This is an illustration that you are incapable of critical thinking because 0.99 is awfully close to 1.00.
No point in trying to put me down here, this is a quote from one of the Structural Engineers, not me. If you don’t agree with them, go and say it to them.
You have claimed that there is no other credible explanation other than controlled demolition for the ‘freefall’ episode. To contradict this statement, it’s necessary for me to show that there is another explanation accepted by a significant number of qualified people - and this I have done. The great majority of Structural Engineers do not agree with you or Chandler.
Despite the name ‘Architects and Engineers for 9/11 truth’, most of their membership are neither. They have failed to recruit the industry to their cause. As far as I have seen, none of them were actually present at the collapse.
Why don’t you listen to the people who were actually there? The first senior fireman on the scene after the South Tower hit could see instantly that the damage was terminal and that the building would collapse.
There never was any need to ‘explain’ the collapse, it was plain from the first. All these theories have been generated by people who were not at the scene.
This is why there were no casualties in WTC 7.
One of the many insidious acts of the Truthers has been to trawl through fireman and bystander testimonies to find phrases like ‘it sounded like an explosion’ etc. These have been taken out of their context and published together. In context, any apparent significance disappears. The Truthers may have isolated quotes, but they don’t have ‘testimony’. Not one emergency worker supports their account. There simply is no convincing account of the upwards of 100 sequenced explosions that would have been necessary to bring down this building. In addition, it doesn’t show up on the seismic record.
I haven't heard a theory for when or how any explosives were placed in WTC7 which is irrelevant to the present discussion.
This doesn't seem to make sense – did you mean to say ‘relevant’ instead of ‘irrelevant’?
It’s almost impossible to see how any explosives could have been laid in place. In a normal controlled demolition, the building is literally ripped apart to prepare it over a period of months, expose beams etc. Similar problems bedevil the Twin Towers conspiracy theories. There is no single period of opportunity that works for all three locations. Even the episodes that have been suggested (renovations etc) are not really suitable for the work required, or don’t cover enough of the building. In the case of WTC 7, the notion that it could have been done in 1989 is doubly crazy because the explosives are not stable over such a long period.
How does it explain evidence of incendiary thermite including iron-rich microspherules and rapid oxidation and intergranular melting of steel columns?
Again and again, it's as if you only have read the Truthers side of these arguments, not the debunking. Both of these issues have been answered extensively and it would take another 10 pages to do it here. Surely you must have read some of this. Some of the Truthers material is deliberately falsified, changing the date on photos etc.
In the case of thermite, or ‘nano thermite’ (it’ll be kryptonite next), there is almost no experience of using this for controlled demolition (just one building in the 1930s I think). In addition, it can only be used on horizontal beams (so why do they show photos of supposedly ‘cut’ vertical beams?). It’s hard to believe anyone would risk using such an unusual, untested material in a circumstance where 100% success was crucial. It’s just one more improbability heaped upon a mountain of others.
Whichever form of explosive was used, it would have required literally miles of wiring running upstairs and downstairs plus other items like detonator caps etc, parts of which
always survive the explosion. No such items were found by the many 100s of workers who cleared the site. For this reason, Truthers have to include hundreds of construction workers into the conspiracy too, along with all the firemen etc.
How does this model explain the BBC broadcasting live that WTC7 had collapsed while it was still visible behind the reporter saying it had collapsed?
It’s strange how you don’t want to talk about the practicalities of laying explosives - without which the event could not have taken place - but you do lay stress on the opinions and behaviours of tv journalists – which affects nothing.
During an event like this there is terrific confusion. In this day of instant, live news, many false reports are given and later corrected. Everyone knows the Twin Towers by name, but WTC 7 was not exactly an iconic building. The BBC analysed how this mistake was made. The original report was picked up by Reuters from a local news agency. By the time they had corrected it, the BBC had already made their broadcast. In addition, it was known many hours beforehand that WTC 7 was going to collapse, and this information was not a secret. This is mildly embarrassing for the BBC, but not otherwise significant. Amazing that you should find this worth spending more than a minute on.
*Lastly
The WTC 7 collapse is a highly complicated argument involving all kinds of specialisms, as well as a vast mountain of testimony. Yet, you react very emotionally to any suggestion that I should not simply ‘look at Chandler’s video’ and be instantly converted. So emotionally, that you resort to the old McCarthyite strategem, 'if you don't agree with me, you must one of them'. You are in practice accusing me of being a mass murderer. You are obliged to lump thousands of eyewitnesses and ordinary workers into the same category for this theory to hold together. I have the benefit of knowing for certain that you're talking crap about me, and I also put my trust in all those ordinary guys going about their jobs, rather than a bunch of self appointed experts like Chandler and Gage, who have made a career out of 9/11. Follow the money - it doesn't lead to Silverstein - it goes straight to Gage and the Truthers.
