Which makes me wonder if this was a Ukrainian drone at all. False flag operation, complete with "fortuitous" video, would be in character for Putin's Moscow. Lots of western news coverage and lots of screeching from the fellow travelers on social media. (And of course FR.) Win-win for Putin.
The real issue is, why is such a trivial event being reported at all by propaganda press in the West? Civilians are killed almost every day by deliberate Ukrainian shelling targeting them in Donetsk and other Russian-held areas. This is regularly reported in Russian and international (non-western) media. I surmise that reports like this are meant to distort western populations' perceptions, into believing their own press is fairly reporting attacks on Russia when in fact it is not.
