A Saudi named Mohamed al-Khatani is stopped at the Orlando, Florida, airport and denied entry to the US. Jose Melendez-Perez, the customs official who stops him, later says he was suspicious of al-Khatani because he had arrived with no return ticket, no hotel reservations, spoke little English, behaved menacingly, and offered conflicting information on the purpose of his travel. At one point, al-Khatani said that someone was waiting for him elsewhere at the airport. After 9/11, surveillance cameras show that Mohamed Atta was at the Orlando airport that day. 9/11 Commissioner Richard Ben-Veniste says: “It is extremely possible and perhaps probable that [al-Khatani] was to be the 20th hijacker.” Al-Khatani boards a return flight to Saudi Arabia. He is later captured in Afghanistan and sent to a US military prison at Guantanamo Bay, Cuba (see December 2001). Melendez-Perez says that before 9/11, customs officials were discouraged by their superiors from hassling Saudi travelers, who were seen as big spenders. [Los Angeles Times, 1/27/2004; Time, 6/12/2005] Al-Khatani will later confess to being sent to the US by 9/11 mastermind Khalid Shaikh Mohammed (KSM) (see July 2002), and in June 2001 US intelligence was warned that KSM was sending operatives to the US to meet up with those already there (see June 12, 2001).
Mid-August 2001: 9/11 Hijacker Hanjour Rents Plane in Maryland; He Is Still Not Skilled Enough to Fly Solo
9/11 hijacker Hani Hanjour goes to the Freeway Airport in Bowie, Maryland, about 20 miles west of Washington. He wants to rent a single engine Cessna airplane. However, when two instructors take him on three test runs, they find he has trouble controlling and landing the plane. One instructor has to help him land. Due to his poor skills, therefore, he is not allowed to rent one of their planes without more lessons. Further, while Hanjour appears to have logged over 600 hours of flying experience and possesses a valid pilot’s license (though it has in fact expired), he refuses to provide contact information: He gives no phone number and only gives his address as being a hotel in Laurel. In spite of Hanjour’s lack of flying skills, chief instructor Marcel Bernard later claims, “There’s no doubt in my mind that once [Flight 77] got going, he could have pointed that plane at a building and hit it.” [Capital News, 9/19/2001; Gazette (Greenbelt), 9/21/2001; Newsday, 9/23/2001; Washington Post, 10/15/2001] However, on 9/11, in piloting Flight 77 into the Pentagon, Hanjour would have needed to do much more than simply point the plane at a target. Because Flight 77 at first seemed to overshoot its target, the Washington Post will note that “the unidentified pilot executed a pivot so tight that it reminded observers of a fighter jet maneuver. The plane circled 270 degrees to the right to approach the Pentagon from the west, whereupon Flight 77 fell below radar level.… Aviation sources said the plane was flown with extraordinary skill, making it highly likely that a trained pilot was at the helm.” [Washington Post, 9/12/2001] One Washington air traffic controller will later comment, “The speed, the maneuverability, the way that he turned, we all thought in the radar room, all of us experienced air traffic controllers, that that was a military plane.” [ABC News, 10/24/2001] One law enforcement official who will study Flight 77’s descent after 9/11 will call it the work of “a great talent… virtually a textbook turn and landing.” [Washington Post, 9/10/2002] Remarkably, the 9/11 Commission will overlook the numerous accounts of Hanjour’s terrible piloting skills (see April 15, 1999 and January-February 2001) and state that 9/11 mastermind Khalid Shaikh Mohammed assigned the Pentagon target specifically to Hanjour because he was “the operation’s most experienced pilot.” [9/11 Commission, 7/24/2004, pp. 530]
August 23, 2001: 9/11 Hijackers Alhazmi and Almihdhar Are Finally Added to Terrorist Watch List
