Giuliani’s emergency command center.Giuliani’s emergency command center. [Source: CNN]New York City Mayor Rudolph Giuliani opens a $13 million emergency command center on the 23rd floor of World Trade Center Building 7. [Newsday, 9/12/2001] The center is intended to coordinate responses to various emergencies, including natural disasters like hurricanes or floods, and terrorist attacks. The 50,000 square foot center has reinforced, bulletproof, and bomb-resistant walls, its own air supply and water tank, beds, showers to accommodate 30 people, and three backup generators. It also has rooms full of video monitors from where the mayor can oversee police and fire department responses. It is to be staffed around the clock and is intended as a meeting place for city leaders in the event of an act of terrorism. [CNN, 6/7/1999; London Times, 9/12/2001; Glanz and Lipton, 2004, pp. 233] The center is ridiculed as “Rudy’s bunker.” [Time, 12/22/2001] Author Philip Shenon will later comment that it “seemed the supreme example of how Giuliani’s ego and arrogance knew no bounds after four years in office,” and: “WABC Radio mocked Giuliani with a name-that-bunker contest for its listeners. Among the most popular entries: ‘Rudy’s Nuclear Winter Palace’ and ‘The Nut Shell.’” It is criticized because of the cost and because of the location, next to the WTC towers, one of the city’s top terrorist targets. In addition, the high floor it is on means it is vulnerable to power, water, and elevator outages. [Shenon, 2008, pp. 346-347] Most controversial is the 6,000-gallon fuel tank. In 1998 and 1999, Fire Department officials warn that the fuel tank violates city fire codes and poses a hazard. According to one Fire Department memorandum, if the tank were to catch fire it could produce “disaster.” Building 7 will be destroyed late in the day on 9/11; some suspect this tank helps explains why.

[Source: San Diego Channel 10]9/11 hijackers Nawaf Alhazmi and Khalid Almihdhar arrive at Sorbi’s Flying Club, a small school in San Diego, and announce that they want to learn to fly Boeing airliners. Alhazmi had previously had a lesson at another nearby flying school (see April 4, 2000). [Washington Post, 9/30/2001] They are there with someone named “Hani”—possibly 9/11 hijacker Hani Hanjour—but only the two of them go up in an airplane. The 9/11 Commission will say that Hanjour is outside the US at this time, although some media reports will place him in San Diego (see (Early 2000-November 2000)). [South Florida Sun-Sentinel, 9/28/2001] Instructor Rick Garza says that the dream to fly big jets is the goal of practically every student who comes to the school, but he notices an unusual lack of any basic understanding of aircraft in these two. When he asks Almihdhar to draw the aircraft, Almihdhar draws the wings on backwards. Both speak English poorly, but Almihdhar in particular seems impossible to communicate with. Rather than following the instructions he was given, he would vaguely reply, “Very good. Very nice.” [Chicago Tribune, 9/30/2001] The two offer extra money to Garza if he will teach them to fly multi-engine Boeing planes, but Garza declines. [Washington Post, 9/30/2001] “I told them they had to learn a lot of other things first… It was like Dumb and Dumber. I mean, they were clueless. It was clear to me they weren’t going to make it as pilots.” [Observer, 10/7/2001 Sources: Rick Garza]

[Source: History Channel]9/11 hijacker Ziad Jarrah attends the Florida Flight Training Center (FFTC) in Venice, Florida, where he takes lessons in a Cessna 152. According to the FBI, he finishes his training there in December 2000. [Der Spiegel, 2002, pp. 12; US Congress, 9/26/2002] The school’s owner, Arne Kruithof, later says Jarrah is enrolled there until January 15, 2001. [Longman, 2002, pp. 91] The 9/11 Commission says he studies there until January 31, 2001. [9/11 Commission, 8/21/2004, pp. 12 pdf file] However, these latter two accounts conflict with other reports, according to which Jarrah is elsewhere at the same time (see Late November 2000-January 30, 2001). According to the 9/11 Commission, in early August, just weeks after commencing training, Jarrah gains a single-engine private pilot certificate. [9/11 Commission, 7/24/2004, pp. 224] However, Arne Kruithof says that although Jarrah eventually receives his private pilot license and instrument rating, he does not do so while at FFTC. Kruithof later claims that Jarrah becomes an “average” pilot, saying, “We had to do more to get him ready than others. His flight skills seemed to be a little bit out there.” [Longman, 2002, pp. 91] At the same time as Jarrah is in Venice, Mohamed Atta and Marwan Alshehhi attend Huffman Aviation, which is just up the road from FFTC. [Associated Press, 9/9/2002; 9/11 Commission, 7/24/2004, pp. 224] Yet no reports describe him ever meeting them while they are so near to each other. Ramzi bin al-Shibh, who shared an apartment in Hamburg with Mohamed Atta (see November 1, 1998-February 2001), is supposed to join Jarrah at FFTC, wiring the school a $2,200 deposit in August 2000, but is repeatedly unable to obtain the necessary US visa (see May 17, 2000-May 2001).

Huffman Aviation logo.Huffman Aviation logo. [Source: Huffman Aviation]9/11 hijackers Marwan Alshehhi and Mohamed Atta attend Huffman Aviation, a flight school in Venice, Florida and enroll in its Accelerated Pilot Program, aiming to get commercial pilot licenses. According to the school’s owner Rudi Dekkers, Atta already has a private pilot’s license—though where and how he gained this is unstated—and wants to obtain a commercial license. Alshehhi wants to obtain both licenses. They begin their training in a Cessna 172 with instructor Thierry Leklou. According to the 9/11 Commission, by the end of July both are already taking solo flights. However, in August Leklou complains to Chief Flight Instructor Daniel Pursell that the two are failing to follow instructions and have bad attitudes. Pursell considers expelling them, but, according to Dekkers, after a warning they improve their behavior and continue without further problems. [US Congress, 3/19/2002; 9/11 Commission, 7/24/2004, pp. 224, 227; St. Petersburg Times, 7/25/2004] Yet Pursell later testifies that the school’s instructors breathed “a collective sigh of relief” when the two left Huffman. [Associated Press, 3/23/2006] Furthermore, reportedly, “Atta and al-Shehhi would rent a plane from Huffman and be gone for days at a time, Pursell said. They could fly to 20 airports across the state and never be noticed.” [St. Petersburg Times, 7/25/2004] Mark Mikarts, another of the school’s instructors, says Atta has “big problems with authority,” and doesn’t take instructions well. [Wall Street Journal, 9/17/2001; 9/11 Commission, 8/21/2004, pp. 17 pdf file] Susan Hall, Huffman’s office manager, refers to Atta as “the little terrorist” while he is at the school, because, she later says, “I just didn’t like the aura he gave off.” [Reuters, 3/22/2006] In the middle of their training, in late September, Atta and Alshehhi enroll at another flight school, in nearby Sarasota. However, they are soon asked to leave it, and return to Huffman in October (see Late September-Early October 2000). While Atta and Alshehhi attend Huffman Aviation, another of the alleged hijackers, Ziad Jarrah, is taking lessons at a flight school just down the road from them (see (June 28-December 2000)). Yet no reports describe the three ever meeting up while they are all in Venice. According to official accounts, Atta and Alshehhi complete their schooling at Huffman on December 19, 2000, when they take their commercial pilot license tests. Rudi Dekkers says that after returning to the school to settle their bills, they leave and are never seen there again. [US Congress, 3/19/2002; 9/11 Commission, 8/21/2004, pp. 17 pdf file] Yet Daniel Pursell will later allege that early in 2001 the two are still connected with Huffman, being reported to the school for practicing nighttime landings in one of its planes at another Florida airport (see Between January and February 2001).

Hani Hanjour, from a 2000 US visa application.
Hani Hanjour, from a 2000 US visa application. [Source: 9/11 Commission]In January 2001, the Arizona flight school JetTech alerts the FAA about hijacker Hani Hanjour. No one at the school suspects Hanjour of terrorist intent, but they tell the FAA he lacks both the English and flying skills necessary for the commercial pilot’s license he has already obtained. For instance, he had taken classes at the University of Arizona but failed his English classes with a 0.26 grade point average. A JetTech flight school manager “couldn’t believe he had a commercial license of any kind with the skills that he had.” A former employee says, “I’m still to this day amazed that he could have flown into the Pentagon. He could not fly at all.” They also note he is an exceptionally poor student who does not seem to care about passing his courses. [New York Times, 5/4/2002; CBS News, 5/10/2002] An FAA official named John Anthony actually sits next to Hanjour in class and observes his skills. He suggests the use of a translator to help Hanjour pass, but the flight school points out that goes “against the rules that require a pilot to be able to write and speak English fluently before they even get their license.” [Associated Press, 5/10/2002] The FAA verifies that Hanjour’s 1999 pilot’s license is legitimate (see April 15, 1999), but takes no other action. However, his license should have been rejected because it had already expired in late 1999 when he failed to take a manadatory medical test. [Associated Press, 9/15/2001; CBS News, 5/10/2002] An Arizona FAA inspector later says, “There should have been a stop right then and there.” He will claim that federal law would have required Hanjour to be re-examined. [Associated Press, 6/13/2002] In February, Hanjour begins advanced simulator training, “a far more complicated task than he had faced in earning a commercial license.” [New York Times, 6/19/2002] The flight school again alerts the FAA about this and gives a total of five alerts about Hanjour, but no further action on him is taken. The FBI is not told about Hanjour. [CBS News, 5/10/2002] Ironically, in July 2001, Arizona FBI agent Ken Williams will recommend in a memo that the FBI liaison with local flight schools and keep track of suspicious activity by Middle Eastern students (see July 10, 2001).

bullet Marwan Alshehhi—first license, April 12, duplicate in June;

For instance, Nawaf Alhazmi had licenses from California, New York, and Florida at the same time, apparently all in the same name.

[Source: 9/11 Commission]The 13 hijackers commonly known as the “muscle” allegedly first arrive in the US. The muscle provides the brute force meant to control the hijacked passengers and protect the pilots. [Washington Post, 9/30/2001] Yet, according to the 9/11 Commission, these men “were not physically imposing,” with the majority of them between 5 feet 5 and 5 feet 7 tall, “and slender in build.” [9/11 Commission, 6/16/2004, pp. 8] According to FBI Director Mueller, they all pass through Dubai, United Arab Emirates, and their travel was probably coordinated from abroad by Khalid Almihdhar. [US Congress, 9/26/2002] However, some information contradicts their official arrival dates:
bullet April 23: Waleed Alshehri and Satam Al Suqami arrive in Orlando, Florida. Suqami in fact arrived before February 2001. A man named Waleed Alshehri lived with a man named Ahmed Alghamdi in Virginia and Florida between 1997 and 2000. However, it is not clear whether they were the hijackers or just people with the same name (see 1999). [Daily Telegraph, 9/20/2001] Alshehri appears quite Americanized in the summer of 2001, frequently talking with an apartment mate about football and baseball, even identifying himself a fan of the Florida Marlins baseball team. [Associated Press, 9/21/2001]
bullet May 2: Majed Moqed and Ahmed Alghamdi arrive in Washington. Both actually arrived by mid-March 2001. A man named Ahmed Alghamdi lived with a man named Waleed Alshehri in Florida and Virginia between 1997 and 2000. However, it is not clear whether they were the hijackers or just people with the same name (see 1999). [Daily Telegraph, 9/20/2001] Alghamdi apparently praises Osama bin Laden to Customs officials while entering the country and Moqed uses an alias (see May 2, 2001).
bullet May 28: Mohand Alshehri, Hamza Alghamdi, and Ahmed Alnami allegedly arrive in Miami, Florida. Alnami may have a suspicious indicator of terrorist affiliation in his passport (see April 21, 2001), but this is apparently not noticed by US authorities. The precise state of US knowledge about the indicator at this time is not known (see Around February 1993). The CIA will learn of it no later than 2003, but will still not inform immigration officials then (see February 14, 2003). According to other reports, however, both Mohand Alshehri and Hamza Alghamdi may have arrived by January 2001 (see January or July 28, 2001).
bullet June 8: Ahmed Alhaznawi and Wail Alshehri arrive in Miami, Florida. Alhaznawi may have a suspicious indicator of terrorist affiliation in his passport (see Before November 12, 2000), but this is apparently not noticed by US authorities.
bullet June 27: Fayez Banihammad and Saeed Alghamdi arrive in Orlando, Florida.
bullet June 29: Salem Alhazmi and Abdulaziz Alomari allegedly arrive in New York. According to other reports, however, Alhazmi arrived before February 2001. Alhazmi has a suspicious indicator of terrorist affiliation in his passport (see June 16, 2001), but this is apparently not noticed by US authorities.
After entering the US (or, perhaps, reentering), the hijackers arriving at Miami and Orlando airports settle in the Fort Lauderdale, Florida, area along with Mohamed Atta, Marwan Alshehhi, and Ziad Jarrah. The hijackers, arriving in New York and Virginia, settle in the Paterson, New Jersey, area along with Nawaf Alhazmi and Hani Hanjour. [US Congress, 9/26/2002] Note the FBI’s early conclusion that 11 of these muscle men “did not know they were on a suicide mission.” [Observer, 10/14/2001] CIA Director Tenet’s later claim that they “probably were told little more than that they were headed for a suicide mission inside the United States” [US Congress, 6/18/2002] and reports that they did not know the exact details of the 9/11 plot until shortly before the attack [CBS News, 10/9/2002] are contradicted by video confessions made by all of them in March 2001 (see (December 2000-March 2001)).

