U.S. Air Force Airman 1st Class Danny Thompson, 20th Civil Engineer firefighter, races with fellow firefighters to put on all their gear with the new M-7 Firehawk self-contained breathing apparatus at the fire station Shaw Air Force Base, S.C., Aug. 2, 2011. The new M-7 Firehawk helps Airmen complete the mission by being more durable, safer, user friendly and uses one tank instead of two. The mask has more features which include a voice enhancer and a heads up display that shows how much air is left in the tank. (U.S. Air Force photo/Airman 1st Class Tabatha L. Duarte)
