Key Events of 9/11 (74) - Page 3

According to the 9/11 Commission, NEADS contacts Washington flight control to ask about Flight 11. A manager there happens to mention, “We’re looking—we also lost American 77.” The commission claims, “This was the first notice to the military that American 77 was missing, and it had come by chance.… No one at FAA Command Center or headquarters ever asked for military assistance with American 77.” [9/11 Commission, 6/17/2004] Yet, 38 minutes earlier, flight controllers determined Flight 77 was off course, out of radio contact, and had no transponder signal (see 8:56 a.m. September 11, 2001). They’d warned American Airlines headquarters within minutes. By some accounts, this is the first time NORAD is told about Flight 77, but other accounts have them warned around 9:25 a.m.

Vice President Dick Cheney is taken by the Secret Service from his office to an underground tunnel leading to the Presidential Emergency Operations Center (PEOC) below the White House around this time, according to some accounts, including the 9/11 Commission Report, although other accounts will suggest he was evacuated from his office about half an hour earlier. [United States Secret Service, 11/17/2001; Newsweek, 12/30/2001; 9/11 Commission, 7/24/2004, pp. 39-40; Hayes, 2007, pp. 333, 335] Cheney, who is in his office in the West Wing of the White House, is aware of the two plane crashes in New York and realizes this is a terrorist attack. He is now “watching developments on the television,” he will later recall, and starting “to get organized to figure out what to do.” [Meet the Press, 9/16/2001; Hayes, 2007, pp. 330-331] The Secret Service was informed that an unidentified aircraft was heading toward the White House at around 9:33 a.m. (see 9:33 a.m. September 11, 2001 and (9:33 a.m.) September 11, 2001). Concern about this aircraft prompted it to order the evacuation of Cheney “just before 9:36,” according to the 9/11 Commission Report (see 9:35 a.m. September 11, 2001). [Federal Aviation Administration, 9/17/2001; 9/11 Commission, 7/24/2004, pp. 39]

Armed Agents Enter Cheney’s Office - Four or five Secret Service agents carrying submachine guns therefore enter Cheney’s office, according to Washington Post reporter Barton Gellman. One of them, Special Agent James Scott, pushes through the group of government officials who are gathered around Cheney (see (Shortly After 9:03 a.m.) September 11, 2001) and tells the vice president, “Sir, we need to move you—now.” Cheney nods, indicating that he will respond to the agent in a moment, and then turns to say something to another person. But Scott brings down the flat of his hand sharply on Cheney’s desk and commands, “Now!” [Gellman, 2008, pp. 114-115]

Cheney Propelled out of His Office - Scott then puts his hand on Cheney’s shoulder, grabs the vice president by the back of his belt, and moves him out the door. [Hayes, 2007, pp. 333] Cheney will comment that Secret Service agents “practice this, I’m sure, because… whether you wanted to move or not, you’re going. They don’t exactly pick you up and carry you. It’s more like they propel you forward.” [White House, 11/19/2001] As the Secret Service agents take Cheney through his outer office, the vice president manages to grab the latest issue of The Economist off a table. “I’m always carrying something in case I get hung up someplace,” he will explain. “I’ve got to have something to read.” [Newsweek, 12/30/2001; Hayes, 2007, pp. 333] Carrying the magazine but nothing more, Cheney is hurried down the hallway, past the Oval Office, and down into the basement of the White House. [White House, 11/19/2001]

Other Officials Left in Cheney’s Office - The officials who were with Cheney are left in his office. Mary Matalin, one of Cheney’s senior advisers, will recall: ”[S]peechwriter John McConnell and I were left behind in his office, staring at each other as if to say, ‘What are we, chopped liver?’ I think I actually said that.” [National Review, 9/8/2011] Cheney will arrive in the underground tunnel leading to the PEOC about a minute after he leaves his office (see 9:37 a.m. September 11, 2001). There he will learn that the Pentagon has been hit and talk over the phone with the president (see 9:45 a.m.-9:56 a.m. September 11, 2001) before heading into the PEOC (see 9:58 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 40; Hayes, 2007, pp. 335-336] However, according to some accounts, Cheney was evacuated from his office a significant time earlier on, around 9:03 a.m., when the second plane crashed in New York (see (Shortly After 9:03 a.m.) September 11, 2001). [New York Times, 9/13/2001; Daily Telegraph, 12/16/2001; ABC News, 9/14/2002; Clarke, 2004, pp. 1-2]

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, 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]

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]

Flight 77 crashes into the Pentagon. All 64 people on the plane are killed. A hundred-and-twenty-four people working in the building are killed, and a further victim will die in hospital several days later. Hijackers Hani Hanjour, Khalid Almihdhar, Majed Moqed, Nawaf Alhazmi, and Salem Alhazmi presumably are killed instantly. (Typically, they are not included in the death counts.) [CNN, 9/17/2001; North American Aerospace Defense Command, 9/18/2001; Guardian, 10/17/2001; Washington Post, 11/21/2001; USA Today, 8/12/2002; Associated Press, 8/21/2002; ABC News, 9/11/2002] Flight 77 hits the first floor of the Pentagon’s west wall. The impact and the resulting explosion heavily damage the building’s three outer rings. The path of destruction cuts through Army accounting offices on the outer E Ring, the Navy Command Center on the D Ring, and the Defense Intelligence Agency’s comptroller’s office on the C Ring. [Vogel, 2007, pp. 431 and 449] Flight 77 strikes the only side of the Pentagon that had recently been renovated—it was “within days of being totally [renovated].” [US Department of Defense, 9/15/2001] “It was the only area of the Pentagon with a sprinkler system, and it had been reconstructed with a web of steel columns and bars to withstand bomb blasts. The area struck by the plane also had blast-resistant windows—two inches thick and 2,500 pounds each—that stayed intact during the crash and fire. While perhaps, 4,500 people normally would have been working in the hardest-hit areas, because of the renovation work only about 800 were there.” More than 25,000 people work at the Pentagon. [Los Angeles Times, 9/16/2001] Furthermore, the plane hits an area that has no basement. As journalist Steve Vogel later points out, “If there had been one under the first floor, its occupants could easily have been trapped by fire and killed when the upper floors collapsed.” [Vogel, 2007, pp. 450]

