Jet fuel doesn't melt steel beams. But metal loses it's strength while retaining its solid phase as it is heated. https://www.engineeringtoolbox.com/metal-temperature-strength-d_1353.html
This is the issue with laypeople speculating on complex engineering failures. The mechanisms of action that one might intuit from looking at a complex systems failure and the ones that actually cause it are oftentimes not related to or even opposite.
Does that link talk about the explosions in the basement?
Hey, you know the deal, no investigation, no right to speak. The link doesn't talk about 9/11 at all, it talks about changes in metal strength at different temperatures.
Ive never heard that turn of phrase, pwease explain it to me?
