It's been 16 years since the attacks of September 11, 2001. But for millions of Americans, haunting memories of that day are still fresh, and many lives were changed forever.

On 9-11, terrorists hijacked four planes and were able to crash two of them into the World Trade Center's twin towers in New York and one into the Pentagon.

The remaining jet crashed in Pennsylvania when passengers overpowered the hijackers.
