In September 1994, “Working out of the Philippines, [World Trade Center bomber Ramzi] Yousef conceives three plots. (1) He will kill Pope John Paul II on a visit to Manila in January 1995. (2) He will create an undetectable liquid-based bomb to be smuggled on board eleven U.S. jumbo jets entering the United States from Asia [later known as the ‘Bojinka’ plot]. (3) With Abdul Hakim Murad, the pilot trained at four U.S. flight schools, Yousef will coordinate the training of Islamic pilots at U.S. schools who will then commandeer airliners and fly them into buildings in America. This third plot becomes the blueprint for the 9/11 attacks.” [The 15th of the month used for date sorting purposes only.]
