Countdown Dress Rehearsal

During a simulated pad emergency on Launch Pad 39A at NASA's Kennedy Space Center in Florida, STS-134 Mission Specialists Roberto Vittori, with the European Space Agency, front, and Michael Fincke, Pilot Greg H. Johnson, and Commander Mark Kelly make their way toward a slidewire basket that would take them to a safe bunker below the pad in an unlikely emergency situation. The emergency training while aboard space shuttle Endeavour is part of a week-long Terminal Countdown Demonstration Test.
