Images from the terror attacks on Sept. 11, 2001
In this Wednesday, Aug. 10, 2011 picture, former Associated Press photographer, Doug Mills, currently with the New York Times, stands for a photograph in the colonnade at the White House in Washington. Sept. 11, 2001, started out like most days covering President George W. Bush on the road. It was only after Mills and other journalists boarded Air Force One and began watching the live CNN news feed that the full import of that morning's schoolroom event came into focus. A visit that had started out as a routine "photo-op," was now a moment in history. (AP Photo/Carolyn Kaster)
