Ignoring them until they tire themselves out.
Like imagine you’ve got them on the ground in the aisle and need to get them restrained in a seat… muzzling seems like a good plan to me.
No such thing exists on an airplane so you would have to tie them to the seat somehow.
While we could assign airline attendants a concrete block as part of their kit, concrete blocks weigh quite a bit and are not FAA approved.
I therefore recommend we go the duct tape route.
It's such a shame that there's no way we could impose some sort of requirement, a sort of passport if you will, on passengers that would eliminate just about all of this. But I can dream.
Isn't this sort of thing fairly rare? Usually when things are "in the news" it means it fairly uncommon, because if it happens frequently it's no longer "news".
I haven't flown since COVID though, and never any domestic US flights either.
I haven't flown either and I have no plans to do so in the near future until either a vaccine passport system is imposed or the pandemic ends. I can wait.
However I think that a ventilated bag over the head is probably safer. Blocking the mouth is risky.
