The fire alarm system in World Trade Center Building 7 is placed on “test condition,” which causes any alarms to be ignored, every morning in the seven days preceding September 11. [National Institute of Standards and Technology, 6/2004, pp. 94; National Institute of Standards and Technology, 9/2005, pp. 67; National Institute of Standards and Technology, 11/2008, pp. 69] WTC 7 is a 47-story office building located 370 feet north of the North Tower. [National Institute of Standards and Technology, 8/21/2008; National Institute of Standards and Technology, 11/2008, pp. 2] Its alarm system is placed on test condition “every morning at about the same time” in the seven days before September 11, according to a report by the National Institute of Standards and Technology. Since it will be in test condition on September 11 for a period of eight hours, starting at 6:47 a.m. (see 6:47 a.m.-2:47 p.m. September 11, 2001), the system is presumably put on test condition at a similar time and also for eight hours in the seven days before then. At the end of the eight-hour period, the alarm system automatically returns to normal monitoring.
Alarms Are Ignored During Testing – Test condition is usually requested when maintenance or testing is being carried out on the alarm system. While the system is in this mode, any alarms that are received are considered to be the result of the maintenance or testing and are therefore ignored. Furthermore, while the system is in test condition, any alarm signals do not appear on the operator’s display. However, records of the alarm are still recorded in the system’s history file. [National Institute of Standards and Technology, 9/2005, pp. 66; National Institute of Standards and Technology, 11/2008, pp. 68-69]
Alarm System Is Monitored Away from the WTC – The alarm system in WTC 7 records information at just one location within the building: the fire command station in the third-floor lobby. It is monitored at a location away from the WTC site by AFA Protective Systems, a New York-based company that designs, installs, and services fire alarm systems. [National Institute of Standards and Technology, 6/2004, pp. 93; National Institute of Standards and Technology, 4/5/2005
; US Immigration and Customs Enforcement, 8/4/2017] AFA Protective Systems usually places the alarm system in WTC 7 on test condition in response to a request from the building manager. [National Institute of Standards and Technology, 11/2008, pp. 69] It is unclear who the building manager is, although Mike Catalano, chief engineer for Salomon Smith Barney at WTC 7, will later say the building manager is a man called Ed Campbell. [International Union of Operating Engineers, 2003, pp. 27; 9/11 Commission, 1/16/2004
] Records indicate that the alarm system in WTC 7 is often placed on test condition. [National Institute of Standards and Technology, 11/2008, pp. 69]
September 4, 2001: FBI Agent Fails to Search for 9/11 Hijacker Data Present in Private Database
Robert Fuller, an inexperienced FBI agent, searches for hijackers Nawaf Alhazmi and Khalid Almihdhar in the US on this day (see September 4-5, 2001). He claims that his search includes querying the ChoicePoint database. ChoicePoint is one of several companies maintaining commerical databases on personal information about US citizens. The FBI has a contract to access the ChoicePoint database, but none of the others. Fuller supposedly does not find any record on either Alhazmi or Almihdhar. He suggests this is because of variations in the spelling of names. However, the chairman of ChoicePoint will later confirm that although the database did have information on the hijackers before 9/11, the FBI did not ask to search the database until shortly after 9/11. The 9/11 Commission will conclude the database was not searched, and notes, “Searches of readily available databases could have unearthed” their California drivers’ licenses, car registrations, and telephone listings. Thomas Pickard, acting FBI Director at the time this search is made, will later falsely claim in public testimony before the 9/11 Commission that the FBI was not allowed to search the ChoicePoint database before 9/11. [9/11 Commission, 7/24/2004, pp. 539; US Department of Justice, 11/2004; New York Observer, 11/28/2004] An FBI timeline put together shortly after 9/11 will mention that Alhazmi’s 2000 San Diego phone number was in the ChoicePoint database. The exact spelling for the phone number listing was Nawaf M. Al Hazmi. [Federal Bureau of Investigation, 10/2001, pp. 59

September 4, 2001: Army Officers at Pentagon Planning Exercise for Days after 9/11, Based on Plane Hitting WTC Scenario
Army officers plan an exercise for the Army’s Crisis Action Team (CAT) at the Pentagon based around the scenario of a plane crashing into the World Trade Center, which they intend to run during the week following September 11. The officer who is in charge of preparing the exercise is Major General Peter Chiarelli. Chiarelli took over as the Army’s director of operations, readiness, and mobilization around early to mid-August this year. In this position, he is in charge of current operations in the Army Operations Center (AOC)—the Army’s “command and control center,” according to Chiarelli—located in the basement of the Pentagon. [US Army Center of Military History, 2/5/2002; Soldiers, 9/2004; Army News Service, 8/5/2008]
New Army Director Plans to Run Crisis Team Exercise – Chiarelli will later recall how the plans for the exercise come about. He will tell an interviewer that in some of the briefings he received when learning about his new post, he was told “that the Crisis Action Team had not stood up, except for an exercise, in about 10 years in any great role.” Therefore, after beginning in the post, he “planned to do an exercise for the Crisis Action Team.” Around the same time, the Personnel Contingency Cell, which is one of the CAT’s support teams, has been directed to put together a new mass casualty standard operating procedure (SOP) for the Army.
