Who carried out the World Trade Center hijacking?
War in Afghanistan (2001–present)
On the morning of 11 September 2001, a total of 19 Arab men—15 of whom were from Saudi Arabia—carried out four coordinated attacks in the United States. Four commercial passenger jet airliners were hijacked. The hijackers – members of al-Qaeda's Hamburg cell – intentionally crashed two of the airliners into the Twin Towers of the World Trade Center in New York City, killing everyone on board and more than 2,000 people in the buildings. Both buildings collapsed within two hours from damage related to the crashes, destroying nearby buildings and damaging others. The hijackers crashed a third airliner into the Pentagon in Arlington, Virginia, just outside Washington, D.C. The fourth plane crashed into a field near Shanksville, in rural Pennsylvania, after some of its passengers and flight crew attempted to retake control of the plane, which the hijackers had redirected toward Washington, D.C., to target the White House, or the U.S. Capitol. No one aboard the flights survived. According to the New York State Health Department, the death toll among responders including firefighters and police was 836 as of June 2009. Total deaths were 2,996, including the 19 hijackers.
World Trade Center (1973–2001)
Yousef fled to Pakistan after the bombing but was arrested in Islamabad in , and was extradited back to the United States to face trial. Sheikh Omar Abdel Rahman was convicted in 1996 for involvement in the bombing and other plots. Yousef and Eyad Ismoil were convicted in for their carrying out the bombing. Four others had been convicted in for their involvement in the 1993 bombing. According to a presiding judge, the conspirators' chief aim at the time of the attack was to destabilize the north tower and send it crashing into the south tower, toppling both landmarks.
Ahmed Ajaj
Incarcerated from September 2, 1992, Ajaj remained in contact with Yousef and other co-conspirators and continued to be involved in the World Trade Center bombing plot. Ajaj never contacted Yousef directly. Calls were patched through "Big 5 Hamburgers" in Dallas, rendering law enforcement detection more difficult. The calls were not translated until long after the WTC bombing.
Hijackers in the September 11 attacks
The passport of Satam al-Suqami was reportedly recovered "a few blocks from where the World Trade Center's twin towers once stood"; a passerby picked it up and gave it to a NYPD detective shortly before the towers collapsed. The passports of two other hijackers, Ziad Jarrah and Saeed al-Ghamdi, were recovered from the crash site of United Airlines Flight 93 in Pennsylvania, and a fourth passport, that of Abdulaziz al-Omari was recovered from luggage that did not make it onto American Airlines Flight 11.
Ramzi Yousef
The World Trade Center bombing was a terrorist attack that occurred on 26 February 1993, when a car bomb was detonated below Tower One of the World Trade Center in New York City, New York. The 1,500 lb (680 kg) urea nitrate-hydrogen gas enhanced device was intended to knock the North Tower (Tower 1) into the South Tower (Tower 2), to bring both towers down and kill thousands of people. It failed to do so, but killed six civilians and injured 1,042, including 919 civilians (including an EMS worker), 88 firefighters, and 35 police officers.
Fred Burton (security expert)
While with the DSS, Burton was appointed by Washington to assist in the investigation of the assassination of Israeli Prime Minister Yitzhak Rabin. He also investigated the killing of Rabbi Meir Kahane; the al Qaeda New York City bombing plots before the September 11 attacks; and the Libyan-backed terrorist attacks against diplomats in Sana'a and Khartoum. He was involved in the arrest of Ramzi Yousef, the mastermind of the first World Trade Center bombing in 1993.
Mohamed Atta
Mohamed Mohamed el-Amir Awad el-Sayed Atta ( ; ""  ; September 1, 1968 – September 11, 2001) was an Egyptian hijacker and one of the ringleaders of the September 11 attacks in which four United States commercial aircraft were commandeered with the intention of destroying specific civilian targets. He served as the hijacker-pilot of American Airlines Flight 11 and crashed the plane into the North Tower of the World Trade Center as part of the coordinated attacks. At 33 years of age, he was the oldest of the 19 hijackers who took part in the attacks.
Suicide weapon
Kamikaze attacks were mimicked in the September 11, 2001 attacks, in which a group of mostly Saudi terrorists destroyed the World Trade Center and part of the Pentagon by flying hijacked jet airliners into them. It was the first and only time in history that hijacked jet airliners filled with fuel were used as cruise missiles against targets of such magnitude.
American Airlines Flight 11
American Airlines Flight 11 was a domestic passenger flight that was hijacked by five al-Qaeda members on September 11, 2001, as part of the September 11 attacks. Mohamed Atta deliberately crashed the plane into the North Tower of the World Trade Center in New York City, killing all 92 people aboard and an unknown number in the building's impact zone. The aircraft involved, a Boeing 767-223ER, registration was flying American Airlines' daily scheduled morning transcontinental service from Logan International Airport in Boston to Los Angeles International Airport in Los Angeles.
List of operations conducted by SEAL Team Six
On October 7, 1985 an Italian cruise ship Achille Lauro carrying 400 passengers including American citizens was hijacked by Palestinian terrorists led by Mohammed Abul al-Abbas also known as Muhammad Zaidan. The ship was hijacked in the Mediterranean sea and forced to sail to Southern Syria. President Ronald Reagan approved deployment of Navy’s SEAL Team SIX and Delta Force operators to plan and prepare for a rescue attempt to free the vessel from its hijackers. On October 8, Syria refused permission for the ship to dock and subsequently the hijackers murdered Leon Klinghoffer, an elderly Jewish American businessman. The ship then sailed towards Port Said, Egypt. On October 9, SEAL Team SIX assault members embarked on board the USS Iwo Jima LPH-2 which steamed for Port Said. On October 10, the four terrorist hijackers boarded an Egypt Air Boeing 737 airliner and flew from Cairo and headed for Tunisia. President Reagan approved military plans to intercept the aircraft over the Mediterranean Sea. Navy F-14 Tomcat fighters located the airliner south of Crete and forced the pilots to land at NAS Sigonella, the NATO air base in Sicily. After the 737 touched down, two United States Air Force C-141 Starliftercargo planes landed with SEAL Team SIX who quickly surrounded the airplane but were then surrounded by Italian Carabinieri. The plane came to a stop on the Italian controlled portion at Sigonella and therefore was on Italian Soil. As the SEALs prepared to assault the airplane, negotiations between the United States, Egyptian and Italian authorities continued. The four hijackers were eventually taken off the plane into the custody of the Italians without further escalation of hostilities.
American Airlines Flight 11
The 9/11 Commission estimated that the hijacking began at 08:14, when the pilots stopped responding to requests from the Boston Air Route Traffic Control Center (Boston ARTCC). It is believed that Waleed al-Shehri made the first move. 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. It is believed that Captain Ogonowski was stabbed to death in order for the hijacker pilot Mohamed Atta to take control of the plane and crash it into the North Tower of the World Trade Center. Before dying, Ogonowski keyed the cockpit microphone; "pushing its button intermittently to signal that something was wrong and at one point allowing them to hear the voice of the hijacker." At 08:16, the aircraft leveled off at and shortly thereafter deviated from its scheduled path. Boston ARTCC made multiple attempts to talk to Flight 11 without reply, and at 08:21, the flight stopped transmitting its Mode-C transponder signal.
Siraj Wahhaj
Wahhaj was one of 170 people identified by US Attorney Mary Jo White in 1995 as "unindicted persons who may be alleged as co-conspirators" in the 1993 World Trade Center bombing, but was never charged, and denies any involvement with the bombing. 
Wahhaj was a defence witness at the trial of the Blind Sheikh, Omar Abdel-Rahman, the former leader of the Egyptian terrorist organization, Gama'a al-Islamiyya.
Al-Qaeda
The September 11 attacks on America by al-Qaeda, killed 2,977 people, including 2,507 civilians, 343 firefighters, 72 law enforcement officers, and 55 military personnel. Two commercial airliners were deliberately flown into the twin towers of the World Trade Center, a third into the Pentagon, and a fourth, originally intended to target either the United States Capitol or the White House, crashed in a field in Stonycreek Township near Shanksville, Pennsylvania. It was also the deadliest foreign attack on American soil since the Japanese attack on Pearl Harbor on December 7, 1941.
Neerja Bhanot
The hijackers were part of the Abu Nidal Organization, a Palestinian terrorist organization backed by Libya; they were targeting Americans and American assets. In the early minutes of the hijacking, they identified an Indian-American citizen, dragged him to the exit, shot him dead and threw his body on to the tarmac. The terrorists then instructed Bhanot to collect the passports of all the passengers so that they could identify the other Americans on board. She and the other attendants under her charge hid the passports of the remaining 43 Americans on board; some under a seat and the rest down a rubbish chute so that the hijackers could not differentiate between American and non-American passengers.
