We shouldn’t rashly fly off the handle here.
What is needed is a trap door type assembly where the ‘attacker’ is placed in it then when the deck secured, open the bottom of the hatch and let him leave the flight.
That way the flight can continue on and the other 200 or so passengers that were behaving themselves do not have to be punished along with the 1 misbehaver.
Sort of a reverse 3rd grade. Just punish the offender and let the others be.
The main (and only) reason I wont fly is if by chance, was in this situation, the wasted time while everyone on the flight is checked and rechecked and your destination is delayed.
Of course I would probably be arrested for assaulting the SOB.
I would say put the trap-door forward of an engine, but that would endanger the remaining passengers. It would certainly do the trick though.
