Conservation of momentum calculations are so complicated. Our computers just can't handle them.

Where'd R.Mackey go?
I guess you missed the section in the report where they mentioned the structural databases. http://wtc.nist.gov/NISTNCSTAR1-2A.pdf (page 29 of the PDF.)
The information you are looking for just might be in that data base. Do a FOIA to NIST for the databases.
What decade are you in?
I guess you missed the part where I said HUMAN READABLE.
The SAP data requires a computer program that costs $2000. If the NIST is going to supply us with a 10,000 page report what should be so difficult about a table with 232 numbers specifying the tons of steel and tons of concrete on every level. How is it they manage not to do a collapse or impact analysis on the basis of that data when by their own admission the distribution of weight information is necessary?
Why do so many people make excuses for the NIST anyway?
Some people say that Gregory Urich's spreadsheet is the best readable data but he admits that his perimeter column data is interpolated. Why should we tolerate interpolated data when $20,000,000 and 3 years were spent on this incident?
Why did they even create a report about suspended ceilings? I only found that because of the search I did for "center of mass". I was expecting them to say something about the center of mass of the tilted top portion of the south tower at the start of the collapse. But NO! They don't mention the center of mass or center of gravity of the top 25% of the building that tilted 20 degrees but somehow did not fall down the side. And these people call themselves "world renowned experts" on building collapses. ROFL

So then your gripe is not that the data isn't there, but that NIST didn't place the particular information you are looking for in the report?
Do you comprehend the difference between DATA and CORRECT DATA that is verifiable? Do you just BELIEVE any obfuscated source of AUTHORITY?
Do you know how much variation there is in the different claims on the quantity of CONCRETE in the towers? The NIST report says "roughly 200,000 tons of steel" in three places, referring to the total of both towers, though they don't say that clearly, but nowhere do they specify the quantity of concrete even that vaguely.
Although there is agreement on about 100,000 tons of steel in the towers even Urich's data looks kind of peculiar in the bottom 12 levels on the distribution. Why should it be difficult for the NIST to tell us the number and weights of each of the 12 types of perimeter wall panels? The only reason we know the heaviest type was 22 tons is because of engineering article from 1970. I haven't even found that in the NIST report. So why are we supposed to trust a 10,000 page report that can't supply something that simple and only uses the term "center of mass" 4 times in one report about ceilings? ROFL Some engineering analysis for "world renowned experts"!

CNN mistakenly issued a report where they assumed it was a cellphone, but the reality is that Olson didn't know. The idea that he's "changed his story" is a distortion of the truth.In various interviews, Olson himself has changed his story from she rang on an airphone to from her cell phone. Often these were interviews shown the same day.
HUME: You don't know whether it was on a regular cell phone or one of those air phones?
OLSON: No, I don't. I first of all assumed that it must have been on the airplane phone, and that she somehow didn't have access to her credit cards. Otherwise, she would have used her cell phone and called me.
HUME: Of course.
OLSON: So I think that was probably what it was. But Barbara got through a second time. And we exchanged the feelings that a husband and wife who are extraordinarily close, as we are, those kind of sentiments. And she assured me everything was going to be OK. I told her in the first conversation that the two hijacked planes had hit the World Trade Center.

KING: How does the second conversation end? OLSON: We are -- we segued back and forth between expressions of feeling for one another and this effort to exchange information. And then the phone went dead. I don't know whether it just got cut off again, because the signals from cell phones coming from airplanes don't work that well, or whether that was the impact with the Pentagon.

The only liar here is David Ray Griffin for knowingly spreading this fiction.The federal government itself presented evidence in a court of law, accordingly,that contradicted Ted Olson's story, regardless of whether the calls were supposedly made from a cell phone or an onboard phone.
So did Ted Olson lie about receiving phone calls from his wife? And why were such contradictions not investigated, but allowed to be included in The Official 9/11 Report?![]()
57. The records available for the phone calls from American 77 do not allow for a determination of which of four “connected calls to unknown numbers” represent the two between Barbara and Ted Olson, although the FBI and DOJ believe that all four represent communications between Barbara Olson and her husband’s office (all family members of the Flight 77 passengers and crew were canvassed to see if they had received any phone calls from the hijacked flight, and only Renee May’s parents and Ted Olson indicated that they had received such calls). The four calls were at 9:15:34 for 1 minute, 42 seconds; 9:20:15 for 4 minutes, 34 seconds; 9:25:48 for 2 minutes, 34 seconds; and 9:30:56 for 4 minutes, 20 seconds.

