Factual error: When Sully decides to land in the Hudson River, the aircraft is approaching the George Washington Bridge the Ground Proximity Warning System advises to the pilots "Obstacle, Obstacle." This is correct; however, after the aircraft clears the bridge, the system then announces "Clear of conflict." This is incorrect, because the GPWS doesn't advise when clear of terrain. The Traffic Collision Avoidance System advises when clear of conflicts, which is only between aircraft.
