Hi all,
Langdon,
1.
"On the 24th, 105 sorties and involvement in fifteen air fights produced a loss and a victory. The day's sole victory - 
Manfred von Richthofen's 67th - was scored... Richthofen, looking like the apparition of red death in his first combat in the all-red Fokker Dr.I 477/17, ..."
Kilduff cites, not for the coloring of 477/17, but for the combat report that followed;
"Note #37 Public Record Office, op.cit., p.38; Ibid., p.74; S.E.5a C1054, Lt. J.P. McCone (Mia)."
2.
"[26 March] Ltn.d.Res Ernst Udet reported for duty at Awoingt... It was Udet's first flight in a Fokker Dr.I,... He hung back with the others as Richthofen dived down in his blood-red triplane to seal his 69th victory."
Kilduff cites, not for this paragraph, but for an above paragraph which is from Udet's "diary", so as this paragraph follows the above, it may be from the same source.
"Note #39 Udet, op.cit., p.67"
Kilduff cites many sources throughout his book, almost every other paragraph, with good original source material, such as Public Records, RFC Communiques, Bodenschatz, and many other pilots works.
No smoking gun found here, although if this is Udet's direct observation, then he would have made it the afternoon before they went to Lechelle, and that would be good testimony.
I'll have to look up my Udet's
Mein Fliegerleben, (if that's the book Kilduff is talking about).
Best,
Dave W.
