OOS Collapse Propagation Model

[BasqueArch]

..........
The 75th floor ejection comes out aligned with a hallway. Notice we see nothing emerge out of the known air vent locations around the 75th and 76th fls, instead we see an ejection emerge from a place with no air vents and which lines up with the center hallway.
We know where the air intakes and exhaust openings are located. Nothing emerges from them. Mr 75th fl ejection chose to take an elevator shaft also, turned north and shoot out of a window lining up with the hallway to the central core.

Rough OM. Air handling units for 32 floors (59-74,76-91) x 42,000 SF/floor x 32 floors = 1,344,000 SF at say 1 CFM/SF air handlers fan x say 10% Fresh air return supply = FA ducts designed for 134,000 net CFM (cubic feet per minute) fresh air supply at floor 75.

Upper floors collapsing in 1/8 th second = 42,000 SF x 11.66 feet height x (rate) 8 x 60 sec per minute = 235,066,000 CFM / design ducts 134,000 CFM = Actual CFM compressed by the collapse of one floor above = 1,754 times greater than design capacity of the metal ducts (and joints).

From this, other vertical shafts (like stairs,elevators,others) should be deducted but frankly I’m not doing it. The FA ducts burst or were crushed before delivering this overpressure to the 75th mechanical floor plenums at the perimeter walls.

Another math-free failed claim by the Conspiracists.

...Another math-free failed claim by the Conspiracists.

Whilst I am tempted to agree logic says I should not.

Where is Major_Tom's claim?

It is his OP about the "OOS Collapse Propagation Method" which I agree with in general with or without M_T's label. But all we see from M-T is a series of open ended questions or comments simply hanging there.

I don't think he has made a claim. So AFAICS there is no claim to fail.

Yet????

How about you make a claim M_T rather than posting half an assertion?

MT made a no-claim, which I no-debunked.

 

[Major_Tom]

My claim is simple: You cannot explain many of these ejections though the ROOSD process.

COnsider this extreme example:

I call this particular ejection "Speedy Gonzalez" because it emerges about 40 floors below the collapse front very early into the collapse of WTC2. A bit later...

While at the same time from the northeast:

...

Your claim is very simple, you think it was an inside job, you can't grasp a gravity collapse, but your photos prove it. Just think, after 9 years you could of had a PhD in structural engineering, but you make up fake "studies" and try to back in an inside job delusion. Maybe not, some people can't do the math required to be an engineer.

You make up your own study to show a gravity collapse is possible, then you make up implications to back in your inside job nonsense using your failed study with no goal, no conclusions.

The first posts you made at JREF presented evidence against an inside job, and you had no clue you debunked thermite and explosives.

What is your inside job?

 

[Major_Tom]

According to the ROODS concept, whether employed naturally or intentionally, the activity around MER floors is pretty important. These are natural discontinuties in the ROOSD process.

Notice that there are no ejections in the areas with known air ventalation openings.

The ejection along the north face off the NE corner have no natural explanation. There are no vents in the corners.

Assuming the 75th fl layout is the same as fl 41.

On the east west side of the north face the same thing is happening. Observe:

It is obvious that something is happening to the interior of fl 41 that cannot be attributed to venting or elevators.

43, 41 MER activity visible from the south also:

My claim is simple: You cannot explain many of these ejections though the ROOSD process...

(My emphasis)
Whether I can explain it or not is not relevant.

You are presenting this evidence as part of your claim. The onus is on you to show where these ejections fit into your claim. You have not done so at this stage and you persist in attempting to pass the burden of proof. I am unlikely to fall for the ploy whether tried by you or tried against you.

For my purposes I am satisfied that the "global collapse" occurred by a mechanism of the style you claim as your own by labeling it "ROOSD". I have never given my version a title and I have no need to explain this miscellany of spurts and farts. They are expected in such a dramatic collapse and there is no need for me to explain them for my purposes. Remember my focus is assist lay persons to understand the engineering reasons why demolition was not required and also to explain to genuine sceptics the overwhelming evidence that there was no demolition

If you have a need to know every detail I suggest that you are bound to be disappointed - few if any such details will ever be known.

Whether the discontinuities are of any significance remains a separate question.

...The ejection along the north face off the NE corner have[sic] no natural explanation. There are no vents in the corners...