New Operating Procedure Has Scenario of Plane Hitting WTC – About a week before 9/11, Raymond Robinson Jr., the chief of operations for the Army’s deputy chief of staff for personnel, and two other officers come to brief Chiarelli on their new SOP. Chiarelli will recall, “The real amazing thing of that SOP is that the scenario was an aircraft crashing into the World Trade Center.” Chiarelli tells the officers, “Hey, not only is this a good SOP and a good plan, but at the same time, to really make this good, what we need to do is exercise it.” Therefore, as he will later recall, “[W]e decided to integrate a scenario like that into my first CAT exercise.” The scenario of a plane crashing into the WTC would be used “to drive this exercise” that Chiarelli is planning to run. Chiarelli will not say what type of aircraft is envisaged hitting the WTC in the scenario, nor specify whether it would have been a hijacked plane or one that crashed into the WTC accidentally.
Exercise Scheduled for September 17 or September 13 – The exact date on which the CAT exercise is set to take place is unclear. Chiarelli will say he has his “folks design it for me on the 17th of September.” [US Army Center of Military History, 2/5/2002; Lofgren, 2011, pp. 95-97] However, Army Center of Military History historian Stephen Lofgren will mention, while interviewing Chiarelli’s deputy, Brigadier General Clyde Vaughn, that the exercise is scheduled to take place “a couple of days” after September 11, meaning September 13. [US Army Center of Military History, 2/12/2002] The exercise is presumably canceled as a result of the 9/11 attacks. The CAT, whose members are set to participate in it, will be activated on September 11 in response to the attacks on the WTC, so as to “respond to the contingency in New York if requested by state and local officials” (see (Shortly After 9:03 a.m.) September 11, 2001). [Goldberg et al., 2007, pp. 134]
September 4, 2001: Army Restricts Access to Fort Belvoir
The US Army sharply restricts public access to Fort Belvoir, one of its installations about 12 miles south of the Pentagon. After being an open post for over 25 years, Belvoir has now erected barriers across many of the roads leading into it, leaving only six guarded gates as points of entry and exit. Twenty access points are being permanently closed. Visitors must now register their vehicles at a visitor’s center or get a day pass to enter the base. [MDW News Service, 7/2001; Washington Post, 8/15/2001] The access restrictions will allow commanders to know who is entering the base 24 hours a day and adjust security measures immediately if needed. [MDW News Service, 8/3/2001] All other Military District of Washington (MDW) installations are implementing similar changes, due to Army concerns about terrorism (see August 15, 2001). Fort Belvoir has about 20,000 workers and is home to many different agencies, including the US Army Intelligence and Security Command (INSCOM), plus the headquarters of the Defense Logistics Agency and the Defense Technical Information Service. [Military District of Washington, 8/2000; Washington Post, 8/15/2001; GlobalSecurity (.org), 10/21/2001] Occupying over 500 acres at Belvoir is Davison Army Airfield. The 12th Aviation Battalion, which is MDW’s aviation-support unit, is stationed at Davison. This operates UH1 “Huey” and UH60 Black Hawk helicopters in support of training and “contingencies” for various MDW units. [Military District of Washington, 8/2000; GlobalSecurity (.org), 1/5/2002] The Washington Post has reported, “Fort Belvoir will be holding exercises the next two Tuesdays to test the changes” in access to the base. [Washington Post, 8/15/2001] This will therefore include September 11 (a Tuesday). Other reports will confirm an antiterrorism exercise being conducted at Belvoir on 9/11 (see 8:30 a.m. September 11, 2001).
