Merged David Chandler (ae911) sez "WTC7 was in free fall part of the time"

The expulsions from what I understand are based on similar dynamics as what we saw with the towers, material such as ash, soot (products of the interior fire), and other light weight materials were forced out via air pressure as the structure collapsed. Given that the failure in WTC 7 happened lower in the structure relative to what was seen with the towers, the difference in the behavior isn't that terribly surprising in so far as I can tell.
We only see the top half of the building in that footage; are there any clips taken from ground level, or showing a full face of WTC7 from ANY angle? I realise I could look on Youtube, but that thought doesn't fill me with any joy.
 
If so, how does that fit into a sequence of 'expulsions' elsewhere, where they rise up the building, instead of fall, as you'd expect if air was pushing the windows out. Does your flexing building account for that?

Why would you expect air expulsion to go from the top downwards? The compression is taking place at the bottom of the building, so the pressure wave will travel upwards. Breakages due to air pressure would therefore be expected to start lower in the structure, with a sequence rising up the building. Breakages due to flexure could appear to propagate in any direction, or to take place near-simultaneously (as in this video), depending on the fine details of how the building fails.

The appeal to magic is committed when you correctly identify the problem with your hypothesis (the impossibility of creating a good seal around the lower structure to allow the vacuum to be created), then dismiss it by saying that you're sure some clever engineer can come up with a way of doing it. Your hypothesis rests on the bare assertion that this is possible, despite the physical difficulties involved. As a clever engineer who's good at coming up with explanations for physical impossibilities, why don't you suggest a mechanism yourself?

Dave

You still don't understand, do you? You do not require a seal to produce vacuum or, my suggestion, under pressure.
The WTC7 demolition went fast. No time to set up a seal. Use your brains, if you have any.
 
??? Vacuum = alchemy?

No but the magical and unknown (and unproposed) chemical reaction that reduces the volume of gas in WTC 7 (which was open to the atmosphere) by a huge factor is alchemy and it is positive proof that you are speaking out your nether regions as usual.

[wooville] we perfected the direct vacuum weapon at AFWAL, the labs at Wright Patterson where we keep the alien technology and frozen bodies. Heiwa is right, the direct vacuum weapon is like a vacuum cleaner and PAVEPAWS radar system! Using Electro Magnetic Energy and super-nano- directed-Vacuum technology we were able to use the same electronic aiming used by PAVE PAWS for RADAR to direct the extreme vacuum Heiwa has discovered, in his own head. Top Secret Directed Vacuum, (DV) weapons can do what Heiwa discovered turned WTC7 into ruble. [/wooville]

what a hoot

didn’t the Grinch use this weapon and leak our Top Secret to the world? How do you spell grinch?

Magical and unknown? You talk like an NWO sect member (with no brains in nether (and upper) regions)! OK, you are not alone on JREF Forum in this respect. As usual! Gas in WTC7? Ok, air is a gas. And the atmosphere is full of it. Gas! Gases! Air.
Topic is the strange acceleration of the upper part of WTC7 as established by Chandler and confirmed by NIST and I, friendly, suggest under pressure can assist to explain it. Clever, brilliant, innovative, new, yes! But magic, no. Magic is for sect members with no brains anywhere.

If you read my above post, I just showed the childrens experiment how to reduce air volume (locally), by a huge factor (1/5.2 actually) by lighting a candle. Magic? No!

But this little 20% reduction in air volume/pressure can produce a force producing in turn an acceleration of 0.1 g to any mass it is applied to.

And 0.1 g, 1 m/s², is quite impressive by a small candle.

Please, keep your replies factual and polite. Humour is also appreciated. Topic is depressing and we all want to see the light at the end of the tunnel.
 
So Heiwa is now claiming that some sort of vacuum device brought down WTC7? And for some insane reason he cannot explain how they kept the whole system sealed.

Heiwa are you just having fun by messing with us or are you actually crazy?

The latter.

Oh come on all you have to do is read, the clues are there for all to see...

The whole thing sucks!

Not really! Vacuum is not magic. .

You do not require a seal to produce vacuum .

Here,is the super weapon that was used to demolish WTC 7...

The new "vacuum cleaner" theory is great,not only does this weapon do the job, it cleans up after itself ,therefore removing all evidence that it was there.

Vacuum device? What's wrong with under pressure and no device?

Re devices - I still wonder what software device NIST used to analyse the collapse. It could not possibly be a structural FEA software!

So Hewia, how much pressure would be needed to destroy the columns necessary to destroy WTC7?

And you've never answered whether or not I can share the honor of your Stundie Award for the month of November since I nominated you for it.

Not sure why I am arguing with you since I am positive you are either insane or a troll. I am intoxicated so maybe that is why.

According NIST, using unknown software to analyse the structure, you only need to remove one piece of one column, no. 79, between two floors, 11/13, and the whole thing self-destructs in 6 seconds, 2.5 of which are free fall, as shown in the NIST WTC7 report.

No pressure at all is required for this 6 s Hollywood show. Look at the pictures in the NIST report. Parts flying around, etc. A child knows it is fantasy.

In my opinion you have to remove most columns below floor 11 to start the show. It takes two seconds. How is this done? I will tell you later. You have to be patient.

As some columns are still there providing resistance, you need under pressure below floor 11 to suck down the structural assembly above floor 11 at free fall. Gravity alone cannot produce free fall, when there are columns below providing resistance, you see. This part of the show takes 2.5 seconds.

And when the structural assembly above floor 11 hits ground after these 2.5 seconds of free fall, evidently, visible things slow down (the upper part assembly self-destroys) during another 2.5 seconds due to contact with ground (no more free fall) and produces a big cloud of dust to hide the manipulations done previously.

Now, re question about removing columns, etc., the info to answers is secret. Husch, husch. You know. If published anybody can start demolish buildings right and left.

You are instead, kindly, requested to inquire NIST about its magic software.
 
He ignores the fire damage to the rest of the structure. Why?

He says remove one column and the structure fails; Does he assume no damage to the rest of the building after fire burned and was not fought all day?

As for him being an engineer, he is not using his engineering stink here, and he must of forgot all he was taught since he is making up junk as he goes.

How many people have this engineer’s failed ideas on ignore?

I have feeling he failed to read NIST's report on WTC7.
