9/11 Commission's Summary of the Hijacked Flights
NewsMax.com Wires
Thursday, June 17, 2004
Here is a part one of the summary of the flights of the four
planes that were hijacked on Sept. 11, 2001, as compiled by the
commission investigating the attacks:
American Airlines Flight 11
FAA Awareness:
At 8:00 a.m. on Sept. 11, 2001, American Airlines Flight 11
began its takeoff roll at Logan Airport in Boston. A Boeing 767,
Flight 11 was bound for Los Angeles with 81 passengers, 11 crew,
and 24,000 gallons of jet fuel. By 8:09 a.m., it was being
monitored by FAA's Boston Center (located in New Hampshire). At
8:13 a.m., the controller instructed the flight to "turn twenty
degrees right," which the flight acknowledged. This was the last
transmission to which the flight responded.
Sixteen seconds later, the controller instructed the flight to
climb to 35,000 feet. When there was no response, the controller
repeated the command seconds later, and then tried repeatedly to
raise the flight. He used the emergency frequency to try to reach
the pilot. Though there was no response, he kept trying to contact
the aircraft.
At 8:21 a.m., American 11 turned off its transponder,
immediately degrading the available information about the aircraft.
The controller told his supervisor that he thought something was
seriously wrong with the plane. At this point, neither the
controller nor his supervisor suspected a hijacking. The supervisor
instructed the controller to follow standard operating procedures
for handling a "no radio" aircraft.
The controller checked to see if American Airlines could
establish communication with American 11. He became even more
concerned as its route changed, moving into another sector's
airspace. Controllers immediately began to move aircraft out of its
path, and searched from aircraft to aircraft in an effort to have
another pilot contact American 11. At 8:24:38, the following
transmission came from American 11:
AMERICAN 11: We have some planes. Just stay quiet, and you'll be
O.K. We are returning to the airport.
The controller only heard something unintelligible; he did not
hear the specific words "we have some planes." Then the next
transmission came seconds later:
AMERICAN 11: Nobody move. Everything will be O.K. If you try to
make any moves, youll endanger yourself and the airplane. Just stay
quiet.
Hearing that, the controller told us he then knew it was a
hijacking. The controller alerted his supervisor, who assigned
another controller to assist him, and redoubled efforts to
ascertain the flight's altitude. Because the controller didn't
understand the initial transmission, the Manager of Boston Center
instructed the center's Quality Assurance Specialist to "pull the
tape" of the radio transmission, listen to it closely, and report
back.
Between 8:25 a.m. and 8:32 a.m., in accordance with the FAA
protocol, Boston Center managers started notifying their chain of
command that American 11 had been hijacked. At 8:28 a.m., Boston
Center called the Command Center in Herndon, Va. to advise
management that it believed American 11 had been hijacked and was
heading toward New York Center's airspace. By this point in time,
American 11 had taken a dramatic turn to the south. At 8:32 a.m.,
the Command Center passed word of a possible hijacking to the
Operations Center at FAA headquarters. The duty officer replied
that security personnel at headquarters had just begun discussing
the hijack situation on a conference call with the New England
Regional office.
The Herndon Command Center immediately established a
teleconference between Boston, New York, and Cleveland Centers so
that Boston Center could help the others understand what was
happening.
At 8:34 a.m., the Boston Center controller received a third
transmission from American 11:
AMERICAN 11: Nobody move please. We are going back to the
airport. Don't try to make any stupid moves.
In the succeeding minutes, controllers were attempting to
ascertain the altitude of the southbound Flight 11.
Military Notification and Response:
Boston Center did not follow the routine protocol in seeking
military assistance through the prescribed chain of command. In
addition to making notifications within the FAA, Boston Center took
the initiative, at 8:34 a.m., to contact the military through the
FAA's Cape Cod facility. They also tried to obtain assistance from
a former alert site in Atlantic City, unaware it had been phased
out. At 8:37:52 a.m., Boston Center reached NEADS. This was the
first notification received by the military at any level that
American 11 had been hijacked:
FAA: Hi. Boston Center TMU, we have a problem here. We have a
hijacked aircraft headed towards New York, and we need you guys to,
we need someone to scramble some F-16s or something up there, help
us out.
