It lookS aluminum, not billet but forged. I don't think we are seeing melted areas, rather shattered areas. I would say plane as well but there would
be some sort of record of a plane that went missing unless it were flying illegally. Perhaps drug running? Will be interesting to see what comes of
this. I think we can all safely say it is terrestrial.
I was just getting ready to post a similar thought and then I saw you had covered it. I definitely think it is a cast aluminum probably AZ92-t6
(Primarily an Aluminum/Zinc/Magnesium mix and I think a little silica though not positive ) or similar. Cast aluminum is rarely shiny due to the
almost immediate exothermic process of oxidation (Aluminum Oxide) forming as soon as it reaches the air after casting. It only takes about 2-4 hours
of exposure to oxygen/air to reach a thickness of about 4nm. I cast and machine metals as one of my hobbies and these look like aluminum.
The thick webbing used throughout the panels for strength and to reduce weight also look cast not machined. The holes in the various places look like
some sort of shrapnel hit the casting and broke chunks out. Castings are somewhat brittle so it would not surprise me that these holes are there.
Now what made the holes? Could be a jet impeller failure I suppose but I do not think so given that they are typically designed to fail in a somewhat
controlled manner and there is a sort of scatter shield or caging around it to contain such a mishap, not that it is 100% effective.
I do not think the holes were caused by heat as aluminum casting and billet when you melt them, the aluminum actually bubbles up under the layer of
oxidation which acts as a skin typically leaving you with a blister like appearance when the affected area cools.
I will have to wait and see what the professionals handling this can come up with.
