Al Queda was a group of terrorists that was led by Osama bin laden. About 19 terrorists got into planes and crashed into the twin towers on 9/11/01. About 3,000 people were dead and at least 400 of them were polices and firefighter. A new skyscraper is being built near the former site of the twin towers. Today, many firefighter raise an American flag on zero ground once were the twin towers stood in honor of its memory!!
Not many, only the people in the planes knew what was to happen only minutes before it did happen.
