Defense Secretary Donald Rumsfeld, Deputy Defense Secretary Paul Wolfowitz, Representatives Christopher Cox (R-CA) and John Mica (R-FL), and numerous others are meeting in Rumsfeld’s private Pentagon dining room, discussing missile defense (see (8:00 a.m.-8:50 a.m.) September 11, 2001). Rumsfeld later recalls, “I had said at an eight o’clock breakfast that sometime in the next two, four, six, eight, ten, twelve months there would be an event that would occur in the world that would be sufficiently shocking that it would remind people again how important it is to have a strong healthy Defense Department that contributes to—that underpins peace and stability in our world.” [US Department of Defense, 12/5/2001] Wolfowitz recalls, “And we commented to them that based on what Rumsfeld and I had both seen and worked on the Ballistic Missile Threat Commission, that we were probably in for some nasty surprises over the next ten years.” [Vanity Fair, 5/9/2003] According to Mica, “the subject of the conversation Donald Rumsfeld was interested in was, the military had been downsized during the ‘90s since the fall of the Berlin Wall. And what we were going to do about [the] situation if we had another—the word [Rumsfeld] used was ‘incident.‘… And he was trying to make certain that we were prepared for something that we might not expect.” [US Congress. House. Oversight and Government Reform Committee, 8/1/2007] There are confused accounts that Rumsfeld says, “I’ve been around the block a few times. There will be another event,” just before the Pentagon is hit by Flight 77 (see (Before 9:37 a.m.) September 11, 2001), but such comments may have been made around this time instead. Shortly afterwards, someone walks in with a note informing Rumsfeld that a plane has just hit the WTC (see Shortly After 8:46 a.m. September 11, 2001). [US Department of Defense, 12/5/2001; 9/11 Commission, 3/23/2004] Mica later comments, “[L]ittle did we know that within a few minutes of the end of our conversation and actually at the end of our breakfast, that our world would change and that incident that we talked about would be happening.” [US Department of Defense, 9/10/2004]
Shortly After 8:46 a.m. September 11, 2001: Defense Secretary Rumsfeld Learns of First WTC Attack
Larry Di Rita, a special assistant to Defense Secretary Donald Rumsfeld, has sent a note to Rumsfeld to inform him of the first plane hitting the World Trade Center. Although some initial reports suggest the WTC may have been hit by just a small plane, according to Victoria Clarke, the assistant secretary of defense for public affairs, “Even in the accidental crash scenario, the military might be involved in some way. Rumsfeld needed to know.” Rumsfeld, who is currently hosting a breakfast meeting with several members of Congress (see (8:00 a.m.-8:50 a.m.) September 11, 2001), later acknowledges having received this note. Yet apparently he does nothing in response. He recalls, “Everyone assumed it was an accident, the way it was described.” He says only that “we adjourned the meeting, and I went in to get my CIA briefing.” [US Department of Defense, 12/5/2001; 9/11 Commission, 3/23/2004; Clarke, 2006, pp. 217-218; Vogel, 2007, pp. 428]
9:03 a.m. September 11, 2001: Fighters Do Not Have Shootdown Authority
A fighter pilot flying from Otis Air Base toward New York City later notes that it wouldn’t have mattered if he caught up with Flight 175, because only President Bush could order a shootdown, and Bush is at a public event at the time. [Cape Cod Times, 8/21/2002]
“Only the president has the authority to order a civilian aircraft shot down,” according to a 1999 CNN report. [CNN, 10/26/1999] In fact, by 9/11, Defense Secretary Rumsfeld also has the authority to order a shootdown, but he is not responding to the crisis at this time. [New York Observer, 6/20/2004] Furthermore, NORAD Commander Larry Arnold later states that on 9/11, “I have the authority in case of an emergency to declare a target hostile and shoot it down under an emergency condition.” [Filson, 2003, pp. 75]
Shortly After 9:03 a.m. September 11, 2001: Defense Secretary Rumsfeld Receives His Intelligence Briefing, despite Being Aware of the Crisis
Secretary of Defense Donald Rumsfeld goes ahead with his daily intelligence briefing in his office at the Pentagon, even though Denny Watson, his CIA briefer, urges him to cancel it and respond to the terrorist attacks. [Rumsfeld, 2011, pp. 335; Priess, 2016, pp. 244] Rumsfeld has just been in a meeting in his private dining room that was attended by several members of Congress (see (8:00 a.m.-8:50 a.m.) September 11, 2001). During it, he was informed that a plane had crashed into the World Trade Center (see Shortly After 8:46 a.m. September 11, 2001). [Associated Press, 9/12/2001; US Department of Defense, 12/5/2001; 9/11 Commission, 3/23/2004] He assumed the crash was an accident. [Vogel, 2007, pp. 428; Rumsfeld, 2011, pp. 335]
Rumsfeld Went to His Office for His Intelligence Briefing – After the meeting ended, apparently around 9:00 a.m., he returned to his office to receive his intelligence briefing. [Historical Office, Office of the Secretary of Defense, 7/18/2002 
; 9/11 Commission, 7/24/2004, pp. 37] Rumsfeld receives an intelligence briefing from Watson each morning, similar to the intelligence briefing provided to the president each day. The briefings usually last at least half an hour. [Rumsfeld, 2011, pp. 335; Priess, 2016, pp. 243] The briefing today is scheduled to run from 9:00 a.m. to 9:30 a.m. [US Department of Defense, 8/12/2002]
CIA Briefer Learned of the Crashes from TV – Watson, meanwhile, recently arrived at the Pentagon and learned about the crashes at the WTC. After she entered the building, she noticed people staring at a television, which showed the North Tower burning after being hit by a plane. She then went to the anteroom of Rumsfeld’s office, where she saw the second hijacked plane crashing into the WTC live on television (see 9:03 a.m. September 11, 2001). She immediately called the operations center at CIA headquarters to see if she could find out more about what was happening. She was told only that there were 50 planes still airborne that were unaccounted for.
