RL interfered unfortunately] I'm not sure if it is of any use or interest but one of my 'nice to haves' would be a Land Speed Record car or cars. Would a 'rough' model of Thrust SSC be a reasonable starting point for the transition from aircraft to car? It would at least allow you to put off adding driven wheels for a while. Just a thought, I'll go back to hiding now. Before I do, does anyone want me to repost the URLs on the official standards for runways markings in the US, UK and Australia I dug up a while ago? They also outline the 'new' standard that the US will be / is transitioning to.
