It is unsafe in the confined of the plane not to put on a mask to protect others from their infection, if any. Americans like to think about themselves and not think about others.

They should know that their wearing of a mask is to protect from their own infection and not to protect the other persons from infecting them. If a person removes their mask, they are at risk of being infected from other unmasked persons, too.

Hence, wearing a mask in a confined space in the plane should be the first line of defense for any person inside the plane. They can unmask or remove their mast when they are in the open air environment where if they kept with the gap of a distancing, there is no need to worry of infection.
