Shuttle Carrier Aircraft ferry flights generally originated at Edwards Air Force Base in California or on one occasion White Sands Space Harbor in New Mexico following missions which landed there, especially in the early days of the Space Shuttle program or when weather at the Shuttle Landing Facility (SLF) at Kennedy Space Center prevented ending missions there. Flights generally ended at the SLF. A number of flights began at Armstrong Flight Research Center following delivery of the orbiter from Rockwell International to NASA from the nearby facilities in Palmdale, California.
