Best of all worlds - .012 titanium and 1/8 fiberfrax. Hard to find,

something like 5000 degrees to light it, and you're not going to get
that in an engine fire.

My father in law once set a piece of titanium on fire that he was
machining in a lathe.

An entire B-one A burned to the ground here on the desert.
