When checked for his flight Boston, Atta was selected computerized prescreening system known CAPPS (Computer Assisted Passenger Prescreening System), created identify passengers who should
subject special security measures. Under security rules place the time,
the only consequence Atta selection CAPPS was that his checked bags
were held off the plane until was confirmed that had boarded the aircraft. This did not hinder Atta plans.2
Atta and Omari arrived Boston 6:45. Seven minutes later,Atta apparently took call from Marwan Shehhi, longtime colleague who was

THE 9/11 COMMISSION REPORT
Between 6:45 and 7:40,Atta and Omari, along with Satam Suqami,Wail Shehri, and Waleed Shehri, checked and boarded American Airlines
Flight 11, bound for Los Angeles.The flight was scheduled depart 7:45.4 another Logan terminal, Shehhi, joined Fayez Banihammad, Mohand Shehri, Ahmed Ghamdi, and Hamza Ghamdi, checked for United
Airlines Flight 175, also bound for Los Angeles.A couple Shehhi colleagues
were obviously unused travel; according the United ticket agent, they had
trouble understanding the standard security questions, and she had over
them slowly until they gave the routine, reassuring answers.5 Their flight was
scheduled depart 8:00.
The security checkpoints through which passengers, including Atta and his
colleagues, gained access the American gate were operated Globe

single checkpoint through which passengers for United 175 passed was controlled United Airlines, which had contracted with Huntleigh USA perform the screening.6 passing through these checkpoints, each the hijackers would have been

least the metal content .22-caliber handgun. Anyone who might have set
off that detector would have been screened with hand wand procedure
requiring the screener identify the metal item items that caused the alarm. addition, X-ray machine would have screened the hijackers carry-on
belongings.The screening was place identify and confiscate weapons and
other items prohibited from being carried onto commercial flight.7 None
the checkpoint supervisors recalled the hijackers reported anything suspicious regarding their screening.8
While Atta had been selected CAPPS Portland, three members his
hijacking team Suqami,Wail Shehri, and Waleed Shehri were selected Boston.Their selection affected only the handling their checked bags, not
their screening the checkpoint. All five men cleared the checkpoint and
made their way the gate for American 11. Atta, Omari, and Suqami took
their seats business class (seats 8D, 8G, and 10B, respectively). The Shehri
brothers had adjacent seats row (Wail 2A,Waleed 2B), the firstclass cabin. They boarded American between 7:31 and 7:40. The aircraft

because one the brothers did not have photo identification nor could
understand English, and because the agent found both the passengers suspicious.The only consequence their selection was that their checked
bags were held off the plane until was confirmed that they had boarded
the aircraft.12
All five hijackers passed through the Main Terminal west security screening checkpoint; United Airlines, which was the responsible air carrier, had
contracted out the work Argenbright Security.13 The checkpoint featured
closed-circuit television that recorded all passengers, including the hijackers, they were screened. 7:18, Mihdhar and Moqed entered the security
checkpoint.
Mihdhar and Moqed placed their carry-on bags the belt the X-ray
machine and proceeded through the first metal detector. Both set off the alarm,
and they were directed second metal detector. Mihdhar did not trigger the
alarm and was permitted through the checkpoint. After Moqed set off,
screener wanded him. passed this inspection.14
About minutes later, 7:35, another passenger for Flight 77, Hani Hanjour, placed two carry-on bags the X-ray belt the Main Terminal west
checkpoint, and proceeded, without alarm, through the metal detector. short
time later, Nawaf and Salem Hazmi entered the same checkpoint. Salem
Hazmi cleared the metal detector and was permitted through; Nawaf Hazmi
set off the alarms for both the first and second metal detectors and was then
hand-wanded before being passed. addition, his over-the-shoulder carry-on
bag was swiped explosive trace detector and then passed. The video
footage indicates that was carrying unidentified item his back pocket,
clipped its rim.15
When the local civil aviation security office the Federal Aviation Administration (FAA) later investigated these security screening operations, the
screeners recalled nothing out the ordinary.They could not recall that any the passengers they screened were CAPPS selectees.We asked screening
expert review the videotape the hand-wanding, and found the quality the screener work have been marginal best. The screener should
have resolved what set off the alarm; and the case both Moqed and
Hazmi, was clear that did not.16 7:50, Majed Moqed and Khalid Mihdhar boarded the flight and were

Nami, Ahmad Haznawi, and Ziad Jarrah checked the United Airlines
ticket counter for Flight 93, going Los Angeles.Two checked bags; two did
not. Haznawi was selected CAPPS. His checked bag was screened for explosives and then loaded the plane.18
The four men passed through the security checkpoint, owned United
Airlines and operated under contract Argenbright Security. Like the checkpoints Boston, lacked closed-circuit television surveillance there
documentary evidence indicate when the hijackers passed through the
checkpoint, what alarms may have been triggered, what security procedures
were administered.The FAA interviewed the screeners later; none recalled anything unusual suspicious.19
The four men boarded the plane between 7:39 and 7:48. All four had seats the first-class cabin; their plane had business-class section. Jarrah was
seat 1B, closest the cockpit; Nami was 3C, Ghamdi 3D, and Haznawi 6B.20
The men were aboard four transcontinental flights.21 They were planning hijack these planes and turn them into large guided missiles, loaded
with 11,400 gallons jet fuel. 8:00 A.M. the morning Tuesday,
September 11, 2001, they had defeated all the security layers that America civil
aviation security system then had place prevent hijacking.
The Hijacking American
American Airlines Flight provided nonstop service from Boston Los
Angeles. September 11, Captain John Ogonowski and First Officer
Thomas McGuinness piloted the Boeing 767. carried its full capacity nine
flight attendants. Eighty-one passengers boarded the flight with them (including the five terrorists).22
The plane took off 7:59. Just before 8:14, had climbed 26,000 feet,
not quite its initial assigned cruising altitude 29,000 feet.All communications
and flight profile data were normal. About this time the Fasten Seatbelt sign
would usually have been turned off and the flight attendants would have begun
preparing for cabin service.23 that same time, American had its last routine communication with
the ground when acknowledged navigational instructions from the FAA
air traffic control (ATC) center Boston. Sixteen seconds after that transmission,ATC instructed the aircraft pilots climb 35,000 feet.That message
and all subsequent attempts contact the flight were not acknowledged.
From this and other evidence, believe the hijacking began 8:14
shortly thereafter.24

