Question: What military transport aircraft was developed from an airliner which crashed on March 27, 1951?
Context: The Douglas DC-6 is a piston-powered airliner and transport aircraft built by the Douglas Aircraft Company from 1946 to 1958.  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 commercial transport market.  More than 700 were built and many still fly today in cargo, military, and wildfire control roles. The Boeing KC-46 Pegasus is a military aerial refueling and strategic military transport aircraft developed by Boeing from its 767 jet airliner.  In February 2011, the tanker was selected by the United States Air Force (USAF) as the winner in the KC-X tanker competition to replace older KC-135 Stratotankers.  The first 18 combat-ready aircraft are scheduled to be delivered to the U.S. Air Force in early 2018 under the terms of the development contract. The Airbus A400M Atlas is a multi-national, four-engine turboprop military transport aircraft.  It was designed by Airbus Military (now Airbus Defence and Space) as a tactical airlifter with strategic capabilities to replace older transport aircraft, such as the Transall C-160 and the Lockheed C-130 Hercules.  The A400M is positioned, in terms of size, between the C-130 and the C-17; it can carry heavier loads than the C-130, while able to use rough landing strips.  Along with the transport role, the A400M can perform aerial refuelling and medical evacuation when fitted with appropriate equipment. The Hawker Siddeley HS 780 Andover is a twin-engined turboprop military transport aircraft produced by Hawker Siddeley for the Royal Air Force developed from the Avro-designed HS 748 airliner.  The Andover was named after the Avro Andover, a Royal Air Force (RAF) biplane transport used for medical evacuation between the first and second world wars; and RAF Andover, where trials of the aircraft were partially carried out.  The Andover had a kneeling landing gear to make ramp loading easier. Military transport aircraft or military cargo aircraft are typically fixed wing and rotary wing cargo aircraft which are used to airlift troops, weapons and other military equipment by a variety of methods to any area of military operations around the surface of the planet, usually outside the commercial flight routes in uncontrolled airspace.  Originally derived from bombers, military transport aircraft were used for delivering airborne forces during the Second World War and towing military gliders.  Some military transport aircraft are tasked to perform multi-role duties such as aerial refueling and, rescue missions, tactical, operational and strategic airlifts onto unprepared runways, or those constructed by engineers. The Messerschmitt Me 323 "Gigant" ("Giant") was a German military transport aircraft of World War II.  It was a powered variant of the Me 321 military glider and was the largest land-based transport aircraft of the war.  A total of 213 are recorded as having been made, a few being converted from the Me 321. The Douglas C-47 Skytrain or Dakota (RAF designation) is a military transport aircraft developed from the civilian Douglas DC-3 airliner.  It was used extensively by the Allies during World War II and remains in front line service with various military operators. The CASA/IPTN CN-235 is a medium-range twin-engined transport aircraft that was jointly developed by Construcciones Aeronáuticas SA (CASA) of Spain and Indonesian manufacturer IPTN, as a regional airliner and military transport.  Its primary military roles include maritime patrol, surveillance, and air transport.  Its largest user is Turkey which has 59 aircraft. The Antonov An-70 is a four-engine medium-range transport aircraft, and the first large aircraft to be powered by propfan engines.  It was developed in the late 1980s by the Antonov Design Bureau to replace the obsolete An-12 military transport aircraft.  However, the dissolution of the Soviet Union prevented the mass production of the type.  The maiden flight of the first prototype took place on 16 December 1994 in Kiev, now independent Ukraine.  Within a year the prototype plane had suffered a mid-air collision.  A second airframe was produced and tests continued but numerous further attempts to start production have been unsuccessful. On 27 March 1951 a Douglas Dakota 3 cargo aircraft registered "G-AJVZ" operated by Air Transport Charter en route from Ringway Airport, Manchester, England, to Nutts Corner Airport, Antrim, Northern Ireland, crashed shortly after takeoff following the failure of the aircraft to gain height.  There were two fatalities amongst the crew on board.
