Personnel at United Airlines’ headquarters, near Chicago, are subjected to a surprise training exercise in which they are led to believe that one of their planes has crashed, and their experience with this exercise allegedly means they will be better able to respond to the 9/11 attacks. [USA Today, 8/12/2002; 9/11 Commission, 11/20/2003 pdf file; Studdert, 5/26/2015 pdf file; Dubuque Telegraph Herald, 11/12/2015]
Manager Is Concerned that the Airline Is Unprepared for an Accident - Andy Studdert, United Airlines’ chief operating officer, has been concerned that, since it hasn’t suffered a real accident in over 15 years, United Airlines is unprepared to respond properly should one occur now. “I was worried we’d become cocky,” he will later comment. “We thought it couldn’t happen to us.” Around March this year, therefore, he told the airline’s other managers, “One of these days, I’m gonna come in here and I’m gonna do a no-notice drill.” [Center for Values-Driven Leadership, 3/15/2012; Center for Values-Driven Leadership, 4/26/2012] A “no-notice” drill is an exercise that is conducted without its participants being given any formal advance notice of when it will occur. [US Department of Justice, 5/21/2000; Inglesby, Grossman, and O'Toole, 2/1/2001; Oak Ridge Institute for Science and Education, 10/15/2011]
Pilot Is Told to Pretend His Plane Is Experiencing an Emergency - Today, Studdert holds this no-notice exercise. Only a few people know about it in advance. Studdert tells a United Airlines employee who he will refer to as his “safety guy” to contact the pilot of a flight to Australia and give them some instructions. The pilot is therefore told he needs to call in during his flight and report an emergency. He should say there is an “uncontained number three engine failure, rapid descent, decompression,” but stop talking halfway through the word “decompression” and then go silent. He should also turn off the plane’s transponder. [Center for Values-Driven Leadership, 3/15/2012; Dubuque Telegraph Herald, 11/12/2015] (A transponder is a device that sends an aircraft’s identifying information, speed, and altitude to air traffic controllers’ radar screens. [Washington Post, 9/16/2001] )
Airline Personnel Think One of Their Planes Has Crashed - The simulated emergency takes places this afternoon. At around 2 o’clock, Studdert is interrupted by his secretary, Maryann Irving, who rushes into his office and tells him a Boeing 747 has lost contact while flying over the Pacific Ocean. In response, he runs to the airline’s operations center. [Wall Street Journal, 10/15/2001; Center for Values-Driven Leadership, 3/15/2012] Airline employees believe the apparently troubled aircraft has crashed. Some of them are upset and some become physically ill. [Dubuque Telegraph Herald, 11/12/2015] “There are people throwing up in the hall; there are people crying; there are people just staring out the windows,” Studdert will describe.
Personnel Think the Crisis Is Real for 30 Minutes - Since no one in the operations center is able to contact the apparently troubled aircraft, Studdert opens the airline’s crisis center. [Center for Values-Driven Leadership, 3/15/2012] The crisis center, according to journalist and author Jere Longman, is “a terraced, theater-like room that resembled NASA’s Mission Control.” [Longman, 2002, pp. 77] Opening it, according to Studdert, is a significant course of action. When this happens, everyone working for the airline becomes responsible either for running the airline or acting to support the management of the emergency. This means that “3,000 people are put on an immediate activation.” [Center for Values-Driven Leadership, 4/23/2012] United Airlines employees believe one of their planes has crashed for about 30 minutes and then Studdert reveals that the apparent catastrophe is just an exercise scenario. [USA Today, 8/12/2002] He gets on the crisis center’s communications link, which, he will say, “has got 170 stations and people all over the country, all over the world,” and announces, “This has been a no-notice drill; there is no event; everything’s fine.”
Employees Are Furious about the Exercise - The reaction to the exercise in the days after it takes place will be particularly bitter and Studdert will face severe criticism for running it. “I had the board members calling; I had the unions demanding I be fired; I had people telling me I’m the most evil person in the world,” he will recall. [Center for Values-Driven Leadership, 3/15/2012; Center for Values-Driven Leadership, 4/26/2012] Some employees “wanted to kill me,” he will say.
Exercise Has Similarities to the Situation Experienced on September 11 - It is unclear whether Studdert’s exercise has a beneficial or a detrimental effect on the ability of United Airlines to respond to the hijackings 12 days later, on September 11. Studdert will claim that it prepares employees to manage the events of September 11 and reveals weaknesses, such as outdated phone numbers, which are quickly corrected. [Center for Values-Driven Leadership, 4/26/2012; Dubuque Telegraph Herald, 11/12/2015] “It’s amazing, after 9/11… how many people came up to me and thanked me [for running the exercise], because we were ready,” he will say. [Center for Values-Driven Leadership, 3/15/2012] It is possible, however, that it will cause some United Airlines employees to initially think the reports about the terrorist attacks on September 11 are part of another exercise, although accounts are contradictory (see (8:50 a.m.-9:03 a.m.) September 11, 2001). [USA Today, 8/12/2002; Chicago Tribune, 7/16/2003] The scenario of Studdert’s exercise in fact has some similarities with the situation that operations center personnel have to deal with on September 11. On that day, communication with Flight 175—the first of the two United Airlines planes that are hijacked—will be lost (see 8:51 a.m.-8:53 a.m. September 11, 2001) and the plane will have its transponder code changed, although the transponder will not be turned off (see 8:46 a.m.-8:47 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 20-21] Communication will subsequently be lost with Flight 93—the second United Airlines plane to be hijacked (see 9:27 a.m. September 11, 2001 and (9:29 a.m.) September 11, 2001)—and that plane’s transponder will be turned off (see (9:40 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 38-39, 43]
Crisis Center Holds Quarterly Exercises - The United Airlines crisis center usually runs exercises four times a year. Most of these deal with safety issues, but security scenarios are also rehearsed, according to Ed Soliday, the airline’s vice president of safety and security. Typically, the 9/11 Commission will be told, these exercises “are scripted” and based around an act of bioterrorism or an international incident. United Airlines has also practiced hijacking scenarios, according to Soliday, although none of these dealt with the threat of an aircraft being used as a weapon.

Captain Charles Leidig. 
Captain Charles Leidig. [Source: US Navy]Brigadier General Montague Winfield, the deputy director for operations (DDO) in the National Military Command Center (NMCC) at the Pentagon, leaves his post to attend a pre-scheduled meeting, allowing a colleague, who only recently qualified to take over his position, to stand in for him, and not returning to his post until after the terrorist attacks have ended. [9/11 Commission, 7/21/2003 pdf file; 9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 6/17/2004]
Winfield Attends Air Force-Convened Meeting - Winfield leaves his post to attend what a 9/11 Commission memorandum will call “an unrelated, closed-door personnel meeting convened by the Air Force to discuss the rating of Air Force officers.” [9/11 Commission, 7/21/2003 pdf file] Another Commission memorandum will state that this meeting is a “session for general officers who rated Air Force officers.” It is unclear whether the meeting takes place somewhere in the NMCC or outside the center. The Commission memorandum will only say that it takes place “elsewhere in [Joint Chiefs of Staff] spaces.” At least one of the NMCC’s other qualified DDOs, Brigadier General Norman Seip, is also attending it.
Winfield Asked Colleague to Replace Him on Previous Day - Winfield is temporarily replaced as DDO by Captain Charles Leidig. Leidig only joined the operations directorate of the Joint Chiefs of Staff in July 2001, when he assumed duties as the deputy for Command Center operations. In that, his usual role, he is responsible for the maintenance, operation, and training of watch teams for the NMCC. He qualified to stand in as the DDO in the NMCC about a month ago, in August 2001. The previous afternoon, Winfield asked Leidig to relieve him for a portion of his duty this morning, and Leidig agreed to do so.
Leidig Takes Over as DDO - As arranged, Leidig takes over from Winfield as DDO at 8:30 a.m., allowing Winfield to attend his meeting. Upon arrival at the NMCC, Leidig receives the intelligence and other turn over briefings. After seeing the reports of the plane crashes in New York on television, he will be responsible for convening a significant event conference (see 9:29 a.m.-9:34 a.m. September 11, 2001), which he soon upgrades to an air threat conference (see 9:37 a.m.-9:39 a.m. September 11, 2001). [9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 6/17/2004 pdf file]
Winfield Does Not Resume Duties until Attacks Are Over - Even though it becomes obvious that a coordinated attack is under way when television shows the second plane hitting the World Trade Center at 9:03 a.m. (see 9:03 a.m. September 11, 2001), Winfield apparently remains in his meeting instead of resuming his duties as DDO (see (Shortly After 9:03 a.m.) September 11, 2001). He will only take over from Leidig as DDO after Flight 93 crashes in Pennsylvania, apparently at around 10:30 a.m. (see (10:30 a.m.) September 11, 2001). [9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 6/17/2004] In later interviews for television, Winfield will give the impression that he remained in charge of the NMCC throughout the 9/11 attacks, and make no mention of having allowed a stand-in to take his place during this most critical period of time.

Flight 175 stops transmitting its transponder signal. It is currently flying near the New Jersey-Pennsylvania border. [Guardian, 10/17/2001; Newsday, 9/10/2002; 9/11 Commission, 6/17/2004] However, the transponder is turned off for only about 30 seconds, and then comes back on as a signal that is not designated for any plane on this day. Then, within the space of a minute, it is changed to another new code. But New York Center air traffic computers do not correlate either of these new transponder codes with Flight 175. Consequently, according to an early FAA report, “the secondary radar return (transponder) indicating aircraft speed, altitude, and flight information began to coast and was no longer associated with the primary radar return.” Therefore, while controllers are able “to track the intruder easily… they couldn’t identify it.” However, Dave Bottiglia, the New York Center air traffic controller responsible for Flight 175, is currently trying to locate the already-crashed Flight 11, and therefore supposedly does not notice the transponder code changes on Flight 175 until 8:51 a.m. (see 8:51 a.m.-8:53 a.m. September 11, 2001). [Federal Aviation Administration, 9/17/2001 pdf file; Washington Post, 9/17/2001; 9/11 Commission, 8/26/2004, pp. 21] According to a “Flight Path Study” by the National Transportation Safety Board, the change of Flight 175’s transponder code is the “first indication of deviation from normal routine.” [National Transportation Safety Board, 2/19/2002 pdf file]

Ed Soliday.Ed Soliday. [Source: Ed Soliday]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 pdf file] 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).

CNN is the first major network to show the footage of the crash site. It breaks into a commercial and anchor Carol Lin says, “This just in. You are looking at… obviously a very disturbing live shot there—that is the World Trade Center, and we have unconfirmed reports this morning that a plane has crashed into one of the towers of the World Trade Center.” CNN then switches to Sean Murtagh, the network’s vice president of finance, who says in a live telephone interview, “I just witnessed a plane that appeared to be cruising at a slightly lower than normal altitude over New York City. And it appears to have crashed into—I don’t know which tower it is—but it hit directly in the middle of one of the World Trade Center towers. It was a jet, maybe a two-engine jet, maybe a 737… a large passenger commercial jet… It was teetering back and forth, wing-tip to wing-tip, and it looks like it has crashed into—probably, twenty stories from the top of the World Trade Center—maybe the eightieth to eighty-fifth floor. There is smoke billowing out of the World Trade Center.” [CNN, 9/11/2001; Bamford, 2004, pp. 16-17] Many reports do not come until a few minutes later. For instance, ABC first breaks into regular programming with the story at 8:52 a.m. [ABC News, 9/14/2002] Incredibly, a NORAD timeline presented to the 9/11 Commission in 2003 claims that CNN doesn’t begin its coverage of the attacks until 8:57.

Bill Roy.Bill Roy. [Source: Publicity photo]Apparently, managers at United Airlines’ System Operations Control (SOC) center, just outside Chicago, are unaware of any unfolding emergency until they see CNN reporting the burning World Trade Center (see 8:48 a.m. September 11, 2001). “Within minutes,” the air traffic control coordinator at United Airlines’ headquarters, located next to the SOC, calls an official at the FAA’s Herndon Command Center to confirm that the plane that just hit the WTC was not one of United’s aircraft. The FAA official tells him the plane had been a hijacked American Airlines 757. Soon afterwards, the air traffic control coordinator briefs Bill Roy and Mike Barber—the director and the dispatch manager at United’s SOC—on this information from the FAA. Barber then tries notifying United’s top corporate officials about it. However, he is unable to because the airline’s pager system is not working.

The United Airlines System Operations Control center.The United Airlines System Operations Control center. [Source: United Airlines]Andy Studdert, United Airlines’ chief operating officer, learns that an American Airlines plane has crashed into the World Trade Center and goes to his airline’s operations center to help respond to the incident, but when he gets there he is told that one of his airline’s planes, Flight 175, is missing. Studdert is in a meeting at United Airlines’ headquarters, near Chicago, with Jim Goodwin, the airline’s chairman and CEO; Rono Dutta, the airline’s president; and three or four other individuals. [Wall Street Journal, 10/15/2001; Chicago Tribune, 7/16/2003; 9/11 Commission, 11/20/2003 pdf file] The meeting, in Goodwin’s office, is about union negotiations. [Center for Values-Driven Leadership, 4/23/2012] Meanwhile, personnel in the airline’s System Operations Control (SOC) center have seen the television coverage of the burning North Tower and been informed that the WTC was hit by an American Airlines plane (see (Shortly After 8:48 a.m.) September 11, 2001). Bill Roy, the SOC director, called the adjacent headquarters building and passed on the news to Studdert’s secretary, Maryann Irving.
Managers Are Baffled at the News of the Crash - Irving now runs to Goodwin’s office and, once there, tells Studdert: “Andy, call the SOC. An American plane just went into the World Trade Center.” [Wall Street Journal, 10/15/2001; 9/11 Commission, 11/20/2003 pdf file] The men in the office, Studdert will later recall, say to each other: “That’s nuts. That can’t happen. There’s no way, under any circumstances, that an airline pilot is gonna hit the World Trade Center.” [Center for Values-Driven Leadership, 4/23/2012] Studdert thinks the plane that hit the WTC “couldn’t have been American Airlines, because that wasn’t an ordinary flight route.” [9/11 Commission, 11/20/2003 pdf file] The men in Goodwin’s office switch on a TV and see the coverage of the WTC on fire.
Manager Learns that a United Airlines Flight Is Missing - Studdert immediately goes to respond to the incident. Although the plane that reportedly hit the WTC doesn’t belong to United Airlines, according to Studdert, “there’s a fraternity… of the airlines, so we would help each other during a crisis.” He heads across the complex to the SOC—the operations center. [Center for Values-Driven Leadership, 4/23/2012] The operations center is a room about the size of a football field in which around 300 people are working, tracking planes and pulling up information relating to the airline’s flights. [Longman, 2002, pp. 77] When Studdert arrives there, he says aloud, “Confirm American into the World Trade Center.” [Chicago Tribune, 7/16/2003; Center for Values-Driven Leadership, 4/23/2012] However, someone in the operations center informs him that contact has now been lost with a United Airlines plane, Flight 175. A few minutes later, Studdert is told that a supervisor at the airline’s maintenance office in San Francisco called and said Flight 175 has been reported as hijacked (see Shortly Before 9:00 a.m. September 11, 2001). [Wall Street Journal, 10/15/2001; Chicago Tribune, 7/16/2003; 9/11 Commission, 11/20/2003 pdf file; 9/11 Commission, 8/26/2004, pp. 22]
Manager Tells Employees, 'This Is Not a Drill' - Studdert is concerned that personnel in the operations center might think the apparent crisis is a scenario in a training exercise. [Chicago Tribune, 7/16/2003] This is because 12 days ago he held a surprise exercise in which contact was lost with a United Airlines plane flying over the Pacific Ocean and airline personnel were led to believe the aircraft had crashed (see August 30, 2001). [USA Today, 8/12/2002; Studdert, 5/26/2015 pdf file; Dubuque Telegraph Herald, 11/12/2015] It is possible that personnel in the operations center are indeed confused over whether the current crisis is simulated, as part of another exercise. According to the Chicago Tribune, Studdert senses “disbelief among his employees” and so he tells them, “This is not a drill.” [Chicago Tribune, 7/16/2003] But according to USA Today, “the staff already knows” this is not another exercise. [USA Today, 8/12/2002]
Airline Employees See Second Crash on TV - At 9:03 a.m., Studdert and his colleagues see Flight 175 crashing into the South Tower of the WTC live on television (see 9:03 a.m. September 11, 2001). [Wall Street Journal, 10/15/2001] Studdert, however, is unsure whether this second plane to hit the WTC was a United Airlines flight, because the clarity of the image on television is too poor to tell. [9/11 Commission, 11/20/2003 pdf file] Studdert will be involved in activating his airline’s crisis center in response to the attacks (see (9:00 a.m.) September 11, 2001).