(My emphasis)
A strong claim. Don't you mean that you cannot explain it?

...On the east west side of the north face the same thing is happening.....It is obvious that something is happening to the interior of fl 41...

..yes..

that cannot be attributed to venting or elevators...

Overbidding your hand again Major_Tom. I won't fall for it. I doubt that few others would.

Why don't you tighten up your logic?

Suggestions:
1) Try completing your claims rather than half presenting them;
2) Drop the leading questions and other ploys which attempt to pass the burden of proof to me and others who care to respond.; AND
3) Desist from the habit of claiming more than your evidence or logic supports.

 

[pgimeno]

The ejection along the north face off the NE corner have no natural explanation.

That's a claim from personal ignorance, very similar (not to say identical) to those in the paranormal world: "I don't know the explanation, therefore it has no natural explanation, therefore it's paranormal [or artificial, in this case]."

Like those, it is rooted in the arrogance of thinking "if I don't know the answer, then there's no answer."

 

[TruthersLie]

Well you do know what they say.
Once you go squibs you definately need a bib.


ETA: edited to make it rhyme..

 

[Myriad]

ROOSD is the only known propagation mechanism which agrees with all observables.

My claim is simple: You cannot explain many of these ejections though the ROOSD process.

Please clarify. Which of these claims do you / did you not really mean? Or are the ejections not observable?

Respectfully,

There's testimony of the overpressure too. Many firemen reported being lifted off of their feet and thrown by the winds generated by the collapse of the South Tower (IIRC).

Can anyone tell what that big black rectangular thing is attached to the back of the falling perimeter column section in this image?

Isn't that a floor slab?

 

[Major_Tom]

Here is a photo of the same falling piece taken a bit earlier:

There are two large sections of MER perimeter from the 75th through 77th fls. The thing that looks like a floor slab is behind the lower of the two MER perimeter sections.

If that big rectangular thing attached to the back of the MER perimeter is flooring, then it is the 75th fl beam flooring from the south side of the west slab.

Here is a close-up of it:

Notice it is 18 columns wide and the last 6 columns on the right end are angled away from the viewer. The other 12 columns remain in a straight line.

 

[Major_Tom]

Notice how the slab fits in a diagram of the beam flooring:

The three edges marked seem to fit into the corner of the flooring.

The portion of the slab that was connected to the core is in the blue oval. The portions of the floor in the purple and green ovals seems to be ripped along the edges.



The features correspond to a slab location in yellow:

The three edges fit well with the observed ripping.

The perimeter pieces marked in dark and light blue are the MER perimeter piece you can see. The pink perimeter to the left corresponds to the other falling MER perimeter piece seen falling next to the first.

The 6 columns in light blue would be the ones that are bent away from the camera in the original image. Notice how it lines up perfectly with the short beams in the corner.

The slab would be from the 75th floor.

 

[funk de fino]

No one cares. It is irrelevant.

 

[Major_Tom]

That is fine. You keep not caring and I'll keep posting.

I'd prefer less noise in my threads, anyway, so it works out well for all of us.

 

[Major_Tom]

Obviously a 60 ft by 50 ft intact beam floor slab falling from the 75th floor doesn't make much sense from the point of view of OOS propagation.

Notice the location of the green oval:

Now please notice the location of the mysterious ejections along the 41st floor:

North face from the east:

and a twin set of mystery ejectioms from the west:

It is strange the way they are in the exact same locations on the 41st fl mechanical floor as the rip shown in the green oval from the 75th mechanical floor.



What a coincidence!

Even more interesting are the connections in the blue oval.

Somehow this beam floor slab broke itself free of the connection to the core and managed to "jump" out the side of the building still intact

Maybe the beam flooring panicked and jumped?

 

[Myriad]

ROOSD is the only known propagation mechanism which agrees with all observables.

Obviously a 60 ft by 50 ft intact beam floor slab falling from the 75th floor doesn't make much sense from the point of view of OOS propagation.

Okay, so is this yet another observable that does not agree with the mechanism that agrees with all observables?

Your line of argument is growing increasingly incoherent.

Respectfully,
Myriad

 

[Major_Tom]

60 ft of beam flooring from the 75th fl jumps out of the building intact. Wake up, guys.