Several of the 9/11 hijackers make trips to Las Vegas and the west coast over the summer:
bullet May 24-27: Marwan Alshehhi flies to Vegas (see May 24-27, 2001);
bullet June 7-10: Ziad Jarrah takes a trip to Vegas (see June 7-10, 2001);
bullet June 28-July 1: Mohamed Atta takes his first trip to Vegas, flying from Fort Lauderdale to Boston and then, the next day, to Las Vegas via San Francisco with United Airlines. He stays there three nights, then returns to Boston via Denver, and flies to New York the next day;
bullet July 31-August 1: Waleed Alshehri flies from Fort Lauderdale to Boston and then takes American Airlines flight 195 to San Francisco the next day. After spending a night at the La Quinta Inn, he returns to Miami via Las Vegas; [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006, pp. 1-2, 16, 18 pdf file; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006, pp. 55-7 pdf file]
bullet August 1: Actor James Woods sees four people he will later suspect are hijackers, including individuals he believes to be Khalid Almihdhar and Hamza Alghamdi, on a transcontinental flight (see August 1, 2001). Abdulaziz Alomari is reported to try to get into the cockpit on a different flight from Vegas on the same day (see August 1, 2001);
bullet August 13-14: Atta, Hani Hanjour, and Nawaf Alhazmi all fly to Vegas, possibly meeting some other hijackers there (see August 13-14, 2001).
Nawaf Alhazmi and Khalid Almihdhar also made frequent car trips to Las Vegas from San Diego, where they lived in 2000. [Los Angeles Times, 9/1/2002; McDermott, 2005, pp. 192] The reason for these trips is never definitively determined, although there will be speculation the hijackers are casing aircraft similar to those they will hijack on 9/11. The 9/11 Commission will comment, “Beyond Las Vegas’s reputation for welcoming tourists, we have seen no credible evidence explaining why… the operatives flew to or met in Law Vegas.” [9/11 Commission, 7/24/2004, pp. 242, 248] After 9/11, it will be reported that the hijackers may use these cross-country flights to take pictures of airline cockpits and check out security at boarding gates. During the flights, the hijackers apparently take notes, watch the crews, and even videotape them. There are some reports that two, or perhaps more, of the hijackers sit in “jumpseats” in the pilot’s cabin, a courtesy extended by airlines to other pilots, during the surveillance flights (see Summer 2001) and on the day of 9/11 itself (see November 23, 2001). [Boston Globe, 11/23/2001; Associated Press, 5/29/2002] There are reports that the hijackers drink alcohol, gamble, and frequent strip clubs while they are in Las Vegas. For example, according to a dancer named “Samantha,” Marwan Alshehhi stares up at her blankly while she “undulate[s] her hips inches from his face” and only gives her $20, although he is a “light drinker.” [San Francisco Chronicle, 10/4/2001; Newsweek, 10/15/2001]

Rodriguez is cleaning washrooms on the Trade Center’s concourse level one weekend, when a person he later believes to have been Alshehri approaches him and asks, “[H]ow many public bathrooms are in this area?” Rodriguez says he finds this “very strange.” After 9/11, he will recognize the man from newspaper photos as having been the suspected hijacker. He will say he is “very certain, I’ll give it 90 percent” that the man he’d seen was Alshehri. He will tell the FBI of this encounter, but will never hear back from them. FBI officials later say they have never heard of Rodriguez, but they do not discount his story. [Daily Telegraph, 6/15/2004; MSNBC, 6/15/2004; New York Daily News, 6/15/2004] According to FBI and 9/11 Commission accounts, Alshehri has only recently entered the US, on May 28, 2001 (see April 23-June 29, 2001), though other reports suggest he was in the country several months earlier (see January or July 28, 2001).

bullet Hani Hanjour opens an account with First Union National Bank on August 23, 2001 with a $50 deposit. He then attempts to withdraw $5,000 on September 5 and $4,900 from it on September 7, despite it containing nothing but the original $50. Unable to make the withdrawal, he cashes a $20 check instead. Hanjour closes the account the next day. [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006 pdf file; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006 pdf file; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006 pdf file] These hijackers will subsequently fly on three of the planes on 9/11. In its Terrorist Financing monograph the 9/11 Commission will note: “Among other things they used the debit cards to pay for hotel rooms—activity that would have enabled the FBI to locate them, had the FBI been able to get the transaction records fast enough. Moreover, Alhazmi used his debit card on August 27 to buy tickets for himself… and fellow Flight 77 hijacker Salem Alhazmi. If the FBI had found either Almihdhar or Nawaf Alhazmi, it could have found the other. They not only shared a common bank but frequently were together when conducting transactions. After locating Almihdhar and Alhazmi, the FBI could have potentially linked them through financial records to the other Flight 77 hijackers… Nawaf Alhazmi and Flight 77 pilot Hani Hanjour had opened separate savings accounts at the same small New Jersey bank at the same time and both gave the same address. On July 9, 2001, the other Flight 77 muscle hijacker, Majed Moqed, opened an account at another small New Jersey bank at the same time as Nawaf Alhazmi, and used the same address. Given timely access to the relevant records and sufficient time to conduct a follow-up investigation, the FBI could have shown that Hani Hanjour, Majed Moqed, and Salem al Hazmi were connected to potential terrorist operatives Almihdhar and Nawaf Alhazmi.” [9/11 Commission, 8/21/2004, pp. 58-59, 141 pdf file] The hijackers also open several other bank accounts (see June 28-July 7, 2000).

Silverstein Properties’ lease will cover the roughly 10 million square feet of office space of the Twin Towers and Buildings 4 and 5. Silverstein Properties already owns Building 7 of the WTC, which it built in 1987. This is the only time the WTC has ever changed hands since it was opened in 1973.

[Wall Street Journal, 5/12/2007] Silverstein and Westfield are given the right to rebuild the structures if they are destroyed. [New Yorker, 5/20/2002]
Silverstein Properties Not the Highest Bidder - Silverstein Properties’ bid for the WTC, at $3.22 billion, was the second highest after Vornado Realty Trust’s, at $3.25 billion. Silverstein Properties won the contract only after protracted negotiations between the Port Authority and Vornado Realty Trust failed. The privatization of the WTC has been overseen by Lewis M.

Silverstein's Lenders Want More Insurance - The Port Authority had carried only $1.5 billion in insurance coverage on all its buildings, including the WTC, but Silverstein’s lenders insist on more, eventually demanding $3.55 billion in cover. [American Lawyer, 9/3/2002] After 9/11, Larry Silverstein will claim the attacks on the World Trade Center constituted two separate events, thereby entitling him to a double payout totaling over $7 billion. [Daily Telegraph, 10/9/2001; Guardian, 8/18/2002] Eventually, after several years of legal wrangling, a total of $4.55 billion of insurance money will be paid out for the destruction of the WTC (see May 23, 2007). Most of this appears to go to Silverstein Properties. How much goes to Westfield America Inc. is unclear. [New York Post, 5/24/2007]

New York City’s Office of Emergency Management (OEM) purchases crisis management computer software that it plans to launch for use on September 17, and that will significantly help the city’s response to the 9/11 attacks. [Wall Street Journal, 10/23/2001; Wired News, 11/2/2001] The OEM is intended to improve New York’s response to major incidents, including terrorist attacks, and play a key role in managing the city’s overall response to an incident. [9/11 Commission, 7/24/2004, pp. 283-284] The software it buys, called E Team, is an emergency and event management product created by E Team Inc., a small company based in Canoga Park, California. [Wall Street Journal, 10/23/2001; e-ProWire, 5/22/2002] John Hughes, a vice president of E Team Inc., in fact used to be the deputy director of the New York City OEM. E Team was originally created for use by the military in battlefield coordination, but the software can now be used by public agencies and private companies, to “prepare for, respond to, and recover from disasters and emergencies of all types.” [Los Angeles Times, 12/11/2000; California Technology Ventures, 10/16/2001; Wired News, 11/2/2001] It enables officials to coordinate thousands of workers and hundreds of agencies. [Wall Street Journal, 10/23/2001] The OEM plans to install the software on special server computers in its Emergency Operations Center on the 23rd floor of World Trade Center Building 7, and to launch the E Team system on September 17. [Wired News, 11/2/2001; Council of the City of New York, 8/2002, pp. 22 pdf file] But as a result of the terrorist attacks on September 11, the system will instead go into use on September 14, at OEM’s temporary command center at Pier 92 on the Hudson River (see September 14, 2001). [Wall Street Journal, 10/23/2001; e-ProWire, 5/22/2002] Every government organization supporting the OEM command center after 9/11 will use E Team to coordinate its rescue and recovery efforts with the OEM. [California Technology Ventures, 10/16/2001] A report later published by New York City Council’s Select Committee on Technology in Government will say it is ironic that the OEM decides to buy the E Team software in the month before the terrorist attacks in New York take place. The report will comment that the OEM buys the software “in order to better manage precisely the emergency situations that the city faced after 9/11.” [Council of the City of New York, 8/2002, pp. 22 pdf file]

9/11 hijacker Mohamed Atta receives $100,000 from accounts in Pakistan. The money is transferred to two of his accounts in Florida. [Fox News, 10/2/2001; Associated Press, 10/2/2001; US Congress, 10/3/2001; CNN, 10/6/2001; CNN, 10/8/2001] This will later be reported in various media. For example, ABC News will say that federal authorities track “more than $100,000 from banks in Pakistan to two banks in Florida to accounts held by suspected hijack ringleader Mohamed Atta.” [ABC News, 9/30/2001] Law enforcement sources will tell CNN, “[T]he wire transfers from Pakistan were sent to Atta through two banks in Florida.” [CNN, 10/1/2001] One of the hijackers’ financiers, the Pakistan-based Omar Saeed Sheikh, is said to wire Atta around $100,000 in August (see Early August 2001). The transfers from Pakistan will be disclosed a few weeks after 9/11 but will then fade from view (see September 30-October 7, 2001), until 2003 when John S. Pistole, deputy assistant director of the FBI’s Counterterrorism Division, tells the Senate Committee on Governmental Affairs that the FBI has traced the origin of funding for 9/11 back to accounts in Pakistan (see July 31, 2003). However, in 2004 the 9/11 Commission will fail to mention any funding coming directly from Pakistan (see Late-September 2001-August 2004).

Developer Larry Silverstein, who recently took over the lease of the WTC (see July 24, 2001), had been highly impressed with O’Neill but insisted he start in the post no later than the first week of September, when his firm Silverstein Properties is set to assume control of the buildings. O’Neill had agreed to this.

George Tabeek.George Tabeek. [Source: Fairleigh Dickinson University]George Tabeek, a security manager with the Port Authority of New York and New Jersey, expresses his concerns about an aircraft crashing into the World Trade Center, perhaps in a terrorist attack. [CBS News, 2/11/2009; New Jersey Star-Ledger, 9/6/2011] The Port Authority was, until late July, responsible for the management and operation of the WTC (see July 24, 2001), and most Port Authority World Trade Department employees are still working in the WTC. [Port Authority of New York and New Jersey, 7/24/2001; IREIzine, 7/26/2001; 9/11 Commission, 7/24/2004, pp. 281]
Possibility of Plane Hitting WTC Discussed - Tabeek, the Port Authority’s security manager for the WTC since 1999, will later say that, following the 1993 bombing of the WTC (see February 26, 1993), the Port Authority “put thousands and thousands of hours into safety construction and safety procedures.” Over $100 million has been spent on improving security and fire safety. Therefore, according to Tabeek, “the World Trade Center was safer on 9/11 than 99 percent of the buildings in America.” Tabeek will say: “We were already looking into bio-chem. We were talking about weapons of mass destruction.” He will add that, just two weeks before 9/11, “[W]e talked about ever getting hit by a plane, but it was never in our wildest dreams a commercial airliner.” [FDU Magazine, 6/2008; CBS News, 2/11/2009]
Possibility of Attack Using Plane Discussed with New Head of Security - Tabeek discusses the possibility of a plane hitting the WTC again on September 6, the Thursday before 9/11. That evening, John O’Neill, the new head of security at the WTC (see August 23, 2001), calls him to a conference room in the South Tower, to discuss security and “threat assessment.” During the meeting, Tabeek describes the improved security at the WTC, telling O’Neill: “We’re 99 percent locked down. You’re not going to get in here with a bomb that’s going to do substantial damage within the building, because we minimized that.” According to Tabeek, O’Neill asks: “Okay, you say to me we’re 99 percent locked down. What’s the other 1 percent?” Tabeek replies, “A plane.” O’Neill says, “Come on, you’re grabbing at straws.” But Tabeek tells him, “No, in ‘93 we’re an American economic bad cop… and now we’re an American-Israeli economic bad cop, more of a threat today than we ever were.” He adds that the plane involved would be “a corporate jet slamming into the building,” with “minimal loss of life, minimal economic loss.” Tabeek will later comment, “I never expected something bigger.” [New Jersey Star-Ledger, 9/6/2011] An analysis carried out on behalf of the Port Authority after the 1993 WTC bombing identified the scenario of terrorists deliberately crashing a plane into the Twin Towers as one of a number of possible threats (see After February 26, 1993). [Jenkins and Edwards-Winslow, 9/2003, pp. 11 pdf file] Tabeek will tell one magazine, “We had planned for the possibility of a small airplane—a corporate jet, maybe—crashing into one of the [WTC] buildings by accident.” [FDU Magazine, 6/2008]

[Source: ArcNews]At Pier 92 on the Hudson River, preparations are underway for a training exercise due to take place there the following day. The exercise, called Tripod, which had been scheduled months earlier, is intended to test how well New York’s Office of Emergency Management (OEM) can administer treatment in response to a biological-terrorism attack (see September 12, 2001). [New York Magazine, 10/15/2001; Giuliani, 2002, pp. 355] Pier 92, located just over four miles north-northwest of the World Trade Center, has been set up as a model distribution station where the simulated victims will be treated. [Jenkins and Edwards-Winslow, 9/2003, pp. 15 and 20 pdf file] Ken Longert, the owner of a theatrical lighting business, arrives at the pier at 7:00 a.m. to help get the place ready for the exercise. He will later recall, “Two or three hundred cadets [presumably with the New York police and fire departments] were there, learning the proper procedures in case some kind of disaster hit New York.” Longert will recall that, seconds after the second WTC tower is hit at 9:03, “all the people from OEM disappeared” from the pier.

[Real Deal, 1/2004] Two of Silverstein’s children—his son, Roger, and daughter, Lisa—work for his company and have been regularly attending meetings with WTC tenants at Windows on the World (the restaurant at the top of the North Tower). Yet this morning they are running late. According to the New York Observer, “If the attack had happened just a little later, Mr. Silverstein’s children would likely have been trapped at Windows.” [New York Observer, 3/17/2003] Fifty-four of Silverstein Properties’ 160 staff are in the North Tower when it is hit, and four of them die.

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, 8/12/2002; 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).

As they look out of the window at the burning North Tower, Odermatt debriefs Bylicki and instructs him to open the EOC for a fully staffed operation. Bylicki therefore sets about activating the operations center. [Bylicki, 6/19/2003]
Staffers Call Agencies and Tell Them to Send Their Representatives - EOC personnel start contacting agencies, including the New York Fire and Police Departments and the Department of Health, and instruct them to send their designated representatives to the center. They also call the State Emergency Management Office (SEMO) and the Federal Emergency Management Agency (FEMA), which they ask to send at least five federal urban search and rescue teams. [9/11 Commission, 5/18/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 293] Meanwhile, Bylicki helps the OEM’s Watch Command handle an “enormous influx” of phone calls, many of which are from senior city officials. [Bylicki, 6/19/2003]
Activation Proceeds without Any Problems - EOC personnel initially struggle to make sense of what has happened at the Twin Towers. [Wachtendorf, 2004, pp. 77] However, the activation apparently proceeds without any problems. Firefighter Timothy Brown, a supervisor at the OEM, is instructed by Calvin Drayton, a deputy director with the OEM, to go up to the 23rd floor of WTC 7 and make sure that personnel are getting the EOC up and running, and the Watch Command is being properly supervised. He goes up to the 23rd floor and first checks the Watch Command. He sees that its supervisor, Mike Lee, has things under control. Then, in the EOC, he sees Michael Berkowitz, a supervisor with the OEM, powering up all the computers and television screens necessary to handle the emergency, and beginning to notify the dozens of agencies that need to send representatives to the center. Berkowitz tells Brown he has the manpower he needs to get the center up and running. “I was very comfortable that OEM was beginning to do what we do in a major emergency,” Brown will later recall. Activating the EOC is something OEM personnel have “drilled for and drilled for and drilled for… and so we were very good at it,” he will comment. [City of New York, 1/15/2002; Project Rebirth, 6/30/2002 pdf file; Firehouse, 1/31/2003]
Center Is Designed for Managing a Crisis - The EOC, which opened in 1999 (see June 8, 1999), is a state-of-the-art facility designed to operate as a stand-alone center from which the city government can operate during a crisis. [City of New York, 2/18/2001] It is one of the most sophisticated facilities of its type in the world. It includes a communications suite, a conference room, a press briefing room, and a large number of staff offices, and has numerous computer-equipped workstations. [Disasters, 3/2003 pdf file] It has enough seating for 68 agencies to operate during an emergency. [City of New York, 2/18/2001] However, it will be evacuated at 9:30 a.m. due to reports of further unaccounted-for planes, according to the 9/11 Commission Report (see (9:30 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 305] Other accounts will indicate that it may be evacuated at an earlier time, possibly even before the second crash at the WTC occurs (see (Soon After 8:46 a.m.-9:35 a.m.) September 11, 2001 and (Shortly Before 9:03 a.m.) September 11, 2001).