History of the United States (1991–2008)
On the morning of September 11, 2001, four airliners were hijacked by 19 members of the terrorist organization al-Qaeda. The first hijacked airliner, American Airlines Flight 11, struck the North Tower of the World Trade Center at 8:46 A.M. (EST) in New York City; with a second, United Airlines Flight 175, striking the South Tower less than twenty minutes later at 9:03 A.M. (EST), resulting in the collapse of both 110 story skyscrapers, and the destruction of the World Trade Center. The third hijacked plane, American Airlines Flight 77, was crashed into the Pentagon (the headquarters of the United States Department of Defense) in Arlington County, Virginia, demolishing a section of the outer southwest facing wall. After discovering that their plane, United Airlines Flight 93, was going to be used as a missile, passengers attempted to regain control of the plane which had been redirected towards Washington, D.C. However, after regaining control from the hijackers, the plane crashed near a rural community near Shanksville, Pennsylvania. In total, the attacks killed 2,996 people—2,507 civilians, 343 firefighters, 72 law enforcement officers, 55 military personnel, and the 19 terrorists. The 9/11 attack was the single deadliest international terrorist incident and the most devastating foreign attack on American soil since the Japanese surprise attack on Pearl Harbor on December 7, 1941. It refocused American attention to a long war on terrorism, beginning with an attack on al-Qaeda and its Taliban supporters in Afghanistan.
Abdul Rahman Yasin
Abdul Rahman Yasin (; born April 10, 1960) is an Iraqi-American fugitive who helped make the bombs used in the 1993 World Trade Center bombing attack. He has been characterized in the American media as "the only participant in the first attempt to blow up the World Trade Center in 1993 who was never caught." Yasin's whereabouts remain unknown.
History of the Middle East
One of these Arab militants was a wealthy Saudi Arabian named Osama bin Laden. After fighting against the Soviets in Afghanistan in the 1980s, he formed the al-Qaida organization, which was responsible for the 1998 U.S. embassy bombings, the USS "Cole" bombing and the September 11, 2001 attacks on the United States. The September 11 attacks led the George W. Bush administration to invade Afghanistan in 2001 to overthrow the Taliban regime, which had been harbouring Bin Laden and al-Qaida. The United States and its allies described this operation as part of a global "War on Terror".
New York City landmark bomb plot
After the World Trade Center bombing, the Federal Bureau of Investigation had a confidential informant, Emad Salem, infiltrate the group of plotters. FBI officers arrested the main suspects in June 1993 before the plot could be carried out. In 1995, ten defendants were convicted of 48 charges related to the plot.
2001 world oil market chronology
September 11 The largest terrorist attack in world history occurs as 2 hijacked airplanes crash into the twin towers of the World Trade Center in New York City, one hijacked plane crashes into the U.S. Department of Defense's Pentagon headquarters, and another hijacked plane crashes into a rural part of Pennsylvania. The World Trade Center is destroyed, and the Pentagon is heavily damaged. Thousands of people die and economic damage is estimated to be in the billions. Aviation is halted in the United States and all major trading markets (including energy) are closed for the remainder of the week. In Europe, October Brent prices briefly touch $31.05, up from $27.59 the day before. A one-hour trading suspension follows, after which prices start to fall back. The U.S. government blames the attack on Osama Bin Laden's terrorist network (NYT)
1993 World Trade Center bombing
In March 2008, the Pentagon released its study of some 600,000 documents captured in Iraq after the 2003 invasion (see 2008 Pentagon Report). The study "found no 'smoking gun' (i.e., direct connection) between Saddam's Iraq and al Qaeda." Among the documents released by the Pentagon was a captured audio file of Saddam Hussein speculating that the 1993 attack on the World Trade Center had been carried out by Israel or American intelligence, or perhaps a Saudi or Egyptian faction. Saddam said that he did not trust the bomber Yasin, who was in Iraqi custody, because his testimony was too "organized." The Pentagon study found that Yasin "was a prisoner, and not a guest, in Iraq." Mylroie denied that this was proof of Saddam's non-involvement, claiming that "one common purpose of such meetings was to develop cover stories for whatever Iraq sought to conceal."
American Airlines Flight 77
On the morning of September 11, 2001, the five hijackers arrived at Washington Dulles International Airport. At 07:15, 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 the alarm, so he was searched with a hand wand. The Hazmi brothers checked in together at the ticket counter at 07:29.[Hani Hanjour checked in separately and arrived at the passenger security checkpoint at 07:35. 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 the alarm. As seen in security footage later released, Nawaf 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.
History of New York City (1978–present)
On September 11, 2001, Islamic terrorist hijackers linked to the jihadist organization Al-Qaeda piloted two hijacked passenger airliners into each of the twin 110 story World Trade Center towers. The airplanes, designated for transcontinental flights and therefore fully loaded with jet fuel, were hijacked mid-flight and intentionally crashed into the towers in the early morning hours of September 11. The crashes caused massive structural damage during impact, ripping gaping holes into the towers, and ignited raging fires, that caused both weakened towers to collapse in less than two hours. Together with a simultaneous attack on the Pentagon in Arlington, Virginia, and a failed plane hijacking that resulted in a plane crash in Shanksville, Pennsylvania, 2,977 victims died in the attacks.
United Airlines Flight 93
Tom Burnett made several phone calls to his wife beginning at 09:30:32 from rows 24 and 25, though he was assigned a seat in row 4. Burnett explained that the plane had been hijacked by men claiming to have a bomb. He also said that a passenger had been stabbed with a knife and that he believed the bomb threat was a ruse to control the passengers. During one of Tom Burnett's calls, his wife informed him of the attacks on the World Trade Center and he replied that the hijackers were "talking about crashing this plane. ... Oh my God. It's a suicide mission." He began asking her for information about the attacks, interrupting her from time to time to tell the others nearby what she was saying. Then he hung up. He ended his last call by saying, "Don't worry, we're going to do something." An unknown flight attendant attempted to contact the United Airlines maintenance facility at 09:32:29. The call lasted 95 seconds, but was not received as it may have been in queue. Flight attendant Sandra Bradshaw called the maintenance facility at 09:35:40 from row 33. She reported the flight had been hijacked by men with knives who were in the cabin and flight deck and had stabbed another flight attendant, possibly Debbie Welsh.
Mark Bingham called his mother at 09:37:03 from row 25. He reported that the plane had been hijacked by three men who claimed to have a bomb. Jeremy Glick called his wife at 09:37:41 from row 27 and told her the flight was hijacked by three dark-skinned men who looked "Iranian", wearing and wielding knives. Glick remained connected until the end of the flight. He reported that the passengers voted whether to "rush" the hijackers. The United air traffic control coordinator for West Coast flights, Alessandro "Sandy" Rogers, alerted the Federal Aviation Administration (FAA) Herndon Command Center in Herndon, Virginia, that Flight 93 was not responding and was off course. A minute later, the transponder was turned off, but the Cleveland controller continued to monitor the flight on primary radar. The Herndon Center relayed information on Flight 93 to FAA headquarters. Joseph DeLuca called his father at 09:43:03 from row 26 to inform him the flight had been hijacked. Todd Beamer attempted to call his wife from row 32 at 09:43:48, but was routed to GTE phone operator Lisa D. Jefferson. Beamer told the operator that the flight was hijacked and that two people who he thought were the pilots were on the floor dead or dying. He said one of the hijackers had a red belt with what looked to be a bomb strapped to his waist. When the hijackers veered the plane sharply south, Beamer briefly panicked, exclaiming, "We're going down! We're going down!" Dahl continued to struggle in the cockpit, refusing to allow a hijacker to engage the autopilot for their target, Washington, D.C. The hijackers were heard to say "Inform them, and tell him to talk to the pilot; bring the pilot back", possibly referring to Homer (CVR transcripts). A United employee in San Francisco sent an ACARS message to the flight at 09:46, "Heard report of incident. Plz confirm all is normal." Linda Gronlund called her sister, Elsa Strong, at 09:46:05 and left her a message saying there were "men with a bomb."
