i mean when you look at it the building has collapsed that tower just came down trade center building number seven on september eleventh two thousand and one it was one of the casualties of the terrorist attacks building seven sudden and shocking collapse has been overshadowed by the fate of the twin towers but from an engineering standpoint it is no greater mystery we were surprised that tower seven collapsed  being the team that investigated what occurred on that day there was some damage to tower seven caused by the debris that hit from tower one but the damage was certainly not similar in scope or magnitude to that caused by the aircraft hitting towers one into the only positive aspect of this building's demise is that it fell seven hours after the two main towers everyone had been evacuated and even though the forty seven story building collapsed in on itself in under ten seconds no one was killed whatever seven was completed in one nine hundred eighty seven it had approximately one point eight million square feet forty seven stories and was roughly six hundred feet tall it's in the floors was approximately forty thousand square feet which is roughly the size of a football field and equal to the size of the floor plate on each of the towers the building was a good building it was soundly you believe in a conspiracy in terms of the attack of nine eleven no but i do believe that it is the first time in history that fire has ever melted steel i do believe that it defies physics for the world trade center tower seven building seven which collapsed in on itself and is impossible for a building to fall the way it fell about explosives being involved world trade center seven world trade and one and two got hit by planes seven miraculously the first time in history steel was melted by fire it is a physically impossible and who do you think is responsible for that i have no idea but imagine if somebody could convince you of that they could prove it to you elizabeth just seven did you know that a third tower fell on nine eleven at approximately five twenty p m on september eleventh two thousand and one world trade center building seven collapsed in six point five seconds from normal office fires according to the government's final report one trade center seven collapsed because the fires fueled by office furnish it did not collapse from explosives oil fires later the government finally admitted that building seven collapsed at the rate of freefall after trying to deny it so what's wrong with a building in freefall what is freefall just like taking  out just dropping that's how fast the building can go for over one hundred feet this is high school physics a building cannot do freefall with forty thousand tons of structural steel and its structural system without it being blown up the only way that a building can accelerate as it collapses is by having pre engineered precisely timed and precisely placed explosives in other words controlled demolition saw the big hubbub going on around the building seven walked around it saw a hole and see hole bad enough to knock a building down now so you know yeah there was definitely fire in the building you know but i didn't hear any you know what a maze maybe this is a movie crap i didn't hear any creaking or i didn't hear any any indication that it was going to come down and all of a sudden the radios exploded and everybody started screaming get away get away get away from it and i was like a deer in headlights and i look up and i think i think i remember pretty clearly the two guys  knew were on the transit radio i don't know if those tapes are out there but i can i can try and reform and show you exactly what i'm talking about but it was that moment you know going away and i looked up and it was nothing i would ever imagine seeing in my life and all the things started peeling in on itself and i mean there was an umbrella of crap seven feet over my head that i just stared at so we're like ok you know we'll take their word for it you know we'll stay behind the line and he went over and he talked to one of them for all the commotion he goes over to ask one of the red cross one of the firefighters what was going on i guess i don't know if you got an answer or not he came back over with his hand over the radio and what sounded like a countdown and that the last few seconds he took his hand off you heard three to one and he was a single trying to feel life just run for your life floors that were dropping collapsing this was like you felt a rumble in the ground like almost like you want to grab on to something that to me i knew that was it explosion there was no doubt in my mind just in the last few seconds another building building number seven one of the buildings in support of the world trade center towers has collapse this is no small building if you can see it forty seven stories it would stand out in most american cities remember getting a call from the fire department commander telling me that they were not sure they're going to be able to contain for a high rise building that was steel frame completely collapsed there have been fires burned longer in similar structures without any collapse in this test done by british steel in  five a large amount of typical office furniture was burned to see what would happen to the heavy steel beams that supported the ceiling it's not that it melts in a fire in fact the fires of normal fires are not hot enough to melt even if you were for example to use an unusual fuel like kerosene you cannot achieve temperatures hot enough to melt steel but what happens is it starts to lose its strength and as it loses its strength it starts to sag this was the largest test of its kind ever conducted it showed how unprotected steel can be distorted even by a normal office fire but as is typical in st buildings the structural beams only slowly and