Peter Caram.Peter Caram. [Source: SRR Training]The New York Port Authority, which owns the World Trade Center, is aware of terrorism occurring around the world and that the WTC is vulnerable to attack. It has therefore created the Terrorist Intelligence Unit within its police department, headed by Detective Sergeant Peter Caram, to gather information about terrorist groups and assess the vulnerability of its numerous facilities to attack. On this day, Caram writes a memo to the assistant superintendent of the Port Authority Police Department, reporting that the FBI has uncovered a terrorist threat: Two supporters of Ayatollah Khomeini are allegedly planning to bomb the WTC in the near future. Although the attack never occurs, this is the first of numerous occasions during the 1980s where the WTC is considered a potential target for a terrorist attack.

Detective Sergeant Peter Caram, the head of the New York Port Authority’s Terrorist Intelligence Unit, has been directed by the assistant superintendent of the Port Authority Police Department to compile a report on the vulnerability of the WTC to a terrorist attack. Having previously worked at the WTC Command, Caram has exclusive knowledge of some of the center’s security weaknesses. On this day he issues his four-page report, titled “Terrorist Threat and Targeting Assessment: World Trade Center.” It looks at the reasoning behind why the WTC might be singled out for attack, and identifies three areas of particular vulnerability: the perimeter of the WTC complex, the truck dock entrance, and the subgrade area (the lower floors below ground level). Caram specifically mentions that terrorists could use a car bomb in the subgrade area—a situation similar to what occurs in the 1993 bombing (see February 26, 1993). [Caram, 2001, pp. 5, 84-85; New York County Supreme Court, 1/20/2004] This is the first of several reports during the 1980s, identifying the WTC as a potential terrorist target.

Peter Goldmark.Peter Goldmark. [Source: Environmental Defense Fund]Peter Goldmark, the executive director of the New York Port Authority, is concerned that, in light of terrorist attacks occurring around the world (see April 18-October 23, 1983), Port Authority facilities, including the World Trade Center, could become terrorist targets. [Associated Press, 9/28/2005; New York Times, 10/27/2005] He therefore creates a unit called the Office of Special Planning (OSP) to evaluate the vulnerabilities of all Port Authority facilities and present recommendations to minimize the risks of attack. The OSP is staffed by Port Authority police and civilian workers, and is headed by Edward O’Sullivan, who has experience in counterterrorism from earlier careers in the Navy and Marine Corps. In carrying out its work, the OSP will consult with such US agencies as the FBI, CIA, Secret Service, NSA, and Defense Department. It will also consult with security officials from other countries that have gained expertise in combating terrorism, such as England, France, Italy, and Israel. [Glanz and Lipton, 2004, pp. 226; New York County Supreme Court, 1/20/2004] According to Peter Caram, head of the Port Authority’s Terrorist Intelligence Unit, the OSP will develop “an expertise unmatched in the United States.” [Caram, 2001, pp. 12] In 1985 it will issue a report called “Counter-Terrorism Perspectives: The World Trade Center” (see November 1985). [New York Court of Appeals, 2/16/1999] It will exist until 1987. [Village Voice, 1/5/2000]

The Office of Special Planning (OSP), a unit set up by the New York Port Authority to assess the security of its facilities against terrorist attacks (see Early 1984), spends four to six months studying the World Trade Center. It examines the center’s design through looking at photographs, blueprints, and plans. It brings in experts such as the builders of the center, plus experts in sabotage and explosives, and has them walk through the WTC to identify any areas of vulnerability. According to New York Times reporters James Glanz and Eric Lipton, when Edward O’Sullivan, head of the OSP, looks at WTC security, he finds “one vulnerability after another. Explosive charges could be placed at key locations in the power system. Chemical or biological agents could be dropped into the coolant system. The Hudson River water intake could be blown up. Someone might even try to infiltrate the large and vulnerable subterranean realms of the World Trade Center site.” In particular, “There was no control at all over access to the underground, two-thousand-car parking garage.” However, O’Sullivan consults “one of the trade center’s original structural engineers, Les Robertson, on whether the towers would collapse because of a bomb or a collision with a slow-moving airplane.” He is told there is “little likelihood of a collapse no matter how the building was attacked.” [Glanz and Lipton, 2004, pp. 227; New York County Supreme Court, 1/20/2004] The OSP will issue its report called “Counter-Terrorism Perspectives: The World Trade Center” late in 1985 (see November 1985).

