The original invite was to pop over to Norway for a few days to see the RN doing things with autonomous watercraft (boats and mini submarines). Part tech demo to show off British industry, part "oi, Vlad, we've got toys that can detect your toys now". Unfortunately the timing clashed with something else.
Sportingly, the RN said "come aboard anyway". Hence I got to treat you all to tales from the Arctic, as well as discovering Windows ME/XP and Apple Macintosh still in use.
