Actuali its sound like "Ooo nieeet opiat primery delaesh, Aaaarrghh" or something close to it unfortunately due to the fact that i have to listen to it non stop while flying for me its sound more like "please kill me, i dont want to live anymore, pls fly steady so the enemy pilot could kill me easily"
Its extremly anoing and make want to kill Boris or at best case hurt him very very bad
and its a little pity cuz i like fly IL2
and if i am right for some reason only IL's have this anoing dude
