[@So Boerd] https://www.youtube.com/watch?v=4Ugebzq3juE I appreciate the maths you have done because I love me some maths. Forcing aerial ships to go with the wind would be a rather interesting turn considering that Steamships have only just recently dethroned a need to obey the winds on the sea. Or maybe we're all just over thinking it and should consider the above link. I'm open for either route really. My inner scientist calls for the former, but my inner goofball calls for the later. In the end I throw it to the Proles to decide.
