Backwash Causes Lift?

I believe it should be possible to explain a venturi tube, Bernoulli's

pages of written text, with pictures, using no formulas, not even
grade-school mathematics.

Commonly done in many texts. You just haven't read them yet.

Which texts are those?

I have read some texts:

1. Jeppesen got it wrong.
2. Rod Machado got it wrong.
3. That link that with the funny color lines that was posted in this
thread got it wrong.
4. If you do search in Google for "Bernoulli" + "faster" + wing +
lift, you will see 1000's of pages that got it wrong.

Plus I watched 3 CFI's at my ground school, the one I paid money to
teach me the theory of flying, get it wrong at the whiteboard.

And of course, if the NASA paper is true, then there are even people
in this group who got it wrong.

Until 3 days ago, the number of people who had gotten (partially)
right was 1. The number of stories I had heard from people who got it
wrong was probably about 60-70.

After reading the link that Jim Logajan posted, the number of people
who are saying it's one way is 2. The number of people who are saying
it is the exact opposite is still 60-70.

Which textbooks would you believe if you had read 1 saying one thing,
and more than 10 others saying the exact opposite?
