Nineteen al-Qaeda terrorists hijacked four commercial airliners on September 11, 2001, crashing two into the World Trade Center towers in New York City, one into the Pentagon outside Washington D.C., and a fourth crashed in Pennsylvania. The attacks killed approximately 3,000 people and caused the collapse of the World Trade Center towers. It was the deadliest terrorist attack in modern history.

2. On September 11, 2001, 19 al-Qaeda-trained terrorists
hijacked four U.S. commercial airliners. The hijackers
crashed two of the jets into the World Trade Center towers
in New York City and crashed the third jet into the
Pentagon outside Washington, D.C. Passengers and crew
battled the hijackers for control of the fourth jet, and it
crashed into a field near Shanksville, Pennsylvania, short
of reaching the hijackers' intended target in Washington,
D.C.

3. The attacks caused the subsequent collapse of the
World Trade Center twin towers, damaged the
Pentagon, and killed approximately 3,000 people.
Included in the death toll were hundreds of
firefighters and rescue personnel who responded to
the crashes at the World Trade Center site and who
were in the process of rescuing those inside when
the buildings collapsed.

4. The September 11, 2001 attacks were
the most deadly international terrorist
attack in history and the largest attack
on United States territory since the
Japanese attack on Pearl Harbor on
December 7, 1941. http://hnn.us/article/874

5. "I have a sense it's a horrendous
number of lives lost. Right now
we have to focus on saving as
many lives as possible.” - Mayor
Rudolph W. Giuliani.
"These acts of mass murder
were intended to frighten
our nation into chaos and
retreat, but they have
failed," -a somber
president told the nation in
an address from the Oval
Office shortly after 8:30
p.m

8. The evacuation of the North Tower
proceeded efficiently from the time it
was hit, via the three stairways. The
elevators were all knocked out. The
102 minutes between the impact and
collapse allowed the vast majority of
its occupants below the crash zone to
escape to safety

9. “In a few locations, we came across golf
carts that were still running. It was
apparent that these common modes of
transportation around the Pentagon on
this day became escape vehicles. After
exhausting our breathing apparatus, we
were physically and mentally drained.
We returned to the outside and
immediately refilled our bottles.”

10. The 9/11 attacks on the World Trade Center
and the Pentagon were far more elaborate,
precise, and destructive than any of these
earlier assaults. But by September 2001, the
executive branch of the U.S. government,
the Congress, the news media, and the
American public had received clear warning
that Islamist terrorists meant to kill
Americans in high numbers....

11. At 8:46 a.m. on Sept. 11, 2001,
America was changed forever.
Sept. 11 victims' loved ones
will gather at ground zero to
commemorate the attacks'
anniversary with the reading
of names, moments of
silence and serene music
that have become tradition

needed help, after
the collapse of the
first World Trade
Center Tower on
Sept. 11, 2001. More
than 2,700 people
were killed when Al
Qaeda terrorists
hijacked US
passenger jets and
flew them into the
Twin Towers in New
York. Doug
