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.

Pete Zalewski.Pete Zalewski. [Source: NBC]Because the talkback button on Flight 11 has been activated, Boston Center air traffic controllers can hear a hijacker on board say to the passengers: “We have some planes. Just stay quiet and you’ll be OK. We are returning to the airport.” [Boston Globe, 11/23/2001; 9/11 Commission, 7/24/2004, pp. 19] Air traffic controller Pete Zalewski recognizes this as a foreign, Middle Eastern-sounding voice, but does not make out the specific words “we have some planes.” He responds, “Who’s trying to call me?” Seconds later, in the next transmission, the hijacker continues: “Nobody move. Everything will be OK. If you try to make any moves you’ll endanger yourself and the airplane. Just stay quiet.” [New York Times, 10/16/2001; 9/11 Commission, 6/17/2004; MSNBC, 9/9/2006] Bill Peacock, the FAA director of air traffic services, later claims, “We didn’t know where the transmission came from, what was said and who said it.” David Canoles, the FAA’s manager of air traffic evaluations and investigations, adds: “The broadcast wasn’t attributed to a flight. Nobody gave a flight number.” [Washington Times, 9/11/2002] Similarly, an early FAA report will state that both these transmissions came from “an unknown origin.” [Federal Aviation Administration, 9/17/2001 pdf file] Zalewski asks for an assistant to help listen to the transmissions coming from the plane, and puts its frequency on speakers so others at Boston Center can hear. Because Zalewski didn’t understand the initial hijacker communication from Flight 11, the manager of Boston Center instructs the center’s quality assurance specialist to “pull the tape” of the transmission, listen to it carefully, and then report back. They do this, and by about 9:03 a.m. a Boston manager will report having deciphered what was said in the first hijacker transmission (see 9:03 a.m. September 11, 2001). [9/11 Commission, 6/17/2004; MSNBC, 9/9/2006] Fellow Boston controller Don Jeffroy also hears the tape of the hijacker transmissions, though he doesn’t state at what time. He says: “I heard exactly what Pete [Zalewski] heard. And we had to actually listen to it a couple of times just to make sure that we were hearing what we heard.” [MSNBC, 9/11/2002] At some point, Ben Sliney, the national operations manager at the FAA’s Herndon Command Center, gets word of the “We have some planes” message, and later says the phrase haunts him all morning. American Airlines Executive Vice President for Operations Gerard Arpey is also informed of the “strange transmissions from Flight 11” at some point prior to when it crashes at 8:46 a.m. [USA Today, 8/12/2002] Boston Center will receive a third transmission from Flight 11 about ten minutes later (see (8:34 a.m.) September 11, 2001).

Flight controllers hear a hijacker on Flight 11 say to the passengers: “Nobody move, please, we are going back to the airport. Don’t try to make any stupid moves.” [New York Times, 10/16/2001; Guardian, 10/17/2001; Boston Globe, 11/23/2001; 9/11 Commission, 6/17/2004] This is the third hijacker transmission from Flight 11 heard by Boston Center. Following the previous two transmissions, controller Pete Zalewski had put the plane’s frequency on speakers so that others at the center could hear (see 8:24 a.m. September 11, 2001). This is therefore the first time some of them hear the hijacker’s voice. One controller says out loud, “That is really scary.” [MSNBC, 9/11/2002]

Flight controllers ask the United Airlines Flight 175 pilots to look for a lost American Airlines plane 10 miles to the south—a reference to Flight 11. They respond that they can see it. They are told to keep away from it. [Guardian, 10/17/2001; Boston Globe, 11/23/2001; 9/11 Commission, 6/17/2004] Apparently, Flight 175 is not told Flight 11 has been hijacked. Flight 175 itself is hijacked a few minutes later (see 8:41 a.m.-8:42 a.m. September 11, 2001).

