Douglas Karpiloff.Douglas Karpiloff. [Source: Port Authority of New York and New Jersey]A command center for the Port Authority of New York and New Jersey, located in the North Tower of the World Trade Center, is upgraded to make it more secure, and the improvements will reportedly save the lives of people in the command center when the nearby South Tower collapses on September 11. [Newsday, 9/12/2001; Civil Air Patrol News, 1/2002; Newsday, 1/23/2002] The Port Authority’s Security Command Center (SCC) is on the 22nd floor of the North Tower. [9/11 Commission, 5/18/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 294] Newsday will report, on the day after 9/11, that officials had “recently” increased security at the WTC “by installing bulletproof windows and fireproof doors in the 22nd-floor computer command center.” [Newsday, 9/12/2001] According to George Tabeek, the Port Authority’s security manager for the WTC, by September 11, the WTC in fact has “bulletproof window glass in most areas.” [FDU Magazine, 6/2008] The installation of the bulletproof windows—and presumably, also, the fireproof doors—in the SCC is made at the request of Douglas Karpiloff, the Port Authority’s director of security and life safety for the WTC. [Newsday, 1/23/2002]
Upgrades Intended to Protect against 'Aerial Attacks' - According to Hermina Jones, a security guard at the WTC, the upgrades to the SCC are intended “to secure the towers against aerial attacks.” [Newsday, 9/12/2001] Tabeek will later recall, “We had planned for the possibility of a small airplane—a corporate jet, maybe—crashing into one of the [WTC] buildings by accident,” although it is unclear if this comment is made in reference to the installation of bulletproof windows at the WTC. [FDU Magazine, 6/2008]
Security Improvements Save Lives on September 11 - Some people will credit the upgrades to the SCC with saving their lives on September 11. Tabeek will be in the SCC that day when the first of the Twin Towers—the South Tower—collapses (see 9:59 a.m. September 11, 2001). When that happens, according to Tabeek, the “impact of the explosion peeled off the outer skin of [the North Tower], shattering the thick double-paned windows [of the SCC] in the process.” Tabeek will say, however, that the “inner layer of laminated bulletproof glass put in months earlier… withstood the blast and undoubtedly saved his life and those of the others with him.” Victor Guarnera, the chief technical adviser and manager of security systems for the World Trade Department, who is also in the SCC at that time, will describe what happens when the collapse occurs, saying, “The outer windows [of the SCC] exploded, either from impact [of debris from the South Tower] or differential pressure, but the inner window wall of high-tempered bomb and bullet-resistant glass we had installed a few months before held fast.” Guarnera will comment that the bulletproof windows “were responsible for our survival up to that point.” [Civil Air Patrol News, 1/2002; Newsday, 1/23/2002]

