Future 9/11 hijacker Mohamed Atta and other members of the Hamburg cell begin regularly attending the Al-Quds mosque. Atta becomes a well-known figure both there and at other mosques in the city. He grows a beard at this time, which some commentators interpret as a sign of greater religious devotion. The mosque is home to numerous radicals. For example, the imam, Mohammed Fazazi, advocates killing non-believers and encourages his followers to embrace martyrdom (see 1993-Late 2001 and Early 2001).
Atta Teaches Classes at Al-Quds – After a time, Atta begins to teach classes at the mosque. He is stern with his students and criticizes them for wearing their hair in ponytails and gold chains around their necks, as well as for listening to music, which he says is a product of the devil. If a woman shows up, her father is informed she is not welcome. This is one of the reasons that, of the 80 students that start the classes, only a handful are left at the end.
Other Hijackers and Cell Members Attend Al-Quds – One of Atta’s associates, Ramzi bin al-Shibh, also teaches classes at the mosque. 9/11 hijackers Marwan Alshehhi and Ziad Jarrah start attending the mosque at different times and possibly first meet Atta there. Other mosque attendees who interact with the future hijackers at the mosque include Said Bahaji, and al-Qaeda operatives Mamoun Darkazanli and Mohammed Haydar Zammar.
Is the Mosque Monitored? – According to author Terry McDermott, German investigators notice Bahaji meeting frequently with Darkazanli and Zammar at the mosque, so they presumably have a source inside it. [PBS Frontline, 1/2002; Burke, 2004, pp. 242; McDermott, 2005, pp. 1-5, 34-37, 72] The German newspaper Frankfurter Allgemeine Zeitung will later report that there probably is an informer working for the LfV, the Hamburg state intelligence agency, inside the mosque by 1999. Somehow, the LfV is very knowledgeable about Atta and some his associates, and their behavior inside the mosque (see (April 1, 1999)). [Frankfurter Allgemeine Zeitung (Frankfurt), 2/2/2003] Radical imam Fazazi will continue to preach at the mosque until late 2001 (see Mid-September-Late 2001).
April 11, 1996: 9/11 Hijacker Atta Makes Will
Future 9/11 hijacker Mohamed Atta makes his will in Germany. It is not clear that the text of the will is actually written by Atta. For example, author Lawrence Wright will say that Atta merely signs a “standardized will” he gets from the Al-Quds mosque in Hamburg, and journalists Yosri Fouda and Nick Fielding will say that the will is a “printed-out form devised by the mosque.” Atta apparently makes it as he is angered by new reports of an Israeli operation against Lebanon, which begins on this day. [Fouda and Fielding, 2003, pp. 81-2; Wright, 2006, pp. 307] Although the act of making a will is not that unusual for a 27-year old Muslim, the content of the will is unusual, perhaps reflecting the radical environment of the mosque (see Early 1996). For example, it says: “… [6] I don’t want a pregnant woman or a person who is not clean to come and say good bye to me because I don’t approve it… [9] The person who will wash my body near my genitals must wear gloves on his hands so he won’t touch my genitals… [11] I don’t want any women to go to my grave at all during my funeral or on any occasion thereafter.” The will is witnessed by Abdelghani Mouzdi and Mounir El Motassadeq, who also make wills around the same time. [Atta, 4/11/1996; Burke, 2004, pp. 242; McDermott, 2005, pp. 49, 245-7, 274]
1997 or 1998: 9/11 Hijacker Atta in Two Places at Once?
Spanish newspaper El Mundo later reports, “According to several professors at the Valencia School of Medicine, some of whom are forensic experts, [9/11 hijacker Mohamed Atta] was a student there in 1997 or 1998. Although he used another name then, they remember his face among the students that attended anatomy classes.” It is also suggested that “years before, as a student he went to Tarragona. That would explain his last visit to Salou [from July 8-19, 2001], where he could have made contact with dormant cells…”(see July 8-19, 2001) [El Mundo (Madrid), 9/30/2001] If this is true, it would contradict reports concerning Atta’s presence as a student in Hamburg, Germany, during this entire period. There is also a later report that in 1999 Atta will meet an al-Qaeda operative in Alicante, less than 100 miles from Valencia (see 1999).
