C-124 Globemaster II

The Douglas C-124 Globemaster II, nicknamed "Old Shaky", is a retired American 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 (USAF) Military Air Transport Service (MATS) during the 1950s and early 1960s, until the Lockheed C-141 Starlifter entered service. It served in MATS, later Military Airlift Command (MAC), and units of the Air Force Reserve and Air National Guard until retired in 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 Wasp Major 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 nurses. It was the only aircraft of its time capable of transporting fully assembled heavy equipment such as tanks and bulldozers.

The C-124 first flew on 27 November 1949, with the C-124A being delivered from May 1950. The C-124C was next, featuring more powerful engines, and an APS-42 weather radar fitted in a "thimble"-like structure on the nose. 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, for testing the Pratt & Whitney XT57 (PT5) turboprop, which was installed in the nose.Connors 2010, p. 294.

Operational history

First deliveries of the 448 production aircraft began in May 1950 and continued until 1955. The C-124 was operational during the Korean War, and was also used to assist supply operations for Operation Deep Freeze in Antarctica. They performed heavy-lift cargo operations for the U.S. military worldwide, including flights to Southeast Asia, Africa, and elsewhere. From 1959 to 1961, they transported Thor missiles across the Atlantic to England. The C-124 was also used extensively during the Vietnam War transporting materiel from the U.S. to Vietnam. Until the C-5A became operational, the C-124 and its sister C-133 Cargomaster were the only aircraft available that could transport very large loads.

The USAF's Strategic Air Command (SAC) was the initial operator of the C-124 Globemaster, with 50 in service from 1950 through 1962. Four squadrons operated the type, consisting of the 1st, 2nd, 3rd, and 4th Strategic Support Squadrons. Their primary duty was to transport nuclear weapons between air bases and to provide airlift of SAC personnel and equipment during exercises and overseas deployments.

The Military Air Transport Service (MATS) was the primary operator until January 1966, when the organization was retitled Military Airlift Command (MAC). Within a few years following the formation of MAC, the last remaining examples of the C-124 were transferred to the Air Force Reserve (AFRES) and the Air National Guard (ANG), said transfers being complete by 1970. The first ANG unit to receive the C-124C, the 165th Tactical Airlift Group (now known as the 165th Airlift Wing) of the Georgia Air National Guard, was the last Air Force unit to retire their aircraft (AF serial numbers 52-1066 and 53-0044) in September 1974.

Accidents and incidents

*23 March 1951: A C-124A 49-0244 flying from Loring Air Force Base to RAF Mildenhall reported a fire in the cargo crates, signaling mayday. They began jettisoning the crates and announced they were ditching. The C-124 ditched around , southwest of Ireland. The aircraft was intact when it touched down on the ocean. All hands exited the aircraft wearing life preservers and climbed into the inflated five-man life rafts. The rafts were equipped with cold-weather gear, food, water, flares, and Gibson Girl hand-crank emergency radios. Shortly after the men were in the life rafts, a B-29 pilot out of England spotted the rafts and the flares that the men had ignited. Their location was reported and the pilot left the scene when his fuel was getting low. No other United States or Allied planes or ships made it to the ditch site for over 19 hours, until Sunday, 25 March 1951. When the ships arrived, all they found were some charred crates and a partially deflated life raft. Ships and planes continued searching for the next several days, but not a single body was found. Some circumstantial evidence indicates that the airmen may have been "snatched" by the Soviet Union for their intelligence value, but their fate remains a mystery. See 1951 Atlantic C-124 disappearance.
*22 November 1952: C-124A 51-0107 ,flying out of McChord Air Force Base in Washington, crashed into the Colony Glacier on Mount Gannett, east of Anchorage, Alaska, killing all 41 passengers and 11 crew. Debris from the plane and remains of some of the victims were found by the Alaska National Guard on 10 June 2012, having apparently been uncovered due to the receding of the glacier. By 2014, remains of 17 victims had been recovered.
*20 December 1952: C-124 50-0100 flying out of Moses Lake, Washington ( Larson AFB), and taking airmen home to Texas for the holidays as part of "Operation Sleigh Ride" crashed not long after takeoff. In total, 87 airmen were killed.
*18 June 1953: C-124 51-137 took off from Tachikawa Air Base in Japan. Shortly after takeoff, one of the engines failed, forcing the pilot to make an emergency landing. Due to a loss of airspeed, the pilot lost control and crashed into a melon patch, killing all seven crew and 122 passengers. At the time, it was the worst accident in aviation history.
*6 April 1956: C-124 52-1078, crashed on takeoff from Travis AFB. Three of the seven crew members died in the crash. The cause of the crash was attributed to the crossing of the elevator control cables by maintenance personnel.
* 2 April 1957: C-124A 51-5176 crashed on final approach in Cambridge Bay, Nunavut (at the time, in the Northwest Territories), while ferrying supplies for the construction of the DEW Line station. No fatalities occurred, but the aircraft was damaged beyond repair.
*31 August 1957: C-124C 52-1021, operated by the 1st Strategic Squadron, crashed during an instrument approach to Biggs Air Force Base in El Paso, Texas, in bad weather after a flight from Hunter AFB near Savannah, Georgia. Five aircrew were killed, and 10 were injured.
*4 September 1957, C-124A 51-5173 ''en route'' from Larson AFB, Washington, crashed while attempting a landing at Binghamton Airport, Binghamton, New York. The C-124A was delivering 20 tons of equipment for Link Aviation. The crew of nine survived.
*27 March 1958: C-124C 52-0981 collided in midair with a USAF Fairchild C-119C Flying Boxcar, 49-0195, over farmland near Bridgeport, Texas, killing all 15 on the Globemaster and all three on the Flying Boxcar. The two transports crossed paths over a VHF omnidirectional range (VOR) navigational radio beacon during cruise flight under instrument flight rules in low visibility. The C-124 was on a north-north-easterly heading flying at its properly assigned altitude of 7,000 ft (2,100 m); the C-119 was on a southeasterly heading, and the crew had been instructed to fly at 6,000 ft (1,800 m), but their aircraft was not flying at this altitude when the collision occurred.
*16 October 1958: C-124C 52-1017 crashed into a mountain near Cape Hallett Bay, killing seven of the 13 on board. Navigational errors were made during this air-drop mission over Antarctica.
*18 April 1960: C-124C 52-1062 crashed into a hillside after taking off in heavy fog from Stephenville-Harmon Air Force Base, Newfoundland and Labrador, Canada, killing all nine on board.
*24 May 1961: C-124 51-0174 crashed following takeoff from McChord Air Force Base. Eighteen of the 22 passengers and crew were killed. M/Sgt Llewellyn Morris Chilson, the second-highest decorated soldier of World War II, was one of the four survivors.
*2 January 1964: C-124C 52–0968 of the 24th Air Transport Squadron flying from Wake Island Airfield to Hickam Air Force Base, Honolulu, was on a flight from Tachikawa Air Force Base near Tokyo, Japan, with 11 tons of cargo; the plane disappeared over the ocean, 1,200 km west of Hawaii. The Globemaster II is last heard from at 0159 hrs. An automatic SOS signal was detected emanating from an aircraft-type radio with a constant carrier frequency of 4728 kHz, issuing an automatically keyed distress message. Eight crew and one passenger were lost in the accident.Ranter, Harro and Fabian I. Lujan
