Wow, your really upset. Can you tell me what aspect a mechanical engineer would have building a sky scraper? Tell you what, next big job I get I'll call you when I want someone to tell me how to pump the water. K buds

The only one I see getting upset is you. In quite an embarrassing, uninformed, and ignorant manner I might add. Maybe that kid in your picture can teach you how to be more mature.
Shortly after lunch, some workers observed slab deflections of about 6 inches to 2 feet (150 to 600 mm) for both the 23rd floor slab and the freshly placed 24th floor slab. The freshly placed section of the 24th floor slab then fell onto the 23rd floor slab, starting a collapse that continued all the way to the foundation
The building’s collapse removed the edge support from the parking garage, and falling debris triggered the failure of the garage
Each floor was to be 9 ft (3m) from top of slab to top of slab

This IS NOT A TWO MASS collision that the truth movement believers think, you can't look at the Twin Towers collapse as mass (A) BEING LESS THAN MASS (B).
The floor area is 42,000 sq feet when material fell the part of the structure that would be impacted most would be THE FLOOR SLABS! , that is painfully obvious to anyone with any common sennse, the pancaking did NOT cause the collapse the collapse was initiated by the structural damage and the effects of the fire here is a picture showing the wall BOWING before the collapse.
Bowing Wall
When any mass from above falls on the FLOOR SLAB below ONLY the connections of that slab can try to absorb the DYNAMIC LOAD, the weight of concrete alone on each floor slab would be 800 TONS + , the trusses were supported at both ends by a piece of steel angle seen in this picture below. Those connections were the same for every floor apart from the service floors (3 irrc)
Floor Supports
Some people on here seem to think that if these floors fall some from 1300+ there should be a nice neat pile at the bottom, the concrete was only 4.5 inches thick even neatly stacked 110 x 4.5 inches is only 41.25 feet.
The walls were damaged by the impact so was the core, the walls were designed to take the wind loads , most of the dead load by the cores, the damage and the heat from the fires cause a reduction in load capcity the walls bowed the collapse happened, the the bulk of the load FELL through the floorslab's as each slab was impacted it failed, that reduced the restarint provided to the walls an they peeled away.
If you think a PROGRESSIVE COLLAPSE can't happen well here is another example.
Progreesive Collapse

That 9ft is less than the floor heights for the twin towers the mass is far smaller yet it still fell all the way the the bottom of the structure.
The only thing that stopped the whole structure from falling was each building had a dividing wall and there own floor slabs.
Now think about that!!!

I am not arguing if what you say is possible but what you say didn't really happen as far as I can tell. For one those towers were blowing black smoke, and people were seen standing near the impacted sections trying to get air. Unless the heat your are talking about was somehow localized to the perimeter angle iron and core columns, the fires did not seem to be burning hot at all. But maybe it was somehow hot enough up there since there was molten metal found deep in the debris surviving with very little oxygen. That's weird unless it was a chemical reaction or something.
That picture you have of the building that pancaked... is there a video of that we can all see? I would love pull out my stop-watch on that golden egg.
The Federal Agent, Nuclear Materials Courier Program The National Nuclear Security Administration (NNSA) is responsible, under law, for safeguarding and transporting nuclear weapons, components, and other sensitive nuclear materials between authorized destinations. In fulfilling that responsibility, the NNSA, through the Office of Secure Transportation (OST), employs, trains, and administers a work force of Federal Agents (Nuclear Material Couriers) whose primary responsibility is the safe and secure transport of such materials. Since 1974, OST has been assigned responsibility to develop, operate, and manage a system for the safe and secure transportation of all government-owned, NNSA- controlled special nuclear materials in “strategic” or “significant” quantities. Shipments are trans ported in specially designed equipment and are escorted by armed Agents. The NNSA/OST is looking for highly capable individuals who qualify for Federal Agent positions.

