buildings that have been attacked by missiles suffer severe damage and fire but yet they don't collapse.
i will accept the collapse if there is just one other case of it happening. we're not talking about a spontaneous freak of nature or an action of a person, we're talking about structural damage and fire to a steel building. how many steel structures exist today? how many have suffered similar damage? and finally, how many have collapsed as a result of the damage?
non one can provide an example of this because it's never happened before, yet we're expected to believe that not only did it happen for the first time in history, it happened three times on the same day.
if fire did bring WTC 7 down and it was the first time in history of it happening, why wasn't one single building code changed as a result of it?

Sorry, i misspoke, it was the water lines to the building that were destroyed not the sprinklers themselves that failed.
Duh, no other 47 story building in history constructed the way this one was went with fires burning for several hours with part of its base knocked out...so yes, it was the first time in history this happened. But what does any of that prove on its own.
It's like you refuse to evaluate the evidence of why this was the first time in history that it happened. How can someone ever win an argument against your line of reasoning. That is why you adopt it rather than look to the actual evidence.
