General John Keane, vice chief of staff of the Army, learns that a plane has crashed into the World Trade Center and consequently orders that the Army Operations Center (AOC) at the Pentagon be brought up to full manning. Keane is in his office at the Pentagon when one of his sergeants rushes into the room, tells him something terrible has happened in New York, and turns on the television. Keane sees the reports stating that a plane has hit the WTC and is immediately suspicious. “I noticed it was a blue-sky day and [thought] you could not hit the WTC by accident,” he will later recall. “I knew in 1993 terrorists had tried to bomb the WTC and bring it down from an underground parking garage,” he will say (see February 26, 1993). Therefore, he will recall, “I sensed it instinctively, what had happened, that this was a terrorist act.” He calls Major General Peter Chiarelli, the Army’s director of operations, readiness, and mobilization, who is in his office at the Pentagon, and tells him to bring the AOC up to full manning. [Fox News, 9/12/2011; Fordham News, 9/10/2016; Weekly Standard, 9/11/2016] The AOC, located in the basement of the Pentagon, is “the place that people will migrate” to during an emergency, according to Brigadier General Clyde Vaughn, the Army’s deputy director of operations, readiness, and mobilization. It is equipped with state-of-the-art communications equipment and television sets for monitoring news coverage. [Washington Post, 8/25/1995; US Army Center of Military History, 2/12/2002; Soldiers, 9/2004] Keane will subsequently see the second hijacked plane crashing into the WTC on television (see 9:03 a.m. September 11, 2001). Sometime after that, Chiarelli will call him to confirm that the AOC is fully manned (see Shortly Before 9:37 a.m. September 11, 2001). [Fordham News, 9/10/2016] The AOC will remain manned throughout today’s attacks and their aftermath. Keane will go to it after the Pentagon is attacked, to provide leadership and guidance (see (Shortly After 9:37 a.m.) September 11, 2001). [Goldberg et al., 2007, pp. 135; Christopher N. Koontz, 2011, pp. 56 
; Fox News, 9/12/2011] The Army’s Crisis Action Team, whose members assemble in the AOC, will be activated sometime after Keane orders Chiarelli to bring the operations center up to full manning (see (Shortly After 9:03 a.m.) September 11, 2001).

Shortly Before 9:37 a.m. September 11, 2001: Army Vice Chief of Staff Keane Talks with His Operations Officer about a Plane Approaching Washington
General John Keane, vice chief of staff of the Army, talks on the phone with Major General Peter Chiarelli, the Army’s director of operations, readiness, and mobilization, about a suspicious plane that is approaching Washington, DC, and the two men discuss evacuating buildings in the capital, including the Pentagon. Keane called Chiarelli from his office at the Pentagon after he learned a plane had crashed into the World Trade Center and instructed him to bring the Army Operations Center (AOC) at the Pentagon up to full manning (see (Between 8:49 a.m. and 9:02 a.m.) September 11, 2001).
Officer Is Monitoring FAA Communications – Sometime after the second hijacked plane crashed into the WTC (see 9:03 a.m. September 11, 2001), Chiarelli, who is now in the AOC himself, calls Keane to confirm that the operations center is fully manned. He also says he is monitoring FAA communications and all planes are being grounded, Keane will later recall. [Fordham News, 9/10/2016; Weekly Standard, 9/11/2016] (However, the FAA will only order its facilities to instruct aircraft to land at the nearest airport at around 9:45 a.m., which is later than this conversation occurs (see (9:45 a.m.) September 11, 2001). [US Congress. House. Committee On Transportation And Infrastructure, 9/21/2001; 9/11 Commission, 7/24/2004, pp. 29] )
Officer Was Told about an Aircraft Approaching Washington – Before Chiarelli left his office and went to the AOC, an intelligence analyst told him additional aircraft had been hijacked and one of them was thought to be heading toward Washington. An intelligence officer told him about this aircraft again after he reached the AOC (see (Shortly Before 9:37 a.m.) September 11, 2001). [US Army Center of Military History, 2/5/2002; Rossow, 2003, pp. 65-66] Presumably based, at least partly, on what these intelligence officers said, Chiarelli tells Keane about the suspicious aircraft, apparently Flight 77, which is now in the vicinity of Washington. [Fox News, 9/12/2011]
