For those who lived through Sept. 11, 2001, the drama of Todd Beamer and the heroes of Flight 93 has become an essential part of many anniversary rites.

"I was trying to get as much information from him as I could, and he told me to say the Lord's Prayer with him," said Jefferson, in a transcript of her talk days later with Beamer's wife.

The details of the Flight 93 passenger revolt were soon made public -- a story of courage and sacrifice welcomed by a stunned nation.

"Todd became a hero, within 72 hours of his death," said Lisa Beamer, during a Wheaton College chapel service marking the 20th anniversary of 9/11. "I can only describe what happened next as divinely orchestrated chaos, and I do believe that.