Richard SheirerRichard Sheirer [Source: Publicity photo]Richard Sheirer is in a meeting at New York City Hall when he is informed by telephone of the first plane hitting the World Trade Center. Sheirer is the director of the Mayor’s Office of Emergency Management (OEM), which was set up in 1996 to coordinate the city’s overall response to major incidents, including terrorism (see 1996). It has an emergency command center on the 23rd floor of WTC 7, specially intended for coordinating the response to catastrophes such as terrorist attacks (see June 8, 1999). Yet instead of going to this, Sheirer heads to the North Tower, and arrives at the fire command post set up in its lobby before the second crash at 9:03 a.m. [New York Magazine, 10/15/2001; 9/11 Commission, 5/18/2004 pdf file] John Odermatt, Sheirer’s top deputy, also goes to the North Tower and says that, after the first plane hit, he leaves only two staffers at the command center. John Farmer, who heads the 9/11 Commission unit that assesses the city response to the attacks, will find it “strange that Sheirer, four OEM deputies, and a field responder went straight to the North Tower… rather than to the nearby emergency command center.” Journalists Wayne Barrett and Dan Collins will conclude, “[T]he command center was out of business from the outset.” [Barrett and Collins, 2006, pp. 31 and 34] Sheirer stays at the North Tower lobby until soon after 9:30 a.m., when Mayor Giuliani requests he joins him at the temporary command post at 75 Barclay Street (see (9:50 a.m.-10:10 a.m.) September 11, 2001). [9/11 Commission, 5/18/2004 pdf file] John Farmer will later complain, “We [the 9/11 Commission] tried to get a sense of what Sheirer was really doing. We tried to figure it out from the videos. We couldn’t tell. Everybody from OEM was with him, virtually the whole chain of command. Some of them should have been at the command center.” Fire Captain Kevin Culley, who works as a field responder at OEM, is later asked why most of the OEM’s top brass were with him at the scene of the incident. He says, “I don’t know what they were doing. It was Sheirer’s decision to go there on his own. The command center would normally be the focus of a major event and that would be where I would expect the director to be.” When the 9/11 Commission later investigates OEM’s shortcomings on 9/11, “No rationale for Sheirer’s prolonged lobby stay, no information conveyed to commanders, and no steps to coordinate the response” will be discovered.

The jet fuel that spilled from Flight 11 when it hit the North Tower (see 8:46 a.m. September 11, 2001) has mostly burned up by this time. The National Institute of Standards and Technology (NIST), which 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 11, a Boeing 767, had a fuel capacity of 23,980 gallons, but was only carrying about 10,000 gallons when it hit the WTC. NIST will estimate that less than 1,500 gallons were consumed in a fireball inside the tower and a comparable amount was consumed in the fireballs outside the building. Therefore, approximately 7,000 gallons 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 have fewer combustibles than some 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 reaches a temperature above 600°C (see August 27, 2003). Although 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. 20, 29, 24, 77] The jet fuel will also burn up in the South Tower about 10 minutes after it is hit (see 9:13 a.m. September 11, 2001).

After the first World Trade Center tower is hit, Barry Jennings, a City Housing Authority worker, and Michael Hess, New York’s corporation counsel, head up to the emergency command center of the Mayor’s Office of Emergency Management (OEM), which is on the 23rd floor of WTC 7. [Associated Press, 9/11/2001] The center, opened in 1999, is intended to coordinate responses to various emergencies, including terrorist attacks (see June 8, 1999). [CNN, 6/7/1999] However, Hess and Jennings find no one there. [National Institute of Standards and Technology, 9/2005, pp. 109-110; BBC, 7/6/2008]
Center Is Empty; Jennings Warned to Leave - Jennings will describe that, when he arrives at the emergency command center, “To my amazement, nobody’s there.” He says: “I saw coffee that was still hot, that was still smoldering. They had screens all over the place, but the screens were blank. So I didn’t know what was going on.” He then phones several individuals, including one of his superiors. When Jennings says where he is, the superior responds: “Get out of there. Get out of there now.” Hess then runs back into the center, after having found the stairwell, and says: “We’re the only ones up here. We gotta get out of here.” [Dylan Avery, 2007; BBC, 7/6/2008]
9/11 Commission Claims Command Center Not Evacuated until Later - Yet, according to the 9/11 Commission, “After the South Tower was hit [at 9:03], OEM senior leadership decided to remain in its ‘bunker’ and continue conducting operations, even though all civilians had been evacuated from 7 WTC.” The Commission will claim the emergency command center is not evacuated until 9:30 a.m. (see (9:30 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 305] But according to the London Independent, Hess and Jennings arrive there by the time the South Tower is hit, which suggests the center is evacuated earlier than officially claimed. [Independent, 9/13/2001] Jennings himself will recall, “I had to be inside on the 23rd floor when the second plane hit.” [Dylan Avery, 2007] The possibility that the emergency command center is evacuated earlier than the 9/11 Commission claims is partly confirmed by OEM Commissioner John Odermatt, who later says that after the first plane hit the WTC, he left only two staffers there (see (Soon After 8:46 a.m.-9:35 a.m.) September 11, 2001). [Barrett and Collins, 2006, pp. 34] Jennings and Hess subsequently head down the stairs, but will become trapped in WTC 7, and have to be rescued by firefighters (see 12:10 p.m.-12:15 p.m. September 11, 2001).

According to a soldier at the scene, WTC Building 7 is evacuated before the second tower is hit. [Fort Detrick Standard, 10/18/2001] The National Institute of Standards and Technology (NIST) states, “As the second aircraft struck WTC 2, a decision was made to evacuate WTC 7.” This would be just after the Port Authority Police Department called for the evacuation of the entire WTC complex (see 8:59 a.m.-9:02 a.m. September 11, 2001). But by this time, “many WTC 7 occupants [have] already left the building and others [have] begun a self-evacuation of the building.” [National Institute of Standards and Technology, 9/2005, pp. 109] All individuals in the Secret Service’s New York field office, located in WTC 7, were ordered to evacuate after the first attack, and they are in the process of doing so when the second plane hits the South Tower. [PCCW Newsletter, 3/2006] The Secret Service has a Stinger missile secretly stored in the WTC, to be used to protect the president if there were an attack on the city when he visits it. [Weiss, 2003, pp. 379] Presumably, this missile is abandoned with the evacuation. The Office of Emergency Management’s command center, on the 23rd floor of WTC 7, is not evacuated until later, at 9:30 a.m. (see (9:30 a.m.) September 11, 2001).

Transportation Secretary Norman Mineta. [Source: US Department of Transportation]Transportation Secretary Norman Mineta arrives at the White House bunker—the Presidential Emergency Operations Center (PEOC)—containing Vice President Dick Cheney and others. Mineta will tell NBC News that he arrives there at “probably about 9:27,” though he later says to the 9/11 Commission that he arrives at “about 9:20 a.m.” He also later recalls that Cheney is already there when he arrives. [MSNBC, 9/11/2002; 9/11 Commission, 5/23/2003; St. Petersburg Times, 7/4/2004; Academy of Achievement, 6/3/2006] This supports accounts of Cheney reaching the bunker not long after the second WTC crash (see (Shortly After 9:03 a.m.) September 11, 2001). Questioned about this in 2007 by an activist group, Mineta will confirm that Cheney was “absolutely… already there” in the PEOC when he arrived, and that “This was before American Airlines [Flight 77] went into the Pentagon,” which happens at 9:37. Yet, while admitting there is “conflicting evidence about when the vice president arrived” in the PEOC, the 9/11 Commission will conclude that the “vice president arrived in the room shortly before 10:00, perhaps at 9:58.” Mineta also later claims that when he arrives in the PEOC, Mrs. Lynne Cheney, the wife of the vice president, is already there. Yet the 9/11 Commission will claim she only arrives at the White House at 9:52 (see (9:55 a.m.) September 11, 2001).

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).

[New York Times, 6/8/1999] However, it was evacuated at around 9:30 a.m., according to the 9/11 Commission Report, although other accounts will suggest the evacuation occurs at an earlier or later time (see (Soon After 8:46 a.m.-9:35 a.m.) September 11, 2001, (Shortly Before 9:03 a.m.) September 11, 2001, and (9:30 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 305; National Institute of Standards and Technology, 9/2005, pp. 109; Barrett and Collins, 2006, pp. 34] OEM personnel therefore now have to operate from the their command bus. [Jenkins and Edwards-Winslow, 9/2003, pp. 20 pdf file; 9/11 Commission, 4/7/2004] The bus, known as the Interagency Command Center (ICC), is equipped with computers, a state-of-the-art communications system, and on-board electrical generation. It also has its own conference room. [Wall Street Journal, 9/21/2001; Jenkins and Edwards-Winslow, 9/2003, pp. 20 pdf file; Power, 2004, pp. 172] It can be deployed to the location of a major emergency, to serve as an on-scene command post for coordinating interagency operations and communications. [City of New York, 2001, pp. 8 pdf file] The OEM’s emergency plans and vital records are kept in WTC 7, and, due to the evacuation of the command center, are now inaccessible. Fortunately, after they move to the ICC, OEM personnel are able to implement their emergency action plans from memory and by utilizing their combined knowledge. [Jenkins and Edwards-Winslow, 9/2003, pp. 20 pdf file] After the Twin Towers collapse, the ICC will move to a firehouse on Houston Street, to provide support to Mayor Rudolph Giuliani and his entourage, who have set up a temporary headquarters at that location (see (After 10:28 a.m.-12:00 pm.) September 11, 2001). [Wall Street Journal, 9/21/2001; 9/11 Commission, 4/7/2004]

At some point after the White House is ordered to evacuate and while Air Force One is preparing to take off in Florida, counterterrorism “tsar” Richard Clarke activates the Continuity of Government (COG) plan. The coordinator for Continuity of Government has joined Clarke in the White House Situation Room. Clarke asks, “How do I activate COG?” Recalling this conversation, he will later comment, “In the exercises we had done, the person playing the president had always given that order.” But the coordinator replies, “You tell me to do it.” Soon after, Clarke instructs him, “Go.” [Clarke, 2004, pp. 8]
First Time COG Plan Activated - The Continuity of Government plan, which dates back to the Reagan administration, had originally prepared to set up a new leadership for the US in the event of a nuclear war. This is apparently the first time it has ever been put into effect. Clarke will recall, “Every federal agency was ordered… to activate an alternative command post, an alternative headquarters outside of Washington, DC, and to staff it as soon as possible.” Cabinet officers are dispatched around the country, and people in Congress are taken to alternative locations.
Clarke Regularly Particiated in COG Exercises - Since the 1980s, Clarke has in fact been a regular participant in secret COG exercises that rehearsed this plan (see (1984-2004)). [Washington Post, 4/7/2004; ABC News, 4/25/2004] Vice President Dick Cheney and Secretary of Defense Donald Rumsfeld also participated (see 1981-1992). [Atlantic Monthly, 3/2004] Kenneth Duberstein, formerly President Reagan’s White House chief of staff, who took part in the exercises as well, will recall: “I said to myself, as we proceeded through the day [of 9/11], ‘It’s working.’ All those days of patriotic duty were coming back and they were working.” According to ABC News, “If executive branch leaders and large numbers of congressmen had been killed in an attack on the United States, the plan could have gone further, officials suggest, perhaps even with non-elected leaders of the United States taking control and declaring martial law.” [ABC News, 4/25/2004] According to a White House timeline of the events of 9/11, it is in fact Cheney that “orders implementation of Continuity of Government and Continuity of Operations procedures,” at 9:55 a.m., although, according to the Washington Post, Cheney only “officially implemented the emergency Continuity of Government orders,” rather than activating the plan.

After spending about 40 minutes at the disaster scene, on the World Trade Center site, New York City Mayor Rudolph Giuliani relocates to a small office building at 75 Barclay Street, about two blocks from the WTC, hoping to establish a command post there. His usual command center, in WTC 7, was evacuated at around 9:30 a.m. (see (9:30 a.m.) September 11, 2001). With him are several colleagues, including Police Commissioner Bernard Kerik and Office of Emergency Management Director Richard Sheirer. [Kerik, 2001, pp. 334; Giuliani, 2002, pp. 10; 9/11 Commission, 5/18/2004 pdf file; 9/11 Commission, 5/19/2004; Barrett and Collins, 2006, pp. 10] While at Barclay Street, Giuliani is able to get in touch with the White House, and speaks to Chris Henick, the deputy political director to President Bush (see 9:58 a.m. September 11, 2001). Immediately afterwards, he receives a phone call from Vice President Cheney, though this is cut off before either one is able to speak. Giuliani also claims he is given advance warning of the South Tower’s collapse while at this command post (see (Before 9:59 a.m.) September 11, 2001). After the South Tower collapses outside, Giuliani and his colleagues all decide to evacuate, going through the basement into a neighboring building, 100 Church Street. They will then leave this and head north, being joined by cameras and press. [Fink and Mathias, 2002, pp. 112; 9/11 Commission, 5/19/2004; Barrett and Collins, 2006, pp. 348]

Steve Lanoce.Steve Lanoce. [Source: Gamezebo]A group of police officers tries to enter World Trade Center Building 7 in order to get out of the WTC plaza, but they find the door is locked and the building is on fire. The seven officers are members of New York Police Department’s Emergency Service Unit (ESU). They were about 60 yards north of the South Tower when it collapsed, at 9:59 a.m. (see 9:59 a.m. September 11, 2001). When the dust began to clear, they made their way to the WTC plaza. But as they then tried to get out of the plaza, they found that every corner they ran to was blocked.
Officers Find the Door to WTC 7 Is Locked - The ESU officers now notice the bridge that leads from the plaza to WTC 7, and wonder if they can get out of the plaza by entering WTC 7 and then making their way down to the street below. [Tactical Edge, 6/2002 pdf file; Appel, 2009, pp. 99-100] WTC 7, a 47-story office building, is located to the north of the Twin Towers. It is linked to the main WTC complex by a glass-enclosed pedestrian bridge at the third-floor level. [Federal Emergency Management Agency, 5/1/2002, pp. 5-2; National Institute of Standards and Technology, 11/2008, pp. 2] The officers walk across the bridge, but when they reach the door that leads into WTC 7 they find it is locked. “Why anyone would lock a door under these circumstances was anybody’s guess,” author Anthea Appel will later comment.
Officers Find WTC 7 Is on Fire - One officer, Steve Lanoce, decides to try to break the door. He takes out his handgun and fires a shot at the bottom glass pane of the door. The glass, however, turns out to be bullet-proof and cracks but does not break. Furthermore, Lanoce’s shot sets off the burglar alarm in WTC 7. Fortunately, Lanoce’s colleagues are able to kick in the cracked glass and create an opening large enough to crawl through. They find, though, that the building on the other side of the door is on fire and they have to jump back to avoid the flames. [Tactical Edge, 6/2002 pdf file; Appel, 2009, pp. 99-100]
WTC 7 Suffered Only Minor Damage When the South Tower Collapsed - The cause of the fire in WTC 7 is unclear. The National Institute of Standards and Technology, which will investigate the collapse of WTC 7 that occurs later today (see (5:20 p.m.) September 11, 2001), will state that the building suffered only minor damage when the South Tower collapsed. “A few windows on lower floors of the south face of WTC 7 were broken, and dust and small debris were deposited in the third-floor lobby,” it will describe. However, it will add, “None of the large pieces of debris from [the South Tower] hit WTC 7 because of the large distance between the two buildings and there was no evidence of structural damage to WTC 7.” [National Institute of Standards and Technology, 11/2008, pp. 16] The ESU officers then notice a stream of people making their way out of the North Tower. They therefore abandon their plan to get out of the WTC complex and instead go to help evacuate the civilians from the tower. [Tactical Edge, 6/2002 pdf file; Appel, 2009, pp. 101]

