Kutta-Zhukovsky-Prandtl Devoid of Physics

David Auerbach starts out in Why Aircraft Fly by:
  • The question as to the origin of lift is older than Newton who, himself, gave the wrong answer (see, for example, Toakaty [1]). The vortex theory of flight due to Zhukowsky [2], Kutta [3], Lanchester [4] and Prandtl [5], although doubted by few, appears to many so devoid of any direct experiential basis that there are constant attempts to understand why an aircraft really manages to remain aloft: the idea of a bound vortex with its circulation seems so passive, the explanation, so abstruse and complicated.
Read and contemplate! These are tough words about the Old Theory of Flight of Kutta-Zhukovsky-Prandtl. Are they true?
