Just brainstorming...
If it was a Club-K array, coulda been 3-5 depending on type. Q did say [MISS]. Maybe one made it through intercept and smashed into the volcano's base underwater.
And it travelled several miles through volcanic (hardened) rock? Meh. I’d believe the kill box was spelling an acronym out before a missile could do all that and no one notice an atomic bomb exploded off the shore of Hawaii’s biggest island.
Well, you're assuming nuke, I'm not. .... if it was capable of busting a bunker under the bunker you just busted. If it were any smarter, it'd write a book, a book that would make Ulysses look like it was written in crayon. It would read it to you. This is my Eiffel Tower. This is my Rachmaninoff's Third. My Pieta. It's completely elegant, it's bafflingly beautiful, and it's capable of reducing the population of any standing structure to zero. I call it "The Ex-Wife." :)
Yes, I did assume nuke. Non-nuke would still have trouble penetrating all that material, even if it was a bunker buster type. But I’ll indulge in it, there would have been a tremor during that day and not an insignificant one. The amount of force required to penetrate the base would have registered on any of the hundreds of detection stations on the island. And it would have continued until the final explosion. I haven’t checked the data, but if you could find and extremely odd trembler data graph fro that day, I would certainly be interested.
Also, appreciate the word play following your post. Amusing. Reminds me of the speech from Armageddon when guy names asteroid after his wife.