Officers Discuss Evacuating Buildings in Washington – He says, “There’s an airplane that has come up from I-95 south towards Washington, DC, and it turned east and went back down, and they’re tracking it.” He adds: “I think this airplane was out in Ohio someplace and it turned around (see (8:54 a.m.) September 11, 2001). It’s probably where they [i.e. hijackers] took charge of it and [air traffic controllers] haven’t been able to get a hold of it.” The two men conclude that the suspicious aircraft is heading for a building in the capital. Keane asks Chiarelli, “Well, what’s the plan to evacuate buildings in Washington?” Chiarelli replies, “I’ve already asked that question.” Keane then asks: “Well, what’s the plan to evacuate this building [i.e. the Pentagon]? Why isn’t it being evacuated?” What, if anything, Chiarelli says in response is unstated. [Weekly Standard, 9/11/2016] Keane and Chiarelli will still be holding this conversation at 9:37 a.m., when the Pentagon is hit (see 9:37 a.m. September 11, 2001), and will continue it after the attack occurs (see (Shortly After 9:37 a.m.) September 11, 2001). [Fordham News, 9/10/2016]
Shortly After 9:37 a.m. September 11, 2001: Army Vice Chief of Staff Keane Instructs His Operations Officer to Tell the Army around the World about the Pentagon Attack
General John Keane, vice chief of staff of the Army, instructs Major General Peter Chiarelli, the Army’s director of operations, readiness, and mobilization, to inform Army facilities around the world that the Pentagon has been attacked. Chiarelli headed from his office to the Army Operations Center (AOC) in the basement of the Pentagon sometime after the second hijacked plane crashed into the World Trade Center (see 9:03 a.m. September 11, 2001) and called Keane after he arrived there. During the conversation, he alerted Keane to a suspicious aircraft that had been flying toward Washington, DC (see Shortly Before 9:37 a.m. September 11, 2001). [US Army Center of Military History, 2/5/2002; Fordham News, 9/10/2016] The two men were still on the phone at 9:37 a.m., when the Pentagon attack occurred (see 9:37 a.m. September 11, 2001). Although the building was hit far away from where his office is located, Keane felt the room shake violently. He now asks Chiarelli if he too noticed the impact. “Did you hear that?” he says. Chiarelli says no. “Pete, that plane [that was approaching Washington] just hit us,” Keane says. He will later recall that he then instructs Chiarelli “to tell the US Army around the world what happened and that, given the status of the AOC, which was unharmed, we would still maintain command and control of the Army.” [Fordham News, 9/10/2016; Weekly Standard, 9/11/2016] Keane will subsequently join Chiarelli in the AOC (see (Shortly After 9:37 a.m.) September 11, 2001). [Goldberg et al., 2007, pp. 135; Fox News, 9/12/2011] From there, according to a report published by the Army, he will send “messages throughout the Army to inform subordinate commands that HQDA [Headquarters, Department of the Army] was still directing operations,” even though the Pentagon had been hit. [Christopher N. Koontz, 2011, pp. 56-57 ]
Shortly After 9:37 a.m. September 11, 2001: Army Vice Chief of Staff Keane Goes to Help People near the Pentagon Crash Site before Heading to His Operations Center
General John Keane, vice chief of staff of the Army, initially goes to assist people near the crash site after the Pentagon is hit but subsequently goes to the Army Operations Center (AOC) in the basement of the Pentagon to help the military respond to the terrorist attacks. Keane ordered Major General Peter Chiarelli, the Army’s director of operations, readiness, and mobilization, to bring the AOC up to full manning after he learned a plane had crashed into the World Trade Center (see (Between 8:49 a.m. and 9:02 a.m.) September 11, 2001). [Fordham News, 9/10/2016; Weekly Standard, 9/11/2016] The AOC is “the Army’s command and control center,” according to Chiarelli. [Soldiers, 9/2004] It is “the place that people will migrate” to during an emergency, according to Brigadier General Clyde Vaughn, the Army’s deputy director of operations, readiness, and mobilization. [US Army Center of Military History, 2/12/2002] And yet Keane did not go there himself in response to the attacks on the WTC and was still in his office when the Pentagon was hit. Although his office is located far away from where the attack occurred, it shook violently from the impact and subsequently started filling with smoke.
