Tears flowed in the White House theater Tuesday night at the conclusion of "United 93," a movie about the plane that crashed in rural Pennsylvania on Sept. 11, 2001 after passengers fought back against their hijackers.

"It was a very emotional night," said White House press secretary Tony Snow, who watched the movie with President Bush and relatives of some of the 40 passengers and crew members portrayed in the film.

"It has a very powerful ending," Snow said Wednesday. "It's dead silence as the credits roll, and you had sounds of quiet sobbing in the room."