Accounts differ as to how far from Washington the F-16 fighters scrambled from Langley are when Flight 77 crashes. The Langley, Virginia, base is 129 miles from Washington. NORAD originally claimed that, at the time of the crash, the fighters are 105 miles away, despite having taken off seven minutes earlier. [North American Aerospace Defense Command, 9/18/2001] The 9/11 Commission claims that at 9:36 a.m., NEADS discovers that Flight 77 is only a few miles from the White House and is dismayed to find the fighters have headed east over the ocean. They are ordered to Washington immediately, but are still about 150 miles away. This is farther away than the base from which they took off. [9/11 Commission, 6/17/2004] The F-16 pilot codenamed Honey (who is apparently Captain Craig Borgstrom) offers a different explanation. As previously mentioned, he says they are flying toward New York, when they see a black column of smoke coming from Washington, about 30 or 40 miles to the west. He is then asked over the radio by NEADS if he can confirm the Pentagon is burning. He confirms it. He says that the mission of the Langley pilots at this time is clear: to keep all airplanes away from Washington. The F-16s are then ordered to set up a defensive perimeter above Washington. [Longman, 2002, pp. 76; Filson, 2003, pp. 66; New York Observer, 2/15/2004] The maximum speed of an F-16 is 1,500 mph. [Associated Press, 6/16/2000] Had the fighters traveled straight to Washington at 1,300 mph, they would have reached Washington at least one minute before Flight 77. Furthermore, at the time the Pentagon is hit, according to Craig Borgstrom, he and the other Langley pilots are hearing a lot of chatter over their radios, but nothing about airliners crashing into buildings. He says they are “all three on different frequencies… and [are] getting orders from a lot of different people.” [Filson, 2003, pp. 66]

Within seconds of the Pentagon being hit, Defense Secretary Donald Rumsfeld rushed out of his office and headed toward the crash scene (see 9:38 a.m. September 11, 2001). According to Officer Aubrey Davis, who is currently accompanying Rumsfeld as his bodyguard, when they reach the site, “There were the flames, and bits of metal all around. The secretary picked up one of the pieces of metal. I was telling him he shouldn’t be interfering with a crime scene when he looked at some inscription on it and said, ‘American Airlines.‘” According to Rumsfeld, a person who’d seen the attack on the Pentagon informs him a plane had flown into it. Rumsfeld later recalls: “I saw people on the grass, and we just, we tried to put them in stretchers and then move them out across the grass towards the road and lifted them over a jersey wall so the people on that side could stick them into the ambulances. I was out there for a while, and then people started gathering, and we were able to get other people to do that, to hold IVs for people. There were people lying on the grass with clothes blown off and burns all over them.” [Parade Magazine, 10/12/2001; Cockburn, 2007, pp. 1-2] Versions of this story will appear elsewhere. [US Department of Defense, 12/5/2001; ABC News, 9/11/2002; Vanity Fair, 5/9/2003] Video footage confirms that Rumsfeld helps carry a stretcher at the crash scene. [CNN, 8/17/2002] One report will even describe him pulling budget analyst Paul Gonzales to safety from the burning wreckage. [Daily Telegraph, 9/16/2001] However, Gonzales later offers his own detailed recollections of pulling other people to safety, which fail to involve Rumsfeld in any way. [Washington Post, 3/11/2002] Assistant Secretary of Defense for Public Affairs Victoria Clarke will say Rumsfeld is gone from the building for “about half an hour.” [WBZ Radio 1030 (Boston), 9/15/2001] A Pentagon spokesperson has Rumsfeld helping at the crash site for “15 minutes or so.” [Reuters, 9/11/2001] Another account will claim he loads the wounded onto stretchers for 15 minutes. [Scripps Howard News Service, 9/11/2001] However, considering the time it would have taken to walk to the crash site—each side of the enormous Pentagon is the length of three football fields—journalist Andrew Cockburn later concludes that Rumsfeld could only have been at the crash scene for a brief period. [Cockburn, 2007, pp. 3] Rumsfeld reportedly heads back into the Pentagon at the urging of a security agent, though in an interview soon after 9/11 he will claim the decision to go back inside was his own, saying, “I decided I should be in [the building] figuring out what to do, because your brain begins to connect things, and there were enough people there to worry about that.” [Parade Magazine, 10/12/2001; Washington Post, 1/27/2002] He tells the 9/11 Commission, “I was back in the Pentagon with a crisis action team shortly before or after 10:00 a.m.” (see 10:00 a.m.-10:30 a.m. September 11, 2001). [9/11 Commission, 3/23/2004] While Rumsfeld is at the crash scene, others are frantically trying to get in touch with him but are unable to do so (see 9:38 a.m.-10:00 a.m. September 11, 2001).

