President Bush addresses the nation:

"The same Creator who names the stars also knows the names of the seven souls we mourn today. The crew of the shuttle Columbia did not return safely to Earth; yet we can pray that all are safely home."

Bush was (it seems paradoxical) both shaken and resolute during this speech, and at the end, I believe he wanted to say "God bless the United States of America" but his eyes misted after the line above and he just said "God bless....America." No lip biting, no faux empathy, just a President who has seen much too much tragedy in two short years.
