Two of the four planes were flown into the towers of the World Trade Center in New York City. Within two hours of the crash, both buildings had collapsed. A third plane was then flown into the Pentagon just outside of Washington D.C. And the fourth plane crashed into a field in Pennsylvania. Passengers on the fourth plane regained control of the aircraft, but were unable to land safely, 2,996 citizens were killed during this event, including all 19 hijackers and the 227 civilians on the planes. The attacks also caused at least $10 billion in infrastructure and property damage. This event caused many other countries around the world including The United States of America, to reevaluate anti-terrorism methods and to strengthen them so this incident doesn't happen
