KSC workers dressed in astronauts' suits climb into the slidewire baskets helped by a fire rescue team.

During a simulated rescue mission on Launch Pad 39A, known as Mode 2, KSC workers dressed in astronauts' launch-and-entry suits climb into the slidewire baskets, helped by a fire rescue team. 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/Jack Pfaller
