operations and a significant contributor to global aviation history. The C-54 also saw military service in the Korean War and was eventually replaced by more modern transport aircraft in the 1960s.
The best feature of the C-54, and it was also true of the Liberator and other airplanes, was that by exercising fuel management techniques pilots could increase the airplane’s range substantially. The mission of the new ATC included ferrying of aircraft to combat units overseas as well as all air transportation not within the domain of troop carrier units. The B model also featured additional fuel capacity to increase range and entered service in the maniacasino spring of 1944. On July 1, 1941, Lt. Col. Caleb Haynes took off from Bolling Field outside Washington, D.C., on the first run of the “Arnold Line,” a transoceanic military airline service.
The aircraft had 26 personnel aboard including eleven nurses. North Korean fighter aircraft attacked airfields at Kimpo and Seoul, the South Korean capital, destroying one USAF C-54 on the ground at Kimpo Air Base. No trace of the aircraft or its occupants has ever been found. On 14 May 1948, an army transport plane flying through a rainstorm crashed in Northampton, Massachusetts, killing the three crew members aboard. It was, at the time, the deadliest aircraft crash on Newfoundland soil. On October 3, 1946, an American Overseas Airlines (AOA) Douglas C-54 aircraft named Flagship New England crashed soon after take-off from Stephenville, Newfoundland, killing all 39 people on board.

A General Order could be an award document that contains information on many servicemen. It was used for transporting troops, cargo, and medical evacuations across the Atlantic and Pacific theaters. The aircraft featured a tailwheel landing gear configuration and was typically operated by a crew of four to six members, depending on the mission profile. The DC-4 had proven itself in military service, and the type was seen as the vehicle to open up international routes to Europe and South America and across the Pacific to Hawaii and Australia. Troop carrier C-47s had begun transporting patients in New Guinea in 1942, but the advent of the C-54 allowed movement of wounded soldiers, sailors, and airmen from overseas combat zones to hospitals in the United States. Their wheel loading was such that the weight of the airplanes tore up the pierced steel planking runways that were laid down by engineers at forward locations.
This aircraft that was stylized militarily, first took to the skies on 14th February from Clover Field. The engines were later changed to four 1,450 hp Pratt & Whitney Twin Wasp (R-2000) 2SD1-G fourteen-cylinder radials (after talk with the aforementioned airlines). The aircraft was going to have a fuselage of a circular cross-section. The aircraft’s versatility, the numerous accidents it was involved in, and a couple of vanishing acts have made it an iconic aircraft of US history. Skymaster also served as the main airlift during the Korean War. During the Berlin Airlift of 1948 alone, more than 300 aircraft of this type were deployed.
The first C-54 to operate over the Pacific was an airplane that had been drawn off of the Atlantic route for a special airlift of B-24 stabilizers to Australia in response to an urgent requirement. In December 1942 ATC assumed the role of ferrying supplies from airfields in India to China, a mission that required operations at high altitudes over the eastern reaches of the Himalayas in order to avoid interception by Japanese fighters. The Douglas transports were very reliable—only three would be lost at sea during the entire war, and one of those was an intentional ditching.

These powerful engines gave the Skymaster an impressive range, allowing it to ferry substantial cargo over long distances. The C-54L was a single aircraft modified to use a different fuel system. The XC-54K was a single aircraft modified to use Wright R-1820-HD radial engines.

After World War II, the C-54 continued to serve with the USAF and other military and civilian operators around the world.
During its services, two Skymasters vanished, without a trace. At the peak of operations, 204 C-54s and 22 R5Ds with a further 110 Skymasters in training or undergoing maintenance were operating from Rhein-Main (Frankfurt) to Tempelhof (US zone) and from Fassberg to Gatow (British zone). Lieutenant Gail S. Halvorsen, a Utah native, alongside his fellow airmen, earned fame for dropping candy tied to parachutes out of their C-54 for the children of East Berlin.

The Skymaster’s Limitations

It was equipped with a state-room, three conference rooms and an electric left for the President’s wheelchair. The single VC-54C was President Roosevelt’s personal transport. 100 were built at Santa Monica and 120 at Chicago.

The aircraft were sold to airlines around the world. They also served as the main airlift during the Korean War. The C-54 was also used by the Royal Air Force, the French Air Force, and the armed forces of at least 12 other nations. With the introduction of the Tri-Service aircraft designation system in 1962, all R5Ds were re-designated C-54. 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. 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.
