May 16, 2002 (C): In response to all of the revelations about what was known before 9/11 (see May 15, 2002), the major airlines hold a press conference saying they were never warned of a specific hijacking threat, and were not told to tighten security. For instance, an American Airlines spokesman states 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 Sept. 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, 5/17/02] The FAA gave 15 warnings to the airlines between January and August 2001, but about one general security warning a month had been common for a long time. [CNN, 5/17/02] Even a government official called these warnings "standard fare." [Miami Herald, 5/17/02]
