A device for indicating urgent closing is provided in one of the flight deck and cabin, and a closing control part which closes information machines and equipment so that information regarding activity of the passengers in the cabin does not transmit to the flight deck when the urgent closing indication means indicates an urgent closing state. A device for communicating outside of the aircraft is provided at the cabin, allowing communication with the outside, so that suicidal-explosion terrorism can be prevented.
