9/11 hijacker Marwan Alshehhi takes a three-day trip to Las Vegas, and will later say he was followed on the trip. One of the hijackers’ associates, Ramzi bin al-Shibh, will later say in a 2002 interview that Alshehhi felt he was followed on a flight from New York to California by “security officers.” Bin al-Shibh will also say that fellow hijacker Ziad Jarrah felt he was followed on a similar flight (see June 7-10, 2001). 9/11 hijackers Nawaf Alhazmi and Khalid Almihdhar have also been concerned about possibly having been followed on a flight to the US (see January 15, 2000 and Mid-July 2000). [Fouda and Fielding, 2003, pp. 135] After arriving in New York from Florida and spending the night there, Alshehhi flies from New York to Las Vegas via San Francisco. He spends all but one night in Las Vegas at the St. Louis Manor hotel. He is clearly remembered by staff, who recall his face, manners, and that he was once visited by another man of Middle Eastern descent. He returns via the same route.

; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006, pp. 3, 19 ] Several other hijackers also travel to Vegas (see May 24-August 14, 2001).
Summer 2001: Some Hijackers Use Computers at Florida Public Library
According to Kathleen Hensman, a librarian at the Delray Beach, Florida public library, several hijackers use the library’s Internet computers during the summer months. She will remember them because, on one occasion, Marwan Alshehhi asks her about any good restaurants in the city. On another occasion, Mohand Alshehri and another individual keep staring at her while using a terminal. “They wanted to be aware of what I was doing,” she will say. [Washington Post, 9/17/2001 ; Pittsburgh Post-Gazette, 9/30/2001; New York Times, 11/23/2001]
June or July 2001: 9/11 Hijackers Atta and Alshehhi Plan Attacks from German University
Mohamed Atta, Marwan Alshehhi, and an unknown third person are seen in the ground-floor workshops of the architecture department at this time, according to at least two witnesses from the Hamburg university where Atta had studied. They are seen on at least two occasions with a white, three-foot scale model of the Pentagon. Between 60 and 80 slides of the Sears building in Chicago and the WTC are found to be missing from the technical library after 9/11. [Sunday Times (London), 2/3/2002] A Hamburg friend of Atta’s, Margritte Schroeder, will confirm that Atta is in Hamburg around this time, saying later in 2001, “I saw him here in early July and he was as nice as ever.” Other eyewitnesses see Atta and Alshehhi in Hamburg as well. But there is no record of Alshehhi leaving the US around this time, which suggests that he travels on a false passport for this trip. [Miller, Stone, and Mitchell, 2002, pp. 251, 290]
June 7, 2001: 9/11 Hijacker Alshehhi Possibly Enters Airplane Cockpit While Using Alias
Future 9/11 hijacker Marwan Alshehhi possibly enters an airline cockpit using an alias. According to a 2002 FBI document about the 9/11 attacks, a person matching Alshehhi’s photograph but using the name Matthew Cohen boards an American Airlines Boeing 767 flight from New York City to San Francisco. This person asks for and gets a tour of the cockpit just before the flight takes off. He talks to the pilot and asks questions, such as how high and fast the plane can fly, and how much fuel it can hold. The pilot will later recognize Alshehhi from a news photograph. [Federal Bureau of Investigation, 4/19/2002] Another of the 9/11 hijackers, Ziad Jarrah, flies from Baltimore to Los Angeles on this same day, and then drives to Las Vegas, so perhaps Alshehhi is meeting other hijackers in Las Vegas (see June 7-10, 2001).
