bullet Two of Mohamed Atta’s bags are found on 9/11. They contain a handheld electronic flight computer, a simulator procedures manual for Boeing 757 and 767 aircraft, two videotapes relating to “air tours” of the Boeing 757 and 747 aircraft, a slide-rule flight calculator, a copy of the Koran, Atta’s passport, his will, his international driver’s license, a religious cassette tape, airline uniforms, a letter of recommendation, “education related documentation” and a note (see September 28, 2001) to other hijackers on how to mentally prepare for the hijacking. [Sydney Morning Herald, 9/15/2001; Boston Globe, 9/18/2001; Independent, 9/29/2001; Associated Press, 10/5/2001] Author Terry McDermott will later comment, “Atta’s bag contained nearly every important document in his life… If you wanted to leave a roadmap for investigators to follow, the suitcase was a pretty good place to start.” [McDermott, 2005, pp. 306]
bullet Marwan Alshehhi’s rental car is discovered at Boston’s Logan Airport containing an Arabic language flight manual, a pass giving access to restricted areas at the airport, documents containing a name on the passenger list of one of the flights, and the names of other suspects. The name of the flight school where Atta and Alshehhi studied, Huffman Aviation, is also found in the car. [Los Angeles Times, 9/13/2001]
bullet A car registered to Nawaf Alhazmi is found at Washington’s Dulles Airport on September 12. This is the same car he bought in San Diego in early 2000 (see March 25, 2000). Inside is a copy of Atta’s letter to the other hijackers, a cashier’s check made out to a flight school in Phoenix, four drawings of the cockpit of a 757 jet, a box cutter-type knife, maps of Washington and New York, and a page with notes and phone numbers. [Arizona Daily Star, 9/28/2001; Cox News Service, 10/21/2001; Die Zeit (Hamburg), 10/1/2002] The name and phone number of Osama Awadallah, a friend of Alhazmi and Khalid Almihdhar in San Diego, is also found on a scrap of paper in the car (see September 12, 2001 and After). [CNN, 2/1/2002]
bullet A rental car is found in an airport parking lot in Portland, Maine. Investigators are able to collect fingerprints and hair samples for DNA analysis. [Portland Press Herald, 10/14/2001]
bullet A Boston hotel room contains airplane and train schedules. [Sydney Morning Herald, 9/15/2001]
bullet FBI agents carry out numerous garbage bags of evidence from a Florida apartment where Saeed Alghamdi lived. [CNN, 9/17/2001]
bullet Two days before 9/11, a hotel owner in Deerfield Beach, Florida, finds a box cutter left in a hotel room used by Marwan Alshehhi and two unidentified men. The owner checks the nearby trash and finds a duffel bag containing Boeing 757 manuals, three illustrated martial arts books, an 8-inch stack of East Coast flight maps, a three-ring binder full of handwritten notes, an English-German dictionary, an airplane fuel tester, and a protractor. The FBI seizes all the items when they are notified on September 12 (except the binder of notes, which the owner apparently threw away). [Miami Herald, 9/16/2001; Associated Press, 9/16/2001]
bullet In an apartment rented by Ziad Jarrah and Ahmed Alhaznawi, the FBI finds a notebook, videotape, and photocopies of their passports. [Miami Herald, 9/15/2001]
bullet In a bar the night before 9/11, after making predictions of a attack on America the next day, the hijackers leave a business card and a copy of the Koran at the bar. The FBI also recovers the credit card receipts from when they paid for their drinks and lap dances. [Associated Press, 9/14/2001]
bullet A September 13 security sweep of Boston airport’s parking garage uncovers items left behind by the hijackers: a box cutter, a pamphlet written in Arabic, and a credit card. [Washington Post, 9/16/2001]
bullet A few hours after the attacks, suicide notes that some of the hijackers wrote to their parents are found in New York. Credit card receipts showing that some of the hijackers paid for flight training in the US are also found. [Los Angeles Times, 9/13/2001]
bullet A FedEx bill is found in a trash can at the Comfort Inn in Portland, Maine, where Atta stayed the night before 9/11. The bill leads to Dubai, United Arab Emirates, allowing investigators to determine much of the funding for 9/11. [Newsweek, 11/11/2001; London Times, 12/1/2001]
bullet A bag hijackers Alhazmi and Almihdhar left at a mosque in Laurel, Maryland, is found on September 12. The bag contains flight logs and even receipts from flight schools from San Diego the year before (see September 9, 2001).
bullet On 9/11, in a Days Inn hotel room in Newark, New Jersey, investigators find used plane tickets for Saeed Alghamdi, Ahmed Alhaznawi, Ziad Jarrah, and Ahmed Alnami. The tickets are all from a Spirit Continental Airlines flight from Ft. Lauderdale, Florida, to Newark on September 7. Also, flight manuals for Boeing 757 and 767 airplanes are found in English and Arabic. [Investigative Services Division, FBI Headquarters, 4/19/2002]
The hijackers past whereabouts can even be tracked by their pizza purchases. An expert points out: “Most people pay cash for pizza. These [hijackers] paid with a credit card. That was an odd thing.” [San Diego Union-Tribune, 9/3/2002] “In the end, they left a curiously obvious trail—from martial arts manuals, maps, a Koran, Internet and credit card fingerprints. Maybe they were sloppy, maybe they did not care, maybe it was a gesture of contempt of a culture they considered weak and corrupt.” [Miami Herald, 9/22/2001] The New Yorker quotes a former high-level intelligence official as saying: “Whatever trail was left was left deliberately—for the FBI to chase” (see Late September 2001).
