Brigadier General Montague Winfield, the deputy director for operations (DDO) in the National Military Command Center (NMCC) at the Pentagon, leaves his post to attend a pre-scheduled meeting, allowing a colleague, who only recently qualified to take over his position, to stand in for him, and not returning to his post until after the terrorist attacks have ended. [9/11 Commission, 7/21/2003 
; 9/11 Commission, 4/29/2004 ; 9/11 Commission, 6/17/2004]
Winfield Attends Air Force-Convened Meeting – Winfield leaves his post to attend what a 9/11 Commission memorandum will call “an unrelated, closed-door personnel meeting convened by the Air Force to discuss the rating of Air Force officers.” [9/11 Commission, 7/21/2003 ] Another Commission memorandum will state that this meeting is a “session for general officers who rated Air Force officers.” It is unclear whether the meeting takes place somewhere in the NMCC or outside the center. The Commission memorandum will only say that it takes place “elsewhere in [Joint Chiefs of Staff] spaces.” At least one of the NMCC’s other qualified DDOs, Brigadier General Norman Seip, is also attending it.
Winfield Asked Colleague to Replace Him on Previous Day – Winfield is temporarily replaced as DDO by Captain Charles Leidig. Leidig only joined the operations directorate of the Joint Chiefs of Staff in July 2001, when he assumed duties as the deputy for Command Center operations. In that, his usual role, he is responsible for the maintenance, operation, and training of watch teams for the NMCC. He qualified to stand in as the DDO in the NMCC about a month ago, in August 2001. The previous afternoon, Winfield asked Leidig to relieve him for a portion of his duty this morning, and Leidig agreed to do so.
Leidig Takes Over as DDO – As arranged, Leidig takes over from Winfield as DDO at 8:30 a.m., allowing Winfield to attend his meeting. Upon arrival at the NMCC, Leidig receives the intelligence and other turn over briefings. After seeing the reports of the plane crashes in New York on television, he will be responsible for convening a significant event conference (see 9:29 a.m.-9:34 a.m. September 11, 2001), which he soon upgrades to an air threat conference (see 9:37 a.m.-9:39 a.m. September 11, 2001). [9/11 Commission, 4/29/2004 ; 9/11 Commission, 6/17/2004 ]
Winfield Does Not Resume Duties until Attacks Are Over – Even though it becomes obvious that a coordinated attack is under way when television shows the second plane hitting the World Trade Center at 9:03 a.m. (see 9:03 a.m. September 11, 2001), Winfield apparently remains in his meeting instead of resuming his duties as DDO (see (Shortly After 9:03 a.m.) September 11, 2001). He will only take over from Leidig as DDO after Flight 93 crashes in Pennsylvania, apparently at around 10:30 a.m. (see (10:30 a.m.) September 11, 2001). [9/11 Commission, 4/29/2004 ; 9/11 Commission, 6/17/2004] In later interviews for television, Winfield will give the impression that he remained in charge of the NMCC throughout the 9/11 attacks, and make no mention of having allowed a stand-in to take his place during this most critical period of time. [CNN, 9/4/2002; ABC News, 9/11/2002]
8:38 a.m.-9:28 a.m. September 11, 2001: NORAD Does Not Contact Pentagon Command Center about the Hijackings
NORAD fails to notify the National Military Command Center (NMCC) at the Pentagon that aircraft have been hijacked before the NMCC initiates a significant event conference in response to the terrorist attacks. [9/11 Commission, 6/9/2004] NORAD’s Northeast Air Defense Sector (NEADS) was alerted to the first hijacking, of Flight 11, at 8:37 a.m. (see (8:37 a.m.) September 11, 2001) and it is alerted to the second hijacking, of Flight 175, at 9:03 a.m. (see (9:03 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20, 23] And yet, according to an after-action report produced by the NMCC, NORAD does not contact the NMCC to alert it to these incidents before the significant event conference commences, at 9:29 a.m. (see 9:29 a.m.-9:34 a.m. September 11, 2001). [9/11 Commission, 6/9/2004]
NORAD Does Not Provide Information to Deputy Director – Captain Charles Leidig, the acting deputy director for operations in the NMCC, will later say that he “does not remember getting a lot of information from NORAD” before the significant event conference begins. [9/11 Commission, 4/29/2004 ] NMCC personnel apparently learn that an aircraft has been hijacked when an officer in the center calls the FAA at 9:00 a.m. (see 9:00 a.m. September 11, 2001). [9/11 Commission, 4/29/2004 ; 9/11 Commission, 5/5/2004; 9/11 Commission, 7/24/2004, pp. 35]
NORAD First Mentions a Hijacking at 9:33 a.m. – NORAD will apparently talk to the NMCC about a hijacking for the first time at around 9:33 a.m., when its representative on the significant event conference states that they “concur that [a] hijacked aircraft is still airborne [and] heading towards Washington, DC.” [US Department of Defense, 9/11/2001 ; US Department of Defense, 9/11/2001 ] (They will presumably be referring to the incorrect information that Flight 11 is still in the air after it has crashed into the World Trade Center (see 9:21 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 26] )
