The two F-15 fighter jets launched from Otis Air National Guard Base in response to Flight 11 (see 8:46 a.m. September 11, 2001) are finally able to refuel, after they request to rendezvous with a tanker plane that was scheduled to refuel Otis fighters out on training missions this morning. [Aviation Week and Space Technology, 6/3/2002; Spencer, 2008, pp. 153]
Fighters Low on Fuel – By around 9:35 a.m., according to author Lynn Spencer, the two Otis fighters are running increasingly low on fuel and need to find a fuel tanker right away. For about the last 25 minutes, technicians at NORAD’s Northeast Air Defense Sector (NEADS) have been searching for a tanker (see (9:09 a.m.) September 11, 2001). [Spencer, 2008, pp. 112 and 152-153] A member of staff at NEADS in fact talked over the radio with a KC-135 tanker from Bangor, Maine, at around 9:05 a.m., and the plane’s crew agreed to provide support to the Otis fighters launched in response to Flight 11 (see 9:04 a.m.-9:06 a.m. September 11, 2001). [North American Aerospace Defense Command, 9/11/2001; North American Aerospace Defense Command, 9/11/2001] However, the pilots of these fighters have apparently not heard back from NEADS about whether it has been able to find a tanker for them. Now one of the pilots, Major Daniel Nash, has come up with a solution. Prior to being put on alert duty, he had been acting as the scheduling officer at Otis Air Base, and he therefore knows that a training mission a number of Otis fighters were scheduled to fly today called for refueling (see (9:00 a.m.-9:24 a.m.) September 11, 2001). Consequently he knows about the KC-135 tanker plane from Bangor that NEADS communicated with earlier on, which had been scheduled to support those fighters during their training. [102nd Fighter Wing, 2001; Spencer, 2008, pp. 152-153]
Tanker Heading toward Training Airspace – The tanker plane, which has the call sign “Maine 85,” is one of the eight KC-135s that are attached to the 101st Air Refueling Wing, based at Bangor International Airport. Its pilots are Lieutenant Colonel Adam Jenkins and Lieutenant Colonel Andy Marshall. [Portland Press Herald, 9/13/2001; Bangor Daily News, 9/9/2011] It had been scheduled to rendezvous with the Otis fighters on their training mission about 20 minutes from now in “Whiskey 105,” the military training airspace just south of Long Island, where Nash and his fellow Otis pilot Timothy Duffy had earlier been flying in a “holding pattern” (see 9:09 a.m.-9:13 a.m. September 11, 2001). The KC-135 should be on its way there now. Nash calls Duffy and tells him, “[W]e have a tanker scheduled for the training missions this morning off the coast in 105.” Duffy calls NEADS and requests that the KC-135 orbit at 20,000 feet above New York’s JFK International Airport. NEADS then coordinates with the 101st Air Refueling Wing to borrow the tanker. [Aviation Week and Space Technology, 6/3/2002; Spencer, 2008, pp. 153]
Tanker Directed toward New York – The KC-135 is instructed to fly toward Manhattan. Jenkins will later recall, “We were told to start heading west to the city.” The voice over his radio tells him, “We’ll give you details along the way.” [Bangor Daily News, 9/9/2011] Soon, the KC-135 is flying an orbit over JFK Airport and the two Otis fighters then take turns refueling. [Grant, 2004, pp. 21; Grant and Thompson, 10/6/2006, pp. 4 
