The Story Of NASA's Boeing 747 Shuttle Carrier Aircraft

NASA, the United States' Space Agency, has previously employed two modified Boeing 747 airliners in its fleet, used to transport its Space Shuttle orbiters. These two aircraft were two different variants of the Boeing 747, and were often used on different missions. Both Shuttle Carriers have been retired by NASA since 2012; however, they have both been preserved and are on display to the public.