According to the 9/11 Commission, Dave Bottiglia, the air traffic controller handling Flight 175, only notices now that this flight’s transponder signal has changed (see 8:46 a.m.-8:47 a.m. September 11, 2001). Bottiglia asks Flight 175 to return to its proper transponder code. There is no response. Beginning at 8:52 a.m., he makes repeated attempts to contact it, but there is still no response. Bottiglia contacts another controller at 8:53 a.m., and says: “We may have a hijack. We have some problems over here right now.… I can’t get a hold of UAL 175 at all right now and I don’t know where he went to.” [New York Times, 10/16/2001; 9/11 Commission, 6/17/2004; Spencer, 2008, pp. 48] This account apparently conflicts with earlier accounts that claim NORAD’s Northeast Air Defense Sector (NEADS) was notified at 8:43 a.m. that Flight 175 had been hijacked (see 8:43 a.m. September 11, 2001).

The attendant reports that Flight 175 has been hijacked, both of its pilots have been killed, a flight attendant has been stabbed, and the hijackers are probably flying the plane. The line then goes dead. [Wall Street Journal, 10/15/2001; 9/11 Commission, 7/24/2004, pp. 7-8; 9/11 Commission, 8/26/2004, pp. 21] The call, which lasts 75 seconds, is made using an Airfone in row 31 at the back of the plane. Flight crews on United aircraft are able to contact the maintenance office simply by dialing *349 on an Airfone. [9/11 Commission, 8/26/2004, pp. 90-91; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] The identity of the attendant making the call is unclear. According to the Wall Street Journal, the caller is “a female flight attendant.” [Wall Street Journal, 10/15/2001] The 9/11 Commission Report, however, refers to them as “a male flight attendant,” and one of the Commission’s earlier staff statements will specifically name Robert Fangman, who is one of the attendants on Flight 175. [9/11 Commission, 1/27/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 7; 9/11 Commission, 8/26/2004, pp. 18] A summary of the phone calls made from the four hijacked planes presented at the 2006 Zacarias Moussaoui trial will refer to the caller simply as a “flight attendant,” with a question mark signifying their name. [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] After the call ends, Policastro and also another employee at the maintenance office try contacting Flight 175 using ACARS (an e-mail system that enables personnel on the ground to rapidly communicate with those in the cockpit of an aircraft), but they receive no response to these and subsequent attempts at reaching the flight. According to GTE Airfone records, another successful call will be made from Flight 175 to the maintenance office four minutes after this first one (see 8:56 a.m. September 11, 2001). However, other evidence indicates only one call is made. Shortly before 9:00 a.m., a supervisor at the maintenance office will call the United Airlines System Operations Control center, just outside Chicago, and inform a manager there of the reported hijacking of Flight 175 (see Shortly Before 9:00 a.m. September 11, 2001). The supervisor also calls the airline’s security chief. [9/11 Commission, 8/26/2004, pp. 21-22 and 90]

Captain Deborah Loewer. [Source: Military Sealift Command]Navy Captain Deborah Loewer, director of the White House Situation Room, tells President Bush a plane has crashed into the World Trade Center when his limousine arrives at the Emma E. Booker Elementary School in Sarasota, Florida, where he is going to attend a reading demonstration. [Associated Press, 11/26/2001; Dayton Daily News, 8/17/2003] Loewer learned about the crash when Rob Hargis, the senior duty officer in the Situation Room, called her as she was being driven to the school and told her what had happened (see (Between 8:48 a.m. and 8:55 a.m.) September 11, 2001). [McClatchy Newspapers, 8/29/2011; Priess, 2016, pp. 239-240] As soon as the president’s motorcade arrives at the school (see (8:55 a.m.) September 11, 2001), she runs toward Bush’s limousine to pass on the news to the president. [Dayton Daily News, 8/17/2003] She approaches Bush and Andrew Card, his chief of staff, as they are walking toward the school’s entrance. She says to Bush, “Mr. President, the Situation Room is reporting that one of the World Trade Center towers has been hit by a plane.” She adds, “This is all we know.” She also says experience has taught her that first reports are often wrong. Bush replies, “Thank you, Captain” as he continues making his way toward the school’s entrance and then says, “Keep me informed.” Loewer is “the first person to inform President Bush that terrorism had struck New York City,” according to the Associated Press. [Associated Press, 11/26/2001; Springfield News-Sun, 9/9/2011; Bohn, 2015, pp. 214; Priess, 2016, pp. 240] However, some accounts will claim that either Karl Rove, Bush’s senior adviser, or Card is the first person to tell the president a plane has crashed into the WTC (see (Shortly After 8:55 a.m.) September 11, 2001). [Sammon, 2002, pp. 41-42; Rove, 2010, pp. 249-250; Politico Magazine, 9/9/2016] After passing on the news about the crash, Loewer goes to the holding room next to the classroom where Bush is going to listen to some children reading. There, she will learn about Flight 175 crashing into the WTC when the attack occurs, at 9:03 a.m. (see 9:03 a.m. September 11, 2001). [Bohn, 2015, pp. 214; Priess, 2016, pp. 240-241]

According to GTE Airfone records, an attendant on Flight 175 makes a call to the United Airlines maintenance office in San Francisco at this time, but the employee who would have answered it denies this. The call is supposedly made using an Airfone in row 31 at the back of the plane, and lasts 31 seconds. [9/11 Commission, 8/26/2004, pp. 90-91; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] A Flight 175 attendant, possibly Robert Fangman, called the maintenance office four minutes earlier and spoke with employee Marc Policastro (see 8:52 a.m. September 11, 2001). [9/11 Commission, 1/27/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 7] But Policastro, who would have also answered this second call had it occurred, later recalls only one communication from the flight. United Airlines investigators will conclude that only one call is received. According to Airfone records, a third call from Flight 175 to the maintenance office is attempted a minute later, at 8:57, but this fails to connect.

A special radio transmitter that is carried by aircraft and designed to go off automatically if a plane crashes is activated in the New York area, several minutes before Flight 175 hits the World Trade Center. David Bottiglia, an air traffic controller at the FAA’s New York Center, receives information from one of the aircraft he is monitoring. A few seconds before 8:59 a.m., the pilot of US Airways Flight 583 tells him, “I hate to keep burdening you with this stuff, but now we’re picking up another ELT on 21.5.” [Federal Aviation Administration, 9/11/2001, pp. 37 pdf file; 9/11 Commission, 10/1/2003 pdf file; 9/11 Commission, 2004] An “ELT” is an emergency locator transmitter, a device carried on most general aviation aircraft in the US that is designed to automatically begin transmitting a distress signal if a plane should crash, so as to help search and rescue attempts at locating the downed aircraft. [Federal Aviation Administration, 3/23/1990; US Department of the Army, 8/12/2008, pp. E-6 pdf file; Aircraft Owners and Pilots Association, 1/22/2009] “21.5” refers to the emergency frequency of 121.5 megahertz that ELTs transmit their distress signals on. [Aircraft Electronics Association, 2009, pp. 36 pdf file] While the pilot’s information would mean an ELT is activated at around 8:58 a.m., Flight 175 will crash into the WTC several minutes later, at 9:03 a.m. and 11 seconds (see 9:03 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 8] And yet there are no reports of an ELT going off at the time of the crash itself. The pilot of Flight 583 earlier on informed Bottiglia of another ELT signal, which had been transmitted shortly before Flight 11 hit the WTC (see 8:44 a.m. September 11, 2001).

Jim Goodwin.Jim Goodwin. [Source: Chicago Tribune]Rich Miles, the manager at the United Airlines System Operations Control (SOC) center just outside Chicago, receives a call from a supervisor at United’s maintenance office in San Francisco, informing him that Flight 175 has been reported as hijacked. [Wall Street Journal, 10/15/2001; 9/11 Commission, 8/26/2004, pp. 22] The maintenance office received a call minutes earlier from a flight attendant on United 175, who said their plane had been hijacked (see 8:52 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 7-8] When the supervisor tells Miles about this, he initially responds, “No, the information we’re getting is that it was an American 757.” (The FAA has just informed United Airlines that the plane that hit the World Trade Center was a hijacked American Airlines 757 (see (Shortly After 8:48 a.m.) September 11, 2001).) But the supervisor insists, “No, we got a call from a flight attendant on 175.” [Wall Street Journal, 10/15/2001] Miles notifies his boss Bill Roy, the SOC director, about this information. Roy then contacts United’s CEO Jim Goodwin and its chief operating officer Andy Studdert, who are in a meeting at the airline’s headquarters, located next to the SOC. Roy then begins the process of activating the crisis center at the United headquarters, which will take about 30 minutes to complete.

United Airlines activates its crisis center, from where it will respond to the terrorist attacks. [9/11 Commission, 11/20/2003 pdf file; 9/11 Commission, 8/26/2004, pp. 22] Personnel at United Airlines’ System Operations Control (SOC) center, near Chicago, learned that a plane had crashed into the World Trade Center when they saw the television coverage of the incident. Minutes later, they were informed that the WTC was hit by a hijacked American Airlines plane (see (Shortly After 8:48 a.m.) September 11, 2001). Shortly before 9:00 a.m., a supervisor at the airline’s maintenance office in San Francisco, California, called the SOC—the operations center—and said a United Airlines plane, Flight 175, had been reported as hijacked (see Shortly Before 9:00 a.m. September 11, 2001). [Wall Street Journal, 10/15/2001; 9/11 Commission, 8/26/2004, pp. 21-22] United Airlines’ usual procedure when there is a crisis involving one of its aircraft is to isolate that aircraft and move the handling of it to the crisis center, so as not to disrupt operations in the rest of the system.
Crisis Center Is Activated in about 30 Minutes - The crisis center, which is located just off the operations center, is apparently activated sometime around 9:00 a.m. It takes about 30 minutes for staffers to assemble and fully activate it. When the center is activated, a representative from every division of the airline’s corporate structure has to report to it, and once they arrive they have predetermined duties they are required to carry out. Clipboards are therefore distributed to operations center staffers, which show a list of people who are needed in the crisis center that they have to call. A phone bridge is set up with the airline’s other crisis centers, which are activated around this time in San Francisco and Denver, Colorado. [9/11 Commission, 11/20/2003 pdf file; 9/11 Commission, 11/21/2003 pdf file; 9/11 Commission, 8/26/2004, pp. 22] Patti Carson, United Airlines’ vice president of human resources, will later recall that after they see the live television coverage of Flight 175 crashing into the WTC at 9:03 a.m. on a screen in the operations center (see 9:03 a.m. September 11, 2001), “Without exchanging a word, every crisis team member in the room walked the 10 or 15 steps to the airline’s crisis center and took their positions.” [HR (.com), 7/1/2005]
Opening the Center Is 'the Single Most Significant Thing You Do' - The crisis center is “a terraced, theater-like room that resembled NASA’s Mission Control,” according to journalist and author Jere Longman. On one wall is a large screen on which United Airlines’ flights are displayed. [Longman, 2002, pp. 77; USA Today, 8/12/2002] Other screens in the center show CNN and other TV news channels. [9/11 Commission, 11/20/2003 pdf file] Opening the crisis center, according to Andy Studdert, United Airlines’ chief operating officer, “is the single most significant thing you do [at an airline], because once that happens… everybody in an airline has a second job and that second job is to either run the airline… or act to support the crisis.” Once the center has been opened, “3,000 people are put on an immediate activation,” Studdert will say. [Center for Values-Driven Leadership, 4/23/2012]
Different People Later Claim to Have Activated the Center - It is unclear when exactly the crisis center is activated and who activates it. Bill Roy, the SOC director, will say he is responsible for activating the center and he does this shortly after he learned a plane had crashed into the WTC. This is presumably sometime around 8:50 a.m. or shortly after. Roy will say that by around 9:00 a.m., he and his colleagues are in the process of activating the center. [9/11 Commission, 11/20/2003 pdf file; 9/11 Commission, 1/27/2004] But Rich Miles, the SOC manager, will indicate that he activates the center and he does this apparently at around 9:00 a.m. He will say that after they saw the television coverage of the burning WTC and then learned that the North Tower was hit by an American Airlines plane, staffers in the operations center discussed what to do and considered whether to open the crisis center. One member of staff went into the center, and started turning on computers and other equipment. Miles will recall that after the supervisor at the airline’s maintenance office in San Francisco called, shortly before 9:00 a.m., with the news that Flight 175 had been reported as hijacked, he begins activating the center. [9/11 Commission, 11/21/2003 pdf file; 9/11 Commission, 8/26/2004, pp. 21-22]
COO Is Authorized to Activate the Crisis Center - Other accounts will suggest that Studdert is responsible for activating the crisis center. Studdert will recall that sometime after 9:00 a.m., when he arrived at the operations center (see (8:50 a.m.-9:03 a.m.) September 11, 2001), he realizes that the airline is “in a crisis, and we immediately activate the crisis center.” [9/11 Commission, 1/27/2004; Center for Values-Driven Leadership, 4/23/2012] Furthermore, Ed Soliday, United Airlines’ vice president of safety and security, will indicate that Studdert is one of only a few people with authority to activate the crisis center. He will say that although the airline’s usual protocol is to obtain a “vote of three” before opening the center, both Studdert and he are empowered to order it activated on their own say-so. Since Soliday will arrive at United Airlines’ headquarters at around 9:35 a.m., this would suggest that only Studdert could order that the crisis center be activated on his own at the current time. [9/11 Commission, 11/21/2003 pdf file]
Center Remains Operational for Three Weeks - The crisis center will remain in operation around the clock every day for the next three weeks. It will provide United Airlines personnel around the country with instant access to resource providers and key decision makers. [9/11 Commission, 1/27/2004] The center was previously activated just 12 days ago, when Studdert ran a surprise “no-notice” exercise in which United Airlines personnel were led to believe that one of their planes had crashed (see August 30, 2001).

Ed Ballinger.Ed Ballinger. [Source: CNN]At the United Airlines System Operations Control (SOC) center outside Chicago, flight dispatcher Ed Ballinger learns that Flight 175 is suspected as being hijacked, and then sends text messages to try and make contact with it. [9/11 Commission, 8/26/2004, pp. 23-24] The SOC center has just been contacted by the United Airlines maintenance office in San Francisco, about a call it received from an attendant on Flight 175, who had reported that their plane had been hijacked (see Shortly Before 9:00 a.m. September 11, 2001). [Wall Street Journal, 10/15/2001] Subsequently, around 9:01 or 9:02, a dispatch manager at the SOC goes to Ballinger’s desk and informs him of the details of this call. [9/11 Commission, 8/26/2004, pp. 23] Ballinger is the flight dispatcher responsible for United’s aircraft flying from the East Coast to the West Coast, which include Flight 175 (and also Flight 93). [Chicago Daily Herald, 4/14/2004] At 9:03, he sends an ACARS message to Flight 175: “How is the ride. Anything dispatch can do for you.” (ACARS is an e-mail system that enables personnel on the ground to rapidly communicate with those in the cockpit of an aircraft.) At the same time, the United Airlines air traffic control coordinator also sends an ACARS message to the flight: “NY approach lookin for ya on [frequency] 127.4.” Just after 9:03, unaware it has now crashed into the World Trade Center, Ballinger and the air traffic control coordinator re-send these ACARS messages to Flight 175. [9/11 Commission, 8/26/2004, pp. 9 and 23-24] Twenty minutes later, Ballinger will remain unaware that Flight 175 has crashed and still be trying to contact it by ACARS (see 9:23 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 26] All airlines have a staff of dispatchers like Ballinger who, under FAA rules, are responsible for monitoring aircraft in flight. They follow each flight’s progress, relay safety information, and handle any problems that arise. [Spencer, 2008, pp. 14 and 35] United Airlines dispatchers typically monitor up to two dozen flights at once. [Longman, 2002, pp. 68] Ballinger has 16 transcontinental flights taking off early this morning that he is responsible for. [New York Observer, 6/20/2004]

