If so, good. But you should consider the plafon as I meant AKA Dome.
I understand what you meant. But that is not what the pilot meant. As "plafon" refers to an aviation/weather term meaning lowest cloud layer, not an impenetrable "dome". And the pilot was obviously an aviator using aviation language as they are called upon to do, universally.
(You are not an aviator, at least I hope not because according to you, you would have lasted one flight and killed yourself and everyone else onboard because you didn't believe your altimeter readings).
So you can make up whatever a word and your meaning for it is, but that doesn't mean you can apply yours to a pilot using the term that is universally standardized and used in aviation to mean something completely different.
Without closed system of dome, no action-reaction mechanism will occure, so that the conventional aero dynamic theory will be left confusing and contadictory.
Open air cannot give feedback force for a thrust. It take a "wall" in a closed system to realize an action reaction mechanism.
Only an example of why you should accept the dome theory. 👌
This one comes up a lot in Domer theory, a closed system, objects need a "wall" to move, etc. Since you're referring to action/reaction specifically there's this little experiment - A slider held together with rubber bands, apparatus resting on some low friction beads. Snip the connecting band, the sliders slide apart, action/reaction, the half-mass slider on the right moves double speed to the full size mass on he left.
Now aside form the physics of simple action/reaction exemplified by the experiment, let's talk domes and closed systems. The same result would occur if you moved that experiment into a bigger room, or smaller room, all of which would be considered
closed systems of varying size - One would expect the push off within the smaller "closed system" (aka, smaller room) would yield a different result from inside the larger "closed system" (aka, larger room). It doesn't.
What I suggest you need to do is square your notions against actual events, things, experiments, and then ask yourself if logically, rationally, at a distance, your conclusions actually make sense.