9:12 HAVE SOME PLANES
Reports from two flight attendants the coach cabin, Betty Ong and
Madeline Amy Sweeney, tell most what know about how the
hijacking happened. began, some the hijackers most likely Wail
Shehri and Waleed Shehri, who were seated row first class stabbed
the two unarmed flight attendants who would have been preparing for cabin
service.25 not know exactly how the hijackers gained access the cockpit;
FAA rules required that the doors remain closed and locked during flight. Ong
speculated that they had jammed their way in. Perhaps the terrorists stabbed
the flight attendants get cockpit key, force one them open the cockpit door, lure the captain first officer out the cockpit. the flight
attendants may just have been their way.26 the same time shortly thereafter, Atta the only terrorist board
trained fly jet would have moved the cockpit from his business-class
seat, possibly accompanied Omari.As this was happening, passenger Daniel
Lewin, who was seated the row just behind Atta and Omari, was stabbed
one the hijackers probably Satam Suqami, who was seated directly
behind Lewin. Lewin had served four years officer the Israeli military. may have made attempt stop the hijackers front him, not realizing that another was sitting behind him.27
The hijackers quickly gained control and sprayed Mace, pepper spray,
some other irritant the first-class cabin, order force the passengers and
flight attendants toward the rear the plane.They claimed they had bomb.28
About five minutes after the hijacking began, Betty Ong contacted the
American Airlines Southeastern Reservations Office Cary, North Carolina,
via ATT airphone report emergency aboard the flight.This was the
first several occasions 9/11 when flight attendants took action outside
the scope their training, which emphasized that hijacking, they were
communicate with the cockpit crew.The emergency call lasted approximately minutes, Ong calmly and professionally relayed information about events
taking place aboard the airplane authorities the ground.29 8:19, Ong reported: The cockpit not answering, somebody stabbed business class and think there Mace that can breathe don
know, think getting hijacked. She then told the stabbings the two
flight attendants.30 8:21, one the American employees receiving Ong call North Carolina, Nydia Gonzalez, alerted the American Airlines operations center Fort
Worth,Texas, reaching Craig Marquis, the manager duty. Marquis soon realized this was emergency and instructed the airline dispatcher responsible
for the flight contact the cockpit. 8:23, the dispatcher tried unsuccessfully contact the aircraft. Six minutes later, the air traffic control specialist American operations center contacted the FAA Boston Air Traffic Control Center
about the flight. The center was already aware the problem.31

THE 9/11 COMMISSION REPORT
Boston Center knew problem the flight part because just before
8:25 the hijackers had attempted communicate with the passengers. The
microphone was keyed, and immediately one the hijackers said, Nobody
move. Everything will okay. you try make any moves, you endanger
yourself and the airplane. Just stay quiet. Air traffic controllers heard the transmission; Ong did not.The hijackers probably did not know how operate the
cockpit radio communication system correctly, and thus inadvertently broadcast their message over the air traffic control channel instead the cabin
public-address channel. Also 8:25, and again 8:29, Amy Sweeney got
through the American Flight Services Office Boston but was cut off after
she reported someone was hurt aboard the flight.Three minutes later, Sweeney
was reconnected the office and began relaying updates the manager,
Michael Woodward.32 8:26, Ong reported that the plane was flying erratically. minute later,
Flight turned south. American also began getting identifications the
hijackers, Ong and then Sweeney passed some the seat numbers
those who had gained unauthorized access the cockpit.33
Sweeney calmly reported her line that the plane had been hijacked;
man first class had his throat slashed; two flight attendants had been
stabbed one was seriously hurt and was oxygen while the other wounds
seemed minor; doctor had been requested; the flight attendants were unable contact the cockpit; and there was bomb the cockpit. Sweeney told
Woodward that she and Ong were trying relay much information they
could people the ground.34 8:38, Ong told Gonzalez that the plane was flying erratically again.
Around this time Sweeney told Woodward that the hijackers were Middle Easterners, naming three their seat numbers. One spoke very little English and
one spoke excellent English.The hijackers had gained entry the cockpit, and
she did not know how.The aircraft was rapid descent.35 8:41, Sweeney told Woodward that passengers coach were under the
impression that there was routine medical emergency first class. Other
flight attendants were busy duties such getting medical supplies while Ong
and Sweeney were reporting the events.36 8:41, American operations center, colleague told Marquis that the
air traffic controllers declared Flight hijacking and think [American
11] headed toward Kennedy [airport NewYork City].They moving everybody out the way.They seem have him primary radar.They seem
think that descending. 8:44, Gonzalez reported losing phone contact with Ong. About this
same time Sweeney reported Woodward, Something wrong.We are
rapid descent are all over the place. Woodward asked Sweeney look
out the window see she could determine where they were. Sweeney
responded: are flying low. are flying very, very low. are flying way

