The real price of Sept 11 for America

Ten years after the Sept 11, 2001, terrorist attacks on the United States, it is time to look back.

The tragic events - the crashing of two passenger jets hijacked by Al-Qaida terrorists into the World Trade Center, the collapse of the Twin Towers, the crashing of a third plane into the Pentagon, and the failed effort to crash a fourth - continue to retain a powerful hold on public consciousness.

We all remember what we were doing on 9/11, when nearly 3,000 people lost their lives. It was a day that changed the US, and the course of history, in a major way - but not for the better.
