Hi again,
>Does anyone know more about the expert Rougeron mentioned in that article?
I visited the aviation museum in Hannover-Laatzen today and found in their museum shop an antiquarian book by Camille Rougeron et al., dating from the early 1960s.
It seems to strike a good balance between introductory text and overview of the state-of-the-art of the time, providing insights into design considerations that are skipped by most books.
Anyway, if you feed google Camille Rougeron's full name, you'll find some stuff on him.
He was in fact an advocate of the high-speed bomber, and had published his thoughts on air warfare in a book called "L´Aviation de Bombardement" in 1937. Apparently, he pointed out the vulnerability of reservoir dams to air attack in that book, so I wonder if he provided the inspiration for the British dambuster raids. According to Helmuth Euler, he definitely provided the inspiration for the German air defense of the dams.
Have a look at this document:

The text is in German, but the (peacetime) aerial photographs of the dams with the attack paths sketched in are quite interesting.
