That day -- Sept. 11, 2001 -- is seared into our national psyche.
The image of those planes flying into the Twin Towers, the towers crumbling before our eyes, the heroic stories of the firefighters who tried to rescue the occupants, the inspirational rebellion of passengers aboard United Flight 93, the ensuing wars in Afghanistan and Iraq: All of this changed who we are as a nation.
So as we approached the 10th anniversary of Osama Bin Laden's attack on America, we wanted to find a way to tell that story in all its complexity.
Kate Parry, assistant managing editor for special projects, struck upon the idea of traveling from here to ground zero, stopping along the way to capture a mosaic of stories and tales that collectively might answer the question of how we have changed.
Along with Curt Brown, a veteran reporter, and Jerry Holt, a veteran photographer, she spent many days planning how to tackle this daunting assignment.
Some of the stops seemed obvious: Shanksville, Pa., and Ground Zero. Dearborn, Mich., was picked because it has the largest population of Muslims in America.
The journalists also looked for locales where they might have some natural inroads with people.
Brown went to college with Timothy Haviland, who was working on the 96th floor of the North Tower when the first plane banked off the Hudson River and plowed into his floor; Brown planned to stop in Iowa, where Haviland's parents live.
