It's not clear this is the case. Heat is being transmitted from
the RCC to the wing structure by radiation. Interposing an opaque
material (for example, carbon aerogel) could actually reduce this.

The heat is going to go *somewhere*. So the question is, how does the
RCC stand up to a prolonged heat pulse, from the front *and* the back?


Why should it need to go anywhere? Where does the heat at the
surface of a tile go? If the RCC is stable and structurally
sound at the maximum temperature it's expected to experience,
why not insulate behind it? It can't get any hotter, can it?
I only ask because I truly don't know the answers to these
questions.