Charles Schnabolk.Charles Schnabolk. [Source: Institute for Design Professionals]While the Office of Special Planning is still working on its report about the vulnerability of the World Trade Center to terrorist attack, the New York Port Authority hired security consultant Charles Schnabolk to also review the center’s security systems. [UExpress (.com), 10/12/2001; New York County Supreme Court, 1/20/2004] Schnabolk was involved in designing the original security system when the WTC complex was built. [Institue for Design Professionals, 2009; The Security Design Group, 2010] This month his secret report, titled “Terrorism Threat Perspective and Proposed Response for the World Trade Center” is released. It sets out four levels of possible terrorism against the center, and gives examples of each: ”(1) PREDICTABLE—Bomb threats; (2) PROBABLE—Bombing attempts, computer crime; (3) POSSIBLE—Hostage taking; (4) CATASTROPHIC—Aerial bombing, chemical agents in water supply or air conditioning (caused by agents of a foreign government or a programmed suicide).” Similar to other reports in the mid-1980s, it also warns that the WTC “is highly vulnerable through the parking lot.” [UExpress (.com), 10/12/2001; New York County Supreme Court, 1/20/2004]

After assessing the security of New York Port Authority facilities, the Office of Special Planning (OSP), the Port Authority’s own antiterrorist task force, releases a report called “Counter-Terrorism Perspectives: The World Trade Center.” For security purposes, only seven copies are made, being hand-delivered and signed for by its various recipients, including the executive director of the Port Authority, the superintendent of the Port Authority Police, and the director of the World Trade Department. [New York Court of Appeals, 2/16/1999; Village Voice, 1/5/2000] Because of the WTC’s visibility, symbolic value, and it being immediately recognizable to people from around the world, the report concludes that the center is a “most attractive terrorist target.” [New York County Supreme Court, 1/20/2004] The report, which is 120 pages long, lists various possible methods of attacking the center. [New York Court of Appeals, 2/16/1999; Caram, 2001, pp. 103; Barrett and Collins, 2006, pp. 87] One of these is that a “time bomb-laden vehicle could be driven into the WTC and parked in the public parking area.… At a predetermined time, the bomb could be exploded in the basement.” [Glanz and Lipton, 2004, pp. 227] As a Senate Committee Report will find in August 1993, “The specifics of the February 26, 1993 bombing at the World Trade Center garage were almost identical to those envisioned in the [OSP] report.” [New York Court of Appeals, 2/16/1999] Due to the Port Authority’s failure to adequately implement the OSP’s recommendations, the report will be crucial evidence in a successful civil trial against it in October 2005, charging negligence in failing to prevent the 1993 bombing. [Bloomberg, 10/26/2005; New York Times, 10/27/2005; New York Times, 2/18/2006] As of mid-2006, the other possible methods of attacking the WTC listed in the report remain undisclosed.

Following the release of the Office of Special Planning’s (OSP) report, which called the WTC a “most attractive terrorist target” (see November 1985), the New York Port Authority, which owns the center, seeks a second opinion on the OSP’s recommendations. At a cost of approximately $100,000, it hires the Science Applications International Corporation (SAIC) to review the general security of the WTC. SAIC states in its report that the attractiveness of the WTC’s public areas to terrorists is “very high.” Like the OSP, SAIC pays particular attention to the underground levels of the center and describes a possible attack scenario much like what occurs in the 1993 bombing.

The New York Port Authority’s Office of Special Planning (OSP) is closed down. It had been established in 1984 (see Early 1984) to evaluate and address the vulnerabilities of Port Authority facilities, including the World Trade Center, to terrorist attacks. [Village Voice, 1/5/2000; New York County Supreme Court, 1/20/2004] The reasons for the closure are unknown. However, Peter Goldmark, who’d created the OSP, had resigned as executive director of the Port Authority in 1985 to take a new job. [Glanz and Lipton, 2004, pp. 226-228] So the absence of his support for the office may have been a factor.

