My favorite comment on this was a blacksmith heating a steel bar to a few hundred degrees and then pushing it around with his pinky. Also, the sheer number of people who don't have any conception of what a blast furnace is or how it works, how oxygen and fire interact. Idk, I always thought the "jet fuel can't melt steel beams" thing was absurd on it's face. It's such a silly premise. I've forged metal on backyard wood fires, you just need to set the airflow up to get incredibly hot fires.
