I have indeed purchased copies of Prouty's work and Leishman's textbook (including the answer set to the questions).

In the end it appears more and more that it’s a case of "teaching a new perception" in that many of the flight mechanics may seem obvious at first but are then revealed to be deceptively different. After such a revelation it’s almost impossible to "un-see" what was learned and obviously true.
I either case, I would like to extend an apology to those I may have offended with my first posts. I was perhaps too confident and the weight of that confidence was more than the critical yield limit of my knowledge base at the time.
