Different building, same perimeter pattern.



Detailed study of the mysterious west perimeter wall.

The infamous east face of WTC2.

Collapse initiation ejections recorded and the beginnings of quite an interesting theory of how and where the perimeter was severed into upper and lower sheets.

Odd. A note for the astute observer.


In the link in the first post in this thread, of the WTC2 west perimeter action, can anyone identify the object seen ejected at the earliest moments of the collapse which I mark with a red oval through the series of photos?

Is it just a perimeter section? Are you sure?



Really odd. I need some feedback before I identify it because it is too strange even for me to accept what I think it is.

It seems to be a section of the mechanical floor region ejected violently just ahead of the lowest falling debris. I would 'guess' that it is a section from the 'middle' of the mechanical floor region. It is darker in colour than the rest of the debris, which may also imply that it could be a section of the core, but I really can't be sure.

Your opinion on these matters is always backed up with much personal investigation, so I don't think you should be concerned about stating what you think it may be.

To make myself blatant, I could easily be wrong, but it looks like a large chunk of the perimeter mechanical floor section blasted out at great speed well in advance of the primary 'crushing' mass. If not a section of the external mechanical floor region, then a section of the mechanical floor core, still ejected violently in advance of the descending 'crushing' mass.

Good guess, femr2. I was thinking of a different attribute but I'll show you in an upcoming post that half the mechanical floor perimeter along the W side was found speared unto the earth intact right where the trajectory of the piece marked in red suggests. (not to be confused with the half of the mechanical room perimeter found speared into the earth on the east side discussed in the next few posts).



Anyway, in the link below I show that a section of the N wall remained standing and it's original location is quite interesting.

I want to emphasize that I've already shown (indirectly but quite certainly) that the east and north facades of WTC2 split from one another along 2 specific vertical spandrel bolt lines along the NE corner.

We already know which specific bolt lines they are. How?

The combination of the link in the post before this (NE corner standing linked just above) combined with the rewritten version of "WTC2 E face peels intact" at the link below.

Whether you think the collapse happened naturally or via demo, the reader must admit the NE corner bolt failure straight down the building is very important to explain the dynamics of the collapse and resulting rubble.

Ain't no doubt about this one.

Two posts ago I showed that the top of the portion of the N perimeter wall which temporarily remained standing was right where we saw a molten, glowing something coming from the NE corner moments earlier.

Xenomorph911 recently uploaded some of the best close-ups of the glowing substance I have ever seen below

Notice there is a point source of a bright whitish light just behind the glowing substance deeper within the building. The light varies in intensity and becomes very bright for a moment at 0:37 into the clip.

In addition, check out the strange ejection (which I've never seen before) at 1:15 into the clip which comes from much lower in the building before the collapse, independent of everything else. What the hell was that?


Remember in the last few posts I've tried to show there is strong evidence that there was a vertical seam down the NE corner bolt lines along which the perimeter split during collapse. The strange ejection comes out from about 4 columns in from the corner, the location of another spandrel bolt connection.

From the POV of MIHOP and demo, there is good reason to look for subtle attacks to the spandrel bolts right along the NE corner either on the N or E sides of the building.

During collapse near the end of the clip we see floor-by-floor type ejections moving down the SE corner quite visibly.

Good clip.

My contention for some time now has been that the evidence is showing that heat weakening with incendiaries was used for initiation and that once debris had free fallen outside and the collapse was underway, explosives were used for reliability. The speed of collapse seems to have been kept to about 70% of gravity to allow the outside debris to screen the explosives from view. Of course, the targets would have been the outer core columns and the corners of the perimeters. The spandrel connections closest to the corners would have been the target there. The downside of this, for the perpetrators, is that corners don't get enveloped with debris as quickly as the sides and the corner ejections are visible early in the collapse. The initiation incendiaries, at the damaged NE corner, also seemed to have caused a problem by being visible due to the damage.

We belive that the elements of the core reached the ground in freefall (based on seismic data and the ejections)

and the NE corner event seems to be caused by dislodged thermite device which was placed in the core area

Appears to be a highly exothermic reaction traversing the space between two external columns to me.

Earlier I asked:

I thought it strange because the object is oriented unlike the other perimeter pieces I have observed.

It looks as if it is two separate components connected, the components being perpendicular to each other.

My impression is that it is a piece of perimeter with a floor pan attached.

If it is, Yipes!

The piece marked in red is where I suspect flooring is attached to a piece of perimeter.

The evolution of the piece falling is at the link in the post before this one.


It comes out (like a bat directly out of hell) from the west face between the red lines in the images below.