call ended.38 8:46:40,American crashed into the North Tower the World Trade
Center New York City.39 All board, along with unknown number
people the tower, were killed instantly.
The Hijacking United 175
United Airlines Flight 175 was scheduled depart for Los Angeles 8:00. Captain Victor Saracini and First Officer Michael Horrocks piloted the Boeing 767,
which had seven flight attendants. Fifty-six passengers boarded the flight.40
United 175 pushed back from its gate 7:58 and departed Logan Airport 8:14. 8:33, had reached its assigned cruising altitude 31,000 feet.The
flight attendants would have begun their cabin service.41
The flight had taken off just American was being hijacked, and 8:42
the United 175 flight crew completed their report suspicious transmission overheard from another plane (which turned out have been Flight 11)
just after takeoff. This was United 175 last communication with the ground.42
The hijackers attacked sometime between 8:42 and 8:46.They used knives
(as reported two passengers and flight attendant), Mace (reported one
passenger), and the threat bomb (reported the same passenger). They
stabbed members the flight crew (reported flight attendant and one passenger). Both pilots had been killed (reported one flight attendant).The eyewitness accounts came from calls made from the rear the plane, from
passengers originally seated further forward the cabin, sign that passengers
and perhaps crew had been moved the back the aircraft. Given similarities American hijacker seating and eyewitness reports tactics and
weapons, well the contact between the presumed team leaders, Atta and
Shehhi, believe the tactics were similar both flights.43
The first operational evidence that something was abnormal United

minute. 8:51, the flight deviated from its assigned altitude, and minute
later New York air traffic controllers began repeatedly and unsuccessfully trying contact it.44 8:52, Easton, Connecticut, man named Lee Hanson received

her flight was being hijacked six individuals who had moved them the

Ted Olson, the solicitor general the United States. She reported that the
flight had been hijacked, and the hijackers had knives and box cutters. She further indicated that the hijackers were not aware her phone call, and that they
had put all the passengers the back the plane. About minute into the
conversation, the call was cut off. Solicitor General Olson tried unsuccessfully reach Attorney General John Ashcroft.57
Shortly after the first call, Barbara Olson reached her husband again. She
reported that the pilot had announced that the flight had been hijacked, and
she asked her husband what she should tell the captain do.Ted Olson asked
for her location and she replied that the aircraft was then flying over houses.
Another passenger told her they were traveling northeast.The Solicitor General then informed his wife the two previous hijackings and crashes. She did
not display signs panic and did not indicate any awareness impending
crash.At that point, the second call was cut off.58 9:29, the autopilot American was disengaged; the aircraft was

The Battle for United 8:42, United Airlines Flight took off from Newark (New Jersey) Liberty
International Airport bound for San Francisco.The aircraft was piloted Captain Jason Dahl and First Officer Leroy Homer, and there were five flight attendants. Thirty-seven passengers, including the hijackers, boarded the plane.
Scheduled depart the gate 8:00, the Boeing 757 takeoff was delayed
because the airport typically heavy morning traffic.62
The hijackers had planned take flights scheduled depart 7:45 (American 11), 8:00 (United 175 and United 93), and 8:10 (American 77). Three
the flights had actually taken off within minutes their planned
departure times. United would ordinarily have taken off about minutes
after pulling away from the gate.When left the ground 8:42, the flight was
running more than minutes late.63 United left Newark, the flight crew members were unaware the
hijacking American 11.Around 9:00, the FAA,American, and United were
facing the staggering realization apparent multiple hijackings. 9:03, they
would see another aircraft strike the World Trade Center. Crisis managers
the FAA and the airlines did not yet act warn other aircraft.64 the same
time, Boston Center realized that message transmitted just before 8:25 the
hijacker pilot American included the phrase, have some planes. one the FAA the airlines that day had ever dealt with multiple
hijackings. Such plot had not been carried out anywhere the world more
than years, and never the United States.As news the hijackings filtered
through the FAA and the airlines, does not seem have occurred their
leadership that they needed alert other aircraft the air that they too might risk.66
United 175 was hijacked between 8:42 and 8:46, and awareness that
hijacking began spread after 8:51. American was hijacked between 8:51
and 8:54. 9:00, FAA and airline officials began comprehend that attackers were going after multiple aircraft. American Airlines nationwide ground
stop between 9:05 and 9:10 was followed United Airlines ground stop.
FAA controllers Boston Center, which had tracked the first two hijackings,
requested 9:07 that Herndon Command Center get messages airborne
aircraft increase security for the cockpit. There evidence that Herndon took such action. Boston Center immediately began speculating about
other aircraft that might danger, leading them worry about transcontinental flight Delta 1989 that fact was not hijacked. 9:19, the FAA
New England regional office called Herndon and asked that Cleveland Center advise Delta 1989 use extra cockpit security.67

Several FAA air traffic control officials told was the air carriers responsibility notify their planes security problems. One senior FAA air traffic
control manager said that was simply not the FAA place order the airlines what tell their pilots.68 believe such statements not reflect
adequate appreciation the FAA responsibility for the safety and security
civil aviation.
The airlines bore responsibility, too.They were facing escalating number conflicting and, for the most part, erroneous reports about other flights,
well continuing lack vital information from the FAA about the hijacked
flights.We found evidence, however, that American Airlines sent any cockpit warnings its aircraft 9/11. United first decisive action notify its
airborne aircraft take defensive action did not come until 9:19, when
United flight dispatcher, Ballinger, took the initiative begin transmitting
warnings his transcontinental flights: Beware any cockpit intrusion 
Two a/c [aircraft] hit World Trade Center. One the flights that received
the warning was United 93. Because Ballinger was still responsible for his
other flights well Flight 175, his warning message was not transmitted

United was received the cockpit.Within two minutes, 9:26, the pilot,
Jason Dahl, responded with note puzzlement: Ed, confirm latest mssg