Rumsfeld Refuses to Cancel the Briefing – Rumsfeld then calls Watson into his office. Assuming the briefing will be suspended due to what has happened in New York, the CIA analyst hasn’t even opened her briefcase to pull out her copy of the President’s Daily Brief (PDB). “Sir, you just need to cancel this,” she says to Rumsfeld as she enters the office. “You’ve got more important things to do,” she adds. Rumsfeld, however, wants to go ahead with the briefing. “No, no, we’re going to do this,” he says. Watson then sits down and tells Rumsfeld what she learned from the CIA’s operations center, but the secretary of defense simply nods his head and starts flipping through the PDB. [Priess, 2016, pp. 244] The PDB apparently contains no remarkable information today. “As we reviewed the threat reports from around the world, September 11 seemed to be no more or less different than any other day,” Rumsfeld will later comment. [Rumsfeld, 2011, pp. 336]
Rumsfeld Will Be Receiving the Briefing When the Pentagon Is Hit – Vice Admiral Edmund Giambastiani Jr., Rumsfeld’s senior military assistant, will come into the office around this time and tell the secretary of defense about the second crash at the WTC (see (Shortly After 9:03 a.m.) September 11, 2001). [Historical Office, Office of the Secretary of Defense, 7/18/2002 ; US Department of Defense, 8/12/2002] Two of Rumsfeld’s aides will also come to the office and, like Watson, try, unsuccessfully, to persuade Rumsfeld to cancel his schedule so he can respond to the attacks (see a904rumsfeldrefuses). [Clarke, 2006, pp. 218-219; Priess, 2016, pp. 244] Rumsfeld will be in his office with Watson, still receiving his intelligence briefing, at 9:37 a.m., when the Pentagon is attacked (see 9:37 a.m. September 11, 2001). [Goldberg et al., 2007, pp. 130; Vogel, 2007, pp. 438-439]
Between 9:04 a.m. and 9:36 a.m. September 11, 2001: Defense Secretary Rumsfeld Ignores His Aides’ Attempts to Get Him to Respond to the Attacks
Victoria Clarke, the assistant secretary of defense for public affairs, and Larry Di Rita, a special assistant to the secretary of defense, try to persuade Secretary of Defense Donald Rumsfeld to cancel his schedule so he can respond to the terrorist attacks, but Rumsfeld refuses to do so and continues with a routine intelligence briefing. [Clarke, 2006, pp. 218-219; Priess, 2016, pp. 244] Rumsfeld is in his office at the Pentagon with Denny Watson, a CIA analyst, who is giving him his daily intelligence briefing. He is aware of the two crashes at the World Trade Center (see Shortly After 8:46 a.m. September 11, 2001 and (Shortly After 9:03 a.m.) September 11, 2001). [9/11 Commission, 3/23/2004; 9/11 Commission, 7/24/2004, pp. 37; Rumsfeld, 2011, pp. 334-335]
Aides Go to Talk with Rumsfeld about His Response to the Crisis – Clarke and Di Rita, meanwhile, learned of the attacks on the WTC from seeing the coverage of them on television. After the second crash, Clarke headed to Di Rita’s office, which is down the hallway from Rumsfeld’s office. There, she and Di Rita discussed “what had to be done right away in terms of the secretary [of defense],” Clarke will later recall. The two aides then headed together to see Rumsfeld, to talk with him about “the kinds of things he needed to do in response to this [crisis].”