Flight attendant CeeCee Lyles called her husband at 09:47:57 and left him a message saying the plane had been hijacked. Marion Britton called her friend, Fred Fiumano, at 09:49:12. Fiumano recalled, "she said, 'We're gonna. They're gonna kill us, you know, We're gonna die.' And I told her, 'Don't worry, they hijacked the plane, they're gonna take you for a ride, you go to their country, and you come back. You stay there for vacation.' You don't know what to say—what are you gonna say? I kept on saying the same things, 'Be calm.' And she was crying and ... screaming and yelling." Flight attendant Sandra Bradshaw called her husband at 09:50:04 and told him she was heating water to throw at the hijackers. Passenger Lauren Grandcolas called her husband twice, once before takeoff and once during the hijacking. He missed both of her calls. She then passed her phone to Honor Elizabeth Wainio. Wainio called her stepmother at 09:53:43 and concluded, four and a half minutes later, by saying, "I have to go. They're breaking into the cockpit. I love you." Jarrah dialed in the VHF omnidirectional range (VOR) frequency for the VOR navigational aid at Reagan National Airport at 09:55:11 to direct the plane toward Washington, D.C. Bradshaw, on the phone with her husband, said "Everyone is running up to first class. I've got to go. Bye." Beamer told Jefferson that the group was planning to "jump on" the hijackers and fly the plane into the ground before the hijackers' plan could be followed through. Beamer recited the Lord's Prayer and the 23rd Psalm with Jefferson, prompting others to join in. Beamer requested of Jefferson, "If I don't make it, please call my family and let them know how much I love them." After this, Jefferson heard muffled voices and Beamer answering, "Are you ready? Okay. Let's roll." These were Beamer's last words to Jefferson.
September 11 attacks advance-knowledge conspiracy theories
There have also been allegations that the hijackers' preparations may have been given assistance by U.S. intelligence. According to CBS News, "two of the Sept. 11 hijackers who lived in San Diego in 2000 rented a room from a man who reportedly worked as an undercover FBI informant... the FBI informant prayed with them and even helped one open a bank account." Doubts have been raised about the speed with which the hijackers were identified, leading to suggestions that the FBI already had the names of the hijackers in advance. In his book "Against All Enemies", Richard Clarke said that at 9:59 am on September 11, which is the time when WTC2 collapsed and 8 minutes before NORAD even knew Flight 93 had been hijacked, the FBI already had a list of the 19 alleged hijackers. A former high-level intelligence official said that "Whatever trail was left was left deliberately—for the F.B.I. to chase."
Nawaf al-Hazmi
On September 10, 2001, Hazmi, along with Mihdhar and Hanjour checked into a hotel in Herndon, Virginia. The next morning, Hazmi and four other terrorists, boarded American Airlines Flight 77 at Dulles Airport and hijacked the plane so that Hani Hanjour could pilot and crash the plane into the Pentagon as part of the September 11 attacks. The crash killed all 64 passengers aboard the aircraft and 125 in the Pentagon. Hazmi was initially dismissed as a "muscle hijacker" following the attacks, but was later revealed to have played a larger role in the operational planning than previously believed. His younger brother, Salem al-Hazmi, was another of the hijackers aboard the same flight.
United 93 (film)
Meanwhile, newly promoted FAA National Operations Manager Ben Sliney is in a meeting when it is reported that American Airlines Flight 11 from Boston to Los Angeles has been hijacked after Mohamed Atta is overheard on the radio saying "We have some planes". Minutes later the aircraft crashes into the North Tower of the World Trade Center. Much to Sliney and his staff's horror, they learn that a second flight, United Airlines Flight 175 also from Boston to Los Angeles, has been hijacked, and after New York air traffic controllers attempt to contact the aircraft, it is seen live on CNN plowing into the South Tower of the World Trade Center. Sliney and his staff realize they are dealing with several hijackings and order the military to be on the lookout for American Airlines Flight 77, which is reported missing and presumed to have also been hijacked.
Urban terrorism
The September 11 attacks (often referred to as September 11th or 9/11) were a series of coordinated suicide attacks by al-Qaeda. On that morning, 19 al-Qaeda terrorists hijacked four commercial passenger jet airliners. The hijackers intentionally crashed two of the airliners into the Twin Towers of the World Trade Center in New York City, killing everyone on board and many others working in the buildings. Both buildings collapsed within two hours, destroying nearby buildings and damaging others. The hijackers crashed a third airliner into the Pentagon in Arlington, Virginia, just outside Washington, D.C. The fourth plane crashed into a field near Shanksville in rural Pennsylvania after some of its passengers and flight crew attempted to retake control of the plane, which the hijackers had redirected toward Washington, D.C. in an attempted attack on the United States Capitol Building. There were no survivors from any of the flights.
The Third Terrorist
"One indicator that this terrorist act had broader implications came directly from Abdul Hakim Murad, Yousef's roommate, childhood friend, and fellow convicted
terrorist. On the day of the bombing, Murad claimed responsibility for this terrorist act from his jail cell in New York. He bragged to his prison guards, verbally and in writing, that the bombing of the Murrah federal building was the work of the "Liberation Army." His confession was similar to the one Yousef had made two years earlier in the immediate aftermath of the first attempt to destroy the World Trade Center. Hours after he drove a Ryder truck into the garage of the north tower of the World Trade Center and detonated the deadly bomb, Yousef called the FBI from a pay phone in Newark International Airport and boasted that the "Liberation Army" had conducted the attack. He then boarded a plane and escaped, ending up in Manila, Philippines. Note: the Oklahoma City Bombing followed a similar pattern to the 1993 attack on the World Trade Center —a rental truck loaded with ammonium-based explosives, using similar detonation devices, based on the strategy of driving a vehicle into or near a target."
Ahmed al-Ghamdi
On the morning of September 11, 2001, Ahmed left the hotel with Hamza, the two of them sharing a taxicab to get to Logan International Airport. There, Ghamdi showed his Virginia ID Card as identification, and boarded Flight 175 where he sat the furthest back of the hijackers, in seat 9D, helped to hijack it, and assisted as the plane crashed into the World Trade Center. Ahmed and Hamza al-Ghamdi pushed the passengers and crew to the back of the plane while Fayez Banihammad and Mohand al-Shehri killed the pilots Victor Saracini and Michael Horrocks allowing Marwan al-Shehhi to take control of the plane.
Responsibility for the September 11 attacks
Intelligence experts speak of a "short list" of prime suspects—groups that possess both the means and the motive to carry out the crime. Two of the passengers had been identified as al-Qaeda members and were on the FBI's terrorist-alert list prior to 9/11: Khalid Almihdhar and Nawaf Alhazmi. It appears certain that all hijackers had Arab origins, and none were Afghan; moreover, both in their immense scale, careful planning and refraining from claiming responsibility, the attacks are reminiscent of al-Qaeda's previous attacks such as the 1998 US embassy bombings that killed over 200 people.
One World Trade Center
At 8:46 a.m. (EDT) on September 11, 2001, five hijackers affiliated with al-Qaeda crashed American Airlines Flight 11 into the northern facade of the North Tower between the 93rd and 99th floors. Seventeen minutes later, at 9:03 a.m. (EDT), a second group of terrorists crashed the hijacked United Airlines Flight 175 into the southern facade of the South Tower, striking between the 77th and 85th floors.
Outline of the September 11 attacks
On the morning of September 11, 2001, 19 al-Qaeda terrorists hijacked four commercial passenger jet airliners, intentionally crashing two into the World Trade Center in New York City. The hijackers crashed a third airliner into the Pentagon. The fourth plane crashed in a field near Shanksville, Pennsylvania. Nearly 3,000 victims and the 19 hijackers died in the attacks.
The leader of al Qaeda, Osama bin Laden, eventually claimed responsibility for the attacks.The United States launched the War on Terror, invading Afghanistan.The US enacted the USA PATRIOT Act. Many other countries also strengthened their anti-terrorism legislation and expanded law enforcement powers.Some American stock exchanges stayed closed for the rest of the week following the attack and posted enormous losses on reopening, especially in the airline and insurance industries. The destruction of billions of dollars' worth of office space caused serious damage to the economy of Lower Manhattan.The Pentagon Memorial was built adjacent to the building. The rebuilding process has started on the World Trade Center site. In 2006, a new office tower was completed on the site of 7 World Trade Center. The new One World Trade Center was later built and was completed in 2014. Three more towers were originally expected to be built between 2007 and 2012 on the site, but are now delayed to 2018. Ground was broken for the Flight 93 National Memorial on November 8, 2009, and the first phase of construction is expected to be ready for the 10th anniversary of the attacks on September 11, 2011.
Robert Baer
Baer wrote about the events of the September 11, 2001 terrorist attacks in "The Guardian" "[D]id bin Laden act alone, through his own al-Qaida network, in launching the attacks? About that I'm far more certain and emphatic: no." He later stated, "For the record, I don't believe that the World Trade Center was brought down by our own explosives, or that a rocket, rather than an airliner, hit the Pentagon. I spent a career in the CIA trying to orchestrate plots, wasn't all that good at it, and certainly couldn't carry off 9/11. Nor could the real pros I had the pleasure to work with."