An announcement is made over the public address system in the South Tower of the World Trade Center, advising workers that they can begin an orderly evacuation of the building if conditions warrant it. [New York Times, 5/17/2004; 9/11 Commission, 7/24/2004, pp. 289] A previous announcement over the public address system instructed people in the South Tower 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. 287-288; Dwyer and Flynn, 2005, pp. 72] The new announcement begins: “May I have your attention, please. Repeating this message: the situation occurred in Building 1 [i.e. the North Tower].” The announcer then says, “If the conditions warrant on your floor, you may wish to start an orderly evacuation.” [New York Times, 5/17/2004] The announcement is presumably made by Philip Hayes, the deputy fire safety director on duty at the fire command desk in the lobby of the South Tower. A button at the desk enables fire safety directors to deliver announcements over the public address system. [Dwyer and Flynn, 2005, pp. 26]
Identity of Person Who Ordered Evacuation Unclear - The new advice, for tenants to evacuate, does “not correspond to any prewritten emergency instruction,” according to the 9/11 Commission Report. [9/11 Commission, 7/24/2004, pp. 289] It is unclear who told Hayes to make the announcement giving this advice. George Tabeek, the Port Authority’s security manager for the WTC, contacted the fire command desks in the Twin Towers immediately after Flight 11 hit the North Tower, with instructions about what to do. His orders for Hayes, however, were to “keep people inside the South Tower” (see Shortly After 8:46 a.m. September 11, 2001). [New Jersey Star-Ledger, 9/6/2011]
Police Commander Called for Evacuation of WTC - Captain Anthony Whitaker, the Port Authority Police Department (PAPD) commanding officer at the WTC, called for the evacuation of the WTC at 9:00 a.m. (see 8:59 a.m.-9:02 a.m. September 11, 2001). However, his instruction was given over PAPD radio channel W, “which could not be heard by the deputy fire safety director in the South Tower,” according to the 9/11 Commission Report. [Murphy, 2002, pp. 184-185; 9/11 Commission, 7/24/2004, pp. 293; National Institute of Standards and Technology, 9/2005, pp. 201] Furthermore, according to the Port Authority, deputy fire safety directors do not generally take direct orders from the PAPD under the regular chain of command. Therefore, the 9/11 Commission Report will state, it is “not known if [Hayes] received the order by the PAPD to evacuate the complex.” [9/11 Commission, 7/24/2004, pp. 544]
Fire Department Responsible for Ordering Evacuations - According to New York Times reporters Jim Dwyer and Kevin Flynn, “The authority to order an evacuation during a fire normally rests with the fire department.” [Dwyer and Flynn, 2005, pp. 79] In a phone call with his counterpart in the North Tower, at 8:49 a.m., Hayes in fact said he would wait to hear from “the boss from the fire department or somebody” before ordering an evacuation of the South Tower (see 8:49 a.m. September 11, 2001). [Port Authority of New York and New Jersey, 9/11/2001 pdf file; 9/11 Commission, 7/24/2004, pp. 287; Dwyer and Flynn, 2005, pp. 27] But whether someone from the fire department told Hayes to order an evacuation is unknown. It is also unclear how long announcements, advising an evacuation, continue for. Hayes and his counterpart in the North Tower are “making announcements that the situation was serious and that occupants should evacuate immediately” for “[a]s long as the [fire alarm system] was still operational,” according to Fire Engineering magazine. [Fire Engineering, 11/1/2002] However, the 9/11 Commission Report will state, “Evidence suggests that the public address system [in the South Tower] did not continue to function after the building was hit.” This would mean no announcements go out after 9:03 a.m., when Flight 175 hits the tower (see 9:03 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 295] By the time the South Tower collapses (see 9:59 a.m. September 11, 2001), out of around 8,540 people who were originally in the building, 7,940 (93 percent) have made it out and will survive, according to the National Institute of Standards and Technology.

Flight 175 hits the WTC South Tower. The picture was taken from a traffic helicopter.Flight 175 hits the WTC South Tower. The picture was taken from a traffic helicopter. [Source: WABC 7/ Salient Stills]Flight 175 hits the South Tower of the World Trade Center (Tower Two). Seismic records pinpoint the time at six seconds before 9:03 a.m. (rounded to 9:03 a.m.). Hijackers Marwan Alshehhi, Fayez Ahmed Banihammad, Mohand Alshehri, Hamza Alghamdi, and Ahmed Alghamdi presumably are killed instantly, and many more in the tower will die over the next few hours. [New York Times, 9/12/2001; CNN, 9/12/2001; CNN, 9/17/2001; North American Aerospace Defense Command, 9/18/2001; USA Today, 12/20/2001; Federal Emergency Management Agency, 5/1/2002, pp. 1-10; New York Times, 5/26/2002; Associated Press, 8/21/2002; USA Today, 9/2/2002] According to the NIST report, the crash time is 9:02:59. [National Institute of Standards and Technology, 9/2005, pp. 38] According to the 9/11 Commission Report, the crash time is 9:03:11. [9/11 Commission, 7/24/2004, pp. 8] Millions watch the crash live on television. The plane strikes the 77th through 85th floors in the 110-story building. Approximately 100 people are killed or injured in the initial impact; 600 people in the tower eventually die. The death toll is far lower than in the North Tower because about two-thirds of the South Tower’s occupants have evacuated the building in the 17 minutes since the first tower was struck. [USA Today, 12/20/2001; National Institute of Standards and Technology, 9/2005, pp. 5-9, 41] The combined death toll from the two towers is estimated at 2,819, not including the hijackers. [Associated Press, 8/21/2002] The impact severs some columns on the south side of the South Tower. Each of the Twin Towers is designed as a “tube-in-tube” structure and the steel columns which support its weight are arranged around the perimeter and in the core. The plane, which is traveling at an estimated speed of around 500 mph (see October 2002-October 2005), severs 33 of the building’s 236 perimeter columns and damages another one. [National Institute of Standards and Technology, 9/2005, pp. 39] The perimeter columns bear about half of the tower’s weight, so the damage to them reduces the tower’s ability to bear gravity loads by about 7.1 percent. [National Institute of Standards and Technology, 9/2005, pp. 6] The actual damage to the 47 core columns is not known, as there are no photographs or videos of it, but there will be much speculation about this after 9/11. It will be suggested that some parts of the aircraft may be able to damage the core even after crashing through the exterior wall (see 8:46 a.m. September 11, 2001). [National Institute of Standards and Technology, 9/2005, pp. 107] According to NIST’s base case model, five of the core columns are severed and another five suffer some damage. [National Institute of Standards & Technology, 9/2005, pp. 235 pdf file] This may reduce the tower’s ability to bear loads by a further approximately 8 percent, meaning that the aircraft impact accounted for a loss of about 15 percent of the building’s strength. This damage will be cited as an event contributing to the building’s collapse after 9/11 (see October 23, 2002 and October 19, 2004). NIST’s base case estimate of damage to the North Tower’s core will be similar, even though the aircraft impact there was dissimilar (see 8:46 a.m. September 11, 2001). Flight 11 hit the North Tower’s core head on, whereas Flight 175 only hits the corner of the South Tower’s core. [National Institute of Standards and Technology, 9/2005, pp. 20-23, 38-41] In addition, some of the fireproofing on the steel columns and trusses may be dislodged (see 8:46 a.m. September 11, 2001). [National Institute of Standards & Technology, 9/2005, pp. xxxvi, 83 pdf file] Photographs and videos of the towers will not show the state of fireproofing inside the buildings, but the National Institute of Standards and Technology (NIST) will try to estimate the damage to fireproofing using a series of computer models. Its severe case model (see (October 2002-October 2005)) will predict that 39 of the 47 core columns are stripped of their fireproofing on one or more floors and that fireproofing is stripped from trusses covering 80,000 ft2 of floor area, the equivalent of about two floors. NIST will say that the loss of fireproofing is a major cause of the collapse (see April 5, 2005), but only performs 15 tests on fireproofing samples (see October 26, 2005). [National Institute of Standards and Technology, 9/2005, pp. 41] According to NIST, less fireproofing is stripped from the North Tower (see 8:46 a.m. September 11, 2001).

Denny Watson.Denny Watson. [Source: Risk Assessment Network + Exchange]Secretary of Defense Donald Rumsfeld goes ahead with his daily intelligence briefing in his office at the Pentagon, even though Denny Watson, his CIA briefer, urges him to cancel it and respond to the terrorist attacks. [Rumsfeld, 2011, pp. 335; Priess, 2016, pp. 244] Rumsfeld has just been in a meeting in his private dining room that was attended by several members of Congress (see (8:00 a.m.-8:50 a.m.) September 11, 2001). During it, he was informed that a plane had crashed into the World Trade Center (see Shortly After 8:46 a.m. September 11, 2001). [Associated Press, 9/12/2001; US Department of Defense, 12/5/2001; 9/11 Commission, 3/23/2004] He assumed the crash was an accident. [Vogel, 2007, pp. 428; Rumsfeld, 2011, pp. 335]
Rumsfeld Went to His Office for His Intelligence Briefing - After the meeting ended, apparently around 9:00 a.m., he returned to his office to receive his intelligence briefing. [Historical Office, Office of the Secretary of Defense, 7/18/2002 pdf file; 9/11 Commission, 7/24/2004, pp. 37] Rumsfeld receives an intelligence briefing from Watson each morning, similar to the intelligence briefing provided to the president each day. The briefings usually last at least half an hour. [Rumsfeld, 2011, pp. 335; Priess, 2016, pp. 243] The briefing today is scheduled to run from 9:00 a.m. to 9:30 a.m. [US Department of Defense, 8/12/2002]
CIA Briefer Learned of the Crashes from TV - Watson, meanwhile, recently arrived at the Pentagon and learned about the crashes at the WTC. After she entered the building, she noticed people staring at a television, which showed the North Tower burning after being hit by a plane. She then went to the anteroom of Rumsfeld’s office, where she saw the second hijacked plane crashing into the WTC live on television (see 9:03 a.m. September 11, 2001). She immediately called the operations center at CIA headquarters to see if she could find out more about what was happening. She was told only that there were 50 planes still airborne that were unaccounted for.
Rumsfeld Refuses to Cancel the Briefing - Rumsfeld then calls Watson into his office. Assuming the briefing will be suspended due to what has happened in New York, the CIA analyst hasn’t even opened her briefcase to pull out her copy of the President’s Daily Brief (PDB). “Sir, you just need to cancel this,” she says to Rumsfeld as she enters the office. “You’ve got more important things to do,” she adds. Rumsfeld, however, wants to go ahead with the briefing. “No, no, we’re going to do this,” he says. Watson then sits down and tells Rumsfeld what she learned from the CIA’s operations center, but the secretary of defense simply nods his head and starts flipping through the PDB. [Priess, 2016, pp. 244] The PDB apparently contains no remarkable information today. “As we reviewed the threat reports from around the world, September 11 seemed to be no more or less different than any other day,” Rumsfeld will later comment. [Rumsfeld, 2011, pp. 336]
Rumsfeld Will Be Receiving the Briefing When the Pentagon Is Hit - Vice Admiral Edmund Giambastiani Jr., Rumsfeld’s senior military assistant, will come into the office around this time and tell the secretary of defense about the second crash at the WTC (see (Shortly After 9:03 a.m.) September 11, 2001). [Historical Office, Office of the Secretary of Defense, 7/18/2002 pdf file; US Department of Defense, 8/12/2002] Two of Rumsfeld’s aides will also come to the office and, like Watson, try, unsuccessfully, to persuade Rumsfeld to cancel his schedule so he can respond to the attacks (see a904rumsfeldrefuses). [Clarke, 2006, pp. 218-219; Priess, 2016, pp. 244] Rumsfeld will be in his office with Watson, still receiving his intelligence briefing, at 9:37 a.m., when the Pentagon is attacked (see 9:37 a.m. September 11, 2001).

Earlier this morning, many White House staffers were busy preparing for the annual Congressional picnic, which was scheduled to take place this evening (see 8:30 a.m. September 11, 2001). About 170 to 180 picnic tables have been set up on the South Lawn for the event. After he learns that a second plane has crashed into the World Trade Center (see 9:03 a.m. September 11, 2001), Walters decides to start moving the picnic tables off the lawn so Bush’s helicopter will be able to land on the grounds when the president returns to the White House. [National Journal, 8/31/2002; Values in World Thought, 4/4/2006; Peter Schnall, 7/12/2016]
Usher Arranges to Clear the Lawn - He coordinates with the National Park Service, which is in charge of the White House grounds, to determine who will be clearing away the picnic tables. [Brower, 2015, pp. 257] He then sets about moving the tables. “I got the staff together and started sending them out to the south grounds—anybody I could think of—because I knew that we had to try to move as quickly as possible,” he will later recall. [National Journal, 8/31/2002] However, at about 9:45 a.m., the White House is evacuated after the Secret Service learns of a possible threat against it (see (9:45 a.m.) September 11, 2001). [Associated Press, 2001 pdf file; CNN, 9/12/2001]
Staffers Continue Clearing the Grounds, despite the Danger - Around this time, Walters sees the smoke coming from the Pentagon, which was attacked at 9:37 a.m. (see 9:37 a.m. September 11, 2001), and realizes the White House could be hit next. And yet he decides that he needs to stay where he is in order to clear up the grounds. “As far as I was concerned, my responsibility was there at the White House,” he will comment. [Brower, 2015, pp. 258] “I knew we had to get those tables out,” he will state, adding, “I even felt more urgency, since obviously this was a coordinated attack now.” [National Journal, 8/31/2002] While the Secret Service is ordering people to run for their lives, Walters grabs a few of his colleagues and tells them they need to stay and help clear away the picnic tables. “I got the word that everybody was evacuating, but we had something that we needed to do,” he will comment. [Brower, 2015, pp. 258] After hearing that another suspicious plane is approaching, however, Walters and his colleagues go to the southeast knoll, a rise in the White House lawn, and just stand there, watching the sky and waiting.
Lawn Is Cleared by Early Afternoon - By around 11:00 a.m., they are becoming impatient. Walters therefore says, “Guys, let’s go move some picnic tables.” The men then start carrying the picnic tables off the lawn. A police officer joins them and eventually about a dozen people are helping them to move the tables. By around 1:00 p.m. all of the tables have been removed from the lawn. At about 3:45 p.m., Walters is called by someone from the military, who asks him to clear the South Lawn so the president’s helicopter will be able to land there. Walters laughs and says this has already been done. [National Journal, 8/31/2002] The president’s helicopter, with Bush on board, will land on the South Lawn at around 6:55 p.m. (see (6:54 p.m.) September 11, 2001). [CNN, 9/12/2001; Rove, 2010, pp. 263]
Usher Will Later Justify His Actions - Walters will, in 2016, explain why he made the effort to clear up the White House grounds, despite the danger to himself and his colleagues. “One of the things that I turned to in my own mind on 9/11 was the role that the White House plays in disasters, wars,” he will say, adding, “People have a tendency to turn to the White House.” He will continue: “And I knew that the president wasn’t gonna be satisfied talking from a bunker somewhere or away from the White House. And that’s why we put the effort that we did into cleaning up the south grounds, so that [his] helicopter could land there. That was what the American people were used to seeing—the presidential helicopter coming in—and the president was going to address the nation from the Oval Office.” [Peter Schnall, 7/12/2016]

Laura Bush, the president’s wife, leaves the White House in her limousine, on her way to Capitol Hill where she is scheduled to testify before a Congressional committee, but she is unaware that a second plane has crashed into the World Trade Center. [Us Weekly, 10/15/2001; National Journal, 8/31/2002; Bush, 2010, pp. 198] Bush is set to appear before the Senate Committee on Health, Education, Labor, and Pensions, where she will talk about early childhood education. [CNN, 9/12/2001; CNN, 9/11/2002] She was informed of the first crash at the WTC by her lead Secret Service agent as she was getting into her limousine (see (8:55 a.m.) September 11, 2001).
First Lady Unaware of Second Crash - The limousine leaves the White House at 9:07 a.m., according to Noelia Rodriguez, the first lady’s press secretary. [National Journal, 8/31/2002] The second aircraft, Flight 175, hit the WTC four minutes earlier (see 9:03 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 8] However, Bush and those with her in the limousine are unaware of this. [Bush, 2010, pp. 197-198]
First Lady Thinks about Canceling Hearing - Nevertheless, Bush already thinks the Senate hearing she is on her way to should perhaps be canceled, because New York Senator Hillary Clinton is on the education committee and is therefore supposed to attend. Bush will comment, “Even after the first [crash], when I thought it was just an accident, I thought we probably should cancel, because Mrs. Clinton was on the committee and she’s from New York, and she’d probably want to rush home at that time.” [USA Today, 9/10/2001; Gerhart, 2004, pp. 162] All the same, Bush continues with the two-mile journey from the White House to Capitol Hill. She will learn of the second crash, and realize this is a terrorist attack, shortly before arriving at the Russell Senate Office Building, where the hearing is set to take place (see (9:14 a.m.) September 11, 2001).
Secret Service Allows Bush to Head to Event - Members of Bush’s Secret Service detail apparently raise no objection to Bush going ahead with her trip to Capitol Hill. [CNN, 9/11/2002; Gerhart, 2004, pp. 162; Bush, 2010, pp. 198] The Secret Service is responsible for protecting the first lady, and she is considered to be one of the nation’s “most visible targets.” [US Department of the Treasury, 5/8/2001; Office of Management and Budget, 7/2001, pp. 82 pdf file] The agency’s mission includes keeping her “in sight and out of harm’s way,” according to a book about the Secret Service by author Philip Melanson. [Melanson, 2002, pp. 273] And, as one of the Secret Service’s “permanent protectees,” the first lady, like the president, has a detail of special agents assigned to her. [United States Secret Service, 2002] Bush currently travels with four Secret Service agents and two Secret Service cars. [Kessler, 2006, pp. 136; Kessler, 2009, pp. 181] However, the Secret Service will only take her away from Capitol Hill to a “secure location”—actually the agency’s headquarters—after the terrorist attacks have ended (see (10:10 a.m.-10:55 a.m.) September 11, 2001).

