Those in the National Military Command Center (NMCC) within the Pentagon see the second plane hitting the World Trade Center live on television. According to Dan Mangino, an operations officer at the center, the staff there had thought the first WTC crash was a “terrible accident,” but after seeing the second one, “we knew immediately that it was a terrorist attack.” The American Forces Press Service later reports, “Personnel in the center shifted into hyperdrive.… Phones in the center began ringing off the hook.” Mangino says he initiates “the process to stand up a working group in advance of the direction that would come down later.” One of his deputies is responsible for this process. Yet, despite this supposed urgency, Mangino later recalls that he “knew he would have little time in the days ahead, so he quickly ran to the concourse to get some money out of an automated teller machine.” He will not arrive back at the NMCC until after the Pentagon is hit. [American Forces Press Service, 9/7/2006] Brigadier General Montague Winfield had earlier on allowed a colleague to temporarily take over from him as the NMCC’s deputy director for operations (see 8:30 a.m. September 11, 2001). Yet, despite the obvious emergency now taking place, he does not retake charge of the center until more than an hour later, at around 10:15-10:30 a.m. (see (Shortly After 9:03 a.m.) September 11, 2001). [9/11 Commission, 6/17/2004] Furthermore, according to the 9/11 Commission, the NMCC does not begin a “significant event” conference call in response to the attacks until 9:29 a.m., which is 26 minutes after the South Tower is hit (see 9:29 a.m.-9:34 a.m. September 11, 2001).

; 9/11 Commission, 7/24/2004, pp. 37]
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.
Shortly After 9:03 a.m. September 11, 2001: Military Officers at FAA Command Center Contact NMCC about Response to Attacks
Two officers in the Air Traffic Services Cell (ATSC)—a small office at the FAA’s Command Center in Herndon, Virginia, manned by military reservists—contact the National Military Command Center (NMCC) at the Pentagon, to ask about military assistance in response to the terrorist attacks. [US Air Force, 9/11/2001; Aviation Week and Space Technology, 6/10/2002; 9/11 Commission, 4/14/2004]
Military Leaders ‘in a Meeting to Determine Their Response’ – Apparently shortly after the south World Trade Center tower is hit at 9:03 a.m., Ben Sliney, the national operations manager at the Command Center, asks the ATSC for a military response to the ongoing events (see 9:06 a.m. and After September 11, 2001). Therefore, Lieutenant Colonel Michael-Anne Cherry, one of the three officers on duty in the ATSC, calls the NMCC. However, according to a chronology of the ATSC’s actions on this day, Cherry is told that “senior leaders” at the NMCC are “in a meeting to determine their response” to the attacks, and will call back.
Second Officer Calls NMCC, Told Fighters Have Been Launched – Then, at around 9:08 a.m., Sliney talks to another of the officers on duty in the ATSC, Colonel John Czabaranek, and asks if fighter jets have been launched toward New York. [US Air Force, 9/11/2001; 9/11 Commission, 4/14/2004] Two F-15s have already taken off from Otis Air National Guard Base, Massachusetts, toward the New York area (see 8:46 a.m. September 11, 2001), but, according to the 9/11 Commission, “Lacking a target,” these fighters have been “vectored toward military-controlled airspace off the Long Island coast” (see (8:53 a.m.-9:05 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] In response to Sliney’s inquiry, Czabaranek calls the NMCC. The NMCC indicates that it is aware of the request for fighter support, and says aircraft have been scrambled from Otis Air Base. Czabaranek passes this information on to Sliney, telling him that fighters are en route.
ATSC’s Secure Phones Initially Not Working – According to the chronology of the ATSC’s actions, the unit’s secure phones do not work for an incoming call from the NMCC that is apparently made shortly after 9:03 a.m. The ATSC’s keys for its secure phones are recalibrated, and the phones then “worked fine.” [US Air Force, 9/11/2001; 9/11 Commission, 4/14/2004]
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]
After 9:20 a.m. September 11, 2001: FAA Administrator Frustrated that Military Is Not Involved in Teleconference
At 9:20 a.m. (or earlier, according to some accounts), the FAA set up a hijacking teleconference with several agencies (see (9:20 a.m.) September 11, 2001). FAA records indicate that the National Military Command Center within the Pentagon was included in the communication network “no later than 9:20 a.m.” [9/11 Commission, 6/17/2004 ] Yet at some point later in the morning, Acting FAA Deputy Administrator Monte Belger becomes aware that the military is not involved in the teleconference in any meaningful way. Presumably referring to tape recordings of the FAA headquarters, 9/11 Commissioner Jamie Gorelick will later say to Belger, “We heard some rather colorful language came from your mouth at that point.” The absence of the NMCC from the teleconference is unusual. Belger says, “I’ve lived through dozens of hijackings in my 30-year FAA career… and [the NMCC] were always there. They were always on the net, and were always listening in with everybody else.” He adds, “The most frustrating after-the-fact scenario for me to understand is to explain… the communication link on that morning between the FAA operations center and the NMCC.… I know how it’s supposed to work, but… it’s still a little frustrating for me to understand how it actually did work on that day.” [9/11 Commission, 6/17/2004; 9/11 Commission, 7/24/2004, pp. 36]
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]
9:36 a.m.-10:06 a.m. September 11, 2001: Military Claims It Is Tracking Flight 93 and Ready to Shoot It Down; 9/11 Commission Says Otherwise
According to the later claims of several senior officials, the US military is tracking Flight 93 as it heads east and is ready to shoot it down if necessary. 
