"Q: Why would Russia fly into Turkey's airspace in the first place?
"A:There are a few possible reasons.
"First is pilot error. They were operating near the border and so strayed over by mistake. It's unlikely, given modern avionics, but nonetheless we can't completely exclude the possibility.
"The second thing is that this could, since Turkey is a NATO state, have been Russia just trying to flex its political-diplomatic muscles. Wanting to make the point that they can do this with impunity — which, of course, they have done in NATO's northern reaches." . . .