NORAD fails to notify the National Military Command Center (NMCC) at the Pentagon that aircraft have been hijacked before the NMCC initiates a significant event conference in response to the terrorist attacks. [9/11 Commission, 6/9/2004] NORAD’s Northeast Air Defense Sector (NEADS) was alerted to the first hijacking, of Flight 11, at 8:37 a.m. (see (8:37 a.m.) September 11, 2001) and it is alerted to the second hijacking, of Flight 175, at 9:03 a.m. (see (9:03 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20, 23] And yet, according to an after-action report produced by the NMCC, NORAD does not contact the NMCC to alert it to these incidents before the significant event conference commences, at 9:29 a.m. (see 9:29 a.m.-9:34 a.m. September 11, 2001). [9/11 Commission, 6/9/2004]
NORAD Does Not Provide Information to Deputy Director - Captain Charles Leidig, the acting deputy director for operations in the NMCC, will later say that he “does not remember getting a lot of information from NORAD” before the significant event conference begins. [9/11 Commission, 4/29/2004 pdf file] NMCC personnel apparently learn that an aircraft has been hijacked when an officer in the center calls the FAA at 9:00 a.m. (see 9:00 a.m. September 11, 2001). [9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 5/5/2004; 9/11 Commission, 7/24/2004, pp. 35]
NORAD First Mentions a Hijacking at 9:33 a.m. - NORAD will apparently talk to the NMCC about a hijacking for the first time at around 9:33 a.m., when its representative on the significant event conference states that they “concur that [a] hijacked aircraft is still airborne [and] heading towards Washington, DC.” [US Department of Defense, 9/11/2001; US Department of Defense, 9/11/2001 pdf file] (They will presumably be referring to the incorrect information that Flight 11 is still in the air after it has crashed into the World Trade Center (see 9:21 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 26] )
NORAD Does Not Request a Conference - Additionally, according to the NMCC’s after-action report, NORAD “does not request any conference at [National Command Authority] level” prior to the commencement of the significant event conference. [9/11 Commission, 6/9/2004] The significant event conference is actually initiated by Leidig. The NMCC has an important role to play in an emergency like the current crisis. Its job under these circumstances “is to gather the relevant parties and establish the chain of command between the National Command Authority—the president and the secretary of defense—and those who need to carry out their orders,” according to the 9/11 Commission Report. [9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 37] It is also “the focal point within [the] Department of Defense for providing assistance” when there is a hijacking in US airspace, according to a recent military instruction (see June 1, 2001).

Flight 175 passes from the airspace of the FAA’s Boston Center to the airspace of the New York Center, which is in Ronkonkoma, New York. [9/11 Commission, 8/26/2004, pp. 20] New York Center air traffic controller Dave Bottiglia takes over monitoring the flight from Boston Center controller John Hartling (see (8:34 a.m.) September 11, 2001). Flight 175 waits nearly 45 seconds to check in with Bottiglia. According to author Lynn Spencer, this is “rather long, and Bottiglia is just about to call the plane.” But then Captain Victor Saracini, the pilot of Flight 175, makes radio contact, saying, “New York, United 175 heavy.” [Gregor, 12/21/2001 pdf file; Spencer, 2008, pp. 36]

