130-547: The terrorist attacks of September 11th caused the Transportation Security Administration (TSA) to increase security measures. These increases in security multiplied the number of times travelers spent getting through the airport to their gate. After the tourism industry rebounded from the recession caused by the attacks, the higher levels of airport traffic further demonstrated the strain on these new elevated security procedures. NASA and

1170-566: A few theories that 9/11 was selected by the hijackers as the date of the attack because it resembled 9-1-1 , the phone number used to report emergencies in the United States. However, Lawrence Wright wrote that the hijackers chose the date when John III Sobieski , the King of Poland and Grand Duke of Lithuania , began the battle that turned back the Ottoman Empire 's Muslim armies that were attempting to capture Vienna in 1683. Vienna

By late June, senior counter-terrorism official Richard Clarke and CIA director George Tenet were "convinced that a major series of attacks was about to come", although the CIA believed the attacks would likely occur in Saudi Arabia or Israel. In early July, Clarke put domestic agencies on "full alert", telling them, "Something spectacular is going to happen here, and it's going to happen soon". He asked

1690-465: A period of transition, having just relocated back to Afghanistan from Sudan . The 1998 African embassy bombings and bin Laden's February 1998 fatwā marked a turning point of al-Qaeda's terrorist operation, as bin Laden became intent on attacking the United States. In late 1998 or early 1999, bin Laden approved Mohammed to go forward with organizing the plot. Atef provided operational support, including target selections and helping arrange travel for

2340-470: A telephone call mentioning the meeting, Mihdhar, and the name "Nawaf" (Hazmi); while the agency feared "Something nefarious might be afoot", it took no further action. The CIA had already been alerted by Saudi intelligence about Mihdhar and Hazmi being Al-Qaeda members. A CIA team broke into Mihdhar's Dubai hotel room and discovered that Mihdhar had a U.S. visa. While Alec Station alerted intelligence agencies worldwide, it did not share this information with

2730-974: The 9/11 Commission in April 2004, then— Attorney General John Ashcroft recalled that the "single greatest structural cause for the September 11th problem was the wall that segregated or separated criminal investigators and intelligence agents". Clarke also wrote: "[T]here were... failures to get information to the right place at the right time". Early on the morning of Tuesday, September 11, 2001, nineteen hijackers took control of four commercial airliners (two Boeing 757s and two Boeing 767s ). Large planes with long flights were selected for hijacking because they would have more fuel. * Eastern Daylight Time (UTC−04:00) Excluding hijackers Including emergency workers Including hijackers At 7:59 a.m., American Airlines Flight 11 took off from Logan International Airport in Boston .

6630-557: The U.S. Other motives have been suggested in addition to those stated by bin Laden and al-Qaeda. Some authors suggested the "humiliation" that resulted from the Islamic world falling behind the Western world—this discrepancy was rendered especially visible by globalization and a desire to provoke the U.S. into a broader war against the Islamic world in the hope of motivating more allies to support al-Qaeda. Similarly, others have argued

In a 1998 interview with American journalist John Miller , bin Laden stated: We do not differentiate between those dressed in military uniforms and civilians; they are all targets in this fatwa. American history does not distinguish between civilians and military, not even women and children. They are the ones who used bombs against Nagasaki. Can these bombs distinguish between infants and military? America does not have

Hani Hanjour ―likely while in the presence of fellow Flight 77 accomplice Nawaf al-Hazmi ―scoped out the Washington metropolitan area on July 20, 2001, by renting a plane and taking a practice flight from Fairfield, New Jersey to Gaithersburg, Maryland in order to determine the feasibility of each of the possible candidates. In the end, 19 terrorists participated in the attacks against

8190-414: The aircraft. The modus operandi of Hanjour's group was in stark contrast to the other three teams, in that while the victims were threatened with knives and box cutters, there were no reports of any injuries or deaths prior to the crash; both pilots were spared when the cockpit was breached, and the use of chemical weapons or bomb threats was not reported by either of the two people who made phone calls from

