"Endeavour's Vertical Display: First Parts Lifted for California Science Center's 'Go For Stack'"

The stacking process of a NASA space shuttle has begun again after 12 years, as the aft skirts for two solid rocket boosters were moved into place at the California Science Center in Los Angeles. Over the next six months, the skirts will serve as a foundation for the rest of the space shuttle to be assembled, concluding with the mating of the winged orbiter Endeavour. The process, known as "Go For Stack," aims to create the world's only authentic ready-to-launch space shuttle stack in the Samuel Oschin Air and Space Center. The center is expected to open to the public in a few years and will display more than 100 aerospace artifacts.
