The Bojinka plot (; ) was a large-scale, three-phase attack planned by Islamists Ramzi Yousef and Khalid Sheikh Mohammed for January 1995. They planned to assassinate Pope John Paul II, blow up 11 airliners in flight from Asia to the United States with the goal of killing approximately 4,000 passengers and shut down air travel around the world, and crash a plane into the headquarters of the CIA in Fairfax County, Virginia.