World Trade Center Building 7 (WTC 7) suffers fires on several floors, some of which last until 5:20 p.m., when the building collapses. [National Institute of Standards and Technology, 8/21/2008] WTC 7 is a 47-story office building located just north of the Twin Towers. It is damaged when the north WTC tower (WTC 1) collapses at 10:28 a.m. (see 10:28 a.m. September 11, 2001). [National Institute of Standards and Technology, 11/2008, pp. 2, 16]
Fires Started by Collapse Debris - Two official reports on the collapse of WTC 7 will tentatively conclude that fires in this building are initiated by debris that is ejected when the North Tower collapses (see 10:28 a.m. September 11, 2001). In a 2002 report (see May 1, 2002), the Federal Emergency Management Agency (FEMA) will state, “It is likely that fires” in WTC 7 “started as a result of debris from the collapse of WTC 1.” [Federal Emergency Management Agency, 5/1/2002, pp. 5-20] In a 2008 report (see November 20, 2008), the National Institute of Standards and Technology (NIST) will state, “Most likely, the WTC 7 fires began as a result of burning debris from the collapse of WTC 1.” However, NIST will add, “visual evidence of fires in the building was not available until around noon.” [National Institute of Standards and Technology, 11/2008, pp. 18]
Fires Spread in WTC 7 - According to NIST, fires are ignited “on at least 10 floors” of WTC 7, but “only the fires on floors 7 through 9 and 11 through 13 grew and lasted until the time of the building collapse.” [National Institute of Standards and Technology, 11/2008, pp. xxxvi] NIST will state, “Early fires were seen on the southwest corner of floors 19, 22, 29, and 30 shortly after noon,” but “These were short-lived.” [National Institute of Standards and Technology, 11/2008, pp. 51] The fires on floors 7 to 9 and 11 to 13, however, “grew and spread, since they were not extinguished either by the automatic sprinkler system or by [the New York City Fire Department], because water was not available in WTC 7.” Fires are “generally concentrated on the east and north sides of the northeast region beginning at about 3 p.m. to 4 p.m.” [National Institute of Standards and Technology, 11/2008, pp. 21] The fires on floors 7 to 9 and 11 to 13 have “characteristics similar to those that have occurred previously in tall buildings,” according to NIST, and “Their growth and spread [are] consistent with ordinary building contents fires.” [National Institute of Standards and Technology, 11/2008, pp. xxxvi] These fires are “fed by combustibles (e.g., desks, chairs, papers, carpet) that were ordinary for commercial occupancies.” However, NIST will point out, there is “no evidence that the fires spread from floor to floor, except, perhaps, just prior to the collapse of the building.” [National Institute of Standards and Technology, 11/2008, pp. 51-52]
Limited Evidence Available - Both FEMA and NIST will admit that their accounts of the fires in WTC 7 are based upon imperfect evidence. In its report on the WTC collapses, published in May 2002, FEMA will note, “Currently, there is limited information about the ignition and development of fires at WTC 7.” [Federal Emergency Management Agency, 5/1/2002, pp. 5-20] In the final report of its investigation of the collapse of WTC 7, NIST will point out that “available images showing fires in WTC 7 did not allow the detailed description of fire spread that was possible for the WTC towers.” The report will add: “It must be kept in mind that [NIST’s] fire observations were based on images of the exterior faces, which provided little indication about the behavior of fires well removed from the exterior walls. It is likely that much of the burning took place beyond the views of the windows.” But, the report will state, “[T]here was sufficient information to derive general descriptions of fire ignition and spread on various floors of the building.” [National Institute of Standards and Technology, 11/2008, pp. 18]
NIST Blames Fires for Collapse - WTC 7 collapses at 5:20 p.m. this afternoon (see (5:20 p.m.) September 11, 2001). In late 2008, at the end of its investigation into WTC 7’s collapse, NIST will blame the fires WTC 7 suffers for causing its collapse (see August 21, 2008 and August 21, 2008). NIST will state: “The heat from the uncontrolled fires caused steel floor beams and girders to thermally expand, leading to a chain of events that caused a key structural column to fail. The failure of this structural column then initiated a fire-induced progressive collapse of the entire building.” [National Institute of Standards and Technology, 8/21/2008; National Institute of Standards and Technology, 11/2008, pp. xxxvi-xxxvii] However, critics will dispute this conclusion, instead blaming explosives for the collapse (see August 21, 2008). [New York Times, 8/21/2008] FEMA will offer no firm conclusions about the possible role fires play in causing WTC 7 to collapse. In its 2002 report it will state, “The specifics of the fires in WTC 7 and how they caused the building to collapse remain unknown at this time.” [Federal Emergency Management Agency, 5/1/2002, pp. 5-31]

According to Captain Michael Currid, the sergeant at arms for the Uniformed Fire Officers Association, some time after the collapse of the North Tower, he sees four or five fire companies trying to extinguish fires in Building 7 of the WTC. Someone from the city’s Office of Emergency Management tells him that WTC 7 is in serious danger of collapse. Currid says, “The consensus was that it was basically a lost cause and we should not lose anyone else trying to save it.” Along with some others, he goes inside WTC 7 and yells up the stairwells to the fire fighters, “Drop everything and get out!” [Murphy, 2002, pp. 175-176] However, other accounts contradict this, claiming that no attempt is made to fight the fires in WTC 7 (see (11:30 a.m.) September 11, 2001). One report later claims, “Given the limited water supply and the first strategic priority, which was to search for survivors in the rubble, FDNY did not fight the fires [in WTC 7].” [Fire Engineering, 9/2002] And a 2002 government report says, “the firefighters made the decision fairly early on not to attempt to fight the fires, due in part to the damage to WTC 7 from the collapsing towers.” [Federal Emergency Management Agency, 5/1/2002, pp. 5-21] Building 7 eventually collapses late in the afternoon of 9/11 (see (5:20 p.m.) September 11, 2001).

Allan Dodds Frank.Allan Dodds Frank. [Source: CNN]A CNN correspondent incorrectly suggests that a third skyscraper may have recently collapsed in New York. Reporting from Lower Manhattan, Allan Dodds Frank describes: “[J]ust two or three minutes ago there was yet another collapse or explosion. I’m now out of sight, a Good Samaritan has taken me in on Duane Street. But at a quarter to 11, there was another collapse or explosion following the 10:30 collapse of the second tower. And a firefighter who rushed by us estimated that 50 stories went down. The street filled with smoke. It was like a forest fire roaring down a canyon.” [CNN, 9/11/2001] A third tower—the 47-story World Trade Center Building 7—does collapse on this day. It will not come down, however, until 5:20 in the afternoon (see (5:20 p.m.) September 11, 2001). [Washington Post, 9/12/2001; New York Times, 11/29/2001]

The New York Fire Department (FDNY) assigns a chief officer to take charge of operations at WTC Building 7. The chief is initially ordered to put out the fires there. It is determined around this time that there are fires on floors 6-8, 17, 21 and 30. However, there are problems with the water supply: There is no water coming out of the hydrant system nearby, and an FDNY chief officer who has been in WTC 7 says he opened a standpipe on the 4th floor of one stairway, but found no water in the standpipe system. This should not be a problem though, as two or three FDNY fireboats have been tied up on the Hudson shore, specifically to provide water to the site, and lines are already being stretched up to the WTC area. However, as the National Institute of Standards and Technology (NIST) will later report, “According to the FDNY first-person interviews, water was never an issue at WTC 7 since firefighting was never started in the building. When the Chief Officer in charge of WTC 7 got to Barclay Street and West Broadway, numerous firefighters and officers were coming out of WTC 7. These firefighters indicated that several blocks needed to be cleared around WTC 7 because they thought that the building was going to collapse.” [Firehouse (.com), 9/17/2001; Time Out New York, 9/27/2001; National Institute of Standards and Technology, 9/2005, pp. 110-111] However, one fire captain later claims to have seen numerous firefighters trying to extinguish fires in WTC 7 at some unspecified time after the North Tower collapsed, until they were instructed to stop doing so (see After 10:28 a.m. September 11, 2001).

Jeffrey Scott Shapiro.Jeffrey Scott Shapiro. [Source: University of Florida]Larry Silverstein, who recently took over the lease of the World Trade Center complex (see July 24, 2001), discusses possibly bringing down WTC Building 7 in a controlled demolition in a telephone conversation with his insurance carrier, according to a reporter who is at the WTC site this afternoon. [Fox News, 4/22/2010] WTC 7 is a 47-story office building located just north of the Twin Towers. The National Institute of Standards and Technology (NIST) will say it suffered some structural damage (see 10:28 a.m. September 11, 2001) when the North Tower collapsed (see 10:28 a.m. September 11, 2001) and it has fires on several floors (see (10:28 a.m.-5:20 p.m.) September 11, 2001). It will collapse at 5:20 p.m., apparently becoming the first tall building ever to come down primarily as a result of fire (see (5:20 p.m.) September 11, 2001). [National Institute of Standards and Technology, 11/2008, pp. xxxv-xxxvi]
Silverstein Allegedly Wants WTC 7 Demolished - Investigative reporter Jeffrey Scott Shapiro, who is at the scene of the attacks in New York, will later recall: “Shortly before [WTC 7] collapsed, several NYPD officers and Con Edison workers told me that Larry Silverstein… was on the phone with his insurance carrier to see if they would authorize the controlled demolition of the building, since its foundation was already unstable and expected to fall. A controlled demolition would have minimized the damage caused by the building’s imminent collapse and potentially save lives.” Shapiro will add: “Many law enforcement personnel, firefighters, and other journalists were aware of this possible option. There was no secret.” [Fox News, 4/22/2010] Preparing a large building for demolition usually takes weeks, or even months. This time is spent on operations such as wrapping concrete columns to ensure pieces do not fly off. [Baltimore Sun, 2/26/1995; PBS NOVA, 12/1996; Construction Equipment Guide, 2/24/2005]
Discussion of Demolition Later Denied - Silverstein will later recall discussing WTC 7 over the phone with the commander of the New York Fire Department, and telling him, “We’ve had such terrible loss of life, maybe the smartest thing to do is pull it” (see After 12:00 Noon September 11, 2001), but a spokesman will subsequently claim that Silverstein was referring to withdrawing firefighters from the building, not bringing WTC 7 down with explosives. [US Department of State, 9/16/2005; BBC, 7/4/2008] At the end of a three-year investigation into the building’s collapse, NIST will say WTC 7 “did not collapse from explosives,” but critics will dispute this conclusion (see August 21, 2008).

At some point during the afternoon of 9/11, WTC leaseholder Larry Silverstein receives a phone call from the Fire Department commander, where they discuss the state of Building 7 of the WTC complex. Silverstein will discuss this call in a PBS documentary broadcast in 2002, saying that he told the commander, “You know, we’ve had such terrible loss of life, maybe the smartest thing to do is pull it. And they made that decision to pull and then we watched the building collapse.” [PBS, 9/10/2002] Some people suggest that by “pull it” Silverstein meant the deliberate demolition of the building. But a spokesman for Silverstein states that he was expressing “his view that the most important thing was to protect the safety of those firefighters, including, if necessary, to have them withdraw from the building.” [US Department of State, 9/16/2005] Yet this claim is contradicted by some accounts, according to which firefighters decided early on not to attempt fighting the fires in WTC 7 (see After 10:28 a.m. September 11, 2001)(see (11:30 a.m.) September 11, 2001). According to Haaretz, “In the afternoon of September 11, the Fire Department informed him that the smaller 7 World Trade Center building, which he owned, was going to collapse.” [Ha'aretz, 11/21/2001] Building 7 eventually collapses at around 5:20 in the afternoon (see (5:20 p.m.) September 11, 2001).

Barry Jennings, a City Housing Authority worker who had become trapped in World Trade Center Building 7, finds the building’s lobby in ruins as he is being rescued from it, and steps over what feels to him like dead bodies. [Dylan Avery, 2007] After the first plane hit the WTC, Jennings had gone up to the emergency command center on the 23rd floor of WTC 7 along with Michael Hess, New York’s corporation counsel (see (Shortly Before 9:03 a.m.) September 11, 2001). [Associated Press, 9/11/2001; Dylan Avery, 2007] After heading down the stairs, the two men became trapped on the building’s eighth floor (see (Between 9:15 a.m. and 12:00 p.m.) September 11, 2001). Some time later, firefighters come into WTC 7 to help the two men out of the building. [UPN 9, 9/11/2001; National Institute of Standards and Technology, 9/2005, pp. 109-110]
Lobby Is 'Total Ruins' - According to Jennings, when he gets down to the lobby, he is astonished to find it totally ruined. In a 2007 interview he will recall: “[W]hen I came in there, the lobby had nice escalators. It was a huge lobby.” But reaching it again, he asks the firefighter who is escorting him, “Where are we?” and the firefighter answers, “This was the lobby.” Jennings finds this “unbelievable,” and says, “You gotta be kidding me.” He will describe the lobby as being “total ruins.”
'Stepping over People' - Furthermore, Jennings steps over what may be dead bodies in the lobby. He will say: “[T]he firefighter that took us down kept saying, ‘Do not look down,’ and I kept saying, ‘Why is that?’ [He said,] ‘Do not look down.’ And, stepping over people. And you know you could feel when you’re stepping over people.” [Dylan Avery, 2007] Yet most people were evacuated from WTC 7 around 9:03 a.m., if not earlier (see (9:03 a.m.) September 11, 2001). [National Institute of Standards and Technology, 9/2005, pp. 109] The very latest that people left the building, according to official accounts, was 9:30 a.m. (see (9:30 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 305] In a later interview, Jennings will clarify: “I never saw dead bodies.… [I]t felt like I was stepping over them but I never saw them.” The BBC will say, “There is no evidence that anyone died in Tower 7 on 9/11.” [BBC, 7/4/2008; BBC, 7/6/2008] According to the National Institute of Standards and Technology (NIST), firefighters lead Jennings and Hess out of WTC 7 at around 12:10 p.m. to 12:15 p.m. (see 12:10 p.m.-12:15 p.m. September 11, 2001).

[BBC, 7/6/2008; BBC, 10/17/2008] WTC 7 was damaged by the debris when the North Tower of the WTC collapsed at 10:28 a.m. (see 10:28 a.m. September 11, 2001). [National Institute of Standards and Technology, 11/2008, pp. 16] At around 12:30 p.m., according to the BBC, Rotanz and some other officials—whose identities are unstated—go into WTC 7 to see what condition the building is in. “At the time the building wasn’t safe, but we had to make an assessment just the same,” Rotanz will later tell the BBC. He will describe what he observes inside WTC 7, saying: “You could hear the building creak above us. You could hear things fall. You could hear the fire burning. You could see columns just hanging from the floors, gaping holes in the floors up above us.” He also sees “an elevator car that was blown out of its shaft” and is now “down the hall.” [BBC, 7/6/2008; BBC, 10/17/2008] The elevator car is “30 or 40 feet away from where the elevator shaft once was,” according to another account.

The chief fire officer who has been assigned to take charge of operations at WTC Building 7 meets with his command officer, to discuss the condition of this building and the fire department’s capabilities for controlling the fires in it. A deputy fire chief who has just been in WTC 7, inspecting up to its 7th or 8th floor, reports that there was a lot of fire inside and the stairway was filling with smoke. The fire chiefs discuss the situation and identify the following conditions:
bullet WTC 7 has suffered damage caused by falling debris from the Twin Towers, and they are uncertain about its structural stability.
bullet There are large fires on at least six floors.
bullet They do not have enough equipment available for conducting operations in the building, such as hoses, standpipe kits, and handie-talkies.
bullet There is no water immediately available for fighting the fires. (However, this concern is apparently contradicted by reports that two or three fireboats are moored nearby, specifically to provide water-pumping capacity for the WTC site.)
Therefore, at around 2:30 p.m., fire officers decide to completely abandon WTC 7 and a final order is given to evacuate the site. Firefighters and other emergency workers will be withdrawn from the surrounding area (see (4:30 p.m.) September 11, 2001), and Building 7 collapses later in the afternoon (see (5:20 p.m.) September 11, 2001).