Hanjour was followed minutes later at the checkpoint by Salem and Nawaf al-Hazmi, who also set off the metal detector's alarm. The screener at the checkpoint never resolved what set off

8840-611: The alarm. As seen in security footage later released, Nawaf al-Hazmi appeared to have an unidentified item in his back pocket. Utility knives up to four inches were permitted at the time by the Federal Aviation Administration (FAA) as carry-on items. The passenger security checkpoint at Dulles International Airport was operated by Argenbright Security , under contract with United Airlines . The hijackers were all selected for extra screening of their checked bags. Hanjour, al-Mihdhar, and Moqed were chosen by

In 1996, Osama bin Laden of the Islamist militant organization al-Qaeda issued his first fatwā , which declared war against the United States and demanded the expulsion of all American soldiers from

9360-845: The attacks and said they were carried out because: The events that affected my soul in a direct way started in 1982 when America permitted the Israelis to invade Lebanon and the American Sixth Fleet helped them in that. This bombardment began and many were killed and injured and others were terrorised and displaced. I couldn't forget those moving scenes, blood and severed limbs, women and children sprawled everywhere. Houses were destroyed along with their occupants, high rises demolished over their residents, rockets raining down on our home without mercy...As I looked at those demolished towers in Lebanon, it entered my mind that we should punish

9490-468: The attacks as retaliatory strikes against American atrocities against Muslims across the world. He also maintained that the attacks were not directed against women and children, asserting that the targets of the strikes were symbols of America's "economic and military power". In bin Laden's November 2002 Letter to the American People , he identified al-Qaeda's motives for the attacks: After

9620-408: The attacks, along with Ramzi bin al-Shibh. The 2004 9/11 Commission Report determined that the animosity which Mohammed, the principal architect of the 9/11 attacks, felt towards the United States had stemmed from his "violent disagreement with U.S. foreign policy favoring Israel". Mohammed was also an adviser and financier of the 1993 World Trade Center bombing and the uncle of Ramzi Yousef ,

9750-402: The attacks, bin Laden and Ayman al-Zawahiri released additional recordings , some of which repeated the above reasons. Two relevant publications were bin Laden's 2002 Letter to the American People and a 2004 videotape by bin Laden. [...] those young men, for whom God has cleared the way, didn't set out to kill children, but rather attacked the biggest centre of military power in the world,

9880-469: The attacks, said: It has become clear that the West in general and America in particular have an unspeakable hatred for Islam.   ... It is the hatred of crusaders . Terrorism against America deserves to be praised because it was a response to injustice, aimed at forcing America to stop its support for Israel, which kills our people.   ... We say that the end of the United States is imminent, whether Bin Laden or his followers are alive or dead, for

10010-522: The awakening of the Muslim ummah [nation] has occurred.   ... It is important to hit the economy (of the United States), which is the base of its military power...If the economy is hit they will become reoccupied. Shortly before the 2004 U.S. presidential election , bin Laden used a taped statement to publicly acknowledge al-Qaeda's involvement in the attacks. He admitted his direct link to

10140-528: The boarding process a National Geographic employee took a group photograph of the teachers and students going on the Channel Islands trip and the two employees accompanying them, as well as a picture of the airplane, inadvertently capturing the last images of both the victims and N644AA. Visible in the background of the group photograph is a man whose haircut and dress shirt match that of Nawaf al-Hazmi from Dulles security footage, indicating it may also be

10270-437: The cabin's public address system, advising those aboard that the plane was being hijacked and that their best chance of survival was by not resisting. This tactic was used on Flight 11 and on Flight 93 with the aim of deceiving the passengers and crew into believing the plan was to land the plane after securing a ransom; in both cases, however, the terrorists’ understanding of the internal communication systems used aboard aircraft

10400-400: The cloud of smoke from the Pentagon. Omar Campo, another witness, was on the other side of the road: I was cutting the grass and it came in screaming over my head. I felt the impact. The whole ground shook and the whole area was full of fire. I could never imagine I would see anything like that here. Afework Hagos, a computer programmer, was on his way to work and stuck in a traffic jam near