1997: Monitored Al-Qaeda Operative Zammar Frequently Seen with 9/11 Hijacker Atta
Al-Qaeda operative Mohammed Haydar Zammar is frequently seen with future 9/11 hijacker Mohamed Atta starting this year. According to Time magazine: “Beginning in 1997, neighbors of Atta’s would often see Zammar carrying boxes up to the Egyptian student’s second-story walk-up. US investigators believe he may have persuaded Atta’s Islamic study group to offer its services to al-Qaeda around 1998.” [Time, 7/1/2002] German intelligence begins heavily monitoring Zammar in early 1997 (see March 1997-Early 2000), but it is unclear when it first takes notice of Atta.
1997-1999: Hamburg Cell Members Work at Local Computer Company
9/11 hijacker Mohamed Atta, fellow plotter Ramzi bin al-Shibh, and two of their associates, Mohammed Haydar Zammar and Mohammed Belfas, find employment at a small Hamburg-area computer company called Hay Computing Service GmbH. [Federal Bureau of Investigation, 1/11/2002, pp. 30; Federal Bureau of Investigation, 4/19/2002] Hijacker Marwan Alshehhi also reportedly works there. [Waterloo Courier, 12/30/2001] Atta and Belfas got their jobs through Agus Budiman, an Indonesian associate of theirs, who was already employed at the company. [9/11 Commission, 1/28/2004 
] Another unnamed individual, who will be investigated after 9/11, also works there with bin al-Shibh. [9/11 Commission, 11/6/2003] The cell members work in the company’s warehouse, packing computers for shipment. [Wall Street Journal, 10/9/2001; Fouda and Fielding, 2003, pp. 123; Der Spiegel (Hamburg), 9/8/2003]
Late 1997-Early 1998: 9/11 Hijacker Atta Disappears from Germany for Months; He Possibly Trains in Afghanistan with Bin Al-Shibh
Future 9/11 hijacker Mohamed Atta leaves Hamburg for some time in late 1997 and early 1998, and he may go to militant training camps in Afghanistan, possibly with hijacker associate Ramzi bin al-Shibh. When Atta returns in the spring of 1998 he tells his roommate that he has been on another pilgrimage (hajj) to Mecca, although author Terry McDermott will later note, “He had been on hajj just 18 months earlier, and it would be unlikely for a student—even one so devout—to go twice so quickly or stay so long.” This is Atta’s longest absence since arriving in Hamburg, and there is no record of him spending any substantial portion of it at home in Cairo. According to McDermott, he leaves Hamburg “as he usually did over the winter holiday.” [McDermott, 2005, pp. 57] But according to the 9/11 Commission, the gap is in February-March 1998, “a period for which there is no evidence of his presence in Germany.” Atta’s friends hold a party for him on his return, which is unusual for a student who has just returned from home. After returning to Germany, Atta applies for a new passport, something he will also do after returning from Afghanistan in early 2000 (see Late 1999). [9/11 Commission, 7/24/2004, pp. 167] There are other unexplained absences from Hamburg by members of the same cell around this time (see Summer-Winter 1998). Although the 9/11 Commission, based on information obtained from detainees during interrogation, will say that Atta and his associates do not travel to Afghanistan and join al-Qaeda until late 1999, some commentators will disagree and say that this happens earlier. [McDermott, 2005, pp. 57] For example, McDermott will say of the cell members’ various disappearances in 1997-8, “Practically, there is only one place they likely would have gone—Afghanistan.” [9/11 Commission, 7/24/2004, pp. 166] Jane Corbin will say that “[t]he time that Mohamed Atta spent in Afghanistan in 1998 was a period of ambitious reach for Osama bin Laden.” [Corbin, 2003, pp. 142] Jason Burke will say that “[i]n early 1998, [Atta] is thought to have traveled to Afghanistan, probably to Khaldan camp.” [Burke, 2004, pp. 243] In mid-2002, Al Jazeera reporter Yosri Fouda will allegedly interview bin al-Shibh and 9/11 mastermind Khalid Shaikh Mohammed in Pakistan (see April, June, or August 2002). In a book he co-writes in 2003, he will claim that an al-Qaeda operative known only by a nickname Fouda gave him so he could call him something—Abu Bakr—helped set up the interview. At one point, Bakr allegedly told Fouda that he met Atta and bin al-Shibh at a training camp around this time, saying: “They came together. I did not know who they were.… Brother Ramzi was very active and very much into media, and brother Atta was very kind.” Bin al-Shibh disappears in Germany for several months in late 1997, and re-enters Germany on a new visa in December 1997. [Fouda and Fielding, 2003, pp. 124]
1998: 9/11 Hijacker Atta Possibly Trains at Base Conducting Pilotless Aircraft Exercises
A military report released this year describes the “Joint Vision 2010” program, a series of “analyses, war games, studies, experiments, and exercises” which are “investigating new operational concepts, doctrines, and organizational approaches that will enable US forces to maintain full spectrum dominance of the battlespace well into the 21st century.”
