I've at least examined it theoretically.

Anyway, all the air pressure on our planet results from gravity, not
temperature or confinement or anything else.

I dont doubt you analysed it Anthony, but you still havent seen, or
aren't willing to admit , that you had it all wrong. Now what has the
SOURCE of the air pressure got to do with the discussion ? Change of
subject no 3.
Last chance Anthony. Why would the non containment of the atmosphere
prevent the ideal gas law in its form used by me not allow one to
calculate the air density in the vicinity of an airport? That is
what you have stated twice remember Anthony?
