FBI training at Eglin
A charred piece of metal from the engine of a box truck was blasted away from the vehicle when it was detonated on the range Nov. 30, 2010, at Eglin Air Force Base, Fla. The detonation created a simulated crime scene for the FBI's Large Vehicle Post-Blast School. State and local law enforcement agencies, as well as Marine and Air Force explosive ordnance disposal technicians, attended the week-long class. (U.S. Air Force photo/Samuel King)
