Terrorist Attack

On September 11 2001, there was a seriously terroristic attack happened in the United Stated. Four airplanes were hijacked and two of them were commanded to crash into the Twin Towers of the World Trade Center in New York City, killing everyone on board and many others working in the buildings. Both buildings collapsed and destroyed nearby buildings and damaged others. It was such a horrible scene that people would never forget. Since then, terrorist attack has become a serious issue concerned especially people in the United Stated. The U.S. government immediately tightened the airline security and ramped up the security at airports. Although, travelers and those who are going to the U.S. have to spend more time at the checkpoints, it can definitely lower the intention of terroristm and protect people from being threatened by terrorist attack.