Aides Tell Rumsfeld What They Know about the Attacks – After they enter Rumsfeld’s office, Clarke and Di Rita tell the secretary of defense what is happening and what they know about the attacks. They say the Executive Support Center (ESC) “is going to start getting spun up.” [Historical Office, Office of the Secretary of Defense, 6/27/2002 ; Historical Office, Office of the Secretary of Defense, 7/2/2002 ; Clarke, 2006, pp. 216-219] The ESC is a secure communications hub with a video teleconference facility, located on the third floor of the Pentagon. [Historical Office, Office of the Secretary of Defense, 6/27/2002 ; Vogel, 2007, pp. 440] It is “the place where the building’s top leadership goes to coordinate military operations during national emergencies,” according to Clarke.
Rumsfeld Refuses to Change His Schedule – Clarke and Di Rita also advise Rumsfeld to cancel his appointments for the rest of the day. “Sir, I think your entire schedule is going to be different today,” Di Rita says. But Rumsfeld refuses to do so. “No! If I cancel my day, the terrorists have won,” he says. Undeterred, the two aides pull out a copy of Rumsfeld’s agenda for the day and go through it point by point, explaining to the secretary of defense why each item could be canceled. However, Rumsfeld’s response is to look at the television on the desk and watch the coverage of the attacks on the WTC. [Clarke, 2006, pp. 219; Priess, 2016, pp. 244] Rumsfeld “wanted to make a few phone calls” at this time, Clarke will tell one interviewer. [WBZ Radio 1030 (Boston), 9/15/2001]
Aides Go to the Support Center to Respond to the Attacks – Rumsfeld tells the two aides to go to the ESC and wait for him there. Clarke and Di Rita therefore leave the office and head to the ESC (see Shortly After 9:03 a.m. September 11, 2001). They will be in the ESC at 9:37 a.m., when the Pentagon is attacked (see 9:37 a.m. September 11, 2001). [Historical Office, Office of the Secretary of Defense, 7/2/2002 ; Clarke, 2006, pp. 219-220] Rumsfeld, meanwhile, continues skimming through the copy of the President’s Daily Brief that Watson brought him. [Priess, 2016, pp. 244] He will still be in his office receiving his intelligence briefing when the Pentagon is attacked (see 9:37 a.m. September 11, 2001). [Goldberg et al., 2007, pp. 130; Vogel, 2007, pp. 438-439]
Shortly After 9:03 a.m. September 11, 2001: Defense Secretary Rumsfeld Is Told of the Second Crash but Continues with a Routine Briefing
Secretary of Defense Donald Rumsfeld is told that a second plane has crashed into the World Trade Center by Vice Admiral Edmund Giambastiani Jr., his senior military assistant, but continues with a routine intelligence briefing. [Historical Office, Office of the Secretary of Defense, 7/18/2002 ; 9/11 Commission, 7/24/2004, pp. 37; Goldberg et al., 2007, pp. 130] Rumsfeld learned about the first crash at the WTC during a meeting in his private dining room at the Pentagon, but he assumed it was an accident (see Shortly After 8:46 a.m. September 11, 2001). [Vogel, 2007, pp. 428; Rumsfeld, 2011, pp. 334-335] After the meeting ended he returned to his office to receive his daily intelligence briefing. [9/11 Commission, 7/24/2004, pp. 37] Giambastiani was at the meeting in Rumsfeld’s private dining room and similarly returned to his office when it ended—apparently around 9:00 a.m.—to continue with his regular work. The television in his office was on and so he saw the second hijacked plane crashing into the WTC live, at 9:03 a.m. (see 9:03 a.m. September 11, 2001). He apparently realized right away that the incident was a terrorist attack. “Then there was absolutely no doubt in anybody’s mind that it was not a random event or an accident,” he will later comment, adding, “There was absolutely no doubt in my mind.” He goes to tell Rumsfeld what has happened. “I went in and informed the secretary [of defense],” he will say. [Historical Office, Office of the Secretary of Defense, 7/18/2002 ] “Someone came in and said that another plane had hit a different tower of the World Trade Center,” Rumsfeld will recall. [US Department of Defense, 8/12/2002] The two men apparently now realize the seriousness of the crisis. “When the second plane hit the World Trade Center, it became clear that it was more than an accident,” Rumsfeld will comment. [CBS, 9/8/2002] “We knew there was a problem here,” Giambastiani will say. [Historical Office, Office of the Secretary of Defense, 7/18/2002 ] However, Rumsfeld continues with his intelligence briefing. “[H]e resumed the briefing while awaiting more information,” the 9/11 Commission Report will state. He will still be in his office receiving the briefing at 9:37 a.m., when the Pentagon is attacked (see 9:37 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 37; Vogel, 2007, pp. 438-439]