Victor Saracini.Victor Saracini. [Source: Family photo]Just after Flight 175 enters the airspace of the FAA’s New York Center (see 8:40 a.m. September 11, 2001), its pilot reports to the air traffic controller now managing the flight a suspicious transmission he had heard on departing Boston’s Logan Airport. The pilot, Captain Victor Saracini, tells the controller, Dave Bottiglia: “We figured we’d wait to go to your center. Ah, we heard a suspicious transmission on our departure out of Boston, ah, with someone, ah, it sounded like someone keyed the mikes and said, ah, ‘Everyone, ah, stay in your seats.’” [New York Times, 10/16/2001; 9/11 Commission, 7/24/2004, pp. 21; Spencer, 2008, pp. 36] Saracini is presumably referring to one of the three radio transmissions from Flight 11, where the voice of a hijacker could be heard (see 8:24 a.m. September 11, 2001 and (8:34 a.m.) September 11, 2001). However, none of these had included the hijacker telling people to stay in their seats, as Saracini describes, although the second and third transmissions included the hijacker telling the passengers, “Nobody move.” [9/11 Commission, 7/24/2004, pp. 19] Bottiglia responds: “Oh, okay. I’ll pass that along.” Referring to the fact that this was the end of the transmission he heard, Saracini adds, “It cut out,” and then asks Bottiglia, “Did you copy that?” [Gregor, 12/21/2001 pdf file; Spencer, 2008, pp. 36-37] This is the last radio transmission from Flight 175. The 9/11 Commission will conclude that the plane is hijacked within the next four minutes (see (Between 8:42 a.m. and 8:46 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 20] According to author Lynn Spencer, since controllers are only given information on a need-to-know basis, Bottiglia was unaware there were problems with Flight 11, which has not yet entered his airspace. He touches his computer screen to connect to the hotline for his sector controller, and then reports: “UAL 175 just came on my frequency and he said he heard a suspicious transmission when they were leaving Boston. ‘Everybody stay in your seats’—that’s what he heard… just to let you know.” [New York Times, 10/16/2001; Spencer, 2008, pp. 36-37]

According to the 9/11 Commission, Flight 175 is hijacked some time between 8:42—when its flight crew make their last communication with the ground—and 8:46. The Commission describes that the hijackers “used knives (as reported by two passengers and a flight attendant), Mace (reported by one passenger), and the threat of a bomb (reported by the same passenger). They stabbed members of the flight crew (reported by a flight attendant and one passenger). Both pilots had been killed (reported by one flight attendant).” These witness accounts come from phone calls made from the rear of the plane, from passengers who’d been assigned seats in the front or middle of the cabin. According to the Commission, this is “a sign that passengers and perhaps crew [are] moved to the back of the aircraft.” [9/11 Commission, 7/24/2004, pp. 7; 9/11 Commission, 8/26/2004, pp. 20] An employee at the FAA’s Boston Center later says the hijacking occurs when Flight 175 is above Albany, NY, about 140 miles north of New York City. [Telegraph (Nashua), 9/12/2001; Associated Press, 9/13/2001] The first “operational evidence” that something is wrong is at 8:47, when Flight 175’s transponder code changes twice within a minute (see 8:46 a.m.-8:47 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 7]

After 9/11, NORAD and other sources will claim that NORAD’s Northeast Air Defense Sector (NEADS) is notified at this time that Flight 175 has been hijacked. [Washington Post, 9/12/2001; CNN, 9/17/2001; North American Aerospace Defense Command, 9/18/2001; Associated Press, 8/19/2002; Newsday, 9/10/2002] However, the FAA’s New York Center, which is handling Flight 175, first alerts its military liaison about the hijacking at around 9:01 (see 9:01 a.m.-9:02 a.m. September 11, 2001). In addition, according to the 9/11 Commission, NEADS is not informed until two minutes later (see (9:03 a.m.) September 11, 2001). [9/11 Commission, 6/17/2004] According to the Commission, the first “operational evidence” that there is something wrong on Flight 175 is not until 8:47, when its transponder code changes (see 8:46 a.m.-8:47 a.m. September 11, 2001), and it is not until 8:53 that the air traffic controller handling it concludes that Flight 175 may be hijacked (see 8:51 a.m.-8:53 a.m. September 11, 2001).

