You mean like the first time in history two passenger airliners were used as missiles to strike the tallest structures in New York City. You mean like the first time in modern human history the explosion of a comet 5 miles in earth's atmosphere is observed via seismic and after effects 100 years ago (Tungunska [sp?]? How do you think they determined the trajectory of that comet without having seen it? OH! They simulated it!
You truthers seem to love using he "1st time in history canard" for every one of your arguments. Tell me something tiger... are you implying that steel cannot weaken in any kind of fire? Are you implying that heat does not cause materials, steel included, to expand and contract under thermal changes? Are you implying that long spanning beams can indefinitely withstand the combination of thermal expansion, contraction and creep stresses? Do you somehow expect connections for these structural members to be over designed to the point of invincibility?
By implying that fire cannot possibly cause a steel structure to collapse you also imply that the material properties of steel are unproven. Are you prepared to defend such a stance roundhead?
Will you
ever give me a building to reference that is either the same material, Structural system, height (similar).
Will you also ever provide a convincing example that suffered the same impact damage, had primary and secondary means of fire fighting impeded?
Your "1st time in history" canard has a lot of implications. You do not understand the difference between credibility premise and conclusion. You launch ad hominem attacks on NIST. There's no convincing you, afterall NIST are a government organization and you and other CT'ists work based on the assumption that the entire government, and all of it's institutions are either in on the conspiracy or have been intimidated to comply.
Thank goodness good science and logic speaks for itself, the truth movement does not have the capacity for it.
Congratulations
what do airplanes have to do with wtc7?...You need to do some elementary reading.
And yes, i dont believe the govt about 9/11. It obviously makes me a whole lot smarter than most on this site. Why, you say, because you parrots slurp up this fantasy, i dont.
The Nist report is a nothing more than an official template laid over the actual observed events. Problem is, nothing lines up.
1. Steel that could well have provided enough information to draw a conclusion that is honest and forthright was removed from the site, which itself borders on criminal behavior, if in fact it isnt . This one little detail makes the investigation a farce.
2. No testing was done to see if CD fit obserrved events.
3. No mention nor attention was paid to temps not consistant with office fires being noted under the building.
4.The explanation given was without parallel, and completely unknown to the prior universe.
The collapse was sudden, shows many striking similarities to a CD,yet even with these numerous similarities, Nist, rather than spend any real brainpower in checking them out, instead states THEY have no record of noise of the magnitude to have been a CD. Yet they apparently did not test to confirm what noise would be generated with various types of CD that could have been used, as a basis for this absurd assumption.
They make the wild assertion that 100 pounds of devices couldnt have been carried in the building.
They state thermite wouldnt have stuck to a column, yet do no tests to confirm this.
In short, they claim as fact an event which has never before happened, throw out any other events as cause that have in fact happened, and provide no data or tests results on how they came to dismiss these other possibilities.
And then Sunder after stating, and i paraphrase that this is what we would expect would happen with this type of failure, answers a question"how would you know what to expect as it never has happened before" with some mumbo jumbo that a 2nd grader would laugh at.
To sum it up, the Nist spent three years trying to put a square peg in a round hole, and the illfitment is now in the public domain.
