The FBI’s Critical Incident Response Group (CIRG) goes to California for a week of training and is therefore stranded away from Washington, DC, when it is required to help in the response to the 9/11 terrorist attacks. [USA Today, 9/11/2001; Darling, 2010, pp. 75] The CIRG is “the unit that coordinates the FBI’s rapid response to crisis incidents, including terrorist attacks,” according to Major Robert Darling of the White House Military Office. Its members arrive in San Francisco this evening to participate in a week of special weapons and tactics (SWAT)-related field training. [Darling, 2010, pp. 74-75] While the 9/11 attacks are underway, NBC News will report that the FBI is in a state of “chaos,” partly because of the CIRG being stranded in California (see 10:03 a.m. September 11, 2001). [NBC 4, 9/11/2001] On the afternoon of September 11, the White House will arrange for the CIRG to return to Washington as a matter of priority (see (3:50 p.m.) September 11, 2001), and the unit’s members will be flown back later that day (see Late Afternoon September 11, 2001). [Darling, 2010, pp. 73-76]
Unit Created to Respond to Terrorist Incidents – The CIRG would be a valuable resource for responding to the 9/11 attacks. The unit was established in 1994 “to give the FBI the ability to respond with the tactical and investigative expertise needed in a major terrorist incident,” according to the Congressional Research Service. It has crisis managers, hostage negotiators, behavioral scientists, surveillance assets, and agents that it can utilize. [United States General Accounting Office, 9/1997, pp. 40 
; Brake, 4/19/2001, pp. 9-10 ] The CIRG also has a “seven-step approach” it follows, which uses “active listening” to defuse a crisis. According to the Indian Express, “by showing support and empathy, [CIRG] negotiators often can talk a hijacker into surrendering largely by listening.” [Law Enforcement Bulletin, 8/1997; Indian Express, 12/29/1999]
Hostage Rescue Team Serves as Domestic Counterterrorism Unit – The tactical centerpiece of the CIRG is the Hostage Rescue Team (HRT), a full-time team headquartered in Quantico, Virginia, that is able to deploy to any location within four hours of notification. Its skills include hostage rescue tactics, precision shooting, and tactical site surveys. [United States General Accounting Office, 9/1997, pp. 40 ; Brake, 4/19/2001, pp. 10 ] The HRT was created to give civilian law enforcement agencies a counterterrorist community comparable to that which exists in the military. Many of its members have a military background. [Training and Simulation Journal, 2/2009] According to Darling, the HRT is ”the domestic counterterrorism unit, offering a tactical resolution option in hostage and high-risk law enforcement situations.” [Darling, 2010, pp. 7]
September 10, 2001: NSA Monitors Call as 9/11 Mastermind KSM Gives 9/11 Hijacker Atta Final Approval to Launch Attacks
9/11 hijacker Mohamed Atta calls 9/11 mastermind Khalid Shaikh Mohammed (KSM) in Afghanistan. KSM gives final approval to Atta to launch the attacks. The specifics of the conversation haven’t been released. [Independent, 9/15/2002] Unnamed intelligence officials later tell Knight Ridder Newspapers that the call is monitored by the NSA, but only translated after the 9/11 attacks. KSM, “using coded language, [gives] Atta final approval” for the attacks. [Knight Ridder, 9/9/2002] NSA monitored other calls between KSM and Atta in the summer of 2001 but did not share the information about this with other agencies (see Summer 2001). Additionally, it will later be revealed that an FBI squad built an antenna in the Indian Ocean some time before 9/11 with the specific purpose of listening in on KSM’s phone calls, so they may have learned about this call to Atta on their own (see Before September 11, 2001).
September 10, 2001: Alleged CIA Informant Warns Syrian Government about 9/11 Attacks; Syria Apparently Fails to Pass on Warning
In his 2007 book At the Center of the Storm, former CIA Director George Tenet will write that on September 10, 2001, “a source we were jointly running with a Middle Eastern country went to see his foreign handler and basically told him that something big was about to go down. The handler dismissed him.” Tenet claims the warning was “frightening but without specificity.” [Tenet, 2007, pp. 160] While Tenet will not mention the name of the source, his description perfectly matches a Syrian-born militant named Luai Sakra. Sakra will be arrested in Turkey in 2005 (see July 30, 2005) and reportedly will tell interrogators after his arrest, “I was one of the people who knew the 9/11 perpetrators, and I knew the plans and times beforehand.” He claims to have provided the pilots with passports and money (see September 2000-July 24, 2001). Der Spiegel will report, “Western investigators accept Sakra’s claims, by and large, since they coincide with known facts. On September 10, 2001, he tipped off the Syrian secret service… that terrorist attacks were about to occur in the United States. The evidently well-informed al-Qaeda insider even named buildings as targets, and airplanes as weapons. The Syrians passed on this information to the CIA—but only after the attacks.” [Der Spiegel (Hamburg), 8/24/2005] In 2007, Sakra will also claim to have trained some of the 9/11 hijackers in Turkey starting in late 1999 (see Late 1999-2000). If Tenet is referring to Sakra, then it appears Sakra did develop a relationship with the CIA that continued at least through 9/11 (see 2000).