Building 7 of the World Trade Center, located across the street from the Twin Towers, caught fire after the initial attacks on the WTC. [CNN, 9/12/2001] By 4:10 in the afternoon, CNN had reported it being on fire (see 4:10 p.m. September 11, 2001). Subsequently it is reported that WTC 7 is in danger of collapsing or may have already collapsed. At around 4:15 p.m., CNN reports, “We’re getting information that one of the other buildings… Building 7… is on fire and has either collapsed or is collapsing… now we’re told there is a fire there and that the building may collapse as well.” About 12 minutes later, BBC reporter Greg Barrow, who is in New York, appears on the BBC radio channel Five Live and says, “We are hearing reports from local media that another building may have caught light and is in danger of collapse.” He adds, “I’m not sure if it has yet collapsed but the report we have is talking about Building 7.” Around this time, the area around Building 7 is being evacuated, apparently because senior firefighters have determined it is in danger of collapsing (see (4:30 p.m.) September 11, 2001). At 4:53, based on the earlier reports, the Radio Five Live show’s presenter will incorrectly claim that Building 7 has already collapsed, saying, “Twenty-five minutes ago we had reports from Greg Barrow that another large building has collapsed just over an hour ago.” [BBC, 3/2/2007] Starting at 4:54, BBC television will also begin reporting that Building 7 has already collapsed (see 4:54 p.m.-5:10 p.m. September 11, 2001). In fact, it does not do so until 5:20 (see (5:20 p.m.) September 11, 2001).

bullet Firefighter Edward Kennedy says, “I remember [Chief Visconti] screaming about 7, No. 7, that they wanted everybody away from 7 because 7 was definitely going to collapse.” [City of New York, 1/17/2002]
bullet Firefighter Vincent Massa: “They were concerned about seven coming down, and they kept changing us, establishing a collapse zone and backing us up.” [City of New York, 12/4/2001]
bullet Firefighter Tiernach Cassidy: “[B]uilding seven was in eminent collapse. They blew the horns. They said everyone clear the area until we got that last civilian out.” [City of New York, 12/30/2001]
bullet Battalion Fire Chief John Norman: “I was detailed to make sure the collapse zone for 7 WTC had been set up and was being maintained.” [Fire Engineering, 10/2002]
Several New York Fire Department chief officers, who have surveyed Building 7, have apparently determined it is in danger of collapsing. [Fire Engineering, 9/2002] For example, Fire Chief Daniel Nigro explains their decision-making process, saying: “A number of fire officers and companies assessed the damage to the building. The appraisals indicated that the building’s integrity was in serious doubt. I issued the orders to pull back the firefighters and define the collapse zone.” [Fire Engineering, 9/2002] Fire Chief Frank Fellini says, “We were concerned that the fires on several floors and the missing steel would result in the building collapsing.” [City of New York, 12/3/2001] And Fire Captain Ray Goldbach says, “[W]e made a decision to take all of our units out of 7 World Trade Center because there was a potential for collapse.” [City of New York, 10/24/2001] However, some firefighters seem surprised at this decision. When Fire Commissioner Thomas Von Essen is making his way through hundreds of firefighters who are being held away from the WTC site, he hears complaints like, “It could take days for that building to come down,” and, “Why don’t they let us in there?” [Essen, 2002, pp. 45] When Deputy Fire Chief Nick Visconti is instructing firefighters to evacuate the area, one comment he receives is, “[O]h, that building is never coming down, that didn’t get hit by a plane, why isn’t somebody in there putting the fire out?” [Firehouse Magazine, 9/9/2002]

[Source: BBC]Several times, the BBC reports that Building 7 of the World Trade Center has collapsed, when it is in fact still standing. At 4:54 p.m., its domestic television news channel, BBC News 24, reports, “We’re now being told that yet another enormous building has collapsed… it is the 47-story Salomon Brothers building [i.e. WTC 7].” Three minutes later, its international channel, BBC World, reports, “We’ve got some news just coming in actually that the Salomon brothers building in New York right in the heart of Manhattan has also collapsed.” Then, at about 5:10 p.m., BBC World repeats the claim: “I was talking a few moments ago about the Salomon building collapsing and indeed it has… it seems this wasn’t the result of a new attack but because the building had been weakened during this morning’s attack.” Yet WTC 7 does not collapse until 5:20 p.m., over 25 minutes after the BBC first reported it (see (5:20 p.m.) September 11, 2001). The BBC’s live shot even shows the building still standing in the background, while its collapse is being reported. When these reports come to light early in 2007, Richard Porter, the head of news for BBC World, will suggest the error was due to the “confusing and chaotic situation on the ground” on 9/11. [BBC, 3/2/2007] Starting around 4:15 p.m., CNN and other news outlets had been reporting that WTC 7 was in danger of collapsing or may already have collapsed (see (4:15 p.m.-4:27 p.m.) September 11, 2001).

[Source: unknown] (click image to enlarge)Building 7 of the World Trade Center complex, a 47-story tower, collapses. No one is killed. [CNN, 9/12/2001; Washington Post, 9/12/2001; MSNBC, 9/22/2001; Associated Press, 8/21/2002] It collapses in 6.6 seconds, which is just 0.6 of a second longer than it would have taken a free-falling object dropped from its roof to hit the ground. [Deseret Morning News, 11/10/2005] Many questions will arise over the cause of its collapse in the coming months and years. Building 7, which was not hit by an airplane, is the first modern, steel-reinforced high-rise to collapse because of fire. [Chicago Tribune, 11/29/2001; Stanford Report, 12/5/2001; New York Times, 3/2/2002] Some will later suggest that the diesel fuel stored in several tanks on the premises may have contributed to the building’s collapse. The building contained a 6,000-gallon tank between its first and second floors and another four tanks, holding as much as 36,000 gallons, below ground level. There were also three smaller tanks on higher floors. [Chicago Tribune, 11/29/2001; New York Times, 3/2/2002; New York Observer, 3/25/2002; Federal Emergency Management Agency, 5/1/2002, pp. 1-17] However, the cause of the collapse is uncertain. A 2002 government report will conclude: “The specifics of the fires in WTC 7 and how they caused the building to collapse remain unknown at this time. Although the total diesel fuel on the premises contained massive potential energy, the best hypothesis has only a low probability of occurrence.” [Federal Emergency Management Agency, 5/1/2002, pp. 1-17] Some reports indicate that the building may have been deliberately destroyed. Shortly after the collapse, CBS News anchor Dan Rather comments that the collapse is “reminiscent of… when a building was deliberately destroyed by well-placed dynamite to knock it down.” [CBS News, 9/11/2001] And moments after the collapse, MSNBC’s Brian Williams joins David Restuccio, an FDNY lieutenant, by phone to ask him about the collapse. “You guys knew this was coming all day?” asks Williams. Restuccio replies: “We had heard reports that the building was unstable, and that it would eventually need to come down on its own, or it would be taken down. I would imagine it came down on its own.” Restuccio does not explain what he means by “it would be taken down.” [MSNBC, 9/11/2001]

A chunk of hot metal being removed from the North Tower rubble about eight weeks after 9/11. [Source: Frank Silecchia]In the weeks and months after 9/11, numerous individuals report seeing molten metal in the remains of the World Trade Center:
bullet Ken Holden, who is involved with the organizing of demolition, excavation, and debris removal operations at Ground Zero, will later tell the 9/11 Commission, “Underground, it was still so hot that molten metal dripped down the sides of the wall from [WTC] Building 6.” [9/11 Commission, 4/1/2003]
bullet William Langewiesche, the only journalist to have unrestricted access to Ground Zero during the cleanup operation, will describe, “[I]n the early days, the streams of molten metal that leaked from the hot cores and flowed down broken walls inside the foundation hole.” [Langewiesche, 2002, pp. 32]
bullet Leslie Robertson, one of the structural engineers responsible for the design of the WTC, describes fires still burning and molten steel still running 21 days after the attacks. [SEAU News, 10/2001 pdf file]
bullet Alison Geyh, who heads a team of scientists studying the potential health effects of 9/11, reports: “Fires are still actively burning and the smoke is very intense. In some pockets now being uncovered, they are finding molten steel.” [Johns Hopkins Public Health Magazine, 2001]
bullet Ron Burger, a public health advisor who arrives at Ground Zero on September 12, says that “feeling the heat” and “seeing the molten steel” there reminds him of a volcano. [National Environmental Health Association, 9/2003, pp. 40 pdf file]
bullet Paramedic Lee Turner arrives at the World Trade Center site on September 12 as a member of a federal urban search and rescue squad. While at Ground Zero, he goes “down crumpled stairwells to the subway, five levels below ground.” There, he reportedly sees, “in the darkness a distant, pinkish glow—molten metal dripping from a beam.” [US News and World Report, 9/12/2002]
bullet According to a member of New York Air National Guard’s 109th Air Wing, who is at Ground Zero from September 22 to October 6: “One fireman told us that there was still molten steel at the heart of the towers’ remains. Firemen sprayed water to cool the debris down but the heat remained intense enough at the surface to melt their boots.” [National Guard Magazine, 12/2001]
bullet New York firefighters will recall “heat so intense they encountered rivers of molten steel.” [New York Post, 3/3/2004]
bullet As late as five months after the attacks, in February 2002, firefighter Joe O’Toole sees a steel beam being lifted from deep underground at Ground Zero, which, he says, “was dripping from the molten steel.” [Knight Ridder, 5/29/2002]
Steven E. Jones, a physics professor from Utah, will claim this molten metal is “direct evidence for the use of high-temperature explosives, such as thermite,” used to deliberately bring down the WTC towers. [MSNBC, 11/16/2005] He will say that without explosives, a falling building would have “insufficient directed energy to result in melting of large quantities of metal.” [Deseret Morning News, 11/10/2005] There will be no mention whatsoever of the molten metal in the official reports by FEMA, NIST, or the 9/11 Commission. [Federal Emergency Management Agency, 5/1/2002; 9/11 Commission, 7/24/2004; National Institute of Standards and Technology, 9/2005] But Dr. Frank Gayle, who leads the steel forensics aspects of NIST’s investigation of the WTC collapses, will be quoted as saying: “Your gut reaction would be the jet fuel is what made the fire so very intense, a lot of people figured that’s what melted the steel. Indeed it didn’t, the steel did not melt.” [ABC News 7 (New York), 2/7/2004] As well as the reports of molten metal, data collected by NASA in the days after 9/11 finds dozens of “hot spots” (some over 1,300 degrees) at Ground Zero (see September 16-23, 2001).

E Team crisis management software.E Team crisis management software. [Source: Police Magazine]New York City’s Office of Emergency Management (OEM) is much aided in its recovery efforts at Ground Zero when it starts using a little-known piece of emergency management software, which it only purchased last month and that was originally going to be launched on September 17. [Wall Street Journal, 10/23/2001; Wired News, 11/2/2001] The software, called E Team, helps organizations to “prepare for, respond to, and recover from disasters and emergencies of all types.” [California Technology Ventures, 10/16/2001] It was created by E Team Inc., a company based in Canoga Park, California. [e-ProWire, 5/22/2002] The New York City OEM only bought E Team in August (see August 2001). It installed the software on computers in its Emergency Operations Center in World Trade Center Building 7 (WTC 7) and intended to launch the system on September 17. [Wall Street Journal, 10/23/2001; Wired News, 11/2/2001]
Engineers Put Together New System to Manage Recovery Operation - The OEM was in contact with E Team Inc. executives within a few hours of the attacks on the WTC on September 11. [Wall Street Journal, 10/23/2001; e-ProWire, 5/22/2002] E Team Inc. employees reportedly suspected in advance that WTC 7—which housed the computers on which their software was installed—would collapse. Matt Walton, the company’s CEO, will later recall: “We knew that tower number 7 was probably not going to make it. We contacted the [New York City] mayor’s office and told them we would put up the New York databases on our own servers.” [Wired News, 11/2/2001] That night, a group of E Team Inc. engineers gathered at the company’s headquarters in Canoga Park, and put together a system on the company’s servers using data that the New York City OEM had sent to the company to prepare for the launch of the E Team system on September 17. By September 12, the engineers had the system ready for use. [Wall Street Journal, 10/23/2001]
System Goes into Operation at New Command Center - For the first couple of days after 9/11, the OEM had to coordinate its recovery efforts on paper or using e-mail, because its emergency management computer systems were destroyed when WTC 7 collapsed on the afternoon of September 11 (see (5:20 p.m.) September 11, 2001). An OEM spokesman will comment, “It became apparent that we needed very sophisticated technology to effectively handle the crisis.” [Wired News, 11/2/2001] Then, on September 14, the E Team system goes into operation at the OEM’s temporary command center at Pier 92 on the Hudson River, where several server computers have been set up to run the software and 200 workstations are connected to the system. [Wall Street Journal, 10/23/2001; e-ProWire, 5/22/2002] Troy Armstrong and John Hughes, two senior E Team Inc. employees who are distinguished emergency management professionals, are installed at the temporary command center. They are supplemented with three additional E Team Inc. employees.
System Plays Key Role in Recovery Operation - The main initial uses of E Team in response to the 9/11 attacks are resource management and situation reporting, but over time the system will also be used for incident reporting, asset tracking, action planning, and logistics. [California Technology Ventures, 10/16/2001] E Team tracks everything related to the recovery efforts at Ground Zero. It enables emergency responders to monitor the location of fires, personnel, supplies, and trucks. It also handles resource requests. [Wired News, 11/2/2001; e-ProWire, 5/22/2002] It makes the recovery operation “much more efficient,” according to Lieutenant Colonel John Flanagan of the New York Army National Guard. [Wall Street Journal, 10/23/2001] In total, more than 1,700 individuals from over 200 organizations will use the E Team system at the height of the rescue and recovery efforts.

[Source: USGS]In response to requests from the Environmental Protection Agency, through the US Geological Survey, NASA flies a plane over the site of the WTC complex, equipped with a remote sensing instrument called AVIRIS. AVIRIS is able to remotely record the near-infrared signature of heat. Analysis of the data it collects indicates temperatures at Ground Zero of above 800 degrees Fahrenheit, with some areas above 1,300 degrees. On September 16, dozens of “hot spots” are seen, but by September 23, only four or five remain. [US Geological Survey, 11/27/2001; US Geological Survey, 10/2002 pdf file] Robert Shaler, the scientist who leads the forensic examination by the New York City medical examiner’s office to identify 9/11 victims, later will state that the “DNA in the bodies” of WTC victims “was in pretty bad shape. These bones were exposed to extreme temperatures.” [US News and World Report, 12/5/2005] Don Carson, a hazardous materials expert, later will say, “There are pieces of steel being pulled out [of the WTC rubble] that are still cherry red. It’s like the charcoal that you put in your grill.… You light it and it stays hot.” [New York Daily News, 11/1/2001] And Dr. Jonathan Barnett, a member of FEMA’s WTC investigation team, will describe steel members in the debris pile that appear to have been partly evaporated in extremely high temperatures. [New York Times, 11/29/2001] Despite the WTC rubble being pumped with an almost constant jet of water, eventually totaling thousands of gallons, almost 12 weeks after 9/11 at least one fire is still burning, making it the longest-burning structural fire in history. [New Scientist, 12/3/2001; CBS News, 12/19/2001] As well as the hot spots, numerous witnesses describe molten metal being found at Ground Zero (see September 12, 2001-February 2002).

