After being focused on Flight 11, Dave Bottiglia, an air traffic controller at the FAA’s New York Center, first notices problems with Flight 175. [MSNBC, 9/11/2002; 9/11 Commission, 7/24/2004, pp. 21] Both Flight 11 and Flight 175 have been in the airspace that Bottiglia is responsible for monitoring (see 8:40 a.m. September 11, 2001 and (8:42 a.m.-8:46 a.m.) September 11, 2001). Bottiglia has just watched Flight 11’s radar blip disappear, which means the plane has dipped below his radar’s coverage area, so is below 2,000 feet. But he does not yet realize it has crashed. He says aloud, “Well, we know he’s not high altitude anymore.” [MSNBC, 9/11/2002; Spencer, 2008, pp. 37] Around this time, Flight 175’s transponder changes twice in the space of a minute (see 8:46 a.m.-8:47 a.m. September 11, 2001).
Conflicting Accounts – According to MSNBC, “within seconds” of losing Flight 11’s blip, “Bottiglia has another unexpected problem.” While looking for Flight 11, he realizes that Flight 175 is also missing, and “instinctively… knows the two [planes] are somehow related.” He asks another controller to take over all of his other planes. [MSNBC, 9/11/2002] But according to the 9/11 Commission’s account, Bottiglia is still trying to locate Flight 11 after it crashes, and so it is not until 8:51 a.m. that he notices the problem with Flight 175 (see 8:51 a.m.-8:53 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 21]
‘An Intruder over Allentown’ – Around the time Flight 175 changes its transponder code, air traffic controller Curt Applegate, who is sitting at the radar bank next to Bottiglia’s, sees a blip that might be the missing Flight 11. He shouts out: “Look. There’s an intruder over Allentown.” According to the Washington Post, “In air traffic jargon, an ‘intruder’ is a plane with an operating transponder that has entered restricted airspace without permission.” In fact, it is the missing Flight 175. [Washington Post, 9/17/2001; MSNBC, 9/11/2002] However, these accounts make no mention of NORAD being notified about the problems with Flight 175 at this time. But according to a NORAD timeline released shortly after 9/11, NORAD’s Northeast Air Defense Sector (NEADS) was alerted about Flight 175 by the FAA several minutes earlier, at 8:43 a.m. (see 8:43 a.m. September 11, 2001). [North American Aerospace Defense Command, 9/18/2001]
8:47 a.m.-9:20 a.m. September 11, 2001: Mayor Giuliani Learns of First WTC Crash, Yet Doesn’t Go to Special Emergency Command Center
New York City Mayor Rudolph Giuliani is promptly informed of the first WTC crash while having breakfast at the Peninsula Hotel on 55th Street. He later claims that he goes outside and, noticing the clear sky, immediately concludes, “It could not have been an accident, that it had to have been an attack. But we weren’t sure whether it was a planned terrorist attack, or maybe some kind of act of individual anger or insanity.” Only after the second plane hits at 9:03 will he be convinced it is terrorism. After leaving the hotel, he quickly proceeds south. In his 2002 book, Leadership, he will claim that he heads for his emergency command center. This $13 million center is located on the 23rd floor of Building 7 of the WTC, and was opened by Giuliani in 1999, specifically for coordinating responses to emergencies, including terrorist attacks (see June 8, 1999). Referring to it, he writes, “As shocking as [the first] crash was, we had actually planned for just such a catastrophe.” At around 9:07 a.m., Giuliani meets Police Commissioner Bernard Kerik at Barclay Street, on the northern border of the WTC complex. [Giuliani, 2002, pp. 3-6; 9/11 Commission, 5/19/2004; Barrett and Collins, 2006, pp. 7] Yet they do not go to the command center. According to Kerik, “The Mayor and I… determined early on that the City’s pre-designated Command and Control Center… was unsafe because of its proximity to the attack.” [9/11 Commission, 5/18/2004 
] Instead, they head to West Street, where the fire department has set up a command post, and arrive there at around 9:20 a.m. However, in his private testimony before the 9/11 Commission in 2004, Giuliani will apparently change his story, claiming he’d never even headed for his command center in the first place. He says, “Even if the Emergency Operations Center had been available, I would not have gone there for an hour or an hour and a half. I would want to spend some time at the actual incident, at operations command posts.” [9/11 Commission, 5/19/2004; Barrett and Collins, 2006, pp. 44-45 and 340-341] Other accounts indicate that the emergency command center is mostly abandoned from the outset, with emergency managers instead heading to the North Tower (see (Soon After 8:46 a.m.-9:35 a.m.) September 11, 2001).
