[Source: Committee for a Reasonable World Trade Center]A civic group opposed to the building of the World Trade Center publishes a nearly full-page advertisement in the New York Times, warning that the new buildings will be so tall that a commercial airliner might crash into them. The group, called the Committee for a Reasonable World Trade Center, is mainly composed of New York real estate developers who are worried that the huge construction project will glut the market. Its leader is Lawrence A. Wien, a real estate mogul who is an owner of the Empire State Building in New York.

Hamilton and Cheney hold a press conference together about the Iran-Contra Affair investigation on June 19, 1987.Hamilton and Cheney hold a press conference together about the Iran-Contra Affair investigation on June 19, 1987. [Source: J. Scott Applewhite]Future 9/11 Commission vice chairman Lee Hamilton (D-IN), at this time chairman of the House Intelligence Committee, fails to properly investigate Iran-Contra allegations. He learns of press reports indicating that the Reagan administration is illegally funneling weapons and money to the anti-Communist rebels in Nicaragua, but when the White House denies the story, Hamilton believes it. Hamilton will later acknowledge that he has been gullible, and will say of his political style, “I don’t go for the jugular.” It is during the Iran-Contra investigation that Hamilton becomes friends with Dick Cheney, at this time a Republican congressman. [Shenon, 2008, pp. 33] Cheney is the ranking Republican on the House Intelligence Committee and so must work closely with Hamilton, including on the Iran-Contra investigation. [PBS, 6/20/2006] Hamilton calls Cheney “Dick” and they will remain friends even after Cheney becomes vice president in 2001 and Hamilton, as vice chairman of the 9/11 Commission, begins to investigate Cheney’s actions as a part of the Commission’s work. [Shenon, 2008, pp. 33] Hamilton will also fail to properly investigate “October Surprise” allegations (see 1992-January 1993).

In 1992, a House of Representatives task force chaired by Lee Hamilton (D-NH) conducts a ten-month investigation into the “October Surprise”—an alleged Republican plot to delay the release of US hostages held in Iran in 1980 until after that year’s US presidential election. The investigation concludes in 1993 that there is “no credible evidence” of any such plot. But Robert Parry, a journalist writing for the Associated Press and Newsweek, gains access to the stored records of Hamilton’s task force. He finds clear evidence of a major cover up. For instance, William Casey, CIA Director in the early 1980s, was alleged to have been involved in the plot, and Hamilton’s investigators discovered a CIA created index of Casey’s papers made after Casey’s death in 1987. When investigators searched Casey’s possessions, they found all the papers mentioned in the index, except for all the ones relevant to the alleged October Surprise plot. But the disappearance of such evidence was not mentioned in Hamilton’s findings. [Scott, 2007, pp. 101] In addition, an official Russian intelligence report placing Casey in Europe in order to arrange a politically favorable outcome to the hostage crisis arrived in Washington shortly before Hamilton’s task force issued their conclusions, but this Russian information was not mentioned by the task force. [Scott, 2007, pp. 106-107] Hamilton will later be appointed co-chair of the 9/11 Commission (see December 11, 2002).

In the wake of the WTC bombing, the Seattle Times interviews John Skilling who was one of the two structural engineers responsible for designing the Trade Center. Skilling recounts his people having carried out an analysis which found the Twin Towers could withstand the impact of a Boeing 707. He says, “Our analysis indicated the biggest problem would be the fact that all the fuel (from the airplane) would dump into the building. There would be a horrendous fire. A lot of people would be killed.” But, he says, “The building structure would still be there.” [Seattle Times, 2/27/1993] The analysis Skilling is referring to is likely one done in early 1964, during the design phase of the towers. A three-page white paper, dated February 3, 1964, described its findings: “The buildings have been investigated and found to be safe in an assumed collision with a large jet airliner (Boeing 707—DC 8) traveling at 600 miles per hour. Analysis indicates that such collision would result in only local damage which could not cause collapse or substantial damage to the building and would not endanger the lives and safety of occupants not in the immediate area of impact.” However, besides this paper, no documents are known detailing how this analysis was made. [Glanz and Lipton, 2004, pp. 131-132; Lew, Bukowski, and Carino, 10/2005, pp. 70-71] The other structural engineer who designed the towers, Leslie Robertson, carried out a second study later in 1964, of how the towers would handle the impact of a 707 (see Between September 3, 2001 and September 7, 2001). However, the National Institute of Standards and Technology (NIST), following its three-year investigation into the WTC collapses, will in 2005 state that it has been “unable to locate any evidence to indicate consideration of the extent of impact-induced structural damage or the size of a fire that could be created by thousands of gallons of jet fuel.” [National Institute of Standards and Technology, 9/2005, pp. 13]

On March 10, Nidal Ayyad is arrested for a role in the February 1993 World Trade Center bombing (see February 26, 1993). Investigators soon discover a letter threatening future attacks in a computer file that was deleted but recovered. It makes reference to an earlier letter sent by Ayyad to the New York Times taking credit for the bombing (see March 2, 1993), and says: “We are the Liberation Army Fifth Battalion again. Unfortunately, our calculations were not very accurate this time. However, we promise you that next time it will be very precise and WTC will continue to be one our targets in the US unless our demands are met.” The letter is signed by the same long Arabic alias used in Ayyad’s previous letter.

[Source: Harvard University Press]Future National Security Adviser and Secretary of State Condoleezza Rice and Philip Zelikow, who, as executive director of the 9/11 Commission, will investigate her performance in the run-up to 9/11, co-author a book about the implications of German reunification. The two had worked together on the National Security Council in the 1980s and early 90s, but are both now working at universities. Zelikow is a professor at the Kennedy School of Government at Harvard University, and Rice is the provost at Stanford. The book, entitled Germany Unified and Europe Transformed: A Study in Statecraft, is mostly written by Zelikow, who is, in author Philip Shenon’s words, “pleased to share credit with such an obvious up-and-comer as Rice.” [Shenon, 2008, pp. 40-41]

Marvin Bush.Marvin Bush. [Source: Eric Draper / White House]A security company called Stratesec acquires an $8.3 million contract to help provide security at the World Trade Center. It is one of numerous contractors hired in the upgrade of security at the WTC following the 1993 bombing. Stratesec, which was formerly called Securacom, is responsible for installing the “security-description plan”—the layout of the electronic security system—at the World Trade Center. It has a “completion contract” to provide some of the center’s security “up to the day the buildings fell down,” according to Barry McDaniel, its CEO.
Involved with Airport Security - Another of Stratesec’s biggest security contracts, between 1995 and 1998, is with the Metropolitan Washington Airport Authority, providing electronic security for Reagan National Airport and Dulles International Airport. Its work includes maintaining the airfield access systems, the CCTV (closed circuit television) systems, and the electronic badging systems. American Airlines Flight 77—one of the planes hijacked on 9/11—takes off from Dulles.
Directors Include Bush Family Member - Marvin P. Bush, the youngest brother of future President George W. Bush, is a director at Stratesec from 1993 to June 2000, when most of its work on these big projects is done. Wirt D. Walker III, a distant relative of George W. Bush, is chairman of the board at Stratesec from 1992, and its CEO from 1999 until January 2002. Another of Stratesec’s directors, from 1991 to 2001, is Mishal Yousef Saud Al Sabah, who is a member of the Kuwaiti royal family. Al Sabah is also chairman of an investment company called the Kuwait-American Corporation (KuwAm), which, between 1993 and 1999, holds a large, often controlling share of Stratesec. In 1996, it owns 90 percent of the company; by 1999 it owns 47 percent.
Other Interests - Walker and Al Sabah are also co-investors in two inter-related aviation companies: Aviation General and Commander Aircraft. According to a 2005 report by freelance journalist Margie Burns: “Aviation General boasted of its international clientele. A 1996 press release announced its sale of airplanes to the National Civil Aviation Training Organization (NCATO) of Giza, Egypt, ‘the sole civilian pilot training organization in Egypt.’ The announcement mentions Al Sabah as chairman of KuwAm and board member of Commander Aircraft Company.” NCATO also has contractual partnerships with several US flight schools, including Embry-Riddle University in Florida.
Connections with Foreign Company a Delicate Matter - According to Wayne Black, the head of a Florida-based security firm, it is delicate for a security company serving international facilities to be so interlinked with a foreign-owned company. He suggests, “Somebody knew somebody.” Black also points out that when a company has a security contract, “you know the inner workings of everything.” Furthermore, if another company is linked to the security company, then “what’s on your computer is on their computer.” After 9/11 Stratesec CEO Barry McDaniel will be asked whether FBI or other agents have questioned him or others at Stratesec about their security work related to 9/11. He answers, “No.” [American Reporter, 1/20/2003; Prince George's Journal, 2/4/2003; Progressive Populist, 3/1/2003; Progressive Populist, 4/15/2003; Washington Spectator, 2/15/2005] Other companies involved with the security overhaul during this time include Ensec Inc., which is in charge of creating a new parking access control system, E-J Electric Installation Co., and Electronic Systems Associates, a division of Syska Hennessy.

Ashton Carter.Ashton Carter. [Source: Aspen Institute]Over a period of nine months, faculty from Harvard University, Stanford University, the Massachusetts Institute of Technology, and the University of Virginia meet in a collaborative effort called the Catastrophic Terrorism Study Group. Its members include experts on terrorism, national security, intelligence, and law enforcement. The project director is Philip Zelikow, future executive director of the 9/11 Commission. Future 9/11 Commissioner Jamie Gorelick is also a member, along with Ernest May, who will be a senior advisor to the 9/11 Commission. The culmination of the group’s efforts is a report written by Zelikow and its two co-chairs: former Assistant Secretary of Defense Ashton Carter and former CIA Director John Deutch. A condensed version of the report is published in the journal Foreign Affairs in late 1998. They write: “Long part of the Hollywood and Tom Clancy repertory of nightmarish scenarios, catastrophic terrorism has moved from far-fetched horror to a contingency that could happen next month. Although the United States still takes conventional terrorism seriously… it is not yet prepared for the new threat of catastrophic terrorism.” They predict the consequences of such an event: “An act of catastrophic terrorism that killed thousands or tens of thousands of people and/or disrupted the necessities of life for hundreds of thousands, or even millions, would be a watershed event in America’s history. It could involve loss of life and property unprecedented for peacetime and undermine Americans’ fundamental sense of security within their own borders in a manner akin to the 1949 Soviet atomic bomb test, or perhaps even worse. Constitutional liberties would be challenged as the United States sought to protect itself from further attacks by pressing against allowable limits in surveillance of citizens, detention of suspects, and the use of deadly force. More violence would follow, either as other terrorists seek to imitate this great ‘success’ or as the United States strikes out at those considered responsible. Like Pearl Harbor, such an event would divide our past and future into a ‘before’ and ‘after.’” [Carter, Deutch, and Zelikow, 10/1998; Foreign Affairs, 11/1998; 9/11 Commission, 7/24/2004, pp. xi-xiv]

It is later revealed that, in the years up to 9/11, New York City Mayor Rudolph Giuliani has little knowledge of the threat posed by al-Qaeda. [MSNBC, 10/25/2007] In private testimony before the 9/11 Commission in 2004, after being asked about the “flow of information about al-Qaeda threats from 1998-2001,” Giuliani will reply, “At the time, I wasn’t told it was al-Qaeda, but now that I look back at it, I think it was al-Qaeda.” Giuliani will also concede that it was only “after 9/11” that “we brought in people to brief us on al-Qaeda.” Before 9/11, he says, “we had nothing like this… which was a mistake, because if experts share a lot of info,” there would be a “better chance of someone making heads and tails” of the situation. [Village Voice, 10/23/2007] In a later television interview, he will admit that he “didn’t see the enormity of” the threat al-Qaeda posed to the United States prior to 9/11, and add: “I never envisioned the kind of attack that they did.… [W]hat I envisioned were the kind of suicide bombings that had gone on in, in Israel. I had been briefed on that.… But I had no idea of the kind of level of attack that was in store for us.” [MSNBC, 12/9/2007] He blames his lack of knowledge on terrorism partly on the FBI and the Joint Terrorism Task Force (JTTF), a partnership between the FBI and the New York City Police Department. Giuliani will state: “We already had JTTF, and got flow information no one else got. But did we get the flow of information we wanted? No. We would be told about a threat, but not about the underlying nature of the threat. I wanted all the same information the FBI had, and we didn’t get that until after 9/11.” [Village Voice, 10/23/2007] He will also complain, “I was dependent on the briefings that I was getting from… the [Clinton] administration, and… I don’t think they saw the threat as big as it was.” [MSNBC, 12/9/2007] In 2004, the 9/11 Commission asks Thomas Von Essen, who is Giuliani’s fire commissioner, what information he had about terrorism prior to 9/11. He will reply, “I was told nothing at all.” Yet in a speech in 2007, Giuliani will claim that, with the 1993 World Trade Center bombing: “Bin Laden declared war on us.… I thought it was pretty clear at the time, but a lot of people didn’t see it, couldn’t see it.” He also claims to have been “studying terrorism” for more than 30 years.

In his opening remarks at a conference on contemporary political history organized by the Miller Center of Public Affairs at the University of Virginia, future 9/11 Commission Executive Director Philip Zelikow emphasizes that the public understanding of history is shaped by what are sometimes referred to as “public myths.” “[U]nderstanding contemporary political history is extremely important and constantly alive in public discourse. ‘Contemporary’ is defined functionally by those critical people and events that go into forming the public’s presumptions about its immediate past. This idea of ‘public presumption’ is akin to William McNeill’s notion of ‘public myth’ but without the negative implication sometimes invoked by the word ‘myth.’ Such presumptions are beliefs (1) thought to be true (although not necessarily known to be true with certainty), and (2) shared in common within the relevant political community. The sources for such presumptions are both personal (from direct experience) and vicarious (from books, movies, and myths).” Zelikow says that public assumptions often grow out of “searing events”: “particularly ‘searing’ or ‘molding’ events take on ‘transcendent’ importance and, therefore, retain their power even as the experiencing generation passes from the scene.” [Zelikow, 1999 pdf file] In a previous publication, Zelikow had written about how a “catastrophic terrorism” event could constitute a momentous, history-shaping milestone: “An act of catastrophic terrorism that killed thousands or tens of thousands of people… would be a watershed event in America’s history.… Like Pearl Harbor, such an event would divide our past and future into a ‘before’ and ‘after’” (see November 1997-August 1998).

