thanks all for comments and correction/suggestions.KL,
here I made a picture of the ground - changed contrast/brightness etc. to make surface details more evident:
- brown color represents area where grass/mud under the show could be,
- red color marks surface defects on the possible concrete,
Anyhow, it is difficult to say what is covered by snow and what is exposed.
Here is quite evident full snow coverage:
but what about this? Snow cleaned/removed from the concrete surface?
I am not sure about red spinner on the no. "15" and that next one. Board number and "white" outline of the board star is quite dark, significantly darker than tail marking. I do not know whether it is play of the light or they are dirty. And it looks like that only a front part of the spinner is repainted on those planes, similar to this:
The fact is that tail marking is very bright, looks like fresh painting. There could be originally white, now dirty/weathered spinners of "dark" white (i.e. no. "15") and freshly white repainted spinners (new plane and or spinner of originally different color, i.e. plane in the foreground).
Anyhow, red spinners would make color picture visually more attractive, but (front part of) spinners are brighter than red star on the fuselage.
"RS rockets are probably olive green or brown-green." Also at airforce.ru forum they suggest that rather than black they should be in "protective" (Zaschitny) paint color (AII-Z or 4BO or...?)
This is picture from airforce.ru:
Your suggestion for the caption looks good. I will replace it.
...the dark grey band on the back of the fuselage should be more likely green as from old Soviet templates...
should the right side of no."15" be only brown-green?
