The head of the agency that provides security at the Pentagon informs another military employee that the Pentagon is unprotected against an aerial attack. In reaction to the news of the attacks on New York, Army Deputy Administrative Assistant Sandra Riley telephones John Jester, the chief of the Defense Protective Service (DPS)—the law enforcement agency that guards the Pentagon. She asks him, “What do we have in place to protect from an airplane?” He tells her, “Nothing.” According to the Defense Department’s book about the Pentagon attack: “The Pentagon did not have an antiaircraft system on the roof of the building or on the grounds. Even if DPS had received word of an inbound plane, it had no plan to counter a suicide air attack. Had a warning been issued in time, DPS’s only effective response would have been evacuation and dispersal of the building’s occupants.” [Goldberg et al., 2007, pp. 152] The Washington Post will similarly claim the Pentagon has “no anti-aircraft guns posted on its roof, nor any radars of its own for tracking local air traffic.” [Washington Post, 9/16/2001] Yet, at the nearby White House, the Secret Service is believed to have a battery of ground-to-air Stinger missiles ready to defend the place.

Between 9:03 a.m. and 9:37 a.m. September 11, 2001: American Airlines and FAA Command Center Again Discuss Loss of Flight 77
American Airlines and the FAA Command Center discuss the hijacking of Flight 77 again, apparently at some point between when Flight 175 hits the World Trade Center at 9:03 (see 9:03 a.m. September 11, 2001) and Flight 77 hits the Pentagon at 9:37 (see 9:37 a.m. September 11, 2001). Although American Airlines was initially informed of the hijacking by the FAA (see 8:58 a.m. September 11, 2001 and 9:02 a.m. September 11, 2001), at this point an American Airlines employee calls an FAA employee and tells him that Flight 77 has been hijacked. The FAA employee appears to be unaware of this hijacking, as, when he is told that American Airlines is missing a second plane (in addition to Flight 11, which has hit the World Trade Center) he asks for the flight number and inquires when the company last knew something about the flight. The American Airlines employee responds by saying, “we were talking to them according to Indianapolis Center about 45 minutes ago.” As the last recorded communication with Flight 77 was as at 8:51 (see 8:51 a.m. September 11, 2001), this would put this conversation at around 9:36. However, this conversation is part of a transcript of discussions by FAA employees and others, and in the transcript it appears shortly after the first mention of Flight 175’s crash at 9:03, indicating it may have occurred earlier than 9:36.

Between 9:03 a.m. and 9:37 a.m. September 11, 2001: Defense Official at Pentagon Says, ‘We’re Next’
After the second WTC tower is hit, NBC News correspondent Jim Miklaszewski is heading down a hall inside the Pentagon when he runs into a Defense Department official. The official says he doesn’t yet know anything specific about the attack. But, he says, it is so coordinated that “[i]f I were you I would stay off the E-ring [the outermost corridor of the Pentagon] today, because we’re next.” According to Miklaszewski, the official had no specific information, “that was just his gut instinct.” [Gilbert et al., 2002, pp. 43]
9:04 a.m.-9:36 a.m. September 11, 2001: People in Buildings near Pentagon Concerned They Might be Targets of Attack
People in the vicinity of the Pentagon, including the managers of the high USA Today building, phone the local emergency call center, with concerns about their own safety. [Creed and Newman, 2008, pp. 48; McClatchy Washington Bureau, 2008] The Emergency Communications Center (ECC) is the focal point of all police and fire 911 calls for Arlington County, where the Pentagon is located. [Goldberg et al., 2007, pp. 66] After events in New York make it clear the US is under attack, the phones there light up with calls from local people wanting to know what to do. [Creed and Newman, 2008, pp. 48] According to Assistant Chief James Schwartz of the Arlington County Fire Department, the center is “receiving phone calls from buildings that are along the [Potomac] river and are also along the flight path for [Washington’s Reagan] National Airport,” which is about a mile from the Pentagon. [McClatchy Washington Bureau, 2008]
USA Today Building Managers Concerned – Among the callers to the ECC are the building managers at the USA Today building in Rosslyn, who are worried their complex could be a target and want to know if they should evacuate it. [Creed and Newman, 2008, pp. 48] The USA Today complex is just a few miles down the road from the Pentagon. [USA Today, 9/13/2001] It includes the two tallest high-rise buildings in the county, one of which is 30-stories high. [Washington Business Journal, 9/11/2001; Creed and Newman, 2008, pp. 9] These two buildings are in fact known as the “Twin Towers.” [Washington Business Journal, 9/7/2001]