Abdulaziz al-Omari
In the early hours of September 11, they boarded a commuter flight back to Boston to connect to American Airlines Flight 11. American 11 was hijacked 15 minutes after the flight departed by Omari and four other hijackers, which allowed trained pilot Mohamed Atta to crash the Boeing 767 into the North Tower of the World Trade Center as part of an attack that killed thousands of people.
The Third Terrorist
Representative Dana Rohrabacher (R - CA) cited this research in the report "The Oklahoma City Bombing: Was There A Foreign Connection?" Within the report the following statements citing several pieces of real and circumstantial evidence were made, supporting the main theory laid out by Jayna Davis in her book. "...of all the cities in the world, convicted terrorist Ramzi Yousef and
Terry Nichols were in Cebu City in the Philippines at the same time three months before the Oklahoma City bombing. Yousef was the perpetrator of the first World Trade Center attack as well as the mastermind behind the planning of other high-profile attacks on Americans. Furthermore, Ramzi Yousef's phone records, from the months before he detonated the first World Trade Center bomb in early 1993, show calls placed to the Filipina neighbor and close friend of Terry Nichols' in-laws in Queens, New York. The opportunity for interaction between American terrorist, Nichols, and al-Qaeda terrorist, Yousef, is evident."
Leonard W. Hatton Jr.
Leonard William Hatton Jr. (August 16, 1956 – September 11, 2001) was an American special agent of the Federal Bureau of Investigation (FBI). He was killed in the September 11 terrorist attacks on the World Trade Center in New York City when he entered one of the towers to help evacuate the occupants and stayed when the towers collapsed.
Terrorism
This strategy was used by Al-Qaeda in its attacks on the World Trade Center and the Pentagon in the United States on September 11, 2001. These attacks are also used to draw international attention to struggles that are otherwise unreported, such as the Palestinian airplane hijackings in 1970 and the 1975 Dutch train hostage crisis.
9/11 Commission Report
In addition to identifying intelligence failures occurring before the attacks, the report provided evidence of the following:The commission also concluded 15 of the 19 hijackers who carried out the attacks were from Saudi Arabia, but the commission "found no evidence that the Saudi government as an institution or senior Saudi officials individually funded the organization" to conspire in the attacks, or that it funded the attackers even though the "report identifies Saudi Arabia as the primary source of al-Qaeda funding". (A 28-page section of an earlier, different 9/11 report included claims of greater Saudi involvement, but "did not withstand deeper scrutiny" by the Commission.)
Mohamed Atta, the leader of the attacks, was from Egypt. Two hijackers were from the United Arab Emirates, and one was from Lebanon. According to the commission, all 19 hijackers were members of the al-Qaeda terrorist organization, led by Osama bin Laden. In addition, while meetings between al-Qaeda representatives and Iraqi government officials had taken place, the panel had no credible evidence that Saddam Hussein had assisted al-Qaeda in preparing or executing the 9/11 attacks.
Waleed al-Shehri
By 7:40 a.m., all five hijackers were aboard the flight, which was scheduled to depart at 7:45 a.m. Wail and Waleed al-Shehri sat together in first class in seats 2A and 2B respectively. The aircraft taxied away from Gate 26 and departed Logan International Airport at 7:59 a.m. from runway 4R after a 14-minute delay. The hijacking of Flight 11 began at approximately 08:14, which is when the pilot stopped responding to air traffic control. Once the hijacking began, the brothers are suspected of having stabbed two flight attendants. At 08:46:40, Mohamed Atta deliberately crashed Flight 11 into the northern facade of the North Tower (Tower 1) of the World Trade Center. The damage caused to the North Tower destroyed any means of escape from above the impact zone, trapping 1,344 people. The North Tower collapsed at 10:28, after burning for 102 minutes.
Bowling Green massacre
On January 29–30, 2017, White House Press Secretary Sean Spicer stated that Islamist terrorists perpetrated a terrorist attack in Atlanta, even though Atlanta has never had a terrorist attack carried out by Islamists. The initial comment was made on ABC's "This Week", and then Spicer repeated the claim on MSNBC's "Morning Joe" the following day. Spicer later said that he meant Orlando, referring to the 2016 Orlando nightclub shooting, which was carried out by U.S.–born Omar Mateen. There have been two terrorist attacks in Atlanta: the 1996 Centennial Olympic Park bombing, which was carried by domestic terrorist Eric Rudolph, and the 1958 Hebrew Benevolent Congregation Temple bombing.
Pan American World Airways
On September 6, 1970, two men hijacked Pan Am Flight 93, a Boeing 747–121 (N752PA) en route from Amsterdam to New York, as part of the Dawson's Field hijackings. The flight diverted to Beirut International Airport to take on board seven other gang members for the next leg to Cairo International Airport, where the hijackers ordered the aircraft evacuated and destroyed it with explosives.
William Rodriguez
Rodriguez also claimed to have seen hijacker Mohand al-Shehri scoping out the building prior to the attacks, in June 2001. A "Daily News" article says he told the FBI and the 9/11 Commission that he recognized the man after a brief, chance encounter months prior to the terrorist attacks. "It is believed that American Airlines Flight 11 hijacker Mohamed Atta cased New York City targets, including the Diamond District, but Rodriguez may have given the 9/11 panel the first eyewitness testimony about a hijacker inside one of the towers before the terror strike.
Wail al-Shehri
Wail Mohammed al-Shehri (, ; also transliterated as Alshehri) (July 31, 1973 – September 11, 2001) was one of five hijackers of American Airlines Flight 11, which was hijacked and flown into the North Tower of the World Trade Center as part of the September 11 attacks.
Mohamed Atta
The hijacking began at 8:14 am — 15 minutes after the flight departed — when beverage service would be starting. At this time, the pilots stopped responding to air traffic control, and the aircraft began deviating from the planned route. At 8:18 am, flight attendants Betty Ong and Madeline Amy Sweeney began making phone calls to American Airlines to report what was happening. Ong provided information about lack of communication with the cockpit, lack of access to the cockpit, and passenger injuries. At 8:24:38 am, a voice believed to be Atta's was heard by air traffic controllers, saying: "We have some planes. Just stay quiet and you will be OK. We are returning to the airport." "Nobody move, everything will be OK. If you try to make any moves you'll endanger yourself and the airplane. Just stay quiet." "Nobody move, please. We are going back to the airport. Don't try to make any stupid moves." The plane's transponder was turned off at 8:21 am. At 8:46:35 am, Atta flew the plane into the North Tower of the World Trade Center.
Fawaz al-Nashimi
On June 21, 2006, a US intelligence contractor in Virginia, IntelCenter, released a 54-minute Al-Qaeda video in which Nashimi justifies attacking the Western World. Several days before on June 13, an audio webpost supposedly from Al-Qaeda claimed that Nashimi was to have been the 20th hijacker on United Airlines Flight 93, but was unable to participate at the planned time.
Hijackers in the September 11 attacks
The hijackers in the September 11 attacks were 19 men affiliated with al-Qaeda. 15 of the 19 were citizens of Saudi Arabia, and the others were from the United Arab Emirates (2), Egypt, and Lebanon. The hijackers were organized into four teams, each led by a pilot-trained hijacker with three or four "muscle hijackers," who were trained to help subdue the pilots, passengers, and crew.
Hispanics in the United States Air Force
On September 11, 2001, United Airlines Flight 93 was hijacked by four members of al-Qaeda terrorists as part of the September 11 attacks. The hijackers breached the aircraft's cockpit and overpowered the flight crew approximately 46 minutes after takeoff. Ziad Jarrah, a trained pilot, then took control of the aircraft and diverted it back toward the east coast of the United States in the direction of Washington, D.C. The hijackers' specific target was the United States Capitol.
Kenneth O'Keefe
On Iran's Press TV program, "The Agenda", while speaking on the topic of "America: Is it a Civilized Nation?", O'Keefe denied the plausibility that the September 11 attacks were committed by Osama bin Laden and the 19 hijackers. He claimed it was an inside job and that the US government and intelligence agencies, including Mossad, were responsible. He has repeated this view in an article on his own website, in which he states "Israeli Mossad worked with high treason traitors in the US government to set explosives in the twin towers and building 7 on 9/11 so as to instigate the fraudulent 'War on Terror'".
Hijackers in the September 11 attacks
Two flight attendants called the American Airlines reservation desk during the hijacking. Betty Ong reported that "the five hijackers had come from first-class seats: 2A, 2B, 9A, 9C and 9B." Flight attendant Amy Sweeney called a flight services manager at Logan Airport in Boston and described them as Middle Eastern. She gave the staff the seat numbers and they pulled up the ticket and credit card information of the hijackers, identifying Mohamed Atta.