The hole caused by the Flight 11 crash.The hole caused by the Flight 11 crash. [Source: Reuters]Flight 11 slams into the WTC North Tower (Building 1). Hijackers Mohamed Atta Waleed Alshehri, Wail Alshehri, Abdulaziz Alomari, and Satam Al Suqami presumably are killed instantly, and many more in the tower will die over the next few hours. Seismic records pinpoint the crash at 26 seconds after 8:46 a.m. [CNN, 9/12/2001; New York Times, 9/12/2001; 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; USA Today, 8/13/2002; Associated Press, 8/21/2002; Newsday, 9/10/2002] The NIST report states the crash time to be 8:46:30. [National Institute of Standards and Technology, 9/2005, pp. 19] The 9/11 Commission Report states the crash time to be 8:46:40. [9/11 Commission, 7/24/2004, pp. 7] Investigators believe the plane still has about 10,000 gallons of fuel (see 8:57 a.m. September 11, 2001). [New York Times, 5/26/2002] The plane strikes the 93rd through 99th floors in the 110-story building. No one above the crash line survives; approximately 1,360 people die. Below the crash line, approximately 72 die and more than 4,000 survive. Both towers are slightly less than half full at the time of the attack, with between 5,000 to 7,000 people in each tower. This number is lower than expected. Many office workers have not yet shown up to work, and tourists to the observation deck opening at 9:30 A.M. have yet to arrive. [USA Today, 12/20/2001; National Institute of Standards and Technology, 9/2005, pp. 20-22] The impact severs some columns on the north side of the North Tower. Each tower 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 weighs 283,600 lb and is traveling at an estimated speed of around 430 mph (see October 2002-October 2005), severs 35 of the building’s 236 perimeter columns and damages another two. The damage to the South Tower’s perimeter will be similar (see 9:03 a.m. September 11, 2001). [National Institute of Standards and Technology, 9/2005, pp. 5-9, 20, 22] The perimeter columns bear about half of the tower’s weight, so this damage reduces its ability to bear gravity loads by about 7.5 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 have damaged the core even after crashing through the exterior wall. According to the National Institute of Standards and Technology (NIST): “Moving at 500 mph, an engine broke any exterior column it hit. If the engine missed the floor slab, the majority of the engine core remained intact and had enough residual momentum to sever a core column upon direct impact.” [National Institute of Standards and Technology, 9/2005, pp. 107] According to NIST’s base case computer model, three of the core columns are severed and another ten suffer some damage. [National Institute of Standards & Technology, 9/2005, pp. 189 pdf file] If this is accurate, it means that the impact damage to the core reduces the Tower’s strength by another approximately 7.5 percent, meaning that the building loses about 15 percent of its strength in total. This damage will be cited after 9/11 by NIST and others researchers as an event contributing to the building’s collapse (see October 23, 2002 and October 19, 2004). In addition, some of the fireproofing on the steel columns and trusses may be dislodged. The original fireproofing on the fire floors was mostly Blazeshield DC/F, but some of the fireproofing on the flooring has recently been upgraded to Blazeshield II, which is about 20 percent denser and 20 percent more adhesive. [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 NIST will estimate the damage to it using a computer model. Its severe case model (see (October 2002-October 2005)) will predict that 43 of the 47 core columns are stripped of their fireproofing on one or more floors and that fireproofing is stripped from trusses covering 60,000 ft2 of floor area, the equivalent of about one and a half 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. 23] According to NIST, more fireproofing is stripped from the South Tower (see 9:03 a.m. September 11, 2001).

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.

[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).

Mike Dabney.Mike Dabney. [Source: FEMA]Personnel at the Federal Emergency Management Agency (FEMA) Region II office at 26 Federal Plaza in New York are unable to communicate with the city’s emergency command center in World Trade Center Building 7 and so Richard Ohlsen, one of the office’s employees, is sent to the WTC site to liaise with officials there. Personnel in the FEMA office felt their building shake when the first hijacked plane crashed into the WTC, at 8:46 a.m. (see 8:46 a.m. September 11, 2001), but were initially unclear about what had happened. They were able, however, to see the second crash, at 9:03 a.m. (see 9:03 a.m. September 11, 2001), through the windows. Apparently after that crash occurs, “communications almost instantly became a problem and compromised the ability of the Regional Operations Center [i.e. the office at 26 Federal Plaza] to operate,” Ohlsen will later recall. In particular, personnel there are unable to communicate with the city’s Office of Emergency Management (OEM), which has its emergency command center on the 23rd floor of WTC 7. Mike Dabney, the senior FEMA manager in the office, therefore instructs Ohlsen to go to WTC 7, which is within walking distance, and act as an on-site liaison with the OEM there. However, Ohlsen’s departure is delayed because his colleagues are unable to find a working radio or a satellite phone he can take with him. He consequently only heads out at around 9:59 a.m., when the South Tower of the WTC collapses (see 9:59 a.m. September 11, 2001). He will change his plans following the collapse and, instead of heading to WTC 7, go to the command post at the headquarters of the New York Police Department (see After 9:59 a.m. September 11, 2001).

