United Airlines Flight 175, a Boeing 767, departs Boston's Logan nonstop for Los
Angeles International Airport with 2 pilots, 7 flight attendants and 56
passengers. In standard configuration, the airplane has a 168-passenger
capacity. Fuel cap. 16,700 gals.
American Airlines Flight 11, a Boeing 767, departs Boston's Logan nonstop for
Los Angeles International Airport with 2 pilots, 9 flight attendants and 81 (or

United Airlines Flight 93, a Boeing 757, departs Newark International Airport,
NJ, nonstop for San Francisco with 2 pilots, 5 flight attendants, and 38 (or

American Airlines Flight 77, a Boeing 757, departs Washington Dulles Airport
nonstop for Los Angeles International Airport with 2 pilots, four flight
attendants and 58 passengers. Fuel cap. 11,275 gals.
Against headwinds on the flights to the West
Coast, all four airplanes were carrying heavy fuel loads.
All four airplanes are airborne before American Airlines Flight 11 turns sharply
off its planned westbound flight and heads south toward Manhattan. Shortly
before the turn, the jet's transponder is turned off. By this time, controllers
suspected something was amiss when the airplane did not respond to their
clearance to climb to 31,000 feet. One of the cockpit crew, Capt. John Ogonowski
or First Officer Thomas McGuinness, had the presence of mind to key open a
cockpit microphone, enabling ground controllers to hear the terrorists' threats
for the pilots "not to do anything foolish."
8:45 or 8:48 a.m.
Airlines Flight 11 slams into the North Tower, 1 World Trade Center. Impact area
is at floors 79-95 of the 110-story structure. Before the impact, a flight
attendant succeeded in getting a call through to the American Airlines
operations center at Dallas-Ft. Worth. She related multiple stabbings, that
hijackers stormed the cockpit; she also reported the seat number of one of the
hijackers. Elapsed flight time: about 46 minutes.
9:03 or 9:06 a.m.
Approximately 18 minutes later, United Airlines Flight 175 hits the south
tower, 2 World Trade Center, in the area of floors 63- 78. A businessman on the
flight reportedly gets off two cell phone calls to his father, in one reporting
that a flight attendant had been stabbed. Elapsed time of flight to impact:
about 49 min.
President Bush, who is reading to children in a Sarasota, Florida, classroom, is
approached by White House Chief of Staff Andrew Card, who whispers news of the
attack in the President's ear.
9:17 or 9:18 a.m.
The Federal Aviation Administration (FAA) shuts down all airports in the New
York City area.

The FAA orders the entire nationwide air traffic system shut down.
All flights at U.S. airports are stopped.
9:40 or 9:43 a.m.
Airlines Flight 77 crashes into the Pentagon. One of the building’s five sides
collapses. The Pentagon's 2-ft. thick outer walls are breached as the airplane
penetrates deep into the five concentric "rings" of the building's
structure. Elapsed time of flight: 90 minutes. The time of flight is explained
by the fact that the airplane flew westward, past West Virginia and briefly into
Kentucky before turning around and heading back to the capital.
Three targets symbolizing America's economic and
military power have been struck in the space of some 49 minutes.
Herded with other passengers, and at least one of the pilots, into the
back of the aircraft before its final plunge, those with cell phones are
ordered by the hijackers to call relatives to inform them they are about
to die. CNN reporter Barbara Olson used her cell phone to twice call her
husband's office at the Justice Department (her husband, Solicitor General
Ted Olson, argued President Bush's case before the U.S. Supreme Court during
the Florida vote- counting fiasco of the last presidential election). Understandably
declining to provide details of the conversations with his wife of just
seven weeks, Ted Olson said she described the hijackers as armed with "knife-like"
weapons. Barbara Olson's last words to her husband: "What do I tell the
pilot to do?"
Air traffic controllers notice the aircraft, with its transponder apparently
disabled, heading at high speed directly for unauthorized airspace around
the White House, and sound the alarm. The inbound plane circles tightly
270? and drops below radar coverage before plunging into the Pentagon.
Apparently the White House was the primary target, but for reasons unknown
at this stage the airplane was turned and struck what may have been its
secondary target, the Pentagon.
The White House is evacuated based on receipt of a "credible
9:50, 9:59 or 10:05 a.m.
WTC South tower collapses, its fire weakened steel skeleton
unable to support the 100,000-ton weight of the 50 stories above the section
damaged by the impact of the United Airlines 767. Although building engineers had designed
the WTC towers to withstand the impact of a Boeing 707, they had not anticipated
the raging fires fed by tons of spilled jet fuel. The steel had been insulated
to protect against an office fire, but the insulation may have been blown
or seared away when the jet struck. In any event, the structure held for
just 47 minutes before giving way.
Experts speculate that the terrorists may have had some knowledge of
civil engineering. They apparently knew that maximum damage would be wreaked
by flying into the middle sections of the buildings. Had they struck the
very highest floors, the subsequent damage might not have led to collapse.
Similarly, with the structure stronger at the lower floors to support the
weight of those above, an impact at the bottom of the building might not
have led to its collapse.
9:54 or 9:57 a.m.
President Bush departs Florida aboard Air Force One.
A passenger who locked himself in a lavatory aboard United AirlLines Flight
93 called 911 and advises that the airplane has been hijacked, and that
his call is not a hoax. Passenger Mark Bingham also used a cell phone to
contact his mother in San Francisco, saying that the plane had been commandeered
by three terrorists claiming to have a bomb. At some point in the flight,
air traffic control received a radio call from the cockpit asserting the
airplane was going to Washington, DC. Apparently the captain or first officer
had the presence of mind to leave the microphone keyed open. At 35,000
feet over Cleveland, Ohio, the sound of shots and commands to "get out
of here" were transmitted. During the course of events, passenger Tom Burnette
called his wife four times by cell phone, saying that he and two others
were going to try to overpower the hijackers.
10:00, 10:06 or
United Airlines Flight 93, a Boeing 757 en route from Newark, N.J., to San
Francisco with 38 passengers and seven crew members, hving reversed its westward
course over Cleveland, Ohio crashes just north of the
Somerset County Airport in a filed 80 miles southeast of Pittsburgh (and 85 miles northwest of the
presidential retreat at Camp David, Md.).
calls on his cell phone from a locked bathroom: “We are
being hijacked, we are being hijacked!” At this time there was concern the
plane was headed to Camp David.
The crash occurs 8 min. later, the site being described by one official as
"nothing but a big gouge in the earth and some broken trees." It is
possible that the airplane's near-90(?) plunge to the earth resulted from a
struggle between passengers and hijackers in the cockpit. Elapsed time of flight
from takeoff at Newark: about 2 hours and 5 min.

deployed into Lafayett Park across from the White House.

World Trade Center north tower collapses in
similarly spectacular fashion to South tower. Struck higher up on the
110-story structure by the American Airlines jet, vertical steel beams held in place
longer, about an hour and 45 min. in this case, before finally succumbing
in their fire-weakened state to the weight above. Witnesses described the
two buildings' collapse as a rain of concrete, blinding dust and ash, and
"thousands" of body parts. The second tower comes down on the
order established by the emergency response teams after the collapse of
the WTC South tower. Emergency command posts, triage centers, etc., are
destroyed by falling debris, presenting a major setback for emergency

Afghanistan is believed to be where bin Laden, who U.S. officials say is possibly behind Tuesday's deadly attacks, is located. U.S. officials say later that the United States had no involvement in the incident whatsoever. The attack is credited to the Northern Alliance, a group fighting the Taliban in the country's ongoing civil war.