September 4, 2001: Counterterrorism Chief Clarke Warns that Hundreds of Americans Could Die in an Al-Qaeda Attack
White House counterterrorism chief Richard Clarke sends a memo to National Security Adviser Condoleezza Rice in which he warns that hundreds of Americans could die in an attack by al-Qaeda and complains that the Bush administration is not doing enough to combat the threat posed by the terrorist network. [9/11 Commission, 3/24/2004; Washington Post, 3/25/2004] The National Security Council’s principals committee—a group of senior officials who advise the president on issues of national security policy—is set to meet today to discuss al-Qaeda. Before the meeting takes place, Clarke sends a memo to Rice in which he criticizes US counterterrorism efforts.
Al-Qaeda Could Kill ‘Hundreds of Americans’ – The “real question” before the members of the principals committee, Clarke writes in the memo, is, “[A]re we serious about dealing with the al-Qaeda threat?” He suggests: “Decision makers should imagine themselves on a future day when the [White House Counterterrorism Security Group] has not succeeded in stopping al-Qaeda attacks and hundreds of Americans lay dead in several countries, including the US. What would those decision makers wish that they had done earlier?” “That future day could happen at any time,” he adds.
Clarke Complains about the Lack of Response to the USS Cole Bombing – Clarke criticizes the US military for failing to respond to the attack on the USS Cole in Yemen, in October 2000 (see October 12, 2000). “Many in al-Qaeda and the Taliban may have drawn the wrong lesson from the Cole: that they can kill Americans without there being a US response, without there being a price,” he writes. He states that he cannot understand “why we continue to allow the existence of large-scale al-Qaeda bases where we know people are being trained to kill Americans.”
Clarke Warns of a Possible ‘Big Attack, with Lots of Casualties’ – Clarke complains that without adequate funding: “You are left with a modest effort to swat flies, to try to prevent specific al-Qaeda attacks by using [intelligence] to detect them, and friendly governments’ police and intelligence officers to stop them. You are left waiting for the big attack, with lots of casualties, after which some major US retaliation will be in order.” [9/11 Commission, 7/24/2004, pp. 212-213]
Rice Later Says Memo Is ‘Not a Warning about September 11th’ – Rice will later say of Clarke’s memo: “It would not be appropriate or correct to characterize what Dick [Clarke] wrote to me on September 4th as a warning of an impending attack. What he was doing was, I think, trying to buck me up so that when I went into this principals meeting, I was sufficiently on guard against the kind of bureaucratic inertia that he had fought all of his life.” The memo, she will say, “was a warning to me not to get dragged down by the bureaucracy, not a warning about September 11th.” [9/11 Commission, 4/8/2004] The principals committee’s meeting today is the committee’s first meeting on al-Qaeda issues. [9/11 Commission, 3/24/2004; 9/11 Commission, 7/24/2004, pp. 212] Clarke had “urgently” called for such a meeting back in January this year (see January 25, 2001). [Clarke, 2004, pp. 237]
September 4, 2001: Cabinet-Rank Advisers Discuss Terrorism, Approve Revised Version of Clarke’s Eight Month-Old-Plan
President Bush’s cabinet-rank advisers discuss terrorism for the second of only two times before 9/11. [Washington Post, 5/17/2002] National Security Adviser Rice chairs the meeting; neither President Bush nor Vice President Cheney attends. Counterterrorism “tsar” Richard Clarke later says that in this meeting, he and CIA Director Tenet speak passionately about the al-Qaeda threat. No one disagrees that the threat is serious. Secretary of State Powell outlines a plan to put pressure on Pakistan to stop supporting al-Qaeda. Defense Secretary Rumsfeld appears to be more interested in Iraq. The only debate is over whether to fly the armed Predator drone over Afghanistan to attack al-Qaeda (see September 4, 2001). [Clarke, 2004, pp. 237-38] Clarke’s earlier plans to “roll back” al-Qaeda first submitted on January 25, 2001 (see January 25, 2001) have been discussed and honed in many meetings and are now presented as a formal National Security Presidential Directive. The