NEADS: Is this real-world or exercise?
FAA: No, this is not an exercise, not a test.
NEADS promptly ordered to battle stations the two F-15 alert
aircraft at Otis Air Force Base, about 153 miles away from New York
City. The air defense of America began with this call.
At NEADS, the reported hijacking was relayed immediately to
Battle Commander Colonel Robert Marr. After ordering the Otis
fighters to battle stations, Colonel Marr phoned Major General
Larry Arnold, commanding General of the First Air Force and the
Continental Region. Marr sought authorization to scramble the Otis
fighters. General Arnold instructed Marr "to go ahead and scramble
the airplanes, and wed get permission later." General Arnold then
called NORAD headquarters to report.
F-15 fighters were ordered scrambled at 8:46 a.m. from Otis Air
Force Base. But NEADS did not know where to send the alert fighter
aircraft: "I don't know where I'm scrambling these guys to. I need
a direction, a destination." Because the hijackers had turned off
the planes transponder, NEADS personnel spent the next minutes
searching their radar scopes for the elusive primary radar return.
American 11 impacted the World Trade Centers North Tower at 8:46:40
a.m. Shortly after 8:50 a.m., while NEADS personnel were still
trying to locate American 11, word reached them that a plane had
hit the World Trade Center.
Radar data show the Otis fighters were airborne at 8:53 a.m..
Lacking a target, they were vectored toward military controlled
airspace off the Long Island coast. To avoid New York area air
traffic and uncertain about what to do, the fighters were brought
down to military air space to "hold as needed." From 9:08 a.m. to
9:13 a.m., the Otis fighters were in this holding pattern.
In summary, NEADS received notice of the hijacking nine minutes
before it impacted the north tower. The nine minutes notice was the
most the military would receive that morning of any of the four
hijackings.
United Airlines Flight 175
FAA Awareness:
United Airlines Flight 175, a Boeing 767 carrying 65 passengers
from Boston to Los Angeles, took off from Logan Airport at 8:14
a.m. At 8:37 a.m. Boston Center polled United 175, along with other
aircraft, about whether they had seen an "American 767" (American
11), and United 175's pilots said they had seen it. The controller
turned United 175 away from it as a safety precaution.
At 8:41 a.m., United 175 entered New York Center's airspace. The
controller responsible for United 175 was unfortunately the same
controller assigned the job of tracking the hijacked American 11.
At 8:47 a.m., at almost the same time American 11 crashed into the
North Tower, United 175's assigned transponder code changed, then
changed again. These changes were not noticed for several minutes,
because the controller was focused on finding American 11, which
had disappeared. At 8:48 a.m., a New York Center manager provided
the following report on a Command Center teleconference about
American 11, including information that had been relayed by the
airline:
MANAGER, NEW YORK CENTER: Okay. This is New York Center. We're
watching the airplane. I also had conversation with American
Airlines, and they've told us that they believe that one of their
stewardesses was stabbed and that there are people in the cockpit
that have control of the aircraft, and that's all the information
they have right now.
The New York Center controller and manager were unaware that
American 11 had already crashed.
At 8:51 a.m., the controller noticed the change in the
transponder reading from United 175. The controller asked United
175 to go back to the proper code. There was no response. Beginning
at 8:52 a.m., the controller made repeated attempts to reach the
crew of United 175. Still no response. The controller checked that
his radio equipment was working and kept trying to reach United
175. He contacted another controller at 8:53 a.m., and worried that
"we may have a hijack" and that he could not find the aircraft.
