The devastating day of 9/11 had taken place today 18 years ago. The terrorist attack took place at the World Trade Centre in New York City. In 2001, in the early hours of the day, the U.S commercial airplanes were hijacked by 19 men. The two planes were crashed into the towers of the World Trade Centre twin towers and another plane was crashed into the Pentagon in Washington D.C. and the last one went down to the location near Shanksville, Pa., after passengers and crew fought back against the hijackers whose actual target was most likely either the U.S Capitol or The White House. 
In the three crash locations ended up with 2,977 people dead. And several lives were lost in the terrorist attacks. Apart from those people, several celebrities too almost missed their meeting with the crashes and were safe while another had chosen to work behind the scenes to help others.
Several celebrities such as Micheal Jackson, Mark Wahlberg, Seth MacFarlane, Sarah Ferguson, Rob Lowe, Steve Buscemi, and others were saved from their meeting with the grim.
