July 18, 2001: FBI, FAA, and State Department Issue Warnings

The FBI issues another warning to domestic law enforcement agencies about threats stemming from the convictions in the millennium bomb plot trial. The FAA also issues a warning to the airlines, telling them to “use the highest level of caution.” [CNN, 3/2002] This is another one of 15 general warnings issued to airlines in 2001 before 9/11 (see January-August 2001), but it is more specific than usual. [CNN, 3/2002; CNN, 5/17/2002] Also on this day, the State Department issues a public warning of a possible terrorist threat in the Saudi Arabia region. [9/11 Commission, 7/24/2004, pp. 259, 534]
