A topic related to the underground theme-

FEMA has around 25,000 underground nuclear-hardened bunkers that comprise the parallel US government infrastructure.

The USG's engineering firm that builds them, URS, also handled the clean-up/cover-up at the WTC and is building the 14 permanent bases in Iraq. URS is to the USG what bin Laden Construction is to the Saudis.

I'm inclined to think that woo-woo about what is underground is related to FEMA's projects rather like 'remote viewing' is related to satellite projects.
That is, a form of misdirection through exaggeration.

He said not a single multi-ton block had to be brought from
hundreds of miles away, as long theorized, because the blocks
were made right on the spot using wooden forms, just as
sidewalks, for example, are made today.

and now we know how that was done, which is kinda confirmatory?