Secretary of Defense Donald Rumsfeld heads for the crash site immediately after the Pentagon is hit. At the time of the attack, Rumsfeld is in his office proceeding with his regularly scheduled CIA briefing, despite being aware of the two attacks on the World Trade Center earlier on. Waiting outside his door is Officer Aubrey Davis of the Pentagon police, who is assigned to the defense secretary’s personal bodyguard and has come of his own initiative to move Rumsfeld to a better-protected location. According to Davis, there is “an incredibly loud ‘boom,’” as the Pentagon is struck. Just 15 or 20 seconds later, Rumsfeld walks out of his door looking composed, having already put on the jacket he normally discards when in his office. Davis informs him there is a report of an airplane hitting a section of the Pentagon known as the Mall. Rumsfeld sets off without saying anything or informing any of his command staff where he is going, and heads swiftly toward the Mall. Davis accompanies him, as does Rumsfeld’s other security guard Gilbert Oldach, his communications officer, and the deputy director of security for the secretary’s office. Finding no sign of damage at the Mall, Davis tells Rumsfeld, ”[N]ow we’re hearing it’s by the heliport,” which is along the next side of the building. Despite Davis’s protests that he should head back, Rumsfeld continues onward, and they go outside near where the crash occurred. [Cockburn, 2007, pp. 1-2; Goldberg et al., 2007, pp. 130; Democracy Now!, 3/7/2007] The Pentagon was hit on the opposite site of the huge building to Rumsfeld’s office. [Reuters, 9/11/2001] Assistant Secretary of Defense for Public Affairs Victoria Clarke will say that Rumsfeld is “one of the first people” to arrive at the crash scene. [KYW Radio 1060 (Philadelphia), 9/15/2001] He spends a brief time there (see Between 9:38 a.m. and 10:00 a.m. September 11, 2001), before returning to the building by about 10:00 a.m., according to his own account (see 10:00 a.m.-10:30 a.m. September 11, 2001). [9/11 Commission, 3/23/2004] Rumsfeld will later justify his actions following the attack, saying, “I was going, which seemed to me perfectly logically, towards the scene of the accident to see what could be done and what had happened.” [US Department of Defense, 8/12/2002] As journalist Andrew Cockburn will point out, though, ”[T]he country was under attack and yet the secretary of defense disappears for 20 minutes.” [C-SPAN, 2/25/2007] John Jester, the chief of the Defense Protective Service, which guards the Pentagon, will criticize Rumsfeld for heading to the crash scene at this time. He will say: “One of my officers tried to stop him and he just brushed him off. I told [Rumsfeld’s] staff that he should not have done that. He is in the national command authority; he should not have gone to the scene.” [Historical Office, Office of the Secretary of Defense, 10/19/2001] The numerous reports of Rumsfeld going outside to the crash scene are apparently contradicted by counterterrorism “tsar” Richard Clarke. In his 2004 book Against All Enemies, Clarke will give the impression that Rumsfeld never leaves a video conference for very long after the Pentagon is hit, except to move from one secure teleconferencing studio to another elsewhere in the Pentagon. [Clarke, 2004, pp. 7-9] However, video footage confirms that Rumsfeld does indeed go to the crash site. [CNN, 8/17/2002]

At some point after the White House is ordered to evacuate and while Air Force One is preparing to take off in Florida, counterterrorism “tsar” Richard Clarke activates the Continuity of Government (COG) plan. The coordinator for Continuity of Government has joined Clarke in the White House Situation Room. Clarke asks, “How do I activate COG?” Recalling this conversation, he will later comment, “In the exercises we had done, the person playing the president had always given that order.” But the coordinator replies, “You tell me to do it.” Soon after, Clarke instructs him, “Go.” [Clarke, 2004, pp. 8]

First Time COG Plan Activated - The Continuity of Government plan, which dates back to the Reagan administration, had originally prepared to set up a new leadership for the US in the event of a nuclear war. This is apparently the first time it has ever been put into effect. Clarke will recall, “Every federal agency was ordered… to activate an alternative command post, an alternative headquarters outside of Washington, DC, and to staff it as soon as possible.” Cabinet officers are dispatched around the country, and people in Congress are taken to alternative locations.

Clarke Regularly Particiated in COG Exercises - Since the 1980s, Clarke has in fact been a regular participant in secret COG exercises that rehearsed this plan. [Washington Post, 4/7/2004; ABC News, 4/25/2004] Vice President Dick Cheney and Secretary of Defense Donald Rumsfeld also participated. [Atlantic Monthly, 3/2004] Kenneth Duberstein, formerly President Reagan’s White House chief of staff, who took part in the exercises as well, will recall: “I said to myself, as we proceeded through the day [of 9/11], ‘It’s working.’ All those days of patriotic duty were coming back and they were working.” According to ABC News, “If executive branch leaders and large numbers of congressmen had been killed in an attack on the United States, the plan could have gone further, officials suggest, perhaps even with non-elected leaders of the United States taking control and declaring martial law.” [ABC News, 4/25/2004] According to a White House timeline of the events of 9/11, it is in fact Cheney that “orders implementation of Continuity of Government and Continuity of Operations procedures,” at 9:55 a.m., although, according to the Washington Post, Cheney only “officially implemented the emergency Continuity of Government orders,” rather than activating the plan. [White House, 2001; Washington Post, 1/27/2002]

