This is apparently a plot of the Russian aircraft (in red) just cutting the very tip of Turkish airspace (to the north) as it was shot down. If this is a true image of what happened, then Turkey looks as if it is being highly unreasonable and irresponsible, as I said previously.
If this was Turkey shooting at a Syrian aircraft I would say it was deliberate provocation. But prodding the Russian bear for no good reason is bordering on the insane.
I see that popcorn futures are rising again....