Dr. Abolhassan Astaneh-Asl is a professor of civil and environmental engineering at the University of California, Berkeley. He specializes in studying structural damage done by earthquakes and terrorist bombings. [Chronicle of Higher Education, 12/7/2001; CBS News, 3/11/2002] He arrives in New York on September 19 to conduct a two-week scientific reconnaissance of the collapsed towers, hoping to gain an understanding of how they had come down. His project is one of eight financed by the National Science Foundation to study the WTC disaster. [New York Times, 10/2/2001; Berkeleyan, 10/3/2001; US Congress. House. Committee on Science, 3/6/2002] He examines numerous pieces of steel taken from Ground Zero. [Chronicle of Higher Education, 12/7/2001] Astaneh-Asl will describe the WTC as “the best-designed building I have ever seen.” [San Francisco Chronicle, 10/22/2001] Yet he notices unusual warping and other damage in its remaining steel:
bullet At a recycling center in New Jersey, he sees 10-ton steel beams from the towers that look “like giant sticks of twisted licorice.” [Chronicle of Higher Education, 12/7/2001] He shows the San Francisco Chronicle a “banana-shaped, rust-colored piece of steel” that has “twisted like toffee during the terrorist attack.” [San Francisco Chronicle, 10/22/2001]
bullet He later recalls, “I saw melting of girders in [the] World Trade Center.” [PBS, 5/10/2007]
bullet He notes that steel has bent at several connection points that had joined the floors of the WTC to the vertical columns. He describes the connections as being smoothly warped, saying, “If you remember the Salvador Dali paintings with the clocks that are kind of melted—it’s kind of like that.” He adds, “That could only happen if you get steel yellow hot or white hot—perhaps around 2,000 degrees.” [Chronicle of Higher Education, 12/7/2001]
bullet Astaneh-Asl says that steel flanges have been reduced “from an inch thick to paper thin.” [Berkeleyan, 10/3/2001]
bullet He finds a foot-long twisted shard of steel that is “like a piece of bread, but it was high-strength steel.” He comments, “I haven’t seen anything like this [before].” [Berkeley Daily Planet, 10/20/2001]
bullet He finds “severely scorched [steel] members from 40 or so floors below the points of impact [by the planes].” He believes this is the result of the planes having destroyed the elevator walls, thereby allowing burning jet fuel to pour down into the building, igniting fires hundreds of feet below the impact floors. [CBS News, 3/12/2002]
bullet He says that, in some places, the fireproofing used to protect the WTC steel has “melted into a glassy residue.” [New York Times, 10/2/2001]
bullet Astaneh-Asl sees a charred I-beam from WTC Building 7, which collapsed late in the afternoon of 9/11. “The beam, so named because its cross-section looks like a capital I, had clearly endured searing temperatures. Parts of the flat top of the I, once five-eighths of an inch thick, had vaporized.” [New York Times, 10/2/2001]
Other individuals will report seeing molten metal in the remains of the World Trade Center in the weeks and months after 9/11 (see September 12, 2001-February 2002), and data collected by NASA reveals dozens of “hot spots” (some over 1,300 degrees Fahrenheit) at Ground Zero (see September 16-23, 2001). But Thomas Eagar—an engineering professor at the Massachusetts Institute of Technology—later comments that the “temperature of the fire at the WTC [on 9/11] was not unusual, and it was most definitely not capable of melting steel.” [Eagar and Musso, 12/2001] Yet Astaneh-Asl will later put forward the “tentative” conclusion, “The collapse of the [Twin Towers] was most likely due to the intense fire initiated by the jet fuel of the planes and continued due to burning of the building contents.” [Astaneh-Asl, 11/30/2003 pdf file] Astaneh-Asl is a member of the team assembled by the American Society of Civil Engineers to investigate the World Trade Center site after 9/11 (see September 12, 2001), though he will resign from this because he disagrees with its decision to keep findings secret until the initial inquiry has been completed.

[Source: US Department of Defense]A conversation between Osama bin Laden, Ayman al-Zawahiri, al-Qaeda spokesman Suliman abu Ghaith, and Khaled al-Harbi, a veteran of al-Qaeda’s jihad in Bosnia, is videotaped. A portion of the taped conversation is later said to be found by the US and will be used as evidence of bin Laden’s involvement in 9/11. [Unknown, 2001; Guardian, 12/13/2001; Kohlmann, 2004, pp. 28-9] According to a translation released by the Pentagon, the man said to be bin Laden says: “[W]e calculated in advance the number of casualties from the enemy, who would be killed based on the position of the tower. We calculated that the floors that would be hit would be three or four floors. I was the most optimistic of them all… (inaudible)… due to my experience in this field, I was thinking that the fire from the gas in the plane would melt the iron structure of the building and collapse the area where the plane hit and all the floors above it only. This is what we had hoped for.” He continues: “We had notification since the previous Thursday that the event would take place that day. We had finished our work that day and had the radio on. It was 5:30 p.m. our time.… Immediately, we heard the news that a plane had hit the World Trade Center. We turned the radio station to the news from Washington.… At the end of the newscast, they reported that a plane just hit the World Trade Center.… After a little while, they announced that another plane had hit the World Trade Center. The brothers who heard the news were overjoyed by it.” [US Department of Defense, 12/13/2001 pdf file] The release of the tape, which is said to be found by US intelligence officers in Jalalabad, will be a major news story, and the tape will be taken by the media as proof of bin Laden’s responsibility for 9/11. President Bush will comment, “For those who see this tape, they’ll realize that not only is he guilty of incredible murder, he has no conscience and no soul, that he represents the worst of civilization.” British Foreign Secretary Jack Straw will add, “By boasting about his involvement in the evil attacks, bin Laden confirms his guilt.” [BBC, 12/14/2001; Fox News, 12/14/2001; CNN, 12/16/2001] However, the tape will later be disputed from three points of view:
bullet The accuracy of the translation will be questioned (see December 20, 2001). For example, the man thought to be bin Laden does not say “we calculated in advance the number of casualties,” but “we calculated the number of casualties”;
bullet An analyst will conclude that the tape was actually made earlier as a part of a US-run sting operation (see (September 26, 2001));
bullet Some commentators will question whether the person in the video is actually bin Laden (see December 13, 2001).
In mid-2002, Al Jazeera reporter Yosri Fouda will allegedly interview al-Qaeda figures Ramzi bin al-Shibh and Khalid Shaikh Mohammed (see April, June, or August 2002). In a 2003 book he will co-write, Fouda will claim that he asked an unnamed al-Qaeda operative who was setting up the interview if the bin Laden video was fake. This person will supposedly reply: “No. The tape, the brothers said—I am not sure whether they left it behind or not—but the Sheikh [bin Laden], yes, was talking to someone from Mecca.” [Fouda and Fielding, 2003, pp. 135]

A sample of WTC steel eroded and corroded due to eutectic formations.A sample of WTC steel eroded and corroded due to eutectic formations. [Source: FEMA]The Journal of the Minerals, Metals and Materials Society (JOM) reports that the examination of a beam from the remains of WTC Building 7—which collapsed late in the afternoon of 9/11 (see (5:20 p.m.) September 11, 2001)—has revealed “unexpected erosion” of the steel. The article states: “The formation of the eutectic mixture of iron oxide and iron sulfide lowers the temperature at which liquid can form in this steel. This strongly suggests that the temperatures in this region of the steel beam approached around 1,000°C, forming the eutectic liquid by a process similar to making a ‘blacksmith’s weld’ in a hand forge.” [Barnett, Biederman, and Sisson, 12/2001] The New York Times will call this “perhaps the deepest mystery uncovered in the investigation.” [New York Times, 2/2/2002] FEMA’s World Trade Center Building Performance Study, released in May 2002 (see May 1, 2002), will add that the same “unusual erosion patterns” have been observed in a sample of the remaining structural steel from one of the Twin Towers. It will state, “This sulfur-rich liquid penetrated preferentially down grain boundaries of the steel, severely weakening the beam and making it susceptible to erosion.” FEMA is unable to explain this phenomenon, saying, “The severe corrosion and subsequent erosion… are a very unusual event. No clear explanation for the source of the sulfur has been identified.… It is possible that this is the result of long-term heating in the ground following the collapse of the buildings. It is also possible that the phenomenon started prior to collapse and accelerated the weakening of the steel structure.” [Federal Emergency Management Agency, 5/1/2002, pp. C-1 - C-13] Despite FEMA’s call for further research, the National Institute of Standards and Technology (NIST) will make no mention of the eutectic formations in its final report into the WTC collapses, released in late 2005, following its three-year investigation.

The picture on the right is undisputendly bin Laden in DecemberThe man in the picture on the left is supposed to be bin Laden in October 2001. The picture on the right is undisputendly bin Laden in December [Source: Reuters]Following the release of a home video in which Osama bin Laden apparently confesses to involvement in 9/11 (see Mid-November 2001), some commentators question its authenticity, as a number of strange facts about the video soon emerge. For example, all previous videos had been made with the consent of bin Laden, and usually released to the Arabic television channel Al Jazeera. This video was supposedly recorded without his knowledge, found in a house in Afghanistan, and then passed to the CIA by an unknown person or group. Experts point out that it would be possible to fake such a video. So many people doubt the video’s authenticity that President Bush soon makes a statement, saying it was “preposterous for anybody to think this tape was doctored. Those who contend it’s a farce or a fake are hoping for the best about an evil man.” [Guardian, 12/15/2001] Some commentators will suggest that the person thought to be bin Laden is not actually the al-Qaeda leader. For example, arabist Kevin Barrett will say that the person in the video is “at least 40 or 50 pounds heavier, and his facial features [are] obviously different.” [Capital Times (Madison), 2/14/2006] The man said to be bin Laden also makes some questionable statements in the video:
bullet “I was thinking that the fire from the gas in the plane would melt the iron structure of the building…” [US Department of Defense, 12/13/2001 pdf file] The jet fuel spilled from the planes burned up about 10 minutes after impact (see 8:57 a.m. September 11, 2001), the towers’ structure did not melt (see September 12, 2001-February 2002), and the towers were not made of iron, but steel. [National Institute of Standards and Technology, 9/2005, pp. 6] Bin Laden had studied civil engineering at university and had experience as a construction contractor. [Burke, 2004, pp. 47; Laden, 2005, pp. xii-xiii] It is unclear why he would think the towers were made of iron.
bullet “We did not reveal the operation to [the brothers who conducted the operation] until they are there and just before they boarded the planes.” [US Department of Defense, 12/13/2001 pdf file] All the hijackers purchased tickets for the 9/11 flights about two weeks in advance (see August 25-September 5, 2001).

World Trade Center Building 7, which collapsed late in the afternoon of 9/11, had contained two independently supplied and operated fuel systems for emergency power. The fuel had been in several storage tanks low down in the building. In March and April, two 11,700-gallon tanks that had been located under the building’s first floor loading dock and operated by Silverstein Properties are removed from the collapse site. They show no evidence of fuel leakage. FEMA says that approximately 20,000 gallons of fuel are subsequently recovered from them, which is about 85 percent of their total capacity. In early May, two 6,000-gallon tanks that had been owned by Salomon Smith Barney and were also located below the loading dock are recovered. These were always kept full for emergencies and would have been full on 9/11. Yet now they are damaged and appear to be empty. According to the National Institute of Standards and Technology (NIST), “Some fuel contamination was found in the gravel below the tanks and sand below the slab on which the tanks were mounted, but no contamination was found in the organic marine silt/clay layer underneath.” Shyam Sunder, lead investigator of NIST’s WTC investigation, will state that this “suggests that this fuel… could have been consumed in the building.” This finding “allows for the possibility, though not conclusively, that the fuel may have contributed to a fire on Floor 5” of WTC 7. [Federal Emergency Management Agency, 5/1/2002, pp. 5-15; Associated Press, 6/6/2002; Newsday, 6/6/2002; National Institute of Standards and Technology, 4/5/2005 pdf file; New York City Council, 9/8/2006 pdf file] Some people have speculated that the diesel fuel stored in WTC 7 may have played a role in its collapse (see March 2, 2002). However, FEMA says, “Although the total diesel fuel on the premises contained massive potential energy, the best hypothesis has only a low probability of occurrence.” WTC 7 housed another 6,000-gallon tank between its second and third floors, which was meant to fuel generators that would supply backup power to the mayor’s 23rd-floor emergency command center (see June 8, 1999). Currently, no data are available on the condition of this tank. [Federal Emergency Management Agency, 5/1/2002, pp. 5-16 and 5-31]

A New York Times article theorizes that diesel fuel tanks were responsible for the collapse of Building 7 of the WTC. It collapsed at 5:20 p.m. on 9/11, even though it was farther away from the Twin Towers than many other buildings that remained standing (see (5:20 p.m.) September 11, 2001). It was the first time a steel-reinforced high-rise in the US had ever collapsed in a fire. One of the fuel tanks had been installed in 1999 (see June 8, 1999) as part of a new “Command Center” for Mayor Rudolph Giuliani. [New York Times, 3/2/2002; Dow Jones Business News, 9/10/2002] However, in interviews, several Fire Department officers who were on the scene say they were not aware of any combustible liquid pool fires in WTC 7. [Fire Engineering, 9/2002] And, according to the National Institute of Standards and Technology (NIST), between 11:30 a.m. and 2:30 p.m. on 9/11, “No diesel smells [were] reported from the exterior, stairwells, or lobby areas” of WTC 7. [National Institute of Standards and Technology, 6/2004, pp. L-22] Curiously, given all the Wall Street scandals later in the year, Building 7 housed the SEC files related to numerous Wall Street investigations, as well as other federal investigative files. All the files for approximately 3,000 to 4,000 SEC cases were destroyed. Some were backed up in other places, but many were not, especially those classified as confidential. [New York Law Journal, 9/17/2001] Lost files include documents that could show the relationship between Citigroup and the WorldCom bankruptcy. [Street, 8/9/2002] The Equal Employment Opportunity Commission estimates over 10,000 cases will be affected. [New York Law Journal, 9/14/2001] The Secret Service had its largest field office, with more than 200 employees, in WTC 7 and also lost investigative files. Says one agent: “All the evidence that we stored at 7 World Trade, in all our cases, went down with the building.” [Tech TV, 7/23/2002] The IRS and Department of Defense were also tenants, along with the CIA, which, it has been revealed, had a secret office in Building 7.

A structural engineer who was a member of the team assembled by the American Society of Civil Engineers to investigate the World Trade Center site after 9/11 complains about the decision to rapidly destroy the remaining structural steel from the collapsed WTC buildings. Dr. Abolhassan Astaneh-Asl is a professor of civil and environmental engineering at the University of California at Berkeley, and specializes in studying structural damage done by earthquakes and terrorist bombings. [Chronicle of Higher Education, 12/7/2001; CBS News, 3/11/2002; Associated Press, 9/6/2002] He had come to New York a week after 9/11 to examine the collapsed towers, hoping to gain an understanding of how they had come down (see September 19-October 2001). [New York Times, 10/2/2001; US Congress. House. Committee on Science, 3/6/2002] However, New York City officials had decided early on to quickly transport the remaining structural steel to scrap yards, to be shipped abroad and melted down for reuse (see Shortly After September 11, 2001). As CBS News now reports, “As a result, Astaneh has almost certainly missed seeing crucial pieces before they were cut up and sent overseas.” Astaneh-Asl complains: “When there is a car accident and two people are killed, you keep the car until the trial is over. If a plane crashes, not only do you keep the plane, but you assemble all the pieces, take it to a hangar, and put it together. That’s only for 200, 300 people, when they die. In this case you had 3,000 people dead.” He says: “My wish was that we had spent whatever it takes, maybe $50 million, $100 million, and maybe two years, get all this steel, carry it to a lot. Instead of recycling it, put it horizontally, and assemble it. You have maybe 200 engineers, not just myself running around trying to figure out what’s going on. After all, this is a crime scene and you have to figure out exactly what happened for this crime, and learn from it.” However, he adds, “My wish is not what happens.” [CBS News, 3/12/2002] Astaneh-Asl previously told the New York Times that the scrap steel from the WTC was “worth only a few million dollars, a tiny fraction of the billions of dollars the cleanup will cost.” Yet the knowledge that could be gained from it “could save lives in a future disaster.” [New York Times, 10/2/2001]

The National Institute of Standards and Technology (NIST)—an agency of the US Commerce Department’s Technology Administration—announces details of its forthcoming investigation into the collapses of the World Trade Center Twin Towers and Building 7 on 9/11. The NIST investigation aims “to investigate the building construction, the materials used, and the technical conditions that contributed to the outcome of the World Trade Center (WTC) disaster.” It also aims to examine the activities of building occupants and emergency responders on 9/11, studying such issues as emergency communications within the WTC, the movement of people during the evacuations, and issues around persons with disabilities. Leading technical experts from industry, academia, and other laboratories, alongside NIST’s own expert staff, will participate in the investigation. Expert professionals from the private sector will also be involved. Glenn Corbett, a fire science professor at John Jay College, says, “This is going to be the most extensive building disaster investigation ever performed.” [Associated Press, 8/21/2002; National Institute of Standards and Technology, 8/21/2002; National Institute of Standards and Technology, 8/3/2005] The investigation is formally authorized in October 2002, when the National Construction Safety Team Act is signed into law. The act, which gives NIST authorization to investigate major building failures in the US, is written largely as a result of the World Trade Center collapses. [National Institute of Standards and Technology, 10/2/2002; New York Times, 5/8/2003] NIST’s investigation is originally proposed to last two years, with a budget of $16 million. [National Institute of Standards and Technology, 8/21/2002] However, it eventually will last three years, with its final report into the collapses of the Twin Towers being released in October 2005 (see October 26, 2005). A previous analysis of the WTC collapses conducted by FEMA and the American Society of Civil Engineers (ASCE) was completed earlier in 2002 (see May 1, 2002), but this had a budget of just $1.1 million. By the time NIST starts its investigation, much of the crucial steel debris from the WTC collapses has already been destroyed (see September 12-October 2001). They later refer to there being a “scarcity of physical evidence that is typically available in place for reconstruction of a disaster.” [National Institute of Standards and Technology, 9/2005, pp. xxxvi]

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).