ECC Suggests Evacuation – The ECC has no specific guidance it can offer the building managers, but tells them that if it makes them feel better, based on what they are seeing on television, then they should evacuate their building. [McClatchy Washington Bureau, 2008] Some employees will begin evacuating from the USA Today building after the Pentagon is hit at 9:37. However, Westfield Realty, the company that owns the building, will not ask the tenants to evacuate until around 11:00 a.m. [Washington Business Journal, 9/11/2001; Washington Business Journal, 9/14/2001]
Firefighters Think USA Today Building Is a Possible Target – Around the time that the ECC is receiving calls from concerned people in the area, firefighters at a local fire station who have seen the television footage of the attacks in New York start speculating what landmarks terrorists might go for if they attacked northern Virginia. The firefighters in fact see the USA Today complex as the most obvious target, but they also consider the Pentagon, CIA headquarters, the White House, and the Capitol building to be potential targets. [Creed and Newman, 2008, pp. 9-10] Just before the time of the Pentagon attack, a fire alarm will go off at the USA Today building, though it is unclear whether this is actually caused by a fire there (see (Shortly Before 9:37 a.m.) September 11, 2001). [McClatchy Washington Bureau, 2008]
Shortly After 9:03 a.m. September 11, 2001: FAA Manager Linda Schuessler Responds to Second WTC Crash, Secures FAA Command Center
After staff members at the FAA’s Command Center in Herndon, Virginia, see the second attack on the World Trade Center live on CNN, Linda Schuessler, the deputy director of system operations there, makes the decision to secure the center in order to protect the building and its occupants. The Command Center’s doors are locked and all non-FAA personnel are ordered to leave the premises immediately. [Freni, 2003, pp. 64; Spencer, 2008, pp. 80-81] Schuessler will later say her reason for doing this is “because we didn’t know exactly what the situation was and what was going on.” [Aviation Week and Space Technology, 12/17/2001] At some point early on, she also assigns a member of staff to each manager at the Command Center, to be a note-taker and keep a record of every decision and order given by that manager. She realizes that documentation of all actions will be crucial for later recreating the day’s events. [Freni, 2003, pp. 65]
FAA Managers Gather Information – Schuessler will recall that, following the second attack, those in the Command Center start receiving information from FAA field facilities, “about unusual things that were going on.” National operations manager Ben Sliney, three first-level supervisors, and Schuessler are involved in gathering together information from around the country that the specialists at the Command Center are receiving. Schuessler will recall, “Every few minutes, we would gather in the middle of the operational floor and share the information and discuss what some of our options might be, what we needed to be doing.” [Aviation Week and Space Technology, 12/17/2001; Freni, 2003, pp. 64]
Schuessler Standing in for Absent Manager – Linda Schuessler has come to the Command Center after working at FAA headquarters, and lacks operation-level experience there. [Spencer, 2008, pp. 81] She is in charge of the Command Center this morning only because Jack Kies, the FAA’s manager of tactical operations, who would normally be in charge, is away for a meeting in Nashua, New Hampshire (see 8:30 a.m. September 11, 2001). [Freni, 2003, pp. 65-66; Federal Aviation Administration, 5/18/2006] According to author Lynn Spencer, Schuessler therefore focuses on staying out of Ben Sliney’s way, and taking care of administrative tasks. [Spencer, 2008, pp. 81]
9:04 a.m. September 11, 2001: Military Raises ‘Infocon’ Threat Level
The 1st Fighter Wing at Langley Air Force Base, Virginia, receives notification from NORAD of an increased Information Operations Condition (Infocon) threat level. The message from NORAD directs the 1st Fighter Wing command post to upgrade the Infocon computer security level from Normal to Alpha. According to the wing’s own records, this is “the first message correspondence” the wing receives “to indicate that September 11th would not be an average day.” [1st Fighter Wing History Office, 12/2001] Steps to be taken under Infocon Alpha reportedly include “changing passwords, updating keys used to create classified communication lines, minimizing cell phone use, backing up important documents on hard drive, updating virus protection on home computers, reporting suspicious activity, and reviewing checklists.” [Colorado Springs Gazette, 5/3/2001]
Five Security Levels – The Infocon system provides a structured, coordinated approach for defending against and reacting to attacks on Defense Department systems and networks. It comprises five levels of threat, each with its own protective procedures. These levels go from Normal, through Alpha, Bravo, and Charlie, up to Delta. [IAnewsletter, 12/2000 ; General Accounting Office, 3/29/2001 ] General Ralph Eberhart, the commander of both the US Space Command and NORAD, is responsible for evaluating the threat to military computers and issuing information conditions—“Infocons”—to the US military. [Colorado Springs Gazette, 5/3/2001] He is presumably therefore responsible for currently raising the Infocon level.