After having trouble getting authorization on an Airfone to call his family (see 9:43 a.m. September 11, 2001), Flight 93 passenger Todd Beamer is able to speak to GTE customer service supervisor Lisa Jefferson. Jefferson, who quickly alerts the FBI about Beamer’s call, talks to him for 13 minutes. According to a report in the London Observer, she has the FBI simultaneously on another line, offering guidance. She immediately asks Beamer for details of the flight, like “What is your flight number? What is the situation? Where are the crew members?” With the help of a flight attendant sitting next to him, Beamer details the numbers of passengers and crew on the plane. He says the hijackers have divided the passengers into two groups, with ten of them in first class at the front of the plane, and 27 in the back. (Jefferson’s written summary of the conversation will say that the larger number of passengers was in the front. However, Beamer’s wife later says that Jefferson informed her it was in fact the other way around.) According to some reports, Beamer says three people have hijacked the plane. Two of them, armed with knives, are in the cockpit and have locked the door; the third is in first class with what appears to be a bomb strapped around his waist. A curtain has been closed separating first class from the coach section of the plane. Other accounts claim the hijacker with the bomb is in fact in the rear of the plane. According to one report in the Pittsburgh Post-Gazette, Beamer describes four hijackers in total: the two in the cockpit, the one with the bomb guarding the passengers in the back of the plane, and a fourth in first class. But the Orlando Sentinel says Beamer tells Jefferson he is free to talk because the hijacker in first class has closed the curtain, indicating there is no hijacker at the back of the plane. (Beamer himself is at the back of plane, calling from a phone in row 32.) According to an early article in Newsweek, he says that one passenger is dead and he doesn’t know about the pilots. However, journalist and author Jere Longman later writes that Beamer describes to Jefferson two people on the floor in fist class, possibly dead. The flight attendant next to him can be overheard saying these are the plane’s captain and co-pilot. The attendant does not mention their names or say they are wearing uniforms, but she sounds certain. Beamer then repeats what the attendant has told him. At some point in the call, Beamer asks, “Do you know what [the hijackers] want? Money or ransom or what?” He seems unaware of the other hijackings that have occurred. Jefferson informs him of the two planes crashing in New York. [Chicago Tribune, 9/16/2001; Pittsburgh Post-Gazette, 9/19/2001; Newsweek, 9/22/2001; Pittsburgh Post-Gazette, 9/22/2001; Pittsburgh Post-Gazette, 10/28/2001; The Guardian, 12/2/2001; Longman, 2002, pp. 198-200; Orlando Sentinel, 9/5/2002; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006, pp. 11] Beamer says of the hijackers, “It doesn’t seem like they know how to fly the plane.” [San Francisco Chronicle, 9/17/2001] He also tells Jefferson about himself, including where he is from, that he has two sons, and that his wife is expecting a third child in January. [Pittsburgh Post-Gazette, 9/22/2001] He tells her, “I just want to talk to somebody and just let someone know that this is happening.” [Longman, 2002, pp. 204]

Ben Sliney, FAA’s National Operations Manager, orders the entire nationwide air traffic system shut down. All flights at US airports are stopped. Around 3,950 flights are still in the air. Sliney makes the decision without consulting FAA head Jane Garvey, Transportation Secretary Norman Mineta, or other bosses, but they quickly approve his actions. It’s Sliney’s first day on the job. [CNN, 9/12/2001; Washington Post, 9/12/2001; MSNBC, 9/22/2001; USA Today, 8/12/2002; Associated Press, 8/12/2002; USA Today, 8/12/2002; USA Today, 8/13/2002; Associated Press, 8/21/2002] Seventy-five percent of the planes land within one hour of the order. [USA Today, 8/12/2002] The 9/11 Commission will later remark that this “was an unprecedented order” that the “air traffic control system handled… with great skill.” [9/11 Commission, 7/24/2004, pp. 29] The Washington Post has reported that Mineta told Monte Belger at the FAA: “Monte, bring all the planes down,” even adding, ”[Expletive] pilot discretion.” [Washington Post, 1/27/2002] However, it is later reported by a different Post reporter that Mineta did not even know of the order until 15 minutes later. This reporter “says FAA officials had begged him to maintain the fiction.” [Slate, 4/2/2002]

The White House is evacuated after the Secret Service receives what the Associated Press describes as a credible threat of a terrorist attack against it. [Associated Press, 2001; CNN, 9/11/2001; CNN, 9/12/2001] Minutes earlier, in the White House Situation Room, Secret Service Director Brian Stafford informed counterterrorism “tsar” Richard Clarke that an aircraft was heading in their direction, and said he was going to order the evacuation of the White House (see 9:37 a.m. September 11, 2001). [Clarke, 2004, pp. 7] The Secret Service learned of this aircraft by monitoring radar and over an open line with the FAA (the “hijack net”), which enable them to receive real time information about the hijacked aircraft. The Secret Service, which has been using an air surveillance system called Tigerwall for some time, tracks both American 77 and United 93 as they approach Washington and assumes the White House is a target. Secret Service agent Barbara Riggs will later say, “The Secret Service prepared to defend the facility,” although the precise nature of the preparations is unclear. [MSNBC, 9/22/2001; Daily Telegraph, 12/16/2001; Washington Post, 1/27/2002; Associated Press, 8/21/2002; 9/11 Commission, 6/17/2004; PCCW Newsletter, 3/2006] A slow and orderly evacuation of the White House had in fact begun earlier on (see 9:20 a.m. September 11, 2001). But now the Secret Service orders people to run so as to evacuate faster. [CNN, 9/11/2001; ABC News, 9/11/2002]

John White, a manager at the FAA’s Command Center, suggests to Doug Davis, the special assistant for technical operations in air traffic services at FAA headquarters, that fighter jets should be launched in response to Flight 93. However, FAA headquarters is apparently unable to act on this suggestion. [Federal Aviation Administration, 10/21/2002; 9/11 Commission, 7/24/2004, pp. 29; Canadian Broadcasting Corporation, 9/10/2006] In the last few minutes, the Command Center has warned headquarters that Flight 93 is “29 minutes out of Washington” and approaching the city (see 9:41 a.m.-9:48 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 44]

