The crashing from the two towers starts fires in the other buildings of the Trade Center.
Trade Center Buildings 4, 5,6, and 7 all catch aflame.
Someone tells the people in Trade Center 7 to Evacuate, sure enough, the building catches on fire and collapses as well.
Deaths are happening everywhere as people rush to get out of the buildings.
343 Firefighters were killed.
Confusion and disorder follow as 18 minutes later a second Airline hits the South tower of the World Trade Center. Now both towers are in flame. It only takes the South tower a few minutes to burn before crashing to the ground.
On a beautiful Tuesday morning in New York, at 8:45 tragedy strikes.
An American Airline, carrying passengers, crashed into the World Trade Center's north tower, killing hundreds of people instantly. The building was set aflame.
The plane hit near the 80th floor of this 110 sky scraper. This meant many people were trapped on higher floors.
This day was a tragic and terrifying day. Four passenger airlines were hacked by terrorists, in suicide attacks. All four caused much pain, death and destruction.
