American Airlines Flight 11

American Airlines Flight 11 was a domestic passenger flight that was hijacked by five al-Qaeda terrorists on the morning of September 11, 2001, as part of the September 11 attacks. The hijacked airliner was deliberately crashed into the North Tower of the World Trade Center complex in New York City, killing everyone aboard the flight and resulting in the deaths of more than one thousandTemplate:Efn people in the top 18 stories of the skyscraper in addition to causing the demise of numerous others below the trapped floors. The crash of Flight 11 stands as the deadliest of the four suicide attacks executed that morning in terms of both plane and ground fatalities, the single deadliest act of terrorism in human historyTemplate:Efn and the deadliest plane crash of all time.Template:Efn The aircraft involved, a Boeing 767-200ER with 92 passengers and crew, was flying American Airlines' daily scheduled morning transcontinental service from Boston Logan International Airport in Massachusetts to Los Angeles International Airport in California.

The airplane left the runway at 07:59. Less than fifteen minutes after takeoff, the hijackers injured two flight attendants, murdered one passenger, and breached the cockpit while forcing the passengers and crew to the rear of the aircraft. The assailants attacked both pilots, allowing lead hijacker Mohamed Atta to take over the controls. Air traffic controllers suspected that the flight was in distress because the crew became non-responsive. The air traffic controllers realized that the plane had been hijacked when Atta's announcement to the hostages was accidentally transmitted to air traffic control instead of through the aircraft's PA system. Also, two flight attendants were able to contact American Airlines and pass along information relevant to the situation, including casualties suffered by the crew and passengers.

Atta flew the hijacked plane into the North Tower at the World Trade Center from floors 93 through 99 at 08:46 local time. The impact was witnessed by countless people in the streets of New York City as well as the nearby state of New Jersey. The media quickly began reporting on the incident and speculated that the crash had been an accident. Seventeen minutes later, United Airlines Flight 175 crashed into the World Trade Center's South Tower at 09:03, instantly dispelling any notion it was accidental.

The damage caused by the plane and the fires ignited by its crash caused the North Tower to collapse at 10:28 that morning, resulting in hundreds of additional casualties. While the recovery effort at the World Trade Center site did lead to the discovery and identification of body fragments from certain individuals who boarded Flight11, many have not been identified.

Flight

The aircraft involved in the hijacking was a Boeing 767-200ER with registration number N334AA, built and delivered in 1987. The capacity of the aircraft was 158passengers (9 in first class, 30 in business class and 119 in economy class), but the September11 flight carried 81passengers and 11crew members. This was a light load at 58percent capacity, but higher than the average load factor for Flight11 on Tuesday mornings of 39percent in the months preceding September11. The crew members were Captain John Ogonowski (50), First Officer Thomas McGuinness Jr. (42) (a former Navy fighter pilot), purser Karen Martin and flight attendants Barbara Arestegui, Jeffrey Collman, Sara Low, Kathleen Nicosia, Betty Ong, Jean Roger, Dianne Snyder, and Amy Sweeney.

All 92 people on board were killed, including Frasier creator and executive producer David Angell, his wife Lynn Angell, actress Berry Berenson (widow of fellow actor Anthony Perkins), and Akamai Technologies co-founder Daniel Lewin. Family Guy creator Seth MacFarlane had been scheduled to be on the flight but overslept due to a hangover and arrived at the airport too late. Actor Mark Wahlberg was also scheduled to be on the flight but changed his plans and canceled his ticket the day before. Actress Leighanne Littrell, wife of Backstreet Boys singer Brian Littrell, had also previously been booked on the flight but, like Wahlberg, changed her plans.

Boarding

Portland, Maine

Mohamed Atta, the ringleader of the attacks, and fellow hijacker Abdulaziz al-Omari arrived at Portland International Jetport in Maine at 05:41 Eastern Daylight Time on September11, 2001. At the Portland ticket counter, Atta asked ticket agent Mike Tuohey for his boarding pass for Flight 11. When Tuohey told Atta he would have to check in a second time when he reached Logan, Atta appeared on the verge of anger, telling Tuohey that he had been assured he would have "one-step check-in." Becoming concerned he was racially profiling Atta, Tuohey, although uneasy with Atta's anger, simply told him that he would better hurry if he did not want to miss the flight. Although Atta still looked cross, he and Omari left the ticket counter for the Portland airport's security checkpoint.

