Twin Towers Fall: 9/11 Shatters American Security

Nineteen hijackers from al-Qaeda seized four commercial aircraft on the morning of September 11, 2001. American Airlines Flight 11 struck the North Tower of the World Trade Center at 8:46 a.m.; United Airlines Flight 175 hit the South Tower at 9:03 a.m. American Airlines Flight 77 crashed into the Pentagon at 9:37 a.m. Passengers on United Flight 93 learned of the other attacks through phone calls, voted to storm the cockpit, and brought the plane down in a field near Shanksville, Pennsylvania, at 10:03 a.m. The South Tower collapsed at 9:59 a.m.; the North Tower at 10:28 a.m. Nearly 3,000 people died. The attacks triggered the invasion of Afghanistan, the creation of the Department of Homeland Security, and the most extensive overhaul of American security since World War II.