A man who is on the 105th floor of the South Tower calls emergency 9-1-1 to report that floors below his location, “in the 90-something floor,” have collapsed. The 9-1-1 operator types a record of this call into the Special Police Radio Inquiry Network (SPRINT) data link, which will be passed on to the New York fire department’s Emergency Medical Service (EMS). It isn’t known when the call is made exactly, but the EMS Dispatch computer apparently receives the call record at this time. However, because it is classified as a “supplement message,” it is not yet read by anyone. The police dispatcher dealing with the area around the WTC also receives the call record, but misinterprets it as meaning that the floor the person is on has collapsed. EMS dispatchers are dealing with an enormous volume of calls as well as performing many other tasks under extreme pressure during the crisis, so a report later concludes that the EMS operators didn’t have the time to review the information before the collapse of the South Tower at 9:59 (see 9:59 a.m. September 11, 2001), and the fire chiefs never received the information.

Joseph Morris.Joseph Morris. [Source: Publicity photo]Inspector Joseph Morris, a commanding officer with the Port Authority Police Department (PAPD), tells numerous PAPD officers to initially stay away from the Twin Towers after they arrive near the World Trade Center, thereby likely preventing many of them from being killed when the South Tower collapses. [Police, 9/1/2002; Law Officer, 8/16/2011] Morris was in his office at New York’s La Guardia Airport when he heard someone yell out that an aircraft had crashed into the WTC. After turning on the television and seeing the images of the burning North Tower, he gave the order for all his available officers to go to the WTC. “I initiated a mobilization of personnel following long-held department plans and procedures for response to the World Trade Center for aircraft disasters and high-rise fires,” he will later describe. Morris and 17 colleagues head out and arrive in the vicinity of the WTC “maybe six to seven minutes” before the South Tower collapses, Morris will estimate, which would be at around 9:52 a.m. to 9:53 a.m. About 40 to 50 PAPD officers are at the location at this time and Morris is the highest-ranking commander among them. [Urban Hazards Forum, 1/2002; 9/11 Commission, 11/10/2003; 9/11 Commission, 5/18/2004 pdf file]
Officers Are Told to Stay Away from the WTC - The PAPD officers with Morris are keen to rush into the Twin Towers and get involved with the rescue operation. Normally, they would go to the lobby of the North Tower in an emergency like the current one. Morris, though, tells them to stay back while he assesses the situation. The decision is made for the officers to “break up into groups of three or four, with a supervisor,” and “get [their] bunker gear on,” Morris will say. He instructs them “not to go anywhere until I came up with a plan.” [Urban Hazards Forum, 1/2002; Police, 9/1/2002; Law Officer, 8/16/2011]
Commander Thinks There May Be Few People Left to Rescue - Morris will say his caution about allowing PAPD officers into the Twin Towers at the current time is partly because he sees very few civilians coming his way up West Street and this leads him to question how many people are left at the WTC to be rescued. [9/11 Commission, 11/10/2003] Some other Port Authority employees, in addition to the PAPD officers, are at the same location as Morris and Morris tells them, too, to stay away from the WTC. “I informed them they should stay at that location until more information was gathered for responses,” he will say. [9/11 Commission, 5/18/2004 pdf file]
Commander's Decision Likely Saves Lives - Morris’s decision to keep PAPD officers away from the WTC will be credited with saving the lives of people who may have been killed when the South Tower collapsed, at 9:59 a.m. (see 9:59 a.m. September 11, 2001), if they had headed to the Twin Towers. Alan Reiss, director of the Port Authority’s World Trade Department, will say that in retrospect, he believes it “most certainly saved lives of at least some of those officers held back.” [9/11 Commission, 11/3/2003] Law Officer magazine will describe it as a decision “that proved to be a lifesaver for many.” [Law Officer, 8/16/2011] Police magazine will call it one of “a couple of key decisions” Morris makes “that saved his department even greater tragedy” today. [Police, 9/1/2002] A few minutes after arriving near the WTC, Morris will decide to head to the incident command post in the North Tower to meet with other professionals who are assembled there. He will be going toward it with Lieutenant Emiliano Sepulveda, a colleague of his, when the South Tower starts to come down. He will run north up West Street and then find protection inside the PAPD’s command bus. [9/11 Commission, 11/10/2003; 9/11 Commission, 5/18/2004 pdf file; Law Officer, 8/16/2011]

