A foreign intelligence agency warns the FBI’s New York office that Arab militants plan to fly a bomb-laden aircraft from Libya into the World Trade Center. The FBI and the FAA do not take the threat seriously because of the state of aviation in Libya. Later, other intelligence information will connect this group to al-Qaeda. The CIA will include the same information in an intelligence report. [New York Times, 9/18/2002; US Congress, 9/18/2002; US Department of Justice, 11/2004, pp. 97-98 
] An FBI spokesperson later says the report “was not ignored, it was thoroughly investigated by numerous agencies” and found to be unrelated to al-Qaeda. [Washington Post, 9/19/2002] However, the 9/11 Congressional Inquiry will come to the conclusion that the group in fact did have ties to al-Qaeda. [New York Times, 9/18/2002; US Congress, 7/24/2003 ]
August 1998-Late-September 2001: Inexperienced Manager Heads FAA’s Boston Security Field Office
Mary Carol Turano is appointed director of the Federal Aviation Administration’s Boston Civil Aviation Security Field Office (CASFO). This is the office that oversees security at Logan Airport, from where Flights 11 and 175 depart on 9/11. Yet Turano has little experience in airport security, and has not even begun the basic training that all FAA special agents must undergo. During her tenure, according to an agent who is assigned to Logan, staff that document security violations become frustrated, as she allows violations to accumulate without taking appropriate action. After 9/11, it will be revealed that she lacks the identification badge necessary for unescorted access to secure areas. An official familiar with airport security procedures will comment, “An organization does well what a commander checks, and how can you check what they do if you don’t have a ramp access badge?” Turano is subsequently reassigned. [Associated Press, 9/29/2001; Boston Globe, 9/29/2001; WBUR (Boston), 10/4/2001; Thomas, 2003, pp. 61; 9/11 Commission, 3/11/2004 ] Logan Airport’s poor record for security continues while she heads CASFO (see 1991-2000 and 1997-September 1999).
October 8, 1998: FAA Warns of Al-Qaeda Threat to US Civil Aviation
The FAA issues the first of three warnings this year to US airports and airlines urging a “high degree of vigilance” against threats to US civil aviation from al-Qaeda. It specifically warns against a possible terrorist hijacking “at a metropolitan airport in the Eastern United States.” The information is based on statements made by Osama bin Laden and other Islamic leaders, and intelligence obtained after the US cruise missile attacks in August. All three warnings come in late 1998, well before 9/11. [Boston Globe, 5/26/2002]
December 4, 1998: Clinton Warned ‘Bin Laden Preparing to Hijack US Aircraft’ Inside US
On December 4, 1998, an item in President Clinton’s Presidential Daily Briefing (PDB) is titled, “Bin Laden Preparing to Hijack US Aircraft and Other Attacks.” The PDB says “Bin Laden and is allies are preparing for attacks in the US, including an aircraft hijacking to obtain the release of Sheikh Omar Abdul-Rahman, Ramzi Yousef, and Muhammad Sadiq ‘Awda. One source quoted a senior member of Al-Gama’a al-Islamiyya (IG) saying that, as of late October, the IG had completed planning for an operation in the US on behalf of bin Laden, but that the operation was on hold. A senior bin Laden operative from Saudi Arabia was to visit IG counterparts in the US soon thereafter to discuss options-perhaps including an aircraft hijacking.” The same source says bin Laden may implement plans to hijack US aircraft before the start of the Muslim holy month of Ramadan on December 20 and that two members of the operational team had evaded security checks in a recent trial run at a New York airport. A possible different source says that in late September, Mohammed Shawqui Islambouli, brother of the assassin of Egyptian President Anwar Sadat and described in the PDB as an IG leader, was planning to hijack a US airliner during the “next couple of weeks” to free Abdul-Rahman and other prisoners. The PDB also says that “some members of the bin Laden network have received hijack training, according to various sources, but no group directly tied to bin Laden’s al-Qaeda organization has ever carried out an aircraft hijacking. Bin Laden could be weighing other types of operations against US aircraft.” The PDB mentions other bin Laden related threats, including recent reports that the IG has obtained surface-to-air missiles and intends to move them from Yemen to Saudi Arabia to shoot down aircraft. [Washington Post, 7/18/2004; 9/11 Commission, 7/24/2004, pp. 128-130] The private intelligence group Stratfor will later say that, in addition to his ties with IG, Islambouli worked with bin Laden in the Maktab al-Khidamat charity front in Pakistan and is believed to have lived in Afghanistan in the 1990s as “part of the group of key Egyptian advisers surrounding bin Laden.” Islambouli will formally join with al-Qaeda in 2006. [Stratfor, 8/10/2006] In early 1998, the CIA ignored information from a recently retired CIA agent that claimed 9/11 mastermind Khalid Shaikh Mohammed was in a terrorist cell with Islambouli, both were experts on plane hijackings, and were planning to hijack planes (see Early 1998). Perhaps not coincidentally, on this same day, CIA Director George Tenet issues a “declaration of war” against al-Qaeda in a memo to the US intelligence community (see December 4, 1998). Also on this day, counterterrorism “tsar” Richard Clarke holds a meeting of his interagency Counterterrorism and Security Group (CSG) to discuss the threat. The group agrees that New York City airports should go on a maximum security alert that weekend and security should be boosted at other East Coast airports. The FBI, FAA, and New York City Police Department get versions of the PDB report. Later in December and again in January 1999 the source says the hijacking has been postponed because two operatives have been arrested in Washington or New York. But the FBI is unable to find any information to support the threat nor is it able to verify any arrests similar to what the source described, and the source remains mysterious. The high alert in New York airports is canceled by the end of January. [9/11 Commission, 7/24/2004, pp. 128-130] This PDB will be mentioned in President Bush’s famous August 6, 2001 PDB, but mentions that US officials “have not been able to corroborate” the plot (see August 6, 2001).