Richard Williamson (bishop)
Williamson supports conspiracy theories regarding the assassination of John F. Kennedy, and the World Trade Center controlled demolition conspiracy theory, denying that the September 11 attacks were foreign terrorist attacks and claiming they were instead staged by the U.S. government. He has also said that the 7 July 2005 London bombings were an "inside job" and propagated rumours about the likelihood of a nuclear attack on the London Olympics in 2012.
Al-Qaeda
In December 1998, the Director of the CIA Counterterrorism Center reported to President Bill Clinton that al-Qaeda was preparing to launch attacks in the United States, and that the group was training personnel to hijack aircraft. On September 11, 2001, al-Qaeda attacked the United States, hijacking four airliners within the country and deliberately crashing two into the twin towers of the World Trade Center in New York City. The third plane crashed into the western side of the Pentagon in Arlington County, Virginia. The fourth plane was crashed into a field in Shanksville, Pennsylvania. In total, the attackers killed 2,977 victims and injured more than 6,000 others.
Planning of the September 11 attacks
On September 11, 2001, 19 Arab-Muslim hijackers took control of four commercial aircraft and used them as suicide weapons in a series of four coordinated acts of terrorism to strike the World Trade Center in New York City, The Pentagon in Arlington County, Virginia, and an additional target in Washington, D.C. Two aircraft hit the World Trade Center while the third hit the Pentagon. A fourth plane never arrived at its target, crashing in a field in Pennsylvania after a passenger revolt. The intended target is believed to have been either the United States Capitol or the White House. As a result, 2,977 victims were killed, making it the deadliest terrorist attack on U.S. soil; also the deadliest foreign attack on U.S. soil, exceeding Japan's surprise attack on Pearl Harbor in Honolulu, Hawaii, on December 7, 1941, which killed 2,403 victims. It was carefully planned by al-Qaeda, who sent 19 terrorists to take over Boeing 757 and Boeing 767 aircraft, operated by American Airlines and United Airlines.
Abdulaziz al-Omari
Omari arrived in the United States in June 2001, on a tourist visa, obtained through the Visa Express program. On September 11, 2001, Omari boarded American Airlines Flight 11 and assisted in the hijacking of the plane, which was crashed into the North Tower of the World Trade Center, as part of the coordinated attacks.
The Lufthansa Heist
Burke, an astute criminal, selected six armed robbers from his Robert's Lounge Gang, a band of psychotic thieves with low levels of intelligence and hair-trigger tempers. On December 11, 1978 at 3:00 a.m., the gunmen forayed into Lufthansa Cargo Building 261 at Kennedy Airport and held hostage the night staff. Two of the perpetrators forced the supervisor to disarm the alarm system of the high-value vault and hauled out bundles of cash and jewels, totaling $6,000,000. (Approximately $42,000,000 at present value) 
When the robbery was reported, several law enforcement agencies swarmed into the Lufthansa Cargo Complex. The New York Port Authority Police, The New York Police Department, The Queens County District Attorney, and the FBI took immense interest in this crime of epic proportion, and an extraordinary rivalry began among them. The Lufthansa heist spun national headlines for months to follow, and every law enforcement agent wished to assume control of the investigation, hopefully to eventually taking credit for solving the crime. In fact, the competition to dominate the case became so intense that the various law enforcement agencies threw one another off course by sabotaging their investigations. The winners were the FBI and the US attorney.
But for Burke and the Robert's Lounge Gang matters became problematic when one of their accomplices, Stacks Edwards, failed to deliver the getaway van to an auto wrecking yard for it to be destroyed. Instead, he parked it near a fire hydrant and spent the night snorting cocaine with his girlfriend. The police discovered the van and lifted fingerprints that matched those of the perpetrators, who had already been under suspicion. Consequently, Jimmy Burke ordered Stacks to be murdered.
Central Intelligence Agency
In 1999, CIA chief George Tenet launched a grand "Plan" to deal with al-Qaeda. The Counterterrorist Center, its new chief Cofer Black and the center's bin Laden unit were the Plan's developers and executors. Once it was prepared Tenet assigned CIA intelligence chief Charles E. Allen to set up a "Qaeda cell" to oversee its tactical execution. In 2000, the CIA and USAF jointly ran a series of flights over Afghanistan with a small remote-controlled reconnaissance drone, the Predator; they obtained probable photos of bin Laden. Cofer Black and others became advocates of arming the Predator with missiles to try to assassinate bin Laden and other al-Qaeda leaders. After the Cabinet-level Principals Committee meeting on terrorism of September 4, 2001, the CIA resumed reconnaissance flights, the drones now being weapons-capable.On September 11, 2001, 19 Al-Qaeda members hijacked four passenger jets within the Northeastern United States in a series of coordinated terrorist attacks. Two planes crashed into the Twin Towers of the World Trade Center in New York City, the third into the Pentagon in Arlington County, Virginia, and the fourth inadvertently into a field near Shanksville, Pennsylvania. The attacks cost the lives of 2,996 people (including the 19 hijackers), caused the destruction of the Twin Towers, and damaged the western side of the Pentagon. Soon after 9/11, "The New York Times" released a story stating that the CIA's New York field office was destroyed in the wake of the attacks. According to unnamed CIA sources, while first responders, military personnel and volunteers were conducting rescue efforts at the World Trade Center site, a special CIA team was searching the rubble for both digital and paper copies of classified documents. This was done according to well-rehearsed document recovery procedures put in place after the Iranian takeover of the United States Embassy in Tehran in 1979. While it was not confirmed whether the agency was able to retrieve the classified information, it is known that all agents present that day fled the building safely.
Aircraft hijacking
On September 11, 2001, 19 al-Qaeda Islamic extremists hijacked American Airlines Flight 11, United Airlines Flight 175, American Airlines Flight 77, and United Airlines Flight 93 and crashed them into the Twin Towers of the World Trade Center, the southwestern side of the Pentagon, and Stonycreek Township near Shanksville, Pennsylvania (after passengers acted to stop the hijackers; its intended target was either the White House or the U.S. Capitol) in a terrorist attack. All in all, 2,996 people perished and more than 6,000 others were injured in the attacks. This casualty toll makes the hijackings the most fatal in history.
Ahmed Omar Saeed Sheikh
"The Wall Street Journal" was one of the only Western news organisations to follow up on the story, citing the "Times of India": "US authorities sought General Mahmud Ahmed's removal after confirming that $100,000 was wired to WTC hijacker Mohamed Atta from Pakistan by Ahmad Umar Sheikh at the insistence of General Mahmud." Another Indian newspaper, the "Daily Excelsior", quoting FBI sources, reported that the "FBI's examination of the hard disk of the cellphone company Saeed had subscribed to led to the discovery of the "link" between him and the deposed chief of the Pakistani ISI, Mahmud Ahmed. And as the FBI investigators delved deep, reports surfaced with regard to the transfer of $100,000 to Mohamed Atta, one of the ringleaders of the September 11 attacks, who flew a hijacked Boeing commercial airliner into the World Trade Center. General Mahmud Ahmed, the FBI investigators found, fully knew about the transfer of money to Atta."
Kroll Inc.
Kroll were responsible for revamping security at the World Trade Center after the 1993 World Trade Center bombing. They also took on responsibility for security at Chicago's Sears Tower following the September 11, 2001 attacks.
Just prior to the September 11 attacks, Kroll Inc., with the guidance of Jerome Hauer, at the time the Managing director of their Crisis and Consulting Management Group,
hired former FBI special investigator John P. O'Neill, who specialized in the Al-Qaeda network held responsible for the 1993 bombing, to head the security at the WTC complex. O'Neill died in the attacks.
2010 Times Square car bombing attempt
Al-Awlaki was known among other things for having spoken with three of the September 11 hijackers in 2001, for having exchanged dozens of emails with the suspected Fort Hood shooter Nidal Malik Hasan, he is believed to have met with Christmas Day bomber Umar Farouk Abdulmutallab during his training by Al Qaeda in the Arabian Peninsula, and for militant English-language online lectures and writings with violent rhetoric were a catalyst for a number of attacks. "The New York Times" described al-Awlaki as "perhaps the most prominent English-speaking advocate of violent jihad against the United States." Al-Awlaki was the first U.S. citizen killed by the CIA under a presidential decree.
Responsibility for the September 11 attacks
According to interviews by Al-Jazeera as well as United States interrogations of al-Qaeda members Ramzi bin al-Shibh and Khalid Shaikh Mohammed (captured in 2002 and 2003 respectively), Khalid Sheikh Mohammed was the instigator and prime organizer of the attacks. Bin al-Shibh may have been picked as a hijacker but he failed to get into the United States.
