And what did you finally conclude?

No conclusion was made. We never got deep into a discussion.

While I do not have any licenses in aviation, or formal training in
aerodynamics, I do know calculus, Newtonian physics, and theory of
gases, ...and the explanation simply did not make sense to me, not
even as a shallow-but-still-theoretically-truthful answer.

So is that supposed to make you especially qualified to know what the
truth is? Are you the only person on the planet who knows calculus,
Newtonian physics and the theory of gases?

No.

But as I stated, while I was not sure that I was right, the others
were sure that I was wrong.

You can
read the thread to see the type of responses I got. *Many of the rude
responses were one-liners from people whom I'd never met, presumably
pilots. Others came from pilots who vacillated between being
thoughtful and being rude, and the remaining came from those
interrupted the thoughtful responses because they felt that being rude
was most prudent for all.

Welcome to the Internet. If you can't stand the heat, get out of the
kitchen.

Sorry cannot.

I believe that, eventually, this group could be a forum for genuine
discussion about thinks like backwash and lift.
