Shuttle Carrier N905NA was used to ferry the retired Space Shuttles to their respective museums. After delivering Endeavour to the Los Angeles International Airport in September 2012, the aircraft was flown to the Dryden Flight Research Facility, where NASA intended it to join N911NA as a source of spare parts for NASA’s SOFIA aircraft, but when NASA engineers surveyed N905NA they determined that it had few parts usable for SOFIA. In 2013, a decision was made to preserve N905NA and display it at Space Center Houston with the mockup shuttle Independence mounted on its back. N905NA was flown to Ellington Field where it was carefully dismantled, ferried to the Johnson Space Center in seven major pieces (a process called The Big Move), reassembled, and finally mated with the replica shuttle in August 2014. The display, called Independence Plaza, opened to the public for the first time on January 23, 2016.
