The fact that the OP has difficutly picturing it is not uncommon, may people have problems with the principal the the FASTER something moves, the less pressure it has, it seems contradictory. However, the speed of the plane, in combination with the redirection of air downward + decreased pressure above it causes it to lift.

If the bernoulli effect was A MYTH, it would take far more power then what is used to lift standard designed aircraft into the air.
Read the NASA article. The Bernoulli Effect is not what makes the plane fly. The air flows faster over the top of the wing, yes, because of the angle and the downward curve at the rear-- airflow on the bottom is compressed because it hits the underside and slows down relative to the plane. But the air speed difference is a tiny tiny contributor. It's not the majority or even a major portion of lift.

Redirection of flow is what creates lift.

If you know of a plane that can fly at 0 degrees wing pitch, post it.