Rick Rescorla, a security chief for a company at the World Trade Center, and Dan Hill, a former Army colleague of his, write a report in which they warn that terrorists could attack the WTC by detonating a truck filled with explosives in the underground parking garage, but the Port Authority, which manages the WTC, dismisses their warning. Rescorla, who previously served in the US Army, is now working as the director of security at brokerage firm Dean Witter, and his office is on the 44th floor of the WTC’s South Tower. [Stewart, 2002, pp. 173-177; New Yorker, 2/11/2002]
Former Army Ranger Agrees to Identify WTC Vulnerabilities - Rescorla has become increasingly concerned about the possibility of a terrorist attack in the United States, especially after Pan Am Flight 103 was blown up by a terrorist bomb over Scotland in December 1988, and he thinks the WTC is “an obvious target.” He therefore asks his friend Hill to join him in New York and be his consultant. [Stewart, 2002, pp. 173] Hill, a former Army Ranger, has been trained in counterterrorism, unconventional warfare, demolition, and the use of explosives. [Stewart, 2002, pp. 152-153] “If anyone can figure out how to hurt this building, you can,” Rescorla tells him, and adds, “I want to know the worst.” Hill agrees to help Rescorla. After he arrives in New York, Rescorla takes him to the WTC. Rescorla explains the basic engineering of the Twin Towers and suggests they examine the buildings, starting at the bottom and then working up.
Parking Area Has No Visible Security - The two men begin by walking around the entire 16-acre WTC complex. Hill then asks Rescorla where the loading and docking operations are, and Rescorla takes him to a ramp that goes to the basement levels of the WTC. After they walk down the ramp, past a loading dock, and into a parking area, Hill asks, “Where are the guards?” Rescorla replies, “There are no guards.” Hill then notices that all the major columns and supporting beams in the parking area are visible and exposed.
Hill Thinks Parking Area Is a 'Soft Touch' - After thinking for a few minutes, Hill says: “Hell, Rick. This is a soft touch. It’s not even a challenge.” He then explains to Rescorla how he would attack the WTC if he was a terrorist. According to journalist and author James B. Stewart, Hill says he would “bring in a stolen truck, painted like a delivery truck. He’d fill it with a mixture of ammonium nitrate and diesel fuel, then drive down the ramp and park. With four or five men dressed in coveralls, he could plant additional charges near key supporting pillars within 15 minutes. Then he and the men would walk out and disperse, and he’d remove his coveralls.” He would then take a taxi to another location, where he would have a van waiting with a woman, two children, and possibly a dog inside. He would use a cell phone or a beeper to detonate the truck bomb and then make his getaway. “Nobody’s going to stop a family and a dog on Interstate 95,” Hill tells Rescorla.
Port Authority Dismisses Rescorla's Concerns - Later on, the two men analyze Hill’s findings and incorporate them into a report for the Port Authority of New York and New Jersey, which manages the WTC buildings. The following day, Rescorla meets with some Port Authority officials and notifies them of his and Hill’s concerns, but they are uninterested. Rescorla later tells Hill that the officials’ response was to say, “You worry about your floors and we’ll worry about the rest, including the basements and parking.” All the same, Rescorla sends copies of his and Hill’s report to the Port Authority and also the New York City Police Department, but he receives no responses. Rescorla and Hill are unaware that the Port Authority’s Office of Special Planning submitted a report in 1985 that warned of a bombing at the WTC of a similar kind to what they have envisioned, and also emphasized the vulnerability of the basement levels (see November 1985). However, no steps were taken to increase security at the WTC in response to that report. [Stewart, 2002, pp. 173-177] In February 1993, terrorists will attack the WTC in almost exactly the way that Hill predicts, by parking a van containing a 1,500-pound urea nitrate bomb in the basement and detonating it with a timer (see February 26, 1993).

During the mid-1980s, a series of reports described the vulnerability of the World Trade Center to terrorist attack (see July 1985)(see November 1985)(see (Mid-1986)). Now, because of the increased risk of terrorism against the US due to the Gulf War, the New York Port Authority hires private security company Burns and Roe Securacom to prepare a further report, and tells them that the WTC is a terrorist target. Unlike previous investigators, Burns and Roe Securacom finds that the center’s shopping and pedestrian areas, rather than the underground parking garage, are the most likely targets. [New York County Supreme Court, 1/20/2004; New York Times, 10/27/2005] After separating from Burns and Roe, Securacom (later called Stratesec) will become one of a number of firms involved in providing security at the WTC, right up to the day of 9/11 (see October 1996).

