September 11, 2001 was the day that never ended.
It was the day that terrorists hijacked three aircraft and crashed them into the World Trade Center and the Pentagon, two symbols of American freedom and society. A fourth aircraft was likely bound for Washington, D.C. and the United States Capitol building but instead crashed in a field outside Shanksville, Pennsylvania to complete the day's overall destruction.
The course of the day saw nearly 3,000 fatalities, and as the immediate number of injured casualties stretched well beyond those who perished, the fallout never stopped impacting life in America and around the world.
