As a lifetime Target shooter, I commend the tight grouping on those 2 impact points. I agree that the underground BDA is impossible, but I can imagine that 3 successive deliveries of a MOP at fairly short intervals [my assumption] is likely to have caused some substantial disruption … especially where the centrifuges are concerned.
I’m intrigued by the selection of those 2 impact points, which suggests ‘someone’ had a good idea of what lay buried under the terrain.
