Well, in the start of the war, there was a Ukrainian pilot that was giving the Russian airforce a pretty big nightmare, Ukrainians called him the ghost of Kyiv. He was operating a Mig-29 and successfully shot down 6 Russian jeta, that consisted of SU-57s. But he has been shot down like i believe a year or two ago. Which now the only worry for Russian pilots are the patriot system. But its still surprising how the Russian army was fumbling in the start, now the tide of the war is going on their side now, with most of the Russian campaigns have been succeeding. Im not trying to argue with you or anything, but its just that sometimes, not many things can always go a countries way. Now it going towards Russia's way, but we never know what the future holds.
