English: With its tremendous payload capability, the large C-5 Galaxy, an outsized-cargo transport, provides the Air Mobility Command intertheater airlift in support of United States national defence. The C-5 is one of the largest aircraft in the world. It can carry outsized cargo intercontinental ranges and can take off or land in relatively short distances. Ground crews can load and off load the C-5 simultaneously at the front and rear cargo openings since the nose and aft doors open the full width and height of the cargo compartment. It can also "kneel down" to facilitate loading directly from truck bed levels.