Terry Biggio, the operations manager at the FAA’s Boston Center, instructs the air traffic controllers at his center to contact all aircraft in the center’s airspace by radio and inform them of the events taking place in New York. He tells the controllers to also advise the aircraft to heighten their cockpit security in light of these events. [9/11 Commission, 7/24/2004, pp. 23; 9/11 Commission, 8/26/2004, pp. 25] According to author Lynn Spencer, previously “No transmission of that kind has ever been made on air traffic control frequencies.” Controller Jim Ekins is the first to act. He announces over all the radio frequencies in the sector: “All aircraft! Due to recent events that have unfolded in the Boston sector, you are advised to increase cockpit security. Allow no entry to your cockpit!” According to Spencer, other controllers nearby overhear and realize: “Yes! That’s exactly what we need to tell them!” [Spencer, 2008, pp. 98] The Boston Center air traffic controllers then immediately execute Biggio’s order, and give the warning to their aircraft. [9/11 Commission, 8/26/2004, pp. 25] However, Spencer will write: “Communications with controllers are [usually] as dry as they come, and to many pilots this announcement is so out of their realm of understanding, training, and experience that it simply doesn’t make sense. It actually agitates some, who cannot help but view it as some new kind of ‘FAA bureaucratic bullsh_t.’” [Spencer, 2008, pp. 99] Boston Center will subsequently ask the FAA’s Herndon Command Center to issue a similar cockpit security alert nationwide, but the Command Center apparently will not act on this request (see (9:15 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 23] United Airlines will issue a company-wide order at 9:21 for its dispatchers to warn their flights to secure their cockpits (see 9:21 a.m. September 11, 2001).

Craig Parfitt.Craig Parfitt. [Source: Publicity photo]The United Airlines dispatch operations manager speaks with the American Airlines dispatch operations manager, and they discuss the two plane crashes in New York. [9/11 Commission, 8/26/2004, pp. 25] Mike Barber, the United dispatch manager, is at the airline’s System Operations Control (SOC) center, just outside Chicago, while Craig Parfitt, the American dispatch manager, is at that airline’s SOC center in Fort Worth, Texas. [Wall Street Journal, 10/15/2001] At 9:10, United Airlines is aware a second aircraft has hit the World Trade Center, but it does not realize this is one of its own flights. During their call, Parfitt says to Barber he believes both the aircraft that hit the WTC belonged to American Airlines. (At 9:08 a.m., officials at American Airlines’ SOC mistakenly concluded the second aircraft to hit the WTC might have been Flight 77 (see 9:08 a.m. September 11, 2001).) But Barber says he is increasingly “confident” that the second plane was United Airlines Flight 175. “In slow motion and enlarged images of the second impact on CNN, he could see that the airplane did not have the shiny metallic color of American jets.” By 9:20, according to the 9/11 Commission, although Barber believes the second crashed plane was Flight 175, the identity of this aircraft is “still unconfirmed.” [9/11 Commission, 8/26/2004, pp. 25-26]

The jet fuel that spilled from Flight 175 when it hit the South Tower (see 9:03 a.m. September 11, 2001) has mostly burned up by this time. The National Institute of Standards and Technology (NIST), which later investigates the collapses, will say the “initial jet fuel fires themselves lasted at most a few minutes.” [National Institute of Standards and Technology, 9/2005, pp. 183] Engineering professor Forman Williams will say the jet fuel “burned for maybe 10 minutes.” [Popular Mechanics, 3/2005] Flight 175, a Boeing 767, had a capacity of 23,980 gallons, but was only carrying about 9,100 gallons of fuel when it hit the WTC. NIST will estimate that less than 1,500 gallons were consumed in a fireball inside the tower and 910 to 2,275 gallons were consumed in the fireballs outside the building. Approximately 6,100 gallons therefore splashed onto the office furnishings and started fires on various floors. However, after the jet fuel is used up, office fires burn until the building collapses. NIST will calculate that there were about four pounds per square foot of combustibles in the office space, or about 60 tons per floor. Offices in the WTC actually had fewer combustibles than other similar spaces due to the small number of interior walls and limited bookshelf space. NIST will later find that only three of sixteen perimeter columns it recovers reached a temperature of 250°C and neither of the two core columns it retrieves reached this temperature. NIST will also find that none of the samples it acquires reached a temperature above 600°C (see August 27, 2003). While steel does not melt until its temperature is about 1,600°C, it may begin to lose significant strength at over 500°C. [National Institute of Standards and Technology, 9/2005, pp. 29, 38, 42, 77] The jet fuel also burned up in the North Tower about 10 minutes after it was hit (see 8:57 a.m. September 11, 2001). When a group of firefighters reach the bottom impact floor in the South Tower just before collapse, they only find two isolated fires (see 9:52 a.m. September 11, 2001).

Noelia Rodríguez.Noelia Rodríguez. [Source: Harvard University]Laura Bush, the president’s wife, is told that a second plane has crashed into the World Trade Center and realizes this is a terrorist attack while she is being driven from the White House to Capitol Hill, where she is scheduled to testify before a Congressional committee. [Us Weekly, 10/15/2001; CNN, 9/11/2002; Bush, 2010, pp. 197-198] Bush is set to appear before the Senate Committee on Health, Education, Labor, and Pensions at 10:00 a.m., where she will talk about early childhood education. [USA Today, 9/10/2001; CNN, 9/12/2001; CNN, 9/11/2002] Her lead Secret Service agent informed her of the first crash at the WTC as she was getting into her limousine, outside the White House, but she’d thought the crash was an accident (see (8:55 a.m.) September 11, 2001). [National Journal, 8/31/2002; Gerhart, 2004, pp. 162]
First Lady Told of Second Crash, Knows It Is Terrorism - The Secret Service agents traveling with Bush now tell the first lady about the second crash at the WTC while her limousine is driving up Pennsylvania Avenue, approaching Capitol Hill. “The car fell silent; we sat in mute disbelief,” Bush will later recall. “One plane might be a strange accident; two planes were clearly an attack.” She will note, “We knew then that it was terrorism.” [CNN, 9/11/2002; Bush, 2010, pp. 198]
Members of First Lady's Staff Learn of Crash - Members of Bush’s staff also learn about the second crash around this time, while they are on their way to Capitol Hill. Ashleigh Adams, the first lady’s deputy press secretary, learns of it while traveling in the press van. “It must have been only a couple of minutes after we departed the White House,” Adams will recall, “that the reporters’ and photographers’ pagers and cell phones started to go off, and someone shouted to me, ‘Ashleigh, the second Twin Tower was hit.’” Adams calls Noelia Rodriguez, the first lady’s press secretary, who is traveling in the staff van, and tells her the news. After Rodriguez arrives on Capitol Hill, she will jump out of the staff van, run to Bush’s limousine, and get inside. But she will find that the first lady has already been informed of the second crash. [National Journal, 8/31/2002]
First Lady Learns of Crash 11 Minutes after It Occurs - Bush will recall that she arrives at the Russell Senate Office Building, where the hearing she is set to attend is supposed to take place, two minutes after she is told about the second crash, at 9:16 a.m., meaning she learns of the crash at 9:14 a.m. [Bush, 2010, pp. 198] This is 11 minutes after the second plane, Flight 175, hit the WTC (see 9:03 a.m. September 11, 2001).

Frank Brogan.Frank Brogan. [Source: Publicity photo]The Secret Service allows President Bush to stay at the Emma E. Booker Elementary School in Sarasota, Florida, after a reading demonstration he was participating in has ended, even though he could be in danger at the school. [St. Petersburg Times, 7/4/2004; Politico Magazine, 9/9/2016] Bush has just left the classroom where the reading demonstration was held and entered a holding room next to it. There, he talks on the phone with officials in Washington, DC, and works on a statement to the nation that he wants to deliver before leaving the school (see (9:16 a.m.-9:29 a.m.) September 11, 2001). Members of his staff in the holding room apparently have little information about the terrorist attacks beyond what has been reported on television. They are in contact with the White House Situation Room but not the Pentagon and, according to the 9/11 Commission Report, “No one in the traveling party had any information during this time that other aircraft were hijacked or missing.” [Washington Times, 10/7/2002; 9/11 Commission, 7/24/2004, pp. 38-39] All the same, Secret Service agents and other personnel with the president are concerned that Bush could be in danger at the school, and some of them are worried that terrorists might attack the place (see (9:04 a.m.-9:33 a.m.) September 11, 2001). [Studies in Intelligence, 9/2006 pdf file; Politico Magazine, 9/9/2016]
Bush's Lead Agent Wants to Evacuate the President - Edward Marinzel, the head of Bush’s Secret Service detail, is “eager to get the president out of the school, to Air Force One, and airborne,” according to Karl Rove, Bush’s senior adviser. [Rove, 2010, pp. 251] He therefore approaches Bush and tells him, “We need to get you to Air Force One and get you airborne.” [Politico Magazine, 9/9/2016] However, his concern does not result in Bush being evacuated from the school right away. The Secret Service will later tell the 9/11 Commission that although its agents “were anxious to move the president to a safer location” while he was in the holding room, they “did not think it imperative for him to run out the door.” [9/11 Commission, 7/24/2004, pp. 39]
Chief of Staff Wants Bush to Give His Speech before Leaving - Andrew Card, Bush’s chief of staff, suggests that Bush should be allowed to give his speech to the nation from the school before leaving. He says that “we have a whole auditorium full, waiting for the next event”—meaning Bush’s speech—and there is “no imminent threat there in Sarasota,” according to Dave Wilkinson, assistant special agent in charge of the presidential protection division. The Secret Service therefore accepts a compromise and agrees that Bush can give his speech before leaving. [Politico Magazine, 9/9/2016]
Bush Should Be Taken to the 'Closest Secure Location' - Author Philip Melanson, an expert on the Secret Service, will criticize Bush’s Secret Service detail for failing to get the president away from the school immediately after the second hijacked plane crashed into the World Trade Center, at 9:03 a.m. (see 9:03 a.m. September 11, 2001). “With an unfolding terrorist attack, the procedure should have been to get the president to the closest secure location as quickly as possible, which clearly is not a school,” he will state. [St. Petersburg Times, 7/4/2004] Bush himself will comment on the situation while he is in the holding room, saying, “One thing for certain: I needed to get out of where I was.” [Sammon, 2002, pp. 93]
Bush Refuses to Leave - And yet the president refuses to leave the school at this time when he is urged to do so, according to Frank Brogan, lieutenant governor of Florida, who is in the holding room with him. “The Secret Service tried to get the president to return to Air Force One immediately,” Brogan will state, “but he refused, saying he was committed to staying on the ground long enough to write a statement about what was happening, read it to the nation, and lead a moment of silence for the victims.” [University Press, 9/18/2003] Bush “was courageously insistent about remaining on the ground to make a statement to the people of America,” Brogan will comment. [South Florida Sun-Sentinel, 9/11/2011] Bush will give his speech to the nation, which will be broadcast live on television, from the school library at 9:30 a.m. (see 9:30 a.m. September 11, 2001). [White House, 9/11/2001; Bohn, 2015, pp. 215] He will finally leave the school at around 9:35 a.m. (see (9:34 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 39]

[Gilbert et al., 2002, pp. 64; 9/11 Commission, 7/24/2004, pp. 8; Bush, 2010, pp. 198] At 9:16 a.m., Bush arrived at the Russell Senate Office Building, located just north of the Capitol building, where she was scheduled to testify before a Senate committee at 10:00 a.m. [USA Today, 9/10/2001; CNN, 9/12/2001; Bush, 2010, pp. 198]

[US Department of the Treasury, 5/8/2001; Office of Management and Budget, 7/2001, pp. 82 pdf file; United States Secret Service, 2002] And yet, even though Bush has arrived on Capitol Hill, and over 10 minutes have passed since the second aircraft hit the WTC (see 9:03 a.m. September 11, 2001), there is apparently no increase in the level of security at the Capitol building. Fox News correspondent Brian Wilson will later recall that when reporting from the Capitol building around this time, he is “talking about the first lady being in the Capitol and saying that I had not seen any signs of tighter security in the building.”
Reporter Surprised at Plan to Hold a Photo Op - Wilson is also surprised that, although the Senate hearing Bush was scheduled to attend has been canceled, the first lady is still going to make a public appearance. He will comment that “they were (incredibly) trying to set up a brief photo opportunity.” [Gilbert et al., 2002, pp. 64; 9/11 Commission, 7/24/2004, pp. 8] (Wilson is presumably referring to Laura Bush’s appearance before reporters and cameras alongside Senators Edward Kennedy (D-MA) and Judd Gregg (R-NH), which takes place at 9:41 a.m. (see 9:41 a.m. September 11, 2001).

Shortly after he learns a second plane has hit the World Trade Center, United Airlines flight dispatcher Ed Ballinger takes the initiative to begin sending a warning message to the flights he is monitoring, including Flight 93 and Flight 175 (although this aircraft has already crashed). [9/11 Commission, 7/24/2004, pp. 11; 9/11 Commission, 8/26/2004, pp. 26 and 37] Ballinger is responsible for monitoring United’s aircraft flying from the East Coast to the West Coast. He has 16 such flights he is in charge of. [Chicago Daily Herald, 4/14/2004] He sends out a text message to his airborne flights: “Beware any cockpit intrusion… Two aircraft in NY hit [World] Trade Center builds.” [9/11 Commission, 7/24/2004, pp. 11; 9/11 Commission, 8/26/2004, pp. 26] Although United Airlines has suspected Flight 175 as being hijacked since around 9:00 a.m. (see Shortly Before 9:00 a.m. September 11, 2001), Ballinger is still responsible for multiple flights. (In contrast to United, American Airlines has a policy that flight dispatchers should only manage the hijacked flight, and be relieved of responsibility for their other flights.) [9/11 Commission, 7/24/2004, pp. 455-456] Ballinger’s warning is therefore sent out to his aircraft in groups, and will not be sent to Flight 93 until 9:23 a.m. (see 9:23 a.m.-9:26 a.m. September 11, 2001). Unaware that it was the second plane that hit the WTC, Ballinger will also send the message to Flight 175 (see 9:23 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 26 and 37] Ballinger begins sending out these warnings two minutes before United Airlines instructs its dispatchers to warn their flights to secure their cockpit doors (see 9:21 a.m. September 11, 2001). [9/11 Commission, 1/27/2004; 9/11 Commission, 7/24/2004, pp. 455] According to the 9/11 Commission, his text message represents “the first occasion on 9/11 when either American or United sent out such a warning to their airborne aircraft.” [9/11 Commission, 8/26/2004, pp. 37] Ballinger will later recall: “As soon as I had a grasp of what was going on… I sent [the warning] out immediately. It was before [Transportation Secretary Norman] Mineta, and even before the airlines told us to alert the crews.” [Chicago Daily Herald, 4/14/2004]

