American flags are reflected in a memorial for Flight 93 in Shanksville, Pa. ``Let's Roll...." was said by heroic passenger Todd Beamer, as he led the charge to regain control of the jet from hijackers. The hijackers were diverting the flight, en route from Newark, NJ to San Francisco, for an apparent suicide mission on The Capitol in Washington, DC. The heroic acts of Beamer and fellow passengers ended in the plane crashing in Stony Creek Township near Shanksville, killing all 37 passengers and crew—but preventing an even more deadly attack on the nation’s capital.(AP Photo/Julie Jacobson)
