Phoenix - a complete history of the luftwaffe 1918-1945. Volume 1

[taitbb]

I haven't picked up this book...so am more looking for thoughts on if this book still has any value/use even with its flaws.

First, is there any other comparable modern English language work that delves into this early history with as much detail.

As we all know the vast majority of early luftwaffe documentation is lost. Is there even much official documentation that could have been referenced? Is outdated books from Nowarra sort of all that exists? Even if collected from imperfect memories?

I am asking as still being a potential buyer...as this is an area I have almost no literature on.