progressively warped and sag there was no chance of a sudden collapse in my previous career as a firefighter normally you'd never be afraid to go into a type one building because they're not combustible and you would just charge at it and put the fire out and never in my training were we ever taught that these type of buildings could just collaps there's definitely much more going on just for the world trade center seven building reminds me of the meridian bank building and in some ways in philadelphia the meridian bank building is a thirty eight story skyscraper that burned for eighteen hours hundred ninety one suffered extensive damage from the fire but did not collapse the nest tells us that this collapse mechanism starting with thermal expansion that worked its way up toward an outward through the building in a matter of seconds there's not enough time for the building to collapse the way that nest tells us a collapsed this claims the fires were very large very hot and long lasting when in reality observation which has been researched by many people shows these fires that were the last very long they were not in the locations were missed claims they were given times and i'm a fellow of the american institute of architects for the forty plus years that i've been practicing architecture i've designed a variety of buildings from small houses to high rise office buildings some of the high rises that i've worked on are one shell into shell here in houston i was project manager for a twenty two story office building in akron ohio later in the day when were trade center seven collapsed they had already showed us pictures of a few fires in that building and i mean they weren't even raging and how could that cause a building to collapse as if it were imploded but that's exactly what investigators believe happened to the forty seven story world trade center building seven on september eleventh according to a three year comprehensive building and fire safety investigation just completed by the national institute of standards and technology or nist well trade center seven collapsed because of fires we really have a new kind of progressive collapse that we have discovered here which is a fire and use progressive collapse and fact we have shown for the first time the fire can induce ever aggressive collapse nist use detailed data describing the building and its contents to create the most complex computer simulation of a structure collapse ever made falling debris from tower one started fires on ten floors in building seven a break in the city water main from the collapse of the towers disabled sprinklers in the lower half of w t c seven allowing fires on those floors to burn for seven hours nist computer model was validated with evidence from videos photos witness accounts and other data it shows that heat from fires expanded long support beams causing connections and floors to fail so you look  her and eventually those columns seventy nine is going to buckle and fails and then the antara vertical progression takes place if the buildings had come down by far we would have seen a more natural progression of collapse and clearly more a symmetrical pattern should have been present the buckled column caused additional collapsed floors and falling debris that remove support from adjacent interior columns a chain reaction then caused other interior columns to fail in quick succession the outside shell of the building fell i worked for a controlled demolition of corporate at c d i the top rated explosive demolition firm in the world as an explosion floater my job was to place explosives in the buildings to prepare them for demolition i was licensed while in new york by the new york fire department to handle explosives and i worked on major projects such as seattle kingdome the free river stadium philadelphia naval hospital and the and key span gas holders in new york what i saw it was a classic implosion the center of the core the penthouse area starts to move first and then the building falls along with it that's another indicator that this this report is very suspect finished the outside walls are power went on top of the other right in the middle of the building just like a house of cards if it were coming down as a structural engineer i don't believe that the failure of one color would normally bring down an entire building in the way we saw world trade center seven come down according to nasa the failure occurred at column seventy nine on level twelve this means basically they're talking about a single column near collapse or failure that resulted in a total collapse of the building that just does not make any sense the nist team found no evidence that explosives were involved in the collapse and our analysis showed that even the away that would have been an incredibly loud sound and that sound was not picked up by any of the videos or witnesses that we have talked to in its final report of the destruction of world trade center building seven missed the national institute of standards and technology went out of its way to avoid investigating the use of explosives or sole rationale for not investigating explosive use was the supposedly lack of sufficiently loud sounds computed what they claimed would be the minimum loudness of an explosion that could sever column seventy nine with a single blast then they claim no observers detected explosions as loud as their predictions this size blast would have produced an incredibly loud sound that was not recorded on videos of the collapse nor reported by witnesses on the basis of this artificial threshold of interest they swept aside all evidence of actual explosions and concluded that no explosives contributed to the destruction of the building we did not find any evidence that explosives were used in the collapse of building seven explosion that's about the fourth one