"That is the most graceful, beautiful vehicle we've had to fly in space, ever, and it's going to be a long time until you see a vehicle roll out to the pad that looks as beautiful as that. How can you beat that? An airplane on the side of a rocket. It's absolutely stunning."
-- Atlantis mission specialist Rex Walheim
