But in this case it is well documented that the buildings were closed from the 50th floor up for the weekend prior to 911 for "cabling upgrades" and the security people said that there were an army of engineers going in and out of the building for 36 hours.

care to show a valid source for that silly claim....
FORBES, Scott
Senior Database Administrator, Fiduciary Trust.
He has details on how the twin towers were rigged:
Did the World Trade Center towers undergo a deliberate „power-down” on the weekend prior to the 9-11 terrorist attacks? According to Scott Forbes, a senior database administrator for Fiduciary Trust, Inc. – a high-net investment bank which was later acquired by Franklin Templeton – this is precisely what took place. Forbes, who was hired by Fiduciary in 1999 and is now stationed at a U.K. branch office, was working on the weekend of September 8-9, 2001, and said that his company was given three weeks advance notice that New York’s Port Authority would take out power in the South Tower from the 48th floor up. The reason: the Port Authority was performing a cabling upgrade to increase the WTC’s computer bandwidth.
Forbes stated that Fiduciary Trust was one of the WTC’s first occupants after it was erected, and that a „power-down” had never been initiated prior to this occasion. He also stated that his company put forth a huge investment in time and resources to take down their computer systems due to the deliberate power outage. This process, Forbes recalled, began early Saturday morning (September 8th) and continued until mid-Sunday afternoon (September 9th) – approximately 30 hours. As a result of having its electricity cut, the WTC’s security cameras were rendered inoperative, as were its I.D. systems, and elevators to the upper floors.
Forbes did stress, though, that there was power to the WTC’s lower floors, and that there were plenty of engineers going in-and-out of the WTC who had free access throughout the building due to its security system being knocked out. In an e-mail to journalist John Kaminski, author of The Day America Died (Sisyphus Press) and America’s Autopsy Report (Dandelion Books), Forbes wrote: „Without power there were no security cameras, no security locks on doors, and many, many ‘engineers’ coming in and out of the tower.”
Forbes didn’t think much of these occurrences at the time, and said that he worked until Monday morning (September 10th) to get all the computer systems back online. Due to his IT-related duties on Saturday & Sunday, Forbes had Tuesday, September 11th off, and thus watched the World Trade Center towers collapse from his apartment. While doing so, he recalled, „I was convinced immediately that something was happening related to the weekend work.”
In addition, Forbes says there were other peculiarities revolving around this unreported event, including:
1) Fiduciary employees trapped between the 90-97th floors of the South Tower told family members (via cell-phone calls) that they were hearing „bomb-like explosions” throughout the towers.
2) Video cameras positioned atop the World Trade Center which were used to feed daily images to local television stations were inexplicably inoperative that morning.
3) A Fiduciary employee who was on one of the lower floors and escaped immediately after the first (North) tower was struck, reported that he was amazed by the large number of FBI agents that were already on the streets surrounding the WTC complex only minutes after the initial strike.
4) Last but not least, Ann Tatlock, CEO of Fiduciary Trust and now a board member of Franklin Templeton, had just arrived at a conference hosted by Warren Buffet at the Offutt Air Force Base (home of the U.S. Strategic Command Headquarters in Omaha, Nebraska) when the 9-11 attacks took place. Coincidentally, later that day President George W. Bush flew into this very same base on Air Force One for „security reasons.” Even more chilling are the Offutt AFB ties to the CIA’s MK ULTRA experiments, Project Monarch, the Franklin Cover-Up, and the diabolical practices of Michael Aquino. (Type any of these words into a search engine for more information.)
In the end, Forbes says that even though these disclosures could jeopardize his current employment, he has stepped forward because, „I have mailed this information to many people, including the 9/11 Commission, but no one seems to be registering these facts.”

YET again you avoid the question psikeyhackr why WONT you look at a possible dynamic load calculation I mean you admit your model is not an exact representation of what happened but you went out your way to promote that.

Do you believe there was a power down on the 48th floor up at one of the towers? Make an attempt at thinking before you answer that.

Yes. But heated core columns underwent thermal creep - iow, shortened - and transferred some of their loads onto those ext columns. plus, the ext columns were heated, making them weaker. Plus, the bowing wasover several stories - which, when we do some research about buckling lengths and how they get exponentially weaker as the buckling length increases, we put this all together and learn that:
How do you know the core columns were heated to anywhere near failure? That is just an assumption. I know for a fact that one hour of hydrocarbon fire would not cause the massive core box columns to fail. That is just nonsense, but of course you need to believe that don't you?
How would the columns shorten when heated? Heating causes expansion mate. Thermal creep? Citation needed. Please explain thermal creep.

Are they saying that was the stiffness on every level of the WTC?
How did they adjust for the upper portion being crushed due to Newton's 3rd Law?

How much does it need to be adjusted for? Have you calculated that the resistance of a floor is more than the energy of the falling mass?

I have never seen a specification of the amount of energy required to break a truss connection. So doing calculations on the basis of grossly inadequate data is stupid. People just select numbers to justify what they have decided to believe and ignore factors that do not support their position.
Drop some rice on one scale. Whoopee! Get 5 scales and stack them. Drop the rice on the top scale and see how much it affects each scale.

So you're talking out of your ass then. Your assertion that the collapse should have arrested is based on your imagination alone, not data or science. Stop making stuff up, psikey.
Edit: And just so we're clear, your scale analogy is just plain dumb. There was SPACE in-between each floor in the towers. That means that after each bit of truss resistance is overcome, there is 12 feet of space for the debris to accelerate more and impact the next floor. Your analogy allows for ZERO acceleration after impact, thus it is stupid and wrong.

I notice you said nothing about FLOOR versus LEVEL.
You said nothing about the energy required to break a truss connections.
The distance was 12 feet from the surface of one FLOOR to the surface of the next FLOOR.
The trusses were almost 2 feet tall so there was only 10 feet of empty space between the floors when they were UNOCCUPIED. Occupied floors would have had walls and cubicles and furniture. That would add weight but it would also absorb energy in any supposed collapse.
The CORE was not just empty space. The columns extended the entire height.
And even with empty space and no breakage required my Python model takes 12 seconds. Breaking connections at each FLOOR would absorb energy and slow things down. So how could the north tower come down in less than 26 seconds?

Floor vs level is irrelevant. I'll agree about the 10 feet, but again, that's 10 feet of acceleration. Cubicles really do not add hardly any resistance, and even if they added a ton, it's still five feet or so of constant acceleration. That's added kinetic energy no matter what you try to say. Since the floor connection clearly broke instantly, as seen from the videos, I'm inclined to say that there was still extra energy from the initial fall, meaning that after the first floor broke, the falling mass had MORE energy than it had to break the first floor. What could possibly slow it down?
