Skylon is actually really impressive, easily the best non-nuclear SSTO concept of all time. Could get a legit load of cargo to the space station, and that atmospheric oxygen condenser system is really impressive-gulping up to mach 5 air, ripping out the oxygen and chilling it down for later rocket use in a fraction of a second is pure witchcraft.

Imagine a passenger variant for space tourism/LEO application. That would be sick.
