That was all Pilot error. Then he ejected to save his own butt. He should have known that the Flanker could not have recovered from that.
It doesn't even look like the burners were lit. Flankers smoke unless they are in burner.
As for fake, I think not. The reason everything is blurred except the plane is because the photographer was panning the shot on the plane. Follow the moving object and then everything else will be out of focus.
