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 25, 2001: Bin Laden Publicly Hints at Attack on US
Bin Laden gives an interview to a Middle Eastern television station visiting him in Afghanistan. According to ABC News, “When asked about his supporters, he says with a significant and knowing smile there is going to be a surprise to the United States.” [ABC News, 9/14/2001]
Late August-Early September 2001: 9/11 Hijacker Atta Receives Money from Egypt
9/11 hijacker Mohamed Atta receives two wire transfers from Egypt through a small Florida money-wiring business. [Time, 10/1/2001] These transfers are not mentioned by the 9/11 Commission. [9/11 Commission, 7/24/2004; 9/11 Commission, 8/21/2004 
] Atta, an Egyptian, was in contact with his family in Cairo, Egypt, about once a month while he was in the US, although his father subsequently claimed not to know he was there (see September 19, 2001). Atta celebrates his birthday roughly around this time, on August 27 (8 Jumada al-Thani 1388 A.H.) or September 1, depending on whether he was going be the Muslim or Western calendar.

Late August-Early September 2001: FBI Fails to Ask Failed Millennium Bomber to Identify Moussaoui
The FBI fails to ask Ahmed Ressam, an al-Qaeda operative arrested during the Millennium alert (see December 14, 1999), whether he can identify Zacarias Moussaoui. Agents in Seattle holding Ressam receive a general notification about the Moussaoui case, but it lacks urgency and they do not follow up on it with Ressam (see September 4, 2001). When asked shortly after 9/11, Ressam will say he recognizes Moussaoui from al-Qaeda’s training camps in Afghanistan. The 9/11 Commission will conclude that had Ressam been shown photos of Moussaoui and identified him before 9/11, the FBI would have been able to search his belongings. The belongings contain enough information to potentially prevent 9/11 (see August 16, 2001). The FBI also fails to ask Ressam whether he recognizes Khalid Almihdhar at this time, although Ressam has never met Almihdhar and will not identify him after 9/11 (see August 21, 2001).

August 25, 2001: 9/11 Hijacker Alhazmi Possibly Calls Associate in San Diego and Tells Him of 9/11 Attacks Date
Around August 25, 2001, future 9/11 hijacker Nawaf Alhazmi possibly calls Mohdar Abdullah, a close associate of his when he lived in San Diego in 2000, and tells him about the 9/11 attacks date. 
Shortly after 9/11, the FBI will question Abdullah about getting a call from Alhazmi in August; it is unclear how the FBI would have known to ask that question. In a July 2002 interview with the FBI, Abdullah will ask if the FBI taped the phone call, suggesting that it does take place. In 2003, Abdullah will be in a US jail, and another prisoner will claim Abdullah says he found out about the 9/11 attacks three weeks in advance. Abdullah stops making calls from his phone after August 25, 2001. After 9/11, Abdullah’s friends will say that Abdullah starts acting strangely around this time. [9/11 Commission, 7/24/2004, pp. 218, 531] According to a witness, one day before 9/11, Abdullah and some of his co-workers (who are themselves radical Islamists (see Autumn 2000)) will appear to celebrate the upcoming 9/11 attacks, and one of them says, “It is finally going to happen” (see Late August-September 10, 2001).
In 2003 and 2004, more evidence will emerge that Abdullah willingly took part in the 9/11 plot, but he will be deported anyway (see September 2003-May 21, 2004 and May 21, 2004).
August 25-27, 2001: Hijackers Alhazmi and Almihdhar Buy 9/11 Plane Tickets Despite Presence on Watch List
Hijacker Khalid Almihdhar buys his 9/11 plane ticket on-line using a credit card; hijacker Nawaf Alhazmi does the same two days later, and also buys a ticket for his brother Salem (see August 25-September 5, 2001). Both men were put on a terrorist watch list on August 23 (see August 23, 2001), but the watch list only means they will be stopped if trying to enter or leave the US. There is another watch list that applies to domestic flights that some of their associates are on, but they are only placed on the international watch list (see April 24, 2000). Procedures are in place for law enforcement agencies to share watch list information with airlines and airports and such sharing is common, but the FAA and the airlines are not notified about this case, so the purchases raise no red flags. [Los Angeles Times, 9/20/2001; US Congress, 9/26/2002] An official later states that had the FAA been properly warned, “they should have been picked up in the reservation process.” [Washington Post, 10/2/2002] On September 4 and 5, 2001, an FBI agent will attempt to find Alhazmi and Almihdhar in the US, but will fail to conduct a simple credit card check that should have revealed these purchases (see September 4-5, 2001).
August 25-September 5, 2001: 9/11 Hijackers Spend Over $30,000 on 9/11 Tickets
All the 9/11 hijackers book their flights for September 11, 2001, using their apparent real names. The total cost of the tickets is in excess of $30,000: August 25: Khalid Almihdhar, who was watchlisted two days previously (see August 23, 2001), and Majed Moqed book tickets for American Airlines flight 77 using the AA.com website. They are collected from the American Airlines ticket counter at Baltimore Washington International Airport on September 5. The tickets were not mailed, because the shipping address did not match the credit card address. [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006, pp. 72, 74 ] August 26: Wail Alshehri buys a ticket for American Airlines flight 11 over the phone with his debit card.