A Secret Service agent was arraigned Tuesday on charges he stole five of the agency's cars recovered from the World Trade Center site. According to a complaint unsealed in Brooklyn Federal Court, William Bennette, 52, has admitted to the theft. He surrendered to federal authorities Tuesday morning and was later released on $$75,000 bond. Bennette, a retired police officer who has worked for the Secret Service since 1999, was ordered to make an inventory of what was left of the agency's fleet of 179 vehicles assigned to the World Trade Center on September 11, 2001. Instead, according to investigators, he combed an auto graveyard in Brooklyn for unscathed cars. Bennette allegedly used forged government documents and receipts to make it look like the cars were sold to an auto repair shop in Brooklyn. He kept one for himself and gave cars to his mother and sister, and an employee of the auto shop got the last two, authorities say. His lawyer said trauma from the World Trade Center attack may have played a factor in Bennette’s actions.
When called in to the Brooklyn field office for questioning on April 2, Mr. Bennette, who joined the Secret Service in 1999 after retiring from the New York Police Department, said he had forged signatures of agency managers to transfer the titles of the cars, the complaint says. At his arraignment yesterday in front of federal Magistrate Steven M. Gold, Mr. Bennette, wearing a black raincoat and a glum expression, said little other than ''Yes, sir'' and ''That is correct, sir.'' He was released after his wife signed a $75,000 bond. If convicted, he could be sentenced to up to 10 years in prison. Outside the courthouse, Mr. Lieberman said that while his client was not trying to minimize the charges, ''There is a personal side to this story that will come out as the case proceeds.'' He did not go into detail but said that Mr. Bennette had spent much of Sept. 11 helping rescue people at 7 World Trade Center before it collapsed at 5:30 p.m. He said that it would be up to mental health professionals to determine what effect the experience had had on Mr. Bennette.

the World Trade Center twin towers were an authorized destination for such material?

what are the two little gray jets coming out just below the impact on the right side of the building? Is that a camera glitch?

Are you saying all the footage supports progressive collapse? You must have seen different footage because ALL of the witness testimony from that morning as well as the footage of the collapse supports explosives. And there are many engineers to have spoken out, check out all the threads on here.
You clearly haven't watched much footage.
Watch a video of any controlled demolition and then watch the close-up videos of the towers collapsing.
In a controlled demolition, the building seems to consume itself from the bottom up. This is done on purpose so the top floors stay intact as they come down, creating a smaller footprint.
The WTC towers collapsed from the top down, starting with the upper most sections above the damaged area coming down onto the floors beneath.
I am not falling for that one. I never stated "controlled demolition" I said explosives. Just because explosives were used does not automatically mean CD. It just means the building was blown up in away we may not have seen before. Stop trying to fit it in a CD models. In fact stop with your models all together. This is real life son.
So your evidence that explosives were used is the fireball being pushed out of the building by the rushing air of the collapse? You're gonna have to come up with something better than that... son (I really wish there was an eye roll smiley for idiotic remarks like yours). In the closeups of the damaged portion, you can see the structure give way just before the fireball is expelled from the building.
This is real life, boy. The theory that explosives were used to collapse the buildings is fantasy and there isn't a single shred of evidence that suggests otherwise. All the truthers have is opinion, speculation, and photos that are easily debunked. Fantastic claims require fantastic evidence.
I will just go with eye-ball witnesses and leave the rest out. Firefighters, police EMT's news anchors... everyone on the morning of 9/11 reported hearing explosions. How does progressive collapse answer to that inconvenient truth.
Hmmm. There were two towers collapsing. They have mass. The movement of said mass may have caused materials to destruct. Have you ever crushed a concrete cube in a lab? Sometimes quiet, usually very noise. Ever tested the tensile strength or compressive strength of steel? Usually noisy. To say everyone heard explosions is wrong. You have hundreds of people experiencing an unprecedented event and you expect them to understand fully what happens. Unlikely.
Then you go tell all the first responders and everyone that survived that what they heard was wrong. They are not going off memory since the testimony I am referring is from the footage on the ground on 9/11.
One quote I can remember from a senior fire fighter "It's like they planned to bring down the building, boom, boom, boom" I'm busy right now but the footage is easy to find if you care.

Okay Kiddies, for the umpteenth time, I'm going to post the Jeff Prager NUKED material for your edification; maybe the OS supporters will actually read it this time, I remain ever hopeful...
Prager NUKED pt 1
Prager NUKED pt 2
You'll see photos you've never seen before, many of them uber-zoomable. You'll have to learn a bit about nuclear physics but he walks you through it. You'll actually know what you're talking about regarding what we saw that day, what the aftermath was like, what the evidence unequivocally showed, and a whole lot more!
Cheerio!
