Do you mean Vikings as in raiding & trading marauders, which probably belongs in some fantasy subforum (space opera), or just Scandinavian space programs?
Not sure how to achieve the first unless space really is more like the ocean than science seems to indicate it is.
Yeah, I mean the raiding & trading marauder Vikings.
Basically, the challenge is to have the Vikings establish a permanent nation/empire, survive to the present day, and then send a man into space in the 20th Century.![]()