The hijackers attacked 9:28. While traveling 35,000 feet above eastern
Ohio, United suddenly dropped 700 feet. Eleven seconds into the descent,
the FAA air traffic control center Cleveland received the first two radio
transmissions from the aircraft. During the first broadcast, the captain first

that the fight was continuing.The captain first officer could heard shouting: Hey get out here get out here get out here. the morning 9/11, there were only passengers United addition the hijackers.This was below the norm for Tuesday mornings
during the summer 2001. But there evidence that the hijackers manipulated passenger levels purchased additional seats facilitate their operation.72
The terrorists who hijacked three other commercial flights 9/11 operated five-man teams.They initiated their cockpit takeover within minutes takeoff. Flight 93, however, the takeover took place minutes after
takeoff and there were only four hijackers. The operative likely intended

THE 9/11 COMMISSION REPORT
Because several passengers United described three hijackers the
plane, not four, some have wondered whether one the hijackers had been
able use the cockpit jump seat from the outset the flight. FAA rules allow
use this seat documented and approved individuals, usually air carrier
FAA personnel.We have found evidence indicating that one the hijackers, anyone else, sat there this flight. All the hijackers had assigned seats first class, and they seem have used them.We believe more likely that
Jarrah, the crucial pilot-trained member their team, remained seated and
inconspicuous until after the cockpit was seized; and once inside, would not
have been visible the passengers.74 9:32, hijacker, probably Jarrah, made attempted make the following announcement the passengers Flight 93: Ladies and Gentlemen: Here
the captain, please sit down keep remaining sitting.We have bomb board.
So, sit. The flight data recorder (also recovered) indicates that Jarrah then
instructed the plane autopilot turn the aircraft around and head east.75
The cockpit voice recorder data indicate that woman, most likely flight
attendant, was being held captive the cockpit. She struggled with one the
hijackers who killed otherwise silenced her.76
Shortly thereafter, the passengers and flight crew began series calls from
GTE airphones and cellular phones. These calls between family, friends, and
colleagues took place until the end the flight and provided those the
ground with firsthand accounts. They enabled the passengers gain critical
information, including the news that two aircraft had slammed into the World
Trade Center.77 9:39, the FAA Cleveland Air Route Traffic Control Center overheard second announcement indicating that there was bomb board, that the
plane was returning the airport, and that they should remain seated.78 While apparently was not heard the passengers, this announcement, like those
Flight and Flight 77, was intended deceive them. Jarrah, like Atta earlier,
may have inadvertently broadcast the message because did not know how operate the radio and the intercom.To our knowledge none them had
ever flown actual airliner before. least two callers from the flight reported that the hijackers knew that passengers were making calls but did not seem care. quite possible Jarrah
knew the success the assault the World Trade Center. could have
learned this from messages being sent United Airlines the cockpits
its transcontinental flights, including Flight 93, warning cockpit intrusion
and telling the New York attacks. But even without them, would certainly have understood that the attacks the World Trade Center would
already have unfolded, given Flight tardy departure from Newark. Jarrah did know that the passengers were making calls, might not have occurred him that they were certain learn what had happened New York, thereby
defeating his attempts deception.79

9:12 HAVE SOME PLANES least ten passengers and two crew members shared vital information with
family, friends, colleagues, others the ground. All understood the plane
had been hijacked. They said the hijackers wielded knives and claimed have bomb.The hijackers were wearing red bandanas, and they forced the passengers the back the aircraft.80
Callers reported that passenger had been stabbed and that two people were
lying the floor the cabin, injured dead possibly the captain and first
officer. One caller reported that flight attendant had been killed.81
One the callers from United also reported that thought the hijackers might possess gun. But none the other callers reported the presence firearm. One recipient call from the aircraft recounted specifically asking her caller whether the hijackers had guns.The passenger replied that did
not see one. evidence firearms their identifiable remains was found the aircraft crash site, and the cockpit voice recorder gives indication gun being fired mentioned any time.We believe that the hijackers had
possessed gun, they would have used the flight last minutes the passengers fought back.82
Passengers three flights reported the hijackers claim having bomb.
The FBI told they found trace explosives the crash sites. One
the passengers who mentioned bomb expressed his belief that was not real.
Lacking any evidence that the hijackers attempted smuggle such illegal
items past the security screening checkpoints, believe the bombs were
probably fake.83
During least five the passengers phone calls, information was shared
about the attacks that had occurred earlier that morning the World Trade
Center. Five calls described the intent passengers and surviving crew members revolt against the hijackers. According one call, they voted
whether rush the terrorists attempt retake the plane. They decided,

FAA Control Centers often receive information and make operational decisions independently one another. 9/11, the four hijacked aircraft were
monitored mainly the centers Boston, New York, Cleveland, and Indianapolis. Each center thus had part the knowledge what was going
across the system.What Boston knew was not necessarily known centers
New York, Cleveland, Indianapolis, for that matter the Command
Center Herndon FAA headquarters Washington.
Controllers track airliners such the four aircraft hijacked 9/11 primarily watching the data from signal emitted each aircraft transponder
equipment.Those four planes, like all aircraft traveling above 10,000 feet, were
required emit unique transponder signal while flight.93 9/11, the terrorists turned off the transponders three the four
hijacked aircraft.With its transponder off, possible, though more difficult, track aircraft its primary radar returns. But unlike transponder data,
primary radar returns not show the aircraft identity and altitude. Controllers centers rely heavily transponder signals that they usually not
display primary radar returns their radar scopes. But they can change the
configuration their scopes they can see primary radar returns.They did this 9/11 when the transponder signals for three the aircraft disappeared.94
Before 9/11, was not unheard for commercial aircraft deviate

