Engineering film footage of the final shuttle launch

A last-of-its-kind piece of space hardware — the only remaining shuttle external fuel tank — makes its way along the city streets of Los Angeles to the California Science Center.

Workers removed the protective wrap that has cocooned space shuttle Atlantis while its $100 million new home was built around it at the Kennedy Space Center Visitor Complex.

Shuttle Endeavour launched for the 25th and final time on this date in 2011.
