Radon in its solid/liquid form (-71°C) is where it's nicely glowing
with a bright phosphorescence from its own radioactivity, turning
yellow through orange to red as it is further cooled and/or compressed.
Thus radon can be compressed into an extremely dense liquid form,
obviously cooled by merely radiating the compressed heat into the near
vacuum of space (especially while cruising over the backside of Earth).
Then merely venting said extreme-frozen radon as need be, as a vapor
phase change (refrigerant) into becoming an extremely sub-frozen cloud
or worthy artificial atmospheric barrier of a gas that should react on
behalf of cooling the critical external surface areas of your
Spaceplane.

I like the notion of using extremely large surface area ceramic
air-breaks, as perhaps trailing edge fold-ups and fold-down flaps or
whatever formula of providing V-expanding surfaces. Then how about
plan-B of creating a disposable ceramic parachute, using that nifty CNT
fiber as the chute tether lines?

How about using a disposable composite ball of basalt, of an extremely
large enough sphere (artificial meteor) so that your Spaceplane could
just safely follow it in (perhaps as somewhat in-tow by a CNT tether)
as per getting safely through the upper atmosphere, then allowing the
remains of that disposable and relatively cheap Spaceball to land
directly on top of GW Bush and *** Cheney, as now you'd be killing off
more than those usual two birds with one stone.

I believe this could in a big and powerful way easily replaced with
those retro-radon-->ion thrusters as powered via the onboard Radium
reactor/radon generator (or He3 fusion if possible). The same
sub-frozen radon liquid could also be discharged for accomplishing the
necessary external surface cooling, or just evaporated within the hot
skin of the Spaceplane and then as a nicely warmed gas be fully
utilized as ion fuel, thus no wastage or other harmful discharges
whatsoever.

Learn more about Radon(Rn-222) before you become another GW Bush and
*** Cheney environmental fiasco partner in crimes against humanity by
using up our limited terrestrial energy resources and otherwise having
polluted by way of getting those other forms of conventional rocket
fuels safely created, stored, transported and delivered to your
Spaceplane, only to being 100% consumed and thus depositing their
remains for the rest of us to live with. Whereas Radon should not be
such a problem, as you'd be doing the environment and humanity a big
favor by getting that nasty Radium(Ra226) away from Earth, and then as
for the Rn222 as the Radon gas shouldn't be depositing anything but
harmless ions of perhaps polonium-214. Of whatever raw radon is
released (if any) upon reentry should be quite dispersed and/or nearly
dead by the time it reaches the ground, soon transforming into the form
of lead (which would have been here to start with anyway). What's worse
off; the radiation or the relatively small amounts of lead?

How much Spaceplane energy per tonnage (say per 200 metric tonnes
worth) for getting into LEO?

Kurt Vonnegut would have to agree; WAR is WAR, thus "in war there are
no rules" - In fact, war has been the very reason of having to deal
with the likes of others that haven't been playing by whatever rules,
such as GW Bush.
