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.

Boeing engineers are outfitting two decommissioned space shuttle hangars at the Kennedy Space Center for the U.S. Air Force’s secretive X-37B space plane.
