Spacecraft's pocket guide
So you want to be an astronaut? Then this might be useful for you: Ariane 5 User's Manual.
Ariane 5 is the ESA's (European Space Agency) most advanced launcher, until 2007 at least when Vega is planned to make its first launch, and is also the launcher that can put the highest payload in orbit, 6 tonnes.
~ I suppose it's not the only user manual as my car's one has almost the same amount of pages.