8:47 a.m.-10:28 a.m. September 11, 2001: Hundreds Die in WTC Elevators, as Elevator Mechanics Flee
During the 9/11 catastrophe, around 200 people die in the WTC’s elevators without getting help from elevator mechanics, according to an in-depth study later performed by USA Today. Some of the victims are burned by the initial explosion, some die as the elevator cars plummet when their cables are severed, and some are stuck and perish in the collapse. USA Today will say it “could not locate any professional rescues of people stuck in elevators. The Fire Department of New York and the Port Authority also could not cite successful rescues.” After the North Tower is hit, most of the WTC’s 83 elevator mechanics gather in the lobby of the South Tower, but when the second plane hits, they evacuate. In contrast, a passing elevator mechanic from another company runs into the WTC and dies trying to free trapped passengers. USA Today will comment: “When the World Trade Center was bombed in 1993, Otis Elevator’s mechanics led the rescue of 500 people trapped in elevators. Some mechanics were dropped onto the roofs of the Twin Towers by helicopter. Others, carrying 50-pound oxygen tanks on their backs, climbed through smoke to machine rooms high in the towers. On Sept. 11, the elevator mechanics—many of the same men involved in the rescues in 1993—left the buildings after the second jet struck, nearly an hour before the first building collapsed.” Although ACE Elevator, the local company which won the WTC contract from Otis in 1994, will say it was acting in accordance with procedure, USA Today will note: “The departure of elevator mechanics from a disaster site is unusual. The industry takes pride in rescues. In the Oklahoma City bombing in 1995, elevator mechanics worked closely with the firefighters making rescues.” Robert Caporale, editor of Elevator World will say, “Nobody knows the insides of a high-rise like an elevator mechanic. They act as guides for firefighters, in addition to working on elevators.” The Port Authority will also say that their departure was in conflict with the emergency plan. “There was no situation in which the mechanics were advised or instructed to leave on their own.” [USA Today, 12/19/2001; USA Today, 9/4/2002]
8:47 a.m.-9:36 a.m. September 11, 2001: DIA Personnel at the Pentagon Respond to the Attacks in New York but Do Not Evacuate
Defense Intelligence Agency (DIA) employees at the Pentagon take action in response to the terrorist attacks in New York, but they stay in their offices rather than evacuating and so a number of them will be killed when the Pentagon is hit. Sometime after the first hijacked plane crashed into the World Trade Center, at 8:46 a.m. (see 8:46 a.m. September 11, 2001), DIA analysts who are “[t]rained for this kind of emergency,” according to journalists Eric Schmitt and Thom Shanker, promptly respond to the incident. One group of them starts assessing what has happened; another group starts looking through classified intelligence reports in search of clues about how the attack was planned and conducted; and another group contacts colleagues at the CIA and other intelligence agencies to share information. [Schmitt and Shanker, 2011, pp. 18-19; Defense Intelligence Agency, 9/11/2015] After the second hijacked plane hits the WTC, at 9:03 a.m. (see 9:03 a.m. September 11, 2001), DIA personnel at the Pentagon “swung into crisis management,” Randall Blake, the DIA’s current intelligence terrorism chief, will later recall. Blake is called by his office chief at DIA headquarters at Bolling Air Force Base in Washington, DC. The two men discuss the situation and Blake’s office chief dispatches