Well, fire has never melted steel, right?

FACT: Jet fuel burns at 800° to 1500°F, not hot enough to melt steel (2750°F). However, experts agree that for the towers to collapse, their steel frames didn't need to melt, they just had to lose some of their structural strength—and that required exposure to much less heat. "I have never seen melted steel in a building fire," says retired New York deputy fire chief Vincent Dunn, author of The Collapse Of Burning Buildings: A Guide To Fireground Safety. "But I've seen a lot of twisted, warped, bent and sagging steel. What happens is that the steel tries to expand at both ends, but when it can no longer expand, it sags and the surrounding concrete cracks."
Right. Steel mills are a myth promulgated by right wingers to prepare the public to believe the lies later told about the 9/11 George W. Bush false flag operation. Blacksmiths never existed either. /s (Don’t worry, I know you were being sarcastic, too)