Thanks to the request of Margaret Gillespie, an FBI analyst assigned to the CIA’s Counter Terrorism Center, the CIA sends a cable to the State Department, INS, Customs Service, and FBI requesting that “bin Laden-related individuals” Nawaf Alhazmi, Khalid Almihdhar, Ahmad Hikmat Shakir, and Salah Saeed Mohammed bin Yousaf (an alias for Khallad bin Attash) be put on the terrorism watch list. All four individuals had attended the January 2000 al-Qaeda summit in Malaysia (see January 5-8, 2000). The cable mostly focuses on Almihdhar, briefly outlining his attendance at the Malaysia summit and his subsequent travel to the US in January 2000 and July 2001. Since March 2000, if not earlier, the CIA has had good reason to believe Alhazmi and Almihdhar were al-Qaeda operatives living in the US, but apparently did nothing and told no other agency about it until now. The hijackers are not located in time, and both die in the 9/11 attacks. FBI agents later state that if they been told about Alhazmi and Almihdhar sooner, “There’s no question we could have tied all 19 hijackers together” given the frequent contact between these two and the other hijackers. [Newsweek, 6/2/2002; 9/11 Commission, 7/24/2004, pp. 538; US Department of Justice, 11/2004, pp. 32-36, 302] However, in what the Washington Post calls a “critical omission,” the FAA, the Treasury Department’s Financial Crimes Enforcement Network, and the FBI’s Financial Review Group are not notified. The two latter organizations have the power to tap into private credit card and bank data, and claim they could have readily found Alhazmi and Almihdhar, given the frequency the two used credit cards. [Washington Post, 7/25/2003] Furthermore, counterterrorism chief Richard Clarke and his Counterterrorism Security Group are not told about these two operatives before 9/11 either. [Newsweek, 3/24/2004] The CIA later claims the request was labeled “immediate,” the second most urgent category (the highest is reserved for things like declarations of war). [Los Angeles Times, 10/28/2001] The FBI denies that it was marked “immediate” and other agencies treated the request as a routine matter. [Los Angeles Times, 10/18/2001; US Congress, 9/20/2002] The State Department places all four men on the watch list the next day. [US Congress, 7/24/2003 
] However, this watch list, named TIPOFF, checks their names only if they use international flights. There is another watch list barring suspected terrorists from flying domestically. On 9/11, it contains only 12 names, including Khalid Shaikh Mohammed and other al-Qaeda figures, and some names are added as late as August 28, 2001. But none of these four men are added to this domestic list before 9/11.(see April 24, 2000). [9/11 Commission, 1/26/2004]
August 25, 2001: 9/11 Facilitator Obtains Credit Card for KSM
A supplemental Visa credit card on a “Mustafa al-Hawsawi” bank account is issued in the name of Abdulrahman A. A. al-Ghamdi, which the FBI says is an alias for Khalid Shaikh Mohammed (KSM). The FBI believes this helps prove KSM is a superior to 9/11 facilitator al-Hawsawi (see July 23, 2001). [Houston Chronicle, 6/5/2002; US Congress, 9/26/2002]
August 28, 2001: CIA Fails to Connect KSM, Bin Al-Shibh, and Moussaoui
In April 2001, the CIA analyzed some “intriguing information associated with a person known as ‘Mukhtar.’” The CIA didn’t know who this was at the time, only that he was associated with top al-Qaeda deputy Abu Zubaida and that he seemed to be involved in planning al-Qaeda activities. On August 28, 2001, the CIA receives a cable reporting that Khalid Shaikh Mohammed (KSM) has the nickname of Mukhtar (which means “brain” in Arabic). However, apparently no one at the CIA’s bin Laden unit makes the connection between this new information and the April 2001 information. The 9/11 Commission writes, “Only after 9/11 would it be discovered that Muhktar/KSM had communicated with a phone that was used by [Ramzi] bin al-Shibh, and that bin al-Shibh had used the same phone to communicate with [Zacarias] Moussaoui [who is in US custody by this time.]” [US Congress, 7/24/2003, pp. 322; 9/11 Commission, 7/24/2004, pp. 277]
Late August 2001: Al-Qaeda Hamburg Cell Member Goes to Pakistan, Possibly Tells KSM about Timing of 9/11 Attacks
