Passengers arriving from Japan of the DC-10 military-chartered flight de-boarded March 22, 2011, at Travis Air Force Base, Calif. Service members, family members and civil service employees voluntarily left Japan in efforts to assist and expedite recovery efforts in the country by reducing the demand for food, water, fuel and electricity during this national emergency while hundreds of thousands of Japanese citizens remain displaced.
