Check out the Alt text (hover) comment:

This a is a fun explanation to prepare your kids for; it's common and totally wrong.
Good lines include "Why does the air have to travel on both sides at the same time?" and "I saw the Wright brothers plane and those wings were curved the same on the top and bottom!"

The guy is an actual physicist.

Like with the conveyor belt, the number of supposedly expert resources that don't get this is amazing.

I'll add, "I had a tailwind, so I added airspeed on my landing."

The wing goes up because it pushes air down. No reason to try and explain anything more then that. It just confuses people and they walk away knowing less.

Or maybe the air pushes the wing up....or both!

Linked there is animation from NASA - that doesn't exactly explain it in a form that's easy to see - engineers just cannot simplify things.

[Capt. Geoffrey Thorpe]

Bernoulli's principle?

Which one? The real Bernoulli's principle or the fake one that gets falsely blamed on Bernoulli.