we've heard a few blocks up west broadway looking toward the world trade center in the distance ashley banfield was conducting an interview for m s n b c you were just told by police that you should move out of your mike was set to pick up speech a few inches away from the involuntary startle response oh my god we know explosions are being heard however listening closely we discover that the microphone did indeed pick up the sounds of all my god this time the sound has been filtered to emphasize low frequencies listen for booms like a bass drum in the dis here's a different version filter to emphasize the mid range sounds the bass drum is gone i would describe the blast sound like a train on a bumpy track you were just told by police that you should move out of your apartment turn up the volume and listen again there were two blouse followed by seven more regularly spaced all in two and a half seconds create partners testimony may come to mind the whole time here though i think i know an explosion i hear when we hear the sharp regular series of sounds in the background the building has not yet started to fall when we hear the reporter say this is it this is that the building has not yet started to fall the fall of the building corresponds to the crescendo in the crowd response here is another street scene with the building in full view the crowd responds almost immediately as the building starts to fall this occurs just after the reporter s before the blasts we heard it occurred seconds before the building started to fall when ashley banfield says this is it it is because she has been previously told to expect building seven to come down brown building the tall one is number seven world trade center there are several reports from several different offices now that that is the building that is going to go down next back in the studio to anchor brian williams not only had for knowledge of the collapse he had a ready explanation of what we've been hearing all afternoon as apparently happened we were watching a number seven world trade which was part of the ancillary damage of the explosion and collapse of the other two just as ashley banfield was told brian williams was told there is indeed evidence that even the top fire officials were told we are on the phone with the new york fire department lieutenant david rescue cio lieutenant where are you right now we are getting information now that one of the other buildings building seven in the world trade center complex is on fire and as you know collapse or is collapsing and clearly those fires continue to burn at about four fifteen eastern daylight building number seven was going to collapse that appears to be what has happened now one of the smaller buildings just huge the ground we heard earlier that it was structurally unsafe getting word from new york right now that another building has collapsed i understand that this is a forty seven story building information of course take a look at the right hand side of the screen it's going down right now there it is right down right there this is not there from an explosion or an aircraft at this point from our knowledge of the information we have is that this is a building probably was incredibly structurally damaged this does being dishonest that could have been an incredibly loud sound and that sound was not picked up by any of the videos or witnesses that we have talked to nist was lying about no testimony of explosions there was both testimony and recorded evidence of explosions however nist discounted any evidence of explosions that did not exceed its artificially contrived threshold of interest the minimum sound level of interest as determined by ness was based on a blast of r d x one of the loudest explosives available large enough to break a major column outright with a single blast is assumed no efforts at noise abatement complete transmission of the sound to the outside air no absorption or blockage of the sound along the path and who knows if they assumed the use of an efficient cutter charge or if they simply figured the effect of a bomb planted beside a column they don't say their sole reason for doing this calculation was to create a pretext to sidestep any actual investigation of explosives why would nist or anyone else choose to exclude from its investigation any evidence of any explosions related to the destruction of the building at the same time it should be noted that nist report on building seven was never published by a peer reviewed publication this means their analysis of the collapse cannot be validated from a scientific point of view even though this was an unprecedented event in history it's been analyzed and we have the results and we are very comfortable with our findings they might have been comfortable but the scientific community of architects and engineers was not science is never se unless it's published once it's all published and made available for criticism architects and engineers has asked nist to at least verify the computer model on which they've based their theory of the collapse but also in this case nist has refused to make their data public structural engineers rail against nist because they refuse to show the visualization it's a black box you cannot download any of this data this means that also for the accuracy of their computer model we have to take mists word for it here in our structural model showing the building collapsing which matches quite well with the video of the event this is the video of the event on the right is one of the two animations released by nist on the collapse of building seven when you observe the footage of the building failed and when you look at the the animation of the failure and compare that to what you actually observe in reality but i think they disprove their own theories it is impossible for it to feel the way they said the second