U.S. Air Force Col. David Ben, 7th Bomb Wing commander, and Chief Master Sgt. Kenneth Lindsey, 7th Bomb Wing command chief, and two Dyess firefighters extinguish a fire June 20, 2012, at the fire department training grounds on Dyess Air Force Base, Texas. Base leadership experienced firefighting from a firefighter's point of view. Training started with an exterior Jet Propellant 8 explosion, followed by an interior propane explosion in the cockpit to demonstrate the difference between the two fuel types. Firefighters are responsible for protecting Air Force assets in case of fire. Dyess Fire Department training grounds enable airmen to qualify on both propane and jet fuel.
