We must be very careful how we describe "flying" on the wing. Please be courteous and avoid accusing people of not "having a clue," we can all learn something about aerodynamics, that is for sure!

For sure, the wing is not providing differential lift while flying in a perfect upline. The pressure is the same on either side of the wing if the plane is going straight up, and there is NO WIND.

I think this topic has surpassed the intent of the orginal question and may have become useless at this point. I don't like to post things in futility, but it seems there is some interest still out there.
