At least five tickets are one way only. [Los Angeles Times, 9/18/2001] There are numerous connections between the hijackers booked on the four flights by this point: Hijackers on different 9/11 flights arrived in the US on the same plane. For example, Salem Alhazmi (Flight 77) arrived with Abdulaziz Alomari (Flight 11), and Fayez Ahmed Banihammad (Flight 175) arrived with Saeed Alghamdi (Flight 93) (see April 23-June 29, 2001); Two of the pilots, Mohamed Atta and Marwan Alshehhi, train and live together, and have a joint bank account (see (Mid-July 2000 – Early January 2001), July 6-December 19, 2000, and June 28-July 7, 2000); Hijackers from different planes open bank accounts together (see May 1-July 18, 2001 and June 27-August 23, 2001); and The hijackers obtain identity documents together (see April 12-September 7, 2001 and August 1-2, 2001).
Six hijackers also provide the same phone number and three use the same address. [Miami Herald, 9/22/2001]
6:20 a.m.-7:27 a.m. September 11, 2001: Flight 175 Hijackers Check In at Airport and Board Plane; None Selected for Additional Security Scrutiny
All five Flight 175 hijackers reportedly check in at Boston’s Logan Airport, pass through a security checkpoint, and board their plane during this period. The five hijackers are Marwan Alshehhi, Fayez Ahmed Banihammad, Hamza Alghamdi, Ahmed Alghamdi, and Mohand Alshehri. [9/11 Commission, 8/26/2004, pp. 89] The FAA has a program in place called CAPPS, which selects passengers for more thorough security screening based on suspicious behavior such as buying a one-way ticket or paying with cash (see (6:20 a.m.-7:48 a.m.) September 11, 2001). Although reports claim that between two and five of the Flight 175 hijackers have one-way tickets, none are selected by CAPPS. [WorldNetDaily, 4/24/2002; US Congress, 9/26/2002; US Congress, 9/26/2002; Washington Post, 1/28/2004; 9/11 Commission, 8/26/2004, pp. 18] Two of them have problems answering security questions at the ticket counter (see (6:20 a.m.-6:53 a.m.) September 11, 2001). At the security checkpoint, all five would pass through a walk-through metal detector, and an X-ray machine would screen their carry-on luggage. But Logan Airport has no video surveillance of its checkpoints (see 1991-2000), so there is no documentary evidence of exactly when they go through, or how they are processed. Jennifer Gore, the young supervisor overseeing the checkpoint, is later unable to recall seeing any of them. The Globe and Mail will explain, “[S]he was trained to look for metal bits in bags and in clothes, not people.” [Globe and Mail, 9/7/2002; 9/11 Commission, 7/24/2004, pp. 2; 9/11 Commission, 8/26/2004, pp. 18]
6:20 a.m.-6:53 a.m. September 11, 2001: Two Flight 175 Hijackers Check in at United Airlines Ticket Counter; Uncertainty Over Their Identities
Two of the Flight 175 hijackers approach a customer service representative at the United Airlines ticket counter at Boston’s Logan Airport. The two appear unaccustomed to traveling. One tells the representative, Gail Jawahir, that he needs a ticket, though upon examining his documents she finds he already has one. Both men have problems answering standard security questions, which Jawahir has to repeat very slowly until they give the routine, reassuring answers. There is conflicting evidence over their identities. Jawahir will place her encounter with the men at “shortly before 7 a.m.” Shown photos of the alleged hijackers after 9/11, she will indicate that one of the two she encountered resembled Mohand Alshehri, suggesting the two were Alshehri and Fayez Ahmed Banihammad, who checked in at 6:53 a.m. Yet she recalls the two having the same last name and having assigned seats on Row 9 of the plane, suggesting they were Ahmed and Hamza Alghamdi, who checked in at 6:20 a.m. [9/11 Commission, 7/24/2004, pp. 2, 451; 9/11 Commission, 8/26/2004, pp. 17-18, 89]
9:03 a.m. September 11, 2001: Flight 175 Crashes into WTC South Tower; Millions Watch Live on Television