Keane Tells His Staffers to Go Home – Following the attack, Keane tells his immediate staff to call home and then evacuate. “Look, call your homes right now and make sure everybody knows you’re alright,” he says, “and then I want you to all to leave the building immediately.” He keeps just his executive officer and his aide with him, and decides to head to the scene of the attack. “Let’s go on down there and see if we can help some of these people,” he says. Keane and his colleagues grab some T-shirts, soak them in water, and wrap them around their noses and mouths for protection. They then make their way toward the crash site.
Keane Is Advised to Go to the Operations Center – About 100 yards from it, the smoke becomes thicker. People there are running away from the area of the attack. Keane and his two colleagues take time ensuring that everyone is able to get out of the Pentagon. After a while, though, Keane’s executive officer determines that they should be in the AOC. He tells Keane: “Look, you’ve got to take charge of the Army, so let’s get to the operations center. We’ll leave the recovery to other people.” “I knew immediately that he was right,” Keane will later comment. He and his two colleagues therefore go to the AOC. [Fordham News, 9/10/2016; Weekly Standard, 9/11/2016]
Keane Provides ‘Leadership and Guidance’ – When they get there, Keane talks to Chiarelli, who went to the operations center before the Pentagon was hit, and asks him for a situation report. Chiarelli says what he currently knows about the attacks. “I was able to tell [Keane] basically what had occurred at the World Trade Center,” he will recall, adding, “We were able to tell him that the [Pentagon] had been hit—he knew the building had been hit—and that there were other aircraft in the air.” [US Army Center of Military History, 2/5/2002; Lofgren, 2011, pp. 100] Keane subsequently provides “leadership and guidance” to the personnel in the AOC, according to a report published by the Army. [Christopher N. Koontz, 2011, pp. 56 ] He apparently stays in the operations center for the rest of the day. [Fordham News, 9/10/2016; Weekly Standard, 9/11/2016] Other senior Army leaders also go to the AOC following the attack on the Pentagon. [US Army Center of Military History, 2/5/2002; Rossow, 2003, pp. 67; Goldberg et al., 2007, pp. 135]
9:43 a.m. September 11, 2001: Army’s Crisis Team at the Pentagon Is ‘Formally Stood Up’ and Responds to Attacks
The Army’s Crisis Action Team (CAT) at the Pentagon is “formally stood up” and its members respond to the terrorist attacks. [Rossow, 2003, pp. 66; Goldberg et al., 2007, pp. 135; St. Louis Jewish Light, 9/8/2011] Lieutenant Colonel Kevin Stramara activated the CAT after the second hijacked aircraft crashed into the World Trade Center, at 9:03 a.m., on the orders of Major General Peter Chiarelli, the Army’s director of operations, readiness, and mobilization (see (Shortly After 9:03 a.m.) September 11, 2001). [US Army Center of Military History, 2/5/2002; Lofgren, 2011, pp. 96-97] Chiarelli’s intention was, he said, “to respond to the contingency in New York if requested by state and local officials.” [Goldberg et al., 2007, pp. 134] The CAT is now “formally stood up,” according to author Robert Rossow, although exactly what this means is unstated.
