You're proposing that if something goes wrong on the ISS, the crew will need wikipedia to solve it? Not... talking to Houston or just taking the Soyuz back?

I wrote a crap SDR basically just from wikipedia, maybe their radio broke.

Presumably you have seen a science fiction film before, use your imagination.

> The next Apollo 13 will probably be a software problem , doesn't hurt if they can read up about it

What good would an "offline backup of Wikipedia" do in that situation?

Wikipedia is good for one thing, and one thing only: getting some cursory knowledge on a topic you're unfamiliar with. It's the tourist map to the "sum of all human knowledge." If you expect to use it for anything else, you're asking too much of it.

I have found a lot of the math articles to be quite good.

So, stackoverflow, not wikipedia, then?
