Sorry LG, but the wing is not the pump. The engine is the pump, and the wing is a fixed passive reactor. Ultimately, the force of lift comes from the combustion chamber of the engine. (or in a glider, from the combustion chamber in the tow plane)

LOL I think we are carrying this analogy a little too far : )

I am truly amazed at the power of the combustion chambers in the tow plane yesterday! I dropped off at the end of Heber's runway yesterday, probably 800' AGL and yet I managed to ride a wave to 30k. I think I will have to congratulate the designer of that perpetual motion machine, he single handedly has solved the energy crises : )
