The happening of 9/11/01

On September 11, 2001 a Islamic terrorist group hijacked 4 planes. The first one hit the north tower of the World Trade Center in New York City. This plane left a hole in the 80th floor of the 110 story skyscraper. The second plane hit the Pentagon in Washington Dc. 15 minutes later the third plane hit the 60th floor of the south tower of the World Trading Center in New York City,  one of the twin towers collapsed a few minutes later. The fourth plane crashed in a rural field in Western Pennsylvania, this happened because 3 passengers decided to do something about the hijackers. More than 3,000 innocent people died on 9/11 15 years ago and more than 6,000 people were injured, this day is very important because many people lost family members and friends. When i first heard about these attacks i didn't really understand why people would kill innocents civilians.