United Airlines Flight 23, a Boeing 767 bound from JFK International Airport in New York to Los Angeles, cancels its takeoff and may thus avoid becoming the morning’s fifth hijacked plane. It was scheduled to depart at 8:30 a.m., but was late in pushing back from the gate and is still waiting in line to take off. [Associated Press, 9/13/2001; New York Times, 10/20/2001] The plane’s pilots, Tom Mannello and Carol Timmons, have heard a report over their radio that a plane has flown into the World Trade Center. They then receive a text message from United Airlines dispatcher Ed Ballinger, which reportedly states: “We have gone to heightened security. Do not open cockpit doors. Secure the cockpit.” [Spencer, 2008, pp. 102-103] This is presumably the message Ballinger sent out at 9:19 (see 9:19 a.m. September 11, 2001), though it seems to be more like a description of the message he sends out at 9:32 (see 9:32 a.m.-9:33 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 37 and 39]
Pilots Alarmed at Warning - Having never received a warning like this before, the pilots are alarmed. Timmons starts barricading the cockpit door with their suitcases while Mannello grabs the crash ax for protection. Mannello calls the plane’s lead flight attendant to inform her of the threat, and tells her not to open the cockpit door under any circumstances. Soon afterwards, she calls back and informs him: “We [the plane’s flight attendants] just think you should know this because we think it is unusual. We have four young Arab men sitting in first class this morning.” [Spencer, 2008, pp. 103] (Other accounts will claim there are three or even six suspicious passengers on the flight. [Associated Press, 9/13/2001; Chicago Daily Herald, 4/14/2004] ) Mannello hasn’t been told what the reported threat is about or if it relates to Arabs, so simply thanks the attendant for the information. Minutes later, the pilots receive a radio message from ground control, announcing, “All aircraft, be advised that the airport is now closed.” A subsequent message announces the airport is being evacuated. Mannello decides to move his aircraft back to the terminal. [Spencer, 2008, pp. 103-104]
Arab Passengers Become Aggressive - After the passengers are told their flight has been canceled, the Arab men become upset. They stand up and start urgently consulting with each other, and then refuse to return to their seats. [Associated Press, 9/13/2001; New York Times, 10/20/2001] One official will later describe: “These guys got belligerent, and said something like, ‘We’ve got to be on this plane.’ They expressed a desire to remain on the plane and resisted getting off.” [New York Times, 9/14/2001] According to the Associated Press, “The argument with a member of the flight crew became so heated that the crew member called airport security. But before security arrived, the men had vanished.” [Associated Press, 9/13/2001]
Evidence Indicates Plans for Hijacking Plane - Authorities will later check the men’s unclaimed baggage and find box-cutters, copies of the Koran, and al-Qaeda instruction sheets. [Chicago Daily Herald, 4/14/2004; Spencer, 2008, pp. 105] In 2002, apparently referring to this incident, Lieutenant General Ken Pennie, the deputy commander of NORAD, will state, “We suspect there might have been more than just the four aircraft involved” as targets for the 9/11 attacks. [Globe and Mail, 6/13/2002] The FBI will investigate this incident and go through the flight manifest to determine the names of the Arab men, who are believed to have had ticketed reservations. [Associated Press, 9/13/2001; New York Times, 9/14/2001] Investigators will interview the plane’s crew nearly half a dozen times. But no information about the suspicious Arab passengers is ever released to the public. [Spencer, 2008, pp. 105] On September 14, it is reported that investigators believe at least one of these passengers was among a number of individuals taken into custody at JFK and La Guardia Airports the previous day (see September 13-14, 2001). [New York Times, 9/14/2001] However, these detained individuals are soon cleared of any connection with the events of 9/11 and are released. [Associated Press, 9/14/2001] In 2004, Representative Mark Kirk (R-IL) will say the suspicious Flight 23 passengers were never found and are likely still at large. [Chicago Daily Herald, 4/14/2004]

United Airlines issues a companywide order for its flight dispatchers to warn their flights to secure their cockpit doors. [9/11 Commission, 1/27/2004; 9/11 Commission, 7/24/2004, pp. 455] The airline’s air traffic control coordinator sends a message to all of the airline’s dispatchers, telling them: “There may be addnl [additional] hijackings in progress. You may want to advise your flts [flights] to stay on alert and shut down all cockpit access inflt [in flight]. Sandy per Mgmt.” United Airlines dispatchers began notifying their aircraft that planes had crashed into the World Trade Center at 9:03 (see 9:03 a.m. and After September 11, 2001). However, with the exception of one dispatcher (see 9:19 a.m. September 11, 2001), the airline has so far not sent any warnings to its aircraft. [9/11 Commission, 8/26/2004, pp. 36-37] United Airlines did not initially realize the second plane to hit the WTC was one of its own (see Between 9:10 a.m. and 9:20 a.m. September 11, 2001), and it is not until 9:22 that it notifies its dispatchers that UAL Flight 175 has been involved in “an accident” in New York (see 9:22 a.m. September 11, 2001).

Rich Miles, the manager of United Airlines’ System Operations Control center, located outside Chicago, issues an advisory to all United Airlines facilities, including the flight dispatchers. This advisory, which is issued under the name of UAL Chief Operating Officer Andy Studdert, states that Flight 175 has been involved in an accident in New York City, and that the airline’s crisis center has been activated. [Wall Street Journal, 10/15/2001; 9/11 Commission, 8/26/2004, pp. 26] This appears to be United Airlines’ first proper confirmation that Flight 175 has crashed.

Unaware that this aircraft has crashed, United Airlines flight dispatcher Ed Ballinger sends a warning message to Flight 175. The text message reads: “Beware any cockpit intrusion… Two aircraft in NY hit [World] Trade Center builds.” Ballinger began sending this text message to the 16 transcontinental flights he is monitoring at 9:19 a.m. (see 9:19 a.m. September 11, 2001). He is already aware that United Airlines suspects Flight 175 has been hijacked (see (9:01 a.m.-9:04 a.m.) September 11, 2001) and recently learned that a second plane has hit the World Trade Center, but does not yet know this was Flight 175.

Flight 93 makes its last normal communication with air traffic control before being hijacked, acknowledging a routine radio transmission from the FAA’s Cleveland Center. [9/11 Commission, 7/24/2004, pp. 28] Flight 93 checked in with the Cleveland Center a couple of minutes earlier (see 9:24 a.m.-9:25 a.m. September 11, 2001). At 9:27, the Cleveland controller, John Werth, alerts it to another aircraft 12 miles away and to its right, at 37,000 feet: “United 93, that traffic for you is one o’clock, 12 miles east, bound three-seven-zero.” Seconds later, Flight 93 responds, “Negative contact, we’re looking, United 93.” Less than a minute after this, the hijackers appear to enter Flight 93’s cockpit (see (9:28 a.m.) September 11, 2001).

John Werth.John Werth. [Source: CBS]Shortly after hearing strange noises from the cockpit of Flight 93, Cleveland air traffic controllers notice the plane has descended about 700 feet. John Werth, the controller who is handling the plane, tells the supervisor nearest to him, “I think we have another one [i.e., another hijacking].” He will repeatedly radio the cockpit over the next four minutes, asking the pilot to confirm the hijacking, but receive no response. At 9:30 a.m., Werth begins asking other nearby flights on his frequency if they’ve heard screaming; several say that they have. [Gregor, 12/21/2001 pdf file; 9/11 Commission, 7/24/2004, pp. 28; CBS News, 9/10/2006] The Cleveland Center immediately notifies United Airlines’ headquarters of the loss of communication with Flight 93 (see (9:30 a.m.) September 11, 2001). However, the FAA chain of command is apparently not also immediately informed.

Thomas Von Essen.Thomas Von Essen. [Source: Publicity photo]The Office of Emergency Management’s Emergency Operations Center (EOC) in World Trade Center Building 7 is evacuated in response to a report that more commercial planes are unaccounted for. [9/11 Commission, 7/24/2004, pp. 305] The EOC, which opened in 1999 (see June 8, 1999), is a state-of-the-art facility on the 23rd floor of WTC 7 that is intended to serve as a meeting place for city leaders in the event of an act of terrorism or other kind of crisis. [CNN, 6/7/1999; City of New York, 2/18/2001] Office of Emergency Management (OEM) officials activated it shortly after Flight 11 crashed into the North Tower of the WTC (see (Shortly After 8:46 a.m.) September 11, 2001). [Bylicki, 6/19/2003; 9/11 Commission, 7/24/2004, pp. 293]
Staffers Discussed Evacuation after the First Crash - Soon after the crash occurred, officials in the EOC “began discussing with OEM staff whether or not they should evacuate the building,” according to a report by Tricia Wachtendorf of the Disaster Research Center at the University of Delaware. [Wachtendorf, 2004, pp. 77] Richard Rotanz, deputy director of the OEM, and some other officials in the EOC conducted a “threat analysis” after the second hijacked plane crashed into the WTC, at 9:03 a.m. (see 9:03 a.m. September 11, 2001). [Urban Hazards Forum, 1/2002]
Staffers Want to Stay in the Operations Center - Personnel are reluctant to leave the EOC because in it they have “a tremendous amount of resources at their fingertips” and they are “best able to handle an emergency of this scale,” Wachtendorf will later write. Furthermore, there is no clear procedure to move to or establish an alternative operations center if it is abandoned. “I couldn’t think of where we would go if we left the EOC because at that time we didn’t have a backup facility,” one official will recall. There is, in fact, “no formalized evacuation plan for the EOC,” according to Wachtendorf. [Wachtendorf, 2004, pp. 77-79]
OEM Deputy Director Orders the Evacuation - However, Richard Bylicki, a police sergeant assigned to the OEM, was told during a call with the FAA that at least one other plane, in addition to the two that hit the Twin Towers, is unaccounted for and possibly heading for New York (see (9:30 a.m.) September 11, 2001), and he passed this information on to Rotanz. [Bylicki, 6/19/2003] Rotanz was given the same warning by a Secret Service agent who works in WTC 7. [Urban Hazards Forum, 1/2002; 9/11 Commission, 7/24/2004, pp. 305] Based on this information, he “surmised that [WTC 7] was potentially the next target,” Bylicki will recall. He consequently now orders all OEM employees to leave the building. [Bylicki, 6/19/2003; 9/11 Commission, 4/7/2004] A Secret Service agent, presumably the one who told Rotanz about the additional unaccounted-for planes, also reportedly advises EOC personnel to evacuate. He says, “There’s a reported third plane headed toward the East Coast and we’re warning everybody to vacate the building,” Fire Department Captain Abdo Nahmod will recall. [Journal of Emergency Medical Services, 9/2011, pp. 42 pdf file]
Some Liaisons Have Come to the Operations Center - Various city agencies were contacted after the EOC was activated and instructed to send their designated representatives to the center. None of these representatives have arrived by the time the EOC is evacuated, according to the 9/11 Commission Report. [9/11 Commission, 5/18/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 293, 305] However, contradicting this claim, a number of emergency responders will recall arriving at the EOC before it is evacuated, to serve as representatives for their agencies. [City of New York, 10/11/2001; City of New York, 10/25/2001; City of New York, 12/4/2001; Journal of Emergency Medical Services, 9/2011, pp. 42 pdf file]
Staffers Are Initially Slow to Leave - Personnel reportedly do not initially respond to the evacuation order with a sense of urgency. They “calmly collected personal belongings and began removing OEM records,” a report by the Mineta Transportation Institute will state. But they are subsequently “urged to abandon everything and leave the building quickly.” [Jenkins and Edwards-Winslow, 9/2003, pp. 16 pdf file] After evacuating from the EOC, they assemble in the lobby of WTC 7 and await further instructions over radio. [Bylicki, 6/19/2003] Most of them think they are only temporarily abandoning their facility and expect to return to it later in the day. They do not anticipate WTC 7 being affected by fires (see 4:10 p.m. September 11, 2001) and then collapsing late this afternoon (see (5:20 p.m.) September 11, 2001). [Wachtendorf, 2004, pp. 84]
Fire Commissioner Will Be Surprised That the Center Is Evacuated - Fire Commissioner Thomas Von Essen will be surprised when he finds that the EOC has been evacuated, since the center was designed for dealing with a crisis like the one currently taking place. “I thought that was where we should all be because that’s what [it] was built for,” he will comment. He will arrive at WTC 7 looking for Mayor Rudolph Giuliani shortly before 9:59 a.m., when the South Tower collapses (see 9:59 a.m. September 11, 2001). When he learns that the EOC has been evacuated, he will think: “How ridiculous. We’ve got a 13-million-dollar command center and we can’t even use it.” He will say in frustration: “How can we be evacuating OEM? We really need it now.” [Essen, 2002, pp. 26; Fink and Mathias, 2002, pp. 230]
Time of the Evacuation Is Unclear - It is unclear exactly when the EOC is evacuated. The order to evacuate is issued at “approximately 9:30” a.m., according to the 9/11 Commission Report. [9/11 Commission, 7/24/2004, pp. 305] But, according to a report by the National Institute of Standards of Technology, the evacuation occurs slightly later than this, at “approximately 9:44 a.m.” [National Institute of Standards and Technology, 9/2005, pp. 109] Other accounts will suggest it may even have taken place before the second attack on the WTC occurred (see (Soon After 8:46 a.m.-9:35 a.m.) September 11, 2001 and (Shortly Before 9:03 a.m.) September 11, 2001). [Barrett and Collins, 2006, pp. 34; Dylan Avery, 2007] Many people in the rest of WTC 7 left the building earlier on, around the time of the second attack (see (9:03 a.m.) September 11, 2001).

After United Airlines learns that Flight 93 is not responding to air traffic controllers, it notifies its flight dispatchers of this, and two of its employees try to contact the flight. At about 9:30, the FAA’s Cleveland Center informed the United Airlines headquarters, near Chicago, that Flight 93 was not responding to attempted radio contacts (see (9:30 a.m.) September 11, 2001). At 9:31, officials at the headquarters inform the airline’s dispatchers—who are responsible for monitoring aircraft in flight—that there is a potential problem with Flight 93. Over the next minute, United’s air traffic control coordinator and another of its employees each send a text message to Flight 93, stating, “ATC looking for you on 133.37.” Flight 93 does not respond to these or any subsequent text messages.

United Airlines flight dispatcher Ed Ballinger sends a warning message to the flights he is monitoring, which include Flight 93. [9/11 Commission, 8/26/2004, pp. 39] Ballinger is responsible for monitoring 16 transcontinental flights. [Chicago Daily Herald, 4/14/2004] Beginning at 9:32, he sends out a text message to these flights: “High security alert. Secure cockpit.” He presumably sends this in response to United Airlines’ notification a minute earlier that there is a potential problem with Flight 93 (see 9:31 a.m.-9:32 a.m. September 11, 2001). Ballinger’s message is transmitted to Flight 93 at 9:33, but the plane does not respond. Ballinger apparently informs his colleagues of this lack of response: United Airlines Chief Operating Officer Andy Studdert will later tell the 9/11 Commission that at “approximately 9:30, a United dispatcher reports that we cannot reach Flight 93.” [9/11 Commission, 1/27/2004; 9/11 Commission, 8/26/2004, pp. 39] Ballinger previously sent out a message at 9:19, warning his flights to “Beware any cockpit intrusion” (see 9:19 a.m. September 11, 2001).

Bill Grimes.Bill Grimes. [Source: Lori A. Bultman / US Air Force]Colonel Bill Grimes receives a call in which he is asked about getting the Predator drone, a remotely controlled, unmanned plane, ready to fly over Afghanistan. [Whittle, 2014, pp. 235] Grimes is the director of Big Safari, a highly secretive Air Force program based at Wright-Patterson Air Force Base in Ohio that specializes in modifying standard Air Force aircraft for time-sensitive and highly classified operations. [Defense Update, 5/3/2013; Wired, 12/17/2015] He was in his office at Wright-Patterson this morning when a colleague told him an airplane had crashed into the World Trade Center. He then joined others watching the television coverage of the incident in the conference room next to his office and saw the second hijacked plane crashing into the WTC, at 9:03 a.m. (see 9:03 a.m. September 11, 2001). “Within a few minutes” of the second crash, according to journalist and author Richard Whittle, Grimes is called back to his office to take a call from Lieutenant Colonel Kenneth Johns, who is at Air Force headquarters at the Pentagon. Johns wants to know what needs to be done to get three Predators, and whatever is needed to fly them over Afghanistan, ready to go. But just as the two men start discussing the matter, Johns says he will have to call again later, since the Pentagon is being evacuated. This evacuation is presumably in response to the attack on the Pentagon, which occurs at 9:37 a.m. (see 9:37 a.m. September 11, 2001). Grimes says he will have answers by the time the two men talk again. [Whittle, 2014, pp. 235] He will subsequently call members of his team, and tell them to pack their bags and prepare to deploy. He will instruct them to go to the airfield at Palmdale, California, where a C-17 cargo plane will arrive soon to pick them up. Grimes will later write that he starts calling the members of his team “[m]ere moments after the second airliner crashed into the World Trade Center.” According to Whittle, he starts making the calls “shortly after” the second crash at the WTC. However, if his conversation with Johns occurs around the time of the Pentagon attack, he presumably only starts calling the members of his team after 9:37 a.m. A C-17 will set off tomorrow to fly three Predators, along with members of Grimes’s team, from California to Washington, DC (see September 12-14, 2001).

Secret Service executives implement an “emergency call-up” of all their agency’s personnel at some time after 9:37 a.m., when the Pentagon was hit, according to US News and World Report. The reason why the Secret Service did not call up all its personnel earlier on is unstated, as is the reason it decides to do so now. [US News and World Report, 12/1/2002] The Secret Service is responsible for protecting the nation’s “most visible targets,” including the president, the vice president, and the White House complex. [US Department of the Treasury, 5/8/2001; Office of Management and Budget, 7/2001, pp. 82 pdf file] Brian Stafford, the agency’s director, realized the US was under attack after the second plane hit the World Trade Center at 9:03 a.m. (see 9:03 a.m. September 11, 2001), and then activated the Director’s Crisis Center at Secret Service headquarters to manage the agency’s response (see (Shortly After 9:03 a.m.) September 11, 2001).