; Spencer, 2008, pp. 153] According to the 9/11 Commission Report, the two Otis fighters arrived over Manhattan at 9:25 a.m. (see 9:25 a.m. September 11, 2001), but accounts of most witnesses on the ground indicate they do not arrive there until after 10:00 a.m. (see (9:45 a.m.-10:45 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 24]
Shortly Before 9:37 a.m. September 11, 2001: Chief of Pentagon Defense Protective Service Instructs Deputy to Raise Alert Level
John Jester, the chief of the Defense Protective Service (DPS), which guards the Pentagon, finally gives the instruction to raise the Pentagon’s state of alert, though only by one level. Jester had been in his office on the fourth floor of the Pentagon when he learned of the attacks in New York (see Shortly After 9:03 a.m. September 11, 2001). He had reviewed contingency plans and procedures for increasing security with DPS Major James Phillips, and then headed to the office of David O. “Doc” Cooke, the head of the Washington Headquarters Services. Jester next goes to the office of his immediate supervisor Paul Haselbush, the director of real estate and facilities. [Goldberg et al., 2007, pp. 151-152] Jester will recall that Haselbush asks him: “What if a plane were to come here? It’s just a thought that people have had. What if it were to occur here?” Jester replies: “Hopefully it is not going to happen here. What can you do to defend a building against a plane?” [Murphy, 2002, pp. 244] According to the Defense Department’s own book about the Pentagon attack, before returning to his office Jester meets with his deputy, John Pugrud, and directs him to notify the DPS Communications Center to raise the Terrorist Force Protection Condition. This ranges from Normal up through four higher levels, Alpha to Delta. But Jester only instructs that it be raised one level, from Normal to Alpha, which means a general threat of possible terrorist activity exists that requires enhanced security. [Goldberg et al., 2007, pp. 152] It requires spot-inspections of vehicles and increased police patrols. [Washington Post, 9/16/2001] In one account, Jester will recall having instructed Pugrud to increase the threat level earlier, before he’d headed to Cooke’s office. [Murphy, 2002, pp. 244] But other evidence is consistent with him giving this instruction at the later time, minutes before the Pentagon attack. For example, Marine Corporal Timothy Garofola reportedly receives an e-mail shortly before the Pentagon is struck, informing all Defense Department employees that the threat condition remains at Normal (see (Shortly Before 9:37 a.m.) September 11, 2001). [Leatherneck, 11/2001] And Pugrud is reportedly trying to phone the DPS Communications Center about raising the threat level at the very time the Pentagon is hit (see 9:37 a.m. September 11, 2001). [Goldberg et al., 2007, pp. 152]
Shortly After 9:35 a.m. September 11, 2001: Senior Secret Service Agent Tells Colleague about Suspicious Plane Approaching Washington
Danny Spriggs, the assistant director of the Secret Service’s Office of Protective Operations, informs Carl Truscott, the Secret Service special agent in charge of the presidential protective division, that a suspicious aircraft is flying toward the White House. Spriggs is currently in the Director’s Crisis Center (DCC) on the ninth floor of the Secret Service headquarters in Washington, DC (see (9:35 a.m.) September 11, 2001). Truscott is at his office in the Eisenhower Executive Office Building, next to the White House, meeting with three other senior Secret Service agents to discuss security enhancements at the White House (see (9:18 a.m.) September 11, 2001).