directive is “apparently” approved, though the process of turning it into official policy is still not done. [9/11 Commission, 3/24/2004] There is later disagreement over just how different the directive presented is from Clarke’s earlier plans. For instance, some claim the directive aims not just to “roll back” al-Qaeda, but also to “eliminate” it altogether. [Time, 8/12/2002] However, Clarke notes that even though he wanted to use the word “eliminate,” the approved directive merely aims to “significantly erode” al-Qaeda. The word “eliminate” is only added after 9/11. [Washington Post, 3/25/2004] Clarke will later say that the plan adopted “on Sept. 4 is basically… what I proposed on Jan. 25. And so the time in between was wasted.” [ABC News, 4/8/2004] The Washington Post will similarly note that the directive approved on this day “did not differ substantially from Clinton’s policy.” [Washington Post, 3/27/2004] Time magazine later comments, “The fight against terrorism was one of the casualties of the transition, as Washington spent eight months going over and over a document whose outline had long been clear.” [Time, 8/12/2002] The primary change from Clarke’s original draft is that the approved plan calls for more direct financial and logistical support to the Northern Alliance and other anti-Taliban groups. The plan also calls for drafting plans for possible US military involvement, “but those differences were largely theoretical; administration officials told the [9/11 Commission’s] investigators that the plan’s overall timeline was at least three years, and it did not include firm deadlines, military plans, or significant funding at the time of the September 11, 2001, attacks.” [Washington Post, 3/27/2004; Reuters, 4/2/2004]
September 4, 2001: Debate Heats Up Over Using Armed Predator Drone Against Bin Laden; Decision Again Delayed
Attendees to an important cabinet-level meeting on terrorism have a heated debate over what to do with the armed Predator drone, which has been ready for use over Afghanistan since June 2001 (see Early June-September 10, 2001). Counterterrorism “tsar” Richard Clarke has been repeatedly pushing for the use of the Predator over Afghanistan (in either armed or unarmed versions), and he again argues for its immediate use. Everyone agrees that the armed Predator capability is needed, but there are disputes over who will manage and/or pay for it. CIA Director Tenet says his agency will operate the armed Predator “over my dead body.” [Washington Post, 10/2/2002] Clarke recalls, “The Air Force said it wasn’t their job to fly planes to collect intelligence. No one around the table seemed to have a can-do attitude. Everyone seemed to have an excuse.” [New Yorker, 7/28/2003] National Security Adviser Rice concludes that the armed Predator is not ready (even though it had been proven in tests during the summer), but she also presses Tenet to reconsider his opposition to immediately resume reconnaissance flights, suspended since September the year before. After the meeting, Tenet agrees to proceed with such flights. [9/11 Commission, 3/24/2004; 9/11 Commission, 3/24/2004] The armed Predator is activated just days after 9/11, showing that it was ready to be used after all. [Associated Press, 6/25/2003]
September 4, 2001: Mueller Takes Over as FBI Director; Criticized for BCCI Investigation
Robert Mueller assumes the job of FBI Director. He had been nominated for the job in July 2001 after Louis Freeh’s unexpected and sudden resignation (see May 1, 2001). Thomas Pickard was interim director for three months. Mueller held a variety of jobs in the Justice Department for over a decade prior to his nomination. Most notably, he led Justice Department investigations into the 1991 collapse of the Bank of Credit and Commerce International (BCCI) (see July 5, 1991) and the 1988 bombing of Pan-Am Flight 103 over Lockerbie, Scotland. [BBC, 7/5/2001; CNN, 9/5/2001] Mueller was heavily criticized for his role in the BCCI investigation (see February 1988-December 1992). For instance, a bipartisan Congressional BCCI investigation led by Senators John Kerry (D-MA) and Hank Brown (R-CO) stated, “Unfortunately, as time has passed it has become increasingly clear that the Justice Department did indeed make critical errors in its handling of BCCI… and moreover masked inactivity in prosecuting and