How to build your own multistage payload rockets 70s style
Just in case you ever go into the underground and need to defend yourself from evil governments there is nothing like launching a satellite into space orbit. For that you need a rocket capable carrying a payload - how to build just that is explained in a 1971 manual about rocketbuilding. I would think papers like that will be worth quite much as soon as the "democratic governments" of the world consider the net a world threat and censor it out of existence - so grab it while its hot - you never know if you might need to launch that precious satellite into orbit for the survival of sane mankind.
