Staff Sgt. Chad Arrowsmith, a KC-135 crew chief deployed from Grand Forks Air Force Base, N.D., inspects an aircraft wheel and tire ensemble with a flashlight for higher visibility during the night at Site 6. Sergeant Arrowsmith, who works noon to midnight each day, enjoys working during the night because the sun has burned off most of the humidity and isn’t beating down on the tankers any more.
