So NASA, a space organisation established in 1958 that readily offers tours of its fascilities and performs public rocket launches, is at the heart of a conspiracy to keep secret from the public an earth encompasing ring of ice. The motives behind this conspiracy are not certain, but NASA, who has for some reason been allowed to exist all around the world, will kill anyone who gets near the ice wall or reveals themselves to be part of the conspiracy. The public, seemingly blind to the disappearance of those who have been killed by NASA, does not question why NASA, who has, by law, public financial records, purchases weapons and other materials for its guards. Apparently, prior to 1958, no one has ever tried to find this ice wall, nor record its exsistense.
Seems a little fishy to me.