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.

The North Tower of the WTC suffers a fire on its 104th floor. This is the 15th and last of what the National Institute of Standards and Technology later describes as “significant fires,” which occurred in the Twin Towers from 1975 onwards, and prior to 9/11. These fires each activate up to three sprinklers but are confined to just one floor. [Kuligowski, Evans, and Peacock, 9/2005, pp. 7-11] Additionally, on February 14, 1975 a major fire occurred, the result of arson, which began on the 11th floor of the North Tower during the middle of the night. Spreading through floor openings in the utility closets, it caused damage from the 10th to 19th floors, though this was generally confined to the utility closets. However, on the 11th floor about 9,000 square feet was damaged. This was about 21 percent of the floor’s total area (43,200 square feet) and took weeks to repair. Some parts of the steel trusses (floor supports) buckled due to the heat. 132 firefighters were called to the tower in response, and because the fire was so hot, many got their necks and ears burned. Fire Department Captain Harold Kull described the three-hour effort to extinguish it as “like fighting a blowtorch.” [WTC Environmental Assessment Working Group, 9/2002, pp. 10 pdf file; New York Times, 5/8/2003; Glanz and Lipton, 2004, pp. 213, 214, 324; Kuligowski, Evans, and Peacock, 9/2005, pp. 1] An article in Fire Engineering magazine will later summarize, “[A]lmost all large buildings will be the location for a major fire in their useful life. No major high-rise building has ever collapsed from fire. The WTC was the location for such a fire in 1975; however, the building survived with minor damage and was repaired and returned to service.” [Fire Engineering, 10/2002] Building 7 of the WTC, which completely collapses late in the afternoon on 9/11, has also suffered a ‘significant’ fire in 1988, occurring on its third floor, with multiple sprinklers being activated.

Historian Ernest May.Historian Ernest May. [Source: Belfer Center]An eminent historian finds serious flaws in a historical treatise about former President John F. Kennedy. The book, The Kennedy Tapes: Inside the White House During the Cuban Missile Crisis, was written in 1997 by conservative historians Ernest May and Philip D. Zelikow, and purports to be an unprecedentedly accurate representation of the events of 1962’s Cuban Missile Crisis based on transcriptions of recorded meetings, conferences, telephone conversations, and interviews with various participants. [Atlantic Monthly, 5/2000] Zelikow is a former member of George H. W. Bush’s National Security Council and a close adviser to future National Security Adviser Condoleezza Rice. [US Department of State, 8/5/2005] May is a Harvard professor. Both will participate heavily in the creation of the 2004 report by the 9/11 Commission. [Shenon, 2008, pp. 387-393] Almost three years after the Kennedy book’s publication, Sheldon M. Stern, the historian for the John F. Kennedy Library from 1977 through 1999, pores over it and the May/Zelikow transcripts. In the original edition, May and Zelikow admitted that their final product was not perfect: “The reader has here the best text we can produce, but it is certainly not perfect. We hope that some, perhaps many, will go to the original tapes. If they find an error or make out something we could not, we will enter the corrections in subsequent editions or printings of this volume.” But when Stern checks the book against the tapes, he finds hundreds of errors in the book, some quite significant. Stern concludes that the errors “significantly undermine [the book’s] reliability for historians, teachers, and general readers.” May and Zelikow have corrected a few of the errors in subsequent editions, but have not publicly acknowledged any errors. Stern concludes, “Readers deserve to know that even now The Kennedy Tapes cannot be relied on as an accurate historical document.” [Atlantic Monthly, 5/2000] One error has then-Attorney General Robert F. Kennedy talking about the planned “invasion” of Russian ships heading to Cuba, when the tapes actually show Kennedy discussing a far less confrontational “examination” of those vessels. May and Zelikow imply that the Kennedy administration was discussing just the kind of confrontation that it was actually trying to avoid. Another error has CIA Director John McCone referring to the need to call on former President Dwight D. Eisenhower as a “facilitator,” where McCone actually said “soldier.” May and Zelikow will be rather dismissive of Stern’s findings, saying that “none of these amendments are very important.” Stern will express shock over their response, and respond, “When the words are wrong, as they are repeatedly, the historical record is wrong.” [Shenon, 2008, pp. 42]

Future 9/11 Commission Executive Director Philip Zelikow is not offered a job in the Bush administration, and returns to the Miller Center of Public Affairs at the University of Virginia to teach. Zelikow had worked on the transition team (see January 3, 2001), and thought he would receive an important position in the new administration. He told his friends he thought he was in line for the position of deputy national security adviser to Condoleezza Rice, with whom he had written a book in the mid-1990s (see 1995). Most people in the Bush administration admire his ability, but find him hard to work with. White House Chief of Staff Andrew Card will even describe Zelikow as a “bully” historian. Author Philip Shenon will later comment that Zelikow is “perplexed that his talents had not been recognized by the people who handed out the best jobs in the Bush administration.” After returning to university, Zelikow will lobby the White House to make the university where he works the official repository of its oral history. His point of contact at the White House is political adviser Karl Rove. [Shenon, 2008, pp. 42-44]

However, she downgrades his official position as National Coordinator for Counterterrorism. While he is still known as the counterterrorism “tsar,” he has less power and now reports to deputy secretaries instead of attending Cabinet-level meetings. He no longer is able to send memos directly to the president, or easily interact with Cabinet-level officials.

'I Don't Want to Hear about It Anymore' - According to a June 24, 2004 letter from Pickard to the 9/11 Commission, Pickard opens the briefing by discussing “counterintelligence and counterterrorism matters.” Pickard’s letter will go on to say: “The fourth item I discussed was the continuing high level of ‘chatter’ by al-Qaeda members. The AG [attorney general] told me, ‘I don’t want to hear about it anymore, there’s nothing I can do about it.’ For a few seconds, I did not know what to say, then I replied that he should meet with the director of the CIA to get a fuller briefing on the matter.… I resumed my agenda but I was upset about [Ashcroft’s] lack of interest. He did not tell me nor did I learn until April 2004 that the CIA briefed him on the increase in chatter and level of threat on July 5, 2001” (see July 5, 2001 and July 11-17, 2001). [Pickard, 6/24/2004] In testimony under oath to the 9/11 Commission in 2004, Pickard will affirm that, “at least on two occasions” he briefed Ashcroft on a rising threat level and concerns about an impending attack, which were being reported by the CIA. Commissioner Richard Ben-Veniste will ask Pickard if he has told Commission staff that Ashcroft “did not want to hear about this anymore,” to which Pickard will respond, “That is correct.” [9/11 Commission, 4/13/2004 pdf file] According to Pickard’s later recollection: “Before September 11th, I couldn’t get half an hour on terrorism with Ashcroft. He was only interested in three things: guns, drugs, and civil rights.” [Miller, Stone, and Mitchell, 2002, pp. 293]
Differing Accounts of What Was Said at the Meeting - According to the 9/11 Commission’s June 3, 2004 record of its interview with Watson, “Pickard told Watson that he was briefing Ashcroft on counterterrorism, and Ashcroft told him that he didn’t want to hear ‘anything about these threats,’ and that ‘nothing ever happened.’” [9/11 Commission, 6/3/2004 pdf file] Author Philip Shenon will write about this meeting in his 2008 book, The Commission, based on interviews with Pickard and “Commission investigators who researched his allegations,” but none of the quotes or representations of fact in Shenon’s text will cite a specific source. Shenon will make reference to Mark Jacobson and Caroline Barnes as being the 9/11 Commission staffers who interviewed Pickard. [Shenon, 2008, pp. 240-248, 433] According to Shenon’s version of the meeting, Ashcroft replies to Pickard: “I don’t want you to ever talk to me about al-Qaeda, about these threats. I don’t want to hear about al-Qaeda anymore.” [Shenon, 2008, pp. 247] Ashcroft, in testimony under oath to the 9/11 Commission, will dismiss Pickard’s allegation, saying, “I did never speak to him saying that I did not want to hear about terrorism.” [9/11 Commission, 4/13/2004 pdf file] Pickard will respond to Ashcroft’s testimony in his 2004 letter, saying, “What [Ashcroft] stated to the Commission under oath is correct, but they did not ask him, ‘Did he tell me he did not want to hear about the chatter and level of threat?’ which is the conversation to which I testified under oath.” [Pickard, 6/24/2004] The deputy attorney general at the time of the meeting, Larry D. Thompson, and Ashcroft’s chief of staff, David T. Ayres, will sign a letter to the 9/11 Commission on July 12, 2004, in which they say they are responding to Pickard’s allegation that when he briefed Ashcroft “on the al-Qaeda threat prior to September 11, 2001, the attorney general responded that he did not want to hear such information anymore.” The letter will say Thompson and Ayres were present at that and the other regular meetings between Pickard and Ashcroft, and “the attorney general made no such statement in that or any other meeting.” [Ayres, 7/12/2004] The 9/11 Commission Report will conclude, “We cannot resolve this dispute.” [Commission, 2004]
Differing Accounts of Who Was at the Meeting - Pickard’s 2004 letter will state that Ayres is at the meeting, but has left the room prior to that part of the meeting, as he does not have the required level of security clearance. Pickard’s letter indicated that the FBI Assistant Director for Criminal Investigations, Ruben Garcia, is at the meeting and also witnesses the exchange. [Pickard, 6/24/2004] Shenon’s book puts Garcia at the meeting, but does not make reference to Garcia’s account of what is said there. Also, in the notes to Shenon’s book, it will not say that he interviewed Garcia. [Shenon, 2008, pp. 247-248, 433] According to a June 22, 2004 NBC News report: “Commission investigators also tracked down another FBI witness at the meeting that day, Ruben Garcia… Several sources familiar with the investigation say Garcia confirmed to the Commission that Ashcroft did indeed dismiss Pickard’s warnings about al-Qaeda.” Furthermore, “Pickard did brief Ashcroft on terrorism four more times that summer, but sources say the acting FBI director never mentioned the word al-Qaeda again in Ashcroft’s presence—until after Sept. 11.” [MSNBC, 6/22/2004] According to the 9/11 Commission Report, “Ruben Garcia… attended some of Pickard’s briefings of the attorney general but not the one at which Pickard alleges Ashcroft made the statement.” [Commission, 2004, pp. 536n52]
Ashcroft Denies FBI Requests and Appeals, Cuts Counterterrorism Funding - Following the meeting, on July 18, Ashcroft will reject the FBI’s request for an increase in funding for counterterrorism, and instead propose cuts to that division (see July 18, 2001). Pickard will appeal this decision; Ashcroft will reject the appeal on September 10, 2001 (see September 10, 2001). [9/11 Commission, 4/13/2004]

A property risk assessment report is prepared for Silverstein Properties before it acquires the lease for the World Trade Center (see July 24, 2001). It identifies the scenario of an aircraft hitting one of the WTC towers as one of the “maximum foreseeable losses.” The report says, “This scenario is within the realm of the possible, but highly unlikely.” Further details of the assessment, such as who prepared it, are unreported.

Larry Silverstein. [Source: Silverstein Properties publicity photo]Real estate development and investment firm Silverstein Properties and real estate investment trust Westfield America Inc. finalize a deal worth $3.2 billion to purchase a 99-year lease on the World Trade Center. The agreement covers the Twin Towers, World Trade Center Buildings 4 and 5 (two nine-story office buildings), and about 425,000 square feet of retail space. [New York Times, 4/27/2001; Port Authority of New York and New Jersey, 7/24/2001; IREIzine, 7/26/2001] Westfield America Inc. will be responsible for the retail space, known as the Mall. 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. [International Council of Shopping Centers, 4/27/2001; Westfield Group, 7/24/2001; Daily Telegraph, 9/11/2001; New York Times, 11/29/2001; CNN, 8/31/2002] It was previously controlled by the New York Port Authority, a bi-state government agency. [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. Eisenberg, the chairman of the Port Authority. Eisenberg, a financier, is involved in Republican politics. [New York Times, 3/17/2001; Forward, 8/20/2004]
Banks Provide Most Money for Deal - Larry Silverstein, the president of Silverstein Properties, only uses $14 million of his own money for the deal. His partners, who include real estate investors Lloyd Goldman and Joseph Cayre, put up a further $111 million, and banks provide $563 million in loans. [Brill, 2003, pp. 156; New York Times, 11/22/2003; South Florida CEO, 2/2005; Wall Street Journal, 9/11/2008]
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]

A Federal Express 727 lands in New Mexico in August 2001.A Federal Express 727 lands in New Mexico in August 2001. [Source: Associated Press]US company Raytheon flies and lands a Federal Express 727 passenger jet six times on a military base in New Mexico, entirely by remote control and without a pilot on board. This is done to test equipment intended to make hijackings difficult, by allowing ground controllers to take over the flying of a hijacked plane. The Associated Press will later report, “[T]he Raytheon test used technology that provides the extremely precise navigational instructions that would be required for remote control from a secure location.” The Associated Press will observe, “Unmanned, ground controlled reconnaissance aircraft have been used by the military for missions over Iraq and Kosovo,” and will quote Thomas Cassidy, president of the California-based General Atomics Aeronautical Systems and manufacturer of the military aircraft, as saying, “It’s a reliable system.” [Associated Press, 10/2/2001; Der Spiegel (Hamburg), 10/28/2001]
Raytheon Employees on 9/11 Planes - Several Raytheon employees with possible ties to this remote control technology and/or Raytheon’s Global Hawk program will be reported to have been on the hijacked 9/11 flights (see September 25, 2001). Earlier in the year, a specially designed Global Hawk plane flew from the US to Australia without pilots or passengers. [ITN, 4/24/2001]
Others Say Remote Control Is Impossible - Contradicting the Associated Press report, a number of media reports after 9/11 will suggest such technology is impossible, or flatly deny its existence. For instance, The Observer will quote an expert as saying, “the technology is pretty much there,” but is still untried. [Observer, 9/16/2001] An aviation-security expert at Jane’s Defence Weekly will say this type of technology belongs “in the realms of science fiction.” [Financial Times, 9/18/2001; Economist, 9/20/2001] And in late September 2001, President Bush will give a speech in which he mentions that the government would give grants to research “new technology, probably far in the future, allowing air traffic controllers to land distressed planes by remote control.” [New York Times, 9/28/2001]

