Last night Copenhagen Suborbitals put up a blog post (http://ing.dk/artikel/124393-mangelfulde-wikipedia-artikler - in Danish) mentioning that there was a lot of factual mistakes in their wikipedia article, and that morally they couldn't support editing the article themselves. They provided examples of the inaccuracies in the blogpost.

It's now up to an independent third-party to edit the wikipedia page to make it correct.

The pge is here: http://en.wikipedia.org/wiki/Copenhagen_Suborbitals

I think that's a pretty good way of doing it.
