1996 (D): Having found a business card of a US flight school in the possession of Bojinka plotter Abdul Hakim Murad (see January 6, 1995), the FBI investigates the US flight schools Murad attended. [Washington Post, 9/23/01] He had trained at about 6 flight schools off and on, starting in 1990. Apparently they stop their investigation when they fail to find any other potential suspects (see May 18, 1998). [Insight, 5/27/02
