Sounds like Karhila was officially credited with damaging three IL-2s but many years later he misremembered and thought it was five IL-2s. Of course the way to see how many he actually damaged and maybe if any of them crashed is to look at the Soviet records for the relevant air regiments on that day. Maybe some of those IL-2s actually crashed and he did better than he thought! However until that research is done his official claim of three damaged is the one that stands since his memories decades later are unreliable.I personally talked about this with Kyösti...he said he scored 5 but run out of ammo on the sixth Il-2. He was extremely happy someone had actually seen it happen and remembered it.
Does this somehow refresh your hostile and uneducated attitude towards this case...or are you just trying to pull my leg ? I don't fully understand your hostility towards men in uniform but your attitude needs correctional acts pretty soon.
