Thank you for this article!
Quite Interesting!

I came across this when answering a question on the underground, tunnels and mining.
I used to live in a town with a vast underground and national laboratory where the atomic bomb was built so have done numerous article and reports.

I have included it in two of my articles I wrote 5 years ago too, just as this one was done back then.