Hijackers in the September 11 attacks
According to the 9/11 Commission Report, 26 al-Qaeda terrorist conspirators sought to enter the United States to carry out a suicide mission. In the end, the FBI reported that there were 19 hijackers in all: five on three of the flights, and four on the fourth. On September 14, three days after the attacks, the FBI announced the names of 19 persons. After a controversy about an earlier remark, U.S. Homeland Security Secretary Janet Napolitano stated in May 2009 that the 9/11 Commission found that none of the hijackers entered the United States through Canada.
Ted Kaczynski
In 2016, it was reported that early on in his imprisonment Kaczynski had befriended Ramzi Yousef and Timothy McVeigh, the perpetrators of the 1993 World Trade Center bombing and the Oklahoma City bombing, respectively. The trio discussed religion and politics and formed a friendship which lasted until McVeigh's execution in 2001.
American Airlines Flight 11
Rescue workers at the World Trade Center site began to discover body fragments from Flight 11 victims within days of the attack. Some workers found bodies strapped to airplane seats and discovered the body 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 33 victims who had been on board Flight 11. They identified two other Flight 11 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 Flight 11 victim. The remains of two hijackers, potentially from Flight 11, 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.
United States v. Khalid Sheikh Mohammed
A rally near the federal court building in Foley Square, in lower Manhattan, was held on 5 December 2010 at which the decision to transfer the case to a civilian court was severely criticized. It was organized, in part, by Debra Burlingame, the sister of the pilot Charles Burlingame, who was killed when Al Qaeda hijackers crashed the plane he had been flying into the Pentagon. Burlingame is one of the three founders of Keep America Safe, a new political-advocacy group. Andrew McCarthy, the former Chief Assistant U.S. Attorney who led the prosecution of the 1993 World Trade Center attack, spoke at this rally declaring that Eric Holder didn't "understand what rule of law has always been in wartime." He said, "It's military commissions. It's not to wrap our enemies in our Bill of Rights."
September 11 attacks advance-knowledge conspiracy theories
On December 22, 2010, a United States Federal Judge signed a default judgment holding Iran, the Taliban and al-Qaeda liable following an open court hearing in which the evidence was produced by the plaintiffs' attorneys which they said showed that Iran assisted the hijackers. 9/11 commission members and witnesses who claimed they were Iranian defectors and members of Ministry of Intelligence and National Security and the Iranian Revolutionary Guards also testified during the hearing. The suit "Havlish, et al. v. bin Laden, et al" was brought in 2001 by Fiona Havlish whose husband died in the North Tower. Abolghasem Mesbahi, who claimed he was a former Ministry of Intelligence operative in charge of Iran's espionage operations in Western Europe testified that he was part of a task force that designed contingency plans for unconventional warfare against the United States code-named "Shaitan dar Atash"/"Satan in Flames" which included crashing hijacked passenger airliners into the World Trade Center, the Pentagon, and the White House, and that in the summer of 2001 he received three coded messages telling him to activate the plan. An Iranian government memorandum was presented as evidence that Iran's Supreme Leader Ayatollah Khamenei had pre knowledge of the attacks. Several days after the ruling a spokesperson for Iran's Foreign ministry said charges that Iran "had a hand in planning the attacks and that one of al-Qaeda's members was present inside the country is baseless" and said "With the repetition of such claims to back its political aims the U.S. is putting the peace and security of the world in jeopardy,".
Richard A. Clarke
Clarke was involved in supervising the investigation of Ramzi Yousef, one of the main perpetrators of the 1993 World Trade Center bombing, who had traveled to the United States on an Iraqi passport. Yousef is the nephew of Khalid Sheikh Mohammed, a senior al-Qaeda member. Many in the Clinton administration and the intelligence community believed Yousef's ties were evidence linking al-Qaeda's activities and the government of Iraq.
King Fahad Mosque (Culver City, California)
According to FBI documents and a CIA memo noted in a congressional report into the attacks of September 11, 2001, the hijackers Khalid al-Midhar and Nawaf al-Hazmi may have been in contact with Saudi diplomat Shaykh al-Thumairy, who was the chief imam at the King Fahad Mosque (most of the 9/11 hijackers were Saudi nationals and several were not fluent in English and had little experience living in the West). According to the congressional report, the mosque was identified by the FBI as a site of “extremist-related activity both before and after September 11”. According top the commission, “several subjects of FBI investigations prior to September 11 had close connections to the mosque and are believed to have laundered money through this mosque to nonprofit organizations overseas affiliated with Usama Bin Ladin.”
Anwar al-Awlaki
According to US sources, the strike was carried out by Joint Special Operations Command, under the direction of the CIA. A witness said the group had stopped to eat breakfast while traveling to Ma'rib Governorate. The occupants of the vehicle spotted the drone and attempted to flee in the vehicle. Yemen's Defense Ministry announced that al-Awlaki had been killed. Also killed was Samir Khan, an American born in Saudi Arabia, thought to be behind al-Qaeda's English-language web magazine "Inspire". US President Barack Obama said:
Hostage Rescue Team
Some higher-profile cases include the Waco siege; Ruby Ridge; the capture of the suspected masterminds of the 1998 bombings of the US embassies in Africa; the rescue following the 2013 abduction of a five-year-old boy in Alabama; the hostage rescue operations of prison guards at Talladega, Alabama, and St. Martinville, Louisiana; and the January 29, 2016 confrontation with militants involved in the occupation of the Malheur National Wildlife Refuge. On April 19, 2013, the Hostage Rescue Team arrested a man in Watertown, Massachusetts, after a manhunt for Dzhokhar Tsarnaev, one of two perpetrators of the Boston Marathon bombing of April 15. HRT rescued a teenager by killing her abductor on August 10, 2013. HRT rescued kidnap victim Frank Arthur Janssen. The HRT assisted in the capture of Eric Frein, the sole suspect in the 2014 Pennsylvania State Police barracks attack. The FBI HRT was deployed to the 2016 Republican National Convention and the 2016 Democratic National Convention
September 11 attacks
Immediately after the attacks, the Federal Bureau of Investigation started PENTTBOM, the largest criminal inquiry in the history of the United States. At its height, more than half of the FBI's agents worked on the investigation and followed a half-million leads. The FBI concluded that there was "clear and irrefutable" evidence linking al-Qaeda and bin Laden to the attacks.
The FBI was quickly able to identify the hijackers, including leader Mohamed Atta, when his luggage was discovered at Boston's Logan Airport. Atta had been forced to check two of his three bags due to space limitations on the 19-seat commuter flight he took to Boston. Due to a new policy instituted to prevent flight delays, the luggage failed to make it aboard American Airlines Flight 11 as planned. The luggage contained the hijackers' names, assignments, and al-Qaeda connections. "It had all these Arab-language papers that amounted to the Rosetta stone of the investigation", said one FBI agent. Within hours of the attacks, the FBI released the names and in many cases the personal details of the suspected pilots and hijackers. On September 27, 2001, they released photos of all 19 hijackers, along with information about possible nationalities and aliases. Fifteen of the men were from Saudi Arabia, two from the United Arab Emirates, one from Egypt, and one from Lebanon.
1998 Bank of America robbery
The robbery was plotted and executed by an actor and petty criminal named Ralph Guarino. Guarino received some intelligence from a WTC worker named Salvatore Calciano, who told him about the increased security that followed the 1993 World Trade Center bombing and would later give him his employee ID badge. Calciano also told Guarino when a Brink's armored truck would arrive to deliver money via elevator to the 11th floor of the North Tower (Tower One) of the WTC.
Outline of the September 11 attacks
The September 11 attacks were four coordinated suicide attacks upon the United States in New York City and the Washington, D.C., area on September 11, 2001. On that Tuesday morning, 19 terrorists from the Islamist militant group al-Qaeda hijacked four passenger jets. The hijackers intentionally crashed two planes, American Airlines Flight 11 and United Airlines Flight 175, into the Twin Towers of the World Trade Center in New York City; both towers collapsed within two hours. Hijackers crashed American Airlines Flight 77 into the Pentagon in Arlington, Virginia. The fourth jet, United Airlines Flight 93, crashed into a field near Shanksville, Pennsylvania, after passengers attempted to take control before it could reach the hijacker's intended target in Washington, D.C. Nearly 3,000 died in the attacks, and the 9/11 attacks have had broad and lasting consequences to military policy, politics, and foreign relations. Effects have also been seen in literature, film, and popular culture.
Motives for the September 11 attacks
The September 11, 2001, attacks in the northeast United States were an organized terrorist act carried out by 19 hijackers, and organized by numerous members of al-Qaeda. Motives for the attacks were stated before and after the attacks in several sources, Osama bin Laden's declaration of a holy war against the United States, and a fatwā signed by bin Laden and others for the killing of Americans in 1998, are seen by investigators as evidence of his motivation. However, in an interview with Daily Ummat, Osama bin Laden rejected Al-Qaeda's involvement in the September 11 attacks.