investigating the bank by advising critics that matters pertaining to BCCI were ‘under investigation,’ when in fact they were not” and also “[hindered] other legitimate investigative efforts, and [failed] to admit that it had made any of these mistakes.” [US Congress, 12/1992] Mueller himself noted in 1991 that there was an “appearance of, one, foot-dragging; two, perhaps a cover-up,” but denied the cover-up claims. A Wall Street Journal editorial notes that “Even George W. Bush bumped up against the outer fringes of the BCCI crowd during his tenure with Harken Energy and in his friendship with Texas entrepreneur James Bath,” and opines, “On general principles, our view is that it would be a mistake to appoint as FBI head anyone who had any role in the failed BCCI probe. Too many important questions remain unanswered…” [Wall Street Journal, 6/26/2001]
September 4, 2001: Secret Embedded Messages Help Show Milan Al-Qaeda Have 9/11 Foreknowledge
At least one member of the al-Qaeda cell in Milan, Italy, apparently uses steganography, a method of encoding messages within computerized photographs. In Milan’s Via Quaranta mosque in Milan, frequented by Egyptian al-Qaeda operative Mahmoud Es Sayed, pictures of the World Trade Center that have steganographic messages in them are saved on a computer. A number of other pictures of world leaders and pornography are also manipulated in a similar manner. These pictures will not be discovered until months after 9/11, but they help suggest that some in the Milan cell had foreknowledge of the 9/11 plot. Es Sayed had been wiretapped on previous occasions, and was heard making comments suggesting he had such foreknowledge (see August 12, 2000)
(see January 24, 2001). His current whereabouts are unknown. [ABC News, 5/8/2003]
September 4, 2001: FBI Dispatches Vague Message to US Intelligence Community About Moussaoui Investigation
FBI headquarters dispatches a memo to the entire US intelligence community summarizing what has been learned about Zacarias Moussaoui. The memo, written by Mike Maltbie, an agent in the FBI’s Radical Fundamentalist Unit (RFU), reports that the FBI has become suspicious of Moussaoui because he took flight simulation training for a 747 jet, a course normally taken by airline pilots. Moussaoui, who has no flying experience, paid cash for the training, the memo also notes. It also says that Moussaoui has radical Islamic fundamentalist beliefs and has been linked to Chechen militants. However, the memo does not include a threat assessment or indicate that some FBI investigators believe Moussaoui is part of a yet unknown plot to hijack an airplane and use it in a terrorist attack. As a later congressional inquiry will report, the memo fails to “recommend that the addressees take any action or look for any additional indicators of a terrorist attack, nor [does] it provide any analysis of a possible hijacking threat or provide any specific warnings.” [US Congress, 9/24/2002; US Department of Justice, 11/2004, pp. 175-6
] Several days earlier, Maltbie blocked the release of a memo from the FBI’s Minneapolis field office that was addressed to the FAA and did contain a threat assessment (see August 29-September 4, 2001). When the FAA receives the FBI memo, it decides not to issue a security alert to the nation’s airports in response. An FAA representative later explains to the New York Post, “[Moussaoui] was in jail and there was no evidence he was connected to other people.” [New York Post, 5/21/2002] The FBI memo contrasts sharply with an internal CIA warning sent out on August 24. That memo, which was based on less information, warned that Moussaoui might be “involved in a larger plot to target airlines traveling from Europe to the US” (see August 24, 2001). [US Congress, 9/18/2002] It turns out that prior to this time, al-Qaeda operative Ahmed Ressam had started cooperating with investigators. He had trained with Moussaoui in Afghanistan and will willingly share this information after 9/11. The FBI dispatch, with its notable lack of urgency and details, fails to prompt the agents in Seattle holding Ressam to question him about Moussaoui. Had the connection between these two men been learned before 9/11, presumably the search warrant for Moussaoui would have been approved and the 9/11 plot might have unraveled (see Late August-Early September 2001).