five or six people to the Pentagon. After reports start coming in stating that the first plane to hit the WTC was hijacked, Blake is summoned to a meeting with Rear Admiral Lowell Jacoby, the director of intelligence for the Joint Staff. At the meeting, Jacoby issues a set of concise instructions on how the unfolding crisis will be dealt with. [Blake, 2012, pp. 2 ] Apparently, no attempt is made to evacuate DIA employees from the Pentagon before the building is attacked. When Flight 77 hits it at 9:37 a.m., the plane will crash through the DIA’s Office of the Comptroller on the first floor of the building’s C Ring, killing seven employees there (see 9:37 a.m. September 11, 2001). [Washington Post, 3/11/2002; Defense Intelligence Agency, 9/11/2015]
Shortly After 8:46 a.m. September 11, 2001: DC Air National Guard Officers Learn of First WTC Crash, Think It Is an Accident
Pilots and officers with the District of Columbia Air National Guard (DCANG) are notified of the first plane hitting the World Trade Center, but mistakenly assume this must have been an accident and continue with a meeting they are holding. [Rasmussen, 9/18/2003; 9/11 Commission, 3/11/2004 ; Spencer, 2008, pp. 122] The 113th Wing of the DC Air National Guard, which includes the 121st Fighter Squadron, is based at Andrews Air Force Base in Maryland, 10 miles southeast of Washington. [District of Columbia Air National Guard, 7/24/2001; GlobalSecurity (.org), 8/21/2005; GlobalSecurity (.org), 1/21/2006]
Pilots and Flight Managers in Meeting – Some DCANG officers are currently in a conference room at their unit at Andrews, conducting the weekly scheduling meeting, where plans for the upcoming week are discussed. According to Captain Brandon Rasmussen, a pilot who is also the chief of scheduling with the unit, about five or six people are in the meeting. [Rasmussen, 9/18/2003; 9/11 Commission, 3/11/2004 ] As well as Rasmussen, those present include Major David McNulty, the senior intelligence officer of the 113th Wing; pilots Marc Sasseville and Daniel Caine; and a new officer, Mark Valentine.
Officers Think Crash Is an Accident – An intelligence officer interrupts the meeting and says a plane has just flown into the WTC. However, the meeting participants assume the crash is an accident involving a small aircraft. [9/11 Commission, 3/8/2004 ; 9/11 Commission, 3/11/2004 ; Spencer, 2008, pp. 122] Rasmussen will later recall: “[A]ll of us in the meeting kind of looked at each other and looked outside the window, it was clear blue skies. It doesn’t get any more flying weather than that. So we thought, ‘What kind of a moron can’t see those big buildings right in front of them?’ We all figured it was just some light civil aircraft… little Cessnas, Piper Cubs, or whatever, someone doing some sightseeing flying up and down the Hudson and just not paying attention where he was going.” Therefore, “we continued on with the meeting, thinking we’d catch the news clips later on in the day.” The scheduling meeting will continue until its participants learn of the second plane hitting the WTC and realize this is a terrorist attack (see (9:04 a.m.) September 11, 2001). [Rasmussen, 9/18/2003; 9/11 Commission, 3/11/2004 ; Spencer, 2008, pp. 122-123]
Some at Base Suspicious about Crash – However, according to the Washington Post, at least some individuals with the DC Air National Guard are “immediately suspicious” upon hearing of the first crash. Pilot Heather Penney Garcia will recall having wondered, “How do you make a mistake like that?” (Penney Garcia is at the 121st Fighter Squadron headquarters at Andrews, though whether she is attending the scheduling meeting is unstated.)
