Gents, I take on board all the caveats and I am only SLF ... but having been scared silly by a minor contretempts taking place between the front seat occupants of a car when I most certainly did NOT feel safe I would be terrified by the prospect of something like this happening up front in an aircraft when there is a lot less chance of pulling over for everyone to have a chance to calm down.If it DID happen in any way shape or form, I would feel a lot safer knowing measures had been taken to prevent it in the future.
