A fiery blasts rocks the World Trade Center after being hit by two planes September 11, 2001 in New York City.
On September 11, 2001, four coordinated terrorist attacks against the United States forever changed the course of history. Four passenger airliners were hijacked by 19 al-Qaeda terrorists with the intention of flying them into landmark buildings.
American Airlines Flight 11 and United Airlines Flight 175 were flown into the North and South towers of the World Trade Center complex in New York City. American Airlines Flight 77 was crashed into the Pentagon in Arlington County, Virginia. United Airlines Flight 93 was headed toward Washington, D.C., but was crashed into a field near Shanksville, Pennsylvania after passengers overtook the hijackers. It is believed the intended target of Flight 93 was either the White House or the Capitol Building. The attacks claimed the lives of 2,996 people, including the 19 terrorists.
