The Portland-to-Boston flight used by 9/11 hijackers Mohamed Atta and Abdulaziz Alomari arrives on time at Boston’s Logan Airport. [Der Spiegel, 2002] Atta and Alomari then cross a parking lot on their way to the departure terminal for Flight 11, and are observed asking for directions. The other three Flight 11 hijackers arrive at Logan Airport in a rented car around this same time (see (6:45 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 5]
7:45 a.m. September 11, 2001: Hijackers’ Bags Contain Airline Uniforms
Hijackers Mohamed Atta and Abdulaziz Alomari board Flight 11. Atta’s bags are not loaded onto the plane in time and will later be found by investigators. Investigators will discover airline uniforms in one of the bags. [Boston Globe, 9/18/2001] It will not be explained why Atta would have obtained these uniforms only to put them in his checked-in baggage, where he would be unable to access them.
8:46 a.m. September 11, 2001: Flight 11 Hits the North Tower of the World Trade Center
Flight 11 slams into the WTC North Tower (Building 1). Hijackers Mohamed Atta Waleed Alshehri, Wail Alshehri, Abdulaziz Alomari, and Satam Al Suqami presumably are killed instantly, and many more in the tower will die over the next few hours. Seismic records pinpoint the crash at 26 seconds after 8:46 a.m. [CNN, 9/12/2001; New York Times, 9/12/2001; 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; USA Today, 8/12/2002; Associated Press, 8/21/2002; Newsday, 9/10/2002] The NIST report states the crash time to be 8:46:30. [National Institute of Standards and Technology, 9/2005, pp. 19] The 9/11 Commission Report states the crash time to be 8:46:40. [9/11 Commission, 7/24/2004, pp. 7] Investigators believe the plane still has about 10,000 gallons of fuel (see 8:57 a.m. September 11, 2001). [New York Times, 5/26/2002] The plane strikes the 93rd through 99th floors in the 110-story building. No one above the crash line survives; approximately 1,360 people die. Below the crash line, approximately 72 die and more than 4,000 survive. Both towers are slightly less than half full at the time of the attack, with between 5,000 to 7,000 people in each tower. This number is lower than expected. Many office workers have not yet shown up to work, and tourists to the observation deck opening at 9:30 A.M. have yet to arrive. [USA Today, 12/20/2001; National Institute of Standards and Technology, 9/2005, pp. 20-22] The impact severs some columns on the north side of the North Tower. Each tower 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 weighs 283,600 lb and is traveling at an estimated speed of around 430 mph (see October 2002-October 2005), severs 35 of the building’s 236 perimeter columns and damages another two. The damage to the South Tower’s perimeter will be similar (see 9:03 a.m. September 11, 2001). [National Institute of Standards and Technology, 9/2005, pp. 5-9, 20, 22] The perimeter columns bear about half of the tower’s weight, so this damage reduces its ability to bear gravity loads by about 7.5 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 have damaged the core even after crashing through the exterior wall. According to the National Institute of Standards and Technology (NIST): “Moving at 500 mph, an engine broke any exterior column it hit. If the engine missed the floor slab, the majority of the engine core remained intact and had enough residual momentum to sever a core column upon direct impact.” [National Institute of Standards and Technology, 9/2005, pp. 107] According to NIST’s base case computer model, three of the core columns are severed and another ten suffer some damage. [National Institute of Standards & Technology, 9/2005, pp. 189 
] If this is accurate, it means that the impact damage to the core reduces the Tower’s strength by another approximately 7.5 percent, meaning that the building loses about 15 percent of its strength in total. This damage will be cited after 9/11 by NIST and others researchers as an event contributing to the building’s collapse (see October 23, 2002 and October 19, 2004). In addition, some of the fireproofing on the steel columns and trusses may be dislodged. The original fireproofing on the fire floors was mostly Blazeshield DC/F, but some of the fireproofing on the flooring has recently been upgraded to Blazeshield II, which is about 20 percent denser and 20 percent more adhesive. [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 NIST will estimate the damage to it using a computer model. Its severe case model (see (October 2002-October 2005)) will predict that 43 of the 47 core columns are stripped of their fireproofing on one or more floors and that fireproofing is stripped from trusses covering 60,000 ft2 of floor area, the equivalent of about one and a half 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. 23] According to NIST, more fireproofing is stripped from the South Tower (see 9:03 a.m. September 11, 2001).
