Like the tunnel network china and europe has that there's many all over africa though although im getting some countries dont have any that part of a goverment of military cause there 100% ran by offworld groups or groups that we just have no public knlowedge of like anicent cilivzations that evolved here or in our solar system b4 we did! or galaxy other dimensions etc
i noticed human apparently have airplanes that are 100% invisible to radar to addition to optical
cause ive seen planes and helicopters that dont show up on here or sometimes ill go on here to look then the seem to know i did and vanish moments after my eyes see them so i dont get a chance to do a picture screencap i guess?
funny some military installations you can according to human law legally fly over like fort polk,Louisiana
also many if not all major national parks/forests owed by the goverment have secret hidden entrances to the underground tunnel/base networks