An FBI explosives expert later states that, “If they had found the exact architectural Achilles’ heel or if the bomb had been a little bit bigger, not much more, 500 pounds more, I think it would have brought her down.” Ramzi Yousef, who has close ties to bin Laden, organizes the attempt. [Village Voice, 3/30/1993; US Congress, 2/24/1998] The New York Times later reports on Emad Salem, an undercover agent who will be the key government witness in the trial against Yousef. Salem testifies that the FBI knew about the attack beforehand and told him they would thwart it by substituting a harmless powder for the explosives. However, an FBI supervisor called off this plan, and the bombing was not stopped. [New York Times, 10/28/1993] Other suspects were ineptly investigated before the bombing as early as 1990. Several of the bombers were trained by the CIA to fight in the Afghan war, and the CIA later concludes, in internal documents, that it was “partly culpable” for this bombing (see January 24, 1994). [Independent, 11/1/1998] 9/11 mastermind Khalid Shaikh Mohammed is an uncle of Yousef and also has a role in the WTC bombing (see March 20, 1993).

Rick Rescorla.Rick Rescorla. [Source: Public domain]Rick Rescorla, a security chief for a company at the World Trade Center, and his friend Dan Hill conduct an analysis of the security measures at the WTC and conclude that terrorists will likely attack the Twin Towers again, probably by crashing a plane into them. Rescorla, who has served in the US Army and worked for British military intelligence, is now the director of security at brokerage firm Dean Witter. His office is on the 44th floor of the WTC’s South Tower. [Washington Post, 10/28/2001; Stewart, 2002, pp. 193-194; New Yorker, 2/11/2002] After the WTC is bombed in February 1993 (see February 26, 1993), Rescorla calls Hill to New York to be his security consultant and assess the situation. [Stewart, 2002, pp. 191; Steve Humphries, 9/11/2005] Hill is a former Army Ranger and has had training in counterterrorism. [New Yorker, 2/11/2002; St. Augustine Record, 8/14/2011]
Anti-American Hostility Found at Mosques - Hill and Rescorla suspect that the WTC bombing was committed by Muslims. Rescorla suggests that Hill, who is himself a Muslim and speaks Arabic, try to gather some intelligence. Hill therefore lets his beard grow and visits several mosques in New Jersey. He gets into conversations with people at the mosques, expressing pro-Islamic opinions and taking an anti-American line. According to journalist and author James B. Stewart: “[A]t every other location, Hill was struck by the intense anti-American hostility he encountered. Though these were not his own views, he barely had to mention that he thought American policy toward Israel and the Middle East was misguided, or that Jews wielded too much political power, to unleash a torrent of anti-American, anti-Semitic rhetoric. Many applauded the bombing of the World Trade Center, lamenting that it hadn’t done more damage.” Referring to his experiences at the mosques, Hill tells Rescorla, “We’ve got a problem.” He also believes that, as the symbolic “tower of the Jews,” the WTC is likely to remain a target for terrorists. [Stewart, 2002, pp. 192-193; New Yorker, 2/11/2002]
Rescorla Thinks Terrorists Will Use a Different Method of Attack - Rescorla thinks that since terrorists failed to bring the Twin Towers down with a truck bomb, they may in future try a different method of attack, such as using a small, portable nuclear weapon or flying a plane into the building. He phones his friend Fred McBee and asks him to examine the possibility of an air attack on the WTC. By using a flight simulator on his computer, McBee concludes that such an attack seems “very viable” (see Shortly After February 26, 1993). [Stewart, 2002, pp. 193; Steve Humphries, 9/11/2005]
Report Warns of Another Attack on the WTC - Hill and Rescorla write a report incorporating their findings and analysis. The report warns that the WTC will likely remain a target for anti-American militants. It notes that Muslim terrorists are showing increasing tactical and technological awareness, and that the numerous young Muslims living in the United States constitute a potential “enemy within.” Rescorla states that terrorists will not rest until they have succeeded in bringing down the Twin Towers.
Hill and Rescorla Suggest Terrorists Flying a Plane into the WTC - Rescorla and Hill also lay out what they think the next terrorist attack could look like. According to Stewart, it would involve “an air attack on the Twin Towers, probably a cargo plane traveling from the Middle East or Europe to Kennedy or Newark Airport, loaded with explosives, chemical or biological weapons, or even a small nuclear weapon. Besides New York, other cities might be targeted, such as Washington or Philadelphia. Perhaps terrorists would attack all three.” Rescorla and Hill’s report concludes that Rescorla’s company, Dean Witter, should leave the WTC and move to somewhere safer in New Jersey. However, Dean Witter’s lease does not expire until 2006, and so the company will remain at the WTC. But Rescorla will start conducting regular evacuation drills for all its employees in the South Tower. [Stewart, 2002, pp. 193-194; New Yorker, 2/11/2002] Rescorla will be in his office at the WTC on 9/11. He will personally escort his company’s employees out of the South Tower, but die himself when the tower collapses. [Washington Post, 10/28/2001; BBC, 2/10/2003]