Threat Level Lowered on Previous Evening – The Infocon level was in fact lowered to Normal the previous evening, reportedly because of a reduced threat to US computer networks from hacker and virus attacks (see September 10, 2001). [1st Fighter Wing History Office, 12/2001] The 1st Fighter Wing is the “host unit” at Langley Air Force Base, which is about 130 miles from Washington, DC. It includes three fighter squadrons, which fly the F-15 Eagle fighter jet. [Virginian-Pilot, 9/20/2001; Langley Air Force Base, 11/2003; Air Force Print News, 11/9/2006]
Shortly After 9:03 a.m. September 11, 2001: Capitol Building Not Evacuated, despite Being a Possible Target
Despite being a potential target for terrorists, the US Capitol building in Washington is not evacuated when the second World Trade Center tower is hit and it is clear the US is under attack. [CNN, 9/11/2002] Senate Majority Leader Tom Daschle (D-SD) is in the lobby of his office at the Capitol, and some of his staff members there are watching the television coverage of events in New York. Daschle has already been told about the first plane hitting the WTC, and then sees the second one hitting the South Tower live on television. As Daschle later recalls, he now realizes, “This is an attack.” Former Senator John Glenn (D-OH), who has stopped by to say hello to Daschle, now warns him: “I’m not sure you ought to be here. This would be a logical target.” Indeed, Daschle will later comment, “I’ve heard people observe since that day what a prime target the Capitol building makes for such an air attack—this brilliant white structure perched on its own terraced hill, its dome outlined against the sky, with the broad, sprawling expanse of the Mall leading up to it like a long open runway.” [Daschle and D’Orso, 2003, pp. 105-107; Kent State University, 5/10/2004] A bestselling 1994 novel by Tom Clancy in fact included the plotline of a suicide pilot deliberately crashing a Boeing 747 into the Capitol building (see August 17, 1994). [New York Times, 10/2/1994; Newsday, 5/20/2002] Yet Daschle is able to continue with his scheduled weekly team meeting with his senior staff, where they discuss budget issues. [Daschle and D’Orso, 2003, pp. 106-107] Even by the time the Pentagon is hit, more than 25 minutes later, there will still have been no evacuation of the Capitol. [CNN, 9/11/2002] The building will eventually be evacuated around 9:48 a.m., reportedly due to fears of a plane approaching it (see 9:48 a.m. September 11, 2001). [Associated Press, 8/21/2002; Daschle and D’Orso, 2003, pp. 109; Hastert, 2004, pp. 8]
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]
After 9:03 a.m. September 11, 2001: Cyberattacks Cause Some Government Websites to Go Down
Numerous government websites, which are a source of critical information, go offline, allegedly due in part to malicious attacks by computer hackers. [Akamai, 9/11/2015; Business Times, 9/24/2016] Many people seeking details about the terrorist attacks are turning to the Internet to find out what is happening, since it can quickly provide them with the information they want. However, numerous key websites, including government websites and news websites, go offline. [Washington Post, 9/11/2013; Akamai, 9/9/2014; Jewish Review of Books, 12/2014] The websites of the New York Times, CNN, and NBC News, for example, are unavailable between 9:00 a.m. and 10:00 a.m. [Network World, 9/17/2001] Other websites that could provide valuable information that are affected include the websites of the FBI, the Red Cross, and American Airlines. [Raskin, 2013, pp. 209-210; Jewish Review of Books, 12/2014]
‘Bad Actors’ Launch Attacks on Key Websites – There are two reasons for the websites going down, according to Tom Leighton, chief scientist at the high-tech firm Akamai. One is simply that the increase in traffic caused by large numbers of people turning to the Internet for information is overloading them. [Akamai, 9/9/2014; Business Times, 9/24/2016] The website of the Washington Post, for example, is receiving 10 times its usual number of page views. [Network World, 9/17/2001] The other reason is that “bad actors” are coming out and committing cyberattacks. [Forbes, 3/25/2019] “The crazies came out and… attacked key websites to make it… even more likely that they would go down,” Leighton will later recall. Due to these cyberattacks, he will say, “a lot of government websites went down.” [Akamai, 9/9/2014]
