The other mainstay of aerial refueling today is the KC-10 Extender -- this one's flying a mission over Southwest Asia a few years back -- which can carry a total of more than 356,000 pounds of fuel in six tanks, almost twice as much as the KC-135, along with up to 75 people and nearly 170,000 pounds of cargo. A modification of the commercial DC-10, the KC-10 has been in service since 1981, and there are about 60 of them in the Air Force inventory.
