(Retro) Space Race era Rapture ... The moon Rapture would have been a simpler environment to build on (and alot underground and less pressure differential - like a factor of 20), except for the transportation issue (launch to Earth orbit and a quarter of a million miles to travel). Ryan had long term plans of building a Rapture on the Moon, and started work using 'borrowed' German technology. Forget Columbia. Have something spiffy like this for traversing between sections of Ryan's Moon Base Even More likely these for the Space Race Rapture - we gots Rockets so we also gets Rayguns ... --- --- ---
