Lancer preparations
Senior Airman Phillip Larson runs through a preflight inspection next to a B-1 Lancer in Southwest Asia Sept. 28. The crew chief's tasks include observing the firing-up of four turbofan engines that expend a combined thrust of 120,000 pounds, enabling the long-range, multi-role bomber to fly at speeds exceeding 900 mph. Airman Larson is assigned to the 379th Aircraft Maintenance Squadron at a forward-operating base. (U.S. Air Force photo/Master Sgt. Scott Wagers)
