Saying there were more than ten floors on fire in WTC 7 makes the argument that they were caused by the North Tower even more untenable than it already is. It is one giant hand wave by NIST to say fires on ten floors, that show up nearly two hours after the North Tower collapse, were caused by that collapse.
How odd of you to say that. The ONLY evident cause of the fires anywhere, post collapse, is as a result of those collapses either by burning/hot debris, or from sparks or disruption of electric current carrierers. Yet you reject such reasoning out of hand and proclaim that a cadre of unseen arsonist spooks were running about lighting up a building that had suffered very significant impact damage and/or unseen 'leftovers' of a material that cannot conclusively be said to have existed in the area sprinkled about and ignited ( in the case of WTC7, By your very own reasoning, two hours later.
They don't bother to explain the problems with it such as the two hour delay, the massive amounts of gypsum dust that would extinguish the flames in WTC 1 during the collapse,
Asked a few times now and you seem to miss it every time Tony. That gypsum dust is created as collapse ensues , that dust then supposedly coats burning materials and stays coated on those materials as that material exits the building less than a second after collapse initiated. That gypsum dust is from drywall that was very hot in the first place. Its water content would have been significantly gone by the time of collapse. So its not cooling ,all its doing is reducing oxygen availability. Now, by your own reasoning, at some distance from the towers the dust density is no longer sufficient to stop combustion. Materials from the towers would take around ten seconds to reach WTC7 ,. Can you demonstrate that something that was on fire in WTC1
could must cool below its ignition temperature, and the ignition temperature of common office contents in WTC7, within ten seconds or still have a thick enough layer of gypsum dust coating it when it bounces into an office of WTC7?
increasing the fact that there were fires on just a few floors in WTC 1,
Nonsequitor. You have blatantly tried to downplay the fires in WTC1 by talking about them in relation to the total office space in the entire building. Why not just go that extra inch and talk about the percentage of office space in Manhattan south of WTC7 that ewas on fire, or the percentage of office space on fire from WTC1 to Long Island? Your comparison is just as absurd.
the 350 foot distance between the buildings, and the fact that the Verizon and Post Office buildings had no fires
.
Again, can you demonstrate that materials that were ejected from WTC1 fire floors MUST be cooled below the ignition temp of common office materials in WTC7 or be coated in a blanket of gypsum dust after this travel ?
Your argument that there were even more fires in WTC 7 than NIST claims makes the case for arson even greater
No, it doesn't. No more do than saying a DEW did it, or pixies from Mars. There is absolutely no evidence of arson spooks beyond your own imagination. PERIOD.
As for the Verizon and Post Office. First let's deal with the Post Office. We note thgatbtge eastern side of WTC7 itself suffered much less window damage than ntge western side. So right away we can assume, without even checking the record, that the P.O. suffered much less than WTC7 wrt impact damage. Its windows were also wire reenforced.
OK, the Verizon building. The greatest number of broken windows on it were at its eastern end. Photos show it suffered much less impact damage than WTC7 did. No large holes such as seen in the SW corner of WTC7. So it might behooze you to explain exactly why you would expect an nequal number of fires in it as in #7.
The problem with your argument isn't about the >g component. It is that the symmetric free fall, or even >g fall, of the exterior of WTC 7 couldn't happen with the sequential exterior column collapse NIST argument that you support. The argument with the symmetry and sequential column failure involved together is not coherent.
The eastern third of the building had a very different core structure than the western 2/3rds. The facade first failed along the line of the 'kink' which is the area of the join between the east and west. Why do you keep trying to say that the entire building was so very similar that it could only fail by bringing down 24 core columns all at once?
The third force you are talking about would be the pull-in of the entire exterior by the falling core. The entire core had to be dropping at the same time to get the symmetric exterior collapse that we witnessed. The entire core is not dropping simultaneously with the NIST east interior collapse first and then east to west progressive interior collapse. That is why their model does not replicate the real event.
No, as I pointed out many times, the north side facade had already failed along the line of the kink. The south side was missing its SW corner while the eastern 1/3 was largely unaffected by WTC1 debris. That means that at global collapse initiation the larger part of the building would have its SW and NE ( the kink) already failed. The eastern third had its NW corner (at the kink) compromised, was a smaller structural section , and did not rely on the core construction of the western 2/3rds BUT would be attached to that western 2/3rds by 40 storeys pulling on it.
In fact the eastern portion twisted and fell in the opposite direction as the western portion, again indicating a differential response to the forces in the collapse.
But you completely ignore that in favourite of arson and demolition spooks. Why is that?
