It was a thoroughly planned ambush; they knew perfectly what they were doing; for more than an hour (that day only) they waited in the air for an optimal moment to hit and hide.
One of the fuckers' commanders was later recognized as a Grey Wolves (Turkish Nazi movement) member and Turkish citizen Alparslan Çelik.
Our war ministry announced yesterday (link above):
As soon as Captain Murakhtin [flight navigator of the downed plane] was safe, massive airstrikes were made by Russian aircraft and the Syrian rocket artillery on the area occupied by terrorists who had been actively searching for him.I hope they all did not survive the killed pilot for long, and their death was painful enough.
The only question that remains is
why does a NATO member fight for ISIS?
PS: As for now, Turkey received a great publicity; I don't know what Erdogan thinks (and I don't give a shit about that, frankly speaking), but I doubt the Turks wanted it that way.
