The heatshield is not quite Avcoat. It is missing the crucial honeycomb that gives it structural integrity. I worked on EFT-1. It's test flight was gorgeous (2014). LM decided to remove the honeycomb. It is like a beehive with no honeycomb.
I changed projects bc it was obvious to that the risk was substantial, long befor Artemis was called Artemis, people said this.