“The Air Force has begun a series of war games entitled Global Engagement at the Air War College, Maxwell Air Force Base, Alabama.” The same report mentions that the military is working on a “variety of new imaging and signals intelligence sensors, currently in advanced stages of development, deployed aboard the Global Hawk, DarkStar, and Predator unmanned aerial vehicles (UAVs)…” [US Department of Defense, 1998] Global Hawk is a technology that enables pilotless flight and has been functioning since at least early 1997. [US Department of Defense, 2/20/1997] While it may be mere coincidence, “Air Force spokesman Colonel Ken McClellan said a man named Mohamed Atta—which the FBI has identified as one of the five hijackers of American Airlines Flight 11—had once attended the International Officer’s School at Maxwell/Gunter Air Force Base in Montgomery, Ala.” But he adds that “there [was] discrepancies in the biographical data” (mainly the birth date) and that “it may just be a case of mistaken identity” (see also 1996-August 2000 and September 15-17, 2001) [Gannett News Service, 9/17/2001; Gannett News Service, 9/20/2001]
Summer 1998: Al-Qaeda 9/11 Cell Coalesces in Hamburg
Future 9/11 hijacker Mohamed Atta and a group of his radical Islamist friends move into an apartment in Wilhelmsburg, an island on the Elbe River in the middle of Hamburg, Germany. The area is a run-down industrial zone. It is unclear who all the members of the group living in the apartment are, but Marwan Alshehhi and Ramzi bin al-Shibh live there. For the first time, this group becomes very closely tied together. They live an extremely simple life, with nothing but mattresses for furniture and no electrical devices except for lights. Neighbors will later say the men in the apartment talk long into the night nearly every night, with the blinds on the windows permanently closed. The group moves to a nicer apartment on November 1, 1998 (see November 1, 1998-February 2001). [McDermott, 2005, pp. 58-60]
July 7, 1998: Stolen Passport Links 9/11 Hijackers and Spanish Terrorist Cells
Thieves snatch a passport from a car driven by a US tourist in Barcelona, Spain, which later finds its way into the hands of would-be hijacker Ramzi Bin al-Shibh. Bin al-Shibh allegedly uses the name on the passport in the summer of 2001 as he wires money to pay flight school tuition for Zacarias Moussaoui in Oklahoma (see July 29, 2001-August 3, 2001). After 9/11, investigators will believe the movement of this passport shows connections between the 9/11 plotters in Germany and a support network in Spain, made up mostly by ethnic Syrians. “Investigators believe that the Syrians served as deep-cover mentors, recruiters, financiers and logistics providers for the hijackers—elite backup for an elite attack team.” [Los Angeles Times, 1/14/2003] Mohamed Atta travels to Spain twice or three times in 2001 (see January 4-10, 2001, July 8-19, 2001, and September 5, 2001), perhaps to make contact with members of this Spanish support team.