Shortly After September 11, 2001: Three More 9/11 Hijacker Passports Recovered
According to the 9/11 Commission, the passports of two hijackers are discovered in the wreckage of Flight 93. One passport, belonging to Saeed Alghamdi, is damaged but still readable. The other passport, belonging to Ziad Jarrah, is burned most of the way through, but part of his photograph is still visible. In addition, the passport of hijacker Abdulaziz Alomari is recovered because apparently it was put in Mohamed Atta’s luggage and the luggage did not get put on the flight Alomari and Atta were hijacking before it took off (see September 11-13, 2001). The recovery of these passports will not be made public at the time and will only be mentioned in passing in 2004 by the 9/11 Commission. A fourth passport, that of Satam Al Suqami, was also recovered on a street near the WTC (see After 8:46 a.m. September 11, 2001). That did become immediate news and caused skepticism by many who wondered how a paper document could survive such a crash (see After 8:46 a.m. September 11, 2001). [9/11 Commission, 1/26/2004]
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 16-23, 2001: Media Displays Confusion over Hijacker Identities
Reports appear in many newspapers suggesting that some of the people the US initially says were 9/11 hijackers are actually still alive and that the actual hijackers may have used stolen identities: No media outlet has claimed that Hamza Alghamdi is still alive, but his family says the FBI photo “has no resemblance to him at all.” [Arab News, 9/22/2001; Washington Post, 9/25/2001] CNN shows a picture of a Saudi pilot called Saeed Alghamdi and claims it is the hijacker of the same name. However, the pilot is alive and working in Tunisia. The FBI listed the hijacker’s possible residence as Delray Beach, Florida, where the pilot trained in 1998, 1999, and 2000, which may be why CNN uses a photograph of the wrong person. The pilot returns to Saudi Arabia to avoid problems and CNN apologises for the error. [Federal Bureau of Investigation, 9/14/2001; Arab News, 9/18/2001; Los Angeles Times, 9/21/2001; Daily Telegraph, 9/23/2001; BBC, 9/23/2001] A man named Salem Alhazmi claims he is the alleged hijacker of the same name, but he works in a petrochemical plant and had his passport stolen three years ago in Cairo. He says a picture being used in the media is of him. However, he is a different age to the hijacker, 26 not 21, has a different middle name, Ibrahim not Mohamed, and the photos appear to be of different people. In addition, the FBI does not release official pictures of the hijackers until a week after he makes this claim. The father of the other Salem Alhazmi says his son is missing, as is Salem’s brother and fellow hijacker Nawaf Alhazmi. [Washington Post, 9/20/2001; Los Angeles Times, 9/21/2001; Guardian, 9/21/2001; Daily Telegraph, 9/23/2001; Federal Bureau of Investigation, 9/27/2001; Saudi Gazette, 9/29/2002; 9/11 Commission, 8/21/2004, pp. 191 ; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] A man named Ahmed Alnami is alive and working as an administrative supervisor with Saudi Arabian Airlines in Riyadh, Saudi Arabia. [Los Angeles Times, 9/21/2001] He has never lost his passport and finds it “very worrying” that his identity appears to have been stolen. [Daily Telegraph, 9/23/2001] However, there is another Ahmed Alnami who is 10 years younger and appears to be dead, according to his father. [ABC News, 3/15/2002] Ahmed Alnami’s family says his FBI picture is correct. [Washington Post, 9/25/2001] A man called Abdulrahman Alomari is alive and works as a pilot for Saudi Arabian Airlines. [New York Times, 9/16/2001; Independent, 9/17/2001; BBC, 9/23/2001] He was a neighbour of Adnan Bukhari and Amer Kamfar, who were both wrongly suspected of involvement in the 9/11 attacks at the start of the investigation. He moved out of his home in Vero Beach, Florida, shortly before the attacks. [CNN, 9/14/2001] A man called Abdulaziz Alomari is an engineer with Saudi Telecoms. [BBC, 9/23/2001] He claims that his passport was stolen in 1995 while he was living in Denver, Colorado. [Los Angeles Times, 9/21/2001] He says: “They gave my name and my date of birth, but I am not a suicide bomber. I am here. I am alive.” [London Times, 9/20/2001; Daily Telegraph, 9/23/2001] The FBI initially gave two possible birthdates for Abdulaziz Alomari. One is apparently that of the engineer, the other that of the alleged hijacker. [Federal Bureau of Investigation, 9/14/2001; New Yorker, 5/27/2002; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] The Saudi government has claimed that Mohand Alshehri is alive and that he was not in the US on 9/11, but no more details are known. [Associated Press, 9/29/2001] The brothers Waleed M. Alshehri and Wail Alshehri are alive. Their father is a diplomat who has been stationed in the US and Mumbai (Bombay), India. A Saudi spokesman says: “This is a respectable family. I know his sons and they’re both alive.” [Arab News, 9/19/2001; Los Angeles Times, 9/21/2001] There is a second pair of Saudi brothers named Wail and Waleed M. Alshehri who