Aerodynamics, is for the most part an experimental art, and it is an art, as so many technical field's really are...
Isn't that the truth.
It always makes me smile when people get adamant about Newton in discussing where lift comes from. They seem to totally ignore the fact that wind tunnels have been around for quite a while and in those it is easy to measure the actual pressure at the wing surface on both the top and the underside.
I was brought up to believe that to be correct a theory had to fit in with the facts. Hey ho.