NORAD Does Not Request a Conference – Additionally, according to the NMCC’s after-action report, NORAD “does not request any conference at [National Command Authority] level” prior to the commencement of the significant event conference. [9/11 Commission, 6/9/2004] The significant event conference is actually initiated by Leidig. The NMCC has an important role to play in an emergency like the current crisis. Its job under these circumstances “is to gather the relevant parties and establish the chain of command between the National Command Authority—the president and the secretary of defense—and those who need to carry out their orders,” according to the 9/11 Commission Report. [9/11 Commission, 4/29/2004 ; 9/11 Commission, 7/24/2004, pp. 37] It is also “the focal point within [the] Department of Defense for providing assistance” when there is a hijacking in US airspace, according to a recent military instruction (see June 1, 2001). [US Department of Defense, 6/1/2001 ]
Between 8:49 a.m. and 9:02 a.m. September 11, 2001: NMCC Responds to First Crash at WTC, Notifies Senior Pentagon Officials
Officers in the National Military Command Center (NMCC) at the Pentagon begin notifying senior Pentagon officials about the plane crashing into the World Trade Center after learning of this from television, but they are apparently unaware of the hijacking of Flight 11. [9/11 Commission, 7/21/2003 ; 9/11 Commission, 4/29/2004 ; 9/11 Commission, 7/24/2004, pp. 35] The NMCC’s three main missions are monitoring worldwide events for the Joint Chiefs of Staff (JCS), maintaining a strategic watch component, and maintaining a crisis response component. The NMCC has live feeds from numerous television stations, and the operations team on duty there learned from CNN that an aircraft had hit the WTC (see (8:48 a.m.) September 11, 2001).
NMCC Directors Notify Senior Pentagon Officials of Crash – In response, members of the operations team monitor media reports and begin making notifications up the chain of command. [9/11 Commission, 7/21/2003 ; 9/11 Commission, 4/29/2004 ] Captain Charles Leidig, who is currently standing in temporarily as deputy director for operations in the NMCC (see 8:30 a.m. September 11, 2001), will later recall, “Initially… the National Military Command Center was primarily a means to notify senior leadership that, in fact, an event had occurred.” [9/11 Commission, 6/17/2004] Leidig and Commander Patrick Gardner, the assistant deputy director for operations, start notifying those on the internal JCS notification list, including the office of the chairman of the Joint Chiefs of Staff, about the crash. They also notify the office of the secretary of defense. Based on incorrect information being reported on television, Leidig tells the senior Pentagon officials that a small airplane has crashed into one of the towers of the WTC. [9/11 Commission, 4/29/2004 ; 9/11 Commission, 7/24/2004, pp. 35]
NMCC Unaware of Flight 11 Hijacking – According to military instructions, “the NMCC is the focal point within [the] Department of Defense for providing assistance” in response to aircraft hijackings in US airspace, and, “In the event of a hijacking, the NMCC will be notified by the most expeditious means by the FAA” (see June 1, 2001). [US Department of Defense, 6/1/2001 ] However, while details of the hijacking of Flight 11 have been circulating within the FAA, the 9/11 Commission will say it “found no evidence that the hijacking was reported to any other agency in Washington before 8:46.” The NMCC apparently learns of the hijacking for the first time when one of its officers calls the FAA at 9:00 a.m. (see 9:00 a.m. September 11, 2001). Leidig will recall that, before the second plane hits the WTC at 9:03 a.m., he and Gardner think it is “something unusual… that a light plane had crashed into the WTC and that there was a report of a hijacking.” [9/11 Commission, 4/29/2004 ; 9/11 Commission, 7/24/2004, pp. 35, 462]
Shortly After 9:03 a.m. September 11, 2001: Pentagon Command Center Director Does Not Return to Post, Even though Officials Conclude that US Is under Attack
Brigadier General Montague Winfield, the deputy director for operations (DDO) in the National Military Command Center (NMCC) at the Pentagon, apparently remains in a pre-scheduled meeting that is unrelated to the terrorist attacks and does not resume his key duties as DDO, even though others in the NMCC have concluded that the US is under attack. [9/11 Commission, 4/29/2004 ; American Forces Press Service, 9/7/2006] Since around 8:30 a.m., Winfield has been attending what the 9/11 Commission will describe as a “closed-door personnel meeting convened by the Air Force to discuss the rating of Air Force officers.” Captain Charles Leidig, who only qualified to stand in as the DDO about a month previously, has taken over Winfield’s position while he is in the meeting (see 8:30 a.m. September 11, 2001).
