Another video that was in the related videos link shows that stuff was glowing far down its fall from the building. THEY claim this is because it was molten iron. That would not be the case. Iron does not hold heat well, and would stop glowing after a few dozen feet. Burning plastic, however, would keep glowing until it ran out of fuel and stopped burning.

The steel melted AFTER the towers collapsed, because of the insulating effects of the rubble containing the heat of the fires which kept burning for more than 24 hours after.

I realize that sounds counterintuitive, but it is the same reason that piles of damp straw can catch fire due to decay. The organisms that cause the decay cannot withstand the temperatures which would cause the straw to burn, but the heat continues to build from the fringes because it can’t escape fast enough, and the straw catches fire.

“A lot of eyebrows were raised,” We Are Change reporters point out in summary, because many saw it as a clear controlled demolition, including a number of engineers. Hayton responded, pointing out that he was not aware of the situation with WTC 7. “This sounds so significant– I’m just amazed I didn’t know about this… This is completely news to me.”

“So, is there no official explanation?” Hayton further probed.

We Are Change continues to explain the delayed NIST report on WTC 7 as well as the response from a BBC editor who claimed 9/11 tapes were “lost” in a ‘cock-up.’

“I sense that you think there’s a conspiracy here– but you might be right,” Hayton concluded

About 1:25 here you can see it SPEWING OUT of the building.

Also, where is the plane that “hit the pentagon?”

Is this a plane?

How wide was the debris field in Shanksville?

There is just WAAAAY too much evidence against the official story guys.

Oh, and noone wants to even think about why the BBC reported the collapse early. I have NEVER heard ANYONE try to come up with an excuse for that.

Thanks for the informative link.

THE WAR ON TERROR IS A TOTAL FRAUD.

DONT MESS WITH THE TRUTH MOVEMENT , ASK MARK DAVIS

KAPISH ?

If you actually pay attention to the video, debris thrown out horizontally from the floors being collapsed on fell faster than the building.

“…had their steel UL certified for temperatures well over 2000F for hours.”

Except that all the reports have concluded that the insulation, which was required for that certification, was blown off in the blast from the collision, which invalidates the certification.

Thermate, eh? Sorry, Sulphur is not an unexpected chemical for the rubble. Here is one response to that claim.

By the way, this information is not actually meant for Karen, since I don’t expect to penetrate the shield of misinformation she has surrounded herself with, but for those who might begin to be swayed by the sheer volume of crap overwhelming them.

Yes. Since you’re tossing around terms from physics, here’s one for you:

Ever hear of something called “impulse”? This can be defined as a change in momentum, usually a very abrupt change… like when the upper floors of a building collapse onto the structure below it. The total mass supported by the lower structure hasn’t changed, but the momentum has suddenly changed tremendously. This can be explained by the conservation of energy: there is a large amount of potential energy stored in the supported mass of the upper floors of the building. When the supports fail, the potential energy is suddenly converted to kinetic energy.

Oh, one more thing: steel doesn’t have to melt to lose its structural strength. This is why blacksmiths can bend and shape steel parts that are at temperatures well below the melting point of the metal. This is also why fire codes require structural steel in buildings to be insulated against fire: fire marshalls, architects, civil engineers, and others concerned with the safe construction of buildings know (unlike Troofers) that steel buildings can certainly collapse due to fire.

Designing a building to ensure a determined level of fire safety is a comprehensive issue requiring the consideration of some related factors, such as the building type, the area and height of the building, located fire exits, the number of occupants, and the quantity and type of combustible materials (potential fire load) expected to be present in the building. It is also very important to consider the fire spread between attached buildings or building parts which can be used for different purposes. As mentioned previously, a steel building’s structural members are expected to have fire resistance to prevent any structural failure for a determined period of time, as stated by the related fire codes, to give the building occupants more time to escape and allow the fire service to control it. The required fire resistance periods for the different steel building types can be easily found in country-specific building codes.

On the other hand it must be kept in mind that, steel building members may easily collapse during a fire if the temperature is allowed to reach a critical value. The fire resistance of a steel member is related to some important factors including the section size, the perimeter of the section exposed to fire, place of the member in the protective structural assembly and the steel material thickness. Depending upon structural assembly and the fire occurrence, even the exposed steel may resist fire up to 30 minutes. However the structural steel needs to be protected against fire using the proper insulating materials and methods to control the situation and resist for longer periods. In essence the structure’s fire safety is measured by the time of resistance regarding the supplied evacuation time and the level of failure. It also is important to assure that the fire resistance time is sufficient as such that the structure is able to carry the building loads during the duration of the fire. [emphasis mine]

As previously mentioned, steel loses strength and stiffness at high temperature levels just like any other building materials. Although the effective yield stress for design purposes, generally is taken as zero at 1200 0C, in actuality the yield value does not fall to zero unless the steel reaches its melting point, 1550 0C. This melting point hardly will be reached in building fires. Although the steel is a non-combustible material itself, it has a high heat conducting value, which adversely affects the structural performance during a fire exposure. That is why it is important to create a fire design for the steel buildings. [emphasis mine]
