The most iconic 747 in the world; there is no more appropriate place for this aircraft than Palmdale, California. N911NA, the second of only two Shuttle Carrier Aircraft (SCA), first flew for NASA in 1990 after being converted from a Japan Airline 747-100R. She was the second of only two SCA aircraft, initially used in 1991 to ferry the shiny new Endeavour orbiter from the Rockwell plant in Palmdale, California to Kennedy Space Center in Florida. She was based out of Palmdale, performing 66 space shuttle ferry flights.
Her final flight brought her back to Palmdale on February 8, 2012. N911NA was stored at NASA Armstrong Flight Research Center and used to spare parts for N747NA, the Stratospheric Observatory for Infrared Astronomy (SOFIA) aircraft. The Joe Davies Heritage Airpark in Palmdale, California has the honor of displaying this bird as of September 12, 2014. She will still be used as a replacement part resource for the SOFIA aircraft.
