A crew chief assigned to the 721st Aircraft Maintenance Squadron marshals a fuel truck to refuel Air Force One, on Ramstein Air Base, Germany, Jan. 27, 2015. The 86th Logistics Readiness Squadron Airmen pumped about 500,000 pounds of fuel into the aircraft in a little more than an hour which is a record-time for the fuels team.
