Douglas DC-6
From Free net encyclopedia
Image:DC-6.jpg The Douglas DC-6 is an aircraft built by the Douglas Aircraft Company from 1946 to 1959. Originally intended as a military transport near the end of World War II, it was reworked after the war to compete with the Lockheed Constellation in the long-range piston transport market. More than 700 were built, and many still fly today in cargo, military, and wildfire control roles.
The DC-6 was known as the C-118 Liftmaster in United States Air Force service, and as the R6D in United States Navy service.

History
The United States Army Air Forces commissioned the DC-6 project as the XC-112 in 1944. The Air Force wanted an expanded version of the popular C-54 transport, with improved engines. By the time the XC-112 flew, the war was over, and the USAAF had rescinded its requirement.
Douglas converted its prototype into a civil air transport and delivered the first production DC-6 in March of 1947. However, a series of mysterious in-flight fires (including the fatal crash of United Airlines Flight 608) grounded the DC-6 fleet later that year: the cause was found to be a fuel vent located adjacent to the cabin heater intake. All DC-6's in service were modified to correct the problem, and the fleet was flying again after just four months on the ground.
Pan Am used DC-6 aircraft to inaugurate its first trans-Atlantic tourist class flights, starting in 1952.
On November 1st 1955 a time bomb exploded aboard the DC-6 killing 44 people above Longmont, Colorado.
Douglas designed three basic variants of the DC-6: the DC-6A was designed for cargo work, while the DC-6B was designed for passenger work and the DC-6C was a "convertible" aircraft that could accommodate both.
Image:Independence aircraft.png The military renewed its interest in the DC-6 during the Korean War, and commissioned a number of aircraft that later found their way into civilian service. Harry Truman's first presidential aircraft was an Air Force VC-118 called The Independence.
Many older DC-6 aircraft were replaced by the Douglas DC-7: those that survived into the Jet Age were replaced by Boeing 707 and Douglas DC-8 aircraft.
