HILL AIR FORCE BASE — As he wandered around the flight line with what appeared to be severe burns on his right arm, neck and face, Kevin Marshall looked like he was in shock.
All around him were other people with apparent injuries, most of them lying on the ground, screaming.
An F-16 fuselage, with smoke coming from under the downed fighter jet, sat in the middle of a circle of people pleading for help.
