Be interesting to know if Russia decided not to send fighters to intercept the MiGs due to not knowing what took out the Su-34s, or if the Russian pilots straight up refused to go. Understandable either way as anything that can reliably shoot down Su-34s can reliably shoot down anything in Russia's (or NATO's) inventory.
Wouldn't say that's true. The Su-34 is a good plane, not far behind the latest block F-16s or Typhoons, but those planes aren't the F-22, F-35 or Su-57 when it comes to entering contested airspace.
Seems odd that Ukraine would send MiG 29s to do bombing, but then I guess they felt their Su-25 would be MANPAD fodder and they couldn't risk using their Su-24s as they need them to launch storm shadows.
I think like a lot of things both sides have done in this war, it was probably done for morale or propaganda reasons. A bombing run by 1 or 2 MiG-29s isn't going to do very much on it's own.
