    The whole premise of wings producing lift because of faster air over the top of the wing makes the pressure drop as opposed to the bottom is not technically correct. While this indeed happens, it's not what lifts the airplane into the sky. The way wings produce lift is simply by directing the flow of air over the top of the wings downward (the same way flowing water will "stick" to a curved rock as it goes around it). Once the mass of air directed downward becomes greater than the mass of the aircraft itself, the plane is lifted. It's simply an employment of Newton's 3rd law of physics (every action produces an equal and opposite reaction).
    If you doubt this, just consider why it is an airplane must travel fast in order to produce enough lift to leave the ground. If it was simply a matter of producing pressure differences between the top and bottom of the wing, then how is going faster producing more lift??? Faster speeds will increase the flow of air on both the top AND bottom of the wing equally, right, thus not really affecting the delta in pressure. On the other hand, if it's as I point out above, speed is everything. The faster you're moving thru the air, the more air is being directed downward at any given point. This is why flaps and slats need to be used during landing and take-off. They force more air downward at slower speeds at the cost of much greater drag.

    the music should be louder