Members of New York Police Department’s elite Emergency Service Unit (ESU) are given an order that means they have to get out of the World Trade Center or delay entering it and consequently many of them will avoid being killed when the South Tower collapses, at 9:59 a.m. [Keegan and Davis, 2006, pp. 101-102; Appel, 2009, pp. 112-113] The ESU is a highly trained organization comprised of first response rescuers. [City of New York, 6/29/2002] Its members respond to situations that require the most specialized training, such as hostage taking and water rescue, and use the most advanced equipment. [Keegan and Davis, 2006, pp. 101]
Officers Are Ordered to Come Down from the WTC - Inspector Ronald Wasson, commanding officer of the ESU, earlier on divided his officers into four teams of five or six men and then sent two teams into each of the Twin Towers to assist the rescue operation. [New York Daily News, 11/11/2001] But now, ESU commanders give the order for the unit’s members to “go tactical.” This means the officers in the towers have to come out of the buildings and go to the unit’s SWAT (special weapons and tactics) vans; put on their BDU (battle dress uniform) suits, flak jackets, and Kevlar helmets; and arm themselves with heavy weapons and assault rifles.
Commander Thinks Terrorists Might Attack the First Responders - The decision to order ESU officers to go tactical is made by Wasson, according to a book by Lieutenant William Keegan of the Port Authority Police Department. [Keegan and Davis, 2006, pp. 101-102] Wasson is currently assembled with a number of other ESU officers outside the Twin Towers, at the corner of West and Vesey Streets. [Appel, 2009, pp. 68] He decides that ESU officers should go tactical due to his concern that armed terrorists might attack the first responders at the WTC. He is “worried that with all his personnel inside the buildings, he [has] no way to protect the cops, firefighters, or civilians from the kind of low-intensity warfare—snipers, automatic weapons, car bombs, hostage situations—he [is] sure [will] follow the attack,” Keegan will write. He believes it is the responsibility of the New York Fire Department to deal with the fires in the Twin Towers, while the Police Department should be preparing for what might happen next. Many ESU members will come out of the towers after receiving the order to go tactical, according to Keegan. [Keegan and Davis, 2006, pp. 101-102]
Order Is Given after an Officer Hears of the Pentagon Attack - However, according to author Anthea Appel, the order to go tactical is made by Sergeant Tom Sullivan, another ESU officer. Sullivan is currently at the corner of West and Vesey Streets along with Wasson, getting ready to take two teams into the WTC. At 9:56 a.m., after hearing over his radio about the attack on the Pentagon, which occurred at 9:37 a.m. (see 9:37 a.m. September 11, 2001), he exclaims, “Screw rescue!” He then pulls his men back and announces that all ESU teams will be “going in tactical,” according to Appel. “I want heavy vests, helmets, rifles, and machine guns,” he says. In response to his announcement, ESU officers start taking off their rescue gear and putting on combat gear. They take off their safety helmets and replace them with ballistic helmets. They take off their air tanks, unbuckle their Roco harnesses, and put on more body armor over their bulletproof vests. They also unlock their gun bins and take out shotguns, submachine guns, and assault rifles. Some officers grumble under their breath, annoyed at being held back. “They didn’t like wasting time fiddling around with equipment,” Appel will comment, “and this sudden switch interrupted their adrenaline momentum.” They will be in the middle of changing into their combat gear when the South Tower collapses (see 9:59 a.m. September 11, 2001). [Appel, 2009, pp. 112-113]
Order Is Wrong but Saves Lives - The order to go tactical will turn out to be mistaken as there are no attacks by armed terrorists on the first responders at the WTC. However, as a result of it being issued, numerous ESU members will be outside the Twin Towers instead of inside the buildings when the South Tower comes down and many of them will therefore avoid being killed in the collapse. While 14 ESU members will die in the WTC collapses, a far greater number will survive, Keegan will write, “because Wasson’s order pulled them out of the towers and saved their lives.” [Keegan and Davis, 2006, pp. 102] One ESU member, Detective Frank DeMasi, will conclude that Sullivan “definitely saved his life when he made that last-minute decision to switch from rescue to tactical mode,” according to Appel, since the delay while they changed into their combat gear “kept DeMasi and his teammates from walking into the South Tower before it collapsed.” [Appel, 2009, pp. 265-266]