Flight 175 hits the South Tower of the World Trade Center (Tower Two). Seismic records pinpoint the time at six seconds before 9:03 a.m. (rounded to 9:03 a.m.). Hijackers Marwan Alshehhi, Fayez Ahmed Banihammad, Mohand Alshehri, Hamza Alghamdi, and Ahmed Alghamdi presumably are killed instantly, and many more in the tower will die over the next few hours. [New York Times, 9/12/2001; CNN, 9/12/2001; CNN, 9/17/2001; North American Aerospace Defense Command, 9/18/2001; USA Today, 12/20/2001; Federal Emergency Management Agency, 5/1/2002, pp. 1-10; New York Times, 5/26/2002; Associated Press, 8/21/2002; USA Today, 9/2/2002] According to the NIST report, the crash time is 9:02:59. [National Institute of Standards and Technology, 9/2005, pp. 38] According to the 9/11 Commission Report, the crash time is 9:03:11. [9/11 Commission, 7/24/2004, pp. 8] Millions watch the crash live on television. The plane strikes the 77th through 85th floors in the 110-story building. Approximately 100 people are killed or injured in the initial impact; 600 people in the tower eventually die. The death toll is far lower than in the North Tower because about two-thirds of the South Tower’s occupants have evacuated the building in the 17 minutes since the first tower was struck. [USA Today, 12/20/2001; National Institute of Standards and Technology, 9/2005, pp. 5-9, 41] The combined death toll from the two towers is estimated at 2,819, not including the hijackers. [Associated Press, 8/21/2002] The impact severs some columns on the south side of the South Tower. Each of the Twin Towers is designed as a “tube-in-tube” structure and the steel columns which support its weight are arranged around the perimeter and in the core. The plane, which is traveling at an estimated speed of around 500 mph (see October 2002-October 2005), severs 33 of the building’s 236 perimeter columns and damages another one. [National Institute of Standards and Technology, 9/2005, pp. 39] The perimeter columns bear about half of the tower’s weight, so the damage to them reduces the tower’s ability to bear gravity loads by about 7.1 percent. [National Institute of Standards and Technology, 9/2005, pp. 6] The actual damage to the 47 core columns is not known, as there are no photographs or videos of it, but there will be much speculation about this after 9/11. It will be suggested that some parts of the aircraft may be able to damage the core even after crashing through the exterior wall (see 8:46 a.m. September 11, 2001). [National Institute of Standards and Technology, 9/2005, pp. 107] According to NIST’s base case model, five of the core columns are severed and another five suffer some damage. [National Institute of Standards & Technology, 9/2005, pp. 235 ] This may reduce the tower’s ability to bear loads by a further approximately 8 percent, meaning that the aircraft impact accounted for a loss of about 15 percent of the building’s strength. This damage will be cited as an event contributing to the building’s collapse after 9/11 (see October 23, 2002 and October 19, 2004). NIST’s base case estimate of damage to the North Tower’s core will be similar, even though the aircraft impact there was dissimilar (see 8:46 a.m. September 11, 2001). Flight 11 hit the North Tower’s core head on, whereas Flight 175 only hits the corner of the South Tower’s core. [National Institute of Standards and Technology, 9/2005, pp. 20-23, 38-41] In addition, some of the fireproofing on the steel columns and trusses may be dislodged (see 8:46 a.m. September 11, 2001). [National Institute of Standards & Technology, 9/2005, pp. xxxvi, 83 ] Photographs and videos of the towers will not show the state of fireproofing inside the buildings, but the National Institute of Standards and Technology (NIST) will try to estimate the damage to fireproofing using a series of computer models. Its severe case model (see (October 2002-October 2005)) will predict that 39 of the 47 core columns are stripped of their fireproofing on one or more floors and that fireproofing is stripped from trusses covering 80,000 ft2 of floor area, the equivalent of about two floors. NIST will say that the loss of fireproofing is a major cause of the collapse (see April 5, 2005), but only performs 15 tests on fireproofing samples (see October 26, 2005). [National Institute of Standards and Technology, 9/2005, pp. 41] According to NIST, less fireproofing is stripped from the North Tower (see 8:46 a.m. September 11, 2001).
