World Trade Center's North Tower on Sept. 11, 2001.

[eots]

you taking the same stupid pills as rdean now?

Pills are science-based, so you don't believe in them.

dont tell me what i do or dont believe in, moron

You do not believe the NIST report...as you contradict it all the time...debwunker

 

[eots]

The question was if it had been "free fall "how long in seconds... how fast in MPH.

You have the formula...do your own math fuck head....

See I know the answer.
You dont, but you keep referring to this magic mythical number. Provide it so people can judge for themselves if it is reasonable.

What was the design capacity for each floor and what was the combined weight of the floors about the impact site?

I know the answer I am just not playing your childish game...and if it is seconds instead of MPH...it is hardly a magical number...dipshit

I saw airliners crash into each of the Twin Towers, both of which collapsed shortly afterward. Various experts have attributed the collapse to the melting of steel support braces and columns by burning jet fuel.

That explanation continues to be rejected by an endless parade of skeptics who boldly insist or obliquely imply that the collapse of the Towers was the result of controlled demolition. But I have never seen or heard so much as a vaguely detailed suggestion of how such a project might have been carried out, who would have organized and directed it, how many people would have been involved, what materials were required and how was access facilitated.

Has anyone here seen or heard any such speculation?

Quick note: I don't think you've seen any real experts attribute the collapse to the "melting" of steel supports unless they just mis-spoke. What experts have said is that the fires weakened the steel as to where they could no longer support the load on top of the weakened area.

As for the rest of the post, you're right no twoofer/truther has ever offered anything close to a satisfactory explanation of how, why, and when. The reason is that if an episode is written down in black and white; 2 things happen:

1). The story sounds like garbage and there is no way to sugar coat it.

2). The implausibility of the story is subject to being assailed and since something is now written down, people like Mr. Jones, EOTS, Rimjob, Miller, etc.... can't back away from what they wrote; so they are too scared to write it. In the old days, we'd call that cowardice. Today the politically correct term is that the twoofers are nothing but a bunch of "pussy-whipped idiots." I certainly invite any and all narratives but suffice to say that it would be a stunning development that hasn't happened in almost a decade.

If illustrating that you are a parrot of someone else's misinformation is a childish game feel free to stop at anytime. If you are a capable investigator with the knowable facts at hand, prove it. If the building had collapse at free fall how long in seconds, how fast in MPH.

What was the design capacity for each floor and what was the combined weight of the floors about the impact site?

 

[The Infidel]

yes, its all over the conspiracy theory forum
but they have yet to show a single piece of evidence to support a controlled demolition

They dont have to.... they had Allah on their side.

 

[The Infidel]

The majority of the towers consisted of open space between the core and the out supports.
What outside forces present would have made the towers collapse in any manner other then into its own footprint?

uneven damge...uneven distrubiton of fire would not create a symetrical and complete collapse in seconds not once but three times !!!...give your head a shake

Given the uneven heating on the floor joist what would the effect be on the angle clps

"The 9/11 Commission Report" (p. 322): "the South Tower collapsed in ten seconds".
http://www.9-11commission.gov/report/911Report.pdf

These collapse times are close to that of a billiard ball dropped from the top of WTC 1 or 2. The time is calculated using the equation taught in high school physics classes: Distance = 0.5 X Acceleration X Time Squared.

Using this equation a billiard ball dropped from the top of the 1368 feet tall WTC 1 or 2 would travel 1296 feet in 9 seconds -- it would reach the ground in 9.2 seconds (assuming acceleration due to gravity of 32 feet per second per second, and no wind resistance).

The South towers' collapse in 10 seconds -- at near free-fall speed, due solely to airplane impact and the resulting fires, defies logic.

Hey dumbass. According to your link, it's page 305. Do you even read shit for yourself or just copy and paste what others say?

Anyways, 10 seconds is incorrect. You, being a complete idiot, probably can't figure that out for yourself.

 

[Gamolon]

uneven damge...uneven distrubiton of fire would not create a symetrical and complete collapse in seconds not once but three times !!!...give your head a shake

Again, it wasn't 10 seconds.

Put the weed down for a few minutes and maybe you'd figure it out.

 

[eots]

uneven damage...uneven distribution of fire would not create a symmetrical and complete collapse in seconds not once but three times !!!...give your head a shake

Again, it wasn't 10 seconds.

