I was able to geolocate the target at 50°17'28.6''N, 36°56'30.3''E, it's an engineering factory. So, the attacking aircraft was within sight of the town. Why is that remarkable? Well, Volchansk is only a few kilometres off the Russian border, and less than 40 kilometres from the centre of Belgorod (where parts of the Russian 108th Anti-Aircraft Missile Regiment should be stationed). It begs the question why the Ukrainians were able to conduct these attacks unimpeded within sight of a highly endangered Russian metropolis.
The constant failures of Russia's air defences have puzzled me for a long time. They can't be explained merely by attrition. Maybe the rumours are true that Putin withdrew most air defence units to Moscow and Saint Petersburg.