Only Four DCANG Pilots Available – Members of the 121st Fighter Squadron have just returned from “Red Flag,” a major training exercise in Nevada (see Late August-September 8, 2001). Most of the squadron’s pilots, who fly commercial planes in their civilian lives and are involved with the unit on only a part-time basis, are consequently away from the base on this day, either back at their airline jobs or on leave, according to different accounts. [Washington Post, 4/8/2002; 9/11 Commission, 2/27/2004; Spencer, 2008, pp. 156] Of the seven pilots the squadron has available at the base today, three have just taken off for a training mission over North Carolina (see 8:36 a.m. September 11, 2001), meaning only four available pilots are left at the base. [9/11 Commission, 2/17/2004; 9/11 Commission, 2/27/2004; 9/11 Commission, 3/8/2004 ; 9/11 Commission, 3/11/2004 ]
DCANG Not Part of NORAD Air Defense Force – The DC Air National Guard flies the F-16 Fighting Falcon jet fighter, and its mission includes providing “capable and ready response forces for the District of Columbia in the event of a natural disaster or civil emergency.” [DC Military (.com), 6/2001; GlobalSecurity (.org), 8/21/2005] Unlike other Air National Guard units, it reports to the president, instead of a state governor. It works closely with Secret Service agents who are across the runway at Andrews Air Force Base, in the Air Force One hangar. [Washington Post, 4/8/2002; Vogel, 2007, pp. 445] According to Aviation Week and Space Technology magazine, the 121st Fighter Squadron is “not standing alert on Sept. 11” because the DC Air National Guard is “not assigned to the North American Aerospace Defense Command air defense force.” [Aviation Week and Space Technology, 9/9/2002]
After 8:46 a.m. September 11, 2001: United Airlines Control Center Experiences Communication Problems for Two Hours
Those at United Airlines’ System Operations Control (SOC) center, near Chicago, have serious problems communicating with others outside their building, particularly using e-mail, for a period of about two hours. This is according to Ed Soliday, United Airlines’ vice president of safety and security, who is involved with the airline’s response to the terrorist attacks after arriving at the SOC at around 9:35 a.m. Soliday will tell the 9/11 Commission that, on this day, United Airlines “lost e-mail capability and some of their phone and cell service.” This, he will say, is “because everyone was on the phone trying to ‘call their best friend’ to talk about what was happening,” presumably meaning that the national telecommunications infrastructure has become overloaded due to increased traffic. Soliday will add, “For a couple of hours, trying to communicate out of the [SOC] building was impossible.” [9/11 Commission, 11/21/2003 ] Soliday apparently does not state the particular time period over which United Airlines experiences these communication problems. However, it appears they may begin around the time of the first attack, since, according to the 9/11 Commission, shortly before 9:00 a.m., a United dispatch manager is unable to reach top company officials because the airline’s pager system “was not working” (see (Shortly After 8:48 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 21-22]
Between 8:47 a.m. and 8:55 a.m. September 11, 2001: Deputy Fire Safety Director Orders Evacuation of WTC’s North Tower, but Announcement Is Unheard
Lloyd Thompson, the deputy fire safety director in the North Tower of the World Trade Center, attempts to make an announcement instructing workers to evacuate the building, but the public address system was damaged by Flight 11 hitting the tower and so no one hears it. Thompson works for OCS Security, which holds the security contract for the WTC, and is on duty at the fire command desk in the ground-floor lobby of the North Tower. There, he is responsible for watching the building’s various security and fire safety computer systems. [9/11 Commission, 5/18/2004 ; New York Times, 5/22/2004; Dwyer and Flynn, 2005, pp. 45]
Announcements Attempted, but Public Address System Is Damaged – After Flight 11 hits the North Tower (see 8:46 a.m. September 11, 2001), following protocol, Thompson initially tries issuing instructions to just the floors of the building that have generated “computerized alarms,” according to the 9/11 Commission Report. In an announcement, he advises workers on those floors “to descend to points of safety—at least two floors below the smoke or fire—and to wait there for further instructions.” He then tries ordering the full evacuation of the tower over the public address system. [9/11 Commission, 7/24/2004, pp. 286] However, Thompson’s attempts at issuing instructions to people in the building are unsuccessful. The 9/11 Commission will state, “[T]he public address system was damaged [by the impact of the plane] and no one apparently heard the announcement.” [9/11 Commission, 5/18/2004 ]
Time of Attempted Evacuation Order Unclear – It is unclear when Thompson first tries ordering the full evacuation of the North Tower. He will tell the 9/11 Commission that he does so “within about 10 minutes” of Flight 11 hitting the building, meaning before 8:56 a.m. The reason for the delay, according to the 9/11 Commission Report, is that, although he was “immediately aware that a major incident had occurred” after Flight 11 hit the tower, Thompson “did not know for approximately 10 minutes that a commercial jet had directly hit the building.” However, when he is contacted by the deputy fire safety director in the South Tower at 8:49 a.m., just three minutes after the crash, Thompson tells his colleague that there has been “a major explosion” at the WTC, which, he says, “might be an aircraft” (see 8:49 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 286-287; Dwyer and Flynn, 2005, pp. 27] Furthermore, George Tabeek, the Port Authority’s security manager for the WTC, will later say that “he called in to his fire safety command”—presumably referring to the fire command desks in the Twin Towers—“right after the first plane struck” and gave instructions “to evacuate the North Tower” (see Shortly After 8:46 a.m. September 11, 2001). [New Jersey Star-Ledger, 9/6/2011] Additionally, according to the 9/11 Commission Report, when fire department chiefs arrive in the lobby of the North Tower, Michael Hurley, the Port Authority’s fire safety director, tells them “that the full building evacuation announcement had been made within one minute of the building being hit.”