However, the simultaneous loss radio and transponder signal would rare

back course.Alarm bells would not start ringing until these efforts which
could take five minutes more were tried and had failed.95
NORAD Mission and Structure. NORAD binational command established 1958 between the United States and Canada. Its mission was, and is, defend the airspace North America and protect the continent.That mission does not distinguish between internal and external threats; but because
NORAD was created counter the Soviet threat, came define its job
defending against external attacks.96
The threat Soviet bombers diminished significantly the Cold War
ended, and the number NORAD alert sites was reduced from its Cold War
high 26. Some within the Pentagon argued the 1990s that the alert sites

NORAD perceived the dominant threat from cruise missiles. Other
threats were identified during the late 1990s, including terrorists use aircraft weapons. Exercises were conducted counter this threat, but they were not

Notwithstanding the identification these emerging threats, 9/11 there

The NMCC would keep the FAA hijack coordinator date and help
the FAA centers coordinate directly with the military. NORAD would receive
tracking information for the hijacked aircraft either from joint use radar from
the relevant FAA air traffic control facility. Every attempt would made
have the hijacked aircraft squawk 7500 help NORAD track it.104
The protocols did not contemplate intercept.They assumed the fighter
escort would discreet, vectored position five miles directly behind the
hijacked aircraft, where could perform its mission monitor the aircraft

 the hijacked aircraft would readily identifiable and would not
attempt disappear;
 there would time address the problem through the appropriate
FAA and NORAD chains command; and
 the hijacking would take the traditional form: that is, would not suicide hijacking designed convert the aircraft into guided

general the First Air Force and NORAD Continental Region. Marr sought
authorization scramble the Otis fighters. General Arnold later recalled
instructing Marr ahead and scramble them, and get authorities
later. General Arnold then called NORAD headquarters report.118
F-15 fighters were scrambled 8:46 from Otis Air Force Base. But NEADS
did not know where send the alert fighter aircraft, and the officer directing
the fighters pressed for more information: don know where scrambling

searching their radar scopes for the primary radar return. American struck
the North Tower 8:46. Shortly after 8:50, while NEADS personnel were still
trying locate the flight, word reached them that plane had hit the World
Trade Center.119

after entering New York Center airspace, the pilot United 175 broke
with the following transmission:
UAL 175: New York UAL 175 heavy.
FAA: UAL 175 ahead.
UAL 175:Yeah.We figured wait your center.Ah, heard suspicious transmission our departure out Boston, ah, with
someone, ah, sounded like someone keyed the mikes and said
everyone stay your seats.
FAA: Oh, okay. pass that along over here.122
Minutes later, United 175 turned southwest without clearance from air traffic control. 8:47, seconds after the impact American 11, United 175
transponder code changed, and then changed again. These changes were not
noticed for several minutes, however, because the same New York Center controller was assigned both American and United 175.The controller knew
American was hijacked; was focused searching for after the aircraft
disappeared 8:46.123 8:48, while the controller was still trying locate American 11, New
York Center manager provided the following report Command Center

have control the aircraft, and that all the information they have
right now.124
The New York Center controller and manager were unaware that American had already crashed. 8:51, the controller noticed the transponder change from United 175 and
tried contact the aircraft.There was response. Beginning 8:52, the controller made repeated attempts reach the crew United 175. Still

find the aircraft.125
Another commercial aircraft the vicinity then radioed with reports
over the radio commuter plane hitting the World Trade Center. The controller spent the next several minutes handing off the other flights his scope other controllers and moving aircraft out the way the unidentified aircraft (believed United 175) moved southwest and then turned
northeast toward New York City.126 about 8:55, the controller charge notified New York Center manager that she believed United 175 had also been hijacked.The manager tried notify the regional managers and was told that they were discussing
hijacked aircraft (presumably American 11) and refused disturbed.At 8:58,
the New York Center controller searching for United 175 told another New
York controller might have hijack over here, two them. 127
Between 9:01 and 9:02, manager from New York Center told the Command Center Herndon:
Manager, New York Center: have several situations going here.
escalating big, big time.We need get the military involved with us. re, involved with something else, have other aircraft that
may have similar situation going here.128
The other aircraft referred New York Center was United 175. Evidence indicates that this conversation was the only notice received either
FAA headquarters the Herndon Command Center prior the second crash
that there had been second hijacking.
While the Command Center was told about this other aircraft 9:01,
New York Center contacted New York terminal approach control and asked
for help locating United 175.
Terminal: got somebody who keeps coasting but looks like going
into one the small airports down there.
Center: Hold second. trying bring him here and get
you There right there. Hold on.
Terminal: Got him just out 9,500 9,000 now.
Center: you know who is?
Terminal: just, just don know who is.We just picking him now.
Center (at 9:02): Alright. Heads man, looks like another one coming in.129
The controllers observed the plane rapid descent; the radar data terminated over Lower Manhattan. 9:03, United 175 crashed into the South

Meanwhile, manager from Boston Center reported that they had deciphered what they had heard one the first hijacker transmissions from
American 11:
Boston Center: Hey you still there?
New England Region: Yes, am.
Boston Center: far the tape, Bobby seemed think the guy
said that have planes. Now, don know was because was
the accent, there more than one, but gonna, gonna
reconfirm that for you, and get back you real quick. Okay?
New England Region: Appreciate it.
Unidentified Female Voice: They have what?
Boston Center: Planes, plural.
Boston Center: sounds like, talking New York, that there
another one aimed the World Trade Center.
New England Region: There another aircraft?
Boston Center: second one just hit the Trade Center.
New England Region: Okay.Yeah, gotta get gotta alert the
military real quick this.131
Boston Center immediately advised the New England Region that was
going stop all departures airports under its control. 9:05, Boston Center confirmed for both the FAA Command Center and the New England
Region that the hijackers aboard American said have planes. the
same time, New York Center declared ATC zero meaning that aircraft were
not permitted depart from, arrive at, travel through New York Center
airspace until further notice.132
Within minutes the second impact, Boston Center instructed its controllers inform all aircraft its airspace the events New York and
advise aircraft heighten cockpit security. Boston Center asked the Herndon
Command Center issue similar cockpit security alert nationwide.We have
found evidence suggest that the Command Center acted this request issued any type cockpit security alert.133
Military Notification and Response. The first indication that the
NORAD air defenders had the second hijacked aircraft, United 175, came phone call from New York Center NEADS 9:03.The notice came
about the time the plane was hitting the South Tower.134 9:08, the mission crew commander NEADS learned the second
explosion the World Trade Center and decided against holding the fighters military airspace away from Manhattan:
Mission Crew Commander, NEADS: This what foresee that
probably need do.We need talk FAA.We need tell