NMCC Officers Realize US Is under Attack – Leidig will later recall that after those in the NMCC see Flight 175 crashing into the World Trade Center live on television at 9:03 a.m., “[t]o him it was obvious it was a terrorist attack or a coordinated attack.” [9/11 Commission, 7/21/2003 ; 9/11 Commission, 4/29/2004 ] Other officers in the NMCC also realize this is a terrorist attack (see 9:03 a.m. September 11, 2001). [American Forces Press Service, 9/7/2006] Winfield himself will later describe, “When the second aircraft flew into the second tower, it was at that point that we realized that the seemingly unrelated hijackings that the FAA was dealing with were in fact a part of a coordinated terrorist attack on the United States.” [ABC News, 9/14/2002]
Winfield Stays in Pre-Scheduled Meeting – According to the 9/11 Commission Report, “The job of the NMCC in such an emergency is to gather the relevant parties and establish the chain of command between the National Command Authority—the president and the secretary of defense—and those who need to carry out their orders.” [9/11 Commission, 7/24/2004, pp. 37] However, Winfield does not return to his post, and apparently remains in the Air Force-convened meeting. The reason for this is unclear. According to one 9/11 Commission memorandum, “Such meetings” as Winfield is attending “are generally not disturbed unless the reason is significant.” Winfield will only resume his duties as DDO after Flight 93 crashes in Pennsylvania, apparently at around 10:30 a.m. (see (10:30 a.m.) September 11, 2001). [9/11 Commission, 4/29/2004 ; 9/11 Commission, 6/17/2004] Whether Winfield and the other officers with him in the meeting learn that America is under attack immediately, or are only notified of this later on, is unstated.
Between 9:16 a.m. and 9:25 a.m. September 11, 2001: Washington-Area Conference Call Convened by CIA, but Is of Little Benefit
A National Operations and Intelligence Watch Officer Network (NOIWON) conference call is established to allow government agencies in the Washington, DC, area to quickly share information regarding the ongoing events, but the call reportedly contributes little of value to the emergency response to the terrorist attacks. [Federal Aviation Administration, 9/11/2001; Federal Aviation Administration, 9/11/2001; 9/11 Commission, 4/29/2004 ; 9/11 Commission, 7/13/2004; Government Executive, 6/1/2009] The NOIWON call is convened by the CIA sometime between 9:16 a.m. and 9:25 a.m., according to FAA chronologies. [Federal Aviation Administration, 9/11/2001; Federal Aviation Administration, 9/11/2001; Federal Aviation Administration, 9/17/2001 ] According to an officer at the Pentagon, the White House Situation Room is taking the lead at the time he answers the NOIWON call. [9/11 Commission, 5/5/2004]
FAA Participates in Call – At the FAA headquarters in Washington, the NOIWON call is answered by Bart Merkley, one of two officers on duty in the ACI Watch—a small, 24-hour intelligence facility located on the building’s third floor. [9/11 Commission, 7/13/2004] Merkley stays on the call for its entire duration. He passes onto it information he has learned from the Tactical Net—a teleconference established by the operations center at FAA headquarters at 8:50 a.m. [Federal Aviation Administration, 9/17/2001 ; 9/11 Commission, 5/19/2004]
NMCC Participates in Call – At the National Military Command Center (NMCC) at the Pentagon, the initial call on the NOIWON line is answered by Commander Pat Gardner, the assistant deputy director for operations. [9/11 Commission, 5/5/2004] Subsequently, Brigadier General Norman Seip will take over the line and remain on it for most of the day. According to a 9/11 Commission memorandum, this is because the “White House Situation Room insisted on having a flag officer on an open line” with it. [9/11 Commission, 7/21/2003 ]
NOIWON Call of Little Use – The NOIWON call apparently contributes little of value to the emergency response to the terrorist attacks. Darrel Smith, who is working alongside Merkley in the ACI Watch at FAA headquarters, will tell the 9/11 Commission that he “does not remember any useful or significant information coming as a result of the NOIWON call.” [9/11 Commission, 7/13/2004] Captain Charles Leidig, the acting deputy director for operations in the NMCC throughout the attacks, will tell the Commission that he “recalled no situational awareness that came from the NOIWON call.” [9/11 Commission, 4/29/2004 ] Gardner will say he “doesn’t remember specifically what was discussed” on the call. [9/11 Commission, 5/5/2004] FAA records will state, “It is believed that the [Department of Defense] received information” concerning the attacks over the NOIWON call, but the FAA “holds no records of that communication.” [Federal Aviation Administration, 9/11/2001]