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]

[Source: NBC News]After being focused on Flight 11, Dave Bottiglia, an air traffic controller at the FAA’s New York Center, first notices problems with Flight 175. [MSNBC, 9/11/2002; 9/11 Commission, 7/24/2004, pp. 21] Both Flight 11 and Flight 175 have been in the airspace that Bottiglia is responsible for monitoring (see 8:40 a.m. September 11, 2001 and (8:42 a.m.-8:46 a.m.) September 11, 2001). Bottiglia has just watched Flight 11’s radar blip disappear, which means the plane has dipped below his radar’s coverage area, so is below 2,000 feet. But he does not yet realize it has crashed. He says aloud, “Well, we know he’s not high altitude anymore.” [MSNBC, 9/11/2002; Spencer, 2008, pp. 37] Around this time, Flight 175’s transponder changes twice in the space of a minute (see 8:46 a.m.-8:47 a.m. September 11, 2001).
Conflicting Accounts - According to MSNBC, “within seconds” of losing Flight 11’s blip, “Bottiglia has another unexpected problem.” While looking for Flight 11, he realizes that Flight 175 is also missing, and “instinctively… knows the two [planes] are somehow related.” He asks another controller to take over all of his other planes. [MSNBC, 9/11/2002] But according to the 9/11 Commission’s account, Bottiglia is still trying to locate Flight 11 after it crashes, and so it is not until 8:51 a.m. that he notices the problem with Flight 175 (see 8:51 a.m.-8:53 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 21]
'An Intruder over Allentown' - Around the time Flight 175 changes its transponder code, air traffic controller Curt Applegate, who is sitting at the radar bank next to Bottiglia’s, sees a blip that might be the missing Flight 11. He shouts out: “Look. There’s an intruder over Allentown.” According to the Washington Post, “In air traffic jargon, an ‘intruder’ is a plane with an operating transponder that has entered restricted airspace without permission.” In fact, it is the missing Flight 175. [Washington Post, 9/17/2001; MSNBC, 9/11/2002] However, these accounts make no mention of NORAD being notified about the problems with Flight 175 at this time. But according to a NORAD timeline released shortly after 9/11, NORAD’s Northeast Air Defense Sector (NEADS) was alerted about Flight 175 by the FAA several minutes earlier, at 8:43 a.m. (see 8:43 a.m. September 11, 2001).

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).

He assumes that Flight 175, which he is tracking on his radar screen, is also headed into the WTC. He will recall: “Probably one of the most difficult moments of my life was the 11 minutes from the point I watched that aircraft, when we first lost communications until the point that aircraft hit the World Trade Center. For those 11 minutes, I knew, we knew, what was going to happen, and that was difficult.” [CNN, 8/12/2002] Yet, according to the 9/11 Commission, the New York Center will not notify NORAD’s Northeast Air Defense Sector (NEADS) about Flight 175 until around the time it crashes, at 9:03 a.m. (see (9:03 a.m.) September 11, 2001).

Adam AriasAdam Arias [Source: US Air Force]Major Don Arias, the public affairs officer for NORAD, has just learned of the first WTC crash from television and a phone call from NEADS (see (8:38 a.m.-8:52 a.m.) September 11, 2001). Alarmed because his younger brother works at the WTC, he calls him immediately. Adam Arias works for an investment company on the 84th floor of the South Tower. According to some accounts, Don Arias tells his brother that the aircraft that crashed into the North Tower was likely a hijacked plane that he has been informed of, and orders him to “Get out of there. Go home.” [Florida State Times, 11/2001; Newhouse News Service, 1/25/2002; Airman, 9/2002] But according to Newsday, Don Arias tells his brother he has heard there is “another hijacked airliner and might be another attack.” [Newsday, 10/30/2001] This would be consistent with an early NORAD timeline, which had the agency receiving notification of the second hijacking at 8:43 a.m. (see 8:43 a.m. September 11, 2001). However, later accounts, including the 9/11 Commission Report, will claim NORAD only hears of it around the time the plane hits the South Tower (see (9:03 a.m.) September 11, 2001). Adam Arias reacts to his brother’s call with urgency, going around the floor exhorting people to leave, and physically throwing one woman out of her office. Several survivors will later credit him with saving their lives. [Newhouse News Service, 1/25/2002; Airman, 9/2002; Filson, 2003, pp. 124] Adam Arias will be killed when the South Tower collapses.

