Published in 1944, Stick and Rudder[0] by Wolfgang Langeweische has this to say:
>Forget Bernoulli's Theorem
>When you studied theory of flight in ground school, you were probably taught a good deal of fancy stuff concerning an airplane's wing and just how it creates lift. As a practical pilot you may forget much of it. Perhaps you remember Bernoulli's Theorem: how the air, in shooting around the long way over the top of the wing, has to speed up, and how in speeding up it drops some of its pressure, and how it hence exerts a suction on the top surface of the wing. Forget it. In the first place, Bernoulli's Theorem does not really explain- the explanation is more puzzling than the puzzle! In the second place, Bernoulli's Theorem doesn't help you in the least bit in flying. While it is no doubt true, it usually merely serves to obscure to the pilot certain simpler, much more important, much more helpful facts.
>The main fact of all heavier-than-air flight is this: the wing keeps the airplane up by pushing the air down.
>It shoves the air down with its bottom surface, and it pulls the air down with its top surface... In exerting a downward force upon the air, the wing receives an upward counterforce- by the same principle, known as Newton's law of action and reaction, which makes a gun recoil as it shoves a bullet out forward...
>Say that the wing is basically simply a plane, set at a slight inclination so as to wash the air down... But it was early found that the drag, lifting, and stalling characteristics of such an inclined plane can be improved by surrounding it with a curving, streamlined housing [emphasis mine]; hence our present wing "sections". The actual wing of an airplane is therefore not simply an inclined plane; it is a curved body containing an inclined plane.