Call Delays Establishing of NMCC’s Conference – Furthermore, the NOIWON call delays the Pentagon’s response to the attacks. The NMCC’s usual first action in response to a crisis is to establish a “significant event conference” in order to gather and disseminate information from government agencies, and discuss what actions should be taken. However, the NOIWON call reportedly intervenes with the preparations for such a conference call. According to a 9/11 Commission memorandum, “The NMCC abandoned its attempt to convene a [significant event conference] so its watch officers could participate in the NOIWON conference.” [9/11 Commission, 7/21/2003 ; 9/11 Commission, 6/17/2004] The significant event conference will therefore only commence at 9:29 a.m. (see 9:29 a.m.-9:34 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 37]
No Recording of Call – The NOIWON is described as “a dedicated secure telephone system with a conferencing capability for the rapid exchange and sharing of high interest and time-sensitive information between Washington-area operations centers.” [Government Executive, 6/1/2009] During breaking crises it is used by the major national security watch centers around Washington, including the NMCC and the National Military Joint Intelligence Center at the Pentagon, the State Department Operations Center, the State Department’s Bureau of Intelligence and Research, the CIA’s operations center, the NSA’s operations center, and the White House Situation Room. [Radi, 3/1997 ] The 9/11 Commission will later request a transcript of the NOIWON call conducted on this day, but despite “multiple searches,” no recording of it will be found. [9/11 Commission, 8/22/2003; Stephen A. Cambone, 10/14/2003; 9/11 Commission, 4/16/2004]
9:29 a.m.-9:34 a.m. September 11, 2001: Pentagon Command Center Holds Significant Event Conference Call
The National Military Command Center (NMCC) at the Pentagon finally commences and runs a “significant event conference” in response to the ongoing crisis, 26 minutes after the second plane hit the World Trade Center and officers in the NMCC realized the US was under terrorist attack. [9/11 Commission, 6/17/2004 ; 9/11 Commission, 7/24/2004, pp. 37; American Forces Press Service, 9/7/2006]
NMCC Directors Decided to Establish Conference – After those in the NMCC saw Flight 175 hitting the WTC live on television at 9:03 a.m. (see 9:03 a.m. September 11, 2001), Captain Charles Leidig, the acting deputy director for operations (DDO) in the center throughout the attacks, and Commander Pat Gardner, the assistant DDO, talked about the need to convene a significant event conference so there could be a discussion of what actions were to be taken in response. The DDO and the assistant DDO are the two officers responsible for deciding what type of conference the NMCC should convene, and when it should do so. Because there is no specific procedure for dealing with terrorist attacks, Leidig and Gardner decided a significant event conference would most suit their needs, because it would have the flexibility of allowing more people to be added in as required. They also discussed who would need to be on this conference. [9/11 Commission, 4/29/2004 ] But Major Charles Chambers, who is currently on duty in the NMCC, will give a slightly different account. According to Chambers, Staff Sergeant Val Harrison had a phone in her hand and said NORAD was asking for a significant event conference. Leidig had agreed, and so Harrison started establishing the conference.
Conference Begins with Recap of Situation – According to Chambers, “The computer does a mass dialing to connect to those command centers that are always included” in an NMCC conference call, but Harrison also had to manually call the civilian agencies that were going to be included in the conference, such as the FAA, the FBI, and the Federal Emergency Management Agency (FEMA). [US Department of Defense, 9/2001] The conference then begins at 9:29 a.m. with a brief recap: Two aircraft have hit the WTC, there is a confirmed hijacking of Flight 11, and fighter jets have been scrambled from Otis Air National Guard Base in Massachusetts (see 8:46 a.m. September 11, 2001). The FAA is asked to provide an update, but its line is silent as the agency has not yet been added to the call (see (9:29 a.m.-12:00 p.m.) September 11, 2001). A minute later, Leidig states that it has just been confirmed that Flight 11 is still airborne and is heading toward Washington, DC. (This incorrect information apparently arose minutes earlier during a conference call between FAA centers (see 9:21 a.m. September 11, 2001).) [9/11 Commission, 7/24/2004, pp. 37] NMCC conference calls are moderated by the DDO. [9/11 Commission, 7/21/2003 ] Leidig will tell the 9/11 Commission that they are conducted over “a special phone circuit, and it’s classified to be able to pass information, relay information between very senior leadership all the way over to the White House.” [9/11 Commission, 6/17/2004]
