>>9909474Here you go anon, a whole lot on nazi UFOs and hollow earth
https://archive.4plebs.org/pol/thread/231626009As to how to get there, there are various cave systems around the world with weird tales of people going missing and reappearing in weird ways. For example the german untersberg has a lot of such myths around it, hitler took some interest in it and the dalai lhama called it the heart chakra of europe.
In the US the missing 411 could be linked to it.
Also there is some supposed map of such systems and entrances in the US, what is quite interesting is that the positions corelate heavily with the positions of cemex facilities. I would post it but im on phone and cant find it on here right now