The head air traffic controller at the FAA’s New York Center notifies a manager at the facility that she believes Flight 175 has been hijacked. The manager tries to notify regional managers about this, but cannot reach them because they are discussing the hijacking of Flight 11 and refuse to be disturbed. However, even though the controller managing Flight 175 said, “we may have a hijack” at 8:53 a.m. (see 8:51 a.m.-8:53 a.m. September 11, 2001), the 9/11 Commission will conclude that NORAD’s Northeast Air Defense Sector (NEADS) is not notified about the aircraft until 9:03 a.m. (see (9:03 a.m.) September 11, 2001).

About a half-dozen air traffic controllers at the FAA’s New York Center in Ronkonkoma, NY, watch Flight 175 on the radar screen in its final minutes, as it approaches Manhattan. [National Transportation Safety Board, 2/19/2002 pdf file; Vanity Fair, 8/1/2006] Flight 175 is marked on the screen with the letter “I” for “intruder.” Initially, those at the center think it might be heading for Newark Airport, maybe for an emergency landing there. But controller Jim Bohleber says, “No, he’s too fast and low, he’ll never make Newark.” [Newsday, 9/10/2002] The controllers start speculating what Flight 175 is aiming for, with one of them guessing the Statue of Liberty. [Vanity Fair, 8/1/2006] They are astonished at the extraordinary rate at which it is descending (see (8:58 a.m.-9:03 a.m.) September 11, 2001).

The military liaison at the FAA’s New York Center is reportedly told that Flight 175 has been hijacked. The information is passed on to the liaison by New York Center manager Peter Mulligan. In an apparent reference to the hijacking on a phone bridge with other air traffic control facilities, Mulligan first says the situation is escalating (see (9:01 a.m.) September 11, 2001) and adds, “Just get me somebody who has the authority to get military in the air now.” Mulligan then drops out of the teleconference for a short while, but returns and says: “It’s OK. I’ve got it taken care of over here. I got… my military guy. We got some interceptors in the air.” [Federal Aviation Administration, 10/14/2003, pp. 15-17 pdf file] According to the 9/11 Commission Report, Mulligan says this between 9:01 and 9:02. [9/11 Commission, 7/24/2004, pp. 22] A person at the New York Center then calls NEADS at 9:03 (see (9:03 a.m.) September 11, 2001).

Moments before Flight 175 crashes into the World Trade Center, Colin Scoggins, the military liaison at the FAA’s Boston Center, calls NORAD’s Northeast Air Defense Sector (NEADS) to notify it that there is a second hijacked aircraft over the US. Scoggins learned of the second hijacking on the FAA headquarters’ hijack teleconference (see (Shortly Before 9:02 a.m.) September 11, 2001) and senses that he should call NEADS with this latest information. According to author Lynn Spencer, Scoggins “imagines that he must be one of dozens of FAA facilities flooding [NEADS] with phone calls. What he doesn’t know is that his is in fact the only one giving them information about the flights this morning, other than the coverage on CNN.” [Spencer, 2008, pp. 82] However, the 9/11 Commission will say that NEADS also learns of the second hijacking around this time from the FAA’s New York Center, stating, “The first indication that the NORAD air defenders had of the second hijacked aircraft, United 175, came in a phone call from New York Center to NEADS at 9:03” (see (9:03 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 23] Just after Scoggins reports the second hijacking to NEADS, those on the NEADS operations floor see the live television coverage of Flight 175 hitting the South Tower on a screen at the front of the room. [Spencer, 2008, pp. 82] Apparently, Scoggins’s phone call continues for several minutes: According to the 9/11 Commission, “Between 9:04 a.m. and 9:07 a.m., the NEADS identification technicians were on the phone with FAA Boston Center seeking further information on Flight 175 when Boston Center confirmed a second crash at the World Trade Center.” [9/11 Commission, 8/26/2004, pp. 24]

The 9/11 Commission will later conclude that the FAA’s New York Center tells NORAD’s Northeast Air Defense Sector (NEADS) that Flight 175 has been hijacked at this time. The Commission will refer to this as “the first indication that the NORAD air defenders had of the second hijacked aircraft.” The notification is apparently received from the military liaison at the New York Center (see 9:01 a.m.-9:02 a.m. September 11, 2001).

