An inflatable tub is filled with water that will be pumped into a C-130 Hercules equipped with a Modular Airborne Firefighting System at the South Carolina Technology and Aviation Center in Greenville, S.C., April 27, 2010. While responding to an actual fire, aircrews flying a MAFFS-equipped C-130 dispense a fire retardant but water is used for training purposes. (U.S. Air Force photo/Staff Sgt. Eric Harris)
