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]