Another commercial aircraft in the vicinity then radioed in with
"reports over the radio of a commuter plane hitting the World
Trade Center." The controller spent the next several minutes
handing off the other flights on his scope to other controllers and
moving aircraft out of the way of the unidentified aircraft
(believed to be United 175) as it moved southwest and then turned
northeast toward New York City. At approximately 8:55 a.m., the
controller-in-charge notified a New York Center manager that she
believed United 175 had also been hijacked. The manager tried to
notify the regional managers and was told that the managers were
discussing a hijacked aircraft (presumably American 11) and refused
to be disturbed. At 8:58 a.m., the New York Center controller
searching for United 175 told another New York controller "we
might have a hijack over here, two of them."
Between 9:01 a.m. and 9:02 a.m., a manager from New York Center
told the Command Center in Herndon:
MANAGER, NEW YORK CENTER: We have several situations going on
here. It's escalating big, big time. We need to get the military
involved with us . . . . We're, we're involved with something else,
we have other aircraft that may have a similar situation going on
here. . . .
The "other aircraft" New York Center referred to was United
175. Evidence indicates that this conversation was the only notice
received prior to the second crash by either FAA headquarters or
the Herndon Command Center that there was a second hijack. While
Command Center was told about this "other aircraft" at 9:01 a.m.,
New York Center contacted New York terminal approach control and
asked for help in locating United 175.
TERMINAL: I got somebody who keeps coasting but it looks like
he's going into one of the small airports down there.
CENTER: Hold on a second. I'm trying to bring him up here and
get you ... there he is right there. Hold on.
TERMINAL: Got him just out of 9,5009,000 now.
CENTER: Do you know who he is?
TERMINAL: We're just, we just we don't know who he is. We're
just picking him up now.
CENTER (at 9:02 am.): Alright. Heads up man, it looks like
another one coming in.
The controllers observed the plane in a rapid descent; the radar
data terminated over lower Manhattan. At 9:03:02 a.m., United 175
crashed into the South Tower. Meanwhile, a manager from Boston
Center reported that they had deciphered what they had heard in one
of the first hijacker transmissions from American 11:
BOSTON CENTER: Hey you still there?
NEW ENGLAND REGION: Yes, I am.
BOSTON CENTER: I'm gonna reconfirm with, with downstairs, but
the, as far as the tape seemed to think the guy said that "we have
planes." Now, I don't know if it was because it was the accent, or
if there's more than one, but I'm gonna, I'm gonna reconfirm that
for you, and I'll get back to you real quick. Okay?
NEW ENGLAND REGION: Appreciate it.
UNIDENTIFIED FEMALE VOICE: They have what?
BOSTON CENTER: Planes, as in plural.
BOSTON CENTER: It sounds like, we're talking to New York, that
there's another one aimed at the World Trade Center.
NEW ENGLAND REGION: There's another aircraft?
BOSTON CENTER: A second one just hit the Trade Center.
NEW ENGLAND REGION: Okay. Yeah, we gotta get ... we gotta alert
the military real quick on this.
Boston Center immediately advised the New England Region that it
was going to stop all aircraft scheduled to depart from any airport
within Boston Center. At 9:05 a.m., Boston Center confirmed for
both FAA Command Center and New England Region that the hijackers
aboard American 11 said "we have planes." At the same time, New
York Center declared "ATC zero" meaning that aircraft were not
permitted to depart from, arrive at, or travel through New York
Center's airspace until further notice. Within minutes of the
second impact, Boston Center's Operations Manager instructed all
air traffic controllers in his center to use the radio frequencies
to inform all aircraft in Boston Center of the events unfolding in
New York and to advise aircraft to heighten cockpit security.
Boston Center asked Herndon Command Center to issue a similar
cockpit security alert to all aircraft nationwide. We have found no
evidence to suggest that Command Center managers instructed any
Centers to issue a cockpit security alert.