10530-480: The congressional joint inquiry on the September ;11 attacks , said the cable reinforces questions about the thoroughness of the FBI's investigation. She also said that the inquiry concluded the hijackers had a support network that helped them in different ways. The three Qatari men were booked to fly from Los Angeles to Washington on September 10, 2001, on the same plane that was hijacked and piloted into

10660-435: The deadliest terrorist attack in history as well as the deadliest incident for firefighters and law enforcement personnel in American history, killing 343 and 72 members, respectively. The loss of life stemming from the impact of Flight 11 made it the most lethal multi-plane crash in aviation history followed by the death toll incurred by Flight 175. The destruction of the World Trade Center and its environs seriously harmed

10790-598: The deadliest terrorist attack in history. In response to the attacks, the United States waged the multi-decade global war on terror to eliminate hostile groups deemed terrorist organizations, as well as the foreign governments purported to support them. Ringleader Mohamed Atta flew American Airlines Flight 11 into the North Tower of the World Trade Center complex in Lower Manhattan at 8:46 a.m. Seventeen minutes later, United Airlines Flight 175 hit

10920-406: The eve of the attacks, after allegedly surveying the World Trade Center and the White House . U.S. law enforcement officials said the data about the four men was "just one of many leads that were thoroughly investigated at the time and never led to terrorism charges." An official added that the three Qatari citizens had never been questioned by the FBI. Eleanor Hill , the former staff director for

11050-548: The expanded use of small aircraft and community airports for public transportation. The SATS Project (2001-2006), conducted by NASA and partners in the National Consortium for Aviation Mobility (NCAM), demonstrated the technical capabilities' viability in the following four areas: September 11, 2001 attacks The September 11 attacks , commonly known as 9/11 , were four coordinated Islamist terrorist suicide attacks carried out by al-Qaeda against

11180-465: The flight 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 Pentagon in Arlington County, Virginia , killing all 64 aboard and another 125 in the building. Flight 77 became airborne at 08:20 ET . Thirty-one minutes after takeoff, the attackers stormed the cockpit and forced

11310-505: The flight, five hijackers armed with boxcutters took over the plane, injuring at least three people (and possibly killing one) before forcing their way into the cockpit. The terrorists also displayed an apparent explosive and sprayed mace into the cabin, to frighten the hostages into submission and further hinder resistance. Back at Logan, United Airlines Flight 175 took off at 8:14 a.m. Hundreds of miles southwest at Dulles International Airport , American Airlines Flight 77 left

11440-475: The four terrorists on Flight 93 ensured that Flight 77 was the only one to successfully attack a target intended by al-Qaeda when it struck the Pentagon in Arlington County , Virginia at 09:37, while a passenger uprising forced the hijackers aboard Flight 93 to crash the plane in rural Pennsylvania . Regardless, the degree of coordination between Flight 77 and Flight 93 was evidently less than that of American Airlines Flight 11 and United Airlines Flight 175 ,

11570-531: The gate at 8:00 a.m., the plane was running 42 minutes late. At 8:46 a.m., Flight 11 was deliberately crashed into the north face of the World Trade Center's North Tower between the 93rd and 99th floors. The initial presumption by many was that it was an accident. At 8:51 a.m., American Airlines Flight 77 was also taken over by five hijackers who forcibly entered the cockpit 31 minutes after take-off. Although they were equipped with knives, there were no reports of anyone on board being stabbed, nor did

11700-751: The hijackers. Bin Laden overruled Mohammed, rejecting potential targets such as the U.S. Bank Tower in Los Angeles for lack of time. Bin Laden provided leadership and financial support and was involved in selecting participants. He initially selected Nawaf al-Hazmi and Khalid al-Mihdhar , both experienced jihadists who had fought in Bosnia . Hazmi and Mihdhar arrived in the United States in mid-January 2000. In early 2000, Hazmi and Mihdhar took flying lessons in San Diego, California. Both spoke little English, performed poorly in flying lessons, and eventually served as secondary "muscle" hijackers. In late 1999,