NMCC Struggled to Convene Conference – Some officers currently on duty in the NMCC will later complain about circumstances that delayed the establishing of the significant event conference. Chambers will recall that the conference took “much longer than expected to bring up.” [US Department of Defense, 9/2001] Gardner will tell the 9/11 Commission that the NMCC had been “struggling to build the conference,” which “didn’t get off as quickly as hoped.” [9/11 Commission, 5/5/2004] He will describe his “frustration that it wasn’t brought up more quickly.” [9/11 Commission, 5/12/2004]
Other Conference and Connection Problems Delayed Call – Preparations for the conference were disrupted as a result of the CIA convening a National Operations and Intelligence Watch Officer Network (NOIWON) conference call between government agencies in the Washington area, reportedly at sometime between 9:16 a.m. and 9:25 a.m. (see (Between 9:16 a.m. and 9:25 a.m.) September 11, 2001). According to a 9/11 Commission memorandum, the NMCC had “abandoned its attempt to convene a [significant event conference] so its watch officers could participate in the NOIWON conference.” [Federal Aviation Administration, 9/11/2001; Federal Aviation Administration, 9/11/2001; 9/11 Commission, 7/21/2003 ] Another factor that slowed attempts to convene the significant event conference was a problem with connecting some agencies to it. According to Chambers, “A couple of the civil agencies couldn’t be reached and others kept dropping off moments after connecting.” He will recall, “We finally decided to proceed without those agencies that were having phone problems.” [US Department of Defense, 9/2001] Leidig had announced that the NMCC would have to start without those agencies and add them to the conference later on. [9/11 Commission, 5/12/2004]
Call Ends after Five Minutes – The significant event conference ends after only a few minutes, following a recommendation by NORAD that it be reconvened as an “air threat conference.” It is brought to an end at around 9:34 a.m., and will resume as an air threat conference at 9:37 a.m. (see 9:37 a.m.-9:39 a.m. September 11, 2001). [9/11 Commission, 4/29/2004 ; 9/11 Commission, 7/24/2004, pp. 37]
9:29 a.m.-12:00 p.m. September 11, 2001: Pentagon Command Center Struggles to Connect FAA to Conference Calls
Officers at the National Military Command Center (NMCC) at the Pentagon have serious problems trying to connect the FAA to the conference calls they convene in response to the terrorist attacks. [US Department of Defense, 9/2001; 9/11 Commission, 7/21/2003 ; 9/11 Commission, 6/17/2004] The NMCC commences a “significant event conference” at 9:29 a.m., to gather and disseminate information relating to the crisis from government agencies (see 9:29 a.m.-9:34 a.m. September 11, 2001). Minutes later, this is upgraded to an “air threat conference” (see 9:37 a.m.-9:39 a.m. September 11, 2001). According to the 9/11 Commission Report, operators at the NMCC work “feverishly to include the FAA” in the conference, but they have “equipment problems and difficulty finding secure phone numbers.” [9/11 Commission, 7/21/2003 ; 9/11 Commission, 7/24/2004, pp. 37]
NMCC Unable to Connect to FAA – The FAA is not on the NMCC’s established checklist of parties to call for either a significant event conference or an air threat conference. Captain Charles Leidig, the acting deputy director for operations (DDO) in the NMCC during the attacks, therefore has to ask Staff Sergeant Val Harrison to add the FAA to the air threat conference. Harrison tries contacting the operations center at FAA headquarters in Washington, DC, but has difficulty getting through. She finally asks the White House switchboard to help her connect the call to the FAA, but even after a line has been established it is repeatedly lost. [US Department of Defense, 9/2001; 9/11 Commission, 7/21/2003 ] According to Leidig, the FAA is only “intermittently in,” and “[m]ost of the time they were not in the conference.”
