If those people on Flight 93 didn't perform the most selfless act, the already horrible day could have (and most likely would have) resulted in a tragedy far beyond the scope of one additional terrorist act.
Who knows what decisions would have been made by our governing body after a hit to the White House or a different prominent location. I am sure the decisions would have been as calculated and as comprehensive, yet cooler heads were able to prevail.
Without these amazing people and their heroic actions, the world would have been a different place today almost 3 years later.
God Bless America and All the People Who held Hands "With Great Love" on 9-11 and helped us get through the day and days ahead.
