This sounds interesting!
""...all it was they saw a flight of Fok.D.VII led by an all white Fok.D.VII with red crosses, the other guy said "what looked like red crosses"...""
Dan-San, I really believe that the allied pilots reported the "red crosses" but this raises another question:
The crosses on the white aircraft would have been those of the "late style" Balkenkreuz with the thin arms. Additionally I think it is not very easy to differ between red and black in the case that it is not a very bright or shining red. The American pilots would have been extremely close (less than 200 or 150 m?) to identify that so clearly. And if they were so close, why did they not engage the enemy (they were from a pursuit squadron) or why were they not sighted and attacked by the experienced pilots of the Jasta?
Additionally I have some doubts if Göring would ever have got the permission to use these "uncommon" national markings. His superiors surely would have stopped that pretty soon.
Is it possible that the "red cross reports" were made for propaganda purposes?
Just some questions?
