I am told that what is used to de-escalate drug crazed people is to put them in a soft walled room coloured bubblegum hot pink. While it may be cost prohibitive to line all interior panels with 3/4 inch of foam the “hot pink” colour solution might be just what’s needed. It could be applied using poster paint which is water soluble and could easily be removed as times change. While this colour selection may offend some folks it will probably put the nutbars in a comatose state for the duration of the flight. At this point it would be rather easy to apply the duct tape.
