I have always thought that the idea that the wing top shape is what keeps the plane in the air is something along the same lines as the argument that if a tree falls in the forest and no one is around to hear it ,there is no noise. Oh really? If vacume on top of the wing is all there is to it,then a bumblebee could not fly! He is to heavy for the limited amount of vacume that is available. Or you could say the to skip a flat stone on the water the vacume on top of the stone is what keeps from sinking into the water. What say you to that?!
