Some type of plastic mixture for fuel? Didn't know that was a thing

Nah its nitrous oxide and roofing tar, I think they were using synthetic rubber with ammonium perchlorate which is similar but normaly less volital than asphalt tar, you cast and engin with a hollow column down the middle and they spray the Nitros Oxide down the empty center space, and boom! I know some guys in huntsville use to shoot civilian rockets up to 30k feet often using that fuel from a barge down in the gulf.

It wasn't in space. The mothership had just dropped it off. Rocket lit and instead of being a rocket it was a bomb. Survivor punched out. Probably injured by debris field.
Oddly this type motor had blown up in test fires. One explosion killed a couple engineers. Then a few other test had problems too.
IN my opinion the rocket obviously needed further testing. This was the first virgin flight with this new type of solid rocket.
