The problem lies in your question. Dr.I 154/17 was dispatched to the air depot on December 13th and then estimated to take about two weeks before Jasta 11 would have flown it back to their airfield. There is no account on who flow 154/17.
Now if your talking about 454/17 in which Ltn.
Lothar von Richthofen did fly and crashed due to upper wing failure on March 13 1918, then we know that.
MIKHAIL BYKOV Fokker Dr.I 454/17
TODD COMEAU Fokker Dr.I 454/17
I just got Bob Preason illustrations that I'm working currently working on now.
I'm a little confused by your question be cause you
"Would the upper surface of this airfoil be in the green/brown streak, or would it have been red to match the rest of the undercarriage" the upper surface of the top wing has been suggested to have been yellow and the mid and lower wings were in the Fokker factory streaking. The undercarriage? are you referring to the bottom surfaces of the axle wing? The underside of the wings and fuselage were Fokker turquoise Methuen 22 B 3.5 (Alan D. Toelle) or Methuen 24A5 (Dan-San Abbott).
As far as I know there wasn't any red on the underside or undercarriage as you state it.
There are two people that have studied this plane a lot and they would be Greg Van Wyngarden and Dan-San Abbott. As the true color of the whole plane is 100% not known some of it may be up to interpretation.
In
Windsock-Von Richthofen's Flying Circus on page 52 Greg Van Wyngarden has 4 different photos from the crash site. So there are at lest 4 but there might be more.