Deputy Director Tells Colleague about Approaching Aircraft – Spriggs phoned Truscott after learning that a Secret Service agent he was inquiring about is in Truscott’s office. Now, while he is talking to Truscott, Spriggs is told by Larry Cockell, the deputy director of the Secret Service, who is with him in the DCC, that an aircraft is flying toward the White House and the Secret Service is evacuating the White House. Spriggs passes this information on to Truscott. According to Truscott, Spriggs says that “the intelligence division duty desk [is] reporting Federal Aviation Administration information that a suspicious aircraft [is] coming toward Washington, DC, and that the White House [is] being evacuated.” [United States Secret Service, 10/1/2001; United States Secret Service, 10/1/2001] (Personnel from the intelligence division at Secret Service headquarters are participating in a phone conference with Federal Aviation Administration headquarters, according to the 9/11 Commission Report. Presumably this is where the intelligence division duty desk received its information from. [9/11 Commission, 7/24/2004, pp. 464] )
Agent Says He Will Evacuate the White House – Truscott tells Spriggs he had been unaware of the approaching aircraft, and says he will initiate the evacuations of the White House and the Eisenhower Executive Office Building. Truscott will later recall that while Spriggs is telling him about the approaching aircraft, a Secret Service agent who is with him in his office is receiving “similar FAA information via telephone” from another agent. The name of that agent is unstated. The exact time at which Spriggs tells Truscott about the aircraft flying toward the White House is unclear. Truscott will say that Spriggs called him at 9:43 a.m. However, Spriggs will say he arrived at the DCC at “approximately 9:35 a.m.,” and he apparently called Truscott shortly after that. [United States Secret Service, 10/1/2001; United States Secret Service, 10/1/2001]
Before 9:37 a.m. September 11, 2001: Government Departments in Washington Are Not Evacuated Prior to the Pentagon Attack
Government buildings in Washington, DC, are not evacuated prior to the attack on the Pentagon at 9:37 a.m. As CNN will later describe, even after the attacks on the World Trade Center and the FAA’s warning to the military of a hijacked aircraft apparently heading toward Washington (see 9:21 a.m. September 11, 2001 and (9:24 a.m.) September 11, 2001), “the federal government failed to make any move to evacuate the White House, Capitol, State Department, or the Pentagon.” [CNN, 9/16/2001] Although a slow evacuation of the White House begins at around 9:20 a.m. (see (9:20 a.m.) September 11, 2001), it is not until 9:45 a.m. that the Secret Service orders people to run from there (see (9:45 a.m.) September 11, 2001). [CNN, 9/11/2001; CNN, 9/12/2001; ABC News, 9/11/2002] Other government buildings, including the Capitol (see 9:48 a.m. September 11, 2001), the Justice Department, the State Department, and the Supreme Court (see 10:15 a.m. September 11, 2001), will not be evacuated until between 9:45 a.m. and 10:45 a.m. [US News and World Report, 9/14/2001; US Department of State, 8/15/2002] Robert Bonner, who was recently nominated as Commissioner of Customs, will estimate that he was evacuated from the Treasury Department at “about 9:35 a.m.” [9/11 Commission, 1/26/2004; US Department of Homeland Security, 9/20/2004] But other accounts will say the Treasury Department was not evacuated until after the Pentagon attack. [Associated Press, 9/11/2001; Reuters, 9/11/2001; US Department of State, 9/11/2002] Furthermore, journalist and author Robert Draper will describe, even after the State and Treasury Departments have been evacuated, “no agents thought to take charge of the Commerce Department, which housed 5,000 employees.” [Draper, 2007, pp. 143] According to CNN, prior to the Pentagon attack: “[N]either the FAA, NORAD, nor any other federal government organ made any effort to evacuate the buildings in Washington. Officials at the Pentagon said that no mechanism existed within the US government to notify various departments and agencies under such circumstances [as occur today].” [CNN, 9/16/2001]
9:36 a.m. September 11, 2001: Report of Airliner Approaching White House Sets off ‘Frenzy’ at NEADS
Colin Scoggins, the military liaison at the FAA’s Boston Center, calls NORAD’s Northeast Air Defense Sector (NEADS) to report a low-flying airliner he has spotted six miles southeast of the White House. He can offer no details regarding its identity. The plane is reportedly Flight 77, but as it has its transponder turned off, no one realizes this at the time. The news of the plane “sets off a frenzy.” Major Kevin Nasypany orders Major James Fox, head of the NEADS weapons team, “Get your fighters there as soon as possible!” Staff Sergeant William Huckabone says, “Ma’am, we are going AFIO [emergency military control of the fighters] right now with Quit 2-5 [the Langley Air Force Base fighters]” (see 9:36 a.m. September 11, 2001), and adds, “They are going direct Washington.” [Vanity Fair, 8/1/2006] The Langley fighters will arrive over Washington some time around 10 a.m. (see (Between 9:49 a.m. and 11:00 a.m.) September 11, 2001).