11830-506: The hijacking of United Airlines Flight 175 commenced and the very same minute Flight 11 crashed into the North Tower of the World Trade Center. The final communication between Flight 77 and controllers on the ground occurred four minutes later at 08:50:51, as Hanjour and his team prepared to strike. The terrorists launched their assault at 08:51, by which point the North Tower had been on fire for around five minutes and Flight 175

11960-542: The impact from the crash at his home near the Pentagon. On the morning of September 11, 2001, the five hijackers arrived at Washington Dulles International Airport. At 07:15 AM ET, Khalid al-Mihdhar and Majed Moqed checked in at the American Airlines ticket counter for Flight   77, arriving at the passenger security checkpoint a few minutes later at 07:18. Both men set off the metal detector and were put through secondary screening. Moqed continued to set off

12090-459: The last photograph of any of the Flight 77 hijackers while alive, but this has not been definitely confirmed. Flight 77 was scheduled to depart for Los Angeles at 08:10; 58 passengers boarded through Gate D26, including the five hijackers. The 53 other passengers on board excluding the hijackers were 26 men, 22 women, and five children ranging in age from three to eleven. On the flight, Hani Hanjour

12220-565: The lead bomber in that attack. In late 1994, Mohammed and Yousef moved on to plan a new terrorist attack called the Bojinka plot planned for January 1995. Despite a failure and Yousef's capture by U.S. forces the following month, the Bojinka plot would influence the later 9/11 attacks. In "Substitution for Testimony of Khalid Sheikh Mohammed" from the trial of Zacarias Moussaoui , five people are identified as having been completely aware of

12350-538: The least-traveled day of the week, with the same load factor seen on Tuesdays in the previous three months for Flight   77. Passenger Barbara Olson , whose husband Theodore Olson served as the 42nd Solicitor General of the United States , was en route to a recording of the TV show Politically Incorrect . A group of three 11-year-old children, their chaperones, and two National Geographic Society staff members were also on board, embarking on an educational trip west to

12480-413: The minutes leading up to the crash, Reagan Airport controllers had asked a passing Air National Guard Lockheed C-130 Hercules to identify and follow the aircraft. The pilot, Lieutenant Colonel Steven O'Brien , told them he believed it was either a Boeing   757 or 767, observing that its silver fuselage meant it was most likely an American Airlines jet. O'Brien mentioned having difficulty picking out

12610-403: The operation's details. They are bin Laden, Khalid Sheikh Mohammed, Ramzi bin al-Shibh , Abu Turab al-Urduni and Mohammed Atef . Osama bin Laden's declaration of a holy war against the United States, and a 1998 fatwā signed by bin Laden and others that called for the killing of Americans, are seen by investigators as evidence of his motivation. In November 2001, bin Laden defended

12740-519: The oppressor in kind and that we should destroy towers in America so that they taste some of what we tasted and so that they be deterred from killing our women and children. And that day, it was confirmed to me that oppression and the intentional killing of innocent women and children is a deliberate American policy. Destruction is freedom and democracy, while resistance is terrorism and intolerance. Bin Laden personally directed his followers to attack

12870-618: The organization-including Abu Hafs the Mauritanian , Sheikh Saeed al Masri , and Sayf al Adl . One senior al Qaeda operative claims to recall Bin Ladin arguing that attacks against the United States needed to be carried out immediately to support insurgency in the Israeli-occupied territories and protest the presence of U.S. forces in Saudi Arabia. —  9/11 Commission Report , p. 251 On July 13, Tom Wilshire,

13000-471: The participant's presence in the U.S. The CIA gave Gillespie surveillance photos of Mihdhar and Hazmi from the meeting to show to FBI counterterrorism but did not tell her their significance. The Intelink database informed her not to share intelligence material with criminal investigators. When shown the photos, the FBI refused more details on their significance, and they were not given Mihdhar's date of birth or passport number. In late August 2001, Gillespie told

