I see. You are not lookng at the wing as a system, but taking an
observation at one point only, without reguard to what is happening
around
it.

Point made.
Nope.

I'm making the point that the upper surface contributes absolutely *no*
lifting force.

None.

Zero.

In fact, it provides a downward force. Every time.

Sorry, Alan, old boy, I find must disagree.
Disagree all you want, it won't make the upper surface of the wing
experience anything but a downward force.

In actuality, BOTH surfaces are below ambient pressure.
('splain why?)
Bernoulli.

But without that reduction of the pressure across the top curve of the
wing,
the pressure below it can't do much at all, can it?
Which I never disagreed with.

But anyone who thinks the upper surface of the wing is experiencing
anything but a downward force is just sadly misinformed.

Ok, be that way.

Be what way: accurate? Thanks, I think I will.

I actually see what you are trying to say.
And, have no real issues with it.

Then why say: "I find I must disagree".

Myopic, but not technically incorrect.

Not myopic: accurate. Understand the world AS IT IS.

Einstein's greatest gift what that of Relativity.
Each has his own unique perception based on location
relative to an event.

Each sees something different - but ALL can understand
the other's perceptions.

And here you are claiming all truth...
