Ha ha Touche!
Sorry long day at the office... You're absolutley correct. Was trying to make the point about CAA aerodynamics and theory and the real world! Not unlike CAA paperwork and the real world.
Kutta-Joukowski subscribed to the principles of conservation of momentum and newtons 3rd law. As such downwash from their rotating cylinder resulted in an opposing force pushing it skyward. This still doesn't explain flat plate sufficently. A good explanation is here:

To be honest i'm digging deep here so i'll have a think and see what I can come up with!
