Lift explanation in it's true form is an extremely complicated issue.
Attempts to explain it in one simple sentence is usually very confusing
to a new student pilot.
The closest thing to a one sentence explanation I have seen is that lift
is created by turning an airflow.
Of course this covers Newton and leaves Bernoulli out there to be
discovered later on as one finally comes to realize that you can't turn
the airflow without having the pressure difference :-)


I hadn't looked into this much in recent years and the article rekindled
some interest. I hadn't even heard of the "equal transit theory" before you
mentioned it, but a short search brought up a detailed explanation of
exactly what you are talking about, and turning the airflow is ultimately
what it's all about for both Bernoulli and Newton.

It's a complicated issue that many in aviation accidentally make even
more complicated by delving too deeply into their physics books instead
of learning to shave with Occam's Razor :-))