Future 9/11 hijacker Fayez Ahmed Banihammad attempts to get into an airplane cockpit on a test flight across the US, according to flight attendant Gregory McAleer. McAleer is employed by United Airlines. He will later claim to the 9/11 Commission that on August 30, 2001, he is working on Flight 514, a Boeing 737-300 flying from Chicago’s O’Hare Airport to Logan Airport in Boston.
Strange Encounter - Early in the boarding process a Middle Eastern male enters the airplane with a “jump seat” pass. This pass allows the person to sit in the jump seat, an extra seat in the airplane’s cockpit. Typically, only licensed pilots employed by US domestic airlines are given these passes. The man is not dressed in a pilot’s uniform, but wears casual clothes and carries a suitcase. McAleer sees this man entering the cockpit and talking to the pilot and copilot. After a few moments, the man leaves the cockpit and takes a seat in the coach section. McAleer is curious and asks the pilot about the man. The pilot says the man can’t use the jump seat since he doesn’t have the proper ID. Later in the flight, McAleer has a chance to question the man while both of them are waiting to use the lavatory. The man claims to be a pilot for a regional airline, but when McAleer, who has a pilot’s license, asks him questions about his job and his knowledge of flying, the answers don’t add up and the man also asks him some suspicious questions. McAleer finds the man’s behavior so suspicious that he wonders at the time if he could be a terrorist.
FBI and United Airlines Not that Interested - Several days after 9/11, McAleer will contact the FBI’s Chicago field office about the incident. An FBI agent takes his information, but does not seem very interested or even comprehending about the jump seat idea. Several days after that, McAleer describes the incident to a United Airlines flight attendant supervisor. After conferring with a manager, the supervisor tells him: “Do not talk to the FBI again. I went to [United Airlines assistant station manager] Mitch Gross and he told me to tell you not to talk to the FBI again. If you have any concerns you can call the [United Airlines] Crisis Center. The FBI agents are working on the case.” McAleer gives the information by phone to the Crisis Center, but he still is unsatisfied. He later tells the story to Gross, and Gross tells him, “You are not to talk to anyone about this.” On September 27, 2001, McAleer will read a local newspaper article that shows the pictures of all of the 9/11 hijackers for the first time (see September 27, 2001), and he quickly concludes that hijacker Fayez Ahmed Banihammad was the suspicious man who had flown on Flight 514. McAleer continues to try to raise the issue, for instance with United Airlines corporate security, but without much success.
FBI Stops Media Coverage - Eventually, McAleer will come in contact with a USA Today reporter named Blake Morrison. After checking with the FBI, Morrison decides to write a story about McAleer’s experience. However, at the last minute, the FBI contacts Morrison and asks him not to run the article. As a result, the article only runs in the international edition of USA Today, on June 12, 2002. Morrison later tells McAleer that an FBI source told him that Banihammad’s name was not on the flight manifest. This does not surprise McAleer, since people using jump seat passes or companion passes are not usually on the manifest. The 9/11 Commission will not mention McAleer’s story at all, and will dismiss the jumpseating issue in general. [9/11 Commission, 8/12/2003 pdf file]
Legal Implications - There will be reports that other 9/11 hijackers used test flights to try to get into cockpits, and some tried to sit in jump seats (see November 23, 2001 and November 23, 2001). There will also be reports that jump seats were used by the hijackers in the 9/11 attacks (see September 24, 2001 and November 23, 2001). Jumpseating will become a contentious issue, because if it could be shown that the 9/11 hijackers were able to get into cockpits using jump seats, American Airlines and United Airlines could be sued for significant damages. In fact, McAleer’s account will later be used in a 9/11 negligence lawsuit against United Airlines. In 2011, it will be reported that attorneys in the lawsuit are attempting to depose the agents who interviewed McAleer, but the Justice Department is refusing to let the agents testify.

[Source: Publicity photo]Leslie Robertson, one of the two original structural engineers for the World Trade Center, is asked at a conference in Frankfurt, Germany what he had done to protect the Twin Towers from terrorist attacks. He replies, “I designed it for a 707 to smash into it,” though does not elaborate further. [Chicago Tribune, 9/12/2001; Knight Ridder, 9/12/2001] The Twin Towers were in fact the first structures outside the military and nuclear industries designed to resist the impact of a jet airplane. [Robertson, 3/2002; Federal Emergency Management Agency, 5/1/2002, pp. 1-17] The Boeing 707 was the largest in use when the towers were designed. Robertson conducted a study in late 1964, to calculate the effect of a 707 weighing 263,000 pounds and traveling at 180 mph crashing into one of the towers. He concluded that the tower would remain standing. However, no official report of his study has ever surfaced publicly. [Glanz and Lipton, 2004, pp. 138-139, 366] A previous analysis, carried out early in 1964, calculated that the towers would handle the impact of a 707 traveling at 600 mph without collapsing (see February 27, 1993). In 2002, though, Robertson will write, “To the best of our knowledge, little was known about the effects of a fire from such an aircraft, and no designs were prepared for that circumstance.” [Robertson, 3/2002] The planes that hit the WTC on 9/11 are 767s, which are almost 20 percent heavier than 707s.

On this day, he runs into Rodney Leibowitz, a friend of his, and complains to him about the very poor standard of security at the Twin Towers. For instance, he mentions that, even though the complex receives bomb threats on a daily basis, its telephone system does not feature caller identification.

Hijackers Mohamed Atta Waleed Alshehri, Wail Alshehri, Abdulaziz Alomari, and Satam Al Suqami presumably are killed instantly, and many more in the tower will die over the next few hours. Seismic records pinpoint the crash at 26 seconds after 8:46 a.m. [CNN, 9/12/2001; New York Times, 9/12/2001; North American Aerospace Defense Command, 9/18/2001; USA Today, 12/20/2001; Federal Emergency Management Agency, 5/1/2002, pp. 1-10; New York Times, 5/26/2002; USA Today, 8/13/2002; Associated Press, 8/21/2002; Newsday, 9/10/2002] The NIST report states the crash time to be 8:46:30. [National Institute of Standards and Technology, 9/2005, pp. 19] The 9/11 Commission Report states the crash time to be 8:46:40. [9/11 Commission, 7/24/2004, pp. 7] Investigators believe the plane still has about 10,000 gallons of fuel (see 8:57 a.m. September 11, 2001). [New York Times, 5/26/2002] The plane strikes the 93rd through 99th floors in the 110-story building. No one above the crash line survives; approximately 1,360 people die. Below the crash line, approximately 72 die and more than 4,000 survive. Both towers are slightly less than half full at the time of the attack, with between 5,000 to 7,000 people in each tower. This number is lower than expected. Many office workers have not yet shown up to work, and tourists to the observation deck opening at 9:30 A.M. have yet to arrive. [USA Today, 12/20/2001; National Institute of Standards and Technology, 9/2005, pp. 20-22] The impact severs some columns on the north side of the North Tower. Each tower is designed as a “tube-in-tube” structure and the steel columns which support its weight are arranged around the perimeter and in the core. The plane, which weighs 283,600 lb and is traveling at an estimated speed of around 430 mph (see October 2002-October 2005), severs 35 of the building’s 236 perimeter columns and damages another two. The damage to the South Tower’s perimeter will be similar (see 9:03 a.m. September 11, 2001). [National Institute of Standards and Technology, 9/2005, pp. 5-9, 20, 22] The perimeter columns bear about half of the tower’s weight, so this damage reduces its ability to bear gravity loads by about 7.5 percent. [National Institute of Standards and Technology, 9/2005, pp. 6] The actual damage to the 47 core columns is not known, as there are no photographs or videos of it, but there will be much speculation about this after 9/11. It will be suggested that some parts of the aircraft may have damaged the core even after crashing through the exterior wall. According to the National Institute of Standards and Technology (NIST): “Moving at 500 mph, an engine broke any exterior column it hit. If the engine missed the floor slab, the majority of the engine core remained intact and had enough residual momentum to sever a core column upon direct impact.” [National Institute of Standards and Technology, 9/2005, pp. 107] According to NIST’s base case computer model, three of the core columns are severed and another ten suffer some damage. [National Institute of Standards & Technology, 9/2005, pp. 189 pdf file] If this is accurate, it means that the impact damage to the core reduces the Tower’s strength by another approximately 7.5 percent, meaning that the building loses about 15 percent of its strength in total. This damage will be cited after 9/11 by NIST and others researchers as an event contributing to the building’s collapse (see October 23, 2002 and October 19, 2004). In addition, some of the fireproofing on the steel columns and trusses may be dislodged. The original fireproofing on the fire floors was mostly Blazeshield DC/F, but some of the fireproofing on the flooring has recently been upgraded to Blazeshield II, which is about 20 percent denser and 20 percent more adhesive. [National Institute of Standards & Technology, 9/2005, pp. xxxvi, 83 pdf file] Photographs and videos of the towers will not show the state of fireproofing inside the buildings, but NIST will estimate the damage to it using a computer model. Its severe case model (see (October 2002-October 2005)) will predict that 43 of the 47 core columns are stripped of their fireproofing on one or more floors and that fireproofing is stripped from trusses covering 60,000 ft2 of floor area, the equivalent of about one and a half floors. NIST will say that the loss of fireproofing is a major cause of the collapse (see April 5, 2005), but only performs 15 tests on fireproofing samples (see October 26, 2005). [National Institute of Standards and Technology, 9/2005, pp. 23] According to NIST, more fireproofing is stripped from the South Tower (see 9:03 a.m. September 11, 2001).

Mike Pecoraro.Mike Pecoraro. [Source: Chief Engineer]Mike Pecoraro, an engineer who is part of the crew that services the WTC complex, is at work in the mechanical shop in the second subbasement of the north WTC tower when it is hit. When the room he is in starts filling with white smoke and he can smell kerosene (jet fuel), he heads up stairs with a co-worker towards a small machine shop on the C level. Yet, he says, “There was nothing there but rubble. We’re talking about a 50 ton hydraulic press—gone!” He then heads for the parking garage, yet finds that “there were no walls, there was rubble on the floor, and you can’t see anything.” He ascends to the B level where he sees a 300-pound steel and concrete fire door, which is lying on the floor, wrinkled up “like a piece of aluminum foil.” Pecoraro recalls seeing similar things at the Center when it was bombed in 1993 and is therefore convinced that a bomb has gone off this time. When he makes it into the main lobby, he sees massive damage: “The whole lobby was soot and black, elevator doors were missing. The marble was missing off some of the walls. 20-foot section of marble, 20 by 10 foot sections of marble, gone from the walls.… Broken glass everywhere, the revolving doors were all broken and their glass was gone.” Pecoraro says he only later hears that “jet fuel actually came down the elevator shaft, blew off all the (elevator) doors and flames rolled through the lobby. That explained all the burnt people and why everything was sooted in the lobby.” He makes it out of the North Tower before it collapses. [Chief Engineer, 8/1/2002]

It is shown as evidence in the 2006 Zacarias Moussaoui trial. [Source: FBI]The passport of 9/11 hijacker Satam Al Suqami is reportedly found a few blocks from the World Trade Center. [ABC News, 9/12/2001; Associated Press, 9/16/2001; ABC News, 9/16/2001] Barry Mawn, the director of the FBI’s New York office, will say that police and the FBI found it during a “grid search” of the area. [CNN, 9/18/2001] However, according to the 9/11 Commission, the passport is actually discovered by a male passer-by who is about 30 years old and wearing a business suit. The man gives it to New York City Police Department Detective Yuk H. Chin shortly before 9:59 a.m., when the South Tower of the WTC collapses. The man leaves before he is identified. Chin, according to the 9/11 Commission, will give the passport to the FBI later in the day. [9/11 Commission, 1/26/2004; 9/11 Commission, 8/21/2004, pp. 40 pdf file] An FBI timeline concerned with the 9/11 hijackers will state that the passport is found by a civilian “on the street near [the] World Trade Center,” and is “soaked in jet fuel.” [Federal Bureau of Investigation, 10/2001, pp. 291 pdf file] According to FBI agent Dan Coleman, Al Suqami’s passport is handed to a New York City detective who is “down there, trying to talk to people as they were coming out of the buildings.” By the time the detective looks up again after receiving the passport, the man who handed it to him has run off, “which doesn’t make sense,” Coleman will say. The passport is then given to a detective on the Joint Terrorism Task Force. Coleman will say that by this evening, “we realized… that this was the passport of one of the people that headquarters had identified as one of the 19 probable hijackers.” [France 5, 3/14/2010] Investigative journalist Nick Davies will later write that he talked to “senior British sources who said they believed that the discovery of a terrorist’s passport in the rubble of the Twin Towers in September 2001 had been ‘a throwdown,’ i.e. it was placed there by somebody official.” [Davies, 2009, pp. 248] The Guardian will comment, “The idea that Mohamed Atta’s passport had escaped from that inferno unsinged [tests] the credulity of the staunchest supporter of the FBI’s crackdown on terrorism.” (Note that, as in this Guardian account, the passport will frequently be mistakenly referred to as belonging to Atta, not Al Suqami.)

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).