may have been the real hijackers. Their father says they have been missing since December 2000. [Arab News, 9/17/2001; ABC News, 3/15/2002] The still-living Waleed M. Alshehri is a pilot with Saudi Airlines, studying in Morocco. [Los Angeles Times, 9/21/2001; Associated Press, 9/22/2001] He acknowledges that he attended flight training school at Dayton Beach in the United States. [BBC, 9/23/2001; Daily Trust (Abuja), 9/24/2001] He was interviewed by US officials in Morocco and cleared of all charges against him (though apparently the FBI is still using his picture). [Embry Riddle Aeronautical University, 9/21/2001] The still-living Waleed Alshehri is also apparently a pilot. [Los Angeles Times, 9/21/2001] He claims he saw his picture on CNN and recognized it from when he studied flying in Florida. But he also says he has no brother named Wail. [As-Sharq Al-Awsat (London), 9/22/2001] Mohamed Atta’s father says he spoke to his son on the phone on September 12, 2001. [New York Times, 9/19/2001; Chicago Tribune, 9/20/2001] On September 19, the Federal Deposit Insurance Corporation distributes a “special alert” to its member banks asking for information about the attackers. The list includes “Al-Midhar, Khalid. Alive.” The Justice Department later calls this a “typo.” [Associated Press, 9/20/2001; Cox News Service, 10/21/2001] The BBC says, “There are suggestions that another suspect, Khalid Almihdhar, may also be alive.” [BBC, 9/23/2001] The Guardian says Almihdhar is believed to be alive, but investigators are looking into three possibilities. Either his name was stolen for a hijacker alias, or he allowed his name to be used so that US officials would think he died, or he died in the crash. [Guardian, 9/21/2001] Majed Moqed was last seen by a friend in Saudi Arabia in 2000. This friend claims the FBI picture does not look like Moqed. [Arab News, 9/22/2001]
The Official Account Evolves – The Saudi government insists that five of the Saudis mentioned as 9/11 hijackers are still alive. [New York Times, 9/21/2001] On September 20, FBI Director Robert Mueller says: “We have several others that are still in question. The investigation is ongoing, and I am not certain as to several of the others.” [Newsday, 9/21/2001] On September 27, after all of the revelations mentioned above are reported in the media, Mueller will state, “We are fairly certain of a number of them.” [South Florida Sun-Sentinel, 9/28/2001] On September 20, the London Times reports, “Five of the hijackers were using stolen identities, and investigators are studying the possibility that the entire suicide squad consisted of impostors.” [London Times, 9/20/2001] The mainstream media briefly doubts some of the hijackers’ identities. For instance, a story in The Observer on September 23 puts the names of hijackers like Saeed Alghamdi in quotation marks. [Observer, 9/23/2001] However, the story will die down, and it will hardly be noticed when Mueller states on November 2, 2001: “As I have indicated before, one of the initial responsibilities of that investigation was to determine who the hijackers were. We at this point definitely know the 19 hijackers who were responsible for that catastrophe.” [Office of the Press Secretary, 11/2/2001] A law enforcement source, speaking on condition of anonymity, will confirm that the hijackers’ names released in late September, on the 28th, are the true identities of all 19 hijackers. The Associated Press story quoting him will add that “the names were those listed on the planes’ passenger manifests and investigators were certain that those were the names the hijackers used when they entered the United States.” But the Saudi Institute, an independent human rights watchdog group that researches the hijackers’ identities, will maintain that Abdulaziz Alomari used someone else’s passport. [Associated Press, 11/3/2001; Associated Press, 11/3/2002] In 2003, FBI spokesman Bill Carter will say: “There has been no change in thought about the identities of those who boarded those planes. It’s like saying my name is John Smith. There are a lot of people with the name of John Smith, but they’re not the same person.” When asked about Mueller’s comments, Carter will say, “He might have told Congress [about the identity theft], but we have done a thorough investigation and we are confident.” Carter will also comment that the bureau identified the hijackers “[t]hrough extensive investigation,” and say, “We checked the flight manifests, their whereabouts in this country, and we interviewed witnesses who identified the hijackers.” [Insight, 6/24/2003] The 9/11 Commission will later endorse the hijackers’ names published by the FBI around this time. [9/11 Commission, 7/24/2004]
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]
May 16, 2002: Pakistan Raid Shows Son of Saudi Official Is Associated with 9/11 Hijackers
