It's unusual to strap conventional explosives to an H-bomb. However, there's a quantity of an conventional explosive (TNT or something similar) in the bomb itself, working as "the ignition". This could generate a small crater, no bigger than a few meters in radius. The problem is, if this "ignition" explodes, the bomb will explode itself too.Per said:I wonder how much of a crater you get from an unexploded warhead? Unless there were some conventional explosives strapped to it (for that extra "boom")...
I can hardly wait to hear more about this, but my hunch tells me they screwed something up. Again.