Fred McBee.Fred McBee. [Source: History Channel]Fred McBee, a friend of a security chief for a company at the World Trade Center, determines, using a flight simulator on his computer, that it would be possible for terrorists to crash a jumbo jet into the Twin Towers. [Stewart, 2002, pp. 193; Steve Humphries, 9/11/2005] Rick Rescorla is the director of security at brokerage firm Dean Witter and his office is on the 44th floor of the WTC’s South Tower. In response to the recent bombing at the WTC (see February 26, 1993), he is conducting an analysis of the security measures there. [Washington Post, 10/28/2001; New Yorker, 2/11/2002] Rescorla thinks that terrorists might try attacking the WTC again by crashing a plane into the towers. He therefore phones McBee, who is in Oklahoma, and asks him to examine the possibility of an air attack. McBee has the Microsoft Flight Simulator program on his computer. He has been experimenting on the program with a small Cessna plane, but, while he is on the phone with Rescorla, he changes this to a Boeing 737. He then pulls up the image of Lower Manhattan and is able to simulate a crash into the WTC. “It was a piece of cake,” McBee will later comment. “There’s nothing to stop you… once you’re in the air.” He tries to simulate crashing into the Statue of Liberty and the Empire State Building, and is again successful. But when he tries the same experiment with Washington, DC, as the location, he finds that the White House and the Capitol building are blacked out. McBee concludes that a terrorist attack involving crashing a plane into a building “looks very viable.” Presumably taking McBee’s findings into account, Rescorla co-writes a report in which he states that the WTC is likely to remain a target for terrorists, and suggests that the next attack could involve terrorists crashing a cargo plane into the Twin Towers (see Shortly After February 26, 1993).