Put the weed down for a few minutes and maybe you'd figure it out.

Put the psych drugs down and you may become suicidal...so you best keep talking them..I guess

NIST, own words are near-free fall it is not up for debate

You just keep fucking up don't you?

Here is NIST's actual words about the collapse times taken from this website:
NIST's Investigation of the Sept. 11 World Trade Center Disaster - Frequently Asked Questions

NIST estimated the elapsed times for the first exterior panels to strike the ground after the collapse initiated in each of the towers to be approximately 11 seconds for WTC 1 and approximately 9 seconds for WTC 2. These elapsed times were based on: (1) precise timing of the initiation of collapse from video evidence, and (2) ground motion (seismic) signals recorded at Palisades, N.Y., that also were precisely time-calibrated for wave transmission times from lower Manhattan (see NCSTAR 1-5A).

As documented in Section 6.14.4 of NIST NCSTAR 1, these collapse times show that:

“… the structure below the level of collapse initiation offered minimal resistance to the falling building mass at and above the impact zone. The potential energy released by the downward movement of the large building mass far exceeded the capacity of the intact structure below to absorb that energy through energy of deformation.

Since the stories below the level of collapse initiation provided little resistance to the tremendous energy released by the falling building mass, the building section above came down essentially in free fall, as seen in videos. As the stories below sequentially failed, the falling mass increased, further increasing the demand on the floors below, which were unable to arrest the moving mass.”

In other words, the momentum (which equals mass times velocity) of the 12 to 28 stories (WTC 1 and WTC 2, respectively) falling on the supporting structure below (which was designed to support only the static weight of the floors above and not any dynamic effects due to the downward momentum) so greatly exceeded the strength capacity of the structure below that it (the structure below) was unable to stop or even to slow the falling mass. The downward momentum felt by each successive lower floor was even larger due to the increasing mass.

From video evidence, significant portions of the cores of both buildings (roughly 60 stories of WTC 1 and 40 stories of WTC 2) are known to have stood 15 to 25 seconds after collapse initiation before they, too, began to collapse. Neither the duration of the seismic records nor video evidence (due to obstruction of view caused by debris clouds) are reliable indicators of the total time it took for each building to collapse completely.

That would be the Commission Report that said a 10 second collapse time.

It's not a 1 second difference moron!

Here eots. I'll TRY and make it simple for you to understand.

Here's what the Commission Report says:

...the South Tower collapsed in ten seconds...

Do you see the difference between NIST saying the EXTERIOR PANELS took 10 seconds to fall to the ground and the Commissin Report saying the TOTAL COLLAPSE took 10 seconds?

Or are words like "ground", "took", and "the" making it to complex for you to understand?

How could portions of the core standing for 15 to 25 seconds after the collapse initiated equal 10 second collapse times?

 

[Liability]

If an EXTERIOR panel fell in the range of 10 seconds, that might be close to free fall. OF course, there's nothing to impede the fall of an EXTERIOR panel, so that conclusion isn't exactly a surprise, now, is it?

The estimates (should I put "estimates" in bold and large font?) for the collapse of the INTERIOR structures do not come CLOSE to 10 seconds. This MIGHT have something to do with the fact that there WAS stuff impeding the fall of INTERIOR items.

"FREE FALL" claim these Troofer idiots.

"No," respond the folks who prove that the Troofers are making shit up.

"But but but, NIST said it," respond the idiot Troofers.

"Again, no," point out the ones trying to educate the Troofers, "that's not what NIST said!"

And then the Troofers simply and mindlessly loop what they've already said.

they fell at free fall speed...how did the mass increase when the concrete was pulverized and huge steel beams were sent flying outward ?were did the energy to do that come from in a free fall collapse ? ...if it happened as you say you would expect to see floors stacked like pancakes and the core remaining

You lack basic reading skills. You are SO enveloped in wanting there to be a conspiracy, it's clouding what little you have left of a brain.

This:

they fell at free fall speed

Does not equal this:

the building section above came down essentially in free fall

Do you get the difference yet? You are completely mixing up the two explanations. They are saying the TOP portion fell at free fall because the COLUMNS FAILED. You are saying that the towers COMPLETELY COLLAPSED in 10 seconds.

Damn are you stupid!
