60% of Americans in one servey think the government did it.....even though there is NO sold evidence.
And what survey would that be? Source please.
Damnit Keyser! You're always stealing my thunder!!

Just do a little research and you'll get why people question the government story . Many are saying that jet fuels and office fires can't melt steel as to make a building fall into it's own foot print near free fall speeds . There's a group of Architechs and Engineers raising most of the questions and challenging the NIST annalysis which if I remember correctly did not say for certain that their conclusions were correct .
Heathen,
Ask yourself why a blacksmith heats metal up before forming it. The answer is because it is easier to form hot metal. I am an engineer, I work on high temperature tools for the oil and gas industry. Believe me things don't have to get very hot before you have to consider using exotic materials (i.e. not the kind of materials used in the construction industry), 200°C is enough to warrant changing the design and material specification. Steel has a very complex microstructure that is hugely affected by temperature, it is the reason it is so versatile as a material.
If you think of the amount of energy required to bend a steel beam, if you heat that beam you are applying a huge amount of energy directly to the material. That heat energy reduces the amount of energy needed to bend the beam. You don't need to melt steel to cause catastrophic failure.
If you want a sensible answer to why steel fails at even quite low temperatures you need to talk to someone who specialises in that type of engineering.

That works fine if you're making horseshoes, but we're talking about the demolition of a 47-story steel framed building. You would need to heat ALL the beams on EVERY floor in a very specific sequence, otherwise the building either falls sideways or the collapse will not be complete (google "Failed Controlled-Demolitions" and watch some videos).
Seriously dude, I think you should go find your erector set up in the attic and remind yourself about reality, because you're swimming in Kool-Aid.

ProdigalSon,
Seriously? I am a mechanical engineer working in engineering specifically on high temperature tools and you are trying to tell me that you know exactly how materials work at elevated temperature because you played with toys?
But just to pander to your idiotic drivel, the effects of heat on steel is the same whatever you use it for, it loses strength.
Why would you need to heat all the beams on every floor in a specific sequence? That hasn't been my experience, that every part has to fail at once, generally one part failing can be sufficient to trigger the failure of surrounding parts due to sudden shock loading. What has this got to do with the fact that steel loses strength at high temperatures?
Watch some youtube videos? No, thanks I will stick to using actual facts to form my opinions, you know those pesky things they have in textbooks and that pop up from actual empirical data.
Kool-aid? What I have stated is based on what I have studied and learnt at university and in a job where I am paid to tell people how materials act at temperature. What exactly is your qualification? Toys and youtube? What a maroon.

Holy crud, you don't know the first thing about taking down a building. Who the hell needs controlled demolition companies then? Just light a match and wait for the magic show......

High temperatures? From an office fire? On two floors? Brought the building down, not counting the initial penthouse collapse, in 6.9 seconds into its own footprint? Yes, that's some serious Kool-Aid. This is steel frame construction, with real steel girders, not corn flakes mixed with steel powder. I don't have to be a construction engineer to see that. In your world, a 2.0 rumble would bring down New York CIty into its own footprint.
Check out the Windsor fire in Madrid that burned like a Roman Candle for more than 20 hours, with the twisted frame still supporting a contruction crane after the fire was out..... Oh, you don't watch videos, that's right..... you already know everything....

So that would be no qualifications then. What a surprise.

Well the only reference to this subject on Google about 60% is this thread. 60% believe it was a conspiracy? No freaken way.
