Its was the last Hurrah of a DARPA research project.  Now they need to go take another look at the thermal protection system they used, or, get Brett Buck to redesign the vehicle  :!

  Not likely with all that air around. It would be ablative, however. For about 2 seconds.

I made ablative chambers out of several different materials in several configurations for "rocketdyne" in the early 60s " mercury" and "Gemini" space capsules. from about 3" in dia. to about 18"s  Jim