The photos of the fall show it started with considerable westward velocity (it it shot away from the west wall) and had very little rotational speed (therefore cannot be confused with a rotating perimeter section).

Everything about it (shape, orientation, angular velocity) suggests flooring strongly attached to a perimeter section.


A special, extra strong type of flooring.


The image below shows how far this piece fell away from the west wall compared with the other falling objects (it is marked in red).



it received quite an initial kick.

This is just after the cap begins to descend.
Pretty much the full width of the tower.
An enourmous section of the facade. (East face)

Note the disparity between the line along which initiation begins and the clean perimeter section outline of the ejected section.

The video also contains a couple of clips with views of the WTC2 core.

Femr, exactly.

The top of the peeling section can, for the most part, be known with remarkable precision.

Note the horizontal perimeter seam which I predict.



Points of interest:

1) Notice how the zig-zag line is shaped differently depending on whether it is on the left side or the right side of the face.

2) Notice that this shape has 6 peaks, 3 on each side.

3) The shape of the middlle portion is floor dependent. The whole pattern does not repeat itself every floor. It repeats itself every 3 floors (more in this case because the mechanical room floors are just below, interupting the pattern).


With this info let's re-examine your GIF images above. If you look carefully all 6 peaks are visible. Only my edge piece seems different than the GIF.


This idea is confirmed by photos of the debris. How?

I located the very columns which you see in the GIF. I show how they were found in the rubble at the link below.

Which brings us to a great question: Did we not see the east perimeter bend inwards and buckle just a few floors above? Why is there such a clean, unbuckled cut along bolt lines in the GIF animation above?


To this I answer: Yes, you saw the perimeter beld inwards but, no, you did not see the columns buckle.

This is what we actually see...

1) The perimeter bends inwards
2) If you look carefully you can see the bending slow down as if reversing itself just before being covered by smoke. The bending doesn't intensify, it slows down.
3) The scene becomes covered with smoke as forceful ejections shoot outwards


I have never seen the actual buckling, only the inward belding.

There is another reason to question whether buckling ever occurs. A perimeter section just around the NE corner on the N face remains standing after the upper block passes. The top of the piece was one floor below where we saw the molten stuff pouring out. This is covered below.

http://www.sharpprintinginc.com/911/index.php?module=pagemaster&PAGE_user_op=view_page&PAGE_id=119&MMN_position=259:259


The whole upper block falls and yet doesn't pull this fragile piece of perimeter which, located just a floor below from where the upper block split, stands motionless and unbuckled?


You see, it is more complicated than some buckling, pull-in mechanism.

This Femr gif is applicable to this thread and could open doors in your mind.





An intellectual challenge to all:

Nobody yet to my knowledge has been able to explain the inward pull-in of perimeter columns on the E face of WTC2 during the earliest moments of collapse initiation.

NIST has claimed sagging of floors pulling in the perimeter but, honestly, I put that on the level of the Judy Wood space beam theory.

I confess I have never been able to take it seriously enough to ponder.


Please feel free to submit yur own explanation, even if it is just an improved variation of the one I provide. I propose an alternative explanation for the movement seen above:


The complex movement as seen in the gif above and the inward bending of E face perimeter columns can be explained by modeling the hinge as occurring around two independent axis.


The basic principle demonstrated:




The yellow dot represents the approximate pivot axis of the upper block taken as a whole.


The red line is the east wall (or at least the NE corner) between fl 80 and the NE corner kink and flash.

The red line falls and rotates as shown. This trajectory is verifiable.

The pink curve carves out the lower edge of the red line as it falls.

"r" remains constant during the rotation, meaning the red piece pivots around the green line.


Please note the idea of 2 independent axis of rotation: The red line (section of the NE corner and probably the E face) rotates around the green axis while the upper block in general rotates around the yellow axis.



The yellow line represents the 1000 row core columns (on which the green pivot point rests). The orange lines are the mechanical floor borders.


What this model means is that the flooring between the 1000 columns and the E perimeter did not "sag" and did not rip away from either core or perimeter: It stayed firmly attached and actually provided the pivot "r". r= about 60 ft.



This model seems to work if the WTC2 lean is initiated to the east by severing 1000 (and 900?) row columns not at floor 80, but about at floor 83 or 86.


Why would someone cut 1000 row columns at floor 83, 86 instead of floor 80? Because that flooring represents "r". Those few slabs of flooring provide both the pivot around the green dot and the E face perimeter pull-in force.


Please just think about it. I've got a mountain of material on this subject so I'd like to present it in the proper order over the next few days.