Military Notification and Response:
The first indication that the NORAD air defenders had of the
second hijacked aircraft, United 175, came in a phone call from New
York Center to NEADS at 9:03 a.m. The notice came in at about the
time the plane was hitting the South Tower. At 9:08 a.m., the
Mission Crew Commander at NEADS learned of the second explosion at
the World Trade Center and decided against holding the fighters in
military air space away from Manhattan:
MISSION CREW COMMANDER, NEADS: This is what I foresee that we
probably need to do. We need to talk to FAA. We need to tell 'em if
this stuff is gonna keep on going, we need to take those fighters,
put 'em over Manhattan. That's best thing, that's the best play
right now. So coordinate with the FAA. Tell 'em if there's more out
there, which we don't know, let's get 'em over Manhattan. At least
we got some kind of play.
The FAA cleared the air space. The Otis fighters were sent to
Manhattan. A Combat Air Patrol was established over the city at
9:25 a.m.
Because the Otis fighters had expended a great deal of fuel in
flying first to military airspace and then to New York, the battle
commanders were concerned about refueling. NEADS considered
scrambling alert fighters from Langley Air Force Base in Virginia
to New York, to provide back-up. The Langley fighters were placed
on battle stations at 9:09 a.m. NORAD had no indication that any
other plane had been hijacked. The following is a time lapsed
depiction of the flight paths of American 11 and United 175. (Video
image shown.)
American Airlines Flight 77
FAA Awareness:
American 77 began its takeoff roll from Dulles International
Airport at 8:20 a.m. The flight was handed off routinely from
Washington Center to Indianapolis Center at approximately 8:40 a.m.
American 77 was acknowledged by the Indianapolis controller, who
had 14 other planes in his sector at the time. The controller
instructed the aircraft to climb and, at 8:50 a.m., cleared it to
its next navigational aid. American 77 acknowledged. This was the
last transmission from American 77.
At 8:54 a.m., American 77 began deviating from its flight plan,
first with a slight turn toward the south. Two minutes later it
disappeared completely from Indianapolis radar. The controller
tracking American 77 told us he first noticed the aircraft turning
to the southwest, and then saw the data disappear. The controller
looked for primary radar returns. He searched along its projected
flight path and the airspace to the southwest where it had started
to turn. No primary targets appeared. He tried the radios, first
calling the aircraft directly, then the airline. Again there was
nothing. At this point, the Indianapolis controller had no
knowledge of the situation in New York. He did not know that other
aircraft had been hijacked. He believed American 77 had experienced
serious electrical and/or mechanical failure, and was gone.
Shortly after 9:00 a.m., Indianapolis Center started notifying
other agencies that American 77 was missing and had possibly
crashed. At 9:08 a.m., Indianapolis Center contacted Air Force
Search and Rescue at Langley Air Force Base in Virginia, and told
them to look out for a downed aircraft. They also contacted the
West Virginia State Police, and asked whether they had any reports
of a downed aircraft. At 9:09 a.m., they reported the loss of
contact to the FAA regional center, which passed this information
to FAA headquarters at 9:24 a.m.. By 9:20 a.m., Indianapolis Center
learned that there were other hijacked aircraft in the system, and
began to doubt their initial assumption that American 77 had
crashed. A discussion of this concern between the manager at
Indianapolis and the Command Center in Herndon prompted the Command
Center to notify some FAA field facilities that American 77 was
lost. By 9:21 a.m., the Command Center, some FAA field facilities,
and American Airlines had started to search for American 77. They
feared it had been hijacked. At 9:25 a.m., the Command Center
advised FAA headquarters that American 77 was lost in Indianapolis
Center's airspace, that Indianapolis Center had no primary radar
track, and was looking for the aircraft.
The failure to find a primary radar return for American 77 led
us to investigate this issue further. Radar reconstructions
performed after 9/11 reveal that FAA radar equipment tracked the
flight from the moment its transponder was turned off at 8:56 a.m.
But for eight minutes and 13 seconds, between 8:56 a.m. and 9:05
a.m., this primary radar information on American 77 was not
displayed to controllers at Indianapolis Center. The reasons are
technical, arising from the way the software processed radar
information, as well as from poor primary radar coverage where
American 77 was flying.
