Visitors to Space Center Houston will soon be able to explore the big customized 747 that was used to transport the space shuttle back to Florida after each mission. Richard Allen, President and CEO of Space Center Houston says the jet will be displayed with the Shuttle Mock-up, Explorer, mounted on top. Best of all, visitors will be able to go inside both aircraft. Before all that can happen, Allen says there’s a lot of work to do. The giant jet will be taken apart and moved piece by piece from its current home at Ellington Field to its permanent home at Space Center Houston over the coming months. Once it is reassembled and “mated” with the shuttle mock-up, the aircraft will be outfitted with a variety of interactive exhibits that focus not only on the history of the U.S. Space Shuttle Program, but also on the future of manned space flight and exploration. Space Center Houston hopes to have the display ready for the public in the spring of 2015.
