"An anti-hijacking system for an airplane to be operated during flight," reads Pizzo's patent.
Actually, the Annals of Improbable Research at Harvard, which awards the Ig Nobel, had to reach back in time for this one. The patent was awarded in 1970.
A much easier solution for flight disruptions, which are usually solo efforts, can be described as an “aluminum bathtub”, underneath the floor.
Once the disruptive individual has been controlled somewhat, open the door on the floor, shove him in, then shut the door.
And everyone walk the dinosaur.
I would give them a narrow little edge to hang onto until their fingers gave out.
“Yo, raghead - would you mind standing right over THERE, please”