Automated Announcement Tells Workers to Stay in Offices – Around the time that Thompson is attempting to instruct people to evacuate the North Tower, the deputy fire safety director in the South Tower makes an announcement over that building’s public address system, advising workers to stay in—or return to—their offices, rather than evacuate (see (8:50 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 286-288] According to some security officers, an automated announcement was activated when Flight 11 crashed, which similarly instructs workers in the North Tower to stay in their offices, although it is unclear how many people hear that announcement (see Shortly After 8:46 a.m. September 11, 2001). [Newsday, 9/10/2002]
After 8:46 a.m. September 11, 2001: Software Company Reconstructs Paths of Four Hijacked Planes
A Fairfax, Virginia company that makes computer software that tracks and records the flight paths of planes helps media companies and airlines to reconstruct the paths of all four of the hijacked aircraft. [Washington Business Journal, 9/11/2001; Washington Post, 9/13/2001] Flight Explorer sells an Internet-accessible application that provides constantly updated information on the positions of aircraft in flight. It uses radar feeds that the FAA collects from control centers across the US. [Business Wire, 6/16/2000; St. Petersburg Times, 8/12/2001] All of Flight Explorer’s employees begin sorting through its data “after the first crash [of Flight 11] was reported,” so presumably this is at around 8:50 a.m. Whether any particular agency, such as the FAA, requests this or they do it of their own initiative is unknown. Although there are some 4,000 planes in the air above the US at the time of the attacks, the company is quickly able to pinpoint the paths of all four hijacked aircraft. It then creates charts and animated videos of the four flights’ actual and intended routes. About 12 news agencies, including all the major networks, request these animated illustrations. [Washington Business Journal, 9/11/2001; Washington Post, 9/13/2001] Flight Explorer is apparently unhindered by the fact that flights 11 and 93 have their transponders turned off during the hijackings. Its reconstruction of Flight 77’s path ends, however, at 8:57, around the time that aircraft’s transponder goes off and it disappears from controllers’ radar screens (see (8:56 a.m.-9:05 a.m.) September 11, 2001). Yet the 9/11 Commission will later say that, despite this disappearance, “Radar reconstructions performed after 9/11 reveal that FAA radar equipment tracked the flight from the moment its transponder was turned off.” Why the Flight Explorer illustration does not therefore show the rest of Flight 77’s journey is not clear. [AVweb, 9/11/2001; 9/11 Commission, 6/17/2004 ] Until a few years back, Flight Explorer was the only company that recorded flight paths. Since the 1999 death of golfer Payne Stewart (see October 25, 1999) the FAA has also been recording these paths. [Washington Business Journal, 9/11/2001] The final report of the 9/11 Commission will make no mention of the Flight Explorer flight path recordings. [9/11 Commission, 7/24/2004, pp. 222]
After 8:46 a.m. September 11, 2001: Emergency Response Plans Activated by Officials, Not by President Bush
President Bush will say in a speech later that evening, “Immediately following the first attack, I implemented our government’s emergency response plans.” [US President, 9/17/2001] However, the Wall Street Journal reports that lower level officials activate CONPLAN (Interagency Domestic Terrorism Concept of Operations Plan) in response to the emerging crisis. CONPLAN, created in response to a 1995 Presidential Decision Directive issued by President Clinton and published in January 2001, details the responsibility of seven federal agencies if a terrorist attack occurs. It gives the FBI the responsibility for activating the plan and alerting other agencies. Bush in fact later states that he doesn’t give any orders responding to the attack until after 9:55 a.m. [US Government, 1/2001; Wall Street Journal, 3/22/2004 ]