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

Brian Clark.Brian Clark. [Source: CTV]Brian Clark, the executive vice president of brokerage firm Euro Brokers, was on the 84th floor of the South Tower, where his firm’s offices are, when Flight 175 crashed into it. He had headed out, going down Stairway A, which is the only staircase in the tower that remains intact from top to bottom, and was soon joined by Stanley Praimnath, who also works in the South Tower. They reach a point that Clark later guesses to have been around the 77th or 78th floor, where the stairway walls are cracked, allowing them to look through. This would be around the lower end of the floors where the plane impacted. However, Clark sees no large fire. He later says, “[Y]ou could look through the cracks and see flames. They were just quietly licking up, not a roaring inferno. And there was some smoke there, but again I think the stairs were pressurized, pushing the air out so we had less smoke in the stairway than you might imagine.” [BBC, 3/7/2002; New York Times, 5/26/2002; Sun, 9/6/2002; 9/11 Commission, 5/18/2004] This apparently contradicts later claims that the tower was subjected to “extreme fires” prior to its collapse. [New York Times, 10/20/2004] Firefighter Orio Palmer will make it up to this level of the tower later on, and also report only finding small fires there (see 9:52 a.m. September 11, 2001). Clark and Praimnath continue down the stairs and make it out just minutes before the collapse. They are two of only four people who were at or above the impact zone after Flight 175 hit, who are able to escape from the South Tower. [CNN, 9/9/2002] A further 14 people are able to get out of the building from its 78th floor, which is the lower part of the crash zone. [Dwyer and Flynn, 2005, pp. 255]

NIST will estimate that less than 1,500 gallons were consumed in a fireball inside the tower and 910 to 2,275 gallons were consumed in the fireballs outside the building. Approximately 6,100 gallons therefore splashed onto the office furnishings and started fires on various floors. However, after the jet fuel is used up, office fires burn until the building collapses. NIST will calculate that there were about four pounds per square foot of combustibles in the office space, or about 60 tons per floor. Offices in the WTC actually had fewer combustibles than other similar spaces due to the small number of interior walls and limited bookshelf space.

The exterior wall on the east side of the World Trade Center’s South Tower apparently bows before the building collapses. The first inquiry into the collapse, by the Federal Emergency Management Agency and the American Society of Civil Engineers, states that the perimeter walls bow outward. “Expansion of floor slabs and framing results in outward deflection of columns and potential overload,” the investigation concludes. [Federal Emergency Management Agency, 5/1/2002, pp. 2-25] However, a subsequent report by the National Institute of Standards and Technology states that the east wall of the South Tower bows inward. In places the wall is said to bow inward by between seven and nine inches at floor 80, and NIST interprets this bowing to mean that the floors must be sagging. NIST will find that the sagging and bowing are two of the seven major factors that led to the collapse of each tower, as the bowing walls are no longer able to support their share of the buildings’ weight, causing the buildings to tilt and the upper sections to fall. [National Institute of Standards and Technology, 9/2005, pp. 43-46, 87] A wall in the North Tower also apparently bows before the building collapses (see 10:23 a.m. September 11, 2001).

A director at Boston’s Logan Airport receives the passenger manifests for Flight 11 and Flight 175, and reportedly is able to quickly single out the names of the five hijackers on each of these flights. Ed Freni, the director of aviation operations at Logan, had phoned his contacts at American and United Airlines who are based at the airport roughly around 9:00-9:15. He had requested the manifests for the two hijacked planes that took off from there (see (9:00 a.m.-9:15 a.m.) September 11, 2001). Several pages with names listed in long columns now roll out of the fax machine in the Massachusetts Port Authority (Massport) aviation office at Logan, where Freni recently arrived. Freni looks over the manifest for Flight 11. Aware that Arab men attacked the World Trade Center in 1993, he searches for any Arabic names. According to author Tom Murphy, he circles the names of the five men later accused of being the plane’s hijackers: “In 2A and 2B, he circled two, both W. Alshehri. In 8D, M. Atta, and 8G, A. Alomari. In 10B, he circled S. Al Suqami.” None of the names of the other individuals on the plane appear suspicious to him. Freni then looks over the manifest for Flight 175. Again, according to Murphy, he singles out the names of the men later accused of being the plane’s hijackers: “He circled F. Alquadibanihammad [presumably Fayez Ahmed Banihammad], A. Alghamdi, H. Alghamdi, M. Alshehri, and M. Alshehhi.” Freni asks John Duval, Logan’s deputy director of operations who is with him in the aviation office, “FBI here yet?” Duval replies, “They’re on the way over from downtown.” Freni says, “Tell ‘em we got their guys.” [Murphy, 2006, pp. 34-36] However, at 10:59 a.m., the FBI’s Chicago command post will receive a copy of the manifest for Flight 175, and, according to an FBI document, this will have six Muslim names on it—one more than Freni reportedly singles out. [Federal Bureau of Investigation, 9/12/2001 pdf file] Presumably the sixth Muslim name is that of Touri Bolourchi, a nurse originally from Iran. [New York Times, 6/30/2002] There were also at least another two passengers on Flight 11 with names that might appear to be Arabic, yet that Freni apparently does not single out: Waleed Iskandar was a Lebanese management consultant. [Palo Alto Weekly, 12/12/2001; Associated Press, 9/11/2002] And Rahma Salie was an IT consultant of Sri Lankan descent. [Independent, 10/11/2001; New York Times, 7/14/2002]

Shortly before Flight 77 hits the Pentagon, Washington’s Dulles Airport, from where it had departed, is “locked down” by the FAA, and many FBI and INS agents arrive, but their behavior is considered odd. Ed Nelson, a security manager at the airport, thinks something is not “adding up,” due to the unusual questions his employees are being asked: “They were not asking about the hijackers—they were focusing on what my screeners might have done wrong. It was as if they were working off a script.” FBI agents will later confirm this, and an FBI supervisor will say: “The orders came from headquarters through the local Washington-area FBI field offices and the Joint Task Force on Terrorism. The teams of agents were told to ‘get the screeners to admit they had violated FAA recommended procedures.’” [Trento and Trento, 2006, pp. 36]

Lamberth will later report being stuck in a carpool lane near the Pentagon when it is hit. With his car enveloped in smoke, he calls US marshals to help him get to his office. Lamberth will later say that by the time officers reached him, “I had approved five FISA coverages [warrants] on my cellphone.” [Associated Press, 6/24/2007] Presumably this represents the start of a flurry of surveillance activity in response to the 9/11 attacks, but it is not known who was to be monitored or how their names were learned and acted on so quickly.

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

[Source: Cameraplanet]Video footage later reveals that in the minutes immediately before the collapse of the WTC’s South Tower, a stream of molten metal starts pouring out of a window opening around the northeast corner of its 80th floor. FEMA later suggests that this is “possibly aluminum from the airliner,” and comments, “This is of particular interest because, although the building collapse appears to have initiated at this floor level, the initiation seems to have occurred at the southeast rather than the northeast corner.” [Civil Engineering, 5/2002; Federal Emergency Management Agency, 5/1/2002, pp. 2-34; Dwyer and Flynn, 2005, pp. 207] According to the National Institute of Standards and Technology, “The composition of the flowing material can only be the subject of speculation, but its behavior suggests it could have been molten aluminum.” [Pitts, Butler, and Junker, 9/2005, pp. 375] However physics professor Steven E. Jones will in 2006 dispute this, saying that molten aluminum is silvery and never turns yellow, like what is in the video footage. He will instead claim the presence of this molten metal supports the theory that explosives, specifically thermite, are what caused the Twin Towers to collapse. He says thermite can cause steel to melt and become yellowish. [Deseret Morning News, 4/10/2006]

The New York Times will report “[N]owhere on the tape is there any indication that firefighters had the slightest indication that the tower had become unstable or that it could fall.” [New York Times, 11/9/2002] Palmer’s communication appears to contradict claims that “extreme fires” contributed to the tower’s collapse.

[Source: John Labriola]In the lobby of Building 7 of the WTC, EMS Division Chief John Peruggia is in discussion with Fire Department Captain Richard Rotanz and a representative from the Department of Buildings. As Peruggia later describes, “It was brought to my attention, it was believed that the structural damage that was suffered to the [Twin] Towers was quite significant and they were very confident that the building’s stability was compromised and they felt that the North Tower was in danger of a near imminent collapse.” Peruggia grabs EMT Richard Zarrillo and tells him to pass on the message “that the buildings have been compromised, we need to evacuate, they’re going to collapse.” Zarrillo heads out to the fire command post, situated in front of 3 World Financial, the American Express Building, where he relays this message to several senior firefighters. He says, “OEM says the buildings are going to collapse; we need to get out.” (OEM is the Mayor’s Office of Emergency Management, which has its headquarters in WTC 7.) Fire Chief Pete Ganci’s response is, “who the f___ told you that?” Seconds later, they hear the noise of the South Tower as it collapses.

bullet Lonnie Penn, another EMT, is outside the Marriott Hotel, which is adjacent to the North Tower. He and his partner “felt the ground shake. You could see the towers sway and then it just came down.” [City of New York, 11/9/2001]
bullet Bradley Mann is at the EMS staging area on Vesey Street. He says, “Shortly before the first tower came down I remember feeling the ground shaking. I heard a terrible noise, and then debris just started flying everywhere.” [City of New York, 11/7/2001]
bullet Battalion Chief Brian O’Flaherty is walking into the lobby of the Marriott Hotel. He says, “I hear a noise. Right after that noise, you could feel the building start to shudder, tremble, under your feet.” He then hears the “terrible noise” of the South Tower collapsing. [City of New York, 1/9/2002] Witnesses will also notice the ground shaking before the North Tower collapses (see Shortly Before 10:28 a.m. September 11, 2001).

Mayor Rudolph Giuliani will become well known for his walking press conferences in the middle of the 9/11 crisis.Mayor Rudolph Giuliani will become well known for his walking press conferences in the middle of the 9/11 crisis. [Source: Time Magazine/ Salient Stills]Between 9:25 a.m. and 9:45 a.m., one senior New York fire chief recommends to the Fire Department Chief of Department that there might be a WTC collapse in a few hours, and, therefore, fire units probably shouldn’t ascend much above the sixtieth floor (presumably this assumes the collapse would be gradual so those on lower floors would still have time to evacuate). This advice is not followed or not passed on. Apparently, no other senior fire chiefs mention or foresee the possibility of the WTC towers falling. [9/11 Commission, 5/19/2004] However, New York City Mayor Rudolph Giuliani later recounts, “I went down to the scene and we set up headquarters at 75 Barclay Street, which was right there, with the police commissioner, the fire commissioner, the head of emergency management, and we were operating out of there when we were told that the World Trade Center was going to collapse. And it did collapse before we could actually get out of the building, so we were trapped in the building for ten, 15 minutes, and finally found an exit and got out, walked north, and took a lot of people with us.” [ABC News, 9/11/2001] As can be seen by another account of similar events, this happens before the first WTC tower falls, not the second. [9/11 Commission, 5/19/2004] It is not clear who tells Giuliani to evacuate when no fire chiefs were considering the possibility of an imminent collapse. However, an EMT is also given a message around this time, warning that the towers are going to collapse. The origin of this information is apparently the Mayor’s Office of Emergency Management, so this may also have been from where Giuliani heard of the imminent collapse (see (Before 9:59 a.m.) September 11, 2001).

bullet Police officer Sue Keane, who is an Army veteran, is located in the north WTC tower: “[I]t sounded like bombs going off. That’s when the explosions happened.… It started to get dark, then all of a sudden there was this massive explosion.” [Hagen and Carouba, 2002, pp. 65]
bullet Firefighter Keith Murphy, who is in the lobby of the North Tower: “[T]he first thing that happened, which I still think is strange to me, the lights went out.… I had heard right before the lights went out, I had heard a distant boom boom boom, sounded like three explosions.… At the time, I would have said they sounded like bombs, but it was boom boom boom and then the lights all go out.… I would say about 3, 4 seconds, all of a sudden this tremendous roar.” [City of New York, 12/5/2001]

Deputy Fire Commissioner Thomas Fitzpatrick.Deputy Fire Commissioner Thomas Fitzpatrick. [Source: City of New York]Numerous witnesses to the collapse of the south WTC tower think it resembles a demolition using explosives. Some initially believe this is what is occurring:
bullet Reporter John Bussey watches the collapse from the Wall Street Journal’s offices across the street from the WTC. He says, “I… looked up out of the office window to see what seemed like perfectly synchronized explosions coming from each floor, spewing glass and metal outward. One after the other, from top to bottom, with a fraction of a second between, the floors blew to pieces.” [Wall Street Journal, 9/12/2001]
bullet Deputy Fire Commissioner Thomas Fitzpatrick: “I remember seeing, it looked like sparkling around one specific layer of the building.… Then the building started to come down. My initial reaction was that this was exactly the way it looks when they show you those implosions on TV.” [City of New York, 10/1/2001]
bullet Assistant Fire Commissioner Stephen Gregory: “I saw low-level flashes. In my conversation with Lieutenant Evangelista… he questioned me and asked me if I saw low-level flashes in front of the building, and I agreed with him… I saw a flash flash flash and then it looked like the building came down.… You know like when they demolish a building, how when they blow up a building, when it falls down? That’s what I thought I saw.” [City of New York, 10/3/2001]
bullet Firefighter Richard Banaciski: “It seemed like on television they blow up these buildings. It seemed like it was going all the way around like a belt, all these explosions.” [City of New York, 12/6/2001]
bullet Firefighter Joseph Meola: “As we are looking up at the building, what I saw was, it looked like the building was blowing out on all four sides. We actually heard the pops.… You thought it was just blowing out.” [City of New York, 12/11/2001]
bullet Fire Chief Frank Cruthers: “[T]here was what appeared to be at first an explosion. It appeared at the very top, simultaneously from all four sides, materials shot out horizontally. And then there seemed to be a momentary delay before you could see the beginning of the collapse.” [City of New York, 10/31/2001]
bullet Battalion Chief Brian Dixon: “I was watching the fire… the lowest floor of fire in the South Tower actually looked like someone had planted explosives around it because the whole bottom I could see—I could see two sides of it and the other side—it just looked like that floor blew out.… I thought, geez, this looks like an explosion up there, it blew out.” [City of New York, 10/25/2001]
bullet Firefighter Timothy Burke: “Then the building popped, lower than the fire… I was going oh, my god, there is secondary device because the way the building popped I thought it was an explosion.” [City of New York, 1/22/2002]
bullet Firefighter Edward Cachia: “It actually gave at a lower floor, not the floor where the plane hit, because we originally had thought there was like an internal detonation explosives because it went in succession, boom, boom, boom, boom, and then the tower came down.” [City of New York, 12/6/2001]
bullet Firefighter Kenneth Rogers: “[T]here was an explosion in the South Tower… I kept watching. Floor after floor after floor. One floor under another after another and when it hit about the fifth floor, I figured it was a bomb, because it looked like a synchronized deliberate kind of thing.” [City of New York, 12/10/2001]
bullet Reporter Beth Fertig: “The tower went down perfectly straight, as if a demolition crew had imploded it. I wondered if it was being brought down deliberately.” [Gilbert et al., 2002, pp. 78]
bullet Paramedic Daniel Rivera: “[D]o you ever see professional demolition where they set the charges on certain floors and then you hear ‘Pop, pop, pop, pop, pop’? That’s exactly what—because I thought it was that.” [City of New York, 10/10/2001]
bullet Battalion Chief Dominick DeRubbio: “It was weird how it started to come down. It looked like it was a timed explosion.” [City of New York, 10/12/2001]
bullet The Guardian will report that police on the scene said the collapse “looked almost like a ‘planned implosion’ designed to catch bystanders watching from the street.” [Guardian, 9/12/2001]
However, the National Institute of Standards and Technology, which conducts a three-year study of the WTC collapses, will reject suggestions that the WTC towers were brought down with explosives (see August 30, 2006). CTV will assert, “[F]lashes of light that seemed to indicate bombs detonating were not explosions. They were pockets of airs being forced out of windows as the sagging floors pushed downward.” [CTV, 9/12/2006]

Shortly after arriving at Washington’s Dulles Airport, from which Flight 77 took off, the FBI confiscates a security tape from a checkpoint through which the hijackers passed before boarding the plane. Airport security manager Ed Nelson will later say: “They pulled the tape right away.… They brought me to look at it. They went right to the first hijacker on the tape and identified him. They knew who the hijackers were out of hundreds of people going through the checkpoints. They would go ‘roll and stop it’ and showed me each of the hijackers.… It boggles my mind that they had already had the hijackers identified.… Both metal detectors were open at that time, and lots of traffic was moving through. So picking people out is hard.… I wanted to know how they had that kind of information. So fast. It didn’t make sense to me.” [Trento and Trento, 2006, pp. 37] Some of the hijackers are identified on the passenger manifests around this time (see (9:59 a.m.) September 11, 2001), and this knowledge is disseminated in the US intelligence community (see (After 10:06 a.m.) September 11, 2001 and (11:00 a.m.) September 11, 2001).

