No wonder the Russians are losing. Ukraine started with about 200 airplanes in their air force. But somehow according to you the Russians have shot down or destroyed 590 of them.
And the Ukrainians are still flying around in some of those - 390 air craft. Time for you to concede defeat, you can't fight against a negative airplane.
Of those, about 380 are UAVs. For fixed-wing jets, your number of 200 flyable before the war sounds about right. I don’t think a lot are flying now, at first week about a dozen were shot down every day, now none to three max.
