September 11, 2001 began as another ordinary day in America.

Then the unthinkable happened.

Hijacked commercial jets bent on suicidal destruction careen into the World Trade Center in New York City, the Pentagon in the nation's capital and the rural Pennsylvania countryside.

In a matter of hours, downtown Manhattan's skyline had been forever and unforgivably altered.  America was left with two missing landmarks, thousands of innocent lives lost and a growing sense of vulnerability.

How could the incomprehensible happen and who's responsible for the madness?