At some unspecified time after when Flight 93 crashed, CIA Director George Tenet receives the passenger lists for the hijacked planes. He is currently in the CIA’s printing plant, after having evacuated the agency’s headquarters building (see (9:50 a.m.-10:00 a.m.) September 11, 2001). An analyst from the CIA’s Counterterrorist Center (CTC) has raced across to the plant with the list, and says, “Some of these guys on one of the planes are the ones we’ve been looking for in the last few weeks.” He specifically points at the names Khalid Almihdhar and Nawaf Alhazmi (two of the alleged Flight 77 hijackers). According to Tenet, this is “the first time we had absolute proof of what I had been virtually certain of from the moment I heard about the attacks: we were in the middle of an al-Qaeda plot.” Tenet will later say that after the CTC had first “requested passenger lists from the planes that had been turned into weapons that morning… the initial response from some parts of the bureaucracy (which parts since mercifully forgotten) was that the manifests could not be shared with CIA. There were privacy issues involved.” They were only obtained after some “gentle reasoning, and a few four-letter words.” [Tenet, 2007, pp. 167] The agency that provided these lists to the CTC may have been the Customs Office of Intelligence. According to Robert Bonner, the commissioner-designate of US Customs, “through an evaluation of data related to the passengers manifest for the four terrorist hijacked aircraft, Customs Office of Intelligence was able to identify the likely terrorist hijackers. Within 45 minutes of the attacks, Customs forwarded the passenger lists with the names of the victims and 19 probable hijackers to the FBI and the intelligence community” (see (11:00 a.m.) September 11, 2001). [9/11 Commission, 1/26/2004] Counterterrorism “tsar” Richard Clarke will claim he was told as early as 9:59 a.m. that the FBI had received the passenger manifests from the airlines (see (9:59 a.m.) September 11, 2001).

The exterior wall on the south side of the World Trade Center’s North Tower apparently bows before the building collapses. The first inquiry into the collapse, by the Federal Emergency Management Agency and the American Society of Civil Engineers, states that the perimeter walls bow outward (see (9:21 a.m.-9:59 a.m. September 11, 2001)). However, a subsequent report by the National Institute of Standards and Technology states that the south wall of the North Tower bows inward. In places the wall is said to bow inward by approximately 55 inches at floor 97, and NIST interprets this bowing to mean that the floors must be sagging. NIST will find that the sagging and bowing are two of the seven major factors that led to the collapse of each tower, as the bowing walls are no longer able to support their share of the buildings’ weight, causing the buildings to tilt and the upper sections to fall.

Almost all the occupants of the North Tower who are able to evacuate the building have done so. Only 107 occupants who were below the impact floors remain in the building, while around 7,400 have escaped. However, 1,355 building occupants in or above the impact zone have either already died or perish in the collapse, as do many emergency workers. Overall, 99 percent of building occupants below the impact floors escape to safety.

bullet EMS Captain Karin Deshore: “Somewhere around the middle of the World Trade Center, there was this orange and red flash coming out. Initially it was just one flash. Then this flash just kept popping all the way around the building and that building had started to explode. The popping sound, and with each popping sound it was initially an orange and then a red flash came out of the building and then it would just go all around the building on both sides as far as I could see.

The team studying the WTC collapses for the American Society of Civil Engineers (ASCE) and the Federal Emergency Management Agency (FEMA) will later observe that the antenna on WTC 1 began to fall before the exterior of the building: “Review of videotape recordings of the collapse taken from various angles indicates that the transmission tower on top of the structure began to move downward and laterally slightly before movement was evident at the exterior wall. This suggests that collapse began with one or more failures in the central core area of the building.” [Federal Emergency Management Agency, 5/1/2002, pp. 2-27] In a program featuring some members of the FEMA/ASCE team, the BBC will comment: “The mast was directly supported by the tower’s inner core. The way it fell suggests it was failure of the inner core that began the collapse, whereas in the South Tower it had been the outer walls.” [BBC, 3/7/2002]

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).

Terri Rizzuto.Terri Rizzuto. [Source: ReclaimingTheSky.com]A United Airlines manager finds that a gate agent has already singled out boarding passes belonging to four suspicious passengers who were on Flight 93. Terri Rizzuto is the United Airlines station manager at Newark Airport, from where Flight 93 departed. Some time after hearing that this plane has crashed, she speaks on the phone with the FBI, which is requesting the plane’s manifest and its Passenger Name Record (PNR). After arranging permission to release these, she goes to Gate 17, from where she knows Flight 93 departed, wanting to talk to her staff there. When she arrives, a supervisor hands her four boarding passes. The supervisor tells her they are “The men, who did this maybe,” and points her toward one of the gate agents who had boarded the passengers onto the flight. When Rizzuto asks the gate agent, “How do you know?” he replies: “They were too well-dressed. Too well-dressed for that early in the morning. And their muscles rippled below their suits.… [A]nd their eyes.” [Murphy, 2006, pp. 71-73] However, this report of men with rippling muscles contradicts the 9/11 Commission’s description of the so-called “muscle” hijackers (i.e. the non-pilot hijackers) on the four targeted planes: They “were not physically imposing,” with the majority of them being “slender in build.” [9/11 Commission, 6/16/2004]

Wallace Miller.Wallace Miller. [Source: Steve Mellon / Pittsburgh Post-Gazette]Wallace Miller, the coroner of Somerset County, is one of the first people to arrive at the Flight 93 crash scene. However, he is surprised by the absence of human remains there. He later says, “If you didn’t know, you would have thought no one was on the plane. You would have thought they dropped them off somewhere.” [Longman, 2002, pp. 217] The only recognizable body part he sees is a piece of spinal cord with five vertebrae attached. He will later tell Australian newspaper The Age, “I’ve seen a lot of highway fatalities where there’s fragmentation. The interesting thing about this particular case is that I haven’t, to this day, 11 months later, seen any single drop of blood. Not a drop.” [Age (Melbourne), 9/9/2002] Dave Fox, a former firefighter, also arrives early at the crash scene, but sees just three chunks of human tissue. He says, “You knew there were people there, but you couldn’t see them.” [Pittsburgh Tribune-Review, 9/11/2002] Yet, in the following weeks, hundreds of searchers are able to find about 1,500 scorched human tissue samples, weighing less than 600 pounds—approximately eight percent of the total body mass on Flight 93. Months after 9/11, more remains are found in a secluded cabin, several hundred yards from the crash site. [Washington Post, 5/12/2002]

Logo of the National Air Traffic Controllers Association.Logo of the National Air Traffic Controllers Association. [Source: National Air Traffic Controllers Association]Several air traffic controllers at the FAA’s New York Center and a union official representing them express concern that the controllers are going to be recorded recalling their experiences of the morning’s attacks, but are persuaded to go ahead with the recording. [9/11 Commission, 10/1/2003 pdf file; US Department of Transportation, 5/4/2004 pdf file; Washington Post, 5/7/2004] Mike McCormick, the New York Center manager, has directed that six controllers who communicated with, or tracked, the first two hijacked aircraft participate in a session where they are recorded giving their personal accounts of what happened. [Washington Post, 5/6/2004; Air Safety Week, 5/17/2004]
Controllers Apprehensive - According to McCormick, before the session commences there is a general concern among these controllers. He will later tell the 9/11 Commission that they “didn’t want to put things in a formal way that would be used in an investigation. There was also some worry about who would receive the tape.”
Local Union President Concerned - McCormick consults with Mark DiPalmo, the local president of the National Air Traffic Controllers Association (NATCA)—the air traffic controllers’ union. DiPalmo is concerned because the tape recording of statements is not a standard procedure. McCormick assures him that the tape will be available only to law enforcement officers, will only serve as a temporary measure until written statements have been prepared, and the controllers will be able to use their taped statements to help them prepare written ones. [9/11 Commission, 10/1/2003 pdf file; US Department of Transportation, 5/4/2004 pdf file; New York Times, 5/6/2004] Ruth E. Marlin, the executive vice president of NATCA, will later say she cannot address the question of why DiPalmo wants the tape to be “temporary.” She will say, however, that if she were in his position, “my concern would be that if tapes were saved permanently, they might be subject to FOIA [Freedom of Information Act] request, and then controllers would be subject to hearing their own voices recounted on television over and over again.” [Washington Post, 5/7/2004]
Controllers and Union President Consent - The controllers are reassured that the tape with their recorded statements on will not be used for disciplinary purposes, and will be strictly for use only by law enforcement personnel. [9/11 Commission, 10/1/2003 pdf file] DiPalmo agrees to the recording of the controllers on the condition that the tape is only a temporary record until written statements are obtained, after which it should be destroyed. The recording session commences at 11:40 a.m. (see 11:40 a.m. September 11, 2001) and the resulting tape will be destroyed several months later (see Between December 2001 and February 2002).

A number of air traffic controllers at the FAA’s New York Center provide accounts of their experiences of interacting with, or tracking, two of the hijacked aircraft, on a tape recording that will later be destroyed by one of the center’s managers. [New York Times, 5/6/2004; Washington Post, 5/7/2004; Air Safety Week, 5/17/2004]
Manager Directs Colleague to Record Controllers - Mike McCormick, the New York Center manager, directs the taping. He will later say he does so because he wants a contemporaneous recording of the controllers’ accounts that will be immediately available for law enforcement efforts, in case agencies like the FBI show up at the center. He is also concerned that the controllers might be taking stress-induced sickness leave in response to the attacks. They would therefore be unavailable to give conventional written witness statements in a timely manner, and their recollections would be less clear when they returned from leave. McCormick tells Kevin Delaney, the center’s quality assurance manager, to record the controllers’ statements, and a tape recorder is then set up to do this. [9/11 Commission, 10/1/2003 pdf file; US Department of Transportation, 5/4/2004 pdf file; Air Safety Week, 5/17/2004]
Controllers Gathered Together - At least six of the center’s air traffic controllers are gathered in a room at the center nicknamed the “Bat Cave” for the fact-finding session. [US Department of Transportation, 5/4/2004 pdf file; New York Times, 5/6/2004] These controllers and a union official representing them were concerned about the controllers being recorded, but have been persuaded to go ahead with the session (see (Shortly Before 11:40 a.m.) September 11, 2001). [9/11 Commission, 10/1/2003 pdf file; US Department of Transportation, 5/4/2004 pdf file; Washington Post, 5/7/2004]
Controllers Describe Experiences - Beginning at 11:40 a.m., a recording is made on a single, standard cassette tape. The controllers, who were involved in working radar positions during the hijackings and crashes of the first two targeted aircraft, Flight 11 and Flight 175, are asked to make statements. According to Mark DiPalmo, the local president of the National Air Traffic Controllers Association, “We sat everyone in a room, went around the room, said, ‘What do you remember?’” The controllers give their statements in the group setting, with a microphone being passed from one of them to the next. They describe their actions interacting with, or tracking, the two hijacked aircraft. According to DiPalmo, the session is informal, and sometimes more than one person is speaking at a time. The resulting tape lasts about an hour, with each recorded statement lasting about five to 10 minutes.
Other Employees Present - As well as the six controllers, approximately 10 other FAA employees are present during the session. (A signing-in sheet will show that about 16 center personnel are there. However, some witnesses will later indicate there may be additional individuals who do not sign in.) Two quality assurance specialists take notes, but these are sketchy, amounting to just three pages in total. After the tape of the session has been made, it is logged into the New York Center’s formal record of evidence.
Recording Controllers Not Standard Procedure - Audio taping of witness statements following an accident or incident has not previously been conducted at the New York Center. [US Department of Transportation, 5/4/2004 pdf file; New York Times, 5/6/2004] However, David LaCates, the deputy operations manager there, will tell the 9/11 Commission that, “Since this was an unusual situation,” he believes McCormick wants “an immediate and accurate record of what had happened.” [9/11 Commission, 10/2/2003 pdf file]
FBI Does Not Come to Center - Although McCormick is expecting law enforcement authorities to come to the New York Center quickly, none do. Yet, even though he will later claim he wanted the tape made for the benefit of these authorities, McCormick will not reach out to the FBI himself, nor tell FAA headquarters or regional headquarters that no one has come. [9/11 Commission, 10/1/2003 pdf file; Air Safety Week, 5/17/2004]
Tape Later Destroyed - Despite its evidential value, Delaney will deliberately destroy the tape of the controllers’ statements several months later (see Between December 2001 and February 2002), before anyone has listened to, transcribed, or made a duplicate of it. [US Department of Transportation, 5/4/2004 pdf file; Washington Post, 5/7/2004] Even McCormick will say he never listens to the tape. [9/11 Commission, 10/1/2003 pdf file] Prior to an investigation by the Department of Transportation’s Office of Inspector General in late 2003 and early 2004 (see May 6, 2004), apparently no one outside the New York Center will be aware of the tape’s existence or its destruction.