September 11, 2001: Existing Files on Hijackers Enables Investigation to Start Within Hours of Attacks
One day after 9/11, the New York Times will report that 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.” [New York Times, 9/13/2001] Also on September 12, the Times will report, “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.” [New York Times, 9/13/2001] In September 2002, 9/11 victim’s relative Kristen Breitweiser, testifying before the 9/11 Congressional Inquiry, will cite these news reports and will ask, “How did the FBI know exactly where to go only a few hours after the attacks? How did they know which neighborhoods, which flight schools and which restaurants to investigate so soon in the case?… How are complete biographies of the terrorists, and their accomplices, created in such short time? Did our intelligence agencies already have open files on these men? Were they already investigating them? Could the attacks of September 11th been prevented?” [US Congress, 9/18/2002] In at least some cases, it appears that US intelligence did quickly access existing files on the hijackers. The Washington Post reports, “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.” A top Customs official claims that by checking flight manifests and comparing them with other information such as watch lists, he is able to determine the names of all 19 hijackers by 11:00 a.m.(see (11:00 a.m.) September 11, 2001). [Washington Post, 9/21/2001]
Afternoon September 11, 2001: Several Hijackers Have Tickets for Afternoon 9/11 Flights
Several of the hijackers have tickets to continue from the destinations of their 9/11 flights. However, they do not take the flights, as all air traffic has been grounded in the US (see (9:26 a.m.) September 11, 2001), and they are presumed to have died in the 9/11 attacks. Flight 77 hijackers Nawaf and Salem Alhazmi, and Flight 175 hijackers Fayez Ahmed Banihammad, Mohand Alshehri, and Hamza Alghamdi are to fly from Los Angeles to San Francisco. Flight 93 hijacker Ahmed Alhaznawi is to continue from San Francisco to San Diego, whereas Ziad Jarrah is to continue to Las Vegas. Alghamdi also has tickets for flights later in September (see September 20-29, 2001). [Federal Bureau of Investigation, 10/2001, pp. 233, 238, 242 246, 288 ]
September 15-17, 2001: Media Reports Suggest Some Hijackers Received US Military Training
A series of articles suggests that at least six of the 9/11 hijackers trained at US military bases. [New York Times, 9/15/2001; Newsweek, 9/15/2001; Washington Post, 9/16/2001] Three of the alleged hijackers—Ahmed Alnami, Ahmed Alghamdi, and Saeed Alghamdi—are revealed as having listed the Naval Air Station in Pensacola, Florida, as their permanent address on their driver’s licenses and car registrations, between 1996 and 1998. According to military records, the three used 10 Radford Boulevard as their address. This is a base roadway where residences for foreign-military flight trainees are located. Hamza Alghamdi was also connected to the Pensacola base (see 1996-August 2000). [Newsweek, 9/15/2001; Washington Post, 9/16/2001; Pensacola News Journal, 9/17/2001] Air Force spokesman Colonel Ken McClellan states that Saeed Alghamdi also attended the Defense Language Institute in Monterey, California. The Washington Post and Time magazine say he graduated from the Defense Language Institute at Lackland Air Force Base in San Antonio, Texas. (It is unclear whether Alghamdi therefore attended both Defense Language Institutes, or if this is simply a reporting error.) [Washington Post, 9/16/2001; Gannett News Service, 9/17/2001; Time, 9/24/2001] According to a high-ranking Pentagon official, another alleged hijacker was a former Saudi Air Force pilot who may have received training in strategy and tactics at the Air War College at Maxwell Air Force Base in Montgomery, Alabama. [Los Angeles Times, 9/15/2001; Newsweek, 9/15/2001] A further hijacker—also said to be a former Saudi Air Force pilot—may have been given language instruction at Lackland Air Force Base. [Los Angeles Times, 9/15/2001; Newsweek, 9/15/2001] A man called Abdulaziz Alomari (the same name as one of the suspected Flight 11 hijackers) attended Brooks Air Force Base Aerospace Medical School in San Antonio, Texas. [Washington Post, 9/16/2001; Gannett News Service, 9/17/2001] Ken McClellan says a man with the name Mohamed Atta once attended the US International Officers School at Maxwell Air Force Base, Alabama (see 1998). [Washington Post, 9/16/2001; Gannett News Service, 9/17/2001]
