Firefighters from the 628th Civil Engineer Squadron train during a controlled burn on Joint Base Charleston, S.C., Oct. 6, 2011. The squadron uses controlled burns to simulate a burning C-17 in order to prepare the men and women for future fire challenges, whether that requires physically entering a burning C-17 or from a fire truck.
