Robert Knight, 28th Maintenance Squadron aircrew egress system technician, tests contact points for of inertia reel straps on a training Advanced Concept Ejection Seat II in the egress shop during a quality check on Ellsworth Air Force Base, S.D., June 12, 2012. In the rare event of an ejection, each B-1 aircrew members would endure 12 to 14 times the downward force of gravity. The straps ensure aircrew are properly secured to the seat to avoid severe or fatal injuries. (U.S. Air Force photo by Airman 1st Class Kate Thornton/Released)