Senior Officials Come to Operations Center – When the CAT is activated, its members assemble in the Army Operations Center (AOC) in the basement of the Pentagon. [Rossow, 2003, pp. 64, 66] Numerous senior officials now start arriving in the AOC. These include General John Keane, vice chief of staff of the Army; Brigadier General Clyde Vaughn, deputy director of operations, readiness, and mobilization; Major General Philip Kensinger, assistant deputy chief of staff for operations and plans; and Thomas White, the secretary of the Army. More senior officers come to the AOC than would usually be the case in a crisis, according to Chiarelli, “because a large portion of the Army section of the building had been destroyed” in the attack on the Pentagon. “People had been forced out of their space,” he will later say, and “were looking for some place to go.” [US Army Center of Military History, 2/5/2002; US Army Center of Military History, 2/12/2002; Goldberg et al., 2007, pp. 135; Lofgren, 2011, pp. 98-101; Fox News, 9/12/2011]
Operations Center Personnel Unaware that a Plane Hit the Pentagon – Chiarelli arrived at the AOC shortly before the Pentagon was hit (see (Shortly Before 9:37 a.m.) September 11, 2001) and, he will recall, heard a “muffled noise” when the attack occurred, at 9:37 a.m. (see 9:37 a.m. September 11, 2001). [US Army Center of Military History, 2/5/2002; Lofgren, 2011, pp. 98-99] Colonel Henry Huntley, who also arrived at the AOC around the time of the Pentagon attack, will recall, “Alarms started going off and there was an announcement that an explosion had gone off in the building.” [Daily American, 7/8/2008] However, those in the AOC are apparently initially unaware that a plane has hit their building. Vaughn, who witnessed the attack from the road outside the Pentagon, calls Major George Sterling, the AOC commandant, and says to him, “You know that you’ve been hit by an airplane?” Sterling responds, “Is that what happened?” Vaughn will comment that “many people… didn’t find out for some time” that the Pentagon had been hit by an airplane. [US Army Center of Military History, 2/12/2002; Rossow, 2003, pp. 15-16; Lofgren, 2011, pp. 3-4]
Support Agency Commander Unaware that the US Is under Attack – Colonel Bruce Bachus, commander of the Command and Control Support Agency, who is responsible for keeping the AOC operating, arrived at the Pentagon around the time the attack there occurred and yet he is unaware of the crisis taking place in the US when he gets to the AOC. In the AOC, Dick Mansfield, deputy director of the Command and Control Support Agency, says to him: “We’ve been hit! The CAT has been stood up!” But Bachus appears to be puzzled. Mansfield therefore asks him, “Sir, do you know what’s going on?” Bachus says no and that he had not been listening to the radio—like he usually does—while he drove to work. He says he heard a loud sound while he was in the Pentagon’s A-E Drive, and saw people shouting and running down the corridors, but he’d had no idea what was going on. Mansfield therefore has to quickly brief him on the catastrophic events of the past hour. [Rossow, 2003, pp. 9, 68]
Crisis Team Assesses How Many Army Staffers Are Missing – The “first big task” for the CAT, according to Vaughn, is “to get a count on how many people were missing on the Army staff.” Chiarelli instructs Vaughn to focus on this assignment. Vaughn then announces on the CAT floor that he wants each section “to start that process of figuring out who was missing and who was not.” “For a long time, our number one priority was locating and identifying and taking care of… our soldiers and civilians,” Vaughn will say. [US Army Center of Military History, 2/12/2002] Lieutenant Colonel Richard Kotch, who is working in the AOC this morning, will recall that those in the operations center also “assured continuity of operations after the impact [i.e. the attack on the Pentagon].” [St. Louis Jewish Light, 9/8/2011]
Intelligence Officers Give Inaccurate Reports of Hijackings – Meanwhile, after he arrives at the AOC, Chiarelli receives reports from his intelligence officers informing him, inaccurately, about additional hijacked aircraft. He is told there are “a minimum of four aircraft that were hijacked and a possibility, at one time, [of] as high as seven.” [US Army Center of Military History, 2/5/2002; Lofgren, 2011, pp. 99]
Operations Center Has Sophisticated Equipment – The CAT, according to Soldiers magazine, “consists of a dedicated ‘hot’ desk with classified and unclassified computers, and secure telephones for 24 separate Army staff sections.” [Soldiers, 9/2004] The AOC, where its members assemble, is equipped with state-of-the-art communications equipment and has television sets for monitoring news coverage. [Washington Post, 8/25/1995] A glassed-in balcony overlooks the main floor and four giant screens are on the wall above the computer workstations. [US Army Center of Military History, 2/5/2002; Lofgren, 2011, pp. 99-100]
