nasa disagrees with you on that, or did you not comprehend what your links say.

{The upper flow is faster and from Bernoulli's equation the pressure is lower. The difference in pressure across the airfoil produces the lift.} As we have seen in Experiment #1, this part of the theory is correct. In fact, this theory is very appealing because many parts of the theory are correct. In our discussions on pressure-area integration to determine the force on a body immersed in a fluid, we mentioned that if we know the velocity, we can obtain the pressure and determine the force. The problem with the "Equal Transit" theory is that it attempts to provide us with the velocity based on a non-physical assumption as discussed above.

ps. it's site; not blind sight

additional reading for people; yes it's wiki

i got my airtabs, but then again my jeep is about as sheer as semi-trailers rear(62x68 inches of vacuum)
