Militants affiliated with extremist groups boarded
four passenger planes on September 11, 2001.
They crippled the crews shortly after takeoff, took
control of the aircraft with full cargoes of fuel, and
carried out the worst systematized suicide strikes
on American soil.
Two of the jets were intentionally flown into the
World Trade Center twin buildings in New York City,
a third plane hit the Pentagon just outside
Washington, D.C., and the fourth plane crashed
in a Pennsylvania field.
During the 9/11 terrorist attacks, about 3,000
individuals were killed. These attacks resulted in
widespread death and destruction. More than 400
police officers and firefighters were slain after
heroically racing to the scene... and into the towers
to help others that day.