June 11-12, 2001: Bank Refuses to Cash Check for ‘Suspicious’ 9/11 Hijacker, Fraud Alert Mysteriously Disappears One Day Later
Future 9/11 hijacker Marwan Alshehhi goes into a branch of the SunTrust Bank in Del Ray, Florida, apparently with fellow hijacker Hamza Alghamdi. Alshehhi and Mohamed Atta opened an account at SunTrust in July 2000, and Alshehhi tells the teller that he wants to cash a check for $2,818 and then use the money to purchase a cashier’s check to rent a nearby apartment. However, he arouses suspicion by presenting identification documents with different addresses and the bank personnel think the signature on the check does not match the signature on the file. The bank manager refuses to cash the check, and issues a 30-day internal alert to other SunTrust branches to watch out for possible fraud. But the next day, the alert is cancelled. After 9/11, SunTrust will be unable to figure out why this happened. A later review will show that Alshehhi does not cash any check at any branch around this time. Alghamdi also has a SunTrust bank account, but he also does not cash any check around this time. [9/11 Commission, 4/13/2004 ; 9/11 Commission, 8/21/2004, pp. 53, 140 ]
June 11-14, 2001: 9/11 Hijacker Seen in Hotel before He Apparently Enters US
9/11 hijacker Saeed Alghamdi is seen in a Florida hotel by the manager before he is said to enter the US. Although the 9/11 Commission will say he arrives in America on June 27 (see April 23-June 29, 2001), the manager of the Deluxe Inn in Dania, Florida, will tell the FBI that he stays there for these three nights from June 11-14 together with fellow hijackers Mohamed Atta, Ahmed Alnami, and Marwan Alshehhi, who completed the registration forms. [Federal Bureau of Investigation, 10/2001, pp. 157 ]
July 4-27, 2001: 9/11 Hijackers Spend Hundreds of Dollars on Porn and Sex Toys
9/11 hijackers Hamza Alghamdi and Marwan Alshehhi make two purchases of “pornographic video and sex toys” from a Florida store. They spend $252.17 on videos and toys at Video Outlet in Deerfield Beach on July 4, then return on July 27 and spend another $183.22. [Federal Bureau of Investigation, 10/2001, pp. 176, 178, 196, 198 ] These two and other hijackers are also reported to attend strip shows, watch porn, and use an escort service (see Before September 11, 2001 and September 7-11, 2001).
July 8-August 30, 2001: 9/11 Hijackers Purchase Knives
Several 9/11 hijackers purchase multi-use tools and small knives that “may actually have been used in the attacks.” according to the 9/11 Commission. [9/11 Commission, 7/24/2004, pp. 248-249] 
On July 8, Flight 11 hijacker Mohamed Atta buys two Victorinox Swiss Army knives at Zurich Airport, Switzerland, while on his way to Spain (see July 8-19, 2001). He possibly attempts to buy box cutters in Florida on August 27. On August 30, he buys a Leatherman multi-tool in Boynton Beach, Florida. [9/11 Commission, 7/24/2004, pp. 530; 9/11 Commission, 8/26/2004, pp. 4, 85] On August 13, Flight 175 hijackers Marwan Alshehhi, Fayez Ahmed Banihammad, and Hamza Alghamdi buy knives and multi-tools. Alshehhi buys a Cliphanger Viper and an Imperial Tradesman Dual Edge, both short-bladed knives. Banihammad buys a Stanley two-piece snap knife set, and Alghamdi buys a Leatherman Wave multi-tool. All purchases are made in the same city, though the 9/11 Commission does not say where this is. [9/11 Commission, 8/26/2004, pp. 17] On August 27, Flight 77 hijacker Nawaf Alhazmi buys Leatherman multi-tool knives. [9/11 Commission, 8/26/2004, pp. 27] Although it is unknown whether any of these knives and tools are used on 9/11, the 9/11 Commission will point out, “While FAA rules did not expressly prohibit knives with blades under four inches long, the airlines’ checkpoint operations guide (which was developed in cooperation with the FAA), explicitly permitted them.” [9/11 Commission, 7/24/2004, pp. 84] Regarding Flight 93, personal financial records do not reflect weapons being purchased by any of the hijackers. However, the FBI will reportedly recover “14 knives or portions of knives, including a box cutter,” at the crash site. [9/11 Commission, 7/24/2004, pp. 457; 9/11 Commission, 8/26/2004, pp. 35]
July 8-19, 2001: 9/11 Hijacker Atta Meets Associate Bin Al-Shibh and Possibly Others in Spain to Finalize Attack Plans
