Wrong is such a harsh word. Simplified is more like it. Once you talk about large ships and aircraft, there will be multiple engines, and patrol speed might mean feathering some of them. _______________________________________________ GurpsNet-L mailing list <[email protected]> http://mail.sjgames.com/mailman/listinfo/gurpsnet-l