Before 9:37 a.m. September 11, 2001: Washington, DC, Area Hospital Alerted to Approaching Plane; Activates Disaster Plan
The air traffic control tower at Washington Dulles International Airport notifies Inova Fairfax Hospital—the largest hospital in Northern Virginia—that a hijacked aircraft is missing. It passes this information to Dr. Thomas Mayer, the chair of the hospital’s emergency department. [Goldberg et al., 2007, pp. 117] At around 9:32 a.m., air traffic controllers at the FAA’s terminal control facility at Dulles had “observed a primary radar target,” later determined to be Flight 77, “tracking eastbound at a high rate of speed” (see 9:32 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 25; 9/11 Commission, 8/26/2004, pp. 33] Mayer will later recall: “We knew that something was headed towards the national capital area. We didn’t know where. But we knew we needed to get ready. So we immediately went on disaster planning mode.” [Goldberg et al., 2007, pp. 117] The Arlington County After-Action Report indicates the hospital in fact initiates its disaster plan earlier than Mayer suggests, stating: “Inova Fairfax Hospital activated its disaster plan following reports of the World Trade Center attacks. Subsequently, the hospital received emergency notification of a missing airliner from the Washington Dulles International Airport tower.” The hospital cancels elective surgeries until 6:00 p.m. and makes eight trauma teams available within 20 minutes. The regular emergency room is relocated to an alternate site, and nearly 100 nurses and doctors prepare to respond in the event of an attack in the Washington Metropolitan Area. [US Department of Health and Human Services, 7/2002, pp. B3 ] Due to the strategic importance of the region, Inova Fairfax and the other hospitals and clinics in the Washington area are particularly well prepared for mass casualty incidents. They regularly conduct drills to practice for chemical or biological attacks. [Goldberg et al., 2007, pp. 115]
9:36 a.m.-9:39 a.m. September 11, 2001: Emergency Workers See and Promptly Report Low-Flying Flight 77 Approaching the Pentagon and Crashing
Several police officers and firefighters see the low-flying Flight 77 as it approaches the Pentagon and crashes. They quickly report this to their own agencies or to the Arlington County Emergency Communications Center (ECC), which is the focal point of all police and fire 911 calls for the county. [Goldberg et al., 2007, pp. 66] 
Arlington County Police Department Corporal Barry Foust is stopped at traffic lights less than two miles from the Pentagon, and spots the aircraft flying low, then sees a plume of smoke. [Goldberg et al., 2007, pp. 13] He immediately calls the ECC and calmly reports: “I think we just had an airplane crash east of here. Must be in the District area.” [Washington Post, 9/17/2001; Associated Press, 9/18/2001; US Department of Health and Human Services, 7/2002, pp. C6 ] Police Motorcycle Officer Richard Cox is standing near a diner less than a mile from the Pentagon. Hearing a sudden roar, he turns and reportedly sees the plane “directly overhead… no more than a hundred feet off the ground.” [Vogel, 2007, pp. 427] He calls the ECC and reports, “It’s an American Airlines plane headed eastbound over the [Columbia] Pike, possibly headed for the Pentagon.” [Washington Post, 9/17/2001; Associated Press, 9/18/2001; US Department of Health and Human Services, 7/2002, pp. C6 ] Fire Captain Steve McCoy and his crew are traveling north on Interstate 395 in ACFD Engine 101, for a training session in Crystal City. McCoy reportedly sees “a commercial airliner in steep descent, banking sharply to its right before disappearing beyond the horizon,” followed by “a tremendous explosion” and “a massive plume of smoke and fire.” He immediately radioes ECC and reports, “We got a plane down, it looks like in the Crystal City area by the 14th Street Bridge.” Being aware of the attacks on the World Trade Center, he advises that the FBI should be notified, as this is a possible terrorist attack. [US Department of Health and Human Services, 