this stuff gonna keep going, need take those fighters, put over Manhattan.That best thing, that the best play right now. coordinate with the FAA.Tell there more out there, which don know, let get over Manhattan.At least got some kind play.135
The FAA cleared the airspace. Radar data show that 9:13, when the Otis
fighters were about 115 miles away from the city, the fighters exited their holding pattern and set course direct for Manhattan. They arrived 9:25 and
established combat air patrol (CAP) over the city.136
Because the Otis fighters had expended great deal fuel flying first
military airspace and then New York, the battle commanders were concerned about refueling. NEADS considered scrambling alert fighters from Langley Air Force Base Virginia New York, provide backup.The Langley
fighters were placed battle stations 9:09.137 NORAD had indication
that any other plane had been hijacked.
American Airlines Flight
FAA Awareness. American began deviating from its flight plan 8:54,
with slight turn toward the south.Two minutes later, disappeared completely
from radar Indianapolis Center, which was controlling the flight.138
The controller tracking American told noticed the aircraft turning the southwest, and then saw the data disappear.The controller looked
for primary radar returns. searched along the plane projected flight path
and the airspace the southwest where had started turn. primary targets appeared. tried the radios, first calling the aircraft directly, then the airline.Again there was nothing.At this point, the Indianapolis controller had
knowledge the situation New York. did not know that other aircraft
had been hijacked. believed American had experienced serious electrical mechanical failure, both, and was gone.139
Shortly after 9:00, Indianapolis Center started notifying other agencies that
American was missing and had possibly crashed.At 9:08, Indianapolis Center asked Air Force Search and Rescue Langley Air Force Base look for
downed aircraft.The center also contacted the West Virginia State Police and
asked whether any reports downed aircraft had been received. 9:09,
reported the loss contact the FAA regional center, which passed this information FAA headquarters 9:24.140 9:20, Indianapolis Center learned that there were other hijacked aircraft,
and began doubt its initial assumption that American had crashed.A discussion this concern between the manager Indianapolis and the Command Center Herndon prompted notify some FAA field facilities that

The failure find primary radar return for American led 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 8:56. But for minutes and seconds, between 8:56 and 9:05,
this primary radar information American was not displayed controllers Indianapolis Center.142 The reasons are technical, arising from the way the
software processed radar information, well from poor primary radar coverage where American was flying.
According the radar reconstruction,American reemerged primary
target Indianapolis Center radar scopes 9:05, east its last known position.The target remained Indianapolis Center airspace for another six minutes, then crossed into the western portion Washington Center airspace
9:10.As Indianapolis Center continued searching for the aircraft, two managers
and the controller responsible for American looked the west and southwest along the flight projected path, not east where the aircraft was now
heading. Managers did not instruct other controllers Indianapolis Center
turn their primary radar coverage join the search for American 77.143 sum, Indianapolis Center never saw Flight turn around. the time reappeared primary radar coverage, controllers had either stopped looking for the aircraft because they thought had crashed were looking toward
the west. Although the Command Center learned Flight was missing, neither nor FAA headquarters issued all points bulletin surrounding centers search for primary radar targets. American traveled undetected for minutes course heading due east for Washington, D.C.144 9:25, FAA Herndon Command Center and FAA headquarters knew
two aircraft had crashed into the World Trade Center.They knew American
was lost. least some FAA officials Boston Center and the New England
Region knew that hijacker board American had said have some
planes. Concerns over the safety other aircraft began mount.A manager

headquarters, the Command Center ordered one 9:25.145
The Command Center kept looking for American 77. 9:21, advised the
Dulles terminal control facility, and Dulles urged its controllers look for primary targets. 9:32, they found one. Several the Dulles controllers
 observed primary radar target tracking eastbound high rate speed and
notified Reagan National Airport. FAA personnel both Reagan National and
Dulles airports notified the Secret Service. The aircraft identity type was
unknown.146

impact, reported the control tower: looks like that aircraft crashed into the
Pentagon sir. 147
Military Notification and Response. NORAD heard nothing about the
search for American 77. Instead, the NEADS air defenders heard renewed
reports about plane that longer existed: American 11. 9:21, NEADS received report from the FAA:
FAA: Military, Boston Center. just had report that American still the air, and its way towards heading towards Washington.
NEADS: Okay. American still the air?
FAA: Yes.
NEADS: its way towards Washington?
FAA: That was another was evidently another aircraft that hit the
tower.That the latest report have.
NEADS: Okay.
FAA: going try confirm for you, but would assume somewhere over, uh, either New Jersey somewhere further
south.
NEADS: Okay. American isn the hijack all then, right?
FAA: No, hijack.
NEADS: American hijack?
FAA: Yes.
NEADS: And heading into Washington?
FAA: Yes.This could third aircraft.148
The mention third aircraft was not reference American 77.There
was confusion that moment the FAA.Two planes had struck the World
Trade Center, and Boston Center had heard from FAA headquarters Washington that American was still airborne.We have been unable identify the
source this mistaken FAA information.
The NEADS technician who took this call from the FAA immediately
passed the word the mission crew commander, who reported the
NEADS battle commander:
Mission Crew Commander, NEADS: Okay, uh, American Airlines