Stacia Rountree.Stacia Rountree. [Source: Vanity Fair]Colin Scoggins, the military liaison at the FAA’s Boston Center, contacts NORAD’s Northeast Air Defense Sector (NEADS) and incorrectly notifies it that another aircraft, Delta Air Lines Flight 1989, is a possible hijacking. [9/11 Commission, 2004; Vanity Fair, 8/1/2006] Boston Center previously called NEADS at 9:27 and said that Delta 1989 was missing (see 9:27 a.m. September 11, 2001). [North American Aerospace Defense Command, 9/11/2001; 9/11 Commission, 5/23/2003]
NEADS Technicians Respond - At NEADS, Stacia Rountree, the ID technician who takes Scoggins’s call, announces to her colleagues: “Delta ‘89, that’s the hijack. They think it’s possible hijack.… South of Cleveland.” The plane’s transponder is still on, and she adds, “We have a code on him now.” Rountree’s team leader, Master Sergeant Maureen Dooley, instructs: “Pick it up! Find it!” The NEADS technicians quickly locate Delta 1989 on their radar screens, just south of Toledo, Ohio, and start alerting other FAA centers to it. [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 177] NEADS mission crew commander Major Kevin Nasypany will be notified by his staff of the suspected hijacking at about 9:41 or 9:42 a.m. [9/11 Commission, 1/22/2004 pdf file] NEADS never loses track of Delta 1989. It will follow it on radar as it reverses course over Toledo, heads east, and then lands in Cleveland (see (10:18 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 28] It will order Air National Guard fighter jets from Selfridge and Toledo to intercept the flight (see (9:55 a.m.) September 11, 2001 and 10:01 a.m. September 11, 2001). [Spencer, 2008, pp. 178-179] But it will soon learn that Delta 1989 is not in fact hijacked. [9/11 Commission, 7/24/2004, pp. 28]
Cleveland Center, Not Boston, Handling Delta 1989 - Although Boston Center notifies NEADS of the suspected hijacking, Delta 1989 is in fact being handled by the FAA’s Cleveland Center. [USA Today, 8/13/2002; 9/11 Commission, 7/24/2004, pp. 10-12] Cleveland Center air traffic controllers suspected that Delta 1989 had been hijacked at around 9:30 a.m. (see (9:28 a.m.-9:33 a.m.) September 11, 2001), but apparently only informed the FAA’s Command Center, and not NEADS, of this. [USA Today, 8/13/2002] To explain why Boston Center alerts NEADS to the flight, the 9/11 Commission will later comment that, “Remembering the ‘we have some planes’ remark” (see 8:24 a.m. September 11, 2001), the Boston Center simply “guessed that Delta 1989 might also be hijacked.”
Similar to First Two Hijacked Planes - Like Flights 11 and 175, the two aircraft that have crashed into the World Trade Center (see 8:46 a.m. September 11, 2001 and 9:03 a.m. September 11, 2001), Delta 1989 took off from Boston’s Logan Airport. [9/11 Commission, 7/24/2004, pp. 27-28] According to the New York Times, it left there at about the same time as Flights 11 and 175 did, meaning around 8:00 to 8:15 a.m. [New York Times, 10/18/2001; 9/11 Commission, 7/24/2004, pp. 32] Like those two aircraft, it is a Boeing 767. [USA Today, 8/13/2002; 9/11 Commission, 7/24/2004, pp. 27-28] But, unlike those flights, its transponder has not been turned off, and so it is still transmitting a beacon code. [9/11 Commission, 7/24/2004, pp. 28; Vanity Fair, 8/1/2006] It is unclear what Delta 1989’s intended destination is. According to some accounts, like Flights 11 and 175 were, it is bound for Los Angeles. [Associated Press, 9/11/2001; New York Times, 10/18/2001; USA Today, 8/13/2002; Arizona Daily Star, 9/24/2007; Spencer, 2008, pp. 167] Other accounts will say that its destination is Las Vegas. [9/11 Commission, 7/24/2004, pp. 28; Vanity Fair, 8/1/2006] Personnel at NEADS are apparently informed that Las Vegas is the intended destination. Around this time, one member of staff there tells her colleagues that the flight is “supposed to go to Vegas.” [North American Aerospace Defense Command, 9/11/2001]
One of Numerous Incorrect Reports - The 9/11 Commission will comment: “During the course of the morning, there were multiple erroneous reports of hijacked aircraft (see (9:09 a.m. and After) September 11, 2001). The report of American 11 heading south was the first (see 9:21 a.m. September 11, 2001); Delta 1989 was the second.” [9/11 Commission, 7/24/2004, pp. 28]

Alice Hoglan, the mother of Mark Bingham, a passenger on Flight 93, informs the FBI that her son has just phoned her from the plane, and then calls Bingham’s cell phone and leaves two voicemail messages. [Federal Bureau of Investigation, 9/17/2001; Barrett, 2002, pp. 157-158] Alice Hoglan is currently staying at the home of her brother, Vaughn Hoglan, and his wife in Saratoga, California. [Longman, 2002, pp. 129; San Francisco Chronicle, 9/10/2003] Bingham has just called her and told her his flight was taken over by three men who said they had a bomb, but the call got broken off after less than three minutes (see (9:37 a.m.) September 11, 2001). [Federal Bureau of Investigation, 9/11/2001; 9/11 Commission, 5/13/2004 pdf file; 9/11 Commission, 8/26/2004, pp. 41, 99]
Bingham's Mother Realizes Flight 93 Will Likely Crash - No one in the Hoglan household was aware of the terrorist attacks in New York and at the Pentagon. But after the call from Bingham ends, Vaughn Hoglan switches on the television to see if there is any news about Flight 93 and the family sees, for the first time, the recorded footage of Flight 175 crashing into the World Trade Center (see 9:03 a.m. September 11, 2001). [BBC, 12/2001; Barrett, 2002, pp. 157] Alice Hoglan then realizes the hijacking of Flight 93 is part of a “grand and ugly scheme,” and that her son’s plane will likely crash, too. [San Francisco Chronicle, 1/28/2005; San Jose Mercury News, 9/10/2011]
Bingham's Mother Tells the FBI about the Hijacking - Being a flight attendant with United Airlines, she calls her airline to ask about her son’s plane. [Los Gatos Patch, 8/25/2011] However, she will later recall, all she gets is a recorded message, which states, “United Flight 93 left Newark at 8:01 a.m. and will arrive San Francisco, Gate 82, at 11:19 a.m.” [BBC, 12/2001] She also calls 9-1-1 to report what has happened. She is put through to the San Francisco division of the FBI and speaks to an agent there. [Federal Bureau of Investigation, 9/17/2001] The agent asks her a series of questions about the hijackers on Flight 93, but she is unable to answer them.
Bingham's Mother Leaves Messages for Her Son - Alice Hoglan then tries calling her son twice on his cell phone, intending to let him know the full scale of the attack that his plane’s hijacking is part of. On both occasions, she has to leave messages on his voicemail. She makes the first call at 9:54 a.m. (Because she is flustered, she miscalculates the East Coast time by an hour during the call and also mistakenly says Flight 93 might be used as a “target” rather than as a “weapon.”) She says: “Mark, this is your mom. It’s 10:54 a.m. [Eastern Time]. The news is that it’s been hijacked by terrorists. They are planning to probably use the plane as a target to hit some site on the ground. So, if you possibly can, try to overpower these guys if you can, ‘cause they will probably use the plane as a target. I would say go ahead and do everything you can to overpower them, because they’re hellbent. Try to call me back if you can. You know the number here. Okay, I love you sweetie. Bye.” A minute or so later she calls Bingham’s cell phone again and leaves a second, similar message. Among other things, she urges her son to “group some people and perhaps do the best you can to get control of [the plane].” [Barrett, 2002, pp. 157-158; San Jose Mercury News, 9/10/2011; McMillan, 2014, pp. 122] Bingham will never receive these messages. [ABC News, 3/30/2002] His plane will crash in a field in Pennsylvania at 10:03 a.m. (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001).

Edward Felt. [Source: Family photo]An emergency call is received at the 911 center in Westmoreland County, Pennsylvania, from Edward Felt, a passenger on Flight 93. [Pittsburgh Tribune-Review, 9/8/2002] Felt makes the 911 call using his cell phone. [9/11 Commission, 8/26/2004, pp. 45; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] It is answered by dispatcher John Shaw, on a line at the center specifically for incoming cell phone calls. [Federal Bureau of Investigation, 9/12/2001 pdf file; Longman, 2002, pp. 193] Glenn Cramer, a supervisor at the 911 center, hears Shaw responding to the caller, “You are what hijacked?” and consequently picks up a phone that allows him to listen in on the rest of Felt’s call. [Federal Bureau of Investigation, 9/12/2001 pdf file; Pittsburgh Post-Gazette, 12/7/2001]
Call Center Workers Mishear Name - Felt identifies himself. Shaw and Cramer apparently mishear, and both will recall that he says his name is “Ed Wart.” [Federal Bureau of Investigation, 9/11/2001 pdf file; Federal Bureau of Investigation, 9/12/2001 pdf file] (The FBI will initially refuse to disclose the caller’s name to the press, but he is later revealed to have been Edward Felt, a 41-year-old engineer from New Jersey. [Washington Post, 9/12/2001; Longman, 2002, pp. 194; New York Times, 3/27/2002] ) Felt says, “We are being hijacked, we are being hijacked!” He repeatedly states that his call is not a hoax. [ABC News, 9/11/2001; Associated Press, 9/11/2001] He says the passengers need help immediately. [Federal Bureau of Investigation, 9/11/2001 pdf file]
Felt Answers Questions about His Flight, but Does Not Describe Hijackers - Shaw asks Felt standard questions, such as where is he? What type of plane is he on? And what has happened? [Pittsburgh Post-Gazette, 9/11/2002] Felt tells Shaw his cell phone number and says he is on United Airlines Flight 93 from Newark to San Francisco. [Longman, 2002, pp. 193-194; Pittsburgh Tribune-Review, 9/11/2002; United States of America v. Zacarias Moussaoui, a/k/a Shaqil, a/k/a Abu Khalid al Sahrawi, Defendant., 4/11/2006 pdf file] He says he is locked in the bathroom of the plane, but does not say if this is its front or rear bathroom. He does not say anything about how many hijackers are on board, nor make any statements about any weapons the hijackers may possess. [Federal Bureau of Investigation, 9/12/2001 pdf file] Nor does he mention any attempt by the passengers to regain control of the plane. [Longman, 2002, pp. 196]
Felt Describes 'Lots of Passengers,' though Plane Is Mostly Empty - Shaw will recall to the FBI that Felt tells him the plane is loaded with numerous passengers. [Federal Bureau of Investigation, 9/11/2001 pdf file] Glenn Cramer will similarly tell the FBI that Felt describes “lots of passengers” on board. [Federal Bureau of Investigation, 9/12/2001 pdf file] Yet there are only 37 passengers (including the four hijackers) on Flight 93, constituting just 20 percent of its passenger capacity of 182.

We’re going down.” [New York Times, 3/27/2002; Pittsburgh Tribune-Review, 9/11/2002] Cramer will say that Felt describes an explosion on the aircraft and smoke coming from it, but others—including Shaw—will deny this (see (Between 9:58 a.m. and 9:59 a.m.) September 11, 2001).

Call Ends after One Minute - Shaw will tell the FBI the call lasts “less than five minutes” before the line disconnects. [Federal Bureau of Investigation, 9/11/2001 pdf file] According to other accounts, it lasts just over one minute. [Dayton Daily News, 9/12/2001; Longman, 2002, pp. 197; Pittsburgh Tribune-Review, 9/8/2002; Valley News Dispatch, 9/11/2002] After the call ends, other employees at the Westmoreland County 911 center are instructed to notify the FBI and the FAA about it.

Paula Pluta, a resident of Stonycreek Township, Pennsylvania, sees Flight 93 crashing behind some trees about 1,500 yards from her home and then calls 9-1-1, becoming the first person to call the emergency services to report the crash. [Pittsburgh Tribune-Review, 9/12/2001; East Bay Times, 9/10/2005] Pluta is at her home, watching television, unaware of the terrorist attacks on the World Trade Center and at the Pentagon. Everything has been quiet and normal. Suddenly, though, her house starts to vibrate, and things in it start rattling and shaking. She hears a roar coming from the skies above her that gets louder and louder. “I heard this noise like a dive bomber; you know, one of those planes they use in war,” she will later recall. When she looks out the living room window, though, she sees nothing unusual outside. She then goes out onto the front porch. From there, she sees a “silver streak” plummeting toward the ground at an angle of about 45 degrees. “It looked like a silver bullet,” she will describe. [Los Angeles Times, 9/12/2001; McMillan, 2014, pp. 106; Friends of Flight 93 National Memorial, 3/17/2016] Flight 93 crashes into the ground at 10:03 a.m. (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001). [New York Times, 9/9/2011; National Park Service, 5/2013, pp. 13 pdf file] Pluta is unable to see the impact, since the plane disappears behind a line of trees before hitting the ground, but she feels the ground shaking when the plane crashes. “It hit so hard that it almost took my feet out from underneath me,” she will recall. [Los Angeles Times, 9/12/2001; McMillan, 2014, pp. 106; Friends of Flight 93 National Memorial, 3/17/2016] She also sees a huge fireball about 150 feet up in the air and a plume of smoke coming from behind the trees. [Chicago Tribune, 9/12/2001; National Park Service, 3/2017, pp. 15 pdf file] The explosion damages the outside of her home. Pluta notices that a garage door has buckled and a latched window has been sucked open. She immediately calls 9-1-1 to report the incident. “Oh my God!” she tells the operator. “There was an airplane crash here!” She is the first of about 20 local residents to report the crash of Flight 93 to the authorities.

bullet Jon Meyer, a reporter with WJAC-TV, will later describe: “I was able to get right up to the edge of the crater.… All I saw was a crater filled with small, charred plane parts. Nothing that would even tell you that it was the plane.… There were no suitcases, no recognizable plane parts, no body parts. The crater was about 30 to 35 feet deep.” [Newseum et al., 2002, pp. 148]
bullet According to Mark Stahl, who goes to the crash scene: “There’s a crater gouged in the earth, the plane is pretty much disintegrated. There’s nothing left but scorched trees.” [Associated Press, 9/11/2001]
bullet Frank Monaco of the Pennsylvania State Police will comment: “If you would go down there, it would look like a trash heap. There’s nothing but tiny pieces of debris. It’s just littered with small pieces.” [Pittsburgh Post-Gazette, 9/12/2001]
bullet Scott Spangler, a photographer with a local newspaper, will recall: “I didn’t think I was in the right place. I was looking for a wing or a tail. There was nothing, just this pit.… I was looking for anything that said tail, wing, plane, metal. There was nothing.” [Newseum et al., 2002, pp. 149]
bullet Paula Pluta, a local resident who headed to the site promptly after the crash occurred, will describe seeing “[j]ust a big crater that looked… like something had gone into it, and it rolled the dirt up around and buried itself.” “I’m looking around for plane wreckage and there’s nothing,” she will recall, adding: “I just stood there in amazement. Where did this thing go?” [McMillan, 2014, pp. 107]
bullet Dave Berkebile, another local resident, arrives at the site shortly after Pluta does. However, he cannot see any large airplane parts there. “The biggest chunk of debris he identified,” according to journalist and author Tom McMillan, “was a cooling unit that was maybe eight inches by 12 inches.” [McMillan, 2014, pp. 107]
bullet According to Ron Delano, a local who rushes to the scene after hearing about the crash: “If they hadn’t told us a plane had wrecked, you wouldn’t have known. It looked like it hit and disintegrated.” [Pittsburgh Tribune-Review, 9/12/2001]
bullet Gabrielle DeRose, a news anchor with KDKA-TV, views the crash site from a hill overlooking it. She will comment: “It was very disturbing to think all the remains just disintegrated…. There were no large pieces of airplane, no human remains, no baggage.” [Sylvester and Huffman, 2002, pp. 160-161]
bullet Local assistant volunteer fire chief Rick King, who sees the crater at the crash site, will say, “Never in my wildest dreams did I think half the plane was down there.” King sends his men into the woods to search for the plane’s fuselage, but they keep coming back and telling him: “Rick. There’s nothing.” [Longman, 2002, pp. 216]
Bob Craig of the FBI’s evidence-gathering team will explain what is supposed to have happened when Flight 93 hit the ground. “Turn the picture of the second plane hitting the World Trade Center on its side, and, for all intents and purposes, the face of the building is the strip mine in Shanksville [where Flight 93 crashed],” he will say.

