For the thousandth time.....
The conspiracy is probably the deviations from the best practices of using concrete cores and deviations from building codes.
It was documented the WTC fire insulation was substandard and needed up graded before 9/11. The insulation knocked down by the jet impacts did not help.
The towers had long floor trusses with no mid supports along their spand.
The jet fuel ran down the elevator shafts, causing the spread of fire at a rate and intensity the towers were not designed for.
The jet impacts took out or damaged outer columns and core columns causing the load to shifted to the vertical columns that still had structural integrity.
The jet impacts cut vital services, elevator cables, and fire water.
How would a complex detention system survive.m?
The fire heated up the steel.
The steel of the floor trusses weekend and tried to expand in length. The expanding floor trusses that were boxed in by good columns could not expand in length, so they droopped down. Upon cooling, the floor trusses contracted. Thus causing inward bowing leading to buckling of vertical columns in areas corresponding to the fires and jet impacts.

Once buckled, the falling upper stories of the towers overloaded and sheared the floor connections to vertical columns. Floors that could only withstand the dynamic load of six falling floors or less.
The floor system totally collapsed. But large lengths of core columns were left standing on end for whole seconds after the complete collapse of of the floor system.

I see a structurally damaged building that is beginning to collapse.

Yes, I have been called worse.
A shill and many other names.
I have personally done many hours of research on the towers. I have even went as far as to attempt to calculate the weight of each floor on my own. I have put countless hours in identifying the bolts size and shear strength that connect the trusses to the supporting beams amongst many other aspects of the buildings structure. I have also had numerous talks with my welding instructor while attending a two year welding technologies course.
I actually tend to get tired of the same old arguments and name calling antics that I usually end up giving the subject a rest for a while.
It is nice to see posters such as yourself using logic and looking beyond the ignorance that so many posters like to adhere to.
Keep up the intellectual fight.

I see a structurally damaged building that is beginning to collapse.
FDNY Assistant Chief Joseph Callan: "Approximately 40 minutes after I arrived in the lobby, I made a decision that the building was no longer safe. And that was based on the conditions in the lobby, large pieces of plaster falling, all the 20 foot high glass panels on the exterior of the lobby were breaking. There was obvious movement of the building, and that was the reason on the handy talky I gave the order for all Fire Department units to leave the north tower.
Callan: "For me to make the decision to take our firefighters out of the building with civilians still in it, that was very tough for me, but I did that because I did not think the building was safe any longer, and that was just prior to 9:30.
EMS Division Chief John Peruggia: "I was in a discussion with Mr. Rotanz and I believe it was a representative from the Department of Buildings, but I'm not sure. Some engineer type person, and several of us were huddled talking in the lobby and it was brought to my attention, it was believed that the structural damage that was suffered to the towers was quite significant and they were very confident that the building's stability was compromised and they felt that the north tower was in danger of a near imminent collapse.
I grabbed EMT Zarrillo, I advised him of that information. I told him he was to proceed immediately to the command post where Chief Ganci was located. Told him where it was across the street from number 1 World Trade Center. I told him "You see Chief Ganci and Chief Ganci only. Provide him with the information that the building integrity is severely compromised and they believe the building is in danger of imminent collapse." So, he left off in that direction."
Federal engineering investigators studying the destruction of the World Trade Center's twin towers on Sept. 11 said New York Police Department aviation units reported an inward bowing of the buildings' columns in the minutes before they collapsed, a signal they were about to fall.
"The NYPD aviation unit reported critical information about the pending collapse of the building,'' said Sivaraj Shyam- Sunder, who heads the institute, at a press briefing in New York. "Any time that information could have been communicated faster to the emergency responders in the buildings, it would have helped save lives."
According to Shyam-Sunder, the concave bowing of the steel was seen on the sides of the towers opposite where the planes hit them. At 10:06 a.m. that morning, an officer in a police helicopter reported that ``it's not going to take long before the north tower comes down.'' This was 20 minutes before it collapsed. In another radio transmission at 10:21 a.m., the officer said he saw buckling in the north tower's southern face, Shyam-Sunder said.

Do you know of any explosives that do not breach the sound barrier ?
If they do not breach the sound barrier they are not explosives.
If they do breach the sound barrier there is a loud bang.

You have made a thread without looking and taking into account the evidence.
Building Seven Collapsed Too you know .
Please could you explain how Jet did this...
Could you explain to me how a normal fire did this..
I smell a fish.
Wish you could vote misleading threads down..

The facade may have been aluminum - but that is irrelevant to the question addressed by the video.
Please don't stray from the topic.
I don't see how that's off-topic. If someone makes an argument regarding molten steel, whether for or against - it's completely relevant to point out that the molten metal did not have to be steel in the first place, and point out the far greater likelihood of it being molten aluminum.
Pointing out the faulty premise, which is on-topic in any argument.
The thread is not about molten steel.
It is about the integrity of structural steel. Specifically that such steel doesn't have to be hot enought to melt to lose it's structural integrity.
Isn't reading comprehension taught in schools any longer ...
Yes it is. And it is also taught that correlation does not imply causation.
Just because jet fuel can weaken steel does not mean that jet fuel was the cause of collapse. It would take a proper investigation to conclude any causation. The 911 commission and NIST report were not proper investigations. NIST was paid a small, finite amount of money to produce a report for a government that already went to war based on the what that report was going to show.
Could you imagine if we were already a year into Afghanistan and kicking off Iraq, then NIST came back and said that these buildings could not have collapsed by the force of heat from jet fuel and office furniture.
Meh, it's not like anyone that reported the findings on 9/11 that resulted in the murder of over a million Afghan and Iraqi citizens, were even under oath.
Oops.

I think you have no idea what to do when someone doesn't state a theory so your system just glitched.
And I wish people could understand simple English. This was never about what caused or who caused the buildings to fall down. It answers/refutes one single element of the complex web of questions and inconsistances surrounding the event
What evidence do you have is was not fire. Think about the fire never before collapse of a high rise.