NMCC Establishes Non-Secure Line with FAA – Commander Pat Gardner, the assistant DDO, has to set up an unclassified line with the FAA, because the agency’s only STU-III secure phone is tied up. This unclassified line is separate to the conference call, which is on a special, classified phone circuit. [9/11 Commission, 4/29/2004 ; 9/11 Commission, 6/17/2004] According to Major Charles Chambers, who is currently on duty in the NMCC, because it isn’t in the NMCC’s conference, the FAA “couldn’t go secure and so we couldn’t get first-hand information from them.” [US Department of Defense, 9/2001]
Connection Problems ‘Hampered Information Flow’ – Leidig is frustrated at being unable to keep the FAA in the conference. Sometimes questions are asked of the agency, but it is no longer on the line and so the NMCC has to redial it. [9/11 Commission, 4/29/2004 ] Leidig will tell the 9/11 Commission that the connection problems, which occur “throughout the morning… hampered information flow to some degree,” because the NMCC is “getting information in a more roundabout way from FAA. Sometimes it would come from a local commander to NORAD back to us, or sometimes it would come on an open line” with the FAA operations center, rather than over the conference. Leidig will add that if the FAA “had been in the same conference that was being directed by the National Military Command Center, the information flow would have went directly to NORAD because [NORAD was] in that conference.” [9/11 Commission, 6/17/2004]
FAA Employee Joins Conference – According to Harrison, the NMCC is not presently aware of the existence of the FAA Command Center in Herndon, Virginia, and also does not realize that there is a military liaison at the FAA operations center. [9/11 Commission, 7/21/2003 ] However, at 10:17 a.m., FAA representative Rayford Brooks, who is at the agency’s Command Center, finally joins the air threat conference (see 10:17 a.m. September 11, 2001), although accounts indicate there are problems keeping him connected after that time. [9/11 Commission, 4/15/2004; 9/11 Commission, 6/17/2004; 9/11 Commission, 7/24/2004, pp. 37, 463]
‘Compatibility Issues’ Supposedly Cause Connection Problems – The FAA keeps getting cut off the NMCC conference because of “technical problems,” according to a 9/11 Commission memorandum. [9/11 Commission, 7/21/2003 ] Leidig will tell the Commission it is his understanding that there were some “compatibility issues” between the FAA’s secure phone and the secure phones in the NMCC, and these caused the FAA to keep dropping out of the conference, although he is unaware of the technical aspects of the problem. [9/11 Commission, 6/17/2004]
9:37 a.m. September 11, 2001: Vice Chairman Myers’s Executive Assistant Talks on the Phone with Chairman of the Joint Chiefs Shelton’s Plane
Colonel Matthew Klimow, executive assistant to General Richard Myers, vice chairman of the Joint Chiefs of Staff, talks on the phone with either General Henry Shelton, chairman of the Joint Chiefs of Staff, or Lieutenant Commander Suzanne Giesemann, one of Shelton’s aides, and alerts them to the attack on the Pentagon soon after it occurs. [Giesemann, 2008, pp. 24; George C. Marshall European Center for Security Studies, 8/3/2012] Shelton is currently flying across the Atlantic Ocean for a NATO meeting in Europe (see 7:15 a.m. September 11, 2001) and Giesemann is accompanying him. They were both alerted to the crashes at the World Trade Center shortly after the attacks occurred and in response, Shelton gave the order for his plane to turn around and head back to the US (see (8:50 a.m.-10:00 a.m.) September 11, 2001). [Giesemann, 2008, pp. 21-23; Shelton, Levinson, and McConnell, 2010, pp. 430-431] Klimow is at the Pentagon and has seen the news of the crashes at the WTC on television. He has been participating in the conference call convened by the National Military Command Center (NMCC) at the Pentagon at 9:29 a.m. (see 9:29 a.m.-9:34 a.m. September 11, 2001 and 9:37 a.m.-9:39 a.m. September 11, 2001).
Executive Assistant Is Alerted to the Call from Shelton’s Plane – After Klimow has been on the conference call for a short time, Mary Turner, his secretary, tries to get his attention. Annoyed at the interruption, though, he tells her: “Mary, no, not now. I’m taking notes.” But Turner is undeterred and starts waving her hands at him. She then says Shelton is calling on the unsecured phone, Klimow will later recall. “He wants to talk, now. He’s calling from his airplane,” she adds. But Giesemann will write that she, not Shelton, makes the call from Shelton’s plane at this time. She will describe calling Shelton’s office at the Pentagon and reaching Klimow there.
Executive Assistant Updates the Caller – While still listening to the conference call on his secure phone, Klimow picks up his unsecured phone to talk to either Shelton or Giesemann. He will recall Shelton snapping at him, “Klimow, what the devil is going on back there?” to which he replies: “Sir, I’m on the Red Switch [secure phone] with the White House and NORAD. I’ll relay information.” But according to Giesemann, Klimow tells her: “Suzanne, this is really bad. The scenes on TV are unbelievable.” He then says, “You guys need to get back here right away” and Giesemann replies, “We’re coming now.”
