The link you provided does not support what you are saying. The link you provided actually agrees with me saying that the theory about air being deflected down is correct. It merely says that while correct, this explanation is not rigorous enough to do engineering. Which is totally right. But I was not trying to do any engineering, I was trying to provide a simple explanation about how a wing works and how that relates to Newton's third law of motion.