They boarded Colgan Air Flight5930, which was scheduled to depart at 06:00 and fly to Boston. Both hijackers had first class tickets with a connecting flight to Los Angeles; Atta checked in two bags, a green Travel Gear bag and a black Travelpro bag, while Omari checked in none. When they checked in, the Computer-Assisted Passenger Prescreening System (CAPPS) selected Atta for extra luggage scrutiny, but he boarded without incident.

The flight from Portland departed on time and arrived in Boston at 06:45. Three other hijackers, Waleed al-Shehri, Wail al-Shehri, and Satam al-Suqami, arrived at Logan Airport at the same time, having left their rental car in the airport parking facility. At 06:52, Marwan al-Shehhi, the hijacker pilot of United Airlines Flight 175, made a call from a pay phone in Logan Airport to Atta's cell phone. This call was apparently to confirm that the attacks were ready to begin.

Boston, Massachusetts

Since they were not given boarding passes for Flight11 in Portland, Atta and Omari checked in and went through security in Boston. Suqami, Wail al-Shehri, and Waleed al-Shehri also checked in for the flight in Boston. Wail al-Shehri and Suqami each checked one bag; Waleed al-Shehri did not check any bags. CAPPS selected all three for a detailed luggage check. As the CAPPS' screening was only for luggage, the three hijackers did not undergo any extra scrutiny at the passenger security checkpoint.

First Officer Lynn Howland had just arrived in Boston after copiloting the flight from San Francisco that would be redesignated American Flight 11. As she walked off the aircraft and entered the passenger lounge, Atta approached her and asked if she would be flying the plane back across the country. When Howland told him she just brought the aircraft in, Atta turned his back and walked away. As he boarded Flight 11, Atta asked a gate agent whether the two bags he had checked earlier in Portland had been loaded onto the plane. In the rushed check-in after the flight from Portland, airline officials did not load Atta's bags on Flight11.

By 07:40, all five hijackers were aboard the flight, scheduled to depart at 07:45. Atta sat in business class seat 8D with al-Omari in 8G and Suqami in 10B. Waleed and Wail al-Shehri sat in first class seats 2B and 2A. Shortly before takeoff, American Airlines flight service manager Michael Woodward walked aboard for a final check. He briefly passed Atta, later reporting him as having a brooding expression, and then left the plane. At 07:46, one minute behind schedule, the aircraft received clearance to push back from Gate B32, and was cleared to taxi to the runway at 07:50. The aircraft began its takeoff roll from Logan International Airport at 07:59 from runway4R.

Hijacking

"Okay, my name is Betty Ong. I'm [Flight Attendant] Number3 on Flight11. Our Number1 got stabbed. Our purser is stabbed. Nobody knows who stabbed who and we can't even get up to business class right now because nobody can breathe. And we can't get to the cockpit, the door won't open."

- Flight attendant Betty Ong to the American Airlines emergency line.

The 9/11 Commission estimated that the hijacking began at 08:14Template:Efn when the pilots stopped responding to requests from the Boston Air Route Traffic Control Center (Boston ARTCC). At 08:13:29, as the aircraft was passing over central Massachusetts at , the pilots responded to a request from Boston ARTCC to make a 20-degree turn to the right. At 08:13:47, Boston ARTCC told the pilots to ascend to a cruising altitude of , but received no response. At 08:16, the aircraft leveled off at and shortly thereafter deviated from its scheduled path.

At 08:17:59, flight controllers at Boston Center heard a brief, unknown sound on the radio frequency used by Flight 11 and other nearby flights, a noise that was later described as sounding like a scream. Boston ARTCC made multiple attempts to talk to Flight11 without reply. The commission believes that the hijackers were in absolute control of the aircraft by 08:20,Template:R/superscript six minutes after launching their assault. The flight's Mode-C transponder signal was then switched off by someone in the cockpit at 08:21. At 08:23 and 08:25, Aircraft Communication Addressing and Reporting System (ACARS) tried to contact the flight. The first message read, "Good morning, ATC looking for you on 135.32"; the other read, "Please contact Boston Center ASAP. They have lost radio contact and your transponder signal." Flight 11 did not reply.

