Inside an M-113 armored personnel carrier, members of the KSC rescue team escort an "injured" astronaut, portrayed by a KSC worker, during the second stage of a simulated emergency, known as Mode 4. The M-113 will be used to transport the worker to a triage area. The emergency exercise began at the 195-foot level of Launch Pad 39A. The KSC rescue teams are practicing emergency procedures in the unlikely scenario of a mishap on the pad during a launch sequence. The exercises are standard training procedures to assess and prepare emergency personnel, procedures and hardware. Photo credit: NASA/Jim Grossmann
