Space shuttle Endeavour buzzes over the bay

After traveling 122.88 million miles on 25 missions to space, the space shuttle Endeavor traveled through California today on a fairwell tour to the delight of thousands of people who came out for the low-altitude flyby.

Leaving from Edwards Air Force Base in Southern California this morning, the modified 747 -- with Endeavour bolted to its back -- headed north to Sacramento, and then west towards San Francisco where it made two passes around the bay.

At NASA Ames Reseach Center in Mountain View, Calif., an estimated 20,000 people came out and for a viewing on NASA's home turf, where astronauts and engineers who had worked on Endeavor over the years were on hand to give personal accounts of their time with the shuttle.
