So speaking of what actually brought down the building - fires, you must know they burned for several hours as the sprinkler lines were knocked out...and that caused the weakening of the columns... I know from some vantage points you can conclude it was isolated small fires, but just watch this video and also what the firefighters say about pulling back as it may fall... http://www.911myths.com/WTC7_Smoke.avi |
again i ask, how can fire cause a steel building to collapse? even buildings completely engulfed in fire for several days do not collapse.
sprinkler systems are run in parrallel, not series so knocking out one section won't disable the safety feature for the entire building!
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?