Roy Goodman.Roy Goodman. [Source: Frances Roberts / New York Times]Three days of public hearings are held to examine the security and safety aspects of the recent World Trade Center bombing. New York State Senator Roy Goodman (R-Manhattan) presides over the hearings. His committee questions 26 witnesses in what journalists Wayne Barrett and Dan Collins will later call “a no-holds-barred probe of the City [of New York] and of the Port Authority.” [Newsday, 11/12/2001; Barrett and Collins, 2006, pp. 86]
Bombing Was a 'Dire Warning' - During the hearings, Goodman calls the WTC “an extremely inviting target” for terrorists, and says the recent bombing (see February 26, 1993) was a “tragic wake-up call” and “a dire warning of the future disasters which could occur with far greater loss of life if we fail to prepare” for terrorism “here at home.” [Albany Times Union, 10/2/2001; Barrett and Collins, 2006, pp. 86-87] He also refers to a number of Port Authority consultant and internal security reports, which predicted the kind of bombing that occurred at the WTC (see January 17, 1984, July 1985, November 1985, and (Mid-1986)), and criticizes Port Authority officials who appear for failing to follow the recommendations of these reports.
Detective Says He Fears a 'Further Disaster' - One Port Authority employee who appears, Detective Sergeant Peter Caram, warns about the continuing threat to the WTC. Caram is the only Port Authority employee with a top security clearance and who is assigned to the New York Joint Terrorism Task Force. He says he fears a “further disaster somewhere down the line” and, referring to the WTC, implores the Port Authority to “harden our target.” James Fox, the assistant director in charge of the FBI’s New York office, similarly warns, “We would be well advised to prepare for the worst and hope for [the] best.” And New York City Police Commissioner Raymond Kelly says New York should remain at “a heightened state of awareness and readiness for the foreseeable future.” [Barrett and Collins, 2006, pp. 87]
Official Recommends Practicing for a Plane Hitting the WTC - On the final day of the hearings, Guy Tozzoli, the director of the Port Authority’s World Trade Department, recalls a drill held in 1982, which simulated a plane crashing into the WTC (see November 7, 1982), and recommends that New York’s emergency response agencies train again for an aircraft hitting the Twin Towers (see (March 29, 1993)). [Newsday, 11/12/2001]
Report Based on Hearings Is 'Largely Ignored' - The exact dates of the hearings are unclear. The hearings begin on March 22, according to Barrett and Collins. [Barrett and Collins, 2006, pp. 86] And according to Newsday, March 29 is the third and final day of the hearings. [Newsday, 11/12/2001] Goodman will issue a 34-page report in August this year based on the hearings. The report, titled “The World Trade Center Bombing: A Tragic Wake-Up Call,” will describe the WTC as “a singular potential terrorist target.” It will call for a special task force and for increased security in the parking facilities under public skyscrapers. But Goodman will say, shortly after 9/11, that his report’s recommendations “were largely ignored as time dulled the sensitivity of the public to terrorist threats.” [Albany Times Union, 10/2/2001; Newsday, 11/12/2001; Barrett and Collins, 2006, pp. 88]

Friedman, writing for New York magazine, will later report that at this time the CIA “fought with the FBI over arresting Yousef in Pakistan—the CIA reportedly wanted to continue tracking him—and President Clinton was forced to intervene.” [New York Magazine, 3/17/1995] Yousef is rendered to the US the next day and makes a partial confession while flying there (see February 8, 1995).

Shortly after bomber Ramzi Yousef is arrested (see February 7, 1995), investigators discover a computer file of a letter on his laptop that is signed by “Khalid Sheikh, and Bojinka.” An eyewitness account of the arrest is given to Time magazine by a “Khalid Sheikh,” who is also staying in the same building. [McDermott, 2005, pp. 154, 162] Investigators also discover that Khalid Shaikh Mohammed (KSM) had frequently visited Yousef’s apartment in Manila, Philippines, where the bombs for the Bojinka plot were being made. [PBS Frontline, 10/3/2002] They also find Yousef has multiple fax and phone numbers for a “Khalid Doha.” Doha is the capital of Qatar. KSM has been living there openly since 1992 (see 1992-1995). Shortly after being apprehended, US authorities notice that Yousef calls one of these numbers in Qatar and asks to speak to a “Khalid.” The US already connected KSM to the 1993 WTC bombing just weeks after that attack and knew that he was living in Doha, Qatar (see March 20, 1993). [US Congress, 7/24/2003] There is an entry in Yousef’s seized telephone directory for a Zahid Shaikh Mohammed, Yousef’s uncle and KSM’s brother. Not long after this discovery is made, Pakistani investigators raid Zahid’s offices in Peshawar, Pakistan, but Zahid has already fled (see 1988-Spring 1995). In 1993, US investigators already discovered the connections between Yousef, Zahid, and KSM, after raiding Zahid’s house in Pakistan and finding pictures of them (see Spring 1993). [McDermott, 2005, pp. 154, 162] The FBI successfully arranges for a photograph to be taken of KSM. He is positively identified from the photo in December 1995. This results in his indictment in January 1996 for his role in the 1993 WTC bombing. US intelligence labels him a “top priority,” according the 9/11 Congressional Inquiry.

[Source: CBC]In the wake of uncovering the Operation Bojinka plot, Philippine authorities find a letter on a computer disc written by the plotters of the failed 1993 WTC bombing. This letter apparently was never sent, but its contents will be revealed in 1998 congressional testimony. [US Congress, 2/24/1998] The Manila police chief also reports discovering a statement from bin Laden around this time that, although they failed to blow up the WTC in 1993, “on the second attempt they would be successful.” [Agence France-Presse, 9/13/2001]