One day after 9/11, the New York Times will report that FBI agents in Florida investigating the hijackers quickly “descended on flight schools, neighborhoods and restaurants in pursuit of leads.” At one flight school, “students said investigators were there within hours of Tuesday’s attacks.” [New York Times, 9/13/2001] Also on September 12, the Times will report, “Authorities said they had also identified accomplices in several cities who had helped plan and execute Tuesday’s attacks. Officials said they knew who these people were and important biographical details about many of them. They prepared biographies of each identified member of the hijack teams, and began tracing the recent movements of the men.” [New York Times, 9/13/2001] In September 2002, 9/11 victim’s relative Kristen Breitweiser, testifying before the 9/11 Congressional Inquiry, will cite these news reports and will ask, “How did the FBI know exactly where to go only a few hours after the attacks? How did they know which neighborhoods, which flight schools and which restaurants to investigate so soon in the case?… How are complete biographies of the terrorists, and their accomplices, created in such short time? Did our intelligence agencies already have open files on these men? Were they already investigating them? Could the attacks of September 11th been prevented?” [US Congress, 9/18/2002] In at least some cases, it appears that US intelligence did quickly access existing files on the hijackers. The Washington Post reports, “In the hours after Tuesday’s bombings, investigators searched their files on [Satam] Al Suqami and [Ahmed] Alghamdi, noted the pair’s ties to [Nabil] al-Marabh and launched a hunt for him.” A top Customs official claims that by checking flight manifests and comparing them with other information such as watch lists, he is able to determine the names of all 19 hijackers by 11:00 a.m.(see (11:00 a.m.) September 11, 2001).

[Toronto Star, 9/15/2001; Toronto Sun, 9/15/2001; Ottawa Citizen, 9/17/2001] Apparently, the man, who identifies himself as an aircraft maintenance engineer in Gaza, Palestine, was supposed to have arrived in the US a few days before but was delayed for unknown reasons. [CBS News, 9/14/2001] A second man was arrested a few days earlier while trying to enter Canada carrying a similar photo. He also possessed maps and directions to the WTC. Both men are soon handed over to the US. [Toronto Star, 9/15/2001] A similar picture of suspected Egyptian al-Qaeda operative Mohammad Zeki Majoub, arrested in Canada in June 2000, in front of a fake WTC backdrop was found in the luggage of one of the US hijackers. [Associated Press, 3/1/2001; Toronto Sun, 9/15/2001] Canadian officials “believe the photos could be calling cards used by the terrorists to identify those involved in plotting the attacks.” [Toronto Sun, 9/15/2001]

A few hours after the attacks, German intelligence intercepts a phone conversation between followers of bin Laden that leads the FBI to search frantically for two more teams of suicide hijackers, according to US and German officials. The Germans overhear the operatives refer to “the 30 people traveling for the operation.” The FBI scours flight manifests and any other clues for more conspirators still at large. [New York Times, 9/29/2001] Two days later, authorities claim to have identified teams of as many as 50 infiltrators who supported or carried out the strikes. About 40 are accounted for as dead or in custody; ten are missing. They also believe a total of 27 suspected operatives received some form of pilot training. This corresponds with many analyses that the attacks required a large support network. [Los Angeles Times, 9/13/2001] Yet there is no evidence that any accomplices in the US shortly before 9/11 have since been arrested or charged.

[Source: Federal Bureau of Investigation]Beginning shortly before midday on September 11, 2001, and continuing until September 12, the FBI conducts a careful search across the grounds of the Pentagon, looking for remnants of the aircraft that hit the building. [PBS, 9/12/2001; Washington Post, 9/12/2001; Goldberg et al., 2007, pp. 159] FBI Special Agent Tom O’Connor is in charge of the initial evidence recovery operation at the Pentagon. His first priority is to locate and gather all the airplane parts and other pieces of evidence from the lawn on the west side of the building. He sends out all available agents to conduct a grid search. The lawn is divided into quadrants, and then agents walk back and forth, sticking a small flag near any evidence they find, getting the evidence photographed in its place, and then scooping it into a bag. [Creed and Newman, 2008, pp. 180] Arlington police officers, military personnel, and others also participate in the search.

[PBS, 9/12/2001] Some pieces of the aircraft that hit the Pentagon are found nearly 1,000 feet away from the building, on the other side of Washington Boulevard. Thousands of tiny pieces of aluminum have also carried forward over the Pentagon, into its center courtyard. Other pieces of debris landed on its roof, along with body parts from at least one victim. [Creed and Newman, 2008, pp. 29] According to the Defense Department’s book about the Pentagon attack, the searchers find “many scraps and a few personal items widely scattered on the grass and heliport. Plane remnants varied from half-dollar size to a few feet long.” [Goldberg et al., 2007, pp. 159] Authors Patrick Creed and Rick Newman will describe: “Agents found what looked like a big Plexiglas windowpane on the lawn, which might have been part of an airplane window, except it was too big.… Somebody suggested it could be one of the blast-proof windows from the Pentagon, somehow blown 500 feet from the building.” [Creed and Newman, 2008, pp. 180]

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).

At FAA headquarters in Washington, DC, David Canoles, the FAA’s manager of air traffic evaluations and investigations, and his staff begin coordinating the collection of forensic evidence that might clarify how the morning’s attacks unfolded. They coordinate the capture and copying of radar track data showing the paths of the four hijacked planes, and obtain air traffic control voice tapes from every facility that had spoken with these planes. FAA Assistant Investigations Manager Tony Mello and other employees will work for most of the afternoon, all night, and part of the following day, gathering data and coordinating with the FBI, Secret Service, Defense Department, White House, and National Transportation Safety Board, making sure these other agencies receive as much evidence as is available. Radar tracks are crudely plotted, showing the flight paths of the four jets, and voice tapes are transcribed. Having been stuck in Chicago when the attacks occurred, (see 8:30 a.m. September 11, 2001), Tony Ferrante, the manager of FAA investigations, will finally arrive at FAA headquarters at 5:00 a.m. on September 12. His first priority is “to ensure that the radar data and voice tapes from every location involved in the attack [are] put under lock and key as soon as possible,” presumably to be kept safe for any investigations. He looks at and listens to the relevant controller tapes, and begins constructing a detailed timeline of the four hijacked aircraft. Along with Tony Mello and others of his staff, Ferrante will spend several days working out the movements of the four planes. FAA radar experts Dan Diggins and Doug Gould will also spend days interpreting the radar tracks of the four planes, piecing together a detailed timeline of their actions from takeoff to crash. [Freni, 2003, pp. 74 and 76-77] The FAA will publish a fairly comprehensive chronology of the hijackings on September 17, though this will not be made public until September 2005.

Due to the chaos and gridlock resulting from the morning’s attacks, the FBI is hampered in mobilizing its investigative operation at the Pentagon. Because the Pentagon is a crime scene, it is the FBI’s job to gather and document every piece of evidence there. [Creed and Newman, 2008, pp. 177] Special Agent Chris Combs, the FBI’s representative at the crash site, has been setting up the FBI operation since arriving at 9:49 a.m. [US Department of Health and Human Services, 7/2002, pp. A20 and 1-1; Creed and Newman, 2008, pp. 178] Since before 10:00 a.m., the bureau’s evidence recovery team has been arriving. But although every available agent has been paged, many are stuck in traffic, and it will take several hours before the entire FBI contingent makes it to the Pentagon. The FBI also has a fleet of sophisticated command vehicles and helicopters, plus other specialized equipment. But even though the crash site is within the “FBI’s backyard,” according to authors Patrick Creed and Rick Newman, by around 12:15 p.m. none of this has arrived yet. The bureau’s rapid-deployment gear, which includes everything needed to gather and document evidence, is stored in a warehouse in Washington, DC. But with traffic in the region at a standstill, it is almost impossible to get this through the streets to the Pentagon. Chris Combs asks his boss at the FBI’s Washington field office if any helicopters are available to get equipment to the Pentagon quickly. But several choppers at the FBI facility in Quantico, just 30 miles south of the Pentagon, are reserved for specific duties during government emergencies and are currently locked down. And according to Creed and Newman, other government helicopters the bureau relies upon for backup are tied up, though what they are being used for is unstated. [US Department of Health and Human Services, 7/2002, pp. A22; Creed and Newman, 2008, pp. 177-179] Furthermore, NBC News has reported that the FBI’s top teams have been away from Washington for the last two days for a major training exercise in California (see 10:03 a.m. September 11, 2001).

[Source: Rudi Williams]Photographers who are taking pictures at the Pentagon, to document the scene of the attack there in as close as possible to its original state, are told to limit what evidence they photograph. FBI Special Agent Tom O’Connor—who is in charge of the initial evidence recovery operation at the Pentagon—and his superiors have put out the word that it is unnecessary to document every piece of the airplane. This is because, reportedly, “the smaller fragments didn’t prove anything, except that there was an airplane there, which was obvious enough from other evidence.” FBI Special Agent Garrett McKenzie, who is coordinating the effort to photograph evidence at the Pentagon, pulls together a dozen photographers for a briefing. He instructs them: “We don’t need to photograph all the plane parts, only unique airplane parts or something specific. Like the pilot’s yoke, or anything with part of a serial number on it. If we have to prove what kind of plane this was, the serial numbers will be what we need.” [Creed and Newman, 2008, pp. 181-183]

He had quickly decided that the area around the Arlington County Fire Department’s incident command post by the Pentagon was too crowded and lacked support facilities.

Deena has now learned of the plane crashing in Pennsylvania, and a police officer staying with her informed her that this was her husband’s plane. The FBI agents spend over an hour with Deena, asking her about her husband and what he’d said in his four calls from Flight 93. [Burnett and Giombetti, 2006, pp. 71-72 and 74-75] She describes to them how Tom called her using his cell phone and told her his flight had been hijacked. In his final call he’d described how a group of the passengers was going to “do something.” She says her husband was a former college football player and very intelligent, so if he’d concluded he was going to die, he would have taken action. [Federal Bureau of Investigation, 9/11/2001 pdf file] Deena remembers that she’d taken notes, writing down the details of her husband’s calls. But she does not want the agents to have these, saying, “You wouldn’t be able to read it anyway.” They do not take the notes with them when they leave. They will return later in the day and tell Deena specifically not to say anything to anyone—especially the media—about her cell phone conversations with her husband, because it is part of their investigation.

The FBI interviews Eric Gill, a security guard at Dulles Airport who may have encountered some of the 9/11 hijackers attempting to access aircraft the night before 9/11 (see Around 8:15 p.m. September 10, 2001). Gill tells the FBI his story, but the FBI fails to show him a video it has found of the hijackers passing through an airport security checkpoint on 9/11, even though it is shown to all his colleagues, except the partner he was on duty with when he saw the hijackers. The FBI also obtains video of two of the hijackers, Khalid Almihdhar and Salem Alhazmi, at Dulles on the day he says he saw another two of them, Nawaf Alhazmi and Marwan Alshehhi, but does not show this video to him and this video will not be publicly mentioned until 2008. It is unclear what the FBI does with logs for a door through which Gill says the hijackers would have passed, but they are not shown to Gill. Two days later, the FBI shows him poor quality photocopied pictures of the hijackers and Gill identifies two of them as the people he saw on September 10, but the FBI then loses interest in him, as they think one of the men he identifies hijacked a plane from Boston, not Dulles. Another man who may have seen the hijackers the night before 9/11, Khalid Mahmoud, is taken away by the INS and does not return, presumably because he has been deported. Gill will speak to a 9/11 Commission staffer on the telephone about 18 months later, but nothing will come of this.

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).

On September 11—after the 9/11 attacks are over—the New York FBI office learns that one of the hijackers was Khalid Almihdhar. One of the FBI agents at the office, Steve Bongardt, had attempted to get permission to search for Almihdhar in late August, but was not allowed to do so. He wrote an e-mail on August 29 (see August 29, 2001) predicting that “someday someone will die… the public will not understand why we were not more effective and throwing every resource we had at certain ‘problems.’” He will later testify that upon seeing Almihdhar’s name on one of the passenger flight manifests, he angrily yells, “This is the same Almihdhar we’ve been talking about for three months!” In an attempt to console him, his boss replies, “We did everything by the book.” Now that Bongardt is allowed to conduct a basic Internet search for Almihdhar that he had been denied permission to conduct before 9/11, he finds the hijacker’s address “within hours.” [Washington Post, 9/21/2002; US Congress, 12/11/2002] The FBI field office in San Diego also was not notified before 9/11 that Almihdhar and Nawaf Alhazmi had been put on a no-fly watch list on August 24, 2001 (see September 4-5, 2001). Bill Gore, the FBI agent running the San Diego office on this day, will later make reference to the fact that Alhazmi’s correct phone number and address were listed in the San Diego phone book, and say: “How could [we] have found these people when we didn’t know we were looking for them? The first place we would have looked is the phone book.… I submit to you we would have found them.” [US Congress, 12/11/2002]

The FBI’s Minneapolis office asks for permission to interview Zacarias Moussaoui a few hours after the end of the 9/11 attacks, but permission is denied, apparently on the grounds that there is no emergency. On 9/11, the office’s counsel, Coleen Rowley, seeks permission from the Acting US Attorney to question Moussaoui about whether al-Qaeda has any further plans to hijack airliners or otherwise attack the US. The next day she asks again; this time the request is sent to the Justice Department. Such questioning would not usually be permitted, but Rowley argues that it should be allowed under a public safety exception. However, permission is denied and Rowley is told that the emergency is over so the public safety exception does not apply. Rowley will later comment: “We were so flabbergasted about the fact we were told no public safety emergency existed just hours after the attacks that my boss advised me to document it in a memo which became the first document in the legal subfile of the FBI’s ‘Penttbom’ case.” [Huffington Post, 5/2/2007] Some sources will suggest that Moussaoui was to be part of a second wave of attacks (see September 5, 2002). He is also an associate of shoe bomber Richard Reid, who will attempt to blow up an airliner later this year (see Mid-2000-December 9, 2000 and December 22, 2001).