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]
Late August-September 10, 2001: 9/11 Hijackers’ San Diego Associates Appear to Have Foreknowledge of Attacks
Associates of 9/11 hijackers Nawaf Alhazmi and Khalid Almihdhar in San Diego reportedly change their behavior and seem to be aware that “something big” is about to happen. But it is not clear how they would have obtained this information. The 9/11 Commission will suggest that there is evidence Alhazmi calls Mohdar Abdullah in late August (see (August 25, 2001)). Abdullah, a friend of these two hijackers in San Diego, may have been told some about the 9/11 plot back in 2000 and even invited to join in (see Early 2000 and June 10, 2000). He will later brag to someone in prison that he was told of the attack date three weeks in advance (see Early 2000). Both Abdullah and another former associate of the hijackers, Yazeed al-Salmi, suddenly become intent on marrying before 9/11. The 9/11 Commission will quote a witness saying al-Salmi told him, “I knew they were going to do something, that is why I got married.” In addition, employees at the Texaco station where Alhazmi worked (see Autumn 2000), including one named Iyad Kreiwesh, apparently expect that law enforcement authorities will visit them in the near future. Further, according to one witness, early on the morning of September 10, Abdullah, Osama Awadallah, Omar Bakarbashat, and others behave suspiciously at the gas station. The witness will say that after the group meets, Awadallah tells the others, “[I]t is finally going to happen” and they celebrate with high fives.

Late August 2001: Future Alleged Ricin Plotter Arrested in Netherlands, but Released
Mohammed Meguerba, a radical Islamist who will later confess to being part of a ricin plot under torture in Algeria (see September 18, 2002-January 3, 2003), is arrested at Schiphol Airport in Amsterdam, the Netherlands. He is stopped because police realize he is using a false passport, and is held for six months. He will make five asylum appeals, but they are all rejected. According to authors Sean O’Neill and Daniel McGrory, he is then “suddenly released” in February 2002, and travels to Paris, continuing to Italy and then Britain. [O’Neill and McGrory, 2006, pp. 243]
Between August 26 and September 9, 2001: 9/11 Hijacker Leaves Clues behind at Florida Motel
9/11 hijacker Marwan Alshehhi and a reportedly unidentified man stay at the Panther Motel in Deerfield Beach, Florida. During their stay, the manager, Richard Surma, observes that the two men have covered two paintings with towels, apparently for religious reasons, and are frequently visited by a third individual, who is also unidentified. When they leave on September 9, Surma finds several items left behind in a dumpster: a box cutter, aeronautical maps of the East Coast, martial arts books, and a tote bag from a flying school. [Boston Globe, 9/15/2001; Washington Post, 9/16/2001 ; Pittsburgh Post-Gazette, 9/30/2001; U.S.D.C Eastern District of Virginia, 7/31/2006, pp. 3 ] According to a timeline compiled by the Texas Service Center of the Immigration and Naturalization Service, Alshehhi is accompanied by fellow 9/11 hijacker Mohamed Atta when he checks out of the Panther Motel.
