An FBI agent assigned to the CIA’s bin Laden unit locates a CIA cable that says 9/11 hijacker Khalid Almihdhar has a US visa, but fails to disseminate the information to the FBI. It is not clear why the agent, Margaret Gillespie, fails to do this. However, at the same time she locates another CIA cable which mistakenly states that the information about the visa has already been passed to the FBI (see 9:30 a.m. – 4:00 p.m. January 5, 2000).

August 2001: Six 9/11 Hijackers Live Near Entrance to NSA
At least six 9/11 hijackers, including all of those who boarded Flight 77, live in Laurel, Maryland, from about this time. They reportedly include Hani Hanjour, Majed Moqed, Khalid Almihdhar, Nawaf Alhazmi, and Salem Alhazmi. Laurel, Maryland, is home to a Muslim imam named Moataz Al-Hallak who teaches at a local Islamic school and has been linked to bin Laden. He has testified three times before a grand jury investigating bin Laden. NSA expert James Bamford later states, “The terrorist cell that eventually took over the airliner that crashed into the Pentagon ended up living, working, planning and developing all their activities in Laurel, Maryland, which happens to be the home of the NSA. So they were actually living alongside NSA employees as they were plotting all these things.” [Washington Post, 9/19/2001; Radio 4 ‘Today’, 6/21/2002]
August 2001: NSA Intercepts Another Call between Yemen Hub and 9/11 Hijackers Alhazmi and Almihdhar in US
The NSA has been intercepting calls between at least two 9/11 hijackers, Nawaf Alhazmi and Khalid Almihdhar, in the US and an al-Qaeda communications hub in Sana’a, Yemen, run by al-Qaeda operative Ahmed al-Hada over an approximately 18-month period before 9/11 (see Early 2000-Summer 2001). According to MSNBC, the final intercepted call comes “only weeks” before 9/11. [MSNBC, 7/21/2004] Around the same time there is great alarm in the US intelligence community over a communications intercept in Yemen indicating there was going to be a major al-Qaeda attack against US interests (see June 30-July 1, 2001). Further, the investigation of the USS Cole bombing has reignited interest in Almihdhar and Alhazmi on the part of the US intelligence community since at least June 2001 (see June 11, 2001 and July 13, 2001). The two of them are placed on an international no-fly list in late August (see August 23, 2001).
August 1, 2001: Actor Communicates Concerns to Stewardess that Airplane Will Be Hijacked; Warning Forwarded to the FAA
Actor James Woods, flying first class on an airplane, notices four Arabic-looking men, the only other people in the first class section. He concludes they are Islamic militants intent on hijacking the plane, acting very strangely (for instance, only talking in whispers). [Boston Globe, 11/23/2001] He tells a flight attendant, “I think this plane is going to be hijacked,” adding, “I know how serious it is to say this.” He conveys his worries to the pilots, and they assure him that the cockpit would be locked. [New Yorker, 5/27/2002] The flight staff later notifies the FAA about these suspicious individuals. Though the government will not discuss this event, it is highly unlikely that any action is taken regarding the flight staff’s worries [New Yorker, 5/27/2002] Woods will not be interviewed by the FBI until after 9/11. Woods will say the FBI believes that all four men took part in the 9/11 attacks, and the flight he was on was a practice flight for them. [O’Reilly Factor, 2/14/2002] Woods believes one was Khalid Almihdhar and another was Hamza Alghamdi. [New Yorker, 5/27/2002] The FBI later will report that this may have been one of a dozen test run flights starting as early as January (see May 24-August 14, 2001). Flight attendants and passengers on other flights later recall men looking like the hijackers who took pictures of the cockpit aboard flights and/or took notes. [Associated Press, 5/28/2002] The FBI has not been able to find any evidence of hijackers on the flight manifest for Woods’ flight. [New Yorker, 5/27/2002]
August 1-2, 2001: Hijackers Illegally Purchase Virginia Identity Cards
Hijackers Hani Hanjour and Khalid Almihdhar meet Luis Martinez-Flores, an illegal immigrant from El Salvador, in a 7-Eleven parking lot in Falls Church, Virginia. Martinez-Flores is paid $100 cash to accompany the two to a local Department of Motor Vehicles office and sign forms attesting to their permanent residence in Virginia. Given new state identity cards, the cards are used the next day to get Virginia identity cards for several (five to seven) additional hijackers, including Abdulaziz Alomari, Ahmed Alghamdi, Majed Moqed, and Salem Alhazmi.