Reports from flight attendants

According to flight attendants Amy Sweeney and Betty Ong, who contacted American Airlines during the hijacking, the hijackers had stabbed flight attendants Karen Martin and Barbara Arestegui and slashed passenger Daniel Lewin's throat. It is unknown how the hijackers gained access to the cockpit; FAA rules at the time required that the doors remain closed and locked during flight. Ong said she thought that the hijackers had "jammed their way" in. Ong's and Sweeney's calls indicate that all five hijackers barricaded themselves in the cockpit.

The commission suggested the hijackers attacked the flight attendants to get a cockpit key, to force one of them to open the cockpit door, or to lure the captain or first officer out of the cockpit. It is theorized that Atta initiated the hijacking by giving a signal and that the al-Shehri brothers made the first move by attacking Martin and Arestegui; Sweeney said that Martin was badly injured and being given oxygen. Sweeney and Ong said Arestegui's injuries were not as serious. Ong said she heard loud arguing after the hijackers entered the cockpit. It is believed that the hijackers either killed or incapacitated Ogonowski and McGuinness.Template:Efn Sweeney said that one of the hijackers had shown her a device with red and yellow wires that appeared to be a bomb. Ong and Sweeney said that the coach passengers did not seem to fully understand the peril, and were under the impression from the flight attendants that there was a routine medical emergency in the front section of the plane (it is possible that the passengers evacuated from first and business, who witnessed the attack, went along with this in order to prevent the spread of panic) and that the other flight attendants were helping passengers and finding medical supplies. Ong said Lewin appeared to be dead, while Sweeney said that Suqami had attacked Lewin. Lewin was seated in 9B, and Suqami sat directly behind him in 10B.

One version of events is that Suqami attacked Lewin, unprovoked, to frighten other passengers and crew into compliance.Template:Efn Alternatively, Lewin, an American-Israeli Internet entrepreneur who understood Arabic, and had served as an officer in the elite Sayeret Matkal special operations unit of the Israel Defense Forces, may have attempted to intervene in the hijacking, and confronted the hijackers in front of him, unaware of Suqami behind him. Lewin is believed to be the first fatality in the 9/11 attacks. During a four-minute call to the American Airlines operations center, Ong provided information about lack of communication with the cockpit, lack of access to the cockpit, and that she thought someone had sprayed Mace in the business class cabin. She also provided the seat locations of the hijackers, which later helped investigators to determine their identities.

Hijacker's transmissions

At 08:24:38, Atta's voice was heard by Boston Air traffic controllers, saying, "We have some planes. Just stay quiet and you'll be O.K. We are returning to the airport." At 08:24:56, he announced, "Nobody move. Everything will be okay. If you try to make any moves, you'll endanger yourself and the airplane. Just stay quiet."

Atta apparently tried to make an announcement to the passengers, but keyed the wrong switch and instead his voice was picked up and recorded by air traffic controllers. There are no reports of anyone on the plane hearing the hijacker's transmission.Template:Efn After Atta's transmissions and the inability to contact the airliner, air traffic controllers at Boston ARTCC began to realize that Flight 11 was being hijacked. At 08:26, after crossing the Massachusetts-New York border, the plane turned 100 degrees to the south, following the Hudson River that would lead directly to New York City. At 08:32, the Federal Aviation Administration (FAA) Command Center in Herndon, Virginia, notified FAA headquarters.

At 08:33:59, Atta announced a third and final transmission: "Nobody move, please. We are going back to the airport. Don't try to make any stupid moves." At 08:37:08, the pilots of United Airlines Flight175 verified Flight11's location and heading to flight control. A few minutes before their plane was also hijacked, at 8:42 a.m., the pilots of Flight 175 informed New York Center that they previously heard a suspicious announcement over the radio as they were climbing out of Logan 28 minutes earlier, which would have been around the same time Flight 11 was hijacked. The pilots reported hearing the words, "Everyone, stay in your seats,"Template:R/superscript suggesting they heard the third transmission.

Fighter jets dispatched

Boston ARTCC bypassed standard protocols and directly contacted the North American Aerospace Defense Command (NORAD) Northeast Air Defense Sector (NEADS) in Rome, New York. NEADS called on two F-15 fighter jets at Otis Air National Guard Base in Mashpee, Massachusetts, to intercept. Officials at Otis spent a few minutes getting authorization for the fighters to take off. The order to dispatch the fighters at Otis was given at 08:46, and the F-15s took off at 08:53, roughly seven minutes after American Airlines Flight11 had already crashed into the North Tower. Of the four hijacked aircraft on 9/11, the nine minutes of advance notification about the hijacking of Flight11 was the most time that NORAD had to respond before the aircraft crashed into its intended target.

