The Douglas C-124 Globemaster II, nicknamed "Old Shaky", was a heavy-lift cargo aircraft built by the Douglas Aircraft Company in Long Beach, California. The C-124 was the primary heavy-lift transport for United States Air Force Military Air Transport Service (MATS) during the 1950s and early 1960s, until the Lockheed C-141 Starlifter entered service. It served in MATS-gained, later Military Airlift Command (MAC)-gained, units of the Air Force Reserve and Air National Guard until 1974. ==Design and development== Douglas Aircraft developed the C-124 from 1947 to 1949, from a prototype they created from a World War II–design Douglas C-74 Globemaster, and based on lessons learned during the Berlin Airlift. The aircraft was powered by four large Pratt & Whitney R-4360 piston engines producing each. The C-124's design featured two large clamshell doors and a hydraulically actuated ramp in the nose as well as a cargo elevator under the aft fuselage. The C-124 was capable of carrying of cargo, and the cargo bay featured two overhead hoists, each capable of lifting . As a cargo hauler, it could carry tanks, guns, trucks and other heavy equipment, while in its passenger-carrying role it could carry 200 fully equipped troops on its double decks or 127 litter patients and their attendants. It was the only aircraft of its time capable of transporting heavy equipment such as tanks and bulldozers without disassembly. The C-124 first flew on 27 November 1949, with the C-124A being delivered from May 1950.〔("C-124C." ) ''McCord Air Museum''.

Wingtip-mounted combustion heaters were added to heat the cabin, and enable wing and tail surface deicing. The C-124As were later equipped with these improvements. One C-124C, ''52-1069'', c/n 43978, was used as a JC-124C,〔Baugher Joe. ("USAF serials 1952." ) ''American Military Aircraft''. Retrieved 3 October 2011.〕 for testing the Pratt & Whitney XT57 (PT5) turboprop, which was installed in the nose.〔Francillon 1979, p. 470.〕〔Connors 2010, p. 294.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Douglas C-124 Globemaster II」の詳細全文を読む スポンサード リンク
