This mesh is my own version of the SHADO Moon Hopper or 'Moon Mobile' from Gerry Andersons 1970's TV Series UFO.
It is intended to complement the SHADO Moon Base I built earlier in the year, so if you haven't already installed it you can get it here: http://www.orbithangar.com/searchid.php?ID=2941
To use this add-on you need to install Vinka's Spacecraft3.DLL: http://users.swing.be/vinka/