Crash

Jules Naudet filmed the impact of Flight 11 as it crashed into the North Tower of the World Trade Center.

At 8:37 a.m., Flight 11 began a rapid descent of 3,200 feet per minute toward New York City, gradually losing speed. Three minutes before impact, Atta completed his final turn toward Manhattan, flying south over the city in the direction of the World Trade Center. At 08:46,Template:Efn flight attendant Amy Sweeney panicked that her plane was "flying way too low" just as Atta deliberately crashed into the North Tower. The airplane, traveling about and loaded with around of jet fuel, struck the skyscraper's northern façade between floors 93 and 99, its nose impacting the 96th floor. Hundreds were killed instantly, including everyone on the aircraft and numerous workers in the North Tower. Many who had been outside of the path of the crashing airliner were incinerated as its fuel exploded.Template:R/superscript Studies suggest that as many as 1,426 people may have been present on the top 18 floors of the North Tower when it was struck almost midway into its central core.Template:Efn The core housed three stairwells (A, B and C) extending from the roof to the ground floor, with a distance of just between each one in the impact region. The size of the hijacked 767 easily severed all three, trapping close to a thousand crash survivors. All stairwells from floors 93 up to 99 were destroyed or blocked and elevator service was disrupted from the 50th floor upward.Template:R/superscript The airplane descended downward at an angle of about 10 degrees at impact, pushing rubble into stairwells as many as six stories below where it hit; consequently, the 92nd floor was also sealed off from the rest of the tower when falling debris from Flight 11's impact zone walled off each of its stairwells. The highest survivors in the North Tower came from the 91st floor, while anyone above was left to burn alive, asphyxiate, succumb to toxic exposure from ignited chemicals or be killed in the tower's eventual collapse. Some 100–200 people plummeted from the upper floors, most of whom died by jumping to escape the intense heat, smoke and flames. Light-to-moderate damage was reported on every floor from ground level to the 92nd, including collapsed walls, missing ceiling tiles, severed wires and smashed windows. The sprinkler system was severed by the impact, causing flooding on various floors throughout the tower. Moreover, burning jet fuel was channeled through the building via elevator shafts and ductwork, igniting small-scale fires on many floors between the 77th and 91st. Three major flash fires occurred in the 78th and 44th floor skylobbies as well as the main lobby at the base, causing fatal burns nearly a hundred floors below the impact. The shockwave was felt in both towers.Template:R/superscript The northern and western façades of the South Tower were battered by debris, and the explosion broke some windows in the South Tower. Prevailing winds from the northwest caused the top of the South Tower to become engulfed by the thick smoke pouring southeast, and a number of employees at that altitude reported that the fumes began filtering into their floors alongside the intense heat.

Countless people in both the city and state of New York as well as the adjacent state of New Jersey saw first-hand what had happened to the North Tower, and the smoke billowing over the horizon very quickly became visible from parts of Connecticut as well. Despite this, only four people happened to be recording at 08:46. French cameraman Jules Naudet, who was filming a documentary about the FDNY, rode with Battalion 1 to investigate a suspected gas leak in a storm drain at the intersection of Church and Lispenard streets, where he caught the only known clear footage of the plane flying into the tower. Pavel Hlava, a Czech immigrant, unknowingly taped the plane from far away while preparing to drive into the Brooklyn–Battery Tunnel from Brooklyn. Just south of the World Trade Center, the New York City-based television station WNYW had been filming in nearby City Hall Park when Flight11 crashed into the tower offscreen. Reporter Dick Oliver picked up the camera and recorded the immediate aftermath. A webcam set up by Wolfgang Staehle at an art exhibit in Brooklyn to take images of Lower Manhattan every four seconds also captured stills of Flight11 flying towards the North Tower and the explosion that followed.

Some reporters claimed that the plane that struck the North Tower was a "small, twin-engine jet," despite the size of the hole in the skyscraper. At 08:55, senior advisor to the president Karl Rove conveyed this misleading information to President George W. Bush as he arrived at Emma E. Booker Elementary School in Sarasota, Florida; the president's surmise was that the crash "must have been caused by pilot error."Template:Sfn Shortly after, in an on-air phone call from his office at the CNN New York bureau, CNN vice president of finance Sean Murtagh reported that a large passenger commercial jet had hit the World Trade Center, and other television networks began interrupting regular broadcasting with news of the crash within minutes.

