I love that video of the guy showing closeups of it and showing that it's riveted, hollow, not magnetic. I saw that and went "Yup, it's aluminium."
Kinda makes me feel like Simon from Firefly looking at the "alien" in the freakshow and going "Yup, it's a cow fetus."
Honestly, I would like to see something like this as a message from aliens but I just don't see it happening.
