My physics is far enough in the past that I'm probably
going to screw this up (I'm sure Dan is going to
correct me) but this doesn't seem all that remarkable,
and I think he's completely misunderstanding what's
happening.  You can heat (for example) the thermal
protective tiles on the shuttle to thousands of
degrees and then touch them with your bare hand, as I
recall, because they absorb the heat and then _fail_
to radiate it, not because they cool immediately. 
It's the difference between sticking your hand in an
oven at 400 degrees (safe, because the air will not
transfer heat to your hand fast enough to burn it) and
touching the metal _in_ the oven (not safe).  The
_temperature_ of the two substances is the same, it's
the energy transfer that's different.  Isn't that all
that's happening here?
