Watched like a hawk

KENNEDY SPACE CENTER, Fla. -- A crowd flocks to one of the 920th Rescue Wing's HH-60G Pave Hawk helicopters, used only a few minutes prior during an astronaut-recovery demonstration at NASA's World Space Expo, held here Nov. 1-4. Patrons spoke with crewmembers, snapped photographs and climbed on board the Pave Hawk as NASA's renown vehicle assembly building (VAB) loomed in the background. Aircraft enthusiasts, space junkies and children of all ages were among the thousands who packed the NASA causeway for the event. (U.S. Air Force photo/Staff Sgt. Paul Flipse)
