Actually, that whole "makes air go faster over the top" thing is still true. It's the "equal transit time" explanation that's been thoroughly debunked. But pressure differential caused by Bernoulli's principle is still part of what generates lift, along
with Newton's laws.
EDIT: The most hilariously confusing (and wrong) explanation ever given about lift can be found at around 4:15 in this video:
Seriously funny stuff.
Basically the principle is, if you throw matter away from you, it results in an equal force in the opposite direction.
The engine suck in air and expel that at, creating an equal force in the opposite direction. When the airplane moves fast enough, the wings bend the air flowing over them downward creating an opposite force upwards. That force helps, but is not neccesairy
for flight, if you have a big enough engine. That's the principle thrust vectoring relies on. If you create a large enough force, you dont need lift.
The bigger the wing, the more air you can bend. I don't exacly understand how the curving of the wing comes into play.