According to Newsweek, it is not unusual for foreign nationals to train at US military facilities. A former Navy pilot tells the magazine that during his years at the Naval Air Station in Pensacola, “we always, always, always trained other countries’ pilots. When I was there two decades ago, it was Iranians. The shah was in power. Whoever the country du jour is, that’s whose pilots we train.” Newsweek adds that the “US has a long-standing agreement with Saudi Arabia… to train pilots for its National Guard.” [Newsweek, 9/15/2001] The media stops looking into the hijackers’ possible US military connections after the Air Force makes a less than definitive statement, saying, “Some of the FBI suspects had names similar to those used by foreign alumni of US military courses. However discrepancies in their biographical data, such as birth dates 20 years off, indicate we are probably not talking about the same people.” [Washington Post, 9/16/2001]
September 27, 2001: Photos of All 19 9/11 Hijackers Released for First Time
The photos of all 19 of the 9/11 hijackers are released by the FBI for the first time. Some photos have been released by the media already; for instance, a photo of Mohammed Atta became very well known a couple of days after the 9/11 attacks. But this is the first time all of the hijackers are seen. The FBI also gives out some details about the hijackers, but these details are scanty. For instance, the only detail mentioned for Ahmed Alhaznawi is, “Possibly lived in Delray Beach, Florida.” Interestingly, one detail mentioned for Khalid Almihdhar is, “May be an assumed name; there are reports he is still alive.” It also is noted that the identities of Waleed Alshehri, Wail Alshehri, Abdulaziz Alomari, Mohand Alshehri, Salem Alhazmi, and Saeed Alghamdi are in dispute, and some of the information about them may be confused with other people with similar names. [CNN, 9/27/2001]
September 10-11, 2002: Al-Qaeda Safe Houses Shut Down in Karachi, Pakistan
A suspected al-Qaeda operative named Ahmed Ghulam Rabbani is arrested in a safe house in Karachi, Pakistan, on September 10, 2002. He is a Saudi who later became a Pakistani citizen. Starting in 2000, he began running an al-Qaeda safe house in Karachi. He will be held in Pakistani custody until he is transferred to a US prison in Afghanistan in May 2004. He will be sent to the US-run Guantanamo prison in Cuba in September 2004. His driver, Muhammad Madni, is arrested too, and Madni reportedly quickly reveals the location of other safe houses in Karachi. [US Department of Defense, 5/26/2008] Abdul Rahim Ghulam Rabbani, Ahmed Ghulam Rabbani’s brother, is arrested at one of the safe houses this same day. According to Abdul Rahim’s 2008 Guantanamo file, he is an important al-Qaeda figure because he began running up to six Karachi safe houses, on behalf of 9/11 mastermind Khalid Shaikh Mohammed (KSM), from early 2000 until his capture. According to his file, many important al-Qaeda leaders stayed at his safe houses and interacted with him or his brother while they were passing through Karachi, including: Saif al-Adel, Abd al-Rahim al-Nashiri, Khallad bin Attash, Saad bin Laden, KSM, Ali Abdul Aziz Ali, Musaad Aruchi, and Hassan Ghul (who is said to be his brother-in-law). Furthermore, 17 of the 19 9/11 hijackers stayed at his safe houses while coming or going through Pakistan, including Mohamed Atta, Marwan Alshehhi, Hani Hanjour, and Ahmed Alghamdi (the others are not mentioned in his Guantanamo file by name). Abdul Rahim does not admit knowing their mission, but says he picked them up at airports, kept them at safe houses, and transported some of them to their next destinations. He apparently is working on a plot to bomb Karachi hotels used by Westerners, but it is scuttled by the arrests. He is held by Pakistan for two months, then he will be handed to US forces and held in various prisons in Afghanistan until September 2004, when he is transferred to Guantanamo. [US Department of Defense, 6/9/2008] The next day, these other safe houses are raided by the ISI (Pakistan’s intelligence agency). 