I hope you are pulling someone's leg, and that your are not that inept in
the field of aerodynamics and physics.
No, I'm quite serious.
The reduction in *pressure* on the upper surface of the wing cannot
produce any force except downward. A perfect vacuum over the entire
upper surface wouldn't produce any upward force, but simply *zero*
force; allowing the upward force on the lower surface to act alone.
Anyone who thinks that the pressure of a fluid on a surface can act in
any direction but towards the surface is simply wrong.
