World Trade Center: September 11, 2001 - September 11, 2011 | Friends of Photography

On September 11, 2001, four civil airliners were flying in the airspace over the United States; however, these four planes were hijacked by hijackers silently. When Americans were just about to start their work for the day, successive airplane crashes occurred at the World Trade Center in New York. The skyscrapers of the World Trade Center collapsed with a loud noise, turning into a pile of ruins and causing more than 3,000 people to lose their lives.