Command Center Asks about Launching Fighters - Davis now tells White, “They’re pulling Jeff [Griffith, the FAA’s deputy director of air traffic] away to go talk about United 93.” White asks, “Uh, do we want to think, uh, about scrambling aircraft?” Davis replies, “Oh, God, I don’t know.” White says, “Uh, that’s a decision somebody’s gonna have to make probably in the next 10 minutes.” However, Davis only responds, “Uh, ya know everybody just left the room.” [Federal Aviation Administration, 10/21/2002; 9/11 Commission, 7/24/2004, pp. 29] This conversation takes place 13 minutes after the FAA’s Cleveland Center asked the Command Center whether anyone had asked the military to launch fighter jets to intercept Flight 93 (see 9:36 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 40]

Person Who Could Request Fighters Is Unavailable - Apparently there is only one person at FAA headquarters who is authorized to request military assistance, and Ben Sliney, the Command Center’s national operations manager, is told that no one can find him. Sliney will later recount: “I said something like, ‘That’s incredible. There’s only one person. There must be someone designated or someone who will assume the responsibility of issuing an order, you know.’ We were becoming frustrated in our attempts to get some information. What was the military response?” [Canadian Broadcasting Corporation, 9/10/2006] This lack of response to Flight 93 contrasts with the FAA’s earlier reaction to Flight 11, when Boston Center air traffic controllers contacted NORAD’s Northeast Air Defense Sector (NEADS) themselves (see 8:37 a.m. September 11, 2001), and even called military bases directly (see 8:34 a.m. September 11, 2001 and 8:34 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20]

Air Force One takes off from off from Sarasota-Bradenton International Airport in Florida with President Bush on board. [USA Today, 9/11/2001; Washington Post, 1/27/2002; 9/11 Commission, 7/24/2004, pp. 39] The plane takes off without any fighter jets protecting it. “The object seemed to be simply to get the president airborne and out of the way,” an administration official will later say. [Daily Telegraph, 12/16/2001] There are still 3,520 planes in the air over the US. [USA Today, 8/13/2002] About half of the planes in the Florida region where Bush’s plane is are still airborne. [St. Petersburg Times, 9/7/2002] Apparently, fighters don’t meet up with Air Force One until over an hour and a half later (see 11:29 a.m. September 11, 2001). Counterterrorism “tsar” Richard Clarke will claim to have heard at around 9:50 a.m. from the White House bunker containing Vice President Dick Cheney that a fighter escort had been authorized. [Clarke, 2004, pp. 8-9]

One of the hijackers in the cockpit asks if anything is going on, apparently meaning outside the cockpit. “Fighting,” the other says. [Longman, 2002, pp. 210] An analysis of the cockpit flight recording suggests that the passenger struggle actually starts in the front of the plane (where Mark Bingham and Tom Burnett are sitting) about a minute before a struggle in the back of the plane (where Todd Beamer is sitting). [Observer, 12/2/2001] Officials later theorize that the Flight 93 passengers reach the cockpit using a food cart as a battering ram and a shield. They claim digital enhancement of the cockpit voice recorder reveals the sound of plates and glassware crashing around 9:57 a.m. [Newsweek, 12/3/2001]

The South Tower of the World Trade Center tilts to the southeast and then collapses. It was hit by Flight 175 at 9:03 a.m., 56 minutes earlier (see 9:03 a.m. September 11, 2001). [Washington Post, 9/12/2001; New York Times, 9/12/2001; MSNBC, 9/22/2001; USA Today, 12/20/2001; Associated Press, 8/21/2002; ABC News, 9/11/2002; National Institute of Standards and Technology, 9/2005, pp. 44] The first sign of the collapse is visible on floor 82. [National Institute of Standards and Technology, 9/2005, pp. 87] The angle of the tilt will be disputed after 9/11, as will the time it takes the towers to fall to the ground. [Scientific American, 10/9/2001; Eagar and Musso, 12/2001; PBS Nova, 5/2002; National Institute of Standards and Technology, 8/30/2006]

In the lobby of Building 7 of the WTC, EMS Division Chief John Peruggia is in discussion with Fire Department Captain Richard Rotanz and a representative from the Department of Buildings. As Peruggia later describes, “It was brought to my attention, it was believed that the structural damage that was suffered to the [Twin] Towers was quite significant and they were very confident that the building’s stability was compromised and they felt that the North Tower was in danger of a near imminent collapse.” Peruggia grabs EMT Richard Zarrillo and tells him to pass on the message “that the buildings have been compromised, we need to evacuate, they’re going to collapse.” Zarrillo heads out to the fire command post, situated in front of 3 World Financial, the American Express Building, where he relays this message to several senior firefighters. He says, “OEM says the buildings are going to collapse; we need to get out.” (OEM is the Mayor’s Office of Emergency Management, which has its headquarters in WTC 7.) Fire Chief Pete Ganci’s response is, “who the f___ told you that?” Seconds later, they hear the noise of the South Tower as it collapses. [City of New York, 10/23/2001; City of New York, 10/25/2001; City of New York, 10/25/2001; City of New York, 11/9/2001] Others also appear to have been aware of the imminent danger. Fire Chief Joseph Pfeifer, who is at the command post in the lobby of the North Tower, says, “Right before the South Tower collapsed, I noticed a lot of people just left the lobby, and I heard we had a crew of all different people, high-level people in government, everybody was gone, almost like they had information that we didn’t have.” He says some of them are moving to a new command post across the street. [City of New York, 10/23/2001; Firehouse Magazine, 4/2002; Dwyer and Flynn, 2005, pp. 214] Mayor Giuliani also says he receives a prior warning of the first collapse, while at his temporary headquarters at 75 Barclay Street (see (Before 9:59 a.m.) September 11, 2001).

