Air Force Reserve Command pararescuemen and aircrews from the 920th Rescue Wing kicked off NASA's World Space Expo Air Show with a search-and-rescue demonstration. John Zarrella, a CNN News correspondent, acted as a downed astronaut during the demonstration which simulated a Mode 8 emergency space shuttle open-water bailout Nov 2. Reservists from the 920th RQW at Patrick Air Force Base, Fla., support every space shuttle launch as part of a joint task force in case an emergency occurs. (U.S. Air Force photo/Staff Sgt.