According to the radar reconstruction, American 77 re-emerged as
a primary target on Indianapolis Center radar scopes at 9:05 a.m.,
east of its last known position. The target remained in
Indianapolis Center's airspace for another six minutes, then
crossed into the western portion of Washington Center's airspace at
9:10 a.m. As Indianapolis Center continued searching for the
aircraft, two managers and the controller responsible for American
77 looked to the west and southwest along the flight's projected
path, not east, where the aircraft was now heading. The managers
did not instruct other controllers at Indianapolis Center to turn
on their primary radar coverage to join in the search for American
77.
In sum, Indianapolis Center never saw Flight 77 turn around. By
the time it reappeared in primary radar coverage, controllers had
either stopped looking for the aircraft because they thought it had
crashed or were looking toward the west. In addition, while the
Command Center learned Flight 77 was missing, neither it nor FAA
headquarters issued an "all points bulletin" to surrounding
centers to search for primary radar targets. American 77 traveled
undetected for 36 minutes on a course heading due east for
Washington, D.C.
By 9:25 a.m., FAA's Herndon Command Center and FAA headquarters
knew the following. They knew two aircraft had crashed into the
World Trade Center. They knew American 77 was lost. They knew that
a hijacker on board American 11 had said "we have some planes,"
and concerns over the safety of other aircraft began to mount. A
manager at the Herndon Command Center asked FAA headquarters if
they wanted to order a "nationwide ground stop." While executives
at FAA headquarters discussed it, the Command Center went ahead and
ordered one anyway at 9:25 a.m..
The Command Center kept looking for American 77. At 9:21 a.m.,
it advised the Dulles terminal control facility, which urged its
controllers to look for primary targets. At 9:32 a.m., they found
one. Several of the Dulles controllers "observed a primary radar
target tracking eastbound at a high rate of speed" and notified
Reagan Airport. FAA personnel at both Reagan and Dulles airports
notified the Secret Service. The identity or aircraft type was
unknown.
Reagan Airport controllers then vectored an unarmed National
Guard C-130H cargo aircraft, which had just taken off en route to
Minnesota, to identify and follow the suspicious aircraft. The
C-130H pilot spotted it, identified it as a Boeing 757, attempted
to follow its path, and at 9:38 a.m., seconds after impact,
reported to Washington Tower: "looks like that aircraft crashed
into the Pentagon sir."
Military Notification and Response:
NORAD did not know about the search for American 77. Instead,
they heard once again about a plane that no longer existed,
American 11. At 9:21 a.m., NEADS received a report from the FAA:
FAA: Military, Boston Center. I just had a report that American
11 is still in the air, and it's on its way towards, heading
towards Washington.
NEADS: Okay. American 11 is still in the air?
FAA: Yes.
NEADS: On its way towards Washington?
FAA: That was another ... it was evidently another aircraft that
hit the tower. That's the latest report we have.
NEADS: Okay.
FAA: I'm going to try to confirm an ID for you, but I would
assume he's somewhere over, uh, either New Jersey or somewhere
further south.
NEADS: Okay. So American 11 isn't the hijack at all then, right?
FAA: No, he is a hijack.
NEADS: He ... American 11 is a hijack?
FAA: Yes.
NEADS: And he's heading into Washington?
FAA: Yes. This could be a third aircraft.
The mention of a "third aircraft" was not a reference to
American 77. There was confusion at that moment in the FAA. Two
planes had struck the World Trade Center, and Boston Center had
heard from FAA headquarters in Washington that American 11 was
still airborne. We have been unable to identify the source of this
mistaken FAA information.
The NEADS technician who took this call from the FAA immediately
passed the word to the Mission Crew Commander. He reported to the
NEADS Battle Commander:
MISSION CREW COMMANDER, NEADS: Okay, uh, American Airlines is
still airborne. Eleven, the first guy, he's heading towards
Washington. Okay? I think we need to scramble Langley right now.
And I'm gonna take the fighters from Otis, try to chase this guy
down if I can find him.