The military liaison at the FAA’s Cleveland Center calls NORAD’s Northeast Air Defense Sector (NEADS) and alerts it to the hijacked Flight 93. According to the 9/11 Commission, this is the first notification NEADS receives about Flight 93, but it comes too late, since the plane has already crashed (see 10:06 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 30; 9/11 Commission, 8/26/2004, pp. 46]

‘Bomb on Board’ Flight 93 - At 10:05 a.m., the military liaison at the Cleveland Center, who is unaware that Flight 93 has just crashed, calls NEADS to inform it that Flight 93 is heading toward Washington, DC. Even though communicating with NEADS is not one of his responsibilities, he wants to make sure it is in the loop. [Spencer, 2008, pp. 224] At NEADS, the call is answered by Tech Sergeant Shelley Watson. Shortly into the call, at 10:07, the military liaison tells her: “We got a United 93 out here. Are you aware of that?” He continues, “That has a bomb on board.” Watson asks: “A bomb on board? And this is confirmed? You have a mode three [beacon code], sir?” The military liaison replies, “No, we lost his transponder” (see 9:40 a.m. September 11, 2001). The news about Flight 93 is shouted out to Major Kevin Nasypany, the NEADS mission crew commander. Nasypany responds: “Gimme the call sign. Gimme the whole nine yards.… Let’s get some info, real quick. They got a bomb?”

Liaison Wants Fighters Sent toward Flight 93 - The military liaison continues, asking Watson if NEADS scrambled fighter jets in response to Delta 1989, an aircraft that was mistakenly reported as having been hijacked (see 9:28 a.m.-9:33 a.m. September 11, 2001 and 9:39 a.m. September 11, 2001). Watson replies: “We did. Out of Selfridge and Toledo” (see 9:55 a.m. September 11, 2001 and 10:01 a.m. September 11, 2001), and says these jets are airborne. When the military liaison asks if the fighters can be directed to where Flight 93 is, Watson asks him if the Cleveland Center has latitude and longitude coordinates for this aircraft. The military liaison replies that he has not got this information available right now. All he knows is that Flight 93 has “got a confirmed bomb on board… and right now, his last known position was in the Westmoreland area.… Which is… in the Pittsburgh, Pennsylvania, area.” [North American Aerospace Defense Command, 9/11/2001; Vanity Fair, 8/1/2006]

NEADS Searches on Radar - The news of a bomb on board Flight 93 spreads quickly at NEADS, and personnel there search for the aircraft’s primary return on their radar screens. But because the plane has already crashed, they will be unable to locate it. NEADS will only learn that Flight 93 has crashed at 10:15 a.m., during a call with the FAA’s Washington Center (see 10:15 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 30-31]

FAA Failed to Notify Military Earlier - The Cleveland Center’s notification to NEADS about Flight 93 comes 39 minutes after the plane was hijacked (see 9:28 a.m. September 11, 2001) and 33 minutes after FAA headquarters was alerted to the hijacking (see 9:34 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 11, 28] At the time NEADS is alerted to Flight 93, NORAD is similarly uninformed about this aircraft, according to the 9/11 Commission. The Commission will state, “At 10:07, its representative on the air threat conference call stated that NORAD had ‘no indication of a hijack heading to DC at this time.‘” According to the Commission, the National Military Command Center (NMCC) at the Pentagon learned about the Flight 93 hijacking slightly earlier on, at 10:03 a.m. (see 10:03 a.m. September 11, 2001). However, the NMCC was notified by the White House, not the FAA. [9/11 Commission, 7/24/2004, pp. 42] A former senior FAA executive, speaking on condition of anonymity, will later try to explain why it takes the FAA so long to alert NEADS to Flight 93. He will say, “Our whole procedures prior to 9/11 were that you turned everything [regarding a hijacking] over to the FBI.” [Vanity Fair, 8/1/2006] Yet military instructions contradict this, stating, “In the event of a hijacking, the NMCC will be notified by the most expeditious means by the FAA.” [US Department of Defense, 7/31/1997; US Department of Defense, 6/1/2001]

NORAD Commanders Claim Earlier Awareness of Flight 93 - Two senior NORAD officials will contradict the 9/11 Commission’s conclusion, and claim they were aware of Flight 93 well before it crashed (see Shortly Before 9:36 a.m. September 11, 2001 and 9:36 a.m.-10:06 a.m. September 11, 2001). [Filson, 2003, pp. 68, 71-73] Colonel Robert Marr, the NEADS battle commander, will tell the Commission that, while the flight was still airborne, “his focus was on UAL 93, which was circling over Chicago,” and he “distinctly remembers watching the flight UAL 93 come west, and turn over Cleveland.” [9/11 Commission, 10/27/2003; 9/11 Commission, 1/23/2004] Major General Larry Arnold, the commander of the Continental US NORAD Region, will recall, ”[W]e watched the [Flight] 93 track as it meandered around the Ohio-Pennsylvania area and started to turn south toward DC.” [Filson, 2003, pp. 71]

Flight 93 crashes into an empty field just north of the Somerset County Airport, about 80 miles southeast of Pittsburgh, 124 miles or 15 minutes from Washington, D.C. Presumably, hijackers Ziad Jarrah, Ahmed Alhaznawi, Ahmed Alnami, Saeed Alghamdi, and all the plane’s passengers are killed instantly. [CNN, 9/12/2001; North American Aerospace Defense Command, 9/18/2001; Guardian, 10/17/2001; USA Today, 8/12/2002; Associated Press, 8/21/2002; MSNBC, 9/3/2002] The point of impact is a reclaimed coal mine, known locally as the Diamond T Mine, that was reportedly abandoned in 1996. [Pittsburgh Tribune-Review, 9/12/2001; St. Petersburg Times, 9/12/2001; Pittsburgh Tribune-Review, 9/11/2002] Being “reclaimed” means the earth had been excavated down to the coal seam, the coal removed, and then the earth replaced and planted over. [Kashurba, 2002, pp. 121] A US Army authorized seismic study times the crash at five seconds after 10:06 a.m. [Kim and Baum, 2002; San Francisco Chronicle, 12/9/2002] As mentioned previously, the timing of this crash is disputed and it may well occur at 10:03 a.m., 10:07 a.m., or 10:10 a.m.