animation released by nist is even more inconsistent with the real event while the animation shows a pronounced inward bending of the top of the structure the video footage shows the entire top section of the building maintaining its shape all the way through the visible part of the collapse this can be verified by different angles if this is what nist calls matching quite well one can imagine what the reliability of their entire report can be in order to justify the first ten only collapse in the history of the steel skyscraper due to fire the debunkers had maintained that building seven was weaker than the average steel structure because it had been built over an existing electrical substation the building was extremely unconventional it had this giant con ed substation with enormous trusses carrying extraordinarily high loads very vulnerable to fire and other kinds of damage but news to itself has refuted this possibility from the final report we read the transfer of elements cantilever overhangs that were used to support the office building over the con edison substation did not play a significant role in the collapse of world trade center seven in fact it was the opposite after it was completed is silverstein had the building reinforced beyond its requirements in order to accommodate the needs of its main tenant solomon brothers from this one thousand nine hundred nine new york times article we read solomon brothers intends to spend nearly two years and more than hundred million dollars cutting out floors adding elevators reinforcing steel girders upgrading power supplies and making other improvements in its million square feet of space we built enough redundancy to allow entire portions of floors to be removed without affecting the building structural integrity said larry silverstein president of the company more than three hundred seventy five tons of steel requiring twelve miles of welding will be installed to reinforce floors for solomon's extra equipment if there was one skyscraper in the world that should have never collapsed due to fire it was building seven in other news this week the finding that allowed the national institute of standards and technology to withhold  from its world trade center seven collapse simulation has finally been released by a whistle blowing site cryptome dot org the finding was made on july ninth two thousand and nine and reads in part quote the disclosure of the information in connection with  investigation of the technical causes of the collapse of the world trade center towers and world trade center building seven on september eleventh two thousand and one might jeopardize public safety therefore nist shall not release the information and quote of the finding was made last year the actual finding itself was not available to those who had requested the information leading many to suspect that it would contain details of exactly how or why the data from this w t c seven collapse simulation would jeopardize public safety but no such explanation is to be found analysts note the finding is especially odd given that in this that self has claimed that the collapse of the w t c seven was an extraordinary event unprecedented in history and that they arrived at that conclusion using the computer model whose input and result that are they have no classified in the name of public safety what we found was an uncontrolled building fires similar to those we have seen in other tall buildings caused an extraordinary event the collapse of world trade center seven was primarily due to fires this is the first that we are aware of that a building over seven to fifteen stories tall has called lapsed primarily due to fire questionable nature of the science underlying a simulation that many of pointed out is little more than a visual recreation of the initiation of a building collapse which in itself explains nothing and does not even show the entire progressive collapse of the forty seven story building jennings fifty two years old i've worked for thirty three years in one location when the office of emergency management didn't activation they always they always included it what it what we did was what they did was monitor the emergency they actually coordinated the emergency in several agencies i received the call shortly after the first plane hit i got to hear i had to be blew us back i'm thinking i'm not standing on a own on the landing i'm actually holding on to a pole above us and i had to climb back up because hess is yelling what do we do now i said there's only one thing we can do is and it's go back up both buildings were still standing both buildings were still standing both buildings were still standing keep in mind i told you the fire department came and rig they came twice why because the building how one fell then tower two fell and then when they all this time and hearing explosions when they finally got to us and it took us down to what what they call the lobby because i actually went and we got down the ice and well we he said this was the l not look down and i kept saying why did not look down and stepping over people and you know you could feel when you stepping over people this big giant police officer came to me and he says you have to run i said i can't run my knees a small he said you have to get on your needs and crawl and he said because we have reports of more explosions and that's when i started calling and i saw this guy fall behind me and his comrades came to his aid and dragged him to safety i'm just confused about one thing i want thing only why world trade center seven went down in the first place i'm very confused about that i know what i heard i heard explosions they did explode explanation i got was it was the fuel tank i'm an old boiler guy it was a fuel tank it would have been one side of the building yes you can use this one only when you have