Alright, we know that the junkers originally came from Gallia. I'm guessing this was before the minefeilds went up or while they were going up (when was this by the way?). Now my question is how did technology get transferred between the junkers in Sirius and Gallia? Were plans drawn up by the junkers or stolen and then transmitted to Gallia?
I am asking because I am working on some RP that involves people traveling between Gallia and Sirius after the minefields were put up. If this was not possible through uncharted JH's (which may have been used for the technology transfer) then how long would it take to travel between Languedoc and Orkney or Languedoc and Tau-23 in a survey ship that would have been used for long-distance space travel like this?
