Its dramatic collapse several hours after the Twin Towers fell triggered a decade of conspiracy theories. Those who believed that the September 11 attacks on America were not carried out by Al Qaeda terrorists pointed to the fall of World Trade Center Building 7 as proof of their wild claims. But a newly released video appears to finally prove once and for all that Building 7 was brought down by the intense heat of the blazing World Trade Center - and not explosives, as conspiracy theorists claim.

Actually what people don’t really get is that the steel never had to melt. It only had to reach the softening point which is a lot lower temperature than the melting point. The truth is that jet fuel will not get you to the melting point without some work. However it won’t have any trouble getting to the softening point. Once you hit that the structural members are more like silly putty than I beams.
I once had this discussion with a wingnut who believed it was an inside job. The fact that I have a PhD in steelmaking didn’t seem to phase him at all.
Silly man. It was the Jooooos! /s
“Fire doesn’t melt steel, right?”
No. And if that makes you wonder what people do at steel mills all day, well, they melt it with the power of love.
Ping a ling
The fact that you have a PhD in steelmaking proves the point!! What’s the frequency, Kenneth??

My favorite “proof” that “fire doesn’t melt steel” uttered by a former neighbor, an English teacher.
“Look, I’ve been cooking on this stainless still grill forever and it has melted yet and neither has the lid. I’ve got a Master’s degree you know.” She said with a sneer.
Rosie the Riviter worked with steel all the time. She should know.
“I loved the History Channel program that reviewed and debunked the conspiracy theories.”
Apparently, they’ve matured since airing “The Men Who Killed Kennedy.”
I knew that. I was adding to the sarcasm by pointing out that fire is the primary means by which we have always melted steel. Weather by accident or intention. The engineering curriculum being my evidence.
I guess I failed.
iBeams - something else Apple will trademark. lol
According to them Bush was the most incompetent President ever. And yet he supposedly planned and orchestrated the most complicated and largest controlled demolition in history.
...just like the Mars landing too, which is why we had to frame OJ.
“Look, I’ve been cooking on this stainless still grill forever and it has melted yet and neither has the lid”
Was her grill propping up a skyscraper?
Also why the approximate hour wait after the planes impact the towers before blowing up the buildings? Did the evil conspirators have some compassion to allow a number to escape with their lives first before saying ok they’ve had enough time bring the towers down? Wouldn’t evil conspirators want as high a body count as possible to stoke outrage?
They vacated Building 7.
They vacated it for a reason, It might go down , It did. End of story.
My mechanical engineering curriculum didn’t cover the non-fire technology for melting steel.

The EE’s cover it.
IIRC, the WTC towers employed an innovative construction technique. I do not recall the details, but it relied on steel cables in tension, something like a suspension bridge. Once the heat caused the cables to go into yeild (get soft), the whole thing collapsed like a house of cards. It had a considerable amount of redundancy, but more support was lost on the side of building towards the entrance wound, unbalancing the contraption and reducing the margin.
lol
I always wanted to asked Rosie if she thought steel gets dug out of the ground in that shape or if they grow them that way.
