Questions and Answers about the NIST WTC Towers Investigation
In no instance did NIST report that steel in the WTC towers melted due to the fires. The melting point of steel is about 1,500 degrees Celsius (2,800 degrees Fahrenheit). Normal building fires and hydrocarbon (e.g., jet fuel) fires generate temperatures up to about 1,100 degrees Celsius (2,000 degrees Fahrenheit). NIST reported maximum upper layer air temperatures of about 1,000 degrees Celsius (1,800 degrees Fahrenheit) in the WTC towers (for example, see NCSTAR 1, Figure 6-36).

What does Richard Gage, Steven Jones, Gordon Duff, have to do with the seismic graphs that we are discussing?
You keep talking about how bad all these A&E scientist are yet I have not seen their work debunked on ATS, why is that?
Debunked: AE911Truth's WTC7 Explosive Demolition Hypothesis
www.metabunk.org...
Actually, nothing, but where's the demolition spikes in the WTC seismic data? I do not see any demolition spikes in regard to the seismic data. I see spikes for the collapse and impacts, but none for demolition explosions, which would have been evident proceeding the collapse of the WTC buildings, but there are no such spikes depicted on the WTC seismic data.
North Tower collapse (10 nm/s instead of the original 100 nm/s), you see that the amplitudes RUN OFF the graph, evidence of explosives when checked to the real Manhattan times of origin, 17 secs earlier :
South Tower collapse (10 nm/s instead of the original 100 nm/s), you see that the amplitudes RUN OFF the graph, evidence of explosives when checked to the real Manhattan times of origin, 17 secs earlier :
This is the first North Tower its plane impact seismogram (original sensitivity in 10 nm/s), note the huge difference in amplitudes with both collapse seismograms :
This is the second, South Tower its plane impact seismogram (original sensitivity in 10 nm/s), note the huge difference in amplitudes with both collapse seismographs :
Have you ever wondered why "AE911 Truth" has been challenged by other 9/11 conspiracy theorist? Have you ever wondered why associates have been jumping off the bandwagon of "AE911 Truth?"

But yet I have never seen anyone debunk their science,
That is simply because the do not post any science, just opinions.
Care to show some science they have posted?
• A collapse zone is defined as the area around the perimeter of a structure that could contain debris if the building collapsed. This area is often defined by establishing a perimeter at a distance from the building that is equal to 1.5 times the height of the structure.

I find it interesting that there were counter terrorist professionals on the day who believed that one reason they waited up to an hour before blowing the buildings

That video has been debunked. For an example, listen to what he says at time line 4:48. Now, take a look at this photo.

That photo alone debunks that segment of the video. Now, go to time line 0:36 and you will notice that debris, which are falling at free fall speed, are outpacing the collapse of the WTC Tower which effectively debunks the claim the building collapsed at free fall speed.
Now, head to time line 5:18 to 6:00 and listen to what is being presented, but let's take a trip over to NIST to see what it said about the temperature levels.

In other words, that video is spewing false information.
Typically you have the primary event/explosion to attract the rescue services to a location, then they detonate a much larger secondary payload when the first responders arrive at the scene. In the case of the towers, the planes would of been the primary event to attract the rescue workers, and bringing down the towers being the secondary event to kill and injure as many of those first responders as they could.

The hard facts are the first building stayed up for 102 minutes.
The second only 55 minutes. About half as long as the first.
That's a long time to allow scared people and first responders to stumble over demolition evidence.
Even if they didn't make it out they could have radioed or cell phoned what they saw.
There's even a audio of a man on the phone as the collapse starts. No demo sounds.
Also, would there not have been a chance of demolition equipment being thrown clear by the aircraft impacts? The effort required to subtly rig the WTC for demolition and have no one know would be like the effort required to go to the Moon.

There are so many that I can not post all of them, however you can go to this link that I have provided for you. and read them.
I would expect it will take you a week to read all of them.

Ok WEAKENED a 6" thick steel box column in either 102 or 55 minutes, .... from jet fuel induced office fires etc.
twisting the bars when hot. Officers should be instructed that bars simply bent may be used again, but if when red hot they are twisted out of line they cannot be used again. Pile the ties into shape for a bonfire, put the rails across and when red hot in the middle, let a man at each end twist the bar so that its surface becomes spiral.
