KENNEDY SPACE CENTER, FLA. -- Dressed in his launch and entry suit, STS-122 Pilot Alan Poindexter climbs the steps to the shuttle training aircraft, or STA, at NASA's Kennedy Space Center. Poindexter and Commander Steve Frick will practice shuttle landings in the STA before the Dec. 6 launch on space shuttle Atlantis. The STA is a Grumman American Aviation-built Gulf Stream II jet that was modified to simulate an orbiter's cockpit, motion and visual cues, and handling qualities. Photo credit: NASA/Kim Shiflett
