Sailors gather for a mass casualty drill on the flight deck of the aircraft carrier USS Nimitz (CVN 68). The drill, consisting of an aircraft crash on the fantail of the ship, involved flight deck and support personnel working together to fight the casualty. Nimitz recently got under way to participate in the annual Rim of the Pacific Exercise (RIMPAC), the world's largest international maritime exercise.
