Dear CameronFox,
you say there isn't any failure to the building after the squibs are set off?
Yet there is failure to the building after the squibs are set off, total and catostrophic failure only a seconds later (if that)! Besides the plan was more about destruction than creating failure.
Remember, these were two of the largest buildings in the world! If it were official C.D it would of been a record breaker, not to mention a monumental task.
There was so much more explosive energy required and a much larger area to be destroyed than an average C.D job. The explosives were not planted at the edges of the outer walls, but rather deeper in the central core.
The pressure is moving faster outwards than the visible destruction. C.D usually happens from the base and travels upwards, this was a wave of destruction travelling downwards.
It cannot be compared to other C.D jobs since all the C.D videos we see are of very small and weaker buildings using different techniques, lower yields and different types of explosives.
These squibs are huge and centralized! If it were simply caused by pressures from above then they would of been bursting out on all the floors all the way down in chorus and I doubt anyone would question it. However they emerge from limited locations and are centralized.
But if we examine the anomaly closely, we see these [would be] explosives work in reverse to an explosive blast. They tend to spurt out and then increase with time. An explosive works in reverse to this. Its strongest point is the moment the charge is set off. It doesn't increase its explosive strength with time.

So why then does the building not fail until the rest of the building catches up? To me that indicates it's the falling building doing the damage.

Those "couple of seconds later (if that)" is when the falling floors and tower hits the "squib zone". In a real controlled demolition you can see the building shift where the bomb goes off milliseconds afterwoods.

Yes, which would have taken 12 men over 72 straight days to prepare.
There was so much more explosive energy required and a much larger area to be destroyed than an average C.D job. The explosives were not planted at the edges of the outer walls, but rather deeper in the central core.
Why is it then, that the core was the last part of the building standing?
The pressure is moving faster outwards than the visible destruction. C.D usually happens from the base and travels upwards, this was a wave of destruction travelling downwards.
Which is typical of a pancake collapse, but not of a controlled demolition.

Well why are you doing it then?
These squibs are huge and centralized! If it were simply caused by pressures from above then they would of been bursting out on all the floors all the way down in chorus and I doubt anyone would question it. However they emerge from limited locations and are centralized.
Not necessarily. The "squibs" would simply occur where the lest resistance to the compressed air is. For instance, the wind would relieve pressure via a broken or cracked window before and intact one.
What is interesting is the way these "squibs" work. They appear to act in an exact reversal of normal explosions.

I fail how you can link noises and machinery on a construction floor to a controlled demolition. To be honest if there was construction going on upstairs and everything was completley quiet - then I would be worried.

Good points, I will have a go..
point 1: perhaps the pressure from falling floors above was required to finish that section off?
point 2: It was deep inside rather than at the edge, so there was not really any visible effects on the outside like explosions or a fireball. I already said this wasn't really a C.D, if we could strip away the outer walls and see what was actually happening inside it would tell a different story.
point 3: 72 days with 12 men? I would like to know how did you arrive at that figure? I figured it would be more like 40-50 men working for a few years!
point 4: the core was a much harder target!
point 5: whenever has a pancake collapse created micron scaled devistation of concrete and charred wrecks of cars that weren't even hit by the debris?
Microscopic analysis of WTC dust by Nicholas Petraco, BS, MS, DABC, FAAFS, FNYMS at The New York Microscopic Society lecture held at AMNH 28 May 2003
45.1% Fiberglass, rock wool (insulation, fireproofing)
31.8% Plaster (gypsum), concrete products (calcium sulfate, selenite, muscodite)
7.1% Charred wood and debris
2.1% Paper fibers
2.1% Mica flakes
2.0% Ceiling tiles (fiberglass component)
2.0% Synthetic fibers
1.4% Glass fragments
1.3% Human remains
1.4% Natural fibers
trace asbestos (it became illegal to use during the construction of the WTC)
Other trace elements: aluminum, paint pigments, blood, hair, glass wool with resin, and prescription drugs were found.

point 6: I am? More like I am comparing it to how it is unlike a C.D.
pont 7: Highly unlikely, unless you can show me the exact points where the squibs are in relation to how little resistance these area were, there is no indication these areas were any weaker than others most of the floors were practically identical excluding the sky lobby areas.
point 8: different type of explosives produce different results.
The plot compares the concentration ranges and mean concentrations of chemical elements in the WTC dusts (this study) to the mean concentrations of the same elements in soils from the eastern United States (other studies).
Results :
Implications for Dust Cleanup As stated in the initial USGS report to emergency response workers on Sept. 27, 2001, the materials identified by this study in the WTC dust and debris (chrysotile asbestos, glass fibers, alkaline concrete particles, potentially soluble metals) indicate that cleanup of dusts and the WTC debris should be done with appropriate respiratory protection and dust control measures.

A comfortable walking speed is around 3.1 mph There are 5280 feet in a mile. So 3.1 mph = 16368 ft. per hour, which is the same as 272.8 ft. per minute, or 4.5 ft. per second.
Each floor was 12 feet high. Assuming the stairs were at 45 degree angles (which looks as if it creates additional distance than was actually there because of how steep it is), we can get the following:
By Pythagorean Theorem, a² + b² = c². whereas c is the hypotenuse, and a and b are the remaining sides. So 144 + 144 = 288, and the square root of 288 is 16.97, which I'll round up to 17. Therefore we can estimate the stairs being about 17 feet long per floor.
I'll throw in 10 feet on each floor between each set of stairs. So we have 17 feet of stairs per floor, and 10 feet between each set on each floor.
17 ft. + 10 ft. = 27 ft.
27 ft. * 33 = 561 ft.
So we can estimate about 561 ft. to walk up 33 floors of stairs.
According to the earlier figure of 272.8 ft. per minute, at a comfortable walking pace, 561 feet can be comfortably walked in a little over 2 minutes. Therefore, if Rodriguez was moving fairly quickly, and given the circumstances we can assume he was, then it would've taken him less than 2 minutes to climb up those 33 floors. If he was jogging at about 6.2 mph, it would've taken him 1 minute to climb the 33 floors.
1 minute to climb up, 2/11 of that time to climb an additional 6 floors (6/33 = 2/11) and the same time doubled to come back down, leaves him about 13 full minutes to actually help people and not just running up and down stairs.
He had plenty of time.
This man was one of the heros of 9/11, yes, but not because of any superhuman abilities. Any healthy person could do the physical work he did in the given amount of time; I've just shown it wouldn't be hard - at all. You should be ashamed for accusing this man of lying in the first place.

I would like you to read this post of mine :

The most interesting part for this discussion is the USGS WTC dust investigation fact sheet and its plotted chart.
They found about 1% asbestos in their dust samples. They were however forbidden to sample at Ground Zero, only around it !

Sorry; I just proved mathematically that it wouldn't be that hard, judging by the distances involved. There would be time to spare to allow people to pass on their way down; no problem.
You can speculate all you'd like, but his testimony adds up perfectly as it stands. Sorry Howard.
