When I thought there was higher pressure under the wing that pushed the plane up, I was happy. When I started thinking, instead, about little vacuum vortices above the wings pulling them up instead, I was suddenly much less comfortable with the whole proposition. Given the options and the limited effect on my daily life, I’m gotta go with Newton over Bernoulli on this one.
We know vacuums don’t “pull” things. Instead it’s air pressure elsewhere that isn’t balanced by the vacuum that moves things in the direction of the vacuum.
Speak for yourself. I’m a student pilot and most of my instructors (who are either retired airline pilots or are trying to build up flight hours to qualify for an airline job) don’t understand the science behind it. To be fair, understanding the science doesn’t really help you fly a plane…
It is both, but the pressure one contributes more to lift. You can see this when a wing stalls, the airflow separates from the upper surface and the pressure difference is gone. The angle of a stalled wing still means air is directed downwards, but the overall lift is much smaller.
Hardly! People board airplanes every single day and we still don’t fundamentally understand the mechanisms of how lift works.

¿Porque no los dos?
Wait how do we not know how lift works?
I think it’s more so that we know HOW it works but we don’t know WHY it works
I don’t get it, how can you know how it works but not how? Or is it some philosophical why are the laws the way they are?

How do we not know how gravity works??
It’s elusive, man. Lack of symmetry really fucks with our shit, yo.
We don’t? I thought we kind of did
No we don’t.

I heard that it was just the angle of the wings redirecting the air downwards as reaction mass, like how a rocket engine shoots air downwards.

At least that is what I’ve been told anyways
