Titanium performed well and it didn't. It caught fire too, along with all
the aluminum. (the aluminum fire seems to be absent from the

What's interesting is that the titanium caught fire _before_ the
aluminum did based on the deposits on the recovered fragment of the top
window.

Yeah, it's interesting. It Burns like a piece of wood.

One of the other interesting failure was in some of the seat
structure, "broom-straw" fractures 3.1-16. Aluminum is a good conductor of
heat, but it also has a huge thermal expansion coefficient. I haven't seen
a "broom-straw" fracture before. Seems that Aluminum 7075 is a laminate
material.