James Nieckarz.James Nieckarz. [Source: Maryknoll Mission Archives]Police officers order members of the public to get away from the World Trade Center, telling them the Twin Towers are in danger of collapsing. Shanthy Nambiar, a reporter for BridgeNews in New York, is standing on Vesey Street, beneath Building 7 of the WTC. She hears someone shout, “You guys shouldn’t be in this area.” She will later recall, “Police officers ordered people to start fleeing the area, saying the towers were in danger of collapse.” She runs north one block and then sees the South Tower coming down (see 9:59 a.m. September 11, 2001). [Casey, 2001, pp. 156] Priest Father James Nieckarz is also standing outside Building 7 around this time. He will recall that a couple of police officers come along, shouting out to everyone on the street: “Everyone run to the north. The tower is shaking and may come down.” Nieckarz goes around Building 7 and then, as he is walking north, hears “a loud rumbling roar” behind him as the South Tower collapses. [Salon, 9/12/2001; United States Conference of Catholic Bishops, 9/2003, pp. 15] Why the police officers encountered by Nambiar and Nieckarz believe the Twin Towers are in danger of collapsing is unclear. Although a New York City Police Department (NYPD) helicopter has reported “large pieces” falling from the South Tower (see (9:49 a.m.) September 11, 2001), the 9/11 Commission Report will state, “Prior to 9:59, no NYPD helicopter pilot predicted that either tower would collapse.” [9/11 Commission, 7/24/2004, pp. 304]

[Source: Associated Press]The South Tower of the World Trade Center tilts to the southeast and then collapses.

[National Institute of Standards and Technology, 9/2005, pp. 87] The angle of the tilt will be disputed after 9/11 (see September-November 2005), as will the time it takes the towers to fall to the ground (see September 12, 2001-September 2005).

Jay Kopstein.Jay Kopstein. [Source: Jay Kopstein]Richard Ohlsen, an employee at the Federal Emergency Management Agency (FEMA) Region II office in Lower Manhattan, goes to the headquarters of the New York Police Department (NYPD), but is initially denied entry into the building and, once inside, experiences various difficulties as he tries to respond to the terrorist attacks. Following the second crash at the World Trade Center, the FEMA office was unable to communicate with Office of Emergency Management personnel in WTC Building 7 and so Ohlsen was told to go to WTC 7 to act as a liaison there (see (After 9:03 a.m.) September 11, 2001). As he was on his way out, though, the South Tower of the WTC collapsed (see 9:59 a.m. September 11, 2001).
FEMA Employee Is Denied Entry into the Police Headquarters - Consequently, instead of going to the WTC site, Ohlsen heads to the command center at NYPD headquarters, at One Police Plaza. When he arrives at NYPD headquarters, however, officers refuse to let him in because they do not recognize his FEMA identification as being official. Fortunately, Jay Kopstein, an inspector with the NYPD who happens to be passing by, recognizes him and takes him up to the command center.
Employee Lacks Priority Access to the Phone Network - Ohlsen’s problems continue, however, after he arrives there. Ohlsen does not have with him a special GETS (Government Emergency Telecommunications Service) phone card, which gives government and emergency workers priority to make phone calls during a crisis. Consequently, when he wants to reach FEMA headquarters in Washington, DC, he has to contact it through the normal collect call procedures, even though this is a national emergency. And when he does get through, he is told that responsibility for dealing with the attacks in New York has been transferred to FEMA’s Region I office in Massachusetts, as part of the agency’s standard continuity of operations procedures, and so all requests are meant to go through there.
Officials Refuse to Open an Equipment Cache - Ohlsen also runs into difficulty when he asks for an equipment cache that contains personal protective gear and search and rescue equipment for New York City’s urban search and rescue team to be opened. He is incredulous when, in light of the current situation, officials with the New York City Fire Department, which maintains the cache, refuse his request, supposedly because no one from the federal government has authorized the use of the equipment. Ohlsen apparently persists and eventually gets the cache opened, since he will later describe this setback as “the first problem he was able to resolve” after arriving at the command center.