August 13-14, 2001: 9/11 Hijackers Meet in Las Vegas for Summit
The lead hijackers meet in Las Vegas for a summit a few weeks before 9/11. Investigators will believe that this is the “most crucial planning in the United States,” but will not understand why the hijackers choose Vegas, since they are all living on the East Coast at this time (see March 2001-September 1, 2001 and August 6-September 9, 2001). One senior official will speculate, “Perhaps they figured it would be easy to blend in.” [New York Times, 11/4/2001] At least three of the plot leaders are in Las Vegas at this time. Hani Hanjour and Nawaf Alhazmi fly from Dulles Airport to Los Angeles on an American Airlines Boeing 757, the same sort of plane they hijack on 9/11, and then continue to Las Vegas. Mohamed Atta also flies to Las Vegas from Washington National Airport. This is his second trip to Vegas, which was also previously visited by some of the other hijackers (see May 24-August 14, 2001). A few weeks earlier, Atta had traveled to Spain, possibly with some of the other hijackers, to finalize the plans for the attack with their associate Ramzi bin al-Shibh (see July 8-19, 2001). [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006, pp. 1, 17, 21 ; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006, pp. 57-8 ] Alhazmi will later be recalled by a hotel employee, who will say she ran into him at the Days Inn. According to her later account, he is “cold and abrupt,” in Vegas on “important business,” and will soon be traveling to Los Angeles. He asks for a list of Days Inns in Los Angeles, but does not want a reservation to be made. He also claims to be from Florida, although he is only thought to have spent a week there (see June 19-25, 2001). [Las Vegas Review-Journal, 10/26/2001] A close associate of the hijackers, Ramzi bin al-Shibh, will later say in a 2002 interview that Ziad Jarrah, Marwan Alshehhi, and Khalid Almihdhar are also present in Vegas at this time. [Fouda and Fielding, 2003, pp. 137] Newsweek calls Vegas an “odd location” and comments: “They stayed in cheap hotels on a dreary stretch of the Strip frequented by dope dealers and $10 street hookers. Perhaps they wished to be fortified for their mission by visiting a shrine to American decadence. Or maybe they just wanted a city that was easy to reach by air from their various cells in Florida, New Jersey and San Diego.” [Newsweek, 10/15/2001]
August 16, 2001: Moussaoui’s Belongings Possess Information Sufficient to Roll Up 9/11 Plot
After Zacarias Moussaoui is arrested, the FBI wishes to search his possessions (see August 16, 2001 and August 23-27, 2001). According to a presentation made by FBI agent Aaron Zebley at Moussaoui’s trial, the belongings are sufficient to potentially connect Moussaoui to eleven of the 9/11 hijackers: Mohamed Atta, Marwan Alshehhi, Ziad Jarrah, Hani Hanjour, Khalid Almihdhar, Nawaf Alhazmi, Fayez Banihammad, Ahmed Alhaznawi, Hamza Alghamdi, Satam Al Suqami, and Waleed Alshehri. The connections would be made, for example, through Ramzi bin al-Shibh, who spoke with Moussaoui on the telephone and wired him money (see July 29, 2001-August 3, 2001), and who was linked to three of the hijacker pilots from their time in Germany together (see November 1, 1998-February 2001). Bin al-Shibh also received money from Mustafa Ahmed al-Hawsawi, who was connected to hijacker Fayez Ahmed Banihammad (see June 25, 2001). [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] Moussaoui’s notebook contained two recognizable control numbers for the Western Union wire transfers from bin al-Shibh and, according to McClatchy newspapers, a check on these numbers “would probably have uncovered other wires in the preceding days” to bin al-Shibh from al-Hawsawi. [McClatchy Newspapers, 9/11/2007] The discovery of the eleven hijackers could potentially have led to the discovery of some or all of the remaining eight plot members, as they were brothers (Wail and Waleed Alshehri, Nawaf and Salem Alhazmi), opened bank accounts together (see May 1-July 18, 2001 and June 27-August 23, 2001), lived together (see March 2001-September 1, 2001), obtained identity documents together (see April 12-September 7, 2001 and August 1-2, 2001), arrived in the US together (see April 23-June 29, 2001), and booked tickets on the same four flights on 9/11 (see August 25-September 5, 2001).
