Thanks, I'll look for both of those. I've got a copy of Fighter by Len Deighton, and it not only has interesting photos (few messerchmidt, sadly)but also some interesting caricatures of Erhard Milch, Hugo Sperrle and Albert Kesselring made by Ernst Udet before his death. Until I got the book, I had no idea they existed.
EDIT: The first book is right here at the library, and I found another one in the series of the second book that concerns Kurt Tank.