13130-442: The passengers and crew to the rear of the cabin, threatening the hostages but initially sparing all of them. Lead hijacker Hani Hanjour assumed control of the aircraft after having undergone extensive flight training as part of his preparation for the attack. In the meantime, two people aboard discreetly made phone calls to family members and relayed information on the situation without the knowledge of their assailants. Hanjour flew

13260-500: The phone and called the Bureau, I would have been violating the law. I would have broken the law. I would have been removed from the building that day. I would have had my clearances suspended, and I would be gone.' — Mark Rossini , The Spy Factory In December 2000, Hanjour arrived in San Diego , joining "muscle" hijackers Nawaf al-Hazmi and Khalid al-Mihdhar , who had been there since January of that year. Alec Station ,

13390-400: The phone call, she made the erroneous claim that "six persons" had forced "us" to the rear of the airplane, but did not explain whether the people crowded together were crew members, passengers, or both. May asked her mother to contact American Airlines, which she and her husband promptly did, although the company was well aware of the hijacking by this point. At 09:16, Barbara Olson made

13520-493: The phone while preparing to board their respective flights, apparently to confirm the attacks were ready to begin. The reason why al-Qaeda selected four planes from three airports instead of two airports remains unknown, but it is believed that the act of hijacking two planes on the same flight path would have enabled better coordination between the teams on Flight 11 and Flight 175, both of which clearly succeeded, unlike Flight 77 and Flight 93's only partially successful attack on

13650-462: The plane was flying northeast. He then made his wife aware of the suicide attacks on the World Trade Center, causing her to go quiet; Ted wondered if this meant she had been shocked into silence. After expressing their feelings and reassuring one another, the call cut off for the last time, at 9:26 a.m. "The speed, the maneuverability, the way that he turned, we all thought in the radar room, all of us experienced air traffic controllers, that that

13780-406: The rear of the cabin. At 08:54, as the plane flew in the vicinity over Pike County, Ohio , it began deviating from its normal assigned flight path and turned south. Two minutes later, the plane's transponder was switched off. The flight's autopilot was promptly engaged and set on a course heading eastbound towards Washington, D.C. The FAA was aware at this point there was an emergency on board

13910-530: The runway at 8:20 a.m. Flight 175's journey proceeded normally for 28 minutes until 8:42 am, when a group of five hijacked the plane, murdering both pilots and stabbing several crew members before assuming control of the aircraft. These hijackers also used bomb threats to instil fear into the passengers and crew, also spraying chemical weapons to disable any opposition. Concurrently, United Airlines Flight 93 departed from Newark International Airport in New Jersey ; originally scheduled to pull away from

14040-561: The same general area. One noteworthy difference between the attacks in the National Capital Region and those in New York is that the teams on Flights 77 and 93 did not follow suit with their counterparts on Flights 11 and 175 by booking planes from the same airport with the same California destination in mind. Flight 77's group hijacked a plane out of Dulles International Airport in Virginia, conveniently situated near

14170-546: The spring of 2001, the secondary hijackers began arriving in the United States. In July 2001, Atta met with bin al-Shibh in Tarragona , Catalonia, Spain, where they coordinated details of the plot, including final target selection. Bin al-Shibh passed along bin Laden's wish for the attacks to be carried out as soon as possible. Some of the hijackers received passports from corrupt Saudi officials who were family members or used fraudulent passports to gain entry. There have been

14300-591: The third. Seven Defense Intelligence Agency civilian employees were killed while the Office of the Secretary of Defense lost one contractor. The U.S. Army suffered 75 fatalities – 53 civilians (47 employees and six contractors) and 22 soldiers – while the U.S. Navy suffered 42 fatalities – nine civilians (six employees and three contractors) and 33 sailors. Lieutenant General Timothy Maude , an Army deputy chief of staff,

14430-511: The total flight duration was 77 minutes. The crew included Captain Charles Burlingame (51) (a Naval Academy graduate and former fighter pilot ), First Officer David Charlebois (39), purser Renee May and flight attendants Michele Heidenberger, Jennifer Lewis and Kenneth Lewis. The capacity of the aircraft was 188 passengers, but with 58 passengers on September 11, the load factor was 33 percent. American Airlines said Tuesdays were

