Patent# 3,841,328 the Hijack Injector, assumes that all hijackers are sedentary or at least can be encouraged to be so. Given that it might be possible for that situation to occur (perhaps it could be assured if they are tired and hijacked a few too many planes that day). This patent provides just punishment and a way to take action and control over what could be a fatal situation via a hypodermic needle injector built into every seat on the plane! This passenger-disabling apparatus mounted in and under every airplane seat and remotely actuated by a pilot or a crewmember is comprised of a solenoid actuated seat belt buckle lock in combination with an inflatable seat back and hypodermic injection apparatus.
