Yeah that molten metal thing got me too after watching some docs. First responders talking about pools of it weeks later just doesn't fit the official story at all. Hearing it from the guys who were actually down there makes it impossible to ignore. That detail alone flipped a switch for me.
My uncle worked salvage in the 90s and said they'd find weird stuff in old factory fires... like metal that had dripped down and hardened into these strange shapes. Always stuck with me how heat can do unexpected things.