Damage to the southwest corner of WTC 7.Damage to the southwest corner of WTC 7. [Source: Arquelio Galarza]World Trade Center Building 7 (WTC 7) suffers some damage, caused by debris from the collapse of the north WTC tower, according to later official reports. [Federal Emergency Management Agency, 5/1/2002, pp. 5-16; National Institute of Standards and Technology, 11/2008, pp. 16]
WTC 7 Undamaged by South Tower Collapse - WTC 7 is a 47-story office building located 370 feet north of the North Tower (WTC 1). In the final report of its investigation into WTC 7’s collapse, published in November 2008 (see November 20, 2008), the National Institute of Standards and Technology (NIST) will state that although a few windows on the lower floors of WTC 7’s south face were broken when the South Tower (WTC 2) collapsed at 9:59 a.m. (see 9:59 a.m. September 11, 2001), “None of the large pieces of debris from WTC 2 hit WTC 7, because of the large distance between the two buildings,” and there is “no evidence of structural damage to WTC 7” as a result of the South Tower’s collapse.
Debris Reportedly Damages Exterior Columns - However, when the North Tower collapses (see 10:28 a.m. September 11, 2001), some fragments of debris are “forcibly ejected” from it, and travel “distances up to hundreds of meters.” According to NIST, pieces of this debris “hit WTC 7, severing six columns on floors 7 through 17 on the south face and one column on the west face near the southwest corner.” NIST will add that the debris also causes “structural damage between floor 44 and the roof,” and breaks a large number of windows on WTC 7’s south face.
Building Core Undamaged - However, NIST will state, based on “photographic evidence, witness accounts, and engineering judgment, it is likely that the structural damage (steel and floor slabs) did not penetrate beyond the perimeter of the building core. At the southwest corner, the structural damage extended only about one-third of the distance from the exterior wall to the building core.” NIST will comment, “Compared to the airplane impact damage to the WTC towers, there was relatively little damage to the interior of WTC 7.” There is also “no superficial or structural damage” to WTC 7’s north and east faces. And the sprayed fire resistive material that has been applied to the building’s steel columns, girders, and beams is only damaged in the “immediate vicinity of the WTC 1 debris impact.” NIST will admit, however, that there are “uncertainties” in its accounting of the events leading up to the collapse of WTC 7, because “the remains of all the WTC buildings were disposed of before Congressional action and funding was available for [its] investigation [of the WTC collapses] to begin” (see Shortly After September 11, 2001 and September 12-October 2001). [National Institute of Standards and Technology, 8/21/2008; National Institute of Standards and Technology, 11/2008, pp. 15-16]
FEMA Describes WTC 7 Damage - According to an earlier report on the collapse of WTC 7, published by the Federal Emergency Management Agency (FEMA) in May 2002 (see May 1, 2002), at that time, the “extent and severity of the resulting damage to WTC 7” when the North Tower collapses “are currently unknown.” But based on “photographic evidence and eyewitness accounts,” it is “assumed that the south side of the building was damaged to some degree.” FEMA’s report will state: “It does not appear that the collapse of WTC 1 affected the roof, or the east, west, and north elevations of WTC 7 in any significant way. However, there was damage to the southwest corner of WTC 7 at approximately floors 8 to 20, 24, 25, and 39 to 46.” The report will add: “According to firefighters’ eyewitness accounts from outside of the building, approximately floors 8-18 were damaged to some degree. Other eyewitness accounts relate that there was additional damage to the south elevation.” [Federal Emergency Management Agency, 5/1/2002, pp. 5-16, 5-20]
Structural Damage Not Responsible for Collapse - WTC 7 will collapse at 5:20 p.m. this afternoon (see (5:20 p.m.) September 11, 2001). [National Institute of Standards and Technology, 8/21/2008] However, NIST will conclude that the structural damage the building suffers plays no role in causing it to come down. NIST will state, “Other than initiating the fires in WTC 7, the damage from the debris from WTC 1 had little effect on initiating the collapse of WTC 7.” [National Institute of Standards and Technology, 11/2008, pp. xxxvii] WTC 7 suffers fires on some floors, which are reportedly initiated by debris from the collapse of the North Tower (see (10:28 a.m.-5:20 p.m.) September 11, 2001). According to NIST, it is these fires, “rather than the structural damage that resulted from the impacts” of debris, which “initiated the building’s collapse.” [National Institute of Standards and Technology, 8/21/2008]

