On September 11, 2001, nineteen men affiliated with al-Qaeda hijacked four commercial passenger jets all bound for California, crashing two of them into the World Trade Center in New York City, the third into the Pentagon in Arlington County, Virginia, and the fourth (originally intended to target Washington, D.C., either the White House or the U.S. Capitol) into an open field near Shanksville, Pennsylvania, after a revolt by the plane's passengers. As a result of the attacks, 2,996 people (including the 19 hijackers) perished and more than 6,000 others were injured.