My first reaction, as a former utility employee, was that maybe someone shot a missile into the substation.” He says Flight 93 “did not come over my house. I don’t know what we heard.” [Kashurba, 2002, pp. 158-159] Joe Wilt, who lives a quarter-mile from the crash site, hears a “whistling like a missile, then a loud boom.” He says, “The first thing I thought it was, was a missile.” [Boston Globe, 9/12/2001; Washington Post, 9/12/2001] And Ernie Stuhl, the mayor of Shanksville, later says, “I know of two people - I will not mention names - that heard a missile. They both live very close, within a couple of hundred yards.… This one fellow’s served in Vietnam and he says he’s heard them, and he heard one that day.” [Philadelphia Daily News, 11/18/2001] Officials will emphatically deny that Flight 93 was shot down, as some people later suggest (see September 14, 2001). [Pittsburgh Tribune-Review, 9/14/2001; Longman, 2002, pp. 264] However, a number of witnesses report seeing a small, white jet plane near the crash site, around the time Flight 93 reportedly goes down (see (Before and After 10:06 a.m.) September 11, 2001).

Richard Belme.Richard Belme. [Source: CNN]A United Airlines aircraft maintenance officer working at a maintenance facility in London, England, receives a suspicious satellite phone call from an unknown aircraft, apparently made by the plane’s pilot, who sounds distraught, possibly as if he is being choked.
Caller Sounds Strange, Makes No Sense - The call lasts for about seven or eight sentences, but the maintenance officer is unable to make sense of what it is about. He will later recall that the caller sounds strange, and tell the 9/11 Commission that this is the “only phone call that he’d ever received of that nature in the 10 years he’s been on the job for United.” The maintenance officer presumes that the caller is the plane’s pilot, because this specific type of satellite phone call can only be made from the flight deck of a commercial airliner. However, the caller’s manner of talking is not professional. The number for the London facility would not have been programmed into the phone, so the caller would have needed to type it in.
Caller Possibly Being Choked - The maintenance officer subsequently contacts the United Airlines System Aircraft Maintenance Control (SAMC) at San Francisco International Airport to report the strange call. The FBI is already at the SAMC and is made aware of his report. It is informed that the maintenance officer has said the caller from the plane “sounded as if they were being choked.” However, when he is interviewed by the 9/11 Commission in November 2003, the maintenance officer will state that “it is difficult to say whether or not the pilot was getting choked.” He will say he “doesn’t believe this to be the case and doesn’t recall reporting this,” although he will indicate that it is “possible he previously told someone that it sounded like the person was being choked.”
Origin of Call Unknown - The suspicious call comes up as “registration number unknown.” However, the maintenance officer recognizes it as coming from what he will call a “Sat 7 phone,” because, he will say, “the background noise was characteristic of that type of satellite call.” Typically, Boeing 767s and 777s have the equipment to make “Sat 7” calls, although the maintenance officer believes the call is most likely from a 777. The United Airlines legal department will subsequently tell the maintenance officer that “it would be possible to find the station that placed the call, because United must have a record of the phone call.” Satellite phone communication is expensive and each call is itemized when paid for. However, a 9/11 Commission memorandum in November 2003 will state that, at that time, the origin of the call “is still unknown.”
Call Unrelated to Two United Airlines Hijackings - According to the maintenance officer, the call is not tape recorded. But according to Richard Belme, a manager at the SAMC, the call is recorded but then only stored for a short time, maybe three months. The maintenance officer’s notes from this day will subsequently be shredded. The 9/11 Commission will conclude that the suspicious call could not have come from either of the two hijacked United Airlines flights because it does not coincide with the timeframe of those flights. Furthermore, United Airlines Flight 93 was a Boeing 757 and so would not have been equipped with the type of phone necessary to make the call. In mid-2003, the aircraft maintenance officer will be told that “this issue [is] over.” [Federal Bureau of Investigation, 9/11/2001; 9/11 Commission, 11/21/2003 pdf file; 9/11 Commission, 11/21/2003 pdf file]

[Kashurba, 2002, pp. 60] Due to the criminal nature of the crash, the FBI becomes lead authority for the investigation of the site. Attempts are made to have the area declared a federal disaster, but these are unsuccessful. [DMORT National News, 1/2002] For about two weeks, the FBI’s evidence recovery team of about 150 agents goes over the site with sifters, filtering evidence from the soil. It recovers about 510 pounds of human remains. [Longman, 2002, pp. 259; Age (Melbourne), 9/9/2002] Despite the lack of wreckage reported by those first at the crash scene (see (After 10:03 a.m.) September 11, 2001), the FBI claims that it recovers 95 percent of the plane. The largest piece found, it says, is a seven-foot-long piece of the fuselage skin, including four windows. With the exception of the two black boxes, all wreckage is passed on to United Airlines. Asked what United will do with this, a spokeswoman says, “I don’t think a decision has been made… but we’re not commenting.” [CNN, 9/24/2001; Pittsburgh Post-Gazette, 9/25/2001] While conducting its investigation of the crash site, the FBI overrules a plan to carefully map the area and mark the positions of debris so as to determine exactly how Flight 93 crashed, claiming this would be too time-consuming (see September 16, 2001). [Longman, 2002, pp. 262] After it completes its work, the site becomes the responsibility of the county coroner, who continues the search for remains. [Longman, 2002, pp. 258-259]

Flight 93’s flight data recorder, found at the crash site in Shanksville.Flight 93’s flight data recorder, found at the crash site in Shanksville. [Source: US District Court for the Eastern District of Virginia, Alexandria Division]Around 4:50 p.m. on September 13, investigators discover the flight data recorder from Flight 93, one of the plane’s two “black boxes.” It is buried about 15 feet down in the main crater at the crash site, near Shanksville, Pennsylvania. Around 8:25 p.m. the following evening, the other ‘black box’—the plane’s cockpit voice recorder—is found about 25 feet below ground in roughly the same spot. [Pittsburgh Post-Gazette, 9/13/2001; Pittsburgh Post-Gazette, 9/15/2001; Longman, 2002, pp. 217] The flight data recorder monitors airplane functions like its speed and altitude, while the cockpit voice recorder picks up conversations in the plane’s cockpit. [Pittsburgh Post-Gazette, 9/14/2001] Both are mounted in a plane’s tail. They are encased in very strong materials, like titanium, and insulated so as to withstand a crash impact. [BBC, 9/15/2001] Wells Morrison, the FBI’s second in command at the Flight 93 crash scene, later comments, “It was strange. The black boxes are right next to each other on the aircraft, but one was found thirteen feet deeper into the crater than the other.… We were surprised, quite honestly, that we didn’t find them sooner.” [Kashurba, 2002, pp. 109 and 115] The cockpit voice recorder is sent to the National Transportation Safety Board (NTSB) in Washington, and then on to its manufacturer, Honeywell, to try to extract information from it. [CBS News, 9/16/2001; Pittsburgh Post-Gazette, 11/4/2001] It is supposedly the only one from the four hijacked flights to have survived the crash impact and ensuing fire. [9/11 Commission, 7/24/2004, pp. 456] In April 2002, the 31-minute recording from it is played in private to victims’ relatives (see April 18, 2002). It will be played in public for the first time in April 2006, during the trial of Zacarias Moussaoui (see April 12, 2006). [CNN, 4/13/2006]

Officials deny that Flight 93 was shot down, but propose the theory that the hijackers had a bomb on board and blew up the plane.

A report suggests the crash site of Flight 93 is being searched and recorded in 60 square-foot grids. [News Journal (Wilmington, DE), 9/16/2001] This approach is preferred by Wallace Miller, the local coroner, and Dennis Dirkmaat, a forensic anthropologist involved in searching the crash site. According to journalist and author Jere Longman, “The distribution patterns developed from such precise marking of airplane parts, remains and personal effects might have told them such things as exactly how the airplane struck the ground. Theoretically, by associating the location of particular remains with the location of parts of the airplane, they may have also gained some clues about which passengers had rushed the cockpit.” However, almost a year later Longman reports that this approach was not followed: “The FBI overruled them, instead dividing the site into five large sectors. It would be too time-consuming to mark tight grids, and would serve no real investigative purpose, the bureau decided. There was no mystery to solve about the crash. Everybody knew what happened to the plane.” [Longman, 2002, pp. 262] While the FBI claims there is no mystery, some news articles suggest the plane was shot down. (For example, [Philadelphia Daily News, 11/15/2001; Independent, 8/13/2002] ) In addition, at the time of this decision, investigators are still considering the possibility that a bomb might have destroyed the plane (see September 14, 2001). Unlike every other major airplane crash in modern history, no National Transportation Safety Board (NTSB) investigation is being conducted into the crash of Flight 93 (see After September 11, 2001).

The North American Aerospace Defense Command (NORAD) releases a chronology of the events of September 11 and its response to the terrorist attacks that day, but the accuracy of this account will later be challenged by the 9/11 Commission. [North American Aerospace Defense Command, 9/18/2001; 9/11 Commission, 7/24/2004, pp. 34; 9/11 Commission, 7/29/2004]
NORAD Learned of First Hijackings Too Late to Defend the WTC - The chronology provides the times at which NORAD’s Northeast Air Defense Sector (NEADS) was alerted to the hijackings and when fighter jets were scrambled in response to the hijackings. It states that the Federal Aviation Administration (FAA) notified NEADS about Flight 11, the first hijacked aircraft, at 8:40 a.m. In response, the order was given to scramble two F-15 fighters from Otis Air National Guard Base in Cape Cod, Massachusetts, at 8:46 a.m. (see 8:46 a.m. September 11, 2001), the same time that Flight 11 crashed into the World Trade Center (see 8:46 a.m. September 11, 2001), and the fighters were airborne at 8:52 a.m. (see 8:53 a.m. September 11, 2001). The FAA notified NEADS about Flight 175, the second hijacked aircraft, at 8:43 a.m., according to the chronology. When Flight 175 crashed into the WTC at 9:03 a.m. (see 9:03 a.m. September 11, 2001), the chronology states, the Otis fighters were 71 miles away from New York.
Fighters Were Scrambled in Response to Flight 77 Hijacking - NEADS was alerted to Flight 77, the third hijacked aircraft, at 9:24 a.m., according to the chronology. In response, the order was given to scramble two F-16 fighters from Langley Air Force Base in Virginia (see 9:24 a.m. September 11, 2001) and these were airborne at 9:30 a.m. (see (9:25 a.m.-9:30 a.m.) September 11, 2001). But the F-16s were 105 miles from the Pentagon when it was hit at 9:37 a.m. (see 9:37 a.m. September 11, 2001). Regarding the fourth hijacked aircraft, Flight 93, the chronology gives “N/A” as the time the FAA alerted NEADS, but it also states that the FAA and NEADS discussed the flight on “a line of open communication.” At 10:03 a.m., when Flight 93 crashed in Pennsylvania (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001), the chronology states, the F-16s launched from Langley Air Force Base in response to the hijacking of Flight 77 were “in place to protect DC.” [North American Aerospace Defense Command, 9/18/2001]
9/11 Commission Disputes NORAD's Account - The 9/11 Commission Report, released in 2004, will highlight what it says are inaccuracies in NORAD’s timeline of the events of September 11. It will state that NORAD’s claim that NEADS was alerted to Flight 77 at 9:24 a.m. was incorrect. The notice NEADS received at that time, according to the report, was the incorrect claim that Flight 11 “had not hit the World Trade Center and was heading for Washington, DC” (see 9:21 a.m. September 11, 2001). “NEADS never received notice that American 77 was hijacked,” the report will state. “It was notified at 9:34 that American 77 was lost (see 9:34 a.m. September 11, 2001). Then, minutes later, NEADS was told that an unknown plane was six miles southwest of the White House” (see 9:36 a.m. September 11, 2001). The report will state that NORAD’s claim that the Langley fighters were scrambled in response to the notification about Flight 77 is also incorrect. Instead, it will state, the fighters were scrambled in response to the incorrect report that Flight 11 was still airborne and heading south. [9/11 Commission, 7/24/2004, pp. 34]
9/11 Commission Disputes NORAD's Account regarding Flights 175 and 93 - Furthermore, whereas NORAD’s chronology claims that NEADS discussed Flight 93 with the FAA on “a line of open communication,” the 9/11 Commission Report will state that NEADS “first received a call about United 93 from the military liaison at [the FAA’s] Cleveland Center at 10:07,” by which time the plane “had already crashed” (see 10:05 a.m.-10:08 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 30] And while NORAD states that the FAA notified NEADS about Flight 175 at 8:43 a.m., according to the report, the first notification came “in a phone call from [the FAA’s] New York Center to NEADS at 9:03” (see (9:03 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 23]
Military Has Been Slow to Provide Details of Its Response on September 11 - US military officials, according to the Washington Post, “have been slow to respond to press inquiries for a timeline that would establish the exact times that civil aviation authorities became aware of the hijackings, when US military commanders were notified, and when US fighter jets took to the air.” [Washington Post, 9/15/2001] On September 13, Air Force General Richard Myers was questioned about the military’s response to the 9/11 attacks before the Senate Armed Services Committee, but his answers were vague and confused (see September 13, 2001). [US Congress, 9/13/2001; Farmer, 2009, pp. 241-242] A day later, Major General Paul Weaver, director of the Air National Guard, provided reporters with details of the military’s response to the hijackings in an “impromptu hallway interview” at the Pentagon (see September 14, 2001).

[New York Times, 9/19/2001]
bullet There may have been an attempt to hijack United Airlines Flight 23 flying from JFK Airport, New York to Los Angeles around 9:00 a.m. Shortly after 9:00 a.m., United Airlines flight dispatcher Ed Ballinger sent out a warning about the first WTC crash to the flights he was handling (see 9:19 a.m. September 11, 2001). Because of this warning, the crew of Flight 23 told the passengers it had a mechanical problem and immediately returned to the gate. Ballinger was later told by authorities that six men initially wouldn’t get off the plane. When the men finally disembarked, they disappeared into the crowd and never returned. Later, authorities checked their luggage and found copies of the Koran and al-Qaeda instruction sheets. [Associated Press, 9/14/2001; Chicago Daily Herald, 4/14/2004] In mid-2002, a NORAD deputy commander says “we don’t know for sure” if Flight 23 was to have been hijacked. [Globe and Mail, 6/13/2002]

The FBI is said to be seeking a number of passengers who failed to board the same, rescheduled flights when the grounding order on commercial planes in the US was lifted. [BBC, 9/18/2001] The Independent points out suspicions have been fueled “that staff at US airports may have played an active role in the conspiracy and helped the hijackers to circumvent airport security.” They also note, “It is possible that at least some of the flights that have come under scrutiny were used as decoys, or as fallback targets.” [Independent, 9/25/2001]