August 4, 1999: FAA Considers Suicide Hijacking Possibility: Al-Qaeda Could Hijack Jet and ‘Slam It into a US Landmark’
The FAA’s Office of Civil Aviation Security Intelligence sends an internal memo summarizing the al-Qaeda hijacking threat. After reciting information available on the topic, a few principal scenarios are presented. One of them is a “suicide hijacking operation.” The 9/11 Commission will comment on this and another memo the previous year, “In 1998 and 1999, the FAA intelligence unit produced reports about the hijacking threat posed by bin Ladin and al-Qaeda, including the possibility that the terrorist group might try to hijack a commercial jet and slam it into a US landmark.” However, FAA analysts consider this an option of last resort, because “it does not offer an opportunity for dialogue to achieve the key goal of obtaining [Sheikh Omar Abdul-Rahman] and other key captive extremists.” [9/11 Commission, 7/24/2004, pp. 345, 561; 9/11 Commission, 8/26/2004, pp. 53]
October 25, 1999: Golfer Payne Stewart Dies in Plane Crash; Incident Raises Questions about Shooting Down Off-Course Planes
A runaway Learjet crashes near Mina, South Dakota, after flying on autopilot for several hours. On board is champion golfer Payne Stewart, along with five others. It is believed the accident is due to a loss of cabin pressure at high altitude, which would have caused all on board to go unconscious from lack of oxygen. [ABC News, 10/25/1999; Washington Post, 10/26/1999; National Transportation Safety Board, 11/28/2000] After air traffic controllers lost contact with the plane, it was tracked by the Federal Aviation Administration (FAA), assisted by several Air Force and Air National Guard fighters and an AWACS radar control plane, up until when it crashed. It was also tracked on radar screens inside the National Military Command Center in the Pentagon. [CNN, 10/26/1999] The Learjet had departed Orlando, Florida at 9:19 a.m., bound for Texas. The FAA says controllers lost contact with it at 9:44 a.m. [Washington Post, 10/26/1999] , but according to a later report by the National Transportation Safety Board (NTSB) the plane first failed to respond to air traffic control at 9:33 a.m., after which the controller repeatedly tried to make contact for the next 4 1/2 minutes, without success. [National Transportation Safety Board, 11/28/2000] NORAD’s Southeast Air Defense Sector was notified of the emergency at 9:55 a.m. [9/11 Commission, 7/24/2004, pp. 459] At 10:08 a.m., two F-16 fighters from Tyndall Air Force Base, Florida that were on a routine training mission had been asked by the FAA to intercept the Learjet, but never reached it. At about 10:52 a.m., a fighter from Eglin Air Force Base, Florida, was directed to within 9 miles of it, and at around 11:00 a.m. began a visual inspection of the plane. It accompanied the Learjet from 11:09 to 11:44 a.m. At 11:59 a.m., according to early accounts, four Air National Guard fighters and a refueling tanker from Tulsa, Oklahoma were told to chase the Learjet, but got no closer than 100 miles from it. However, the NTSB later claims that two Tulsa fighters were with it between 12:25 and 12:39 p.m., and were able to visually inspect it. At 12:54 p.m., two Air National Guard fighters from Fargo, North Dakota intercepted the Learjet. Soon after 1:14 p.m., it crashed in swampland, after spiraling to the ground. [Washington Post, 10/26/1999; Associated Press, 10/27/1999; National Transportation Safety Board, 11/28/2000] During its flight, the FAA had routed air traffic around the Learjet, and made sure no other planes flew beneath it, due to the danger of it crashing. [Associated Press, 10/26/1999] There is some discussion as to what could have been done had the plane been on a collision course with a populated area, with CNN reporting, “[O]nly the president has the authority to order a civilian aircraft shot down.” Pentagon spokesman Ken Bacon says the military has no written instructions for shooting down manned civilian planes. According to a 1997 military instruction, the shooting down of unmanned objects such as missiles requires prior approval from the secretary of defense. [US Department of Defense, 7/31/1997 ; CNN, 10/26/1999] A Pentagon spokesman says the fighters that monitored the Learjet had no missiles, but two other fighters on “strip alert” at Fargo had been armed but didn’t take off. [CNN, 10/26/1999] The 9/11 Commission will later compare NORAD’s response to this incident with its response to Flight 11 on 9/11, and claim: “There is no significant difference in NORAD’s reaction to the two incidents.” [9/11 Commission, 7/24/2004, pp. 459]
