What this makes me think of, is the first WW. Then, sappers, many ex-miners from Wales, dug under no-man's land to lay explosive charges under the
Whilst the Allies were digging in one direction, the Germans were doing likewise in the opposite direction.
Sometimes the tunnels would meet and there would be a mini underground battle.
The idea purported by one poster, that there were many underground cities, and that maybe one city would fight another...well seems very likely,
that's if there are underground cities, of course.
I do ask one question, would there be a difference in the resultant crater, if, rather than the solid earth of the early tests, the explosion occurred
in the more open space of an underground city?