The general assumption was that Flight 11's crash was a tragic accident, although some news stations suggested it could have been on purpose. Though many people in the South Tower chose to evacuate after seeing what had happened in the North Tower, the Port Authority made the decision not to initiate an immediate full-scale evacuation of the South Tower immediately following the first plane crash, operating under the assumption that it was an accident.Template:Sfn Seventeen minutes after the first impact, the World Trade Center's South Tower was hit by United Airlines Flight 175, confirming that the crash was deliberate.

Aftermath

After burning for 102 minutes, the North Tower collapsed at 10:28, 29 minutes after the South Tower's collapse.

Wreckage at museum

After the crash, the North Tower burned for 102minutes before collapsing at 10:28. Although the impact itself caused extensive structural damage, the long-lasting fire ignited by jet fuel was blamed for the structural failure of the tower. In addition to the aircraft passengers and building occupants, hundreds of rescue workers also died when the tower collapsed. Despite being the first of the two buildings to be hit, the North Tower was the second to collapse. Furthermore, it stood for nearly twice as long after being struck as the South Tower, with the latter burning for only 56 minutes before collapsing. This is because Flight 11 crashed into the North Tower at a lower speed and much higher up than Flight 175 did into the South Tower, leading to there being far less structural weight above the impact zone; the North Tower had 11 floors above the point of impact while the South Tower had more than twice that amount. Cantor Fitzgerald L.P., an investment bank on floors 101–105 of the North Tower, lost 658employees, considerably more than any other employer.

Rescue workers at the World Trade Center site began to discover body fragments from Flight11 victims within days of the attack. Some workers found bodies strapped to airplane seats and discovered the remains of a flight attendant with her hands bound, suggesting the hijackers might have used plastic handcuffs. Within a year, medical examiners had identified the remains of 33victims who had been on board Flight11. They identified two other Flight11 victims, including purser Karen Martin, in 2006, while other unrelated body fragments were discovered near Ground Zero around the same time. In April 2007, examiners using newer DNA technology identified another Flight11 victim. The remains of two hijackers, potentially from Flight11, were also identified and removed from Memorial Park in Manhattan. The remains of the other hijackers have not been identified and are buried with other unidentified remains at this park.

Suqami's passport survived the crash and landed in the street below. Soaked in jet fuel, it was picked up by a passerby who gave it to a New York City Police Department (NYPD) detective shortly before the South Tower collapsed. Investigators retrieved Mohamed Atta's luggage, which had not been loaded onto the flight. The bags contained papers from Atta's studies in Germany and Egypt; Alomari's international driver's license and passport; a videocassette for a Boeing 757 flight simulator; and a folding knife and pepper spray. They also contained "The Last Night" document, with instructions to the hijackers and preparations for martyrdom and death. Further, the bags' contents identified the names of all 19 hijackers for the four crashed, September 11 flights. In a recording, a few months later in Afghanistan, Al Qaeda's leader, Osama bin Laden, took responsibility for the attack. The attack on the World Trade Center exceeded even bin Laden's expectations: he had expected only the floors above the plane strikes to collapse. The flight recorders for Flight11 and Flight175 were never found.

The names of Flight11's crew are on Panel N-74 of the National September 11 Memorial's North Pool. The passengers' names are on that panel and four other adjacent ones.

After the attacks, the flight number for the scheduled flight on the same route with the same takeoff time was changed, and as of 2024, is flown using an Airbus A321 instead of a Boeing 767. An American flag is flown on the jet bridge of gate B32 from which Flight11 departed Logan Airport. An American flag is also flown on the jet bridge of gate 65B at Los Angeles Airport, where Flight 11 was scheduled to arrive.

In 2002, the first recipients of the annual Madeline Amy Sweeney Award for Civilian Bravery were Sweeney and Ong. Ogonowski also received a posthumous award. They were all residents of Massachusetts. Relatives of all three accepted the awards on their behalf.

On April 26, 2013, a piece of the wing flap mechanism from a Boeing 767 was discovered wedged between two buildings at Park Place, near where other landing gear parts were found. The onboard defibrillator from Flight11 was found in 2014 during roadworks near Liberty Street.

At the National September 11 Memorial, the names of the 87victims of Flight11 are inscribed on the North Pool, on Panels N-1 and N-2, and Panels N-74Template:SndN-76.