Secretary Feels the Pentagon Move – Klimow’s secretary notices when the Pentagon is attacked, at 9:37 a.m. (see 9:37 a.m. September 11, 2001). Klimow will recall that as he is passing on the information he is hearing over the conference call to Shelton’s plane, Turner, who is sitting next to him, suddenly stands up and exclaims, “My God, the building moved.” He then notices “pandemonium” outside his door, with people running down the corridor, yelling and shouting. However, with his attention focused on two phone calls, he hadn’t noticed the building moving or heard anything unusual when the Pentagon was hit. Annoyed, he therefore instructs his secretary: “Mary, close the door. I can’t hear.” Giesemann will describe noticing the turmoil at the Pentagon, with the sound of shouting in the background coming over her headphones. “What’s all that commotion, Colonel?” she asks and Klimow replies: “I’m not sure. Stand by, Suzanne.” [Giesemann, 2008, pp. 24; George C. Marshall European Center for Security Studies, 8/3/2012]
Crash Is Reported over the Conference Call – Klimow learns what happened when, at 9:39 a.m., Captain Charles Leidig, the acting deputy director for operations in the NMCC, states over the conference call, “There’s a report that an aircraft has crashed into the Mall side of the Pentagon.” A couple of minutes later, Klimow checks this information with Leidig, asking him, “Do we confirm that [an] aircraft crashed into the building?” and Leidig replies: “On live TV you can now see smoke emitting from the Pentagon. Yes, sir. It’s confirmed.” [US Department of Defense, 9/11/2001 ; US Department of Defense, 9/11/2001 ]
Executive Assistant Tells the Caller about the Pentagon Attack – Klimow passes on news of the attack to either Shelton or Giesemann. According to his own recollection, he tells Shelton: “Sir, we’ve been hit. The Pentagon’s been hit by an airplane. Turn your aircraft around. Get back to Washington.” The call then ends. [George C. Marshall European Center for Security Studies, 8/3/2012; Graff, 2019, pp. 98] But Giesemann will recall him saying: “Something’s happened here at the Pentagon. I think a bomb exploded, but we’re still trying to find out what it was.” He then tells her, “I have to go.” [Giesemann, 2008, pp. 24] Klimow will subsequently tell Leidig over the conference call that he has informed Shelton’s plane about the Pentagon attack. “I’ve passed all the information that you just said to General Shelton’s aircraft,” he will say, adding, “I’ve had comms with him consistently but he just dropped.” [US Department of Defense, 9/11/2001 ] A short time later, he will receive a call from Myers, who is being driven back to the Pentagon from a meeting on Capitol Hill (see (Before 9:58 a.m.) September 11, 2001). [George C. Marshall European Center for Security Studies, 8/3/2012]
9:37 a.m.-9:39 a.m. September 11, 2001: Pentagon Command Center Begins Air Threat Conference Call
The National Military Command Center (NMCC) at the Pentagon commences an “air threat conference” at 9:37 a.m. in response to the terrorist attacks, which will last for more than eight hours and have numerous high-level government and military officials participating at various times.
NORAD Reports Two More Hijackings – Captain Charles Leidig opens the call at 9:39 a.m. [9/11 Commission, 7/24/2004, pp. 37-38] As the acting deputy director for operations (DDO) in the NMCC during the attacks, Leidig is responsible for moderating the air threat conference and generating a military response to the crisis. [9/11 Commission, 4/29/2004 ] He begins the call saying: “An air attack against North America may be in progress. NORAD, what’s the situation?” NORAD says it has conflicting reports, and its latest information is of “a possible hijacked aircraft taking off out of JFK [International Airport in New York], en route to Washington, DC.” [9/11 Commission, 7/24/2004, pp. 38] NORAD says the FAA has also passed it information about a second additional hijacking. Major Charles Chambers, who is currently on duty in the NMCC, will later recall, “This was probably a communications mix-up, but we all thought for a while that there were a total of five hijackings.” [US Department of Defense, 9/2001]
NMCC Reports Pentagon Attack – The NMCC reports that there has been a crash into the mall side of the Pentagon and requests that the secretary of defense be added to the conference. (However, despite being in the Pentagon when it is hit, Defense Secretary Donald Rumsfeld will not enter the NMCC and join the air threat conference until around 10:30 a.m. (see (10:30 a.m.) September 11, 2001).) [9/11 Commission, 7/24/2004, pp. 38] The air threat conference is broadcast over a loudspeaker inside the NMCC. [US News and World Report, 8/31/2003] According to Chambers, “Questions were flying left and right on the conference, and trying to keep things straight was very difficult.” [US Department of Defense, 9/2001]
NORAD Recommended Air Threat Conference – Leidig and Commander Pat Gardner, the assistant DDO, had earlier on decided to convene an all-purpose “significant event conference” in response to the attacks on the World Trade Center. That call commenced at 9:29 a.m. (see 9:29 a.m.-9:34 a.m. September 11, 2001). NORAD had recommended that it be reconvened as an air threat conference. [9/11 Commission, 4/29/2004 ; 9/11 Commission, 7/24/2004, pp. 37] According to Chambers, an air threat conference is used when aircraft are considered to be hostile and involves many more people than are in a significant event conference, including the chairman of the Joint Chiefs of Staff, the secretary of defense, and officials from the White House. [US Department of Defense, 9/2001] However, Leidig thought a significant event conference was the correct kind of call for the situation. He will tell the 9/11 Commission that an air threat conference “had Cold War implications and brought a different group of people to a conference.” [9/11 Commission, 4/29/2004 ] Gardner will say that threat conferences are intended for dealing with external threats. [9/11 Commission, 5/12/2004]
Deputy Director Ordered Upgrading of Conference – All the same, Leidig gave the order to transition to an air threat conference. [9/11 Commission, 7/24/2004, pp. 37] He will tell the 9/11 Commission that, in retrospect, the reason he thinks he did so “was because he perceived an air threat at that time.” [9/11 Commission, 4/29/2004 ] Therefore, the significant event conference was brought to an end at around 9:34 a.m., and resumes as an air threat conference three minutes later. [9/11 Commission, 7/24/2004, pp. 37] Staff Sergeant Val Harrison could have established the air threat conference either by leaving all of those participating in the significant event conference on the line and then adding new participants one at a time, or by simply hanging up on everyone in the significant event conference and then having the computer do a mass dialing. Harrison recommended the second option. Leidig had agreed, and directed her to disconnect the conference call and start over.
