Wouldn't want the mechanicals falling off to the NE and damaging the Fitterman building...... oh, wait!
Where can we get the silent explosives, ones which only blast out four windows? Your fantasy CD has silent explosives, can you explain how they work, and don't blast out more windows? 13 years, you must of found a reality based source for your explosives which leave no evidence by now.You are putting words in my mouth. I have never said I thought column 79 was the initiating event in the collapse of WTC 7, with or without extra explosives. ...
It is interesting how free fall=explosives is slowly being dumped. When first brought up it was supposedly obvious that the only way to accommodate that was to blow every single column, including the perimeter columns thus bringing the entire structure at 'g'.
When challenged on the sound of such enormous use of heavy column cutting charges, well now the explosives all move to the interior with both MM, and Szamboti throwing Chandler under the bus.
He was pushed on this question once before and the best he could come up with was to say it was to prevent the EMP from toppling off sideways. He never did explain why it might do that or why anyone would care.
In other words, "That's what they did so they must have had some reason."
Tony, A couple remarks. First: when I first noticed the light shining through only the top windows of Building 7, I immediately assumed that we saw sunlight there because of the angle of the video camera. Placed on the ground and looking up diagonally, the line of sight inside the windows would have sunlight pouring in the top windows simply because at this steeper angle, you end up seeing above the partial lighjt barrier of the other walls. So after those top floors with light pouring in, you have a lower angle, and those lines of sight would come up against the far outer perimeter wall which was still standing and therefore blocking any direct view of the bright sky. You seem to be saying that the East Penthouse dropped a few floors and then stopped. Is that a correct understanding of your position?You are putting words in my mouth. I have never said I thought column 79 was the initiating event in the collapse of WTC 7, with or without extra explosives.
I have said it appears to have been removed only high in the building to take the east penthouse down. My reasons for that are that daylight is only visible in the top story windows afterward, there is a shock wave from top down which only breaks windows from top down for about fifteen stories, there is no white dust emanating from windows on the east side until the entire exterior comes down, and there is no exterior deformation during the time that NIST alleges the full east side interior is collapsing.
I have also said (on this forum and other places) many times that I believe eight stories of core columns were removed somewhere low in the building to cause the collapse. I also don't see a need to artificially remove exterior columns, as they would be left unsupported and pulled in by the falling core. This is what Danny Jowenko thought also.

As for the freefall, now you are saying that it wouldn't be necessary to rig the perimeter walls (I certainly agree there!) and knock out all structural support even with freefall happening. David Chandler once told me that every column had to be rigged for there to be freefall. He said about CD, "Building 7 was overkill." Are you saying it is NOT necessary to knock out all structural support to attain freefall + of the perimeter walls of Building 7? Or are you saying that knocking out the lower floors enabled the whole perimeter wall to attain freefall for a few seconds?
Finally, are you aware of femr2's very accurate measurements of the rate of collapse of the perimeter wall of Building 7? He claims (and it's even visible in the graph in the NIST Report) that for about 0.75 seconds, the perimeter wall attained greater than freefall acceleration. Do you accept his data, and how do you explain greater than freefall collapse without acknowledging the leveraging and torquing from the inner collapsing structure to the outer perimeter may have actually "yanked" it down even faster? And if torquing and leveraging may have more than overcome any residual resistance for those 2.25 seconds, why do we need CDs to explain the collapse based in the rate of its descent?
WTC 7 was 144 feet wide and if the entire east side interior had been collapsing when the east penthouse went down there certainly would have been sunlight seen through more than just the top story windows. Your camera angle theory does not explain it away.
Removal of eight stories of the core would have left the exterior unsupported for those eight stories and caused it to buckle. The minimum resistance during buckling over an eight story column length would have been less than 5% of the column strength. The falling core would also be pulling the exterior inward, through the attached beams, so the exterior would essentially fall in free fall and it actually could experience a little higher acceleration than gravity due to a whip action from the already falling core.
See above answer. There is nothing strange about it. However, 0.75 seconds of a miniscule amount of acceleration above gravity would not explain residual resistance being overcome to retain freefall for the next 1.50 seconds. That is really a silly notion. The only way to get a symmetric free fall over eight stories is for the entire 24 column core to have been removed over eight stories. The mechanics are also right for it to include a slightly over free fall acceleration at the beginning due to the whip action of the already falling core.
The problem with accepting the NIST claim of a naturally collapsing interior (core) progressing from east to west is that the exterior of the building comes down over its full length and width simultaneously. There also wasn't any exterior deformation on the east side when they say it was collapsing first and then spread to the west. The core would have been removed starting in its center and moving outward to effect a pull-in and keep the fall somewhat tight. The difference in timing between inner and outer core columns being pulled would only have been fractions of a second. The core removal, starting at its center, is very likely to be what caused the horizontal kink in the north face as the collapse started.
The east penthouse being taken out by removing column 79 high in the building and eight stories of the entire core being removed to cause the full collapse shortly after can explain everything that is observed.
Where about? You mean the building exterior ?A free standing granite wall would be laid after building erection and not strongly attached to the steel mostly just stabilized by it.

Even so, there apparently was enough deformation of the wall under the east penthouse to break windows down about as far as any of the videos show:

Only questions, how does this fit your "new approach"?Where about? You mean the building exterior ?
Fire did it. the realcddeal, is BS...

Call it 80 columns, with 4 cutter charges per column per floor, minimum. That's ~2500 explosions happening in a very short space of time. Didn't happen, people would have noticed You're talking delusional claptrap.
That's your right, of course, but you still need to explain why anybody might go to such lengths and take such risks to destroy an inconsequential building. Oh, and how they would have proceeded if WTC7 hadn't been set on fire.
There were 24 core columns in WTC 7.
The fires in the building were most likely due to arson to provide some sort of cover story for the collapse, as it seems impossible for the North Tower collapse occurring 350 feet away, with only about 4% of it aflame and collapsing with copious amounts of fire dousing gypsum dust, to have caused fires on ten floors of WTC 7. There also is no photographic evidence of the fires in WTC 7 until 12:15 PM (nearly two hours after the North Tower collapsed). The story is quite weak and I am surprised people are falling for it.