FBI Website Goes Down – Among others, the website of the FBI goes offline. This is due to an increase in traffic, which may have been caused by deliberate attacks. The FBI “suspected at least some of [the extra traffic] was malicious—opportunistic hackers launching denial of service attacks and causing other mischief,” the Washington Post will report. [Washington Post, 9/11/2013] (A “distributed denial of service” attack involves thousands of compromised computers being used to target a website or server at the same time, thereby causing it to overload and become unavailable. [Business Times, 9/24/2016] )
Attacks Make It Harder to Get Information Out – Whether the identities of those launching the suspected cyberattacks will subsequently be determined, and whether the cyberattacks are connected to the terrorist attacks at the World Trade Center and the Pentagon, is unstated. Leighton will only comment that he is unaware whether the cyberattacks were coordinated. [Akamai, 9/9/2014] All the same, a consequence of them is that “it became even harder to get the news [about the terrorist attacks] out,” Leighton will note. [Forbes, 3/25/2019] In addition to the problem of important websites going offline, people in New York and Washington, DC, experience communication problems today due to difficulties making phone calls, particularly cell phone calls (see (After 8:55 a.m.) September 11, 2001) and (After 10:00 a.m.) September 11, 2001). [New York Times, 9/20/2001; SatNews, 10/19/2001; Verton, 2003, pp. 148-149]
Shortly After 9:03 a.m. September 11, 2001: White House Officials Reportedly Converge on Vice President Cheney’s Office, but Accounts Conflict
Vice President Dick Cheney sees the second plane hitting the World Trade Center live on television while meeting with his speechwriter John McConnell. He later claims that several other officials then come and join him in his White House office: National Security Adviser Condoleezza Rice, political adviser Mary Matalin, and his chief of staff, I. Lewis “Scooter” Libby, who has come across from the Old Executive Office Building next door to the White House. [Meet the Press, 9/16/2001] According to journalist and author Stephen Hayes, “As word of the attacks spread throughout the West Wing, many White House officials migrated to Cheney’s office.” As well as Rice, Libby, and Matalin, these include Sean O’Keefe, the deputy director of the Office of Management and Budget; Josh Bolten, the deputy White House chief of staff; and counterterrorism “tsar” Richard Clarke. [Hayes, 2007, pp. 332] However, other accounts contradict this. Clarke claims that when he arrives at the White House shortly after 9:03, he sees the vice president and Rice, but the two are “alone in Cheney’s office” (see (9:05 a.m.) September 11, 2001). (It is possible, though, that the other officials only arrive after Clarke ends his brief visit to the vice president’s office.) [Clarke, 2004, pp. 1-2] In numerous interviews where she discusses her actions this morning, Rice makes no mention of heading to Cheney’s office after the second tower is hit. [O, the Oprah Magazine, 2/1/2002; BBC Radio 4, 8/1/2002 ; Australian Broadcasting Corporation, 9/11/2002; MSNBC, 9/11/2002; New York Times, 9/11/2002] Also, according to some accounts, the Secret Service evacuates Cheney from his office shortly after the second attack occurs (see (Shortly After 9:03 a.m.) September 11, 2001). [New York Times, 9/13/2001; ABC News, 9/14/2002] Cheney claims that President Bush phones him around this time, while he is still in his office. [Meet the Press, 9/16/2001] But according to White House adviser Karl Rove, who is with the president in Florida, Bush is unable to reach the vice president because Cheney is being evacuated from his office (see (9:16 a.m.-9:29 a.m.) September 11, 2001). [MSNBC, 9/11/2002]
