Fixing for fuel: maintainers lay ground work for aerial refueling
Airman 1st Class Alan Bounds, 22nd Maintenance Squadron fuel systems journeyman, replaces a valve inside the wing of a KC-135 Stratotanker Nov. 19, 2013, at McConnell Air Force Base, Kan. Fuel-systems Airmen work in tight spaces such as the interior sections of wings. Each section permits a different amount of work-space. (U.S Air Force photo/Airman 1st Class John Linzmeier)