The three fighter pilots that launched from Langley Air Force Base to defend Washington, DC (see (9:25 a.m.-9:30 a.m.) September 11, 2001) sign a letter in which they confirm that they did not shoot down any aircraft on 9/11. At some point after the pilots, who belong to the 119th Fighter Wing of the North Dakota Air National Guard, land their fighter jets back at base (see (2:00 p.m.) September 11, 2001), one of them, Captain Craig Borgstrom, speaks over the phone with Major General Larry Arnold, the commanding general of NORAD’s Continental US Region (CONR). According to Borgstrom, who will later recall that Arnold phones him either on September 11 “or in [the] next day or two,” the CONR commander requests “a detailed, in writing, accounting of what happened that day.” Consequently, as another of the three pilots—Major Brad Derrig—will recall, “all three pilots signed a letter to 1st Air Force certifying that they had not shot down an aircraft.” Borgstrom will say he believes that “ammunition records were checked” as a part of the response to the 1st Air Force. [9/11 Commission, 12/1/2003; 9/11 Commission, 12/1/2003] Some early news reports suggested the possibility of a plane having been shot down by the US military (see 11:28 a.m.-11:50 a.m. September 11, 2001), and what appears to be debris from a plane is discovered far away from the main Flight 93 crash site (see (Before 10:06 a.m.) September 11, 2001 and September 13, 2001). [TCM Breaking News, 9/11/2001; CNN, 9/13/2001; Philadelphia Daily News, 11/15/2001; Mirror, 9/12/2002] But in later interviews with the media and the 9/11 Commission, the three 119th Fighter Wing pilots will state that they received no orders to shoot down a commercial airliner, and did not shoot down any planes on 9/11.

Later in the day of 9/11, weapons are found planted on board three US airplanes. A US official will say, “These look like inside jobs.” Time magazine will later report, “Sources tell Time that US officials are investigating whether the hijackers had accomplices deep inside the airports’ ‘secure’ areas.” [Time, 9/22/2001] Penetrating airport security does not appear to have been that difficult: Argenbright, the company in charge of security at all the airports used by the hijackers, had virtually no security check on any of its employees, and even hired criminals and illegal immigrants. Security appears to be particularly abysmal at Boston’s Logan Airport, even after 9/11. [Boston Globe, 10/1/2001; CNN, 10/12/2001] An FAA official had similar concerns about two other security contractors at Logan Airport: Huntleigh USA, a subsidiary of ICTS International NV, a large Israeli security company, and Globe Aviation.

According to numerous rescue and recovery workers, the area around WTC Building 7 is evacuated at this time. [Kansas City Star, 3/28/2004] For example:
bullet Emergency medical technician Joseph Fortis says, “They pulled us all back at the time, almost about an hour before it, because they were sure—they knew it was going to come down, but they weren’t sure.” [City of New York, 11/9/2001]
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]

Mark Jacobson, a reporter for New York Magazine, later recounts an encounter he has about this time. Walking through the ruins of the World Trade Center complex, he sits down next to a weary and dust covered firefighter. The firefighter points to WTC Building 7, perhaps 400 yards away, and says, “That building is coming down.” Jacobson asks when and the firefighter responds, “Tonight. Maybe tomorrow morning.” Jacobson watches as the building collapses about five minutes later. [New York Magazine, 3/20/2006]

[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]

Attorney General John Ashcroft briefs about 250 members of Congress on the latest developments regarding the day’s terrorist attacks. [Associated Press, 9/12/2001] Since he arrived there in the early afternoon (see (Between 1:00 p.m. and 2:00 p.m.) September 11, 2001), Ashcroft has spent most of the day at the Strategic Information and Operations Center at the FBI’s headquarters in Washington, DC (see (2:00 p.m.-8:30 p.m.) September 11, 2001). He and other senior Justice Department officials have repeatedly heard from members of Congress who want more information about the attacks. Ashcroft will later recall, “We tried our best to provide it, but we were still in the heat of battle.” However, “No matter; Congress wanted answers.” Therefore, after attending a meeting at the White House—presumably President Bush’s meeting with his National Security Council and/or his subsequent meeting with his most senior principal national security advisers (see (9:00 p.m.-10:00 p.m.) September 11, 2001)—Ashcroft heads to the police station north of the Hart Senate Office Building, to brief the House and Senate members who are gathered there. [9/11 Commission, 12/17/2003 pdf file; Ashcroft, 2006, pp. 129] About 250 members of Congress are at the briefing. [Associated Press, 9/12/2001] Ashcroft will recall, “The place was jammed with members of Congress, all shouting questions, some complaining about apparent inconsistencies, many expressing dissatisfaction that we didn’t know everything, and all wanting answers that I didn’t know or couldn’t say.” [Ashcroft, 2006, pp. 129] He reportedly tells those at the briefing that “the US government now believes teams of three to five individuals carrying knives commandeered those four airliners earlier today, destroying them and themselves in the process.” [CNN, 9/11/2001; CNN, 9/12/2001] Ashcroft stays at the police station until well after midnight, holding what he will describe as “an intense discussion” with the members of Congress. He has to say “I don’t know” over and over again, he will recall. [Ashcroft, 2006, pp. 129]

Susan Mcelwain, who lives two miles from the Flight 93 crash site, had seen a small jet plane flying very low overhead as she was driving home. She later recalls that it had been “heading right to the point where Flight 93 crashed and must have been there at the very moment it came down.” But it was only later in the afternoon, after returning home and turning on the TV, that she’d realized what she’d seen was connected to the attacks in New York and Washington. While she was confused that a Boeing 757—not a small jet plane—was being reported as having gone down near where she’d been, she’d then realized that the small plane was flying in a different direction to that being described for Flight 93. So she got her husband to tell the police about what she’d witnessed. Consequently, late in the evening, the FBI turns up to talk to her about it. Yet, as Mcelwain later recalls, “They did not want my story.” They keep asking her how big the plane she’d seen was. When she tells them it was small, not much bigger than her van, one of the agents tells her, “You don’t know what a 757 looks like.” She retorts, “Don’t be condescending towards me. If you don’t want to believe me, that’s fine, but I thought I should report what I saw. You ought to know there was something else in the air at the same time this was going on. We want to make sure it was ours and not somebody else’s.” After this, she will recall, the agent “did seem to get a little nicer. Told me that it was a white Learjet. Somebody was taking pictures. And I said, ‘Before the crash?’ and he says, ‘Well, we’ve got to go,’ and that was the end of it.” [Bergen Record, 9/14/2001; Mirror, 9/12/2002; Lappe and Marshall, 2004, pp. 38-40] Numerous other witnesses also saw a small jet plane flying above the crash site around the time Flight 93 reportedly went down (see (Before and After 10:06 a.m.) September 11, 2001).

It was found in a trash compactor at the Days Inn, near the Newark Airport. [Source: FBI]Investigators find a remarkable number of possessions left behind by the hijackers:
bullet Two of Mohamed Atta’s bags are found on 9/11. They contain a handheld electronic flight computer, a simulator procedures manual for Boeing 757 and 767 aircraft, two videotapes relating to “air tours” of the Boeing 757 and 747 aircraft, a slide-rule flight calculator, a copy of the Koran, Atta’s passport, his will, his international driver’s license, a religious cassette tape, airline uniforms, a letter of recommendation, “education related documentation” and a note (see September 28, 2001) to other hijackers on how to mentally prepare for the hijacking. [Sydney Morning Herald, 9/15/2001; Boston Globe, 9/18/2001; Independent, 9/29/2001; Associated Press, 10/5/2001] Author Terry McDermott will later comment, “Atta’s bag contained nearly every important document in his life… If you wanted to leave a roadmap for investigators to follow, the suitcase was a pretty good place to start.” [McDermott, 2005, pp. 306]
bullet Marwan Alshehhi’s rental car is discovered at Boston’s Logan Airport containing an Arabic language flight manual, a pass giving access to restricted areas at the airport, documents containing a name on the passenger list of one of the flights, and the names of other suspects. The name of the flight school where Atta and Alshehhi studied, Huffman Aviation, is also found in the car. [Los Angeles Times, 9/13/2001]
bullet A car registered to Nawaf Alhazmi is found at Washington’s Dulles Airport on September 12. This is the same car he bought in San Diego in early 2000 (see March 25, 2000). Inside is a copy of Atta’s letter to the other hijackers, a cashier’s check made out to a flight school in Phoenix, four drawings of the cockpit of a 757 jet, a box cutter-type knife, maps of Washington and New York, and a page with notes and phone numbers. [Arizona Daily Star, 9/28/2001; Cox News Service, 10/21/2001; Die Zeit (Hamburg), 10/1/2002] The name and phone number of Osama Awadallah, a friend of Alhazmi and Khalid Almihdhar in San Diego, is also found on a scrap of paper in the car (see September 12, 2001 and After). [CNN, 2/1/2002]
bullet A rental car is found in an airport parking lot in Portland, Maine. Investigators are able to collect fingerprints and hair samples for DNA analysis. [Portland Press Herald, 10/14/2001]
bullet A Boston hotel room contains airplane and train schedules. [Sydney Morning Herald, 9/15/2001]

bullet Two days before 9/11, a hotel owner in Deerfield Beach, Florida, finds a box cutter left in a hotel room used by Marwan Alshehhi and two unidentified men. The owner checks the nearby trash and finds a duffel bag containing Boeing 757 manuals, three illustrated martial arts books, an 8-inch stack of East Coast flight maps, a three-ring binder full of handwritten notes, an English-German dictionary, an airplane fuel tester, and a protractor. The FBI seizes all the items when they are notified on September 12 (except the binder of notes, which the owner apparently threw away). [Miami Herald, 9/16/2001; Associated Press, 9/16/2001]
bullet In an apartment rented by Ziad Jarrah and Ahmed Alhaznawi, the FBI finds a notebook, videotape, and photocopies of their passports. [Miami Herald, 9/15/2001]
bullet In a bar the night before 9/11, after making predictions of a attack on America the next day, the hijackers leave a business card and a copy of the Koran at the bar. The FBI also recovers the credit card receipts from when they paid for their drinks and lap dances. [Associated Press, 9/14/2001]
bullet A September 13 security sweep of Boston airport’s parking garage uncovers items left behind by the hijackers: a box cutter, a pamphlet written in Arabic, and a credit card. [Washington Post, 9/16/2001]
bullet A few hours after the attacks, suicide notes that some of the hijackers wrote to their parents are found in New York. Credit card receipts showing that some of the hijackers paid for flight training in the US are also found. [Los Angeles Times, 9/13/2001]
bullet A FedEx bill is found in a trash can at the Comfort Inn in Portland, Maine, where Atta stayed the night before 9/11. The bill leads to Dubai, United Arab Emirates, allowing investigators to determine much of the funding for 9/11. [Newsweek, 11/11/2001; London Times, 12/1/2001]
bullet A bag hijackers Alhazmi and Almihdhar left at a mosque in Laurel, Maryland, is found on September 12. The bag contains flight logs and even receipts from flight schools from San Diego the year before (see September 9, 2001).
bullet On 9/11, in a Days Inn hotel room in Newark, New Jersey, investigators find used plane tickets for Saeed Alghamdi, Ahmed Alhaznawi, Ziad Jarrah, and Ahmed Alnami. The tickets are all from a Spirit Continental Airlines flight from Ft. Lauderdale, Florida, to Newark on September 7. Also, flight manuals for Boeing 757 and 767 airplanes are found in English and Arabic. [Investigative Services Division, FBI Headquarters, 4/19/2002]
The hijackers past whereabouts can even be tracked by their pizza purchases. An expert points out: “Most people pay cash for pizza. These [hijackers] paid with a credit card. That was an odd thing.” [San Diego Union-Tribune, 9/3/2002] “In the end, they left a curiously obvious trail—from martial arts manuals, maps, a Koran, Internet and credit card fingerprints. Maybe they were sloppy, maybe they did not care, maybe it was a gesture of contempt of a culture they considered weak and corrupt.” [Miami Herald, 9/22/2001] The New Yorker quotes a former high-level intelligence official as saying: “Whatever trail was left was left deliberately—for the FBI to chase” (see Late September 2001).

Michael Burton.Michael Burton. [Source: PBS]Following the World Trade Center collapses, a decision is made to quickly transport the remaining structural steel to scrap yards, to be shipped abroad and melted down for reuse. Consequently, virtually all of it is disposed of before investigators trying to assess why the WTC collapsed can examine it. Michael Burton and other officials at the Department of Design and Construction—the New York City agency overseeing the cleanup operation (see (September 11, 2001-May 2002))—are responsible for making this decision. Burton clears it with Richard Tomasetti of Thornton-Tomasetti Engineers, the prime consultant on the cleanup job. However, referring to the subsequent WTC investigation by the National Institute of Standards and Technology (see August 21, 2002), Tomasetti will later admit that had he known the direction that investigations into the collapses would take, he would have taken a different stand. [Langewiesche, 2002, pp. 30; Glanz and Lipton, 2004, pp. 330 and 396] Authors and New York Times reporters James Glanz and Eric Lipton write that Michael Burton, “who had become the effective czar for the cleanup job, had made it clear that he cared very little about engineering subtleties like the question of why the towers first stood, then collapsed on September 11. ‘We know why they fell,’ he said. ‘Because they flew two planes into the towers.’ But he was deeply immersed in the details of hauling steel out of the debris pile.” [Glanz and Lipton, 2004, pp. 299] Much of the WTC steel will be shipped to India, China, and other Asian countries for recycling (see September 12-October 2001).

