STS 41-B Post-Flight Presentation

Navigating the 48-mile Panama Canal that slices through the isthmus, the final shipment of a space shuttle external fuel tank emerged into the Pacific for a three-week trek to California.

This narrated footage shows the preparations that shuttle Atlantis and the mission payloads underwent at Kennedy Space Center for launch on STS-135 to the International Space Station.

A spectacle never seen before — a space shuttle external fuel tank traversing city streets — was witnessed in Los Angeles on Saturday as the relic was moved to the museum that will construct a rocket science attraction.
