Sure, we are seeing planes flying over Kiev everyday because it is so obvious that the RF has control of the sky... Maybe you are mistaking the HARM radar seeking missile that has been very much used to kill RF radars all over. Nothing to worry, the Ukrainian air defence is not doing anything, the Ukrainian troops are just playing chees in the trenches waiting to be killed. Nothing to fear, nothing on the build.
Hint: try that you propaganda at least matches to a point reality. If not, even those who really want to believe it, will not be able to.
The likely reason that you are seeing no RF aircraft flying over the city of Kiev is that the Russians have no more reason to fly over it than I do. That would be zero.
