There is perhaps some intimation that my answer regarding German technology during the Third Reich may not be based upon research, which Mr. West intimates is very difficult.
As I am now approaching 70, my research concerning the relative state of the art actually began well over 50 years ago. Since that time, I have indeed performed a fair amount of research, most on my own time but also some paid for others. I do not find it particlarly difficult, but it does take time and effort and some knowledge of the subject matter to understand what one is looking at.
I have a somewhat unusual background, having degrees in both physics and history as well as being a registered professional engineer. I have also been a pilot for over 50 years having been fortunate to fly props, jets, gliders, helicopters, flying boats, etc. I also at times made my living doing research on what are known as WMDs, having been up close and personal with conventional, chemical and nuclear weapons. As to Luftwaffe related research, over the past 50 some years, I have been in several archives working both with original and microfilm copies of Luftwaffe related material from both sides. At a minimum, I have personally looked at 3 or 4 million pages of material. While I recognize this is not exhaustive (there is still a lot of material to look at) and I am just as prone to errors as the next person, my perspective as an aviation person, an engineer and a historian is hopefully not too bad.

Best regards