Shortly Before September 11, 2001: Pilot of Flight 93 Not Originally Scheduled for that Flight, but Trades Shifts
Pilot Jason Dahl, who will be at the controls of United Airlines Flight 93—the fourth hijacked aircraft—on 9/11, is not originally scheduled for that flight, but wants to get in extra hours so he can take time off work for his fifth wedding anniversary on September 14. [Pittsburgh Post-Gazette, 10/28/2001; MSNBC, 9/11/2006] Therefore, some time shortly before 9/11, he trades a trip later in September in order to fly September 11. [Denver Post, 12/16/2001; Longman, 2002, pp. 1] Yet the week before September 11, he sends out an e-mail seeking another pilot to take his place, so he can have that day with his family. [Rocky Mountain News, 9/12/2001; New York Times, 9/15/2001; San Francisco Chronicle, 9/17/2001] Pilots on two of the other aircraft hijacked on 9/11 are also not originally scheduled to fly that day, but are booked onto those planes shortly before September 11 (see September 10, 2001, Shortly Before September 11, 2001, and Shortly Before September 11, 2001).
September 10, 2001: NSA Intercepts: ‘The Match Begins Tomorrow’ and ‘Tomorrow Is Zero Hour’
At least two messages in Arabic are intercepted by the NSA. One states, “The match is about to begin” and the other states, “Tomorrow is zero hour.” Later reports translate the first message as, “The match begins tomorrow.” [Reuters, 9/9/2002] The messages were sent between someone in Saudi Arabia and someone in Afghanistan. The NSA will claim that they are not translated until September 12, and that even if they had been translated in time, “they gave no clues that authorities could have acted on.” [ABC News, 6/7/2002; Reuters, 6/19/2002] Chairman of the Senate Intelligence Committee Bob Graham will later confirm that the messages were from al-Qaeda sources—a location or phone number—that made them a high priority, but that they were not from bin Laden or one of his top commanders. [Graham and Nussbaum, 2004, pp. 139] On the morning of September 12, 2001, the CIA will tell President Bush that a recently intercepted message from al-Qaeda leader Abu Zubaida referred to the 9/11 attacks as “zero hour,” but it is not clear if this is the same message or a different message (see September 12, 2001). These messages turn out to be only two of about 30 pre-9/11 communications from suspected al-Qaeda operatives or other militants referring to an imminent event. An anonymous official will say of these messages, including the “Tomorrow is zero hour” message: “You can’t dismiss any of them, but it does not tell you tomorrow is the day.” [Reuters, 9/9/2002] There will be a later attempt to explain the messages away by suggesting they referred to the killing of Afghan opposition leader Ahmed Shah Massoud the day before (see September 9, 2001). [Reuters, 10/17/2002]
September 10, 2001: Anti-Terrorism Meeting at WTC on 9/11 Is Canceled
Silverstein Properties, Larry Silverstein’s company which took over the lease of the WTC weeks earlier (see July 24, 2001), has a meeting planned for the morning of 9/11 in it’s temporary offices on the 88th floor of the WTC North Tower, along with Port Authority officials. It is to discuss what to do in the event of a terrorist attack. However, this evening the meeting is canceled because one participant cannot attend. [New York Times, 9/12/2001; Ha’aretz, 11/21/2001] Of Silverstein Properties’ 160 staff, 54 are in the North Tower when it is hit, and four of them die. [Globe and Mail, 9/7/2002]
Before September 11, 2001: NEADS Staff Briefed on Possibility of Plane Hitting WTC
Staff members at NORAD’s Northeast Air Defense Sector (NEADS) are apparently briefed on the possibility of terrorists deliberately crashing a plane into the World Trade Center. According to author Lynn Spencer, when Trey Murphy—a former US Marine who is now a weapons controller at NEADS—first sees the television footage on September 11 showing that a plane has hit the WTC, the news will bring to mind one of his briefings: “What if a terrorist flies an airplane with a weapon of mass destruction into the World Trade Center? It had always been one of the military’s big fears.… [T]he image on the [television] screen certainly reminded him of his briefing.” [Spencer, 2008, pp. 179] It is also later reported that, in the two years prior to 9/11, NORAD conducts exercises simulating terrorists crashing hijacked aircraft into targets that include the WTC (see Between September 1999 and September 10, 2001). [USA Today, 4/18/2004] Yet, in May 2002, National Security Adviser Condoleezza Rice will claim, “I don’t think anybody could have predicted that these people would take an airplane and slam it into the World Trade Center… that they would try to use an airplane as a missile, a hijacked airplane as a missile” (see May 16, 2002). [White House, 5/16/2002] And in 2004, NORAD commander General Ralph Eberhart will say, “Regrettably, the tragic events of 9/11 were never anticipated or exercised.” [USA Today, 4/18/2004]
September 10, 2001: Training Exercise Scenario at NORAD’s Southeast Sector Involves Cubans Hijacking Plane, Wanting to Go to New York
