Airmen work on a C-5 Galaxy at Bagram Airfield, Afghanistan, on June 6, 2011. The C-5 is the Air Force's largest airlift aircraft. On Dec. 12, 1941, the U.S. Navy created the Naval Air Transport Service to provide logistics airlift for Navy’s fleets and “far flung” bases as well. On May 3, 1948, the Military Air Transport Service was created and aligned under the still-new U.S. Air Force. MATS later became Military Airlift Command. On June 1, 1992, Air Mobility Command activated to continue on this important airlift heritage as the Military Airlift Command inactivated. Seventy years after the attacks on Pearl Harbor, Hawaii, Air Mobility Command and mobility Airmen are still using the routes built by air mobility pioneers before and after the attacks to “answer the call.” (U.S. Air Force Photo/Master Sgt.
