On a more serious note, the folks who design and build gliders probably
have a good idea of what creates lift.Â* Why not ask them? Or do you
suppose that they know "how" but not necessarily "why"?

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.
