On September 11, 2001, two planes flown by al Qaeda crashed into the World Trade Center, also known as the Twin Towers, inNew York City. Al Quaeda wanted to do this because they wanted to have a widespread fear throughout the country and severely weaken the United States' in the world community. After the attack was over, many people were dead and several were missing in the rubbel of the once standing towers. They now have a 9/11 memorial in New York at ground zero of the buildings.
Here's a good 3 min 9/11 Clip worth seeing!