14560-436: The two airliners that were flown into the Twin Towers of the World Trade Center 17 minutes apart in a joint attack on New York City. Flights 11 and 175 both departed from Logan International Airport in Boston for Los Angeles International Airport , and crashed into targets that stood next to each other, in contrast to the Pentagon and the federal government building Flight 93 was set to crash into, which were simply located in

14690-604: The two people who made phone calls mention the use of mace or a bomb threat. American Airlines Flight 77 38°52′16″N 77°03′29″W  /  38.87111°N 77.05806°W  / 38.87111; -77.05806 American Airlines Flight 77 was a scheduled domestic transcontinental passenger flight from Dulles International Airport in Northern Virginia to Los Angeles International Airport in Los Angeles . The Boeing 757-200 aircraft serving

14820-550: The world, which spreads mischief throughout the world. — Osama Bin Laden's interview with Tayseer Allouni , October 21, 2001 As an adherent of Islam , bin Laden believed that non-Muslims are forbidden from having a permanent presence in the Arabian Peninsula . In 1996, bin Laden issued a fatwā calling for American troops to leave Saudi Arabia. One analysis of suicide terrorism suggested that without U.S. troops in Saudi Arabia, Al-Qaeda likely would not have been able to get people to commit to suicide missions. In

14950-404: Was a military plane. You don't fly a 757 in that manner. It's unsafe." —Danielle O'Brien, air traffic controller at Dulles International Airport At 9:29 a.m., one minute after Flight 93 was hijacked, the terrorists aboard Flight 77 disengaged the autopilot and took manual control of the plane. Turning and descending rapidly as it made its final approach toward Washington, the airplane

15080-499: Was a radical who had traveled to Pakistan, and the INS arrested him for overstaying his French visa. Their request to search his laptop was denied by FBI headquarters due to the lack of probable cause . The failures in intelligence-sharing were attributed to 1995 Justice Department policies limiting intelligence-sharing, combined with CIA and NSA reluctance to reveal "sensitive sources and methods" such as tapped phones. Testifying before

15210-412: Was about to happen. None of that information got to me or the White House. [...] by July [2001], with word spreading of a coming attack, a schism emerged among the senior leadership of al Qaeda. Several senior members reportedly agreed with Mullah Omar . Those who reportedly sided with bin Ladin included Atef , Sulayman Abu Ghayth , and KSM . But those said to have opposed him were weighty figures in

15340-590: Was deliberately crashed by co-pilot Gameel Al-Batouti , killing over 200 passengers. "This is how the idea of 9/11 was conceived and developed in my head, and that is when we began the planning" bin Laden continued, adding that no one but Abu Hafs and Abu al-Khair knew about it at the time. The 9/11 Commission Report identified Khalid Sheikh Mohammed as the architect of 9/11, but he is not mentioned in bin Laden's notes. The attacks were conceived by Khalid Sheikh Mohammed , who first presented it to Osama bin Laden in 1996. At that time, bin Laden and Al-Qaeda were in

15470-411: Was described as being the "principal architect" of the attacks in the 9/11 Commission Report, al-Qaeda was motivated by several factors, not least of which was anti-Americanism and anti-Western sentiment. Because al-Qaeda only had the resources to commandeer four passenger jets, there was disagreement between Mohammed and Osama bin Laden over which targets should be prioritized. Mohammed favored striking

15600-409: Was detected again on radar screens by controllers at Dulles, who mistook it for a military fighter at first glance due to its high speed and maneuvering. While Flight   77 was 5 miles (8.0 km) west-southwest of the Pentagon in Arlington County, Virginia , it made a 330-degree spiral turn clockwise. By the end of the revolution, the 757 was descending 2,200 feet (670 m), pointed toward