A CD-ROM containing a picture of a young Saudi man named Saud al-Rashid is seized in an al-Qaeda safe house in Karachi, Pakistan. The CD also contains the pictures of three 9/11 hijackers, Nawaf Alhazmi, Khalid Almihdhar, and Abdulaziz Alomari, placed in the same folder with the picture of al-Rashid. The pictures are all passport photos or pages of entry and exit stamps from the same passports. All the computer files of the pictures were saved in May 2001. A senior US official says that investigators “were able to take this piece of information and it showed clear signals or lines that [al-Rashid] was connected to 9/11.” Media reports in 2002 say that the raid takes place on August 15, but an FBI report made public years later will show the raid took place on May 16 but the importance of the CD-ROM’s contents was not discovered until August 15. [Associated Press, 8/21/2002; 9/11 Commission, 7/24/2004, pp. 526; Federal Bureau of Investigation, 2010]
Al-Rashid Escapes Dragnet – On August 21, six days after the files on the CD-ROM are discovered, the US will issue a worldwide dragnet to find al-Rashid. [Associated Press, 8/21/2002] But they are unable to catch him because a few days later, he flees from Egypt to Saudi Arabia and turns himself in to the Saudi authorities. The Saudis apparently will not try him for any crime or allow the FBI to interview him. [CNN, 8/26/2002; CNN, 8/31/2002]
Al-Rashid’s Background – Al-Rashid was in Afghanistan in 2000 and 2001, where he met 9/11 hijacker Ahmed Alhaznawi “once or twice” in a guest house. [New York Times, 7/29/2003; 9/11 Commission, 7/24/2004, pp. 526] Although detainees identify him as a candidate 9/11 hijacker, he claims not to have met Osama bin Laden or Khalid Shaikh Mohammed (KSM), or even to have heard of al-Qaeda. Under interrogation, KSM will say al-Rashid was headstrong and immature and dropped out of the plot after returning to Saudi Arabia for a visa, either due to second thoughts or the influence of his family. However, doubts will be raised about the reliability of KSM’s statements under interrogation (see August 6, 2007). [9/11 Commission, 7/24/2004, pp. 526] Intriguingly, al-Rashid’s father is Hamid al-Rashid, a Saudi government official who paid a salary to Omar al-Bayoumi, an associate of both Almihdhar and Alhazmi who is later suspected of being a Saudi agent. [New York Times, 7/29/2003]
Passport Clue – Also intriguingly, the pictures from Saeed Alghamdi’s and Khalid Almihdhar’s passports show the passports were issued at “Holy Capital.” This may be an indicator placed by the Saudi government to show that the passport holders are radicals. [Federal Bureau of Investigation, 2010]
Other Evidence? – Florida FBI agent Tom Yowell will later mention to the 9/11 Commission that he remembers some other 9/11-related evidence captured in a May 2002 Karachi raid, including mention of the address of a Virginia post office box (see February 19-20, 2001 and April 3-4, 2001 and around) and videos of the 9/11 hijackers. But which hijackers were videotaped, and where and when, is not mentioned. [9/11 Commission, 12/4/2003 ]
September 8-11, 2002: Interview with Al-Qaeda Leaders KSM and Bin Al-Shibh Is Broadcast
Details of an Al Jazeera interview with al-Qaeda leaders Khalid Shaikh Mohammed (KSM) and Ramzi bin al-Shibh (see April, June, or August 2002) are widely publicized starting on September 8, 2002. [London Times, 9/8/2002; Australian, 9/9/2002; Guardian, 9/9/2002] But there are numerous doubts about this interview, since there is no video footage and only audio footage from bin al-Shibh. It has further been suggested that the broadcast of bin al-Shibh’s voice in the interview helps in his arrest (see September 11, 2002). [Observer, 9/15/2002; CBS News, 10/9/2002] Bin al-Shibh’s voice is first broadcast on September 9, 2002, as part of uncredited narration on another documentary released that day (see September 9, 2002). His voice is only publicly identified as his on the morning of September 11, 2002, just hours before bin al-Shibh is said to be arrested. [Fouda and Fielding, 2003, pp. 159] Al Jazeera also broadcasts footage of hijacker Abdulaziz Alomari speaking against the US filmed in Afghanistan in early 2001 (see September 9, 2002) and other footage of some other hijackers (see September 9, 2002). [Financial Times, 9/11/2002]
September 9, 2002: Video of 9/11 Hijacker Cursing US and Praising Bin Laden Is Released
A martyr video of 9/11 hijacker Abdulaziz Alomari is broadcast on the Al Jazeera satellite network. In it, Alomari gives a speech that he calls his last will and testament, and says: “I am writing this with my full conscience and I am writing this in expectation of the end, which is near. An end that is really a beginning.” He implores the US to “take your fat hands off the land of Arabs.… We will get you. We will humiliate you. We will never stop following you.… God praise everybody who trained and helped me, namely the leader Sheikh Osama bin Laden. May God bless him. May God accept our deeds.” It is believed that Alomari recorded the video around March 2001, the same time most of the other 9/11 hijackers recorded similar videos (see March 2001), and the background of a burning Pentagon was added digitally after 9/11. [CNN, 9/9/2002; Washington Post, 9/11/2002] Alomari’s speech is part of an hour-long al-Qaeda video broadcast on Al Jazeera (see September 9, 2002).