7/2002, pp. A4 ; Goldberg et al., 2007, pp. 66] Officer Mark Bright of the Defense Protective Service (DPS)—the Pentagon’s police force—is manning the security booth at the Pentagon’s Mall entrance, when he hears a loud noise. He will recall: “I saw the plane at the Navy Annex area [a few hundred yards from the Pentagon]. I knew it was going to strike the building because it was very, very low—at the height of the street lights.” As soon as he sees it hit the Pentagon he radioes in his report of the attack, and then speeds in his police cruiser to the crash site, becoming the first officer there. [American Forces Press Service, 9/24/2001; Washington Post, 10/25/2001; Goldberg et al., 2007, pp. 152] Sergeant William Lagasse, also a member of the DPS, is filling up his patrol car at a gas station near the Pentagon. He recalls that he sees an “American Airlines 757… approximately 100 feet above the ground level, maybe 60 feet in front of me.” He watches the plane crash into the Pentagon. His first reaction is to call the DPS Communications Center and state, “An aircraft has just flown into the side of the building.” He then grabs his medical bag and dashes to the crash scene. [Washington Post, 10/25/2001; Library of Congress, 12/4/2001] Alan Wallace and Mark Skipper of the Fort Myer Fire Department are manning the fire station by the Pentagon heliport, and are outside checking their truck. Wallace glances up and sees the plane coming at them, and the two men then dive for cover (see 9:37 a.m. September 11, 2001). Wallace promptly radioes the fire department headquarters at Fort Myer, and reports that an airliner has hit the west side of the Pentagon. [Goldberg et al., 2007, pp. 65]
Partly due to these calls, many emergency responders quickly learn of the crash and are able to arrive at the Pentagon within minutes of it (see 9:40 a.m.-9:43 a.m. September 11, 2001). [Goldberg et al., 2007, pp. 66] Some fire and rescue units from Arlington County and elsewhere also respond—self-dispatching from stations or diverting from other destinations—after hearing Captain McCoy’s radio message to the ECC. [US Department of Health and Human Services, 7/2002, pp. A4 ]
Shortly Before 9:37 a.m. September 11, 2001: Fire Department Responds to Alarm from USA Today ‘Twin Towers’ Building, near Pentagon
Arlington County firefighters are dispatched in response to a fire alarm at the USA Today building, located just a few miles down the road from the Pentagon, though whether there is actually a fire there is unclear. [USA Today, 9/13/2001; McClatchy Washington Bureau, 2008] The USA Today complex, in the Rosslyn area, includes the two tallest high-rise buildings in the county, which are in fact known as the “Twin Towers.” [Washington Business Journal, 9/7/2001; Creed and Newman, 2008, pp. 9] The building’s managers had been worried that the complex could be a terrorist target, and called the Arlington County Emergency Communications Center (ECC), asking if they should evacuate (see (9:04 a.m.-9:36 a.m.) September 11, 2001). According to Assistant Chief James Schwartz of the Arlington County Fire Department, “Shortly after that, we had a fire response for alarm bells at the USA Today building.” Schwartz is dispatched to the building, but before he leaves his office, word is received about the Pentagon attack, so he heads to the Pentagon instead. [McClatchy Washington Bureau, 2008; Creed and Newman, 2008, pp. 48-49]
Fire Chief Believes Alarm Activated to Facilitate Evacuation – Schwartz will later reflect, “I’ve always suspected that people who were evacuating [the USA Today building] decided that they would pull the fire alarm in order to get everybody out of the building, and that initiated a response on our part.” [McClatchy Washington Bureau, 2008] However, according to USA Today spokesman Steve Anderson, who is at the complex, employees of USA Today and its parent company Gannett only begin evacuating the building after the Pentagon attack occurs. Westfield Realty, the company that owns the building, asks all the tenants to evacuate at about 11:00 a.m., but most will already have left by then. [Washington Business Journal, 9/11/2001; Washington Business Journal, 9/14/2001]