August 16-September 10, 2001: 9/11 Hijackers Make Series of Deposits to Bank Accounts
Several deposits are made to the 9/11 hijackers’ accounts. Details are available for some of the deposits for eleven of the nineteen hijackers: Mohamed Atta, Marwan Alshehhi, Ziad Jarrah, Hani Hanjour, Nawaf Alhazmi, Khalid Almihdhar, Ahmed Alhazmawi, Fayez Ahmed Banihammad, Hamza Alghamdi, Waleed Alshehri, and Satam Al Suqami. Over $40,000 is deposited in their accounts, much in cash. The largest amounts deposited in one day occur on August 24, when $8,000 is split equally between Hamza Alghamdi’s account and a joint account of Atta and Alshehhi, and September 5, when a total of $9,650 is split between Banihammad’s and Hamza Alghamdi’s accounts, and the joint Atta/Alshehhi account. The smallest deposit is $120, paid into Khalid Almihdhar’s First Union National Bank account on September 9. [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006 ; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006 ; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006 ; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006 ; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006 ; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006 ; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006 ; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006 ; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006 ] Although it is impossible to trace the exact origins of the deposits, possible sources include withdrawals from other hijackers’ bank accounts, cash and traveler’s checks brought in by the hijackers in the spring/early summer (see January 15, 2000-August 2001), car sales, and money distributed by Atta, who reportedly received around $100,000 in early August (see Early August 2001, Summer 2001 and before, and Mid-July-Mid-August 2001).
Before August 22, 2001: Threat Information about ‘Khalid’ Increases Interest in 9/11 Hijacker Almihdhar
The CIA receives some threat information about a man named “Khalid” and begins to examine data on everybody it knows whose first name is “Khalid”. In an August 22 e-mail FBI agent Dina Corsi writes that this is one of the reasons for the interest in hijacker Khalid Almihdhar at this time: “the reason [the intelligence community] were looking at [Almihdhar] is relatively general—basically they were looking at all individuals using the name Khalid because of some threat information.” [US Department of Justice, 11/2004, pp. 285 ] The identity of the man named Khalid they are looking for is not revealed, however, there is threat reporting starting in June 2001 concerning someone an informant called Khalid, who is later revealed to be Khalid Shaikh Mohammed (see June 12, 2001).
August 21-22, 2001: FBI Agents Finally Realize 9/11 Hijacker Almihdhar Is in US
An FBI agent detailed to the CIA’s bin Laden unit locates CIA cables saying that future 9/11 hijacker Nawaf Alhazmi entered the US in early 2000. The agent, Margaret Gillespie, then checks with the US Customs Service and discovers that another future 9/11 hijacker, Khalid Almihdhar, entered the US on July 4, 2001, and there is no record he has left the country. As there is “an imperative to find anyone affiliated with al-Qaeda if they [are] believed to be in the US,” Gillespie immediately contacts Dina Corsi, an FBI agent in its bin Laden unit. Gillespie, who has been examining the USS Cole bombing and al-Qaeda’s Malaysia summit for some time, will later say that when she learns of their arrival in the US, “it all clicks for me.” The Justice Department’s office of inspector general will find that Gillespie’s “actions on receipt of the information clearly indicate that she understood the significance of this information when she received it. She took immediate steps to open an intelligence investigation.” Gillespie and Corsi meet with Tom Wilshire, a CIA officer involved in the investigation (see August 22, 2001), and Almihdhar and Alhazmi are soon watchlisted (see August 23, 2001).
