Hi Leo
Well, since the microfilms clearly state a Hoffmann (no given name, which means no Hermann is named) from 11./JG 54 as making a claim against a Thunderbolt that day, it would have been very nice of the JFV team to add a footnote why they suddenly discard that information and what evidence they have that Rathenow all of a sudden made that claim.
There is otherwise no lack of footnotes in their books
Cheers