Report Apparently Describes Same Incident – The alarm at the USA Today building may be the same incident as is later described in the Arlington County After-Action Report on the emergency response to the Pentagon attack. The report states that, “just one minute before the Pentagon crash,” several fire and medical units are dispatched “to an apartment fire at 1003 Wilson Boulevard in Rosslyn” (see (Shortly Before 9:37 a.m.) September 11, 2001). [US Department of Health and Human Services, 7/2002, pp. A9 ] The address of the USA Today complex is reported as being “1000 and 1110 Wilson Blvd.,” suggesting this is the same building as where the “apartment fire” is reported to be. [Washington Business Journal, 9/7/2001] The first engine to arrive in response to the apartment fire reports that it is already out. [US Department of Health and Human Services, 7/2002, pp. A9 ]
News Reports of Fire – In the aftermath of the attack on the Pentagon, news reports will—apparently incorrectly—describe a fire at the USA Today building. At 9:46 a.m., local radio station WTOP will report, “We’re hearing from a caller who says she is eyewitness to another hit here in town; the USA Today building may also be on fire in addition to the Pentagon.” [Broadcasting and Cable, 8/26/2002] The Washington Post will describe, “The USA Today building in Rosslyn was supposedly enveloped in smoke.” [Washington Post, 9/11/2001] But the Associated Press states that “Radio reports about an explosion at the USA Today building in Rosslyn were false.” [Associated Press, 9/11/2001]
9:36 a.m.-10:06 a.m. September 11, 2001: United Airlines Crisis Center Watches Flight 93 on Radar until It Crashes
At the United Airlines crisis center, at its headquarters outside Chicago, staff members watch Flight 93’s radar track until the plane crashes. United Airlines’ senior management has started to gather in the theater-like crisis center, a room that resembles NASA’s Mission Control. Although the airline still has hundreds of flights in the air, officials have highlighted only Flight 93’s path on the large Aircraft Situation Display screen. Even after the plane’s transponder has been switched off (see (9:40 a.m.) September 11, 2001), the flight can still be tracked, but officials can no longer determine its altitude. They watch as the plane’s speed fluctuates wildly while it heads toward Washington. Hank Krakowski, United Airlines’ director of flight operations, will later recall: “We knew what was going on. We could see the airplane headed toward the capital. We were wondering whether the military was going to intervene or not.” Those in the crisis center see Flight 93’s radar track stop moving at the time it crashes. A dispatcher determines the latitude and longitude of its last position and reports that it was south of Johnstown in Pennsylvania, about 120 miles from Washington. [Wall Street Journal, 10/15/2001; Longman, 2002, pp. 77-78 and 214; USA Today, 8/13/2002]
9:36 a.m. September 11, 2001: Airline Dispatchers Learn Flight 93 Is Heading for Washington, Offer It Assistance
United Airlines flight dispatcher Ed Ballinger is informed that Flight 93, which he is responsible for monitoring, is heading for Washington, DC. At the United Airlines System Operations Control (SOC) center, near Chicago, dispatch manager Mike Barber tells Ballinger that Flight 93 is “off track, heading for DC.” The aircraft has just reversed course (see (9:36 a.m.) September 11, 2001) and, having learned that it is not responding to FAA communications (see (9:30 a.m.) September 11, 2001), officials at United Airlines headquarters now believe it has been hijacked. [Wall Street Journal, 10/15/2001; 9/11 Commission, 7/24/2004, pp. 456; 9/11 Commission, 8/26/2004, pp. 41] Also at this time, a United dispatcher who is assisting Ballinger sends a text message to Flight 93, asking, “How’s the wx [weather][?]” and, “Can dispatch be of any assistance?” No response is received. [9/11 Commission, 1/27/2004; 9/11 Commission, 8/26/2004, pp. 41]
