On 11th September 2001, the world watched in horror as two hijacked American Airlines planes were flown into The Twin Towers, devastating the lives of thousands. But what exactly happened in those 60 minutes leading up to the moment when the first plane hit the World Trade Centre? Last Hour of Flight 11 uses a real-time split-screen format to examine that fateful hour. Experience the pulse-pounding countdown from the moment that the passengers boarded Flight 11 to the split second before the plane hit the Twin Tower. That evening, FBI agents found two black cases belonging to Mohammed Atta that had failed to be put on Flight 11 in time for its departure. Within these cases were videos of pilots' tours, a hand-held flight computer, a Koran and five sheets of Arabic script detailing Atta's plan of action for that day. This programme uses Atta's chilling prescription for death in voice over as the minutes unfold from the perspectives of various key people involved; the terrorists on the aircraft; the hostesses making their telephone calls to the ground and ground control at Logan airport.
