The powerful vibrations of four engines propelling a 282,400 pound aircraft several miles above the ground hum across the cargo bay of a C-17 Globemaster III on its way to drop off much needed cargo.
Two pilots sit upstairs in the flight deck guiding the C-17 through the sky while another two rest along with the flying crew chiefs. Awake are three loadmasters, keeping an eye on the cargo bay while Airman 1st Class Kam Watt studies the loadmaster Air Force Instructions (AFI).
