each intrepretation is interesting

Here is a another one:
Lift is simply a momentary disturbance in otherwise equalized air.
The plate or wing or what have you traps air - or hangs onto it . At the same time - the air resists being unequalized.
It will take the easiest path possible to avoid it
The unequal pressure we make, can be useful- or not.
It can be used as lift.
In any case the nature of fluids is that if uncontained - and uninfluenced - an equalization of pressure immediately occurs.
Make a pressure difference and the higher pressure will try to move anything in it's path to re equalize.
High moves to low just as heat moves to cold.
(in space there is no heat and no pressure - thot I would throw that in -
Nobody has mentioned gravity in all this
OK back to sleep