Wayne Allard.Wayne Allard. [Source: Publicity photo]General Ralph Eberhart, the commander of the North American Aerospace Defense Command (NORAD), appears before the Senate Armed Services Committee and gives NORAD’s account of the events of September 11 and the military’s response to the terrorist attacks that day, but the 9/11 Commission will later find that some of the information he provides is incorrect. [US Congress. Senate, 10/25/2001; 9/11 Commission, 7/29/2004; Farmer, 2009, pp. 248] Eberhart was at NORAD headquarters at Peterson Air Force Base, Colorado, and then went to NORAD’s operations center in Cheyenne Mountain when the 9/11 attacks were taking place. [9/11 Commission, 3/1/2004 pdf file; 9/11 Commission, 3/1/2004] NORAD released a timeline of its response to the hijackings on September 18 (see September 18, 2001) and Eberhart’s testimony is consistent with that account. [North American Aerospace Defense Command, 9/18/2001]
Eberhart Says Fighters Were Scrambled in Response to First Hijacking - During the hearing, Eberhart tells Senator Wayne Allard (R-CO) that after the Federal Aviation Administration (FAA) alerted NORAD to the first hijacking, of Flight 11 (see (8:37 a.m.) September 11, 2001), NORAD ordered two F-15 fighter jets to take off from Otis Air National Guard Base in Cape Cod, Massachusetts (see 8:46 a.m. September 11, 2001), “almost simultaneously to the first crash” at the World Trade Center (see 8:46 a.m. September 11, 2001). Eberhart says that after he learned a plane had hit the WTC, he was initially unsure if that plane was Flight 11. “I’m sitting there hoping that someone has made a mistake; there has been an accident; that this isn’t the hijacked airplane [that hit the WTC], because there is confusion,” he recalls. He says he was informed that “it was a light commuter airplane” that hit the WTC, although, he says, it “didn’t look like that was caused by a light commuter airplane.”
Fighters Didn't Have Enough Time to Stop Second Crash - Eberhart says the FAA notified NORAD that there was “a second hijacked plane”—referring to Flight 175—“somewhere in there,” but although the Otis fighters were “flying toward New York” after being scrambled, they were still eight minutes away from the city when Flight 175 crashed into the WTC at 9:03 a.m. (see 9:03 a.m. September 11, 2001). “Tragically, there was just too much distance between Otis and New York City to get there in time,” Eberhart comments.
Eberhart Says NORAD Learned Flight 77 Was Hijacked before It Crashed - Eberhart says the first documented instance NORAD has of the FAA notifying it about Flight 77, the third aircraft to be hijacked, was at 9:24 a.m. After the hearing, in responses submitted for the record, Eberhart adds that the FAA notified NORAD’s Northeast Air Defense Sector (NEADS) that Flight 77 “was headed towards Washington, DC.” NEADS, he states, “then passed this information to NORAD’s Air Warning Center and Command Center in Cheyenne Mountain, and to the Continental US NORAD Region’s Regional Air Operations Center.”
Fighters Were Scrambled Too Late to Prevent the Pentagon Attack - Eberhart says NORAD launched two F-16 fighters from Langley Air Force Base in Virginia “as soon as” the FAA alerted it to the hijacking of Flight 77 (see 9:24 a.m. September 11, 2001). However, he says, these fighters were still “approximately 13 minutes away from Washington, DC, when that tragic crash [at the Pentagon] occurred.”
Eberhart Is Unaware of Reason for FAA's Delay in Contacting NORAD - Senator Carl Levin (D-MI) tells Eberhart: “The timeline that we’ve been given is that at 8:55 on September 11, American Airlines Flight 77 began turning east, away from its intended course. And at 9:10, Flight 77 was detected by the FAA radar over West Virginia heading east. That was after the two planes had struck the World Trade Center towers. Then 15 minutes later, at 9:25, the FAA notified NORAD that Flight 77 was headed toward Washington.” In light of this, he asks, “[D]o you know why it took 15 minutes for the FAA to notify NORAD?” Eberhart replies: “I do not know, sir, why it took that amount of time for FAA. I hate to say it, but you’ll have to ask FAA.” Senator John Warner (R-VA), who has an extensive military background, tells Eberhart he is “a little bit stunned that you don’t know why that delay occurred.” He continues, saying, “I would have thought by now all of you in this chain would have gone back, rehearsed these things, figured out what happened, what went wrong, so that we ensure it won’t happen again.” In his responses submitted for the record, Eberhart suggests possible reasons for the delay, stating that after the FAA lost radar contact with Flight 77, it “began to receive calls from outside agencies with reports of a possible downed aircraft. Additionally, the loss of radio contact with the aircraft added to the confusion.” Consequently, he states, “I believe the FAA was faced with conflicting information, which hindered them from making an accurate assessment of the actual location of the aircraft.”
Eberhart Says NORAD Was Following Flight 93 before It Crashed - Eberhart says NORAD was aware of the problems with Flight 93, the fourth hijacked plane, before it crashed in Pennsylvania (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001). He tells Allard that the FAA “knew before it deviated its flight pattern” that Flight 93 “was hijacked.” He says NORAD had been “trying to decide, initially, if that flight was going to continue west and if there was some other target for that flight. Was it Chicago? Was it St. Louis? And what might we do to launch an aircraft to intercept it.” But he says that after the FAA reacquired Flight 93 on radar, NORAD thought the plane “was headed probably for Washington, DC, but maybe New York.” He says NORAD decided at that time to keep the Otis and Langley fighters in place over New York and Washington. If another suspicious plane was approaching, he says, “our intent was to go out and meet that aircraft and destroy it if we needed to, if it entered either Washington, DC, or New York City airspace.” However, in his responses submitted for the record, Eberhart states that the “data/log entries received by NORAD from the FAA [after September 11] do not show a time or entry indicating the FAA specifically notified the Pentagon that United Airlines Flight 93 was hijacked.” He also states that NORAD “did not notify” the National Military Command Center (NMCC) at the Pentagon that Flight 93 had been hijacked.
9/11 Commission Disputes Some of Eberhart's Claims - Several claims Eberhart makes in the hearing will be contradicted by evidence uncovered by the 9/11 Commission during its investigation of the terrorist attacks. Whereas Eberhart says the military was first notified about the hijacking of Flight 77 at 9:24 a.m. and implies that this notification prompted the scrambling of fighters from Langley Air Force Base, according to John Farmer, the senior counsel to the 9/11 Commission, “[T]he first notification regarding American 77 occurred at 9:34, when it was reported ‘lost’” (see 9:34 a.m. September 11, 2001). [US Congress. Senate, 10/25/2001; Farmer, 2009, pp. 248-254] The notice NEADS received at 9:24 a.m., according to the 9/11 Commission Report, was the incorrect claim that Flight 11 “had not hit the World Trade Center and was heading for Washington, DC” (see 9:21 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 34] Consequently, Farmer will write, “the scramble of the Langley fighters did occur as an immediate reaction to a notification about hijacking, but that notification was not, as [Eberhart’s] testimony implies, a report that American 77 was hijacked, but the report that American 11 was still airborne and heading for Washington.” And while Eberhart claims the FAA told NEADS that Flight 77 was heading toward Washington, according to Farmer: “The FAA never notified NEADS that American 77 was heading for Washington, DC. There is no such notification recorded on any tape or in any log maintained at NEADS or at NORAD.” Furthermore, while Eberhart claims the military was following Flight 93 on radar before it crashed and was in position to shoot it down if it approached Washington, Farmer will write that “in fact, NEADS never located United 93 on radar, because the plane had already crashed by the time NEADS was notified.” [Farmer, 2009, pp. 251, 254-255]

He is in the US on an expired student visa. He is unemployed at the time of his arrest. Gurung claims that he was in a hurry and was unaware of the knives and other items in his luggage. But CNN reports that Gurung gave as his address an apartment building in Chicago that was also used by one of two terror suspects arrested on September 12, 2001 (see September 19, 2001 and After and October 20, 2001). This individual, Ayub Ali Khan (whose real name is apparently Syed Gul Mohammad Shah), lived in New Jersey but also used a Chicago address. A CNN government source says “many phone calls were made to and from that apartment, and credit card bills were paid from that address.” After being released by local police on bond, Gurung will be re-arrested the following day by the FBI for a weapons violation. Despite the apparent link to Ayub Ali Khan, the FBI denies any terror connection: “There is no allegation that this incident involves any suspected terrorist activity.” [CNN, 11/5/2001; CNN, 11/6/2001] Gurung will be convicted of a weapons charge in October 2002, and then deported.

The FBI allows relatives of passengers on Flight 93 to listen to the 31-minutes of tape from the plane’s cockpit voice recorder and see a written transcript of the recording. About 70 relatives do so. They are allowed to take notes, but not to make recordings because the tape might be used in the trial of Zacarias Moussaoui. [CNN, 4/19/2002; Guardian, 4/19/2002; Pittsburgh Post-Gazette, 4/21/2002] The San Francisco Chronicle responds: “Is there even a dollop of logic in that explanation? It’s like saying we can’t watch video of the planes crashing into the World Trade Center because that video might be used in a trial.” [San Francisco Chronicle, 6/3/2002] Much of the tape is reportedly unintelligible. According to the Pittsburgh Post-Gazette, “the voices were muddled and the ambient noise of the wind rushing by the speeding plane often made it impossible to distinguish individuals, even when they were yelling.” [Daily Telegraph, 4/20/2002; Pittsburgh Post-Gazette, 4/21/2002] New York Times reporter Jere Longman writes the book Among The Heroes based in part on interviews with relatives who hear the cockpit voice recording, along with several government officials and investigators. The recording reveals new details of the passengers’ struggle on board Flight 93, but the government still has not officially stated if it believes they took over the plane or not.

One of the key variables in the computer simulations used by the National Institute of Standards and Technology (NIST) (see (October 2002-October 2005)) to explain the WTC collapses is the speed of the aircraft that hit the towers. However, there is no consensus on how fast the planes were traveling. The first estimate was contained in an initial research paper by engineers Zdenek Bazant and Yong Zhou, who stated that the planes were traveling at 342 miles per hour. [Bazant and Zhou, 1/2002 pdf file] However, the Federal Emergency Management Agency (FEMA) and American Society of Civil Engineers (ASCE) report said that the plane that hit the North Tower was traveling at 470 miles per hour, whereas the plane that hit the South Tower was traveling at 590 miles per hour (see May 1, 2002). [Federal Emergency Management Agency, 5/1/2002, pp. 31] NIST initially estimates speeds of 435 miles per hour for the plane that hit the North Tower and 497 miles per hour for the plane that hit the South Tower. These estimates closely match figures produced by the Massachusetts Institute of Technology, which finds speeds of 429 miles per hour and 503 miles per hour for the two planes. However, NIST is dissatisfied with these results and does a second study, which finds speeds of 466 and 545 miles per hour. It then uses speeds of 472 and 570 miles per hour in its severe case model, on which its final report is based. In this model, the simulation of the planes traveling faster means greater damage to the towers’ structure, making them more unstable.

Matthys Levy.Matthys Levy. [Source: PBS]A report is made publicly available, which the Engineering News-Record calls the “most comprehensive study yet on the destruction of the World Trade Center.” The study was commissioned by WTC leaseholder Silverstein Properties Inc. to support a $7 billion insurance claim, and conducted by a team of engineers from several leading firms, including Weidlinger Associates, LZA Technology/Thornton-Tomasetti, and ARUPFire. It is intended to build on a previous study sponsored by FEMA (see May 1, 2002). The report’s findings are based on an analysis of original structural drawings, thousands of photos, and dozens of videos. Investigators used fire evaluation techniques and powerful computer software to simulate the condition of each tower at critical times between the planes’ impacts and the towers’ collapses. The earlier FEMA investigators had no access to such computer modeling. Matthys Levy, the chairman of Weidlinger Associates and one of the engineers on the study team, says, “The buildings had tremendous reserve capacity and that was reflected in all of the elements we analyzed. In fact, because there were so much excess capacity, the columns even in the impact floors did not buckle immediately, but failed as the result of the fire.” The report states that failure of the WTC’s steel floor supports (“trusses”) did not contribute to the collapses. Instead, the collapses were caused by the failure of steel structural columns that were either destroyed when the planes hit or lost fireproofing, leaving them vulnerable to the weakening effects of the ensuing fires. It says that debris and dust distributed by the plane crashes inhibited the fires, such that the average air temperatures on the impact floors were between 400 and 700°C (750-1,300°F): significantly lower than those associated with typical “fully developed” office fires. However, says Matthys Levy, “By the time the temperature inside the buildings reached 400 degrees, the steel would have lost approximately 50% of its strength. Eventually, gravity took over and the towers began to fall.” Then, according to the analysis led by researchers from LZA Technology/Thornton-Tomasetti, “Once collapse initiated in each tower, essentially all of the interior structure of the tower fell straight down with floors pancaking on top of one another. The network of perimeter steel columns and spandrels acted like a chute to funnel the interior contents into the tower footprint.” According to the computer simulations, the damage to the South Tower’s steel core columns was so severe that the tower should have collapsed immediately after the plane hit. Civil engineer John Osteraas says this incorrect result casts doubt upon some of the study’s predictions. The report concludes that the collapse of the South Tower did not cause or contribute to the subsequent collapse of the North Tower, thus supporting Silverstein Properties’ claim that the terrorist attack represented two occurrences, entitling it to two $3.5 billion insurance policy limits. A separate study commissioned by the insurers contradicts this (see October 23, 2002). The Silverstein report apparently does not examine the collapse of WTC Building 7, a 47-story skyscraper that also collapsed on 9/11 (see (5:20 p.m.) September 11, 2001). It has been passed on to the National Institute of Standards and Technology (NIST), which is undertaking its own investigation of the WTC collapses (see August 21, 2002).

Shyam Sunder.Shyam Sunder. [Source: NIST]The National Institute of Standards and Technology (NIST) releases nearly 500 pages of documents, detailing the latest findings of its investigation of the WTC collapses on 9/11. These include its hypotheses for the collapse sequences of each of the Twin Towers; details of their analysis of interviews with nearly 1,200 building occupants, emergency responders, and victims’ relatives; and information from their analysis of the emergency response and evacuation procedures. Their investigation into the collapses is based upon an analysis of thousands of photos and videos, examination of many of the elements used to construct the towers, and computer-enhanced modeling of the plane impacts and the spreading of the fires. Their hypothesis is that the towers collapsed ultimately due to the fires they suffered: As the fires burned, the buildings’ steel core columns buckled and shortened. This shifted more load to the buildings’ perimeter columns, which were already affected by the heat of the fires, and caused them to give way under the increased stress. Investigators have conducted a test with a reconstructed section of the WTC floor, and found that the original fireproofing was sufficient to meet the New York City building code. They say that had a typical office fire occurred in the towers, without the structural damage and the loss of some fireproofing caused by the plane impacts, it is likely the buildings would have remained standing. Lead investigator Dr. Shyam Sunder says, “The buildings performed as they should have in the airplane impact and extreme fires to which they were subjected. There is nothing there that stands out as abnormal.” NIST’s theories of why the WTC buildings collapsed conflict with an earlier investigation by FEMA, which claimed the collapse of the North Tower had begun in its core, rather than its perimeter columns (see May 1, 2002).

The National Institute of Standards and Technology (NIST), which is conducting an investigation into the WTC collapses on 9/11, releases three new reports. Investigators say that the Twin Towers would probably have remained standing if the fireproofing material that surrounded the buildings’ structural steel had not been stripped away when the planes hit. Their report states that “[t]he jet fuel, which ignited the fires, was mostly consumed within the first few minutes after impact. The fires that burned for almost the entire time that the buildings remained standing were due mainly to burning building contents and, to a lesser extent, aircraft contents, not jet fuel.” However, they claim, without the loss of fireproofing during the planes’ impacts, the heat from the fires would have been insufficient to cause the buildings to collapse. They say that although the architects had in 1964 tested the impact of a Boeing 707 airplane crashing into the 80th floor of one of the towers, they never envisioned the intense fires that ensued. NIST also reports that the time taken by survivors from the North Tower to descend a flight of stairs was about double the slowest evacuation speed estimated in a standard fire engineering text. They state: “approximately 87 percent of the WTC tower occupants, including more than 99 percent below the floors of impact, were able to evacuate successfully.” However, they say, if each tower had been full when they were hit, as many as 14,000 people could have died.

National Institute of Standards and Technology (NIST) releases a 12-page appendix to its final reports on the WTC collapses (see October 26, 2005) detailing tests it conducted on samples of the type of fireproofing used in the WTC. An earlier NIST report had concluded that loss of fireproofing was a major factor in the collapses (see April 5, 2005). The appendix was not included in earlier drafts of the report (see June 23, 2005) [National Institute of Standards and Technology, 6/23/2005 pdf file; National Institute of Standards & Technology, 9/2005, pp. 263-274 pdf file; National Institute of Standards and Technology, 9/2005, pp. 149] NIST conducted a series of fifteen tests. In the tests projectiles were fired at fireproofing mounted on 12 inch x 12 inch plates, and steel bars with a one inch diameter. The fireproofing used in the tests was Blazeshield DC/F, one of the two grades of fireproofing used on the impact floors. In thirteen of the tests the projectiles were buckshot, which was fired at the steel samples from a modified shotgun at a distance of 29.5 ft. The other two tests used steel bolts and hexagon nuts, fired with less velocity and at closer range. According to NIST, “The test results support the assumption that, within the debris field created by the aircraft impact into WTC 1 and WTC 2, the SFRM [i.e., fireproofing] used for thermal insulation of structural members was damaged and dislodged.” [National Institute of Standards & Technology, 9/2005, pp. 83, 263-274 pdf file]

The cockpit voice recorder tape from United 93, which crashed in Shanksville, Pennsylvania (see (10:06 a.m.) September 11, 2001), is played at the trial of Zacarias Moussaoui (see March 6-May 4, 2006) just before the prosecution rests its case. Translations are displayed on a screen along with information taken from the plane’s flight data recorder, such as speed, altitude, and steering yoke position. [Associated Press, 4/12/2006; London Times, 4/12/2006] The recording is sealed by the judge and a transcript is made available to the public. [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] This is a big media event and it receives lots of coverage. CNN, for example, calls it “an absolutely spellbinding, unforgettable day in court.” Many of the passages are unintelligible, but the recording seems to indicate that the hijackers murdered a flight attendant. [CNN, 4/12/2006; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006 pdf file] Some of the victims’ relatives previously heard the recording at a private meeting (see April 18, 2002).