Personnel at NORAD’s Southeast Air Defense Sector (SEADS) at Tyndall Air Force Base, Florida, practice for the scenario of an aircraft being hijacked by Cuban asylum seekers. The scenario is part of the annual NORAD training exercise, Vigilant Guardian. [9/11 Commission, 2004; Spencer, 2008, pp. 3] In the scenario, the fictitious hijackers take over an Ilyushin IL-62 jet airliner that took off from Havana, Cuba. The hijackers, who are “demanding political asylum, demand to be taken to” New York City, according to a document later produced by the 9/11 Commission. As the scenario plays out, the FAA requests support from NORAD. The FAA directs the plane toward Jacksonville, Florida, but the hijackers then demand to be taken to Atlanta, Georgia. Finally, the hijacked plane lands safely at Dobbins Air Force Base in Georgia. [9/11 Commission, 2004] The following morning, September 11, personnel at NORAD’s Northeast Air Defense Sector (NEADS) in Rome, New York, are scheduled to practice what is apparently a similar plane hijacking scenario, presumably as part of the same Vigilant Guardian exercise (see (9:40 a.m.) September 11, 2001). According to Vanity Fair, that scenario will involve “politically motivated perpetrators” seeking asylum “on a Cuba-like island.” [Vanity Fair, 8/1/2006]
September 10, 2001: Key White House Officials Go to New York to Prepare for President’s UN Appearance
A group of White House staffers, including the deputy chief of staff for operations and the deputy director of the White House Military Office, goes to New York to prepare for President Bush’s forthcoming appearance at the United Nations General Assembly, and is consequently away from Washington, DC, when the terrorist attacks occur on September 11. [National Journal, 8/31/2002; Cincinnati Enquirer, 1/20/2003] Bush is scheduled to address the UN General Assembly’s annual gathering of world leaders on September 24. [Reuters, 9/12/2001; Associated Press, 10/29/2001] The group, which comprises about 15 members of the White House staff, heads to New York this afternoon to conduct the “survey trip” for his appearance. The group includes Joseph Hagin, the White House deputy chief of staff for operations, and Captain Michael Miller, the deputy director of the White House Military Office. During the evening, Hagin meets at the Waldorf-Astoria Hotel, where the group is staying, with Tony Carbonetti, New York City Mayor Rudy Giuliani’s chief of staff. The White House staffers are scheduled to meet with the staff at the US Mission to the United Nations on the morning of September 11. They will start making their way back to Washington after the attack on the Pentagon, and arrive at the White House later in the day (see After 9:37 a.m. September 11, 2001). [National Journal, 8/31/2002] It is unclear what effect the absence of these staffers has on the White House’s ability to respond to the 9/11 attacks. However, as the deputy chief of staff for operations, Hagin has an important role to play at the White House, so his absence could presumably be detrimental. Hagin is responsible for the management and administrative functions of the White House, and also plans all of the president’s travel. [Washington Post, 7/4/2008] He will describe himself as being responsible for “scheduling, advance, Oval Office operations, the White House Military Office, the liaison with the Secret Service, the Office of Management and Administration… and then the Office of Administration.” [Cohen et al., 2008, pp. 9 ] Hagin is “an operational wizard,” according to Politico, who “manages everything around the president and the presidency except politics and policy.” He is “the single junction where Bush’s personal life, presidency, security, and military support all come together.” [Politico, 7/3/2008]
September 10, 2001: New WTC Security Director Warns of Danger of ‘Something Big’
John O’Neill, who is later described by the New Yorker magazine as the FBI’s “most committed tracker of Osama bin Laden and his al-Qaeda network of terrorists,” recently retired from the bureau and started a new job as director of security at the World Trade Center (see August 23, 2001). [New Yorker, 1/14/2002] On this day he meets up with his old friend Raymond Powers, the former New York Police Department chief of operations, to discuss security procedures. Their conversation turns to Osama bin Laden. According to journalist and author Murray Weiss, “just as he had reiterated since 1995 to any official in Washington who would listen, O’Neill said he was sure bin Laden would attack on American soil, and expected him to target the Twin Towers again.” He says to Powers, “It’s going to happen, and it looks like something big is brewing.” [Weiss, 2003, pp. 355 and 359-360] Later on, O’Neill goes out in the evening with his friends Robert Tucker and Jerome Hauer. Again, he starts discussing bin Laden. He tells his friends, “We’re due. And we’re due for something big.” He says, “Some things have happened in Afghanistan. I don’t like the way things are lining up in Afghanistan.” This is probably a reference to the assassination of Afghan leader Ahmed Shah Massoud the previous day (see September 9, 2001). He adds, “I sense a shift, and I think things are going to happen.” Asked when, he replies, “I don’t know, but soon.” [New Yorker, 1/14/2002; PBS, 10/3/2002] O’Neill will be in his office on the 34th floor of the South Tower the following morning when the first attack occurs, and dies when the WTC collapses. [Weiss, 2003, pp. 366; Fox News, 8/31/2004]
