Did al-Qaida recruit warn FBI before 9/11?

"LONDON - More than a year before 9/11, a Pakistani-British man told the FBI an incredible tale: that he had been trained by bin Laden's followers to hijack airplanes and was now in America to carry out an attack. The FBI questioned him for weeks, but then let him go home, and never followed up. Now, the former al-Qaida insider is talking."

"Congress' 9/11 report confirms that in April, 2000, an unnamed 'walk-in' told the FBI he 'was to meet five or six persons' — some of them pilots — who would take over a plane and fly to Afghanistan, or blow the plane up. The report adds that the 'walk-in' passed a lie-detector test."
