F'ing freezing cold fuel tanks...

Hi All

The personnel to LEO problem wouldn't have quite so many dangers or hassles if it used something other than extreme cryogens like hydrogen. I know it packs a big wallop, but the stuff is expensive, cold and over fancy for the job.

Surely SpaceDev's hybrids would be safer, or the proposed SRB crew-launcher.
