By another you mean this one I suppose?
That is from days ago, there is a new shot down of a Su-35/Su-30 recently
The Ukrainians assure that they have shot it down, while some Russian sources speak of friendly fire... In any case, both options spell disaster for the Russians, who just a few days ago lost an Su-34... Two of its most modern combat aircraft shot down in less than a week
We just hope that the Russian MoD doesn't come out that shooting down their own planes is a "goodwill gesture"...
