Sploid has a great reminiscence and some great photos of the Space Shuttle Carriers which NASA has recently retired the second one, carrier SCA 911. I have fond memories of standing at Disneyland on September 21, 2012 as the other shuttle carrier, NASA 905, flew over Los Angeles and Disneyland on the final “Tour of California” for the Space Shuttle Endeavour before it landed at LAX and then was towed to the California Science Center.
Check out the photos at Sploid or read more about the Shuttle carriers at NASA’s site.