November 1, 1998-February 2001: 9/11 Hijacker Atta and Associates Are Monitored Some by US and Germany in Their Hamburg Apartment
Future 9/11 hijacker Mohamed Atta, al-Qaeda operatives Said Bahaji and Ramzi Bin al-Shibh, and others in the al-Qaeda Hamburg cell move into a four bedroom apartment at 54 Marienstrasse, in Hamburg, Germany, and some of them stay there until February 2001. Investigators will later believe this move marks the formation of the Hamburg al-Qaeda cell. [Los Angeles Times, 1/27/2002; New York Times, 9/10/2002] Up to six men at a time live at the apartment, including, at times, 9/11 hijacker Marwan Alshehhi and cell member Zakariya Essabar. Alshehhi moves out after the first month; it is unclear why. [New York Times, 9/15/2001] During the 28 months Atta’s name is on the apartment lease, 29 Middle Eastern or North African men register the apartment as their home address.
Surveillance of Bahaji – From the very beginning, the apartment is under surveillance by German intelligence, because of investigations into businessman Mamoun Darkazanli that connect to Bahaji. [Washington Post, 10/23/2001] The Germans also suspect connections between Bahaji and al-Qaeda operative Mohammed Haydar Zammar. [Los Angeles Times, 9/1/2002] Bahaji is directly monitored for at least part of 1998, but German officials will not disclose when the probe began or ends. This investigation is dropped for lack of evidence (see (Late 1998)). [Associated Press, 6/22/2002; Los Angeles Times, 9/1/2002] Bahaji moves out in July 1999 and gets married a few months later (see October 9, 1999). [Der Spiegel (Hamburg), 8/29/2011]
Surveillance of El Motassadeq – German intelligence monitors the apartment off and on for months, and wiretaps Mounir El Motassadeq, an associate of the apartment-mates who will later be convicted for assisting the 9/11 plot, but apparently it does not find any indication of suspicious activity (see August 29, 1998). [Chicago Tribune, 9/5/2002]
Surveillance of Zammar – Zammar, a talkative man who has trouble keeping secrets, does not live at the apartment, but he is a frequent visitor to the many late night meetings there. [Miller, Stone, and Mitchell, 2002, pp. 259-60; Los Angeles Times, 9/1/2002; Chicago Tribune, 9/5/2002] He even lives in the apartment for a time in February 1999 (see February 1999). Zammar is the focus of an investigation that began in 1997 and continues until early 2000 (see March 1997-Early 2000). Interest in monitoring him increases in late 1998 (see October 2, 1998).
Surveillance of Atta – The CIA also allegedly starts monitoring Atta in early 2000 while he is living at the apartment, and does not tell Germany of the surveillance (see January-May 2000). Atta leaves Germany to live in the US in June 2000 (see June 3, 2000).
No Direct German Surveillance of the Apartment? – Yet, even though people like Zammar who frequently phone and visit the apartment are monitored, German officials will later claim that the apartment itself is never bugged. An unnamed senior German security official will later say that some surveillance of associated people gives “the impression that the people living there were fanatical believers. At the BfV [Germany’s domestic intelligence agency], we had to decide whether to ask permission to place a wiretap on the line at 54 Marienstrasse itself. We discussed this every day.” But he will claim that they ultimately decide they will not be able to get legal permission for a wiretap because there is no evidence that the apartment’s occupants are breaking any laws. [Vanity Fair, 11/2004] This claim that the apartment was not directly monitored seems contradicted by reports that Bahaji was the target of a surveillance investigation when he was living in the Marienstrasse apartment in late 1998 (see (Late 1998)).
What Would More Surveillance Have Uncovered? – It will later be clear that investigators could have found evidence if they looked more thoroughly. For instance, one visitor will recall Atta and others discussing attacking the US. [Knight Ridder, 9/9/2002] 9/11 mastermind Khalid Shaikh Mohammed is in Hamburg several times in 1999 and comes to the apartment. However, although there is a $2 million reward for Mohammed since 1998, the US apparently fails to tell Germany what it knows about him (see 1999). [Newsweek, 9/4/2002; New York Times, 11/4/2002] 9/11 Hijacker Waleed Alshehri also apparently stays at the apartment “at times.” [Washington Post, 9/14/2001; Washington Post, 9/16/2001] Remarkably, shortly after 9/11, the German government will claim it knew little about the Hamburg al-Qaeda cell before 9/11, and nothing directed it towards the Marienstrasse apartment. [Daily Telegraph, 11/24/2001]