April 27, 2000: FAA Advisory Warns of Increased Risk of Terrorist Hijacking
The FAA issues an advisory to airports and air carriers, setting forth its views on the hijacking threat. The advisory states that while conditions for hijackings of airliners had been less favorable in the 1980s and 1990s, “We believe that the situation has changed. We assess that the prospect for terrorist hijacking has increased and that US airliners could be targeted in an attempt to obtain the release of indicted or convicted terrorists imprisoned in the United States.” However, “the terrorist hijacking of a US airliner is more probable outside the United States due to access to safe havens.”

August 2000: Improvements to GPS Technology Bring Pilotless Aviation Closer to Reality
After a successful test, the FAA makes an enhancement to the Global Positioning System (GPS) called Wide Area Augmentation System (WAAS) available to some aviation users. WAAS improves the accuracy of GPS data by correcting some known measuring errors. “The system demonstrated one to two meters horizontal accuracy and two to three meters vertical accuracy throughout the contiguous United States,” says the FAA. The system will be operated by Raytheon. [Federal Aviation Administration, 8/24/2000] The deployment of WAAS is only one of many technological advances that could lead to pilotless aircraft navigation, including takeoff and landing. Tests have shown that landing by autopilot is possible (see also August 25, 2001). [Spinoff, 1998; Federal Aviation Administration, 8/13/1999; Rockwell Collins, 10/5/1999] WAAS also has non-aviation uses. It will be used during the rescue effort at Ground Zero. “[A]t the World Trade Center, rescue teams used WAAS to survey the site during the recovery program,” according to Avionics Magazine. [Avionics Magazine, 2/1/2002] After 9/11 there will be some speculation that the hijackers used GPS to navigate to their targets (see (September 12-17, 2001)). Some press reports will claim that 9/11 hijacker Mohamed Atta was at the WTC the day before the attacks to gather GPS data (see September 10, 2001).
December 2000: FBI and FAA Claim Threat of Terrorists Targeting US Aviation Is Low Despite Information Suggesting Otherwise
The FBI and FAA jointly publish the yearly National Intelligence Estimate report mandated by Congress. It reads, “FBI investigations confirm domestic and international terrorist groups operating within the US but do not suggest evidence of plans to target domestic civil aviation. Terrorist activity within the US has focused primarily on fundraising, recruiting new members, and disseminating propaganda. While international terrorists have conducted attacks on US soil, these acts represent anomalies in their traditional targeting which focuses on US interests overseas.” This differs from assessments in previous years that suggested there were groups targeting domestic aviation. The 9/11 Congressional Inquiry will conclude that assessment is “relatively low… notwithstanding historical intelligence information to the contrary.” [US Congress, 9/18/2002]
December 4, 2000: Special Forces Commander Appointed FAA Security Chief
US Army Lieutenant General Michael A. Canavan is appointed associate administrator for civil aviation security at the Federal Aviation Administration (FAA), a position that includes being the “hijack coordinator” (see 8:30 a.m. September 11, 2001). [Federal Aviation Administration, 11/2000] In early 1998, Canavan participated in reviewing a CIA plan to capture Osama bin Laden in Afghanistan. He was then the commander of the Joint Special Operations Command (JSOC), which oversees the military’s counterterrorism operations and covert missions. He objected to the plan, saying it was too complicated for the CIA and “out of their league.” [9/11 Commission, 7/24/2004, pp. 113] The plan was later canceled (see 1997-May 29, 1998). It is not known if Canavan’s appointment at the FAA is related to his prior involvement in counterterrorism or to any intelligence that al-Qaeda might target civil aviation. He will leave the post in October 2001, after only 10 months, reportedly after clashing with other FAA officials. [Los Angeles Times, 10/13/2001]
