From my understanding any flying that happens is just to get jets up in the air to shoot long range missiles, and then they go right back before getting within AD range. There’s also very few left as we’re seeing. The long range missiles the west is feeding are definitely having some impact, but the context is that Russia is using an order of magnitude more missiles and drones pretty much on daily basis. If that’s what wins the war then Russia is winning.

I think ultimately what this comes down to is that it is a war of attrition, and Ukraine can’t sustain this for much longer because the west simply doesn’t have the industrial capacity to keep it going. The only question is how long before Ukraine finally understands this.