Watch Team Regularly Communicates with Government Agencies – AOC personnel usually work around the clock to keep senior Army leaders aware of issues and events around the world. A watch team monitors the world constantly and is ready to sound the alarm if a crisis erupts somewhere. The watch team also “directs hundreds of communications daily to the FBI, the State Department, the White House command center, local law enforcement agencies, and others,” according to Soldiers magazine. The AOC is equipped with an “emergency action console,” which is a switchboard with a sophisticated communications system that allows watch team members to contact, at the touch of a button, the White House, the secretary of defense’s office, and Army commands around the world. [Washington Post, 8/25/1995; Soldiers, 9/2004] The CAT will become “a focal point for all Pentagon activities” in response to the terrorist attacks, according to Kotch. [St. Louis Jewish Light, 9/8/2011] It will continue working around the clock in the aftermath of the attacks. [US Army Center of Military History, 2/5/2002]
11:00 a.m. September 11, 2001: Secretary of the Army White Is Unnecessarily Sent to a Secure Location outside Washington
Secretary of the Army Thomas White is ordered to leave the Pentagon and go to Site R, an alternate military command center outside Washington, DC, but the decision to send him there will subsequently be found to have been a mistake and so he will return to the Pentagon later in the day. [US Army Center of Military History, 2/5/2002; Christopher N. Koontz, 2011, pp. 57 ; Arkin, 2013, pp. 176] White arrived at the Army Operations Center (AOC) in the basement of the Pentagon sometime after 9:37 a.m., when the Pentagon was attacked (see 9:43 a.m. September 11, 2001). [US Army Center of Military History, 2/5/2002; PBS Frontline, 10/26/2004; Goldberg et al., 2007, pp. 135] While there, he has provided leadership and guidance to personnel in the center. [Christopher N. Koontz, 2011, pp. 56 ]
Army Secretary Is Ordered to Leave the Pentagon – After he has spent some time in the AOC, though, he is ordered to leave the Pentagon and go to Site R, a secure complex of buildings on the Pennsylvania-Maryland border. [Goldberg et al., 2007, pp. 135; Arkin, 2013, pp. 176] The facility was designed as a duplicate of the Pentagon’s National Military Command Center (NMCC) that would serve as the Pentagon’s primary command center if the NMCC was destroyed in an attack or needed to be evacuated. [Creed and Newman, 2008, pp. 174] White is ordered to go there by Major General Peter Chiarelli, the Army’s director of operations, readiness, and mobilization. Chiarelli will later recall that he issued the order to White after he “got word that we were going to exercise a relocation plan of key leaders to a place called Site R.”
White Initially Objects to Leaving the Pentagon – White is unhappy when he is first told that he has to leave the Pentagon and refuses to go. “He communicated he was not leaving, he was staying in the building,” Chiarelli will recall. But the officer in charge of the relocation and continuity of operations plan then explains to Chiarelli that White has to go to Site R. He says: “Sir, he has no choice at this time. This has been directed and he must immediately proceed to leave here. This is bigger than him. This is continuity of the government of the United States.” Chiarelli asks the officer, “Are you sure of this?” and the officer replies: “Yes, I’m sure. Sir, you need to go up and tell him he needs to get up and go.” Chiarelli therefore goes up to White and tells him that he has “no choice; he was bound to do this; we had gotten word that this portion of the implementation plan was in effect, and that he must proceed directly to a specified place in the building where he would get in a helicopter and leave.” White then agrees to go to Site R.
Order to Send White Away Will Be Found to Be Unnecessary – He leaves the Pentagon at the same time as Deputy Secretary of Defense Paul Wolfowitz does (see (11:00 a.m.) September 11, 2001) and the two men are flown to the secure facility in the same helicopter, according to Chiarelli. However, personnel in the AOC will subsequently discover that the decision to send White to Site R was a mistake. “We found out that it wasn’t required for him to leave at that particular point in time, because the level of evacuation did not reach his level,” Chiarelli will say. The unnecessary order came about because the person who said White had to leave the Pentagon “misspoke over the phone,” he will add. White will therefore return to the Pentagon about four hours after leaving it. [US Army Center of Military History, 2/5/2002]
Army Vice Chief of Staff Will Be in Charge While White Is Away – As secretary of the Army, White is the top civilian leader for the US Army and is responsible for the effective and efficient functioning of the Army. [US Department of the Army, 7/9/2002 ; USA Today, 4/7/2017] He is also the “top executive agent in the Pentagon hierarchy,” the “coordinator of continuity for the Pentagon,” and the “middleman for military support to civil authorities,” according to military expert and author William Arkin. But while he is away from the Pentagon, General John Keane, vice chief of staff of the Army, will be “in charge of the Army (and of decisions relating to military support to civil authorities),” Arkin will write. [Arkin, 2013, pp. 176]
