> The worst terrorist attacks in American history occurred on September 11, 2001. 2,977 people were killed. Two hijacked planes were flown into the Twin Towers at the World Trade Center. Another plane hit the Pentagon in Washington, DC. A fourth plane, Flight 93, which is thought to have been heading for the White House or the US Capitol, was diverted by passengers and eventually crashed into an empty field in Pennsylvania.
