The FAA gives 15 warnings to domestic airlines between January and August 2001, but about one general security warning a month had been common for a long time. [CNN, 5/17/2002] Even a government official later calls the content of these 15 warnings “standard fare.”
[Miami Herald, 5/17/2002] As one newspaper later reports, “there were so many [warnings] that airline officials grew numb to them.”
[St. Petersburg Times, 9/23/2002] In May 2002, in response to recent revelations about what was known before 9/11, the major airlines will hold a press conference claiming they were never warned of a specific hijacking threat, and were not told to tighten security. For instance, an American Airlines spokesman states that the airline “received no specific information from the US government advising the carrier of a potential terrorist hijacking in the United States in the months prior to September 11, 2001. American receives FAA security information bulletins periodically, but the bulletins were extremely general in nature and did not identify a specific threat or recommend any specific security enhancements.”
[Miami Herald, 5/17/2002] Bush administration officials later state that the terror information they are receiving is so vague that tighter security does not seem required. [Associated Press, 5/18/2002] However, it seems that even these general warnings are never passed on to airline employees. Rosemary Dillard, a supervisor for American Airlines, states, “My job was supervision over all the flight attendants who flew out of National, Baltimore, or Dulles. In the summer of 2001, we had absolutely no warnings about any threats of hijackings or terrorism, from the airline or from the FAA.”
[New York Observer, 6/20/2004] The content of these seemingly harmless warnings remain classified after 9/11. They are said to be exempted from public disclosure by a federal statute that covers “information that would be detrimental to the security of transportation if disclosed.”