At around 8:00 p.m., Afghanistan time (11:30 a.m., New York time), Taliban leader Mullah Omar allegedly says, “Things have gone much further than expected.” This is according to what the New Yorker will describe as “Afghan intelligence sources” who monitor the call. (It is unclear what “Afghan intelligence sources” means, since the Taliban control nearly all of Afghanistan at this time, but it could be a reference to Northern Alliance forces; the CIA gave them equipment to monitor the Taliban (see Winter 1999-March 2000).) Omar’s comment takes place over an hour after one of the World Trade Center towers collapsed, which means thousands have been killed in the attacks, not hundreds (see 9:59 a.m. September 11, 2001). An Afghan intelligence official will later say: “They were expecting a reaction. But they thought it would be a Clinton-type reaction. They didn’t anticipate the kind of revenge that occurred.” [New Yorker, 6/10/2002] The “Clinton-type reaction” presumably is a reference to the August 1998 missile strikes on Sudan and Afghanistan during the Clinton administration (see August 20, 1998).

Following the attacks, there is no agreement on the speed with which the Twin Towers of the World Trade Center collapsed on 9/11 (see 9:59 a.m. September 11, 2001 and 10:28 a.m. September 11, 2001). The 9/11 Commission says that the South Tower collapsed in “ten seconds” and the National Institute of Standards and Technology says that tops of the buildings came down “essentially in free fall.” [9/11 Commission, 7/24/2004, pp. 305; National Institute of Standards and Technology, 9/2005, pp. 146] In the dispute over the reason for the WTC’s collapse after 9/11, it is claimed that, if the towers fell in ten seconds, then this is evidence they were destroyed by explosives. For example, David Ray Griffin, a theologian and outspoken critic of commission’s report, writes, “For a 1,300-foot building, however, ten seconds is almost free-fall speed. But if each floor produced just a little resistance, so that breaking through each one took half a second, the collapse of all those floors—80 or 95 of them—would have taken 40 to 47 seconds. Can we really believe that the upper part of the buildings encountered virtually no resistance from the lower part?” [Griffin, 2004, pp. 16] But according to Canadian scientist Frank Greening, who studies the Twin Towers’ collapse, the freefall time would be about 9.6 seconds, and he calculates that it takes longer for the buildings to fall—twelve to thirteen and a half seconds—and states this does not indicate that explosives were used.

Both towers of the World Trade Center tilted to one side before beginning to fall on 9/11 (see 9:59 a.m. September 11, 2001 and 10:28 a.m. September 11, 2001). The National Institute of Standards and Technology, which investigated the collapses (see August 21, 2002), states that the South Tower, which was hit on its south side, tilted about 7-8 degrees to the east and 3-4 degrees to the south, and the North Tower, which was hit on its north side, tilted about 8 degrees to the south, before starting to fall. [National Institute of Standards and Technology, 9/2005, pp. 300, 308 pdf file] However, these findings are criticized by Canadian scientist Frank Greening. After examining photo and video evidence, Greening says that the South Tower tilted by no more than two degrees and the North Tower by no more than three degrees before collapse initiation. Greening also says that the tilt angles NIST gives cannot correspond to the downward movement of the towers’ walls NIST claims before they started to fall, and points out that the tilt angles NIST uses are inconsistent throughout its reports. Though Greening agrees with NIST that the towers were destroyed by the plane impacts and fire damage, he concludes that its computer model is “highly inaccurate and therefore of no value in explaining the demise of the Twin Towers.” [Greening, 11/2005 pdf file] Greening is a leading figure in the post-9/11 dispute over why the WTC collapsed and publishes a series of papers dealing with various aspects of the Twin Towers’ collapse. For example, a CBC documentary uses Greening for analysis of the WTC’s fall. [Canadian Broadcasting Corporation, 8/25/2005]