a structural  failure you carefully go through the debris field looking at each item photographing every being as it collapsed and every column where it is on the ground and you pick them up very carefully and you look at each element we were unable to do that in the case of tower two years ago but the folks behind that t v ad you saw earlier are not so easy to dismiss as those demonstrators were and what caught my eye is their claim that more than thirteen hundred architects and engineers examined the evidence about building seven collapsed and disagree with the official report issued by the national institute of standards and technology but outfront tonight building seven was no ordinary build among other key tenants including several intelligence and law enforcement agencies it also housed new york city's emergency operations center known as mayor giuliani's bunker here to tell us what they know about its collapse and why they question the official conclusions are bob official account that building seven collapsed because of the fire or melting the steel or in some other ways you know destroying the integrity of the structural integrity of the build that that's false you think that that's  and and for a couple reasons one is that building seven came down it went into a sudden collapse across the floor with them left the building for two point two five seconds which amounted to one hundred five feet or eight stories a thirteen admitted to that kate let me ask this for you get the dead forget the body we've all seen old obsolete buildings in public housing in other places outlived their usefulness being demolished by the professionals who can actually collapse of building right in it's own footprint that's what it looks like happened to building seven do you believe that's what happened so what's what and why do you think they're lying about it i don't really know all the details of water one of i can't read their minds all i can say is scientifically it does not it's impossible for far what we see and these and these bob these thirteen hundred engineers and architects who agree with you and some of the other relatives families i know you found your son just a couple of days after the disaster he was outside i don't want to get into the details of how you believe he died but these architects and engineers do they support your contention do you believe that it was an inside job that nine eleven was an inside job or in iran and i really i believe it was an inside job ok i'm here to believe our government put it but the thing is this we don't have enough time to get into about building seven and when the lawyers and you're asking the new york city council i don't know what up also i know he would have the time but anyway he said building what because he had no one has any idea about building seven so because i believe in so i've talked to so many firemen so many e m s workers policemen who talk about the explosions and i know you want to get in the white center but i feel my son died from an explosion i went to all the nine eleven commission hearings i have you know i've want the investigation in well the more of what we wanted is in new york city right now because new york city we feel has an obligation to investigate nine eleven before we're going to talk completely bob do you want specifically the new york city council to open it own investigation of the building seven collapse a little and that would satisfy you if they did that well done i'm still a parent i'm a parent who has an obligation to find out why my son was murdered  we thank you tony somebody thank you very much it is a intriguing topic i certainly am much more open minded about it than i was and it is because of the involvement of the nine eleven families and all these engineers and architects clearly they know more come from the on of questions of nine eleven really think night hi my name's eric lawyer i'm the founder of firefighters for nine eleven truth and more recently an organization called one becoming one i have over twenty four years in emerge service experience with the last sixteen in the seattle fire department and recently retired you don't injury and i'm now pursuing my passion of helping bring more love and compassion in the world it's going to take courage and compassion to transform our world from one of fear to one of love because i'll be honest it is scary to talk about nine eleven it's scary to consider that you know that it's something other than what we were told but by having that courage it's like facing two abusive parents and facing them with love and compassion by moving through this we all begin to heal and by and shining the light on it we can actually make some radical transformations and make that shift from fear to love did you know critical nationals and it's for fire investigations were ignored on all the nine eleven investigations did you know almost all of tower seven's physical evidence was destroyed before any investigation began ben franklin said it is the first responsibility of every citizen to question authority these questions and many more are needed dressing because our world is being shaped by what we were told happened on nine eleven our current solutions involve violence secrecy corporate and government intrusions einstein said we cannot solve our problems with the same level of thinking that created them meaning to me that fear based problems cannot be solved with more fear by having the courage to compassionately rethink nine eleven we create opportunities for new and positive solutions i also appreciate rethink nine eleven is a global and grassroots action campaign coming together in a spirit of brotherhood responsibility and remembering that we're all in this together this is a crucial step in transforming our world from one of fear to one of love thank you for reconsidering nine eleven
