Looks like the skylon project is going forward and might have a working spaceplane flying around 2020
BBC news article
Skylon concept page
highlights from the info i have found so far:
the craft will be a ssto vehicle
it will use the air breathing sabre engine for it's ascent to orbit.
projected cargo capacity is about 12 tons to LEO
it is designed to be fully reusable up to 200 flights between refurb and rebuild.
also. it will use active cooling during reentry.
somehow i get the feeling that 200 flights between engine refurb might be a tad optimistic. but i could be wrong.
what i do wonder the most about tho is the use of active cooling during reentry. has that ever been done before?
what do you guys think of the progress of these kinds of vehicles so far?
oh yeah. i didnt want to open up the old dead thread about air breathing rocket engines. Esp. since it's in the wrong place imho. So