Al-Qaeda Hamburg cell member Zakariya Essabar allegedly travels to Pakistan and delivers a message to al-Qaeda leaders about the timing of the 9/11 attacks. Hamburg cell member Ramzi bin al-Shibh will later be arrested and interrogated, and according to a 2005 report about his interrogations, Essabar delivers the simple message “eleven nine.” Most countries around the world, including Muslim countries, put the day before the month, so this is a reference to September 11, the date of the upcoming 9/11 attacks. This message is supposed to be sent to someone with the name Mukhtar in Pakistan. Mukhtar is a commonly used alias of 9/11 mastermind Khalid Shaikh Mohammed (KSM) (see August 28, 2001), and he is in Karachi, Pakistan, at the time (see Early September 2001), so this is likely a reference to him. But Essabar apparently is unable to quickly find KSM, and he calls bin al-Shibh in Germany to say he is having trouble finding him. Presumably, bin al-Shibh loses contact with Essabar after this, so it is unclear what happens to the message. [Washington Post, 5/24/2005] However, it is unclear how reliable bin al-Shibh’s claims may be, especially since he may be tortured later. Bin al-Shibh will give conflicting information about Essabar. At one point, he claims he knows nothing about Essabar at all. At another point, he claims that al-Qaeda leader Mohammed Atef told Essabar to try to acquire a US visa, but did not explain why, and Essabar had no foreknowledge of the 9/11 attacks. But at another point, he claims that Essabar was told the get the US visa so he “could travel to the United States to take part in the planned attacks.” [Reuters, 5/21/2005; Washington Post, 5/24/2005] While it may be uncertain if Essabar delivers a message on the timing of the 9/11 attacks, it is highly likely that he does flee to Afghanistan at this time. Others will later say they see him at an al-Qaeda training camp in Afghanistan in late September 2001 (see September 10, 2001). His whereabouts after then will be unknown.
Before September 11, 2001: FBI Squad Builds Antenna to Listen in on KSM’s Phone Calls
I-49, a squad of FBI agents and Justice Department prosecutors that began focusing on bin Laden in 1996 (see January 1996), is upset that the NSA is not sharing its monitoring of the phone calls of Khalid Shaikh Mohammed (KSM). The squad builds their own antenna in Madagascar specifically to intercept KSM’s calls. [Wright, 2006, pp. 344] It has not been revealed when this antenna was built or what was learned from this surveillance. However, there have been media reports that the NSA monitored some phone calls between KSM and Mohamed Atta in the summer of 2001 (see Summer 2001). Further, US intelligence monitored a call between KSM and Atta a day before 9/11 that was the final go-ahead for the attacks (see September 10, 2001). So presumably the I-49 squad should have known about these calls as well if this antenna did what it was designed to do.
Early September 2001: Hambali Aware of Attack Date for 9/11 Plot
Hambali, a top al-Qaeda leader in Southeast Asia, appears aware of the date of the 9/11 attacks. Mohammed Mansour Jabarah, a young Canadian citizen who recently joined al-Qaeda, meets Hambali in Karachi, Pakistan, to get instructions in carrying out an attack in Southeast Asia. Hambali tells him, “Make sure you leave before Tuesday” – September 11. Jabarah does heed the warning and flies to Southeast Asian on September 10. He will be arrested in 2002 and deported to Canada, where he will make a full confession about his al-Qaeda contacts (including an unheeded warning about the October 2002 Bali bombings (see August 21, 2002). [National Post, 1/18/2003] Khalid Shaikh Mohammed (KSM) is also in Karachi and working with Jabarah and Hambali on future Southeast Asian plots, and KSM also warns Jabarah to travel before September 11. [CBC News, 10/2004]
September 4-5, 2001: Operatives Connected to 9/11 Meet in Karachi
