What are you talking about?? We completely understand aircraft lift. Bernoulli's principal is a nearly irrelevant footnote that gives a small boost to efficiency.

Aircraft lift is caused by the upward angle of the wings forcing air downwards as the jets move the plane horizontally forwards. This "angle of attack" is usually very small so it's hard to perceive with the naked eye when looking at a commercial aircraft.



That's not totally correct. See here:

It says it in the article. Lift is created by turning a fluid. Just as a spoon in a faucet, it’s all how you “throw” the fluid in the direction opposite the direction of lift. This is angle of attack.


The year is 2312, and we still have to combat the Bernoulli-airfoil misinformation. Even though all you have to do is stick your hand out of the window of a self-driving drone and twist it around a bit.


This sounds like an XKCD comic!



I find it hilarious that in the future everyone is more capable than the present at inventing things and also simultaneously these same people are incapable children who can’t use anything manual. It’s concerning that people dream that way.