9/11 hijacker associate Ramzi bin al-Shibh is arrested at one of the safe houses (see September 11, 2002). However, in contrast to the claim that the arrest of Ahmed Ghulam Rabbani led to the arrest of bin al-Shibh and others, there is a claim that an Al Jazeera reporter, Yosri Fouda, interviewed bin al-Shibh and KSM in a Karachi safe house in the middle of 2002 (see April, June, or August 2002), then told the emir of Qatar, Sheikh Hamad bin Khalifa al-Thani, where the interview took place, and the emir told the CIA. The CIA then began intensely monitoring Karachi for safe houses, which finally led to these raids (see June 14, 2002 and Shortly After). Hassan Ali bin Attash, brother of al-Qaeda leader Khallad bin Attash, is arrested at the same safe house as bin al-Shibh. Hassan will later be named by many other Guantanamo prisoners as an al-Qaeda operative, but not nearly as important a one as his brother. He will later say that he was held by the Pakistani government for a few days, then taken to Kabul, Afghanistan, by US forces for a few days, and then sent to Jordan and kept in Jordanian custody for over a year. He will be transferred to Guantanamo in January 2004, and where he subsequently remains. [US Department of Defense, 6/25/2008] One other suspected al-Qaeda operative is arrested at the safe house with bin al-Shibh and bin Attash (located on Tariq Road). The three of them allegedly hold knives to their throats and threaten to kill themselves rather than be captured. But they are overwhelmed after a four-hour stand-off. [US Department of Defense, 12/8/2006] At another safe house, there is a gun battle when it is raided. Two suspected al-Qaeda operatives are killed. One of those killed, Hamza al-Zubayr, is considered an al-Qaeda leader and the leader of the group in the house. The remaining six are arrested. All six will later be transferred to Guantanamo. [US Department of Defense, 6/25/2008] All of the above is based on Guantanamo files leaked to the public in 2011 by the non-profit whistleblower group WikiLeaks. There are many doubts about the reliability of the information in the files (see April 24, 2011).
October 21, 2002: 13 Hijackers Were Never Interviewed by US Consular Officials
The General Accounting Office, the nonpartisan investigative arm of Congress, releases a report asserting that at least 13 of the 19 9/11 hijackers were never interviewed by US consular officials before being granted visas to enter the US. This contradicts previous assurances from the State Department that 12 of the hijackers had been interviewed. It also found that, for 15 hijackers whose applications could be found, none had filled in the documents properly. Records for four other hijackers (the four non-Saudis, i.e., Ziad Jarrah, Mohamed Atta, Fayez Ahmed Banihammad, and Marwan Al Shehhi) could not be checked because they were accidentally destroyed. [National Review Online, 10/21/2002; United States General Accounting Office, 10/21/2002 ; Washington Post, 10/22/2002] The State Department maintains that visa procedures were properly followed. In December 2002, Senators Jon Kyl (R-AZ) and Pat Roberts (R-KS) state in a chapter of the 9/11 Congressional Inquiry that “if State Department personnel had merely followed the law and not granted non-immigrant visas to 15 of the 19 hijackers in Saudi Arabia… 9/11 would not have happened.” [Associated Press, 12/19/2002; US Congress, 7/24/2003, pp. pp. 653-673 ]
