A photostat and some descriptive instruction on the production of the Aerial Armada can be found here: http://billwerks.blogspot.com/2008/10/british-aeronef.html
It is likely that aeronefs and digs shall make an appearance in this journal in the next year or so.
Minor progress was made this weekend on some new structures to replace the Earth-style buildings used previously. I think that Earth buildings will be kept apart, perhaps in an Earther conclave or compound. Martian and Venusian architecture is going to be a bit different, and I hope interesting.
