When the World Trade Centers fell, the tremors were felt from coast to coast. They were certainly felt in the heartland of the country where I live. Although I was terribly saddened by the hatred of those who committed this horrible cruelty, I was astonished by the heroism of the firefighters, police officers, and emergency workers who marched up the steps of the Trade Centers and regular people like Welles Crowthor, Michael Benfante, John Cerqueira, and the custodians at the Pentagon. I was deeply moved by the courage of the passengers on United Flight 73 who rose up against their captors. How many lives did they save that day?
