April 2000 (B): US intelligence learns about an alleged bin Laden plot to hijack a 747. The source is a "walk-in" to the FBI’s Newark office who claims that he had been to a training camp in Pakistan where he learned hijacking techniques and received arms training. He also stated that he was supposed to meet five to six other individuals in the US who would also participate in the plot. They were instructed to use all necessary force to take over the plane because there would be pilots among the hijacking team. The plan was to fly the plane to Afghanistan, and if they would not make it there, that they were to blow up the plane. Although the individual passed an FBI polygraph, the FBI was never able to verify any aspect of his story or identify his contacts in the US. [Senate Intelligence Committee, 9/18/02]
