2. Summary
On September 11, 2001, 19 militants associated with
the Islamic extremist group al-Qaeda hijacked four
airliners and carried out suicide attacks against targets
in the United States. Two of the planes were flown into
the towers of the World Trade Center in New York City, a
third plane hit the Pentagon just outside Washington,
D.C., and the fourth plane crashed in a field in
Pennsylvania. Often referred to as 9/11, the attacks
resulted in extensive death and destruction, triggering
major U.S. initiatives to combat terrorism and defining
the presidency of George W. Bush. Over 3,000 people
were killed during the attacks in New York City and
Washington, D.C., including more than 400 police
officers and firefighters.

Hijackers Pass Security Screening
Hijackers Mohammed Atta and Abdulaziz al-Omari pass
through security at Portland International Jetport in
Maine. They board a shuttle flight to Boston's Logan
International Airport, where they connect to Los
Angeles-bound American Airlines Flight 11.Over the next
hour and a half, seventeen other hijackers clear security
checks at Logan Airport, Newark International Airport,
and Washington Dulles Airport. All presumably carry
knives, box cutters or other concealed weapons on their
person or in carry-on luggage. Although eight are
randomly tagged for additional screening and a gate
agent flags two as suspicious, none are prevented from
boarding their intended flights.
4. Flights Take Off
Seventy-six passengers, 11 crew members and five hijackers board

heavy," stocked with 76,400 pounds of fuel for its transcontinental
run.Al Qaeda terrorists hijack the plane at approximately 8:14 am
and reroute it towards Manhattan, using the Hudson River as a
navigational guide.Courtesy of the US Department of Justice
Fifty-one passengers, nine crew members, and five hijackers board
Los Angeles-bound Flight 175. Al Qaeda terrorists hijack the plane
at approximately 8:45 am and reroute it towards
Manhattan.Courtesy of the US Department of Justice
American Airlines Flight 77, en route to Los Angeles, departs
Washington Dulles International Airport ten minutes delayed. (8:20
am)
United Airlines Flight 93 departs Newark International Airport after a
lengthy air traffic delay on the tarmac. Flight 93 was scheduled to

flights.
5. 8:46 am
Crash of Flight 11
Hijackers crash Flight 11 into floors 93-99 of the World
Trade Center's North Tower, killing everyone on board
and hundreds within the building.
6. 9:02 am
South Tower Evacuation Order
Three minutes after initiating the evacuation of the
South Tower, the Port Authority broadcasts evacuation
orders over the Tower public adress system. An
estimated 10,000 to14,000 people are already
evacuating the World Trade Center.
Hijackers crash Flight 175 into floors 77 to 85 of the
World Trade Center's South Tower, killing everyone on
the plane and hundreds inside the building. During its
final nose dive, the plane lost altitude at a rate of
approximately 5,000 feet per minute. (9:03 am)
7. 9:15 am
Evacuation of the World Trade
Center
As first responders arrive and deploy into the stricken
buildings, tenants continue to evacuate the North and
South Towers. Hijacked Flight 11 severed all three North
Tower emergency stairwells, making evacuation
impossible for those alive on or above the impact floors.
One stairwell in the South Tower remains passable,
although it is choked with debris. Eighteen use it to
evacuate from above the impact zone.
8. 9:37 am
Crash of Flight 77
Hijackers crash Flight 77 into the Pentagon’s western
facade, killing the 59 on board the plane and 125
military and civilian personnel inside the building. A
hundred and six are severely injured in the ensuing fire.
9. 9:57 am
Fight for Flight 93
Thirteen of Flight 93's 40 passengers and crew managed
to alert loved ones and authorities to the plane’s
hijacking. At least six learn about the attacks on the
World Trade Center or the Pentagon. In response, Flight
93's passengers are believed to have collectively voted
to mount a counterattack to the hijackers.
To prevent passengers from retaking the airplane,
hijackers deliberately crash Flight 93 in a field in
Somerset County, Pennsylvania, killing the forty on
board. The crash site is approximately 20 minutes flying
time from Washington DC (10:03 am)
10. Collapsing of the Buildings

in 10 seconds, killing approximately 600 workers and
first responders in the building and surrounding area.

“The attacks of September 11th were intended to break our
spirit. Instead we have emerged stronger and more unified.
We feel renewed devotion to the principles of political,
economic, and religious freedom, the rule of law and
respect for human life. We are more determined than ever
to live our lives in freedom.”
-Rudolph Giuliani, former mayor of New York City
“You can be sure that the American spirit will prevail over
this tragedy.”
-Colin Powell
“For me and my family personally, September 11 was a
reminder that life is fleeting, impermanent, and uncertain.
Therefore, we must make use of every moment and nurture
it with affection, tenderness, beauty, creativity, and
laughter.”