8:48 a.m. September 11, 2001: National Communications System Coordinating Center Activated in Response to Attacks
The National Coordinating Center (NCC) in Arlington, Virginia, which is the operational arm of the National Communications System (NCS), is activated in response to the terrorist attacks and supports the recovery efforts. [9/11 Commission, 3/16/2004 ] The NCS is a relatively small government agency that works to ensure the availability of critical communications networks during times of crisis. [Verton, 2003, pp. 136]
Center Conducts Non-Stop Operations – An NCS publication will later describe, “Immediately,” in response to the attacks, “the NCC began non-stop operations to support NS/EP [national security and emergency preparedness] communications between federal, state, and local responders, to restore damaged communications lines in Arlington, Virginia, and New York City, and to provision new lines for the recovery and investigation activities.” The NCC operates at four sites: the NCC itself, the Federal Emergency Management Agency (FEMA), the Defense Department’s Global Network Operations Support Center headquarters, and a remote “continuity of operations” location. Brenton Greene, the director of the NCS, goes to his “Continuity of Government” site, where personnel operate around the clock to monitor the status of the telecommunications network, and coordinate priorities and repairs. The NCS, which is part of the Department of Defense, also deploys military reservists to three FEMA regional operations centers.
Time Center Activated at Unclear – Greene will tell the 9/11 Commission that the NCC is activated at 8:48 a.m. [National Communications System, 2004, pp. 56 ; 9/11 Commission, 3/16/2004 ] However, other accounts will indicate that the center is not activated until later on. According to journalist and author Dan Verton, Greene—who is attending a briefing on the terrorist threat to the US’s telecommunications infrastructure, apparently at the NCC—initially believes the first plane hit the World Trade Center by accident, and therefore orders the briefing to continue (see 8:00 a.m.-9:03 a.m. September 11, 2001). It is only when the second plane hits the WTC at 9:03 a.m. that he realizes “there was some threat,” and responds to the crisis. [Verton, 2003, pp. 139, 141] Counterterrorism “tsar” Richard Clarke will write that he himself gives the instruction to activate the NCS, at around 12:30 p.m. Then, according to Clarke, his colleague Paul Kurtz calls Greene and instructs him to tell all the major telephone companies that “they need to support Verizon.” [Clarke, 2004, pp. 19-20]
Center Coordinates Emergency Communications during Crises – The NCS was established by President John F. Kennedy in 1963, in order to provide better communications support to critical government functions during emergencies. An executive order signed by President Ronald Reagan in 1984 broadened the NCS’s capabilities, and listed its duties as “the planning for and provision of national security and emergency preparedness communications for the federal government under all circumstances, including crisis or emergency, attack, recovery, and reconstitution.” [US President, 4/3/1984; National Communications System, 10/21/2007; CNET News, 1/16/2009] The NCS consists of 22 federal agencies, 100 full-time civilian employees, and 10 military employees. [Computerworld, 11/7/2002] The mission of the NCC is to assist “in the initiation, coordination, restoration, and reconstitution of national security or emergency preparedness telecommunications services or facilities under all conditions of crisis or emergency.” The center is composed of members from the US government and the telecommunications industry. [US President, 4/3/1984; National Communications System, 3/2001, pp. 4, 6 ] There are 150 private sector contractors from 21 companies working at the NCC. [Computerworld, 11/7/2002]
