Nudging back on track for a moment:
the "Luftwaffe War Diaries" give an interesting perspective, as does "Design For Flight - the Kurt Tank Story" by Heinz Conradis. Kurt Tank of course rose to be the head of the Focke-Wulf company.
There was an interesting incident in 1979 or 1980 during the BOB reception in the Rotunda of the British Embassy in Washington DC. We had invited some of the GAF folks over from their embassy, and the British ambassador at the time commented on the fact that they were there. The GAF colonel overheard the remark and said why shouldn't we be here? after all, you couldn't have done it without us. Which ended up with drinks all round.
