You don’t let crazy people act out. You don’t know who they may hurt. Could stab someone with a pen. Restrain them immediately. Duct tape is a great solution. Tape them to the seat, and continue to the destination. Don’t divert the flight and inconvenience all the other passengers
Again, I agree, but something bad can happen while futzing with the door.
And who was carrying a roll of duct tape with them on the plane? That was pretty incredible?