Insulated trusses in the World Trade Center. [Source: Gilsanz Murray Steficek]At a press briefing in New York City, the National Institute of Standards and Technology (NIST) releases a 122-page progress report on its investigation into the WTC collapses. NIST began its study in August 2002 (see August 21, 2002). Investigators say they believe that the Port Authority of New York and New Jersey, who built the Twin Towers, failed to carry out vital tests to establish how the buildings would cope with a major fire. They have been unable to find evidence that tests were conducted on the fireproofing material used in the buildings. Their report also states that in 1969, builders directed contractors to coat the WTC floor supports with half an inch of spray-on fireproofing. In 1999, the Port Authority issued guidelines to triple the thickness of the fireproofing, and by 9/11, about 30 floors in the upper areas of the two towers had been upgraded. Almost all the floors in the impact zone of the North Tower had their fireproofing upgraded, while in the South Tower just the 78th floor—the lowest in its impact zone—had been upgraded. As the New York Times states, though, “investigators took great care… to say they were nowhere close to definitively determining how and why the towers collapsed after they were struck by hijacked airliners.” [National Institute of Standards and Technology, 5/2003, pp. 81; National Institute of Standards and Technology, 5/7/2003; Guardian, 5/8/2003; New York Times, 5/8/2003]

The National Institute of Standards and Technology (NIST) issues a progress report on its investigation into the World Trade Center collapses. Since 2002, NIST has been investigating the collapses of the Twin Towers and WTC Building 7 (see August 21, 2002). The progress report includes its “working hypothesis” for the collapse of WTC 7. This was a 47-story building, located about 350 feet from the north side of WTC 1, which collapsed completely at around 5:20 in the afternoon of 9/11. The report claims that “fire appears to have played a key role” in the collapse, though it points out, “No fire was observed or reported in the afternoon on floors 1-5, 10, or above Floor 13.” It also says, “there may have been some physical damage on the south side of the building.” NIST summarizes its working hypothesis of the WTC 7 collapse as follows:
bullet “An initial local failure at the lower floors (below Floor 13) of the building due to fire and/or debris induced structural damage of a critical column (the initiating event), which supported a large span floor bay with an area of about 2,000 square feet.”
bullet “Vertical progression of the initial local failure up to the east penthouse, as large floor bays were unable to redistribute the loads, bringing down the interior structure below the east penthouse.”
bullet “Horizontal progression of the failure across the lower floors… triggered by damage due to the vertical failure, resulting in the disproportionate collapse of the entire structure.”
NIST claims this hypothesis “is consistent with all evidence currently held by NIST, including photographs and videos, eyewitness accounts and emergency communication records,” but says it “will be revised and updated as results of ongoing, more comprehensive analyses become available.” [National Institute of Standards and Technology, 6/2004, pp. L1, L3, L17, L34, L38, L51-L52; National Institute of Standards and Technology, 6/18/2004] NIST will release its final reports on the collapses of the Twin Towers in October 2005 (see October 26, 2005). As of mid-2007, it has yet to release a final report on the collapse of WTC 7. In early 2006, Dr. S. Shyam Sunder, who is the lead investigator for NIST’s WTC investigation, will admit, “truthfully, I don’t really know” what caused WTC 7 to collapse. He will add, “We’ve had trouble getting a handle on building no. 7” (see March 20, 2006). [New York Magazine, 3/20/2006] An earlier report on the WTC collapses, released by the Federal Emergency Management Agency (FEMA) in May 2002, had been inconclusive on what caused WTC 7 to collapse, and stated that “Further research, investigation, and analyses” were necessary (see May 1, 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).

Based upon its three-year investigation of the WTC collapses, the National Institute of Standards and Technology (NIST) calls for changes in the planning, construction, and operation of skyscrapers. NIST releases 43 draft reports, totaling about 10,000 pages, for public comments. These include 25 pages of recommendations, intended to learn from 9/11 and make building occupants and emergency responders safer in any future disasters. NIST’s inquiry has been conducted by more than 200 technical experts and contractors, and had two main parts: to look at the causes of the collapses and to identify weaknesses in building codes. Their recommendations include specific improvements to building standards, codes and practices; changes to evacuation and emergency response procedures; and research to help prevent future building failures. NIST does not have the authority to change building codes, but hopes to influence the policies of local authorities. The cost of implementing their recommended changes would add an estimated extra 2 to 5 percent to the development costs of buildings. Some are critical of their recommendations. Structural engineer Jon Magnusson, whose firm is the descendant of the company that designed the Twin Towers, says, “They are leading the public down the wrong path. They are saying we are going to fix the codes in order to deal with Sept. 11th. The physics say that you can’t do that.” [New York Times, 6/22/2005; National Institute of Standards and Technology, 6/23/2005; Associated Press, 6/24/2005] The New York Times points out that between 1989 and 1999, only five civilians had been killed in some 6,900 reported high-rise office building fires within the US.

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]

However, the NIST’s account only examines events up to the initiation of each collapse; the investigation “does not actually include the structural behavior of the tower after the conditions for collapse initiation were reached and collapse became inevitable.” [National Institute of Standards and Technology, 9/2005, pp. 82] NIST makes no mention of molten metal found at the collapse site in the weeks and months after 9/11, which has been described in numerous reports (see September 12, 2001-February 2002).

The nationwide telephone survey of 1,200 adults finds that 42 percent of respondents agreed that “the US government and its 9/11 Commission concealed or refused to investigate critical evidence that contradicts their official explanation of the September 11th attacks,” and that “there has been a cover-up.” Ten percent of respondents said they were unsure, while less than half said the government and 9/11 Commission were not covering up. Forty-five percent of respondents felt the 9/11 attacks should be reinvestigated. Forty-four percent believed that President Bush exploited the attacks to justify the 2003 invasion of Iraq. The survey also found that 43 percent of respondents were unaware of the collapse of WTC 7 on 9/11. [Zogby International, 5/24/2006; New York Times, 6/5/2006; Newsday, 9/1/2006] When Lee Hamilton, the former co-chair of the 9/11 Commission, is later questioned about this poll, he will say the figure of 42 percent of Americans believing there has been a cover up is “dispiriting, it’s an unusually high number” (see August 21, 2006). [Canadian Broadcasting Corporation, 8/21/2006] A previous Zogby poll found 49 percent of New York City residents agreed that some leaders “knew in advance” of the 9/11 attacks and “consciously failed to act” (see August 30, 2004).

A poll by Ohio University and Scripps Howard News Service finds that a significant minority of Americans believe there was US government complicity in the 9/11 attacks. Thirty-six percent of the 1,010 respondents say they believe that US government officials “either assisted in the 9/11 attacks or took no action to stop the attacks because they wanted the United States to go to war in the Middle East.” Sixteen percent believe that secretly planted explosives brought down the Twin Towers, and 12 percent believe a military cruise missile, rather than a hijacked aircraft, hit the Pentagon. [Scripps Howard News Service, 8/3/2006; San Francisco Chronicle, 9/3/2006] An earlier poll had found that half of New York City residents believed government officials knew in advance of the attacks and consciously failed to act (see August 30, 2004).

Thomas Kean and Lee Hamilton, the former chairman and vice chairman of the 9/11 Commission, release a book giving a behind-the-scenes look at their 20-month investigation of the September 11 attacks. [Associated Press, 8/4/2006] They begin their book, titled Without Precedent, saying that, because their investigation started late, had a very short time frame, and had inadequate funding, they both felt, from the beginning, that they “were set up to fail.” [Canadian Broadcasting Corporation, 8/21/2006; Rocky Mountain News, 8/25/2006] They explain the difficulties they faced in obtaining certain government documents and describe how the commission almost splintered over whether to investigate the Bush administration’s use of 9/11 as a reason for going to war. It says that if original member Max Cleland—a strong proponent of this line of inquiry—had not resigned (see December 9, 2003), the commission probably would not have reached unanimity. It also calls their gentle questioning of former New York Mayor Rudolph Giuliani during his May 2004 testimony, “a low point” in the commission’s handling of witnesses at its public hearings (see May 19, 2004). [Associated Press, 8/4/2006; New York Daily News, 8/5/2006; New York Times, 8/6/2006] Despite the problems it faced, when discussing his book with the CBC, Hamilton says he thinks the commission has “been reasonably successful in telling the story” of 9/11. [Canadian Broadcasting Corporation, 8/21/2006] Without Precedent, however, contains little new information about the events of 9/11. Intelligence expert James Bamford says there is “an overabundance of self-censorship by the authors.” [New York Times, 8/20/2006]

Former 9/11 Commission co-chair Lee Hamilton.Former 9/11 Commission co-chair Lee Hamilton. [Source: CBC]Lee Hamilton, the former co-chair of the 9/11 Commission, gives a wide-ranging interview to the CBC about Without Precedent, a book he recently co-authored about his time on the 9/11 Commission (see August 15, 2006). In the interview he discusses the various “conspiracy theories” surrounding the events of 9/11. The interviewer, Evan Solomon, mentions to him a recent Zogby poll (see May 17, 2006) that found that 42% of Americans agreed that “the US government, and its 9/11 Commission, concealed or refused to investigate critical evidence that contradicts the official explanation of September 11th.” Hamilton calls this lack of trust in the Commission’s report “dispiriting,” but attacks the “conspiracy theory people,” saying, “when they make an assertion they do it often on very flimsy evidence.” He addresses some of the various “conspiracy theories” that have been put forward about 9/11:
bullet In order to contradict the allegation that the Twin Towers were brought down deliberately with pre-planted explosives, Hamilton says the WTC collapsed (see 8:57 a.m. September 11, 2001) because “the super-heated jet fuel melted the steel super-structure of these buildings and caused their collapse.” He adds, “There’s a powerful lot of evidence to sustain that point of view, including the pictures of the airplanes flying into the building.”
bullet With regard to the collapse of WTC Building 7 (see (5:20 p.m.) September 11, 2001), which some people claim was also caused by explosives, he argues, “[W]e believe that it was the aftershocks of these two huge buildings in the very near vicinity collapsing. And in the Building 7 case, we think that it was a case of flames setting off a fuel container, which started the fire in Building 7, and that was our theory on Building 7.” However, the interviewer points out that the 9/11 Commission’s final report does not actually mention the collapse of Building 7, and Hamilton says he does not recall whether the Commission made a specific decision to leave it out.
bullet In reply to a question about why the debris of Building 7 were moved quickly from the scene without a thorough investigation, even though nobody died in Building 7 and there was no need for rescue operations there, Hamilton responds, “You can’t answer every question when you conduct an investigation.”
bullet When asked whether Saeed Sheikh sent Mohamed Atta $100,000 for the 9/11 plot (see Early August 2001 and Summer 2001 and before), Hamilton replies, “I don’t know anything about it.” When the interviewer presses him about whether the Commission investigated a possible Pakistani Secret Service (ISI) connection to the attacks, Hamilton replies, “They may have; I do not recall us writing anything about it in the report. We may have but I don’t recall it.”
bullet Asked about Secretary of Transportation Norman Mineta’s claim that Vice President Dick Cheney was in the presidential bunker beneath the White House at 9:20 a.m. on 9/11 (see (Between 9:20 a.m. and 9:27 a.m.) September 11, 2001), almost 40 minutes earlier than the Commission claimed he had arrived there, Hamilton replies, “I do not recall.” When pressed, he expands, “Well, we think that Vice President Cheney entered the bunker shortly before 10 o’clock. And there is a gap of several minutes there, where we do not really know what the Vice President really did. There is the famous phone call between the President and the Vice President. We could find no documentary evidence of that phone call.”
bullet When the interviewer points out that Richard Clarke’s account conflicts with the Commission’s over what time authorization was received from Dick Cheney to shoot down Flight 93 (see (Between 9:45 a.m. and 9:56 a.m.) September 11, 2001 and (Between 10:00 a.m. and 10:15 a.m.) September 11, 2001), Hamilton retorts, “Look, you’ve obviously gone through the report with a fine-toothed comb, you’re raising a lot of questions—I can do the same thing.”
The interviewer also asks Hamilton whether he has any unanswered questions of his own about 9/11. Hamilton’s response is: “I could never figure out why these 19 fellas did what they did. We looked into their backgrounds. In one or two cases, they were apparently happy, well-adjusted, not particularly religious - in one case quite well-to-do, had a girlfriend. We just couldn’t figure out why he did it. I still don’t know.” [Canadian Broadcasting Corporation, 8/21/2006]

One of the ‘puffs of smoke’ observed during the Twin Towers collapses.One of the ‘puffs of smoke’ observed during the Twin Towers collapses. [Source: Richard Lethin]The National Institute of Standards and Technology (NIST) issues a seven-page fact sheet to counter alternative theories about the WTC collapses. NIST conducted a three-year study of the collapses, and concluded they were caused by the damage when the planes hit combined with the effects of the ensuing fires. However, many people—what the New York Times calls an “angry minority”—believe there was US government complicity in 9/11, and a recent poll (see July 6-24, 2006) found 16 percent of Americans believe the WTC towers were brought down with explosives. [National Institute of Standards and Technology, 8/31/2006; New York Times, 9/2/2006; Reuters, 9/2/2006] The fact sheet responds to 14 “Frequently Asked Questions.” Some of its key points include the following:
bullet Regarding whether NIST considered a controlled demolition hypothesis: “NIST found no corroborating evidence for alternative hypotheses suggesting that the WTC towers were brought down… using explosives… Instead, photographs and videos from several angles clearly show that the collapse initiated at the fire and impact floors and that the collapse progressed from the initiating floors downward until the dust clouds obscured the view.” However, it admits, “NIST did not test for the residue” of explosives in the remaining steel from the towers.
bullet Its explanation for puffs of smoke seen coming from each tower as it collapsed: “[T]he falling mass of the building compressed the air ahead of it—much like the action of a piston—forcing smoke and debris out the windows as the stories below failed sequentially.”
bullet Its explanation for a stream of yellow molten metal that poured down the side of the South Tower shortly before it collapsed (see (9:50 a.m.) September 11, 2001). NIST previously claimed it was aluminum, but this should not have been yellow in color: “Pure liquid aluminum would be expected to appear silvery. However, the molten metal was very likely mixed with large amounts of hot, partially burned, solid organic materials (e.g., furniture, carpets, partitions and computers) which can display an orange glow.”
bullet Regarding reports of molten steel in the wreckage at Ground Zero (see September 12, 2001-February 2002): “Any molten steel in the wreckage was more likely due to the high temperature resulting from long exposure to combustion within the pile than to short exposure to fires or explosions while the buildings were standing.”
bullet Regarding the collapse of WTC 7 (see (5:20 p.m.) September 11, 2001): “While NIST has found no evidence of a blast or controlled demolition event, NIST would like to determine the magnitude of hypothetical blast scenarios that could have led to the structural failure of one or more critical elements.” [National Institute of Standards and Technology, 8/30/2006] In response to the fact sheet, Kevin Ryan, the coeditor of the online Journal of 9/11 Studies, says, “The list of answers NIST has provided is generating more questions, and more skepticism, than ever before.” He says, “NIST is a group of government scientists whose leaders are Bush appointees, and therefore their report is not likely to veer from the political story.” [New York Times, 9/2/2006; Reuters, 9/2/2006]