Some al-Qaeda operatives hold a meeting in northern Spain to finalize plans for the 9/11 attacks. Those allegedly present are listed below. The first two operatives listed are definitely present; it is less certain that the others are there: Future 9/11 hijacker Mohamed Atta. [El Mundo (Madrid), 9/30/2001] Ramzi bin al-Shibh, an associate of Atta from Hamburg, arrives in Spain on July 9, and stays until July 16. Spanish authorities are notified of his arrival in the country by German intelligence (see (Around July 9, 2001)). [New York Times, 5/1/2002] Some reports say that 9/11 hijacker Marwan Alshehhi attends, although if he does, he may use a false identity, as US immigration has no records of his departure or return. [El Mundo (Madrid), 9/30/2001; US Department of Justice, 5/20/2002] The Spanish newspaper La Vanguardia will later report that 9/11 hijackers Waleed and Wail Alshehri meet Atta on July 16. [Associated Press, 9/27/2001] However, there will be no mention of them attending the meeting in some other accounts. For example, their attendance will not be mentioned in the relevant section of the 9/11 Commission Report. [9/11 Commission, 7/24/2004, pp. 243-5] Amer el-Azizi. [Wall Street Journal, 4/7/2004; Associated Press, 1/23/2005] El-Azizi, who seems to have made preparations for the meeting, is under surveillance at this time, as Spanish authorities are listening in on his phone calls. [Wall Street Journal, 3/19/2004] Calls possibly related to the meeting’s organization were overheard (see Before July 8, 2001). [Los Angeles Times, 4/14/2004; Los Angeles Times, 4/29/2004] Spanish judge Baltasar Garzon will later indict el-Azizi for helping plan 9/11 and say that he assisted the plotters by arranging accommodation for them and acting as a courier. However, US officials will be less certain of his involvement. [Associated Press, 1/23/2005] His arrest shortly after 9/11 will be frustrated by Spanish intelligence (see October 2001 and Shortly After November 21, 2001) and he will go on to be involved in the 2004 Madrid bombings (see Before March 11, 2004 and 7:37-7:42 a.m., March 11, 2004). Barakat Yarkas, head of an al-Qaeda-linked cell in Spain. [New York Times, 11/20/2001; Los Angeles Times, 1/14/2003] Mohammed Belfatmi. Belfatmi is an associate of Yarkas, and lives near the hotels where Atta and bin al-Shibh stay. He will flee Europe just before 9/11 with Said Bahaji, a member of the al-Qaeda cell in Hamburg (see September 3-5, 2001). [Los Angeles Times, 1/14/2003; BBC Worldwide Monitoring, 12/2/2004] Mamoun Darkazanli and Mohammed Haydar Zammar, associates of Atta’s from Germany. Al Jazeera reporter Tayseer Allouni. Said Bahaji, a member of the al-Qaeda cell in Hamburg. According to Spanish investigators, Bahaji is with Atta the entire time, and they both stay at the Monica Hotel. [Fouda and Fielding, 2003, pp. 137] 9/11 mastermind Khalid Shaikh Mohammed (KSM). In 2002, Al Jazeera journalist Yosri Fouda will allegedly interview bin al-Shibh and KSM together before either of them are arrested (see April, June, or August 2002). Neither bin al-Shibh nor KSM will discuss any details of the meeting with Fouda, including who attended. KSM will neither confirm nor deny he was there. However, in a 2003 book, Fouda will claim that, according to Spanish investigators, the initial attendees are Atta, bin al-Shibh, Bahaji, and a fourth man who might be KSM. They are later joined by Alshehhi and two unnamed others. [Fouda and Fielding, 2003, pp. 137]
However, there is a parallel meeting in Granada, in the south of Spain, at this time, and Yarkas, Darkazanli, Zammar, and Allouni may only be at that meeting, and may not meet Atta and bin al-Shibh in person (see July 6, 2001 and Shortly After). [New York Times, 11/20/2001; Los Angeles Times, 1/14/2003] After being captured, bin al-Shibh will deny meeting anyone other than Atta while in Spain. [9/11 Commission, 7/24/2004, pp. 243-5] However, questions will be raised about the quality of information obtained from detainees due to the methods—including torture—used to extract it (see June 16, 2004). The movements of Atta and his associates in Spain are apparently mirrored by those of FBI agents John O’Neill and Mark Rossini (see July 5-16, 2001).
July 28-August 8, 2001: 9/11 Hijacker Alshehhi Takes Practice Flights, but Has Trouble with Basic Flying School Questions
9/11 hijacker Marwan Alshehhi pays for a few hours of ground and flying time at Kemper Aviation in Lantana, Florida. According to a document used as evidence at the Zacarias Moussaoui trial, on the first day, “Alshehhi could not answer basic questions on the written aviation test, which he needed an instructor’s assistance to complete.” Alshehhi returns on July 30 and August 8, when he rents a plane for approximately one hour. [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006, pp. 66 ] Alshehhi is accompanied by an unknown man on August 8. [Federal Bureau of Investigation, 10/2001 ] The FBI will visit the school on September 12, seizing all records of pilots from Saudi Arabia. Over a year later, the FBI will renew its interest in a Saudi, Turki al-Masri, who attended the school around the same time as Alshehhi, but the reason for the renewed interest is not known.