9:05 a.m. September 11, 2001: National Security Adviser Rice Tries to Assemble National Security Team, but Cannot Reach Key Officials
National Security Adviser Condoleezza Rice tries to gather together the principals of the National Security Council (NSC), but is unable to get in touch with key officials. Rice realized the US was under terrorist attack during a staff meeting, when her assistant informed her of the second plane striking the World Trade Center (see (9:04 a.m.) September 11, 2001). She had then headed to the White House Situation Room’s operations center. [Newsweek, 12/30/2001; Bumiller, 2007, pp. xii] Here she intends to assemble the principals of the NSC for a crisis meeting. [O, the Oprah Magazine, 2/1/2002] Along with the national security adviser, the principal members of the NSC are the president, the vice president, the secretary of state, the secretary of the treasury, and the secretary of defense; additionally, the CIA director and the chairman of the Joint Chiefs of Staff are statutory advisers to the NSC. [US President, 2/13/2001; Felix, 2002, pp. 226] However, Rice remembers that Secretary of State Colin Powell is currently away in Peru (see (8:30 a.m.) September 11, 2001). [MSNBC, 9/11/2002] Treasury Secretary Paul O’Neill is away in Japan. [US Department of the Treasury, 11/29/2001; US Department of the Treasury, 1/23/2002] And Chairman of the Joint Chiefs of Staff Henry Shelton is on his way to Europe for a NATO meeting there. [CNN, 10/1/2001] Rice tries calling Defense Secretary Donald Rumsfeld, who is in his office at the Pentagon (see (Shortly After 9:03 a.m.) September 11, 2001), but cannot reach him. [PBS Frontline, 7/12/2002; Clarke, 2006, pp. 218-219; Cockburn, 2007, pp. 1] She is also unable to get a call through to CIA Director George Tenet. [Bumiller, 2007, pp. xii] (Tenet will later claim that, around this time, he is having trouble using his secure phone while being driven out to CIA headquarters (see (8:55 a.m.-9:15 a.m.) September 11, 2001). [Tenet, 2007, pp. 161-162] ) Also around this time, in the Secure Video Conferencing Center just off the main floor of the Situation Room, counterterrorism “tsar” Richard Clarke is trying to convene a video teleconference with other top officials (see (9:10 a.m.) September 11, 2001). [Bumiller, 2007, pp. xii]
9:10 a.m. September 11, 2001: Counterterrorism ‘Tsar’ Clarke Directs Crisis Response through Video Conference with Top Officials
Around this time, according to his own account, counterterrorism “tsar” Richard Clarke reaches the Secure Video Conferencing Center just off the main floor of the Situation Room in the West Wing of the White House. From there, he directs the response to the 9/11 attacks and stays in contact with other top officials through video links. Clarke claims that on video he can see Defense Secretary Donald Rumsfeld, CIA Director George Tenet, FBI Director Robert Mueller, FAA Administrator Jane Garvey, Deputy Attorney General Larry Thompson (filling in for the traveling Attorney General John Ashcroft), Deputy Secretary of State Richard Armitage (filling in for the traveling Secretary of State Colin Powell), and Vice Chairman of the Joint Chiefs of Staff Richard Myers (filling in for the traveling Chairman Henry Shelton). National Security Adviser Condoleezza Rice is with Clarke, but she lets him run the crisis response, deferring to his longer experience on terrorism matters. Clarke is also told by an aide, “We’re on the line with NORAD, on an air threat conference call.” [Clarke, 2004, pp. 2-4; Australian, 3/27/2004] According to the 9/11 Commission, logs indicate that Clarke’s video teleconference only begins at 9:25 a.m. (see 9:25 a.m. September 11, 2001), which is later than Clarke suggests, and CIA and FAA representatives only join it at 9:40 a.m. [9/11 Commission, 7/24/2004, pp. 36 and 462] Other accounts claim that, rather than being involved in Clarke’s teleconference at this time, Donald Rumsfeld is still in his office waiting for his intelligence briefing (see (Shortly After 9:03 a.m.) September 11, 2001), and Richard Myers is in a meeting on Capitol Hill (see (After 9:03 a.m.) September 11, 2001). [Armed Forces Radio And Television Service, 10/17/2001; Clarke, 2006, pp. 218-219] The 9/11 Commission claims that, “While important,” Clarke’s conference has “no immediate effect on the emergency defense efforts.” [9/11 Commission, 6/17/2004 ] Yet, as the Washington Post puts it, “everyone seems to agree” Clarke is the chief crisis manager on 9/11. [Washington Post, 3/28/2004] Even Clarke’s later opponent, National Security Adviser Rice, calls him 9/11’s “crisis management guy.” [United Press International, 4/9/2004] The conference is where the government’s emergency defense efforts are concentrated.
