STS-135 video: Narrated flow tapes

The museum-bound space shuttle tank is coming ashore this morning in Marina del Rey, California, for offloading from its transport barge.

The last space shuttle external tank in existence, headed from the New Orleans manufacturing plant to the California Science Center for the vertical launch pad display of the retired orbiter Endeavour, has passed through the Panama Canal.

It was 1986 and the U.S. Air Force was on the cusp of something unprecedented in human spaceflight — launching a space shuttle crew from California and paving the way for people to fly true polar missions.
