This is also there. The Denver airport complex is much more than just an airport. There’s a lot of indications, IMO, that it’s on top of a giant underground military installation. Some rumor it’s a backup DC/Capitol that’s on the other side of the Mississippi. Colorado has tons of military and arms manufacturers there with very large underground facilities in the mountains. Protects against nuclear strikes and the deeper you go helps protect against being scanned by certain types of EM radars/signals for 3d mapping.