It is later reported that FBI officials believe that a second grouping or cell of “perhaps 20 al-Qaeda terrorists [are] in the United States on Sept. 11 to carry out another attack. Members of this second cell, one official [says], apparently [abandon] apartments they… rented in Paterson, New Jersey, and Fairfax, Virginia, just outside Washington, D.C., after Sept. 11, leaving rented furniture and other possessions behind in their haste.” [St. Paul Pioneer Press, 10/7/2002] Another article notes, “Police always have had concerns about sleeper agents in the [Brooklyn, New York] area. They particularly were concerned by a story… from several NYPD sources about an abandoned rental car that was parked in front of a mosque only a few blocks from New Utrecht. The car had been rented under the phony name ‘Bomkr’ from Logan International Airport in Boston shortly before the attacks. Investigators thought the name sounded a lot like ‘bomb car.’ The anonymous party rented several other cars from Logan, all of which either have disappeared or been abandoned. Police suspect the cars were used by al-Qaeda operatives to return to their home bases after the attacks.” [Insight, 9/10/2002]

Mike McCormick.Mike McCormick. [Source: CNN]Managers at the FAA’s New York Center fail to inform their higher-ups of an audio tape that was made on September 11, on which several air traffic controllers recalled their experiences with two of the hijacked aircraft. [New York Times, 5/6/2004; Washington Post, 5/6/2004] New York Center manager Mike McCormick had directed Kevin Delaney, the quality assurance manager, to record statements from the six controllers at the center that had been involved in handling or tracking Flights 11 and 175 (see 11:40 a.m. September 11, 2001). [9/11 Commission, 10/1/2003 pdf file; US Department of Transportation, 5/4/2004 pdf file; Air Safety Week, 5/17/2004]
FAA Superiors Not Informed - However, neither of the two managers subsequently notifies authorities at the FAA’s regional office or Washington headquarters of the existence of the tape with the recorded statements on. Among others, Delaney and McCormick fail to notify the air traffic evaluations and investigations staff at headquarters, which is the FAA’s policy authority on aircraft accident and incident investigations. They also fail to inform FAA authorities of agreements they made with the National Air Traffic Controllers Association to destroy the tape at a future date (see (Shortly Before 11:40 a.m.) September 11, 2001 and October 2001-February 2002). Additionally, they do not inform the FBI of the tape’s existence (see September 12, 2001).
Investigations Staff Could Have Prevented Tape's Destruction - Delaney deliberately destroys the tape of the controllers’ statements at some point between December 2001 and February 2002 (see Between December 2001 and February 2002). But had he or McCormick consulted with the FAA’s air traffic evaluations and investigations staff, they would have been “instructed that the tape—as an original record—be retained, for five years, in accordance with agency retention requirements,” according to a 2004 report by the Department of Transportation’s Office of Inspector General (see May 6, 2004).
Tape Learned of in Late 2003 - This report will also state, “When we interviewed officials from outside of New York Center, including the then-FAA administrator, deputy administrator, and director of air traffic services, they told us they were unaware that controller statements had been taped until the issue arose following the 9/11 Commission interviews of center personnel in September and October 2003.” [US Department of Transportation, 5/4/2004 pdf file]

The Royal Canadian Mounted Police (RCMP) in Whitehorse, Yukon Territory, Canada, finally confirms that a suspicious passenger jet that landed at Whitehorse Airport the previous afternoon was never hijacked. [Yukon Government, 11/13/2001, pp. 18 pdf file; Alaska Legislature. Joint Senate and House Armed Services Committee, 2/5/2002]
Plane Showed Five Indicators of a Hijacking - Korean Airlines Flight 85 is a Boeing 747 that was heading from Seoul, South Korea, to New York on September 11, but was diverted to Whitehorse (see (Shortly After 1:24 p.m.) September 11, 2001). Although the plane was not hijacked, its pilots had been giving indications that it was hijacked (see (Shortly Before 12:00 p.m.) September 11, 2001 and 1:24 p.m. September 11, 2001). [USA Today, 8/12/2002; Spencer, 2008, pp. 277-278] According to a report published by the government of Yukon, “There were five separate and ongoing indicators of a hijacking situation,” although the report will not specify what those indicators were. [Yukon Government, 11/13/2001, pp. 17 pdf file]
Pilots and Crew Questioned - Flight 85 landed at Whitehorse Airport without incident at 2:54 p.m. the previous afternoon (see 2:54 p.m. September 11, 2001). [USA Today, 8/12/2002; Anchorage Daily News, 9/8/2002] Investigators then interviewed its pilots and crew. [Anchorage Daily News, 9/29/2001; Spencer, 2008, pp. 278-279] One of the pilots cited miscommunication as the reason for the false hijack reports. [Yukon Government, 11/13/2001, pp. 17, 36 pdf file]
Spokeswoman Announced No Hijacking - Several hours after Flight 85 landed, airport spokeswoman Brenda Wale had announced: “It’s not a hijacking situation. There was a communications problem aboard the plane so they were unable to communicate and respond properly to the tower anywhere they went. It raised alarm bells.” [Canadian Press, 9/12/2001] At 5:10 p.m. that afternoon, following a discussion between the RCMP and other responding agencies, Whitehorse Airport and part of the Alaska Highway that had been closed earlier on were reopened.
Police Confirms No Hijacking of Flight 85 - Because hijacking is a criminal activity, the Whitehorse RCMP has been in charge of the local response to Flight 85. Very early this morning, it brings a bomb-sniffing dog onto the plane to search it. The aircraft’s cargo is also searched. No threats are found. Finally, two hours later, the RCMP confirms that a hijacking situation did not exist on Flight 85. The aircraft is security cleared and approved to depart from Whitehouse once FAA and Transport Canada airspace restrictions have been lifted and scheduling requirements have been made. [Yukon Government, 11/13/2001, pp. 4, 14-18 pdf file] Flight 85 will leave Whitehorse on September 13, and fly on to New York. [Anchorage Daily News, 9/29/2001; Anchorage Daily News, 9/8/2002]

Dr. Marcella FierroDr. Marcella Fierro [Source: Ernie Branson]Virginia Chief Medical Examiner Dr. Marcella Fierro, believing that state forensic pathologists have jurisdiction over the Pentagon’s land, reassigns staff from three other regional offices to the Northern Virginia office in order to conduct postmortem examinations on victims of the Pentagon attack. However, following what the Washington Post calls a “behind-the-scenes tug of war,” after FBI and Defense Department officials meet with her they instead opt to conduct forensic and mortuary activities at Defense Department facilities. Fierro requests and later receives a letter from Attorney General John Ashcroft relieving her department of its responsibilities.

The Saudi passport of Saeed Alghamdi, said to be discovered in the wreckage of Flight 93.The Saudi passport of Saeed Alghamdi, said to be discovered in the wreckage of Flight 93. [Source: FBI]According to the 9/11 Commission, the passports of two hijackers are discovered in the wreckage of Flight 93. One passport, belonging to Saeed Alghamdi, is damaged but still readable. The other passport, belonging to Ziad Jarrah, is burned most of the way through, but part of his photograph is still visible. In addition, the passport of hijacker Abdulaziz Alomari is recovered because apparently it was put in Mohamed Atta’s luggage and the luggage did not get put on the flight Alomari and Atta were hijacking before it took off (see September 11-13, 2001). The recovery of these passports will not be made public at the time and will only be mentioned in passing in 2004 by the 9/11 Commission. A fourth passport, that of Satam Al Suqami, was also recovered on a street near the WTC (see After 8:46 a.m. September 11, 2001). That did become immediate news and caused skepticism by many who wondered how a paper document could survive such a crash (see After 8:46 a.m. September 11, 2001). [9/11 Commission, 1/26/2004]

After arriving at FAA headquarters on September 12, Tony Ferrante, the manager of FAA investigations, spends several days working out the movements of the four hijacked planes. He is astonished at the precision with which they were flown towards their targets, later saying: “[I]t was almost as though it was choreographed.… It’s not as easy as it looks to do what they did at 500 miles an hour.” He concludes that either the hijackers were better pilots than originally thought, or they were aided by additional equipment such as radios to communicate among the four planes or handheld Global Positioning System (GPS) equipment. [Freni, 2003, pp. 74 and 76] 9/11 Commission investigators will in fact later speculate that the hijackers may have purchased GPS devices, “so they could determine the latitude and longitude of their intended targets.” According to a summary of a Commission interview, “Any autopilot changes made by the terrorist pilots to assist them in navigating to predetermined coordinates would simply have been to enter a specific location such as Newark or Reagan National” Airport. However, airline personnel will tell the 9/11 Commission investigators that “Entering changes to the autopilot is something that terrorist pilots probably would not have been trained or able to do.” Even a United Airlines senior pilot, who instructs on how to do this, says “he always has to pause before he makes such corrections to make sure to remember how to enter the change.” [9/11 Commission, 11/17/2003 pdf file]

Billie Vincent, a former FAA security director, suggests the hijackers had inside help at the airports. “These people had to have the means to take control of the aircrafts. And that means they had to have weapons in order for those pilots to relinquish control. Think about it, they planned this thing out to the last detail for months. They are not going to take any risks at the front end. They knew they were going to be successful before they started… It’s the only thing that really makes sense to me.” [Miami Herald, 9/12/2001] The same day, the Boston Globe reports, “A former TWA official said he knew of at least two cases in which members of a cleaning crew smuggled weapons on board which were later used to hijack planes.… One source familiar with the airline industry said that, given enough time and money, it would not be difficult for terrorists to smuggle weapons onto a domestic flight. He said terrorists could arrange to have weapons moved onto an airliner by having terrorists or sympathizers hired as air cargo handlers or airline cleaners. The weapons could then be brought on board and concealed without ever having to pass through a security checkpoint. ‘If you have a year or more to plan, how hard can it be to get someone hired to clean the trash out of an airplane,’ the source said.” [Boston Globe, 9/12/2001]

W. Gene Corley.W. Gene Corley. [Source: ASCE]The Federal Emergency Management Agency (FEMA) and its contractor, Greenhorne and O’Mara, Inc., from Greenbelt, Maryland, begin putting together a Building Performance Assessment Team (BPAT), to conduct a formal analysis of the World Trade Center collapses, and produce a report of its findings. FEMA routinely deploys such teams following disasters, like floods or hurricanes. The 23-member BPAT team set up at the WTC collapse site is assembled by the American Society of Civil Engineers (ASCE), and headed by Dr. W. Gene Corley of Construction Technologies Laboratories in Skokie, Illinois. Corley was previously the principal investigator for FEMA’s study of the Murrah Building, in Oklahoma City in 1995. [New Yorker, 11/12/2001] BPAT team members are based nationwide and have to communicate with each other mostly by phone, as they continue with their regular jobs. While some of them are being paid for their efforts, others are working on the investigation voluntarily. They are told not to speak with reporters, under threat of dismissal from the team, supposedly because of the delicacy of the subject with which they are dealing. The BPAT team receives $600,000 of funding from FEMA, plus approximately $500,000 in ASCE in-kind contributions. [New York Times, 12/25/2001; Associated Press, 1/14/2002; US Congress, 3/6/2002] The team will have great difficulty accessing the collapse site and evidence they want to see (see March 6, 2002). They will be unable to get FEMA to obtain such basic data as detailed blueprints of the WTC buildings. FEMA will also refuse to allow them to make appeals to the public for photos and videos of the towers that might aid their investigation. Bureaucratic restrictions will often prevent them from making forensic inspections at Ground Zero, interviewing witnesses, or getting important evidence, like recorded distress calls from people who were trapped in the towers. [Glanz and Lipton, 2004, pp. 330] The end product of their investigation is the FEMA World Trade Center Building Performance Study, released in May 2002 (see May 1, 2002).

White House Press Secretary Ari Fleischer explains that President Bush went to Nebraska because “[t]here was real and credible information that the White House and Air Force One were targets.” The next day, William Safire of the New York Times writes, and Bush’s political strategist, Karl Rove, confirms, that the Secret Service believed “‘Air Force One may be next,’ and there was an ‘inside’ threat which ‘may have broken the secret codes [i.e., showing a knowledge of presidential procedures].’” [New York Times, 9/13/2001] By September 27, Fleischer begins to backpedal on the claim that there were specific threats against Air Force One and/or the president, and news stories flatly contradict it. [Washington Post, 9/27/2001] A well-informed, anonymous Washington official says, “It did two things for [Cheney]. It reinforced his argument that the president should stay out of town, and it gave George W. an excellent reason for doing so.” [Daily Telegraph, 12/16/2001] By 2004, a Bush spokesperson says there was no threat, but Cheney continues to maintain that there may have been. Cheney also claims the Secret Service passed him word of the threat, but two Secret Service agents working that day deny their agency played any role in receiving or passing on such a threat. The threat was allegedly based on the use of the word “Angel,” the code word for Air Force One, but Secret Service agents later note that the code word was not an official secret, but a radio shorthand designation that had been made public well before 2001.

Despite having been told by the FBI not to do so, Deena Burnett decides to speak to several groups of reporters about the four calls her husband Tom Burnett made to her from Flight 93, before it crashed in Pennsylvania. The FBI visited Deena the previous evening and, she later recalls, “told me specifically not to say anything to anyone about my cell phone conversations with Tom, especially the media, because it was part of their investigation.” [Burnett and Giombetti, 2006, pp. 81] But by this morning, she will comment, “everything I would have told the media had been reported on the news by the FBI, police, and Father Frank” Colacicco, from the church where her family worships. “If they could tell their stories, I knew now I could tell mine. There would be no harm to ‘the evidence’ in answering [reporters’] questions.” [San Francisco Chronicle, 9/12/2001; Burnett and Giombetti, 2006, pp. 93-94] Throughout the day, she has six “media waves” separately come into her home to interview her. The reporters are interested in the cell phone calls she received from her husband. She recalls: “I had to be very cautious about everything I said. I didn’t want to say anything that would interfere with the FBI investigation. I verified the calls had taken place, but gave no specific information about what Tom and I had discussed.” The FBI visits Deena around 3:00 p.m. to ask some follow-up questions to their interviews with her the previous day (see (12:30 p.m.) September 11, 2001). In her 2006 book, Deena Burnett makes no mention of them complaining about her having talked to the media. [Burnett and Giombetti, 2006, pp. 97-104]