In a phone call with Vice President Dick Cheney, President Bush authorizes the military to shoot down hostile aircraft. Minutes earlier, in the Presidential Emergency Operations Center (PEOC) below the White House, a military aide had asked Cheney for the authority to engage what appeared to be an inbound aircraft, and Cheney had promptly given it (see (Between 10:10 a.m. and 10:15 a.m.) September 11, 2001). During a subsequent quiet moment, deputy White House chief of staff Josh Bolten, who is also in the PEOC, suggested to Cheney that he contact the president to confirm the engage order. Therefore at 10:18 a.m., according to White House logs, Cheney calls Bush, who is on board Air Force One, and speaks with him for two minutes. White House press secretary Ari Fleischer notes that at 10:20 a.m., Bush informs him that he has authorized the shootdown of aircraft, if necessary. According to the 9/11 Commission, “Fleischer’s 10:20 note is the first mention of shootdown authority.” [9/11 Commission, 7/24/2004, pp. 41 and 465] Bush’s senior adviser Karl Rove, who is also on Air Force One, gives a similar account, later telling NBC News that “at about 10:20,” Bush goes from his office into the private cabin in front of it, “and took a phone call, and came back in and said that he had talked to the vice president and to the secretary of defense and gave the authorization that [the] military could shoot down any planes not under control of their crews that were gearing critical targets.” [MSNBC, 9/11/2002] But other accounts indicate the president gives the shootdown authorization earlier than this. Bush and Cheney will claim that Bush gives the authorization during a call estimated to occur between about 10:00 and 10:15 (see (Between 10:00 a.m. and 10:15 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 40] Similarly, according to journalists Bob Woodward and Bill Sammon, Bush gives it in a call with Cheney soon after 9:56, when Air Force One takes off (see (Shortly After 9:56 a.m.) September 11, 2001). [Sammon, 2002, pp. 102; Woodward, 2002, pp. 17-18; Washington Post, 1/27/2002] Counterterrorism “tsar” Richard Clarke says it is given even earlier. He states that, at some point between about 9:38 and 9:56, he is instructed to tell the Pentagon it has authorization from the president to shoot down hostile aircraft (see 9:38 a.m. September 11, 2001 and (Between 9:45 a.m. and 9:56 a.m.) September 11, 2001). [ABC News, 11/29/2003; Clarke, 2004, pp. 8]

The North Tower of the World Trade Center tilts to the south and then collapses. Its north side was hit by Flight 11 at 8:46, 102 minutes earlier. [CNN, 9/12/2001; MSNBC, 9/22/2001; Kim and Baum, 2002; Associated Press, 8/21/2002; National Institute of Standards and Technology, 9/2005, pp. 33] After the antenna starts to move (see 10:28 a.m. September 11, 2001), the next sign that the top section of the building is moving downward is on floor 98, at the top of the impact zone. [National Institute of Standards and Technology, 9/2005, pp. 22, 87] The angle of the tilt will be disputed after 9/11, as will the time it takes the towers to fall to the ground. [Scientific American, 10/9/2001; Eagar and Musso, 12/2001; PBS Nova, 5/2002; National Institute of Standards and Technology, 8/30/2006] The death toll could have been much worse—an estimated 15,000 people made it out of the WTC to safety after 8:46 a.m. [St. Petersburg Times, 9/8/2002]

An anonymous phone call is received at the White House in which the caller says Air Force One, the president’s plane, will be the next terrorist target and uses code words indicating they have inside information about government procedures. [Cheney, 9/11/2001; New York Times, 9/13/2001; Woodward, 2002, pp. 18] Air Force One is currently flying toward Barksdale Air Force Base in Louisiana, with President Bush on board (see 10:20 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 325] The White House receives a call from an anonymous individual, warning that the next target of the terrorist attacks will be Air Force One. The caller refers to the plane as “Angel.” [Sammon, 2002, pp. 106-107; Woodward, 2002, pp. 18; 9/11 Commission, 7/24/2004, pp. 554; Darling, 2010, pp. 60-61] “Angel” is the Secret Service’s code name for Air Force One. [Williams, 2004, pp. 81; CBS News, 11/25/2009] An unnamed “high White House official” will later say the use of “American code words” shows the caller has “knowledge of procedures that made the threat credible.” [New York Times, 9/13/2001]

Government Officials Told about Threat - News of the threatening call is promptly passed on to government officials in the Presidential Emergency Operations Center (PEOC)—a bunker below the White House—and reported on the Pentagon’s air threat conference call. [US Department of Defense, 9/11/2001; Newsweek, 12/30/2001; 9/11 Commission, 7/24/2004, pp. 554; Darling, 2010, pp. 60-61] Vice President Dick Cheney, who is in the PEOC, will comment that the news “reinforced the notion here… that the government has been targeted and that we need to be extra careful about making certain we protected the continuity of government, secured the president, secured the presidency.” [White House, 11/19/2001] According to Major Robert Darling of the White House Military Office, who is also in the PEOC, “The talk among the principals in the room quickly determined that the use of a code word implied that the threat to Air Force One and the president could well be from someone with access to [the president’s] inner circle—possibly someone who was near the president at that very moment.” [Darling, 2010, pp. 61]

