George H. W. Bush replaces Ronald Reagan and remains president until January 1993. Many of the key members in his government will have important positions again when his son George W. Bush becomes president in 2001. For instance, Joint Chiefs of Staff Chairman Colin Powell later becomes Secretary of State, and Defense Secretary Dick Cheney later becomes vice president.
May 31, 1989: TV Documentary Warns of the Possibility of Terrorists Crashing a Plane into a Building in Washington
Jack Anderson, a Pulitzer Prize-winning investigative reporter, warns in a television documentary that terrorists could crash a plane into a landmark building in Washington, DC, such as the Pentagon or the White House. Anderson will later write that in the program he points out “the vulnerability of Washington landmarks to a terrorist attack.” The reasoning behind his warning, he will write, is that Reagan National Airport in Washington is “a greater convenience for terrorists hoping to attack the White House, the Capitol, or the Pentagon.” He notes in the documentary that “a plane could appear to onlookers to be landing at Reagan [National Airport], take a turn, and dive at the most critical seats of government.” The documentary is “created 10 years before the attacks on the World Trade Center and the Pentagon,” Anderson will write, which would mean it is made in 1991. [Meridian Magazine, 9/18/2001; Casa Grande Dispatch, 7/28/2004] However, other accounts indicate that the documentary he will describe is in fact a program broadcast in May 1989, titled “Target USA.” This program includes “a chain of revelations of various plans by terrorist groups within and outside of the US,” according to its producer, Saban Productions. In it, Anderson “spells out what he says is a real threat to the American infrastructure,” according to the Chicago Tribune. He interviews numerous people whose lives have been involved with or affected by terrorism. Referring to the program, Anderson has commented that after spending “trillions and trillions of dollars” to protect itself from “a nuclear holocaust that’s unlikely to occur now,” America has ended up “with a threat that we’re unprepared for, that is underfunded and underplanned and understrategized [for].” [Hollywood Reporter, 7/11/1988; Chicago Tribune, 5/30/1989] The documentary attracts a large national audience. [Meridian Magazine, 9/18/2001] It is one of the “unheeded warnings” before 9/11 “about terrorists flying airliners into buildings,” Anderson will comment. [Casa Grande Dispatch, 7/28/2004]
1980s and 1990s: Most 9/11 Hijackers Have Middle-Class Backgrounds
Most of the future 9/11 hijackers are middle class and have relatively comfortable upbringings, even though, after 9/11, some people in Western countries will say one of the root causes of the attacks was poverty and assume that the hijackers must have been poor. The editor of Al Watan, a Saudi Arabian daily, will call the hijackers “middle class adventurers” rather than Islamist fundamentalist ideologues. [Boston Globe, 3/3/2002]

1990-2001: NORAD Regularly Launches Fighters to Intercept Suspicious Aircraft before 9/11
Fighter jets are regularly scrambled by the North American Aerospace Defense Command (NORAD) in response to suspicious or unidentified aircraft flying in US airspace in the years preceding 9/11. [General Accounting Office, 5/3/1994, pp. 4; Associated Press, 8/14/2002] For this task, NORAD keeps a pair of fighters on “alert” at a number of sites around the US. These fighters are armed, fueled, and ready to take off within minutes of receiving a scramble order (see Before September 11, 2001). [American Defender, 4/1998; Air Force Magazine, 2/2002; Bergen Record, 12/5/2003; Grant, 2004, pp. 14] Various accounts offer statistics about the number of times fighters are scrambled: A General Accounting Office report published in May 1994 states that “during the past four years, NORAD’s alert fighters took off to intercept aircraft (referred to as scrambled) 1,518 times, or an average of 15 times per site per year.” Of these incidents, the number of scrambles that are in response to suspected drug smuggling aircraft averages “one per site, or less than 7 percent of all of the alert sites’ total activity.” The remaining activity, about 93 percent of the total scrambles, “generally involved visually inspecting unidentified aircraft and assisting aircraft in distress.” [General Accounting Office, 5/3/1994, pp. 4] In the two years from May 15, 1996 to May 14, 1998, NORAD’s Western Air Defense Sector (WADS), which is responsible for the “air sovereignty” of the western 63 percent of the continental US, scrambles fighters 129 times to identify unknown aircraft that might be a threat. Over the same period, WADS scrambles fighters an additional 42 times against potential and actual drug smugglers. [Washington National Guard, 1998] In 1997, the Southeast Air Defense Sector (SEADS)—another of NORAD’s three air defense sectors in the continental US—tracks 427 unidentified aircraft, and fighters intercept these “unknowns” 36 times. The same year, NORAD’s Northeast Air Defense Sector (NEADS) handles 65 unidentified tracks and WADS handles 104 unidentified tracks, according to Major General Larry Arnold, the