A brief note about that airliner over the Ukraine.
Most likely story. which we may never find out.
A bunch of rebel casuals gets their hands on the SAM kit their Russian friends had supplied them, for the purposes of shooting down Ukrainian government helicopters and troop planes.
Training was a little rushed, especially that bit about really checking the identity of the plane you were firing at.
But it wasn’t on an official flight path. Usually only troop planes here.
Airliner diverted to avoid turbulence/heavy weather.
Rebel commanders seriously pissed off with muppet who was only trying to score another troop plane.
We can blame the Ukrainian Government.