Mahmoud Mahmoud Atta
Following the September 11, 2001 attacks in the United States it was initially thought that Mahmoud Mahmoud Atta was one of the hijackers on board the first plane to hit the World Trade Center. This led to the harsh questioning of US immigration authorities and the intelligence community, because it was felt that they had failed to stop a known terrorist from entering the country under his true name. However, his identity was confused with the Egyptian militant leader Mohamed Atta who was actually on board the flight.
Presidency of George W. Bush
On September 11, 2001, al-Qaeda terrorists hijacked four airliners and flew two them into the twin towers of the World Trade Center in New York City, destroying both 110-story skyscrapers. Another plane crashed into Pentagon, while the final plane was brought down in Pennsylvania following a struggle between the terrorists and the aircraft's passengers. The attacks had a profound effect on many Americans, who felt vulnerable to international attacks for the first time since the end of the Cold War. Appearing on national television on the night of the attacks, Bush promised to punish those who had aided the attacks, stating, "we will make no distinction between the terrorists who committed these acts and those who harbor them." In the following days, Bush urged the public to renounce hate crimes and discrimination against Muslim-Americans and Arab-Americans. He also declared a "War on Terror", instituting new domestic and foreign policies in an effort to prevent future terrorist attacks.
War on Terror
On the morning of September 11, 2001, nineteen men hijacked four jet airliners all bound for California. Once the hijackers assumed control of the jet airliners, they told the passengers that they had a bomb on board and would spare the lives of passengers and crew once their demands were met – no passenger and crew actually suspected that they would use the jet airliners as suicide weapons since it had never happened before in history, and many previous hijacking attempts had been resolved with the passengers and crew escaping unharmed after obeying the hijackers. The hijackers – members of al-Qaeda's Hamburg cell – intentionally crashed two jet airliners into the Twin Towers of the World Trade Center in New York City. Both buildings collapsed within two hours from fire damage related to the crashes, destroying nearby buildings and damaging others. The hijackers crashed a third jet airliner into the Pentagon in Arlington County, Virginia, just outside Washington, D.C. The fourth jet airliner crashed into a field near Shanksville, Pennsylvania, after some of its passengers and flight crew attempted to retake control of the jet airliners, which the hijackers had redirected toward Washington D.C., to target the White House or the U.S. Capitol. None of the flights had any survivors. A total of 2,977 victims and the 19 hijackers perished in the attacks. Fifteen of the nineteen were citizens of Saudi Arabia, and the others were from the United Arab Emirates (2), Egypt, and Lebanon.
Fahd al-Quso
Al-Quso was wanted for his participation in the terrorist bombing of the USS "Cole" and other terror related activities, including partially funding the September 11, 2001 attacks on the World Trade Center buildings in New York City. Al-Quso was indicted by the Southern District Court of New York on May 15, 2003, for his role in the terrorist bombing of the USS "Cole" in Aden, Yemen, that resulted in the deaths of 17 people and wounded 40 others.
List of military operations in the war in Afghanistan (2001–present)
After the September 11, 2001, attacks, investigators rapidly accumulated evidence implicating Osama bin Laden. In a taped statement, bin Laden publicly acknowledged his and al-Qaeda's direct involvement in the 9-11 attacks. In an audiotape posted on a website that the U.S. claims is "frequently used by al-Qaeda", on May 21, 2006, bin Laden said he had personally directed the 19 hijackers.
International counter-terrorism activities of the CIA
On February 26, 1993, the World Trade Center was bombed. A group of the conspirators were arrested, convicted, and imprisoned. There has been no strong argument that al-Qaeda was involved, although there have been allegations, including by a former Director of Central Intelligence, that Iraq supported the operational cell. In a PBS interview in October 2001, former Clinton-era CIA Director James Woolsey argued a supposed link between Ramzi Youssef and the Iraqi intelligence services. He suggested the grand jury investigation turned up evidence pointing to Iraq that the Clinton Justice Department "brushed aside."
Ahmed Omar Saeed Sheikh
On 6 October 2001, a senior-level US government official, told CNN that US investigators had discovered Saeed (Sheik Syed), using the alias "Mustafa Muhammad Ahmad" had sent about $100,000 from the United Arab Emirates to Mohamed Atta. "Investigators said Atta then distributed the funds to conspirators in Florida in the weeks before the deadliest act of terrorism on U.S. soil that destroyed the World Trade Center, heavily damaged the Pentagon and left thousands dead. In addition, sources have said Atta sent thousands of dollars — believed to be excess funds from the operation — back to Syed in the United Arab Emirates in the days before September 11." CNN later confirmed this.
The Lone Gunmen
One retrospectively relevant aspect of this pilot episode is that the airliner has been hijacked (via remote control of the plane's autopilot) and, by the end, both Byers and his father have boarded the plane to try to stop the hijacking. Through the aid of the other Gunmen, they are able to regain control of the plane and just miss crashing into the World Trade Center with the airliner. This, of course, was before the actual September 11 attacks against the World Trade Center later that year.
Foreign policy of the Bill Clinton administration
On February 26, 1993, thirty-six days after Clinton took office, terrorists who the CIA would later reveal were working under the direction of Osama bin Laden detonated a timed car bomb in the parking garage below Tower One of the World Trade Center in New York City (see the World Trade Center bombing). Clinton responded by ordering his National Security Council, under the direction of Anthony Lake, and the FBI to find and punish those responsible. The FBI was able to quickly identify the vehicle used in the bomb from a remnant found in the rubble: a Ryder rental van, which had been reported stolen in Jersey City, New Jersey the day before. The truck was rented by Mohammed Salameh, whom the FBI immediately detained. Similar evidence led to the arrests of other plotters behind the attack, including Nidal Ayyad, Mahmoud Abouhalima, Ahmad Ajaj, and Ramzi Yousef—who was identified as the key player in the bombing. All men were tried and convicted for the bombing and other terrorists activities.
United Airlines Flight 175
United Airlines Flight 175 was a scheduled domestic passenger flight from Logan International Airport, in Boston, Massachusetts, to Los Angeles International Airport, in Los Angeles, California. On September 11, 2001, the Boeing 767-200 operating the route was hijacked by five al-Qaeda terrorists and was deliberately crashed into the South Tower of the World Trade Center in New York City, killing all 65 people aboard and an unconfirmed number in the building's impact zone. The attempt was part of the September 11 attacks.

Bailey died when the plane in which he was traveling, United Airlines Flight 175, was hijacked and deliberately crashed into the South Tower of the World Trade Center in New York City during the September 11 attacks. Bailey and amateur scout Mark Bavis were traveling from Boston to Los Angeles when the flight was hijacked. They had been in Manchester visiting the Los Angeles Kings' AHL affiliate, the Monarchs.
United Airlines Flight 93
After the hijackers took control of the plane, several passengers and flight attendants learned from phone calls that suicide attacks had already been made by hijacked airliners on the World Trade Center in New York City and the Pentagon in Arlington County, Virginia. Many of the passengers then attempted to regain control of the aircraft from the hijackers. During the struggle, the plane crashed into a field near a reclaimed strip mine in Stonycreek Township, near Indian Lake and Shanksville, about southeast of Pittsburgh and northwest of Washington, D.C. A few people witnessed the impact from the ground, and news agencies began reporting the event within an hour.
Satam al-Suqami
He arrived in the United States in April 2001. On September 11, 2001, Suqami boarded American Airlines Flight 11 and participated in the hijacking of the plane so that it could be crashed into the North Tower of the World Trade Center as part of the coordinated attacks.
Osama bin Laden
Meanwhile, on November 8, 1990, the FBI raided the New Jersey home of El Sayyid Nosair, an associate of al-Qaeda operative Ali Mohamed. They discovered copious evidence of terrorist plots, including plans to blow up New York City skyscrapers. This marked the earliest discovery of al-Qaeda terrorist plans outside of Muslim countries. Nosair was eventually convicted in connection to the 1993 World Trade Center bombing, and later admitted guilt for the murder of Rabbi Meir Kahane in New York City on November 5, 1990.
Planning of the September 11 attacks
"Investigators said Atta then distributed the funds to conspirators in Florida in the weeks before the deadliest acts of terrorism on U.S. soil that destroyed the World Trade Center, heavily damaged the Pentagon and left thousands dead [...] Syed also is described as a key figure in the funding operation of Al-Qaeda, the network headed by suspected terrorist mastermind Osama bin Laden."