NEADS Technician Announces 'Second Possible Hijack' - Tape recordings of the NEADS operations floor will reveal ID tech Stacia Rountree answering the call from the New York Center, and saying out loud, “They have a second possible hijack!” [Vanity Fair, 8/1/2006] Colonel Robert Marr, the NEADS battle commander, will claim he first learns that an aircraft other than Flight 11 has been hijacked when he sees Flight 175 crash into the World Trade Center on television. [Aviation Week and Space Technology, 6/3/2002] Lieutenant Colonel Dawne Deskins will claim that when she sees Flight 175 hitting the South Tower on television, “we didn’t even know there was a second hijack.” [Filson, 2003, pp. 59]
Conflicting Accounts - However, these accounts contradict NORAD’s claim that it makes shortly after 9/11 that NEADS was first notified about Flight 175 at 8:43 a.m. (see 8:43 a.m. September 11, 2001). [North American Aerospace Defense Command, 9/18/2001] Additionally, as Flight 175 crashes into the WTC, Canadian Captain Mike Jellinek, who is working at NORAD’s Cheyenne Mountain, Colorado operations center, is on the phone with NEADS. He sees the crash live on television and asks NEADS, “Was that the hijacked aircraft you were dealing with?” The reply is yes. (However, it is unclear whether Jellinek is referring to Flight 175 or to the smoke coming from the crash of Flight 11.) [Toronto Star, 12/9/2001] If the 9/11 Commission’s account is correct, several questions remain unanswered. Flight 175 lost radio contact at 8:42 a.m. (see 8:41 a.m.-8:42 a.m. September 11, 2001) and changed transponder signals at 8:47 a.m. (see 8:46 a.m.-8:47 a.m. September 11, 2001); an air traffic controller declared it possibly hijacked sometime between 8:46 a.m. and 8:53 a.m. (see (Shortly After 8:46 a.m.) September 11, 2001); and an air traffic control manager called it hijacked at 8:55 a.m.(see (8:55 a.m.) September 11, 2001). The Commission will not explain why the New York Center waits 10 to 16 minutes before warning NEADS that Flight 175 is possibly hijacked. [9/11 Commission, 6/17/2004]

There is considerable confusion on the operations floor over whether the plane seen on TV is the hijacking they have just been informed of. Tape recordings capture NEADS personnel in the background trying to make sense of things: “Is this explosion part of that that we’re lookin’ at now on TV?“… “And there’s a possible second hijack also—a United Airlines“… “Two planes?” Someone comments, “I think this is a damn input, to be honest.” [Vanity Fair, 8/1/2006] Another person replies, “Then this is a damned messed-up input!” [Spencer, 2008, pp. 84] “Input” refers to a simulations input, as part of a training exercise.

Rich Miles, the manager of United Airlines’ System Operations Control center outside Chicago, tries to initiate the “lockout” procedure for Flight 93, which would acknowledge an emergency on the flight and safeguard information about it, but he is unable to do so. At some time between 9:45 a.m. and 9:50 a.m., the United Airlines maintenance facility in San Francisco contacted Miles about a call it had just received from an attendant on Flight 93, reporting that her plane had been hijacked (see 9:35 a.m. September 11, 2001). In response, Miles attempts to initiate a lockout of Flight 93. Lockout is a standard procedure for airlines in safety and security incidents, which isolates information about a flight so the case can be managed by the airline’s top leadership, and protects the identities of the passengers and crew. But Miles is unable activate this procedure. According to the 9/11 Commission, this is because United Airlines has already conducted a lockout of Flight 175 (see (9:21 a.m.) September 11, 2001), and its computer system is not presently set up to deal simultaneously with two such procedures.

