I misspoke. Obviously the north face isn't perfectly intact during collapse because it's collapsing and is therefore being destroyed. I mean the north face just prior to the onset of collapse. There is nothing to indicate that some structural failure has occurred to the north face columns before its roofline descends.
Documented how? You mean it was written down after being assumed? The north face, structurally, is completely intact during collapse. There is no evidence to suggest otherwise. The columns that make up the north face, for 2.25 seconds, were unable to resist collapse to any degree. There is no logical reason for this.
No you don't. I've gone into quite a bit of detail as to how steel columns offer resistance, even when buckling/failing.
Hi tempesta29!You haven't demonstrated how it doesn't fit into my theory.

...consistently ignoring the fact that this doesn't apply in Stage 2.No you don't. I've gone into quite a bit of detail as to how steel columns offer resistance, even when buckling/failing.
I don't claim it's impossible. I claim no one proposing controlled demolition has explained it. Until you can articulate a controlled demolition theory that explains it, you are applying a double-standard.You haven't said a damn thing about why Stage 1 is impossible under a controlled demolition. In fact, this is the first I've ever even heard you mention it.
*WHAT* theory?!?!? Where were the charges placed? What type of charges were they? What was the timing of their detonation? What was the sequence of events that caused the acceleration curve on the descent of the north face roofline? How does the collapse of the east penthouse several seconds prior work in to all this?You haven't demonstrated how it doesn't fit into my theory.
As of right now, I don't have ANY reason to even consider a controlled demolition. A bald assertion that a fire induced collapse cannot have a collapse stage that approaches freefall is not enough. You have failed right out of the gate.As of now, you've given no reason as to why Stage 1 isn't applicable under a controlled demolition. You're obviously claiming Stage 1 doesn't fit so let's hear your supporting argument.
Let's try again then ...
Assuming a fire-induced failure what clue(s) would you expect to witness, prior to the beginning of the roofline descent, to indicate that the N face was about to collapse?
Assuming a CD-induced failure what clue(s) would you expect to witness, prior to the beginning of the roofline descent, to indicate that the N face was about to collapse?
I'd also like to hear tempesta's theory.Hi tempesta29!
Perhaps you could outline your theory, so we could avoid confusion on this? If you think it's off topic, you could post it in this thread.
Thanks!![]()
If we are assuming a fire induced collapse, and we take into account the 2.25 seconds of free fall, then I would expect to see evidence that those columns are already fractured. That's the only way I can see free fall being possible.
As for a CD, I wouldn't expect to see anything "wrong" at all because levels are taken out sequentially.

So, with 7 hours of unchecked burning...and multiple internal failures and collapses leading up to the final collapse...your hanging your toofer-cap on the 2.25 seconds of near free fall as proof of a conspiracy?
A sequential CD rules out thermite, yes?As for a CD, I wouldn't expect to see anything "wrong" at all because levels are taken out sequentially.

Why don't you apply this same standard to the CD proposal?If we are assuming a fire induced collapse, and we take into account the 2.25 seconds of free fall, then I would expect to see evidence that those columns are already fractured. That's the only way I can see free fall being possible.
Bah. I'm done with Armchair Engineer's bald assertions about what's ordinary in a CD yet extraordinary in a fire-induced collapse.What exactly is there to explain? Controlled demolitions are not 100% free fall operations.
Where were the charges place? What type were they? Seriously man, there are other people of your ilk that are asking more interesting questions. The collapse of the east penthouse isn't all that out of the ordinary. Again, in controlled demolitions certain sections can lead global collapse. There are a lot of factors involved. And typically, controlled demolitions are not used on buildings that are already on fire and damaged. Again, there's too much chaos to know exactly what happened and why, particularly since we can't see inside the building.
Well, you should at least consider controlled demolition. I've certainly considered a fire-induced collapse. That's called being open minded and thinking critically, something you seem opposed to. We're talking about one column failing and leading to a global collapse in a virtual (and partially actual) free fall. Do you see no red flags there? WTC 7 had 80+ industrial steel columns, and the building fell like a house of cards. I'm really shocked that people aren't at least curious.
I'll also point out that NIST doesn't actually explain free fall, they simple measure and record it.

You really are trying hard to be ignorant, I tell ya.

We have. It doesn't fit the evidence.Well, you should at least consider controlled demolition.
Excuse me. If you were thinking critically you'd realize, very quickly, that the complete absence of direct evidence of high explosives rules out CD.That's called being open minded and thinking critically, something you seem opposed to.
Incorrect. The roughly 14-18s for the collapse is nowhere near freefall. If you refuse to correct your massive errors, you will continue to come to erroneous conclusions. Yes, I see red flags.We're talking about one column failing and leading to a global collapse in a virtual (and partially actual) free fall.
You conclude with a glaring strawman. Of course we're curious. Do you have any idea how inaccurate most of your thinking is?I'm really shocked that people aren't at least curious.
False. They do clearly explain it. Please don't lie about the NIST reports.I'll also point out that NIST doesn't actually explain free fall, they simple measure and record it.