According to Brigadier General Montague Winfield, the Pentagon’s National Military Command Center (NMCC) has “received the report from the FAA that Flight 93 had turned off its transponder, had turned, and was now heading towards Washington, DC.” Winfield will add, “The decision was made to try to go intercept Flight 93.” [ABC News, 9/11/2002] General Richard Myers, the acting chairman of the Joint Chiefs of Staff, will write that in the NMCC, “We learned that there was apparently a fourth hijacked aircraft, United Airlines Flight 93 out of Newark, bound nonstop for San Francisco. Like the other planes, it had switched off its transponder, making it much harder if not impossible to track on ground radar.” [Myers and McConnell, 2009, pp. 152] Major General Larry Arnold, the commander of the Continental United States NORAD Region, will say, “I was personally anxious to see what 93 was going to do, and our intent was to intercept it.” Three fighters have taken off from Langley Air Force Base in Virginia (see (9:25 a.m.-9:30 a.m.) September 11, 2001). According to Arnold, “we launched the aircraft out of Langley to put them over top of Washington, DC, not in response to American Airline 77, but really to put them in position in case United 93 were to head that way.” [9/11 Commission, 5/23/2003] He says, “as we discussed it in the conference call, we decided not to move fighters toward 93 until it was closer because there could have been other aircraft coming in,” but adds, “I had every intention of shooting down United 93 if it continued to progress toward Washington, DC… whether we had authority or not.” [Filson, 2003, pp. 73] Colonel Robert Marr, the battle commander at NORAD’s Northeast Air Defense Sector (NEADS), is reportedly “focused on United Flight 93, headed straight toward Washington.” He will concur with Arnold, saying: “United Airlines Flight 93 would not have hit Washington, DC. He would have been engaged and shot down before he got there.” [Filson, 2003, pp. 73] Marr and Arnold will both say they were tracking Flight 93 even earlier on, while it was still heading west (see Shortly Before 9:36 a.m. September 11, 2001).
Yet, contradicting these claims, the 9/11 Commission will conclude that the military only learns about Flight 93 around the time it crashes. It says the NMCC learns of the hijacking at 10:03 a.m. (see 10:03 a.m. September 11, 2001). Based upon official records, including recordings of the NEADS operations floor, it says NEADS never follows Flight 93 on radar and is first alerted to it at 10:07 a.m. (see 10:05 a.m.-10:08 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 30-31, 34 and 42; Washington Post, 4/30/2006; Vanity Fair, 8/1/2006]
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 ]
Shortly After 9:37 a.m. September 11, 2001: Officer in Pentagon Command Center Only Learns from TV that Pentagon Has Been Hit
The Pentagon’s National Military Command Center (NMCC) is located on the other side of the building to where it is hit. Therefore, when the attack on the Pentagon occurs, those inside it supposedly do not feel the impact. [CNN, 9/4/2002] According to Newsweek, the NMCC has been called “the primary nerve system” of the Pentagon, from where “commanders can monitor and communicate with American forces around the world.” [Newsweek, 9/28/2001] A military instruction for dealing with hijacked aircraft describes it as “the focal point within Department of Defense for providing assistance” in response to hijackings. [US Department of Defense, 6/1/2001 ] But supposedly NMCC personnel do not initially realize the Pentagon has been attacked. Steve Hahn, an operations officer at the center, later says, “I didn’t know [the Pentagon had been hit] until I heard the news report on television.” [American Forces Press Service, 9/7/2006] Yet an article in the New York Times later claims, “During the hour or so that American Airlines Flight 77 was under the control of hijackers, up to the moment it struck the west side of the Pentagon, military officials in [the NMCC] were urgently talking to law enforcement and air traffic control officials about what to do” (see (Shortly After 8:51 a.m.) September 11, 2001). [New York Times, 9/15/2001] Furthermore, at about 8:50 a.m. according to the FAA, or 9:20 a.m. according to the 9/11 Commission, the FAA had established several phone bridges linking key players, including the NMCC (see (8:50 a.m.) September 11, 2001) (see (9:20 a.m.) September 11, 2001). The FAA states that it shares “real-time information on the phone bridges,” which includes “actions being taken by all the flights of interest, including Flight 77.” [9/11 Commission, 5/23/2003; 9/11 Commission, 7/24/2004, pp. 36] Why NMCC personnel do not therefore know immediately that the Pentagon has been hit is unclear. Also around this time, Officer Aubrey Davis of the Pentagon police is outside Donald Rumsfeld’s office. He hears what he later describes as “an incredibly loud ‘boom,’” when the Pentagon is struck (see 9:38 a.m. September 11, 2001). Yet no mention is made of anyone in the NMCC hearing this “boom,” even though the center is located only around 200 feet from where Davis is standing. [WBZ Radio 1030 (Boston), 9/15/2001; Cockburn, 2007, pp. 1] Dan Mangino, an operations officer in the NMCC, went out earlier to withdraw some money from a cash machine (see 9:03 a.m. September 11, 2001), and rushes back to the center after the Pentagon is hit. He finds the people in it are very calm. He says, “There was no panic, no raised voices. We train for emergencies all the time, and that training took over.” [American Forces Press Service, 9/7/2006]
