Had an interesting thought regarding the 4chan whistleblower underwater facility. Considering the claims of the whistleblower along side Grusch (big craft, even bigger inside <Indonesia I believe, sorry I forget the full story at the moment>). It had me wondering if the under water facility could be the same deal. There could be an entire planet in that thing. Vast cities, mountains, forests, etc.
On a side note – I’ve always looked up wondering about aliens, and thought it quite comical that they could very well be hiding under the blankets of the ocean. How clever.
