Actually, both models describe the same phenomenon. The Bernoulli
principle explains the detailed mechanics of lift, while the momentum
exchange model explains the end product physics of lift. After all, a
symmetric airfoil generates lift by angle of attack, as does the "flat
plate" airfoil, with zero camber.