15730-491: Was developed by industry from around the world. These new aircraft appear to be economically and operationally viable for use in on-demand transportation fleet operations. The first fleet operators began services in 2005, with increasing numbers of companies starting operations in 2006 and 2007. The greatest barriers were perceived to be a poor safety record for small aircraft operating from general aviation airports, restricted airspace capacity, and weather-related complications to

15860-457: Was driving on Washington Boulevard when he witnessed the crash: I looked out my window and I saw this plane, this jet, an American Airlines jet, coming. And I thought, 'This doesn't add up, it's really low.' And I saw it. I mean it was like a cruise missile with wings. It went right there and slammed right into the Pentagon. Terrance Kean, who lived in a nearby apartment building, heard the noise of loud jet engines, glanced out his window, and saw

15990-485: Was evidently not as good as Hanjour's, as they keyed the wrong microphone and broadcast their message to the ground instead. No passengers aboard Flight 11 reported hearing any intercom messages. Two people on board the aircraft made a total of three phone calls to contacts on the ground. At 09:12, flight attendant Renee May made a phone call lasting just under two minutes to her mother, Nancy May, in Las Vegas. During

16120-537: Was going to the United Arab Emirates to work for an airline. Hanjour likely went to Afghanistan, where Al-Qaeda recruits were screened for special skills they might have. Already having selected the Hamburg cell members, Al Qaeda leaders selected Hanjour to lead the fourth team of hijackers. 'I guess I was the more senior agent. So I went up to the individual that had the ticket on the Yemeni cell,

16250-551: Was killed during a U.S. military raid on his compound in Abbottabad, Pakistan . The War in Afghanistan continued for another eight years until the agreement was made in February 2020 for American and NATO troops to withdraw from the country . Excluding the hijackers, the attacks killed 2,977 people, injured thousands more and gave rise to substantial long-term health consequences while also causing at least $ 10   billion in infrastructure and property damage. It remains

16380-489: Was planning to be in Las Vegas for a friend's birthday on September 13, and initially insisted on traveling to Rome's Los Angeles studio on the 11th. However, this did not work for the show, which wanted him to travel on the day of the show. After a Rome staffer personally assured Thompson he would be able to travel from Los Angeles to Las Vegas immediately after the show, Thompson changed his travel plans. He would later feel

16510-503: Was seated up front in 1B, while Salem and Nawaf al-Hazmi were likewise seated in first class, in seats 5E and 5F. Majed Moqed and Khalid al-Mihdhar were seated farther back in 12A and 12B, in economy class. Flight   77 left the gate on time and took off from Runway 30 at Dulles at 08:20. The attacks were already underway by this point, as American Airlines Flight 11 had been hijacked six minutes earlier. Shortly after Flight 77 became airborne, FAA flight controller Danielle O'Brien made

16640-445: Was the highest-ranking military officer killed at the Pentagon; also killed was retired Rear Admiral Wilson Flagg , a passenger on the plane. LT Mari-Rae Sopper , JAGC, USNR, was also on board the flight, and was the first Navy Judge Advocate ever to be killed in action. Another 106 were injured on the ground and were treated at area hospitals. "I don't want to alarm anybody right now, but apparently – it felt just

16770-809: Was the seat of the Holy Roman Empire and Habsburg monarchy , both major powers in Europe at the time. For Osama bin Laden, this was a date when the West gained some dominance over Islam, and by attacking on this date, he hoped to make a step in Islam "winning" the war for worldwide power and influence. In late 1999, al-Qaeda associate Walid bin Attash ("Khallad") contacted Mihdhar and told him to meet in Kuala Lumpur , Malaysia; Hazmi and Abu Bara al Yemeni would also be in attendance. The NSA intercepted

16900-467: Was within 12 minutes of striking the South Tower. Flight 93 had also become airborne from Newark at 08:42, but had been delayed on the runway for as long as 42 minutes and would not be seized until 09:28, preventing al-Qaeda's idea to synchronize its takeover with that of Flight 77. Three minutes after the hijacking began, according to the commission, the attackers on Flight 77 were in full control of
