even as its nothing about red star, its still incorrect to mix it up with (*) normandy stripes as the red ring on the fuselage did indicate that they are on the home-defending theatre over the reich; just as the yellow was the theater sign of the eastern front and white of the mediterranean. later on i saw combined ones, +green, blue 1s, all on late -44-45 aircraft also on hd assignment but i dont know anything abt thm.
(*: although i must say i wouldnt mention this on my own [hm… just felt i’d like to add after these ;P] as its not that important imo and the thing is fine nomatter what insignia is shown i think 
p.s. i played that game woot!!!
still having the screenshots from the me 262’s engine and cockpit made in the hangar ^^
p.s.2.: now i rewatched the very nice video, they dont even seem p-51 mustangs to me but p-47 thunderbolts? =O
p.s.3.: oh crap; now watched frame by frame… they seemed p-40 xxxhawks? 
p.s.4.: which were not used in normandy… and hell yeah, both the shark mouth and the early us insignia on them [which i like more btw than the later with that ugly bar added and the red dot removed… shouldvbeen reverted after the war -.-] are indicating this (along with the under-forward section of the nose, shape of the wing and horizontal stblzrs on which i first based the guess)… and they werent used in normandy and never had those stripes xD! but just as i said earlier lets just keep it as it is, these little inaccuracies can be fun to have, can give some nice original/custom/personalized/unique/interesting look

Katyusha will be on the site eventualy, it just needs to be redone at some parts, the blueprints i had were wrong. Also, they should be all downloadable soon.