9:33 a.m. September 11, 2001: FAA Notifies Video Conference United 93 Is Suspected Hijack
FAA Administrator Jane Garvey notifies the video conference chaired by counterterrorism “tsar” Richard Clarke that all aircraft have been ordered to land at the nearest field and reads a list of potential hijacks including Delta 1989 and United 93. [Clarke, 2004, pp. 5] Although, according to Clarke’s account, both General Richard Myers and Secretary of Defense Donald Rumsfeld are present at the conference at this point, the 9/11 Commission will later claim that the military was not notified about the hijacking of United 93 until over half an hour later (see 10:03 a.m. September 11, 2001).
9:35 a.m.-9:36 a.m. September 11, 2001: Several Witnesses See a Helicopter near the Pentagon
A number of witnesses see a helicopter flying near the Pentagon in the minutes before the attack there. 
Jeffrey Mark Parsons, an assistant chief patrol agent with the United States Border Patrol, sees a blue and white helicopter that appears as if it is coming in to land, from a window on the 17th floor of the hotel he is staying at, near the Pentagon. Parsons will later recall that two or three minutes before the Pentagon attack occurs: “I saw [the helicopter] circle… between the hotel and the Pentagon, going toward the landing pad [at the Pentagon] where that airliner ultimately hit. And I thought that he landed on the pad.” Parsons will say the helicopter flies in at “a weird angle,” and recall that he has been staying at the Marriott Residence Inn in Arlington for almost a month, but has “never seen a helicopter approach the Pentagon from that direction before.” He will recognize the helicopter as a Huey because he has flown Hueys and knows they make “a very distinct sound.” According to John Darrell Sherwood, a Navy historian who interviews Parsons about the incident, the helicopter belongs to the US Park Police and has been instructed to intercept the aircraft that subsequently hits the Pentagon (see Shortly Before 9:35 a.m. September 11, 2001). [US Naval Historical Center, 12/13/2001; Goldberg et al., 2007, pp. 258] A senior Air Force officer who is somewhere outside the Pentagon also sees a helicopter circling the Pentagon around this time, although he believes it to be a US military helicopter. Shortly after the Pentagon attack, the unnamed officer will tell a CNN reporter that the helicopter “disappeared behind the building where the helicopter landing zone is… and he then saw [a] fireball go into the sky” when the Pentagon is hit. [CNN, 9/11/2001] Jennifer Reichert, who is stuck in traffic on Route 27 in front of the Pentagon, will describe that just before the attack, “A helicopter takes off from the heliport at the Pentagon.” She will add: “Minutes—maybe seconds—later, I hear it: American Airlines Flight 77 screams toward the Pentagon. The explosion [of the crash] shakes my car.” [Washington Post, 9/5/2002] Secretary of Defense Donald Rumsfeld and Denny Watson, his CIA briefer, who are in Rumsfeld’s office at the Pentagon, see a helicopter flying very close to the building, outside the window of the office, and then pulling away just before the building is attacked (see Shortly Before 9:37 a.m. September 11, 2001). [Priess, 2016, pp. 244-245]
Perhaps due to the presence of this helicopter in the area, some people will initially think the attack on the Pentagon involves a helicopter hitting the building. Captain William Durm, the commander of the Pentagon’s Triservice Dental Clinic, will head to the building’s center courtyard shortly after the Pentagon is hit. Someone there will tell him a helicopter has hit the other side of the building. [Marble and Milhiser, 9/2004, pp. 11] Some early news reports will suggest a helicopter crashed into the Pentagon. [Thomas Crosbie Media, 9/11/2001; Poynter Institute, 9/2/2002] One report will claim that “one aircraft and a helicopter have crashed into the Pentagon.” [Airline Industry Information, 9/11/2001] Vice President Dick Cheney will tell NBC’s Meet the Press that “the first reports on the Pentagon attack suggested a helicopter” hit the building. [Meet the Press, 9/16/2001] The Guardian will report that one witness claims the explosion that occurs when the Pentagon is hit blows up a helicopter circling overhead. [Guardian, 9/12/2001] New York Times columnist William Safire will report that, at approximately this time, Cheney is told that either another plane or “a helicopter loaded with explosives” is heading for the White House. [New York Times, 9/13/2001]
