NASA's Shuttle Carrier Aircraft 911's Final Flight

NASA 911, one of NASA's two modified Boeing 747 space shuttle carrier aircraft, flew its final flight Feb. 8, a short hop from NASA's Dryden Flight Research Center at Edwards Air Force Base to the Dryden Aircraft Operations Facility in Palmdale, Calif. Obtained from Japan Air Lines in 1989, it was modified and carried space shuttles 66 times on ferry flights over the next 21 years.