9:12 HAVE SOME PLANES
After consulting with NEADS command, the crew commander issued the
order 9:23: Okay scramble Langley. Head them towards the Washington
area. [I]f they there then run them. .These guys are smart. 
That order was processed and transmitted Langley Air Force Base 9:24.
Radar data show the Langley fighters airborne 9:30. NEADS decided
keep the Otis fighters over New York.The heading the Langley fighters was
adjusted send them the Baltimore area. The mission crew commander
explained that the purpose was position the Langley fighters between
the reported southbound American and the nation capital.150 the suggestion the Boston Center military liaison, NEADS contacted
the FAA Washington Center ask about American 11. the course the
conversation, Washington Center manager informed NEADS: looking also lost American 77. The time was 9:34.151 This was the first notice the military that American was missing, and had come chance.
NEADS had not placed that call, the NEADS air defenders would have
received information whatsoever that the flight was even missing, although
the FAA had been searching for it. one FAA headquarters ever asked for
military assistance with American 77. 9:36, the FAA Boston Center called NEADS and relayed the discovery
about unidentified aircraft closing Washington: Latest report.Aircraft
VFR [visual flight rules] six miles southeast the White House. Six, southwest. Six, southwest the White House, deviating away. This startling news
prompted the mission crew commander NEADS take immediate control the airspace clear flight path for the Langley fighters: Okay, going turn crank up. Run them the White House. then discovered, his surprise, that the Langley fighters were not headed north toward
the Baltimore area instructed, but east over the ocean. don care how many
windows you break, said. Damn it. Okay. Push them back. 152
The Langley fighters were heading east, not north, for three reasons. First,
unlike normal scramble order, this order did not include distance the target the target location. Second, generic flight plan prepared get the
aircraft airborne and out local airspace quickly incorrectly led the Langley fighters believe they were ordered fly due east (090) for miles.Third,
the lead pilot and local FAA controller incorrectly assumed the flight plan
instruction 090 for superseded the original scramble order.153
After the 9:36 call NEADS about the unidentified aircraft few miles
from the White House, the Langley fighters were ordered Washington, D.C.
Controllers NEADS located unknown primary radar track, but kind faded over Washington.The time was 9:38.The Pentagon had been struck American 9:37:46.The Langley fighters were about 150 miles away.154

both aircraft were transcontinental 767 jetliners that had departed Logan Airport. Remembering the have some planes remark, Boston Center
guessed that Delta 1989 might also hijacked. Boston Center called NEADS 9:41 and identified Delta 1989, 767 jet that had left Logan Airport for Las
Vegas, possible hijack. NEADS warned the FAA Cleveland Center
watch Delta 1989.The Command Center and FAA headquarters watched
too. During the course the morning, there were multiple erroneous reports hijacked aircraft. The report American heading south was the first;
Delta 1989 was the second.155
NEADS never lost track Delta 1989, and even ordered fighter aircraft
from Ohio and Michigan intercept it. The flight never turned off its
transponder. NEADS soon learned that the aircraft was not hijacked, and
tracked Delta 1989 reversed course over Toledo, headed east, and landed Cleveland.156 But another aircraft was heading toward Washington, aircraft about which NORAD had heard nothing: United 93.
United Airlines Flight
FAA Awareness. 9:27, after having been the air for minutes, United acknowledged transmission from the Cleveland Center controller.This was
the last normal contact the FAA had with the flight.157
Less than minute later, the Cleveland controller and the pilots aircraft the vicinity heard radio transmission unintelligible sounds possible
screaming struggle from unknown origin. 158
The controller responded, seconds later: Somebody call Cleveland? This
was followed second radio transmission, with sounds screaming. The
Cleveland Center controllers began try identify the possible source the
transmissions, and noticed that United had descended some 700 feet.The
controller attempted again raise United several times, with response. 9:30, the controller began poll the other flights his frequency determine they had heard the screaming; several said they had.159 9:32, third radio transmission came over the frequency: Keep remaining sitting.We have bomb board. The controller understood, but chose respond: Calling Cleveland Center, you unreadable. Say again, slowly. notified his supervisor, who passed the notice the chain command. 9:34, word the hijacking had reached FAA headquarters.160
FAA headquarters had this time established open line communication with the Command Center Herndon and instructed poll all its
centers about suspect aircraft.The Command Center executed the request and, minute later, Cleveland Center reported that United may have bomb board. 9:34, the Command Center relayed the information concerning
United FAA headquarters.At approximately 9:36, Cleveland advised the
Command Center that was still tracking United and specifically inquired
whether someone had requested the military launch fighter aircraft intercept the aircraft. Cleveland even told the Command Center was prepared

