John O’Neill, a senior FBI agent, tells congressional staffers there are no threats to aviation in the US. The staff of the Senate Intelligence Committee has asked the FBI, the director of central intelligence, and the Federal Aviation Administration (FAA) for a briefing about threats to civil aviation. O’Neill goes to the Hart Senate Office Building in Washington, DC, to respond to this request on behalf of the FBI. Cathal Flynn, the FAA’s associate administrator for civil aviation security, who goes on behalf of the FAA, will later recall that at the briefing, Senate Intelligence Committee staffers ask, “What are the indications—or what are the threats—to aviation?” In response, according to Flynn, “John O’Neill said there are none.” [9/11 Commission, 9/9/2003 ; 9/11 Commission, 1/27/2004] Bruce Butterworth, the FAA’s director of civil aviation security operations, who is apparently at the briefing, will similarly describe O’Neill’s response. He will say he “recalled FBI agent John O’Neill’s testimony to the Senate Intelligence Committee wherein he was unwilling to corroborate FAA claims about credible threats to civil aviation.” [9/11 Commission, 9/29/2003 ]
FBI Has Learned of ‘Indications’ of Threats to Aviation – Flynn finds O’Neill’s response to the Intelligence Committee staffers odd, since, he will say, the FBI has learned of a “few indications” of possible threats to aviation, such as a suspicious individual trying to get “a job with airport access” at Los Angeles International Airport. He writes a note to O’Neill, reminding him about this incident. But, according to Flynn, O’Neill “looked at the note” and “still didn’t say anything, didn’t change what he had said.” As the two men are leaving the briefing, Flynn asks O’Neill about the incident and O’Neill tells him there was “nothing to it.” [9/11 Commission, 9/9/2003 ; 9/11 Commission, 1/27/2004]
O’Neill Is the FBI’s ‘Most Committed Tracker of Osama bin Laden’ – It is unclear when this briefing takes place. It presumably occurs sometime between July 1995 and September 2000—the time period during which Butterworth is the FAA’s director of civil aviation security operations. [9/11 Commission, 9/29/2003 ] According to Flynn, O’Neill is “the head of antiterrorism for the FBI” when the briefing is held. [9/11 Commission, 1/27/2004] This suggests that it takes place sometime between January 1995 and January 1997, when O’Neill is chief of the counterterrorism section at the FBI’s Washington headquarters. [Federal Bureau of Investigation, 9/11/2006] During his time working for the FBI, O’Neill becomes “the bureau’s most committed tracker of Osama bin Laden and his al-Qaeda network of terrorists,” according to the New Yorker. [New Yorker, 1/14/2002] Journalist and author Murray Weiss will write that O’Neill “had reiterated since 1995 to any official in Washington who would listen” that “he was sure bin Laden would attack on American soil.” [Weiss, 2003, pp. 360]
