During the second stage of a simulated emergency, known as Mode 4, the KSC rescue team moves "injured" astronauts, portrayed by KSC personnel, into M-113 armored carriers. The M-113 will be used to transport the workers 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