Insurance companies reach a $2 billion settlement with real estate development and investment firm Silverstein Properties for the destruction of the World Trade Center on 9/11. The agreement, which involves seven of the two-dozen insurers for the WTC, ends more than five years of legal wrangling. The other insurance companies involved have already paid out about $2.55 billion, meaning the total payout will be $4.55 billion. In September 2006, Silverstein Properties and the New York Port Authority had agreed to split the reconstruction of the WTC site between them, and to divide up the remaining insurance proceeds accordingly. Consequently, the Port Authority is to receive about $870 million from the latest settlement, while the remaining $1.13 billion will go to Silverstein Properties. [New York State, 5/23/2007; New York Times, 5/23/2007; Newsday, 5/23/2007; Reuters, 5/23/2007] Silverstein Properties acquired the lease on several of the World Trade Center buildings, including the Twin Towers, in July 2001 (see July 24, 2001). [Port Authority of New York and New Jersey, 7/24/2001] As the New York Times summarizes, “At that time, two dozen insurers had signed binders pledging to provide $3.5 billion in insurance coverage, but had not finished the documentation.” Therefore, after 9/11, an “ugly dispute developed over which insurance policy was in effect at the time of the attack. Mr. [Larry] Silverstein [the president of Silverstein Properties] argued that since two jetliners slammed into the two towers, he was entitled to a double payment on the $3.5 billion policy. But many of the insurers countered that they had agreed to a different policy that did not permit double claims.” [New York Times, 5/23/2007] In 2004, federal juries had decided that Silverstein Properties could collect a maximum of $4.68 billion for the loss of the WTC. The current settlement therefore means the insurers are obliged to pay 97.2 percent of that maximum. [Bloomberg, 5/23/2007; New York State, 5/23/2007; Newsday, 5/23/2007; Reuters, 5/23/2007] Silverstein Properties had separately been awarded $861 million of insurance money in 2002 for the loss of World Trade Center Building 7, which also collapsed on 9/11 (see May 2002).

In a reply to criticisms of its World Trade Center investigation, the National Institute of Standards and Technology (NIST) admits that it is unable to fully explain the total collapse of the Twin Towers on 9/11. NIST’s letter is a response to a “request for correction” letter sent to it five months earlier by Bob McIlvaine and Bill Doyle, who both lost family members on 9/11, along with scientists Kevin Ryan and Steven E. Jones, architect Richard Gage, and the group Scholars for 9/11 Truth and Justice. This letter made several assertions about NIST’s final reports of its WTC investigation, and suggested they had violated the Data Quality Act and NIST’s information quality standards. NIST’s reply denies the requests for corrections. However, it also mentions, “[W]e are unable to provide a full explanation of the total collapse” of the World Trade Center. [National Institute of Standards and Technology, 9/27/2007 pdf file] In its final report on the Twin Towers collapses, released in October 2005, NIST admitted that its investigation did “not actually include the structural behavior of the tower after the conditions for collapse initiation were reached and collapse became inevitable” (see October 26, 2005).

The National Institute of Standards and Technology (NIST) publishes a fact sheet responding to 14 “frequently asked questions” about its investigation into the collapse of the Twin Towers on September 11. Some of the key questions and answers are as follows:
bullet Regarding the question, “Why was the collapse of WTC 1 and 2 not arrested by the intact structure below the floors where columns first began to buckle?” NIST replies, “The vertical capacity of the connections supporting an intact floor below the level of collapse was adequate to carry the load of 11 additional floors if the load was applied gradually and 6 additional floors if the load was applied suddenly (as was the case).” As the number of floors above the points where the collapses initiated exceeded six (12 in the case of the North Tower, 29 for the South), NIST says, “[T]he floors below the level of collapse initiation were unable to resist the suddenly applied gravitational load from the upper floors of the buildings.”
bullet In answer to the question of “Why was physical evidence not collected immediately following the collapse of the WTC towers,” NIST says, “In the initial days and weeks following the WTC disaster, the emphasis was on rescue and later on recovery, necessitating the removal of steel and disturbing the collapse site.” It adds, “NIST did not receive the legal authority to collect and preserve physical evidence from a disaster/failure site until the National Construction Safety Team Act became law in October 2002.” The decision to rapidly scrap the remaining steel from the WTC was made shortly after 9/11 (see Shortly After September 11, 2001), but the destruction of this steel was strongly protested by some within the engineering and firefighting communities (see December 25, 2001 and January 4, 2002).
bullet In response to a question about why it did not use its subpoena authority during its investigation, NIST states that its “experience during the investigation was that it was able to obtain all essential documentary and visual evidence without the need to invoke subpoena authority.”
bullet In answer to the question, “Why didn’t NIST fully model the collapse initiation and propagation of WTC towers?” NIST says, “Once the collapse had begun, the propagation of the collapse was readily explained without the same complexity of modeling” as was used to determine the sequence of events leading up to the collapse initiation.
bullet During its investigation, NIST had selected several variables for its computer simulations, and then experimented with different possible values (see (October 2002-October 2005)). But it has been asked: “Why didn’t NIST consider the ‘base’ and ‘less severe’ cases throughout its analysis of the WTC towers? What was the technical basis for selecting only the ‘more severe’ case for its analyses?” Its answer is that, “Of the three [possible values], the more severe case resulted in the closest agreement with the visual and physical evidence.” [National Institute of Standards and Technology, 12/14/2007]
NIST published its final report on the Twin Towers collapse in October 2005 (see October 26, 2005). It released an earlier fact sheet answering previous “frequently asked questions” in August 2006 (see August 30, 2006). [National Institute of Standards and Technology, 8/30/2006]

It is revealed that Larry Silverstein, the developer of Ground Zero, is seeking $12.3 billion in damages from airlines and airport security companies for the attacks on 9/11. Silverstein sought the damages in a claim filed in 2004, alleging that the companies failed to prevent the hijackers from taking over the planes that destroyed the World Trade Center buildings. The size of his claim was previously unknown, but is now revealed at a status conference in the US District Court in Manhattan. [New York Times, 3/27/2008] Of the $12.3 billion sought, $8.4 billion would be to replace the property destroyed in the attacks, and the other $3.9 billion would cover lost income and expenses associated with renting the new buildings. Companies named in the suit include American Airlines, United Airlines, Continental Airlines, Boeing, and the Massachusetts Port Authority (Massport), which manages Logan Airport in Boston, from where the two planes that hit the WTC took off. [CNN, 3/27/2008] Silverstein’s case is consolidated with similar, earlier lawsuits by other property owners and some families of 9/11 victims. Silverstein is by far the biggest of the claimants. A lawyer for the airlines says that if Silverstein wins, it could push the total claims beyond the amount of insurance the airlines and security companies have available. Silverstein, the CEO and president of Silverstein Properties, only signed the 99-year lease on the World Trade Center six weeks before 9/11 (see July 24, 2001). He has already won nearly $4.6 billion in insurance payments stemming from the attacks (see May 23, 2007). [New York Times, 3/27/2008; NY1 News, 3/28/2008]

Explosives on a chipExplosives on a chip [Source: Gary Meek/Georgia Institute of Technology]According to an article published in The Environmentalist, a peer-reviewed scientific journal published by Springer Netherlands, air quality data collected by the Environmental Protection Agency (EPA) at Ground Zero support the hypothesis that cutting charges made with thermite were used to demolish the World Trade Center. The article by authors (and 9/11 truth activists) Kevin Ryan, James Gourley, and Steven Jones says the presence of thermite would best explain three major documented anomalies: [Ryan, Gourley, and Jones, 8/4/2008]
1) The Persistence of Fires at Ground Zero - As has been extensively reported, the rubble at Ground Zero continued to burn for months after 9/11, despite rain as well as firefighters’ use of large quantities of water and of the chemical fire suppressant Pyrocool. [New York Times, 11/19/2001] There is also eyewitness and photographic evidence of molten metal (see September 12, 2001-February 2002) and of explosions accompanied by white dust clouds. The book Aftermath: World Trade Center Archive by photographer Joel Meyerowitz shows a picture of such an explosion taking place on November 8, 2001. [Meyerowitz, 2006, pp. 178] Another photography books by NYPD officer John Botte also shows a picture of smoke emerging from the pile at Ground Zero and explains: “Occasionally, a huge flame would shoot out from the middle of the pile, sounding like a blow torch, as it did here.” [Botte, 2006, pp. 48-49]
2) Spikes of Certain Chemicals in the Air - EPA data shows that several spikes of chemical products of combustion, called volatile organic chemicals (VOC), occurred in October and November 2001, and in February 2002. According to the authors, these spikes indicate “abrupt, violent fires.”
3) The Presence of 1,3-Diphenylpropane - A third anomaly was the presence of large quantities of 1,3-diphenylpropane (1,3-DPP) in the air, a chemical that had not been found in previous structure fires. An EPA scientist told Newsday, “We’ve never observed it in any sampling we’ve ever done.” [Newsday, 9/14/2003]
A possible explanation would be the presence of novel “energetic nanocomposites” which include 1,3-DPP, according to scientific articles reviewed by Ryan et al. Such materials are “amenable to spray-on applications.” A 2002 report said: “The energetic coating dries to give a nice adherent film. Preliminary experiments indicate that films of the hybrid material are self-propagating when ignited by thermal stimulus.” [Ryan, Gourley, and Jones, 8/4/2008] The main center for nanocomposites research is Lawrence Livermore National Laboratory (LLNL). An October 2000 article in a LLNL publication provided an introduction to the research conducted there: “Energetic nanocomposites have a fuel component and an oxidizer component mixed together. […] In one such material (termed a thermite pyrotechnic), iron oxide gel reacts with metallic aluminum particles to release an enormous amount of heat. ‘These reactions typically produce temperatures in excess of 3,500 degrees Celsius’ says [LLNL researcher Randy] Simpson.” [Science & Technology Review, 10/2000] The authors conclude that “[t]he presence of energetic materials, specifically energetic nanocomposites, at [Ground Zero], has the potential to explain much of the unusual environmental data seen at the WTC. Thermite […] is such a pyrotechnic mixture that cannot be easily extinguished and is a common component of energetic nanocomposites.… [T]he detection of 1,3-DPP at the WTC supports this hypothesis. Finally, the spikes in VOCs, detected by EPA on specific dates, are more readily explained as a result of short-lived, violent fires caused by energetic materials.” [Ryan, Gourley, and Jones, 8/4/2008]

[Source: Don Berkemeyer / National Institute of Standards and Technology]The National Institute of Standards and Technology (NIST) announces the findings of its study of the collapse of World Trade Center Building 7, and says the 47-story tower fell late in the afternoon of 9/11 primarily due to fires. [National Institute of Standards and Technology, 8/21/2008; National Institute of Standards and Technology, 8/21/2008] NIST releases its findings as part of a 915-page report, which is the result of three years’ work by over 50 federal investigators and a dozen contractors (see August 21, 2008). [New York Times, 8/21/2008]
Collapse Is 'No Longer a Mystery' - In a news conference at NIST’s headquarters in Gaithersburg, Maryland, lead investigator Shyam Sunder admits: “[W]e knew from the beginning of our study that understanding what happened to Building 7 on 9/11 would be difficult. It did not fit any textbook description that you could readily point to and say, yes, that’s why the building failed.” But, he says, “[T]he reason for the collapse of World Trade Center 7 is no longer a mystery.” [National Institute of Standards and Technology, 8/21/2008; New York Times, 8/21/2008]
'New Phenomenon' Caused Collapse - Sunder says the “critical factor” that initiated the collapse was “thermal expansion of long-span floor systems located in the east side of the building,” and adds that NIST’s study “has identified thermal expansion as a new phenomenon that can cause structural collapse. For the first time we have shown that fire can induce a progressive collapse.”
Collapse Sequence - Sunder describes the sequence of events NIST believes led to the collapse of WTC 7. He says debris from the collapse of the north WTC tower “started fires on at least 10 floors of the building. The fires burned out of control on six of these 10 floors for about seven hours. The city water main had been cut by the collapse of the two WTC towers, so the sprinklers in Building 7 did not function for much of the bottom half of the building.” He continues: “Fires on floors 7 through 9 and 11 through 13 were particularly severe.… Eventually, a girder on floor 13 lost its connection to a critical interior column.” Floor 13 collapsed, beginning a cascade of floor failures down to the fifth floor. “With the support of these floors gone, column 79 buckled, which initiated the fire-induced progressive collapse of the building.… This in turn caused the failure of nearby columns 80 and 81 and floor failures up to the roof line.… As the roof line begins to fall adjacent columns buckle as well. In quick succession, the remaining interior columns failed from east to west across WTC 7, until the entire core began moving downward. Finally, the remaining outer shell or façade of the building fell.”
NIST Created 'Virtual WTC 7' Model - Sunder says that NIST reached its conclusions about the collapse “by reconstructing the entire building, beam by beam, column by column, connection by connection into a computer model, a virtual WTC 7 building. We then filled that virtual building with as much detail as possible about exactly what types of furnishings were on each floor. Then we set fire to those virtual offices on the floors where video and other visual evidence told us the fires burned.” The investigators “used a well-validated computer program developed at NIST, for studying the growth and spread of fires, to calculate temperatures throughout the building.… And we used well-established data on the properties of structural steel, the sprayed fire resistive material or fireproofing, and other building materials to determine how those temperatures affected the structure.”
Explosives Not Used - Sunder says that the investigators “did not find any evidence that explosives were used to bring the building down” (see August 21, 2008), nor was the collapse “due to fires from the substantial amount of diesel fuel stored in the building” (see August 21, 2008). NIST commenced its investigation of the WTC collapses in 2002 (see August 21, 2002) and issued its findings on the collapses of the Twin Towers in October 2005 (see October 26, 2005). Since then it has been focused on WTC 7. [Government Computer News, 8/21/2008; National Institute of Standards and Technology, 8/21/2008]
Final Report to Be Released - After suggestions are made by members of the public in response to its current report, NIST will release a finished version of the same report in November 2008, thereby completing its WTC investigation (see November 20, 2008).

This is the completed version of the report, and comes three months after a draft version was released for public comment (see August 21, 2008). NIST states that the new report “is strengthened by clarifications and supplemental text suggested by organizations and individuals worldwide in response to the draft WTC 7 report.” NIST conducted an additional computer analysis in response to comments from the building community, and made several minor amendments to the report. But, it says, “the revisions did not alter the investigation team’s major findings and recommendations, which include identification of fire as the primary cause for the building’s failure.” With the release of this report, NIST has completed its six-year investigation of the World Trade Center collapses, which it commenced in August 2002 (see August 21, 2002). The final report of its investigation of the Twin Towers’ collapses was published in October 2005 (see October 26, 2005).
