Skylon looks like it could be made to work for about 4 billion, and the only totally new parts (heat exchanger and fuel-intercooler scheme) have been demonstrated working. It is mainly a better-designed HOTOL ( http://en.wikipedia.org/wiki/HOTOL ) which was described by the actual designer as "turned out to be an expensive way to send a hydraulic system to low earth orbit" I can't see anyone finding the 4 billion in the current climate though. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
