RE: BUSA Fokker DVII
stall,
The controversy over "red or black" on the Udet color scheme seems to be never ending and is consistently being rehashed by people who have little better to do.
Photographic evidence is inconclusive and all in black-and-white. When red is photographed in B&W it turns out black anyway. As I remember from my reading, this particular aircraft was shot down, so there is no extant physical evidence. Eyewitnesses would be closing in on being centenarians, even if they were children at the time.
Bottom line: If you're doing this scheme, use either color. Nobody can prove you wrong.
