September 11, 2001:

19 al Qaeda members hijacked four US passenger airliners. One would hit the Pentagon in Washington, D.C., another would crash into the Pennsylvania countryside after passengers tried to take control of the plane headed towards Washington, D.C., and two would crash into the Twin Towers in New York. They are considered the most lethal terrorist attacks in history and would greatly alter anti-terror approaches around the world, as the U.S. launched the War on Terror. —FBI