This is the wrong thread for this, but okay, let's assume that the NIST got it all wrong and nothing they say can be trusted.
So, let's hear your theory, from start to finish, in which you show your work.
But they said it in only one place in their 10,000 pages of rubbish so I presume most people weren't supposed to notice. So why haven't they provided the data in HUMAN READABLE FORM that they admitted was necessary?
I don't know OR CARE what theory you are talking about.
Actually i'm wondering how many pages the NIST report have to be, to explain everything to the layman?
So this isn't actually a point that could support any alternate version of the case.
Which means you're on the wrong thread, as LashL pointed out.
Do you comprehend the difference between DATA and CORRECT DATA that is verifiable? Do you just BELIEVE any obfuscated source of AUTHORITY?
Do you understand that exact numbers (especially in a building construction) will not be exact? Take for instance concrete. You order so many tons of concrete but do you know exactly what was actually used in construction and what was lost or unused in the process?
You will ultimately have to go by the construction plans and accept the fact that that info will only be an estimation.
Although there is agreement on about 100,000 tons of steel in the towers even Urich's data looks kind of peculiar in the bottom 12 levels on the distribution. Why should it be difficult for the NIST to tell us the number and weights of each of the 12 types of perimeter wall panels?

Again that information is more than likely in the database. Do an FOIA.
If you don't particularly like the manner in which they wrote the report why don't you shoot them an e-mail and ask them for the info you are looking for?
I'll wait for the question, but keep in mind that one of the very first things one does when evaluating an unexpected answer is to question the assumptions. Number 2 through 4 all look suspect to me, so be prepared to verify them. This is good practice in general.
One interesting scenario would be for jet fuel to "pool" on or around a large elevator, say the main freight elevator, about the time said elevator had its cables cut by the impact. The fuel would then fall with the elevator at "virtually free-fall" speeds, resulting in a fireball in the sublevels only a few seconds after impact.
I don't know OR CARE what theory you are talking about.
I showed you where the NIST admitted that the distribution of weight of the tower was necessary for the analysis. But they said it in only one place in their 10,000 pages of rubbish so I presume most people weren't supposed to notice. So why haven't they provided the data in HUMAN READABLE FORM that they admitted was necessary?
Get this straight. I don't give a damn about the United States government. I don't give a damn about Islamic terrorists. I don't give a damn about Christianity either.
This is a physics problem barely above grade school level. We don't even know the tons of steel in the impact zones. It is curious that before 9/11 it was said that the towers contained 425,000 cubic yards of concrete. So why can't we learn where that concrete was in the towers SEVEN YEARS after their destruction.

If the plane that hit the south tower was flown by CIA agents with remote controls would that have changed the distribution of steel and concrete in the south tower?
If the plane that hit the south tower was flown by Arab terrorists would that have changed the distribution of steel and concrete in the south tower?
If the plane that hit the south tower was flown by drunken Hell's Angels snorting coke would that have changed the distribution of steel and concrete in the south tower?
Talking about a theory when you don't even have trustworthy data to analyze the supposed gravitational collapse is hilariously absurd. This thread is supposedly about settling something. Trying to settle a physics problem without data that can be trusted to solve the problem is nonsense.
When a moving mass hits a stationary mass of the same size the velocity is cut in half and even though the mass doubles the kinetic energy is cut in half. The top 16 stories of the north tower would be coming down impacting progressively more mass. Bazant is a joke. So talking about this collapse analysis without even insisting on being sure that the data is correct for SEVEN YEARS says some very peculiar things about this nation that put men on the moon. Make a big deal about theories without data. ROFL Pseudo-Intellectual Male Bovine Excrement!