The Federal Aviation Administration (FAA) produces a chronology of the events of September 11, which it uses when it briefs the White House today, but the document fails to mention when NORAD’s Northeast Air Defense Sector (NEADS) was alerted to two of the hijacked planes. The FAA’s chronology, titled “Summary of Air Traffic Hijack Events,” incorporates “information contained in the NEADS logs, which had been forwarded, and on transcripts obtained from the FAA’s Cleveland Center, among others,” according to John Farmer, the senior counsel to the 9/11 Commission.
Document Includes Notification Times for First Two Hijacked Flights - The chronology refers “accurately to the times shown in NEADS logs for the initial notifications from FAA about the hijacking of American 11 and the possible hijacking of United 175,” according to the 9/11 Commission. It gives 8:40 a.m. as the time at which the FAA alerted NEADS to Flight 11, the first plane to be hijacked (see (8:37 a.m.) September 11, 2001), and 9:05 a.m. as the time when the FAA alerted NEADS to Flight 175, the second plane to be hijacked (see (9:03 a.m.) September 11, 2001). However, it makes no mention of when the FAA alerted NEADS to Flight 77 and Flight 93, the third and fourth planes to be hijacked. The FAA’s omission of these two notification times is “suspicious,” according to the 9/11 Commission, “because these are the two flights where FAA’s notification to NEADS was significantly delayed.”
Document Omits Notification Times for Flights 77 and 93 - The chronology, as Farmer will later point out, “makes no mention… of the notification to NEADS at 9:33 that American 77 was ‘lost’ (see 9:34 a.m. September 11, 2001) or of the notification to NEADS at 9:34 of an unidentified large plane six miles southwest of the White House (see 9:36 a.m. September 11, 2001), both of which are in the NEADS logs that the FAA reviewed” when it was putting together the timeline. It also fails to mention the call made by the FAA’s Cleveland Center to NEADS in which, at 10:07 a.m., the caller alerted NEADS to Flight 93 and said there was a “bomb on board” the plane (see 10:05 a.m.-10:08 a.m. September 11, 2001), even though this information was also “duly noted in the NEADS logs” that the FAA has reviewed.
Chronology Omits Other Key Information - The chronology, Farmer will write, reflects “a time at which the FAA was notified that the Otis [Air National Guard Base] fighters were scrambled” in response to the hijacking of Flight 11 (see 8:46 a.m. September 11, 2001), but it gives “no account of the scramble of the fighters from Langley Air Force Base” (see 9:24 a.m. September 11, 2001). It also fails to mention the report that NEADS received after Flight 11 crashed, in which it was incorrectly told the plane was still airborne and heading toward Washington, DC (see 9:21 a.m. September 11, 2001). Despite lacking information about the times when the FAA alerted NEADS to Flights 77 and 93, the FAA’s chronology is one of the documents used to brief the White House about the 9/11 attacks today (see September 17, 2001).
Investigators Were Told to Determine Exact Notification Times - The chronology is the product of investigations that began promptly in response to the 9/11 attacks. According to senior FAA officials, FAA Administrator Jane Garvey and Deputy Administrator Monte Belger “instructed a group of FAA employees (an ‘after-action group’) to reconstruct the events of 9/11.” This group, according to the 9/11 Commission, “began its work immediately after 9/11 and reviewed tape recordings, transcripts, handwritten notes, logs, and other documents in an effort to create an FAA chronology of events.” The group, according to one witness, “was specifically asked to determine exactly when the FAA notified the military that each of the four planes had been hijacked,” and “[s]everal people worked on determining correct times for FAA notifications to the military.” [Federal Aviation Administration, 9/17/2001 pdf file; 9/11 Commission, 7/29/2004; Farmer, 2009, pp. 245-247] NORAD will release a timeline of the events of September 11 and its response to the attacks a day after the FAA chronology is published (see September 18, 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).
