Roamy here. The rollout of STS-135 was a little delayed, so I shanghaied my son into taking my picture with the astronauts. Then we ate some messy ice cream and waited some more. Bought a couple of T-shirts. The sun had sunk behind the Vehicle Assembly Building. We could see the stack, waiting for its journey out to the launchpad.
And finally, FINALLY, the last rollout of Atlantis began. The flood lights hit the vehicle, turning the orange External Tank a pale yellow and the white tiles of the orbiter incandescent.
We cheered, but it was still a bittersweet moment.