Several al-Qaeda operatives connected to the 9/11 plot appear to have a meeting in Karachi, possibly to finalize details related to the plot. Some of the operatives arrive from Germany, via Istanbul, by plane (see September 3-5, 2001). They include Said Bahaji, an associate of the hijackers, Afghan brothers Mohammad Sarwar Joya and Patrick Joya, an Algerian named Mohammed Belfatmi who also just arrived on the same Istanbul to Karachi leg of the flight as the others. Belfatmi is said to have had a role in arranging a meeting in Spain between 9/11 hijacker Mohamed Atta and would-be hijacker Ramzi bin al-Shibh (see July 8-19, 2001). Men known as Abdellah Hosayni and Ammar Moul are also on the flight from Germany. However, these last two apparently are traveling under false identities, and it will later be reported that they are really Ismail Bin Murabit (a.k.a. Ismail Ben Mrabete) and Labed Ahmed (a.k.a. Ahmed Taleb). An informer later says both Murabit and Ahmed attended the same al-Qaeda training camp as Bahaji. All five of these men – Bahaji, Murabit, Ahmed, the Joya brothers, and Belfatmi – stay in the same hotel once they arrive in Karachi. [Fortune, 10/30/2001; CNN, 10/31/2001; Chicago Tribune, 2/25/2003] Ahmed is suspected by German investigators of having a “major role” in preparations for 9/11. [CNN, 10/31/2001] A Pakistani newspaper will say that, “It was, in all probability, a meeting to tie up loose ends before the countdown to the attack.” [Pioneer, 8/7/2003] Khalid Shaikh Mohammed and Hambali are in Karachi at this time, although it is unclear whether they meet with Bahaji and the others (see Early September 2001). The Joya brothers, who are apparently under surveillance by German police around this time, return to Istanbul on October 5 and 16. In Germany in late October, Patrick Joya will even talk to a reporter and admit recently traveling to Pakistan. [Fortune, 10/30/2001; CNN, 10/31/2001; Chicago Tribune, 2/25/2003] What happens to the Joya brothers after this time is unclear. Ahmed will later be arrested in the same raid that nabs al-Qaeda leader Abu Zubaida, and he will be sent to the US-run Guantanamo prison (see March 28, 2002).
September 5, 2001: Hijacker Associate Ramzi Bin Al-Shibh in Germany Calls 9/11 Hijacker in US; His Calls May Be Monitored
Would-be hijacker Ramzi bin al-Shibh makes three phone calls on this day, and one is to 9/11 hijacker Saeed Alghamdi in the US. Bin al-Shibh makes the three calls from the airport in Dusseldorf, Germany, as he is about to take a flight to Spain on his way to Pakistan (see September 5, 2001). Nothing more is known about the call to Alghamdi. However, the call may be an opportunity to discover the 9/11 plot, because at least some of bin al-Shibh’s phone calls are monitored around this time. Details are murky, but a call between bin al-Shibh and 9/11 mastermind Khalid Shaikh Mohammed is monitored in late July 2001, although it is not clear if it is monitored by US or German intelligence, or both (see July 20, 2001).
Second Call to Jordanian – At the airport, bin al-Shibh also calls an unnamed Jordanian who is said to be a close friend of 9/11 hijacker Ziad Jarrah from a time both of them were studying in Griefswald, Germany, in the mid-1990s. This person lived in the same Hamburg apartment as hijacker Mohamed Atta, was said to have become an Islamist radical, and shared bank accounts and cell phone numbers with some of the hijackers living in Hamburg. [Chicago Tribune, 2/25/2003] This almost certainly is Bashir Musleh, because Musleh is a Jordanian who is a close friend of Jarrah’s from when they both studied in Griefswald. Author Terry McDermott identifies him as one of the Hamburg group. [McDermott, 2005, pp. xi, 53]
Third Call to Cell Member Meziche – The third and final call is to Naamen Meziche, a French citizen of Algerian descent, and a longtime resident of Hamburg, Germany. The call to Meziche’s house lasts 34 seconds. Meziche appears to be a member of the al-Qaeda Hamburg cell, but German investigators will never be able to develop enough evidence to charge him with a crime. He will be killed in a drone strike in Pakistan in 2010 (see October 5, 2010). [Wall Street Journal, 10/16/2010]