Accounts Conflict over Who Receives Call - It is unclear who at the White House answers the call in which the threat against Air Force One is made. The call is received by the White House switchboard, according to some accounts. [Sammon, 2002, pp. 106; Fleischer, 2005, pp. 141-142] Other accounts will indicate it is received by the White House Situation Room. [9/11 Commission, 7/24/2004, pp. 554; Darling, 2010, pp. 60-61] Eric Edelman, a member of Cheney’s staff who is in the PEOC, will say the call is received by the Secret Service. [White House, 10/25/2001] But two Secret Service agents who are on duty today will deny “that their agency played any role in receiving or passing on a threat to the presidential jet,” according to the Wall Street Journal. [Wall Street Journal, 3/22/2004] However, a Secret Service pager message will be sent at 10:32 a.m., which states that the “JOC”—the Secret Service Joint Operations Center at the White House—has received an “anonymous call” reporting that “Angel is [a] target.” [CBS News, 11/25/2009]

Military Officer Passes on Details of Threat - Officials in the PEOC reportedly learn about the threat to Air Force One from a military officer working in the center. Although Cheney will say the threat “came through the Secret Service,” he will say later this year that he is unsure who passed the details of it to those in the PEOC. [Meet the Press, 9/16/2001; White House, 11/19/2001] An official in Cheney’s office will say in 2004 that Cheney was informed of the threat by “a uniformed military person” manning the PEOC, although Cheney and his staff are unaware who that individual was. [Wall Street Journal, 3/22/2004] National Security Adviser Condoleezza Rice will say that those in the PEOC are told about the threat by a “communicator,” meaning one of the military officers who works in the PEOC, and is responsible for “establishing phone lines and video lines, and staying in touch with the National Military Command Center” at the Pentagon. [White House, 11/1/2001] The military officer Rice is referring to may be Darling. Darling will recall that he answers a call from the White House Situation Room about the threat to Air Force One and then passes on the information he receives to Rice, telling her, “Ma’am, the [Situation Room] reports that they have a credible source in the Sarasota, Florida, area that claims Angel is the next target.” Rice immediately passes on the news to Cheney, according to Darling. [Darling, 2010, pp. 60-61] Cheney will subsequently call Bush and tell him about the threat (see 10:32 a.m. September 11, 2001). [Sammon, 2002, pp. 106-107; CBS News, 9/11/2002]

Reason for ‘Bogus’ Threat Unclear - The threat will be determined to be “almost surely bogus,” according to Newsweek. [Newsweek, 12/30/2001] The Secret Service’s intelligence division tracked down the origin of this threat,” the 9/11 Commission Report will state, “and, during the day, determined that it had originated in a misunderstanding by a watch officer in the White House Situation Room.” Although the 9/11 Commission will say it found the intelligence division’s “witnesses on this point to be credible,” Deborah Loewer, the director of the White House Situation Room, will dispute this account. [9/11 Commission, 7/24/2004, pp. 554] By the end of 2001, White House officials will say they still do not know where the threat came from. [Newsweek, 12/30/2001] Darling will write in 2010, “To this day, it has never been determined why either the ‘credible source’ or Situation Room personnel used that code word [i.e. ‘Angel’] in their report to the PEOC.” [Darling, 2010, pp. 62] “The best we can tell,” Rice will say, is that “there was a call that talked about events—something happening to the president on the ground in Florida. And that somehow got interpreted as Air Force One.” She will say that the fact the caller knew the code name for Air Force One is “why we still continue to suspect it wasn’t a crank call.” [White House, 11/1/2001] However, former Secret Service officials will say the code name wasn’t an official secret, but instead “a radio shorthand designation that had been made public well before 2001.” [Wall Street Journal, 3/22/2004]

US airspace is clear of all civilian air traffic, with the exception of a small number of law enforcement and emergency operations aircraft. Otherwise, only military aircraft are airborne. [Federal Aviation Administration, 9/18/2001; Federal Aviation Administration, 4/15/2002; USA Today, 8/12/2002] The FAA’s Command Center in Herndon, Virginia, announces that the airspace has been successfully shut down. [Spencer, 2008, pp. 269] At 9:26 a.m., the Command Center ordered a national ground stop that prevented any aircraft from taking off (see 9:26 a.m. September 11, 2001), and at 9:45 a.m. it ordered FAA facilities to instruct all aircraft to land at the nearest airport (see 9:45 a.m. September 11, 2001). Since then, about 4,500 commercial and general aviation aircraft have landed without incident. This is the first time ever that all civilian aircraft in the United States have been grounded. [US Congress. House. Committee On Transportation And Infrastructure, 9/21/2001; Federal Aviation Administration, 3/21/2002; 9/11 Commission, 7/24/2004, pp. 29] Author Pamela Freni will later comment that this clearing of the skies was “a tremendous feat accomplished by a huge team that had never even practiced this part of the game before.” Frank Hatfield, the air traffic division manager for the FAA’s eastern region, will comment: “What we did on September 11 was done amazingly well. It was almost like World War II, the way the airplanes were handled.” [Freni, 2003, pp. 69] At 12:30 p.m., the FAA will report that there are 50 flights in US airspace, but none of them are reporting any problems.

Before going to sleep, President Bush writes in his diary, “The Pearl Harbor of the 21st century took place today.… We think it’s Osama bin Laden.” [Washington Post, 1/27/2002]