The Mission Crew Commander at NEADS issued an order at 9:23
a.m.: "Okay scramble Langley. Head them towards the Washington
area." That order was processed and transmitted to Langley Air
Force Base at 9:24 a.m., and radar data show the Langley fighters
were airborne at 9:30 a.m.
NEADS decided to keep the Otis fighters over New York. The
heading of the Langley fighters was adjusted to send them to the
Baltimore area. The Mission Crew Commander explained to us that the
purpose was to position the Langley fighters between the reported
southbound American 11 and the nation's capital.
At the suggestion of the Boston Center's military liaison, NEADS
contacted the FAA's Washington Center to ask about American 11. In
the course of the conversation, a Washington Center manager
informed NEADS that "We're looking ... we also lost American 77."
The time was 9:34 a.m. This was the first notice to the military
that American 77 was missing, and it had come by chance. If NEADS
had not placed that call, the NEADS air defenders would have
received no information whatsoever that American 77 was even
missing, although the FAA had been searching for it. No one at FAA
Command Center or headquarters ever asked for military assistance
with American 77.
At 9:36 a.m., the FAA's Boston Center called NEADS and relayed
the discovery about the aircraft closing in on Washington, an
aircraft that still had not been linked with the missing American
77. The FAA told NEADS: "Latest report. Aircraft VFR (Visual
Flight Rules) six miles southeast of the White House. Six,
southwest. Six, southwest of the White House, deviating away."
This startling news prompted the Mission Crew Commander at NEADS
to take immediate control of the airspace to clear a flight path
for the Langley fighters: "Okay, we're going to turn it, crank it
up. Run them to the White House." He then discovered, to his
surprise, that the Langley fighters were not headed north toward
the Baltimore area as instructed, but east over the ocean. "I
don't care how many windows you break," he said. "Damn it. Okay.
Push them back."
The Langley fighters were heading east, not north, for three
reasons. First, unlike a normal scramble order, this order did not
include a distance to the target, or the target's location. Second,
a "generic" flight plan incorrectly led the Langley fighters to
believe they were ordered to fly due east (090) for 60 miles. The
purpose of the generic flight plan was to quickly get the aircraft
airborne and out of local airspace. Third, the lead pilot and local
FAA controller incorrectly assumed the flight plan instruction to
go "090 for 60" was newer guidance that superseded the original
scramble order.
After the 9:36 a.m. call to NEADS about the unidentified
aircraft a few miles from the White House, the Langley fighters
were ordered to Washington, D.C. Controllers at NEADS located an
unknown primary radar track, but "it kind of faded" over
Washington. The time was 9:38 a.m. The Pentagon had been struck by
American 77 at 9:37:46 a.m. The Langley fighters were approximately
150 miles away.
Right after the Pentagon was hit, NEADS learned of another
possible hijacked aircraft. It was an aircraft that in fact had not
been hijacked at all. After the second World Trade Center crash,
Boston Center managers recognized both aircraft were
transcontinental, 767 jetliners that departed Logan Airport.
Remembering the "we have some planes" remark, Boston Center had
guessed that Delta 1989 might also be hijacked. Boston Center
called NEADS at 9:41 a.m. and identified Delta 1989, a 767 jet that
departed Logan Airport destined for Las Vegas, as a possible
hijack. NEADS warned the FAA's Cleveland air traffic control center
to watch Delta 1989. The FAA's Herndon Command Center and FAA
headquarters were watching it too. During the course of the
morning, there were multiple erroneous reports of hijacked aircraft
in the system. The report of American 11 heading south was the
first; Delta 1989 was the second.
NEADS never lost track of Delta 1989, and even launched fighter
aircraft from Ohio and Michigan to intercept it. The flight never
turned off its transponder. NEADS soon learned that the aircraft
was not hijacked, and tracked Delta 1989 as it reversed course over
Toledo, headed east, and landed in Cleveland. But another aircraft
was heading toward Washington.
The following is a time lapsed depiction of the flight path of
American 77. (Video image shown).
