Opinions on NASA lift theory?
That article appears to be a reasonable effort.
Doug McLean in his book, "Understanding Aerodynamics", spends 37 pages to describe the various means used to define lift, along with the shortcomings of most of them. These pages then finish with his thoughts on how to define lift. This highlights the sheer number of ways that his has been explained.
This book is quite good, but I only suggest it to a serious aerodynamicist.
