Air travel security method, system and device -- United States Patent: 6933851 という特許。
Abstract には、
A method of providing air travel security for passengers traveling via an aircraft comprises situating a remotely activatable electric shock device on each of the passengers in position to deliver a disabling electrical shock when activated; and arming the electric shock devices for subsequent selective activation by a selectively operable remote control disposed within the aircraft. The remotely activatable electric shock devices each have activation circuitry responsive to the activating signal transmitted from the selectively operable remote control means. The activated electric shock device is operable to deliver the disabling electrical shock to that passenger.とあります。
つまり、『航空機の運航上の安全を確保するために、それぞれの乗客にリモートコントロールで電気ショックを与えて動けないようにする手法、システム、装置』。
そんな旅客機、乗りたくない。