commander of the Continental United States NORAD Region on 9/11. [American Defender, 4/1998] In 1998, SEADS logs more than 400 fighter scrambles. [Grant, 2004, pp. 14] In 1999, Airman magazine reports that NORAD’s fighters on alert at Homestead Air Reserve Base in Florida are scrambled 75 times per year, on average. According to Captain Tom Herring, a full-time alert pilot at the base, this is more scrambles than any other unit in the Air National Guard. [Airman, 12/1999] General Ralph Eberhart, the commander of NORAD on 9/11, will later state that in the year 2000, NORAD’s fighters fly 147 sorties. [9/11 Commission, 6/17/2004 ] According to the Calgary Herald, in 2000 there are 425 “unknowns,” where an aircraft’s pilot has not filed or has deviated from a flight plan, or has used the wrong radio frequency, and fighters are scrambled 129 times in response. [Calgary Herald, 10/13/2001] Between September 2000 and June 2001, fighters are scrambled 67 times to intercept suspicious aircraft, according to the Associated Press. [Associated Press, 8/14/2002]
Lieutenant General Norton Schwartz, the commander of the Alaskan NORAD Region at the time of the 9/11 attacks, will say that before 9/11, it is “not unusual, and certainly was a well-refined procedure” for NORAD fighters to intercept an aircraft. He will add, though, that intercepting a commercial airliner is “not normal.” [Air Force Magazine, 9/2011 ] On September 11, 2001, NEADS scrambles fighters that are kept on alert in response to the hijackings (see 8:46 a.m. September 11, 2001 and 9:24 a.m. September 11, 2001).

1990: Mohamed Atta Joins Muslim Brotherhood Linked Group
In 1990, after finishing his studies in architecture in Egypt, future 9/11 hijacker Mohamed Atta joins what is called an “engineering syndicate,” a professional or trade group. Like the school that trained many of its engineers, the syndicate serves as an unofficial base for the Muslim Brotherhood in Egypt, where the organization recruits new operatives and spreads its ideology. Other members of the 9/11 plot will also have connections to the Muslim Brotherhood at various points in their lives. [Washington Post, 9/22/2001; Observer, 9/23/2001; Newsweek, 12/31/2001]
1990: Security Chief Warns Port Authority that Terrorists Could Set Off a Truck Bomb in the WTC Parking Garage
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). [Parachini, 2000, pp. 190-191 ]
Mid- to Late-1990s: CIA Suffers ‘Brain Drain’
In the mid-1990s, the CIA suffers “brain drain,” as budget restrictions cause the agency to get rid of many of its most experienced officials. CIA official Michael Scheuer will later explain: “They called it a buyout program through the whole federal government, and they thought they were going to get rid of the deadwood. What happened was they lost the age-40-to-48 group of very strong potential senior officers, those people who couldn’t stand the bureaucracy anymore. They couldn’t stand the crap, so they retired, and we lost a whole generation.” In 1997, George Tenet becomes the new CIA director (see July 11, 1997) and he attempts to stop the loss of talent. He even initiates a massive recruitment drive for the CIA’s Directorate of Operations’ clandestine service. But according to a Vanity Fair article, “unfortunately, the training of these new spies remained very much old-school: they were taught how to operate undercover in European embassies, but not how to infiltrate Islamic terrorist cells.” Tenet’s choice for the latest deputy director of operations typifies the problem. His pick is Jack Downing, a 57-year-old veteran CIA officer who served as station chief in Moscow and Beijing during the Cold War. Scheuer will comment, “Downing was a Marine, and then he was a very, very successful officer during the Cold War, but he didn’t have a clue about transnational targets, and he didn’t like analysts.” [Vanity Fair, 11/2004]
Between 1991 and 2001: NORAD Exercise Simulates Crash into Famous US Building
At some point between 1991 and 2001, a regional NORAD sector holds an exercise simulating a foreign hijacked airliner crashing into a prominent building in the United States, the identity of which is classified. According to military officials, the building is not the World Trade Center or the Pentagon. The exercise involves some flying of military aircraft, plus a “command post exercise” where communication procedures are rehearsed in an office environment. [CNN, 4/19/2004]
1991: White House Is Protected from Airplane Attack During Gulf War
Time magazine reports in 1994, “During the Gulf War, uniformed air-defense teams could be seen patrolling the top floor [of the White House] with automatic rifles or shoulder-mounted ground-to-air missiles.” [Time, 9/26/1994] While a battery of surface-to-air-missiles remains permanently on the roof of the White House, the rest of these defenses are apparently removed after the war is over. [Daily Telegraph, 9/16/2001] Yet even though counterterrorism officials later call the alerts in the summer of 2001 “the most urgent in decades,” similar defensive measures will apparently not be taken. [US Congress, 9/18/2002]
1991: Private Security Report Indicates WTC Is Terrorist Target
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).
