 Also, passengers will frequently open an exit as soon as evacuation begins which may result in them evacuating into danger.This occurred in the Ryanair engine fire in Stansted Airport in 2002, where passengers evacuated themselves onto a burning wing, despite airport fire services personnel shouting at them to return inside the aircraft and evacuate via a usable exit.Typically, these problems do not occur at floor level, full sized, exit doors because these are operated by flight attendants in an emergency who have extensive emergency training.