World Trade Center (1973–2001)
On September 11, 2001, Islamist terrorists hijacked American Airlines Flight 11 and crashed it into the northern façade of the North Tower at 8:46:40 a.m., the aircraft striking between the 93rd and 99th floors. Seventeen minutes later, at 9:03:11 a.m., a second group crashed the similarly hijacked United Airlines Flight 175 into the southern façade of the South Tower, striking it between the 77th and 85th floors. The damage caused to the North Tower by Flight 11 destroyed any means of escape from above the impact zone, trapping 1,344 people. Flight 175 had a much more off-centered impact compared to Flight 11, and a single stairwell was left intact; however, only a few people managed to pass through it successfully before the tower collapsed. Although the South Tower was struck lower than the North Tower, thus affecting more floors, a smaller number, fewer than 700, were killed instantly or trapped.
David N. Kelley
David N. Kelley (born December 1, 1959) is an American attorney and a former United States Attorney and Deputy U.S. Attorney for the Southern District of New York (SDNY). He was also a co-chair of the United States Justice Department’s nationwide investigation into the September 11 attacks.
Kelley, who served as chief of the organized crime and terrorism unit in the U.S. Attorney's Office for the SDNY, is noted for leading the investigations of the 2000 millennium attack plots and the October 2000 attack on the USS "Cole" in Yemen, and for prosecuting Ramzi Yousef for his role in the 1993 World Trade Center bombing. He was named Special Assistant United States Attorney in the Eastern District of Virginia acting as co-lead prosecutor of John Walker Lindh. Kelley is also noted for obtaining convictions of WorldCom CEO Bernie Ebbers in his prosecution for accounting fraud and Martha Stewart in the ImClone stock trading case.
Kelley was raised in East Hampton, NY, and has lived in the New York metropolitan area for most of his life. He earned his undergraduate degree from The College of William & Mary and law degree in 1986 from New York Law School. Kelley was a policeman and a fireman while attending law school. After leaving the U.S. Attorney's office in 2005, Kelley joined Wall Street law firm Cahill Gordon & Reindel as a partner in its litigation and corporate investigations practice. He is currently a partner and co-leader in the White Collar and Securities Litigation practice group at Dechert.
Eleanor J. Hill
According to U.S. State Department cable of February 2010, released by WikiLeaks in 2011, the FBI has investigated another suspect, Mohammed al-Mansoori, who had associated with three Qatari citizens who had flown from Washington to London on the eve of the attacks, after allegedly surveying the World Trade Center and the White House. U.S. law enforcement officials said that the information 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, however, that the three Qatari citizens have never been questioned by the FBI. Eleanor Hill, the former staff director for 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 that 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 Sept. 10, 2001, on the same plane that was hijacked and piloted into the Pentagon on the following day, but did instead fly from Los Angeles to Qatar, via London. While the cable states that Mansoori would be currently under investigation, U.S. law enforcement officials said that was no active investigation of him or of the Qatari citizens mentioned in the cable.
New York City Fire Department
On September 11, 2001, American Airlines Flight 11 and United Airlines Flight 175 were hijacked by Islamic terrorists affiliated with Al Qaeda and flown into the World Trade Center's North and South Towers, respectively, causing massive damage to both towers during impact, and starting fires that caused the weakened 110-story skyscrapers to collapse within less than two hours.
1993 World Trade Center bombing
The 1993 World Trade Center bombing was a terrorist attack on the World Trade Center, carried out on February 26, 1993, when a truck bomb detonated below the North Tower of the World Trade Center in New York City. The urea nitrate–hydrogen gas enhanced device was intended to send the North Tower (Tower 1) crashing into the South Tower (Tower 2), bringing both towers down and killing tens of thousands of people. It failed to do so but killed six people and injured over a thousand.
Ziad Jarrah
On the morning of September 11, 2001, Jarrah, Saeed al-Ghamdi, Ahmed al-Nami and Ahmed al-Haznawi boarded United Airlines Flight 93 from Newark International Airport at gate A17 without incident, and sat in first-class seats near the cockpit. Before boarding, Ziad Jarrah called his girlfriend, Aysel Sengün, from a public telephone at the airport, repeating the words 'I love you' over and over. Due to the flight's delay, the plane took off at 8:41 am, five minutes before American Airlines Flight 11 crashed into the World Trade Center. The pilot and crew were notified of the first two hijackings that day, and were told to be on the alert. Within minutes, around 9:28 am, Flight 93 was hijacked as well. The 9/11 Commission stated that Jarrah was the pilot.
Oklahoma City bombing
Hundreds of news trucks and members of the press arrived at the site to cover the story. The press immediately noticed that the bombing took place on the second anniversary of the Waco incident. Many initial news stories hypothesized the attack had been undertaken by Islamic terrorists, such as those who had masterminded the 1993 World Trade Center bombing. Some responded to these reports by attacking Muslims and people of Arab descent.
Anthony Summers
Harnden said that there was "no real evidence" for Summers' and Swan's claims that the CIA negotiated with Osama bin Laden prior to those attacks, or of their attempt to recruit two of the hijackers as agents. While criticizing the authors for a lack of original research, failure to interview major figures within the Bush administration, and "habit of posing portentous questions without answering", he noted that their depiction of the "horrors inside the World Trade Center" and bravery of the Flight 93 passengers was "well written and moving".
Osama bin Laden
In the 2004 video, bin Laden abandoned his denials without retracting past statements. In it he said he had personally directed the nineteen hijackers. In the 18-minute tape, played on Al-Jazeera, four days before the American presidential election, bin Laden accused U.S. President George W. Bush of negligence in the hijacking of the planes on September 11. According to the tapes, bin Laden claimed he was inspired to destroy the World Trade Center after watching the destruction of towers in Lebanon by Israel during the 1982 Lebanon War.
World Trade Center (1973–2001)
On the morning of September 11, 2001, Al-Qaeda-affiliated hijackers flew two Boeing 767 jets into the North and South Towers within minutes of each other; two hours later, both towers collapsed. The attacks killed 2,606 people in and within the vicinity of the towers, as well as all 157 on board the two aircraft. Falling debris from the towers, combined with fires that the debris initiated in several surrounding buildings, led to the partial or complete collapse of all the buildings in the complex and caused catastrophic damage to ten other large structures in the surrounding area.
PENTTBOM
The investigators were quickly able to link the 19 men to the terrorist organization al Qaeda, by accessing their intelligence agency files. The "New York Times" reported on September 12 that: "Authorities said they had also identified accomplices in several cities who had helped plan and execute Tuesday's attacks. Officials said they knew who these people were and important biographical details about many of them. They prepared biographies of each identified member of the hijack teams, and began tracing the recent movements of the men." FBI agents in Florida investigating the hijackers quickly "descended on flight schools, neighborhoods and restaurants in pursuit of leads." At one flight school, "students said investigators were there within hours of Tuesday's attacks." "The Washington Post" later reported that "In the hours after Tuesday's bombings, investigators searched their files on [Satam] Al Suqami and [Ahmed] Alghamdi, noted the pair's ties to [Nabil] al-Marabh and launched a hunt for him."
Hamburg cell
The Hamburg cell () or Hamburg terror cell () was, according to U.S. and German intelligence agencies, a group of radical Islamists based in Hamburg, Germany that included students who eventually came to be key operatives in the 9/11 attacks. Important members included Mohamed Atta, who led the four hijacking teams in 2001 and piloted American Airlines Flight 11; Ramzi bin al-Shibh, who conspired with the other three members but was unable to enter the United States; Marwan al-Shehhi, who piloted United Airlines Flight 175; and Ziad Jarrah, who piloted United Airlines Flight 93 and failed to hit a target in Washington, D.C. (claimed by Khalid Sheikh Mohammed to have been the Capitol). Other members included Said Bahaji, Zakariya Essabar, Mounir el-Motassadeq, and Abdelghani Mzoudi.
1993 World Trade Center bombing
Claims of direct Iraqi involvement come from Dr. Laurie Mylroie of the American Enterprise Institute and former associate professor of the U.S. Naval War College, with the claims rejected by others. CNN reporter Peter Bergen has called her a "crackpot" who claimed that "Saddam was not only behind the '93 Trade Center attack, but also every anti-American terrorist incident of the past decade, from the bombings of U.S. embassies in Kenya and Tanzania to the leveling of the federal building in Oklahoma City bombing to September 11 itself." Daniel Benjamin, a senior fellow at the Center for Strategic and International Studies, writes: "The most knowledgeable analysts and investigators at the CIA and at the FBI believe that their work conclusively disproves Mylroie's claims." Dr. Robert Leiken of the Nixon Center comments on the lack of evidence in her work: "Laurie has discovered Saddam's hand in every major attack on US interests since the Persian Gulf War, including U.S. embassies in Kenya and Tanzania and even the federal building in Oklahoma City. These allegations have all been definitively refuted by the FBI, the National Transportation Safety Board (NTSB) and other investigatory bodies..."