Problem with Connecting Some Agencies – As happened with the significant event conference, there are problems connecting several agencies to the air threat conference. [US Department of Defense, 9/2001] Despite repeated attempts, operators struggle to get the FAA connected (see (9:29 a.m.-12:00 p.m.) September 11, 2001), and it will take until 10:17 a.m. for an FAA representative to finally join the call (see 10:17 a.m. September 11, 2001). [9/11 Commission, 7/21/2003 ; 9/11 Commission, 7/24/2004, pp. 37] Other agencies had not understood what Leidig meant about convening the new conference, and so did not hang up their phones when the NMCC disconnected the previous conference call. As a result, all the NMCC got from them was a busy signal over the line. Chambers will recall, “As with the [significant event conference], it took longer than expected to convene the [air threat conference].” [US Department of Defense, 9/2001]
Top Officials Participate – Throughout the more than eight hours the air threat conference is running for, numerous key officials will participate in it at various times, including President Bush, Vice President Dick Cheney, Deputy National Security Adviser Stephen Hadley, acting Chairman of the Joint Chiefs of Staff Richard Myers, military personnel from the Presidential Emergency Operations Center below the White House, and the president’s military aide on Air Force One. [9/11 Commission, 7/24/2004, pp. 37] Brigadier General Montague Winfield, the original DDO, who had Leidig take his place so he could attend a pre-scheduled meeting (see 8:30 a.m. September 11, 2001), will later recall, “All of the governmental agencies… that were involved in any activity that was going on in the United States… were in that conference.” [ABC News, 9/11/2002]
Winfield Runs Conference after Returning to Post – Winfield will take over the running of the air threat conference from Leidig after returning to his post at around 10:30 a.m. (see (10:30 a.m.) September 11, 2001). [CNN, 9/4/2002; 9/11 Commission, 4/29/2004 ; 9/11 Commission, 6/17/2004] But although NMCC conference calls are moderated by the DDO, Rumsfeld will use the DDO’s phone to participate in the air threat conference, meaning that Winfield is unable to moderate the conference when the defense secretary is participating. [9/11 Commission, 7/21/2003 ]
9:39 a.m. September 11, 2001: Defense Secretary Rumsfeld Is Wanted at Pentagon Teleconference but Cannot Be Reached
Captain Charles Leidig, a deputy who is temporarily in charge of the Pentagon’s National Military Command Center (NMCC), is handling the NMCC’s crisis teleconference. He opens the call saying, “An air attack against North America may be in progress.” He mentions reports of a crash into the opposite side of the Pentagon, and requests that Defense Secretary Rumsfeld be added to the conference. [9/11 Commission, 6/17/2004 ; 9/11 Commission, 6/17/2004 ] Rumsfeld has a crucial role to play in coordinating the military response to an attack on the US. According to journalist and author Andrew Cockburn, since the Cold War, “In an age when an enemy attack might allow only a few minutes for detection and reaction, control of American military power became vested in the National Command Authority, which consists of the president and the secretary of defense. Collectively, the NCA is the ultimate source of military orders, uniquely empowered, among other things, to order the use of nuclear weapons. In time of war, therefore, Rumsfeld was effectively the president’s partner, the direct link to the fighting forces, and all orders had to go through him. Such orders were supposed to be transmitted from… the National Military Command Center.” Cockburn adds that the NMCC is “the operational center for any and every crisis, from nuclear war to hijacked airliners.” Yet, rather than join the NMCC conference, Rumsfeld has already gone out of the Pentagon to see the crash site, without telling any of his command staff where he was going, and remains out of contact for some time (see Between 9:38 a.m. and 10:00 a.m. September 11, 2001). Therefore, a few minutes after Leidig makes his request, Rumsfeld’s office will report back that he is nowhere to be found. Cockburn concludes, “The chain of command was broken.” [Cockburn, 2007, pp. 4-5; Democracy Now!, 3/7/2007] It is unknown whether Rumsfeld has a cell phone or pager on him, and if so, why he cannot be reached.
