Abstract:
A counter hijacking system for an airliner that includes a fuselage divided into a passenger compartment and a cockpit separated by a bulkhead includes a series of concealed receivers in the passenger compartment that are interconnected to a cockpit alarm and activated by portable transmitters carried by the flight attendants to signal a dangerous situation occurring in the passenger compartment whereupon the pilot or co-pilot can engage a toggle switch that opens a flow valve so that a knockout agent can be introduced into the passenger compartment via the fuselage oxygen lines for rendering the flight attendants, the passengers, and the hijackers or terrorists unconscious while personnel in the cockpit remain conscious and unaffected as their oxygen is provided from a separate source. After a predetermined time the crewmembers enter the passenger compartment, revive the flight attendants by administration of a counter agent, and secure the hijackers or terrorists with restraints and/or stun guns after their identification by the revived flight attendants.
