The C-5 was the largest aircraft when this film was made. The An-225 is now the heaviest and longest aircraft. The Hughes "Spruce Goose" had the widest wingspan ever. Reupload of a previously uploaded film, in one piece instead of multiple parts, and with improved sound. US Air Force film SFP-1768 Public domain film from the National Archives; aspect ratio corrected, cropped to remove uneven edges, and mild noise reduction applied. from http://www.af.mil/information/factsheets/factsheet.asp?id=84 C-5 Galaxy Features The C-5 is one of the largest aircraft in the world and the largest airlifter in the Air Force inventory. The C-5 can carry more than any other airlifter... - Able to operate on runways 6,000 feet long (1,829 meters) - Five landing gear totaling 28 wheels to distribute the weight. - Nose and aft doors that open the full width and height of the cargo compartment to permit faster and easier loading. - A "kneeling" landing gear system that permits lowering of the parked aircraft so the cargo floor is at truck-bed height or to facilitate vehicle loading and unloading. - Full width drive-on ramps at each end for loading double rows of vehicles... The C-5 has the distinctive high T-tail, 25-degree wing sweep, and four TF39 turbofan engines mounted on pylons beneath the wings. These engines are rated at 43,000 pounds of thrust each, and weigh 7,900 pounds (3,555 kilograms) each. They have an air intake diameter of more than 8.5 feet (2.6 meters). Each engine pod is nearly 27 feet long (8.2 meters). The Galaxy has 12 internal wing tanks with a total capacity of 51,150 gallons (194,370 liters) of fuel -- enough to fill 6 1/2 regular size railroad tank cars. A full fuel load weighs 332,500 pounds (150,820 kilograms). A C-5 with a cargo load of 270,000 pounds (122,472 kilograms) can fly 2,150 nautical miles, offload, and fly to a second base 500 nautical miles away from the original destination -- all without aerial refueling. With aerial refueling, the aircraft's range is limited only by crew endurance. Background Lockheed-Georgia Co. delivered the first operational Galaxy to the 437th Airlift Wing, Charleston Air Force Base, S.C., in June l970. C-5s are operated by active-duty, Reserve, and Air National Guard crews. They are currently stationed at Dover AFB, Del.; Travis AFB, Calif.; Lackland AFB, Texas; Stewart Air National Guard Base, N.Y.; Martinsburg ANGB, W.V.; Memphis ANGB, Tenn.; Wright-Patterson AFB, Ohio and Westover Air Reserve Base, Mass. In March 1989, the last of 50 C-5B aircraft was added to the 76 C-5As in the Air Force's airlift force structure. The C-5B includes all C-5A improvements as well as more than 100 additional system modifications to improve reliability and maintainability. Based on a study showing 80 percent of the C-5 airframe service life remaining, AMC began an aggressive program to modernize the C-5. The C-5 Avionics Modernization Program began in 1998... Another part of the modernization plan is a comprehensive Re-engining and Reliability Program. The centerpiece of this program is the General Electric CF6-80C2 commercial engine. This engine delivers a 22 percent increase in thrust to the C-5M, a 30 percent shorter take-off roll, has a 58 percent faster climb rate and will allow significantly more cargo to be carried over longer distances. With its new engine and upgrades, the C-5 becomes the C-5M Super Galaxy... General Characteristics Primary Function: Outsize cargo transport Prime Contractor: Lockheed-Georgia Co.