Cleveland that FAA personnel well above them the chain command had make the decision seek military assistance and were working the issue.161
Between 9:34 and 9:38, the Cleveland controller observed United climbing 40,700 feet and immediately moved several aircraft out its way.The controller continued try contact United 93, and asked whether the pilot could
confirm that had been hijacked.162 There was response.
Then, 9:39, fourth radio transmission was heard from United 93:
Ziad Jarrah: Uh, this the captain.Would like you all remain seated.
There bomb board and are going back the airport, and
have our demands [unintelligible]. Please remain quiet.
The controller responded: United 93, understand you have bomb
board. ahead. The flight did not respond.163
From 9:34 10:08, Command Center facility manager provided frequent
updates Acting Deputy Administrator Monte Belger and other executives
FAA headquarters United headed toward Washington, D.C. 9:41,
Cleveland Center lost United transponder signal. The controller located primary radar, matched its position with visual sightings from other aircraft, and tracked the flight turned east, then south.164 9:42, the Command Center learned from news reports that plane had
struck the Pentagon.The Command Center national operations manager, Ben
Sliney, ordered all FAA facilities instruct all aircraft land the nearest
airport.This was unprecedented order.The air traffic control system handled with great skill, about 4,500 commercial and general aviation aircraft
soon landed without incident.165 9:46 the Command Center updated FAA headquarters that United
was now twenty-nine minutes out Washington, D.C. 9:49, minutes after Cleveland Center had asked about getting military help, the Command Center suggested that someone headquarters should
decide whether request military assistance:

aircraft. Then the Command Center informed headquarters that controllers
had lost track United over the Pittsburgh area.Within seconds, the Command Center received visual report from another aircraft, and informed headquarters that the aircraft was miles northwest Johnstown. United was
spotted another aircraft, and, 10:01, the Command Center advised FAA
headquarters that one the aircraft had seen United waving his wings. 
The aircraft had witnessed the hijackers efforts defeat the passengers counterattack.167
United crashed Pennsylvania 10:03:11, 125 miles from Washington,
D.C. The precise crash time has been the subject some dispute.The 10:03:11
impact time supported previous National Transportation Safety Board
analysis and evidence from the Commission staff analysis radar, the flight
data recorder, the cockpit voice recorder, infrared satellite data, and air traffic
control transmissions.168
Five minutes later, the Command Center forwarded this update headquarters:
Command Center: O.K. Uh, there now that United 93.
FAA Headquarters: Yes.
Command Center: There report black smoke the last position gave you, fifteen miles south Johnstown.
FAA Headquarters: From the airplane from the ground?
Command Center: Uh, they speculating from the aircraft.
FAA Headquarters: Okay.
Command Center: Uh, who, hit the ground.That what they speculating, that speculation only.169
The aircraft that spotted the black smoke was the same unarmed Air
National Guard cargo plane that had seen American crash into the Pentagon minutes earlier. had resumed its flight Minnesota and saw the
smoke from the crash United 93, less than two minutes after the plane went
down. 10:17, the Command Center advised headquarters its conclusion
that United had indeed crashed.170
Despite the discussions about military assistance, one from FAA headquarters requested military assistance regarding United 93. Nor did any manager FAA headquarters pass any the information had about United the military.
Military Notification and Response. NEADS first received call about
United from the military liaison Cleveland Center 10:07. Unaware that
the aircraft had already crashed, Cleveland passed NEADS the aircraft last
known latitude and longitude. NEADS was never able locate United

Clarifying the Record
The defense U.S. airspace 9/11 was not conducted accord with preexisting training and protocols. was improvised civilians who had never
handled hijacked aircraft that attempted disappear, and military unprepared for the transformation commercial aircraft into weapons mass
destruction. turned out, the NEADS air defenders had nine minutes 
notice the first hijacked plane, advance notice the second, advance
notice the third, and advance notice the fourth. not believe that the true picture that morning reflects discredit
the operational personnel NEADS FAA facilities. NEADS commanders
and officers actively sought out information, and made the best judgments they
could the basis what they knew. Individual FAA controllers, facility managers,and Command Center managers thought outside the box recommending nationwide alert, ground-stopping local traffic, and, ultimately,
deciding land all aircraft and executing that unprecedented order flawlessly.

More than the actual events, inaccurate government accounts those events
made appear that the military was notified time respond two the
hijackings, raising questions about the adequacy the response.Those accounts
had the effect deflecting questions about the military capacity obtain
timely and accurate information from its own sources. addition, they overstated the FAA ability provide the military with timely and useful information that morning. public testimony before this Commission May 2003, NORAD officials stated that 9:16, NEADS received hijack notification United from
the FAA.175 This statement was incorrect.There was hijack report 9:16.
United was proceeding normally that time. this same public testimony, NORAD officials stated that 9:24,
NEADS received notification the hijacking American 77.176 This statement was also incorrect.The notice NEADS received 9:24 was that American had not hit the World Trade Center and was heading for Washington,
D.C.177 their testimony and other public accounts, NORAD officials also
stated that the Langley fighters were scrambled respond the notifications
about American 77,178 United 93, both.These statements were incorrect
well.The fighters were scrambled because the report that American was
heading south, clear not just from taped conversations NEADS but also
from taped conversations FAA centers; contemporaneous logs compiled
NEADS, Continental Region headquarters, and NORAD; and other records.
Yet this response phantom aircraft was not recounted single public
timeline statement issued the FAA Department Defense.The inaccurate accounts created the impression that the Langley scramble was logical
response actual hijacked aircraft. fact, not only was the scramble prompted the mistaken information
about American 11, but NEADS never received notice that American was
hijacked. was notified 9:34 that American was lost.Then, minutes later,
NEADS was told that unknown plane was miles southwest the White
House. Only then did the already scrambled airplanes start moving directly
toward Washington, D.C.
Thus the military did not have minutes respond American 77,
testimony the Commission May 2003 suggested. had most one
two minutes react the unidentified plane approaching Washington, and
the fighters were the wrong place able help.They had been responding report about aircraft that did not exist.

1.3 NATIONAL CRISIS MANAGEMENT
When American struck the World Trade Center 8:46, one the White
House traveling with the President knew that had been hijacked.While
that information circulated within the FAA, found evidence that the
hijacking was reported any other agency Washington before 8:46.179
Most federal agencies learned about the crash New York from CNN.180
Within the FAA, the administrator, Jane Garvey, and her acting deputy, Monte
Belger, had not been told confirmed hijacking before they learned from
television that plane had crashed.181 Others the agency were aware it, explained earlier this chapter.
