On Launch Pad 39A at NASA's Kennedy Space Center in Florida, a Mode II-IV exercise is underway. Seen here are M-113 armored personnel carriers near the slidewire basked landing site. Involved in the drill are NASA fire rescue personnel, volunteers portraying astronauts with simulated injuries, helicopters and personnel from the Air Force’s 920th Rescue Wing and medical trauma teams at three central Florida hospitals. The drill allows teams to practice an emergency response at Pad 39A, including helicopter evacuation to local hospitals. The Space Shuttle Program and U.S. Air Force are conducting the emergency simulation. Photo credit: NASA/Dimitri Gerondidakis
