This is fog of war stuff, but on Airframe recovery it ought to be relatively easy to establish from which direction the impact/explosion was, if it was shot down (most likely) and didn't just crash in a panic. They already know the aircraft heading... so probably don't even need to determine what it was hit with?

Hold the polonium sandwiches and novichok for now.
