Dead pilots have always been slumped forwards in my IL2 with or without gore =1
But Gore =1 "Blood in pits" only works in Russian .exe not the European/US versions, unless you are using a Modified/hacked version.
Re the He 111 tail MG17, I've never seen 100% documentation to show who actually fired it, although I am leaning towards it being able to operated injunction with the top gunner and or separately by another crew member.
Will be interesting to see if anything comes to light here.
