Not really a pro Pilot but I do fly recreationally as a Private Pilot....But didn't the Russian misgauge the distance between him and the drone badly? He wanted to dump fuel on top of that MQ-9 (for whatever reason I don't think that would do much) so he should have fly over and forward but seems like he hit the aft and up.
I don't think he is that stupid to risk his own craft and ram an unmanned vehicle, nobody is that stupid so we can pretty much ruled out he was doing this (the crashing, not the fuel dumping) on purpose.
