The NIST Tries to ‘Repeal’ the Laws of Entropy and the First and Second Laws of Thermodynamics
by Len Hart
Under-estimating the intelligence of the American people, the NIST persists in papering over the endless holes in Bush’s official conspiracy theories of 911. Openly declaring that its new ‘report’ will finish off critics of Bush’s official conspiracy theory of 911, NIST has presumed to repeal laws of physics –the laws of entropy as well as the First & the Second Laws of Thermodynamics. Are we to expect Bush will now try repeal the equations of Galileo and Newton which describe precisely the free fall of sabotaged towers in New York? Perhaps Bush and his NEOCON co-conspirators will re-design the universe itself!
GAITHERSBURG, Md.—The fall of the 47-story World Trade Center building 7 (WTC 7) in New York City late in the afternoon of Sept. 11, 2001, was primarily due to fires, the Commerce Department’s National Institute of Standards and Technology (NIST) announced today following an extensive, three-year scientific and technical building and fire safety investigation. This was the first known instance of fire causing the total collapse of a tall building, the agency stated as it released for public comment its WTC investigation report and 13 recommendations for improving building and fire safety.”Our study found that the fires in WTC 7, which were uncontrolled but otherwise similar to fires experienced in other tall buildings, caused an extraordinary event,” said NIST WTC Lead Investigator Shyam Sunder. “Heating of floor beams and girders caused a critical support column to fail, initiating a fire-induced progressive collapse that brought the building down.” –NIST WTC 7 Investigation Finds Building Fires Caused Collapse
NIST states as fact a baseless assumption. NIST fails to address the temperatures required to melt steel and, thus, cause the collapse! The question then is not whether but when the building was prepped for demolition! NIST ignores the fact that WTC 7 had not been struck by airliners; the fires were secondary and comparatively cool.
According to the First Law of Thermodynamics, an increase in the internal energy of any ’system is equal to the amount of energy added by heating the system, minus the amount lost as a result of the work done by the system on its surroundings’.
The second law is a straightforward law of physics with the consequence that, in a closed system, you can’t finish any real physical process with as much useful energy as you had to start with — some is always wasted. This means that a perpetual motion machine is impossible. The second law was formulated after nineteenth century engineers noticed that heat cannot pass from a colder body to a warmer body by itself.
According to philosopher of science Thomas Kuhn, the second law was first put into words by two scientists, Rudolph Clausius and William Thomson (Lord Kelvin), using different examples, in 1850-51 (2). American quantum physicist Richard P. Feynman, however, says the French physicist Sadi Carnot discovered the second law 25 years earlier (3). That would have been before the first law, conservation of energy, was discovered! In any case, modern scientists completely agree about the above principles. The Second Law of Thermodynamics
The second law of thermodynamics is associated with increasing entropy, i.e, disorder. It states that in an isolated system, entropy will, over time, increase, reaching its maximum value at equilibrium. The fires inside the twin towers were never hot enough to have melted steel. The fires themselves cooled over time, never reaching or approaching temperatures required to melt steel. Something happened that should not have happeened. Entropy was interfered with! Something was added to the equation. Giving the game away and exposing the official lie is the fact that unnatural heat persisted long after the buildings had long collapsed.

Mind Boggling Conspiracy Theories
Reports of Controlled Demolition, Molten Steel, Thermite, etc.
I would like to know who is paying Richard Gage to go all around the country to spread his pseudoscientific deluge of misinformation typical of the absurd ideas put forward by the 9/11 ‘truth’ movement. Real scientists rarely speak of the truth until they have spent enough time and experimental effort examining the evidence. Its amazing to me how the ‘controlled demolition’ people most of whom have little or no knowledge or experience or expertise in the building collapse or fire protection area, just dismiss the reports of the top Fire Protection engineering experts in their fields and take some theological professor’s absurd babble about engineering as gospel. I suppose if your car didn’t start you would call the pizza man. The vaguest possibility is immediately touted as the truth and repeatedly echoed on the internet without any research or fact checking. Four years after the 9/11 attack and without inspecting any of the steel the Architect Richard Gage was listening to some equally uninformed Philosophy Professor, David Ray Griffin and had an epiphany and from then on he ‘knew’ that the buildings “had to be brought down by explosives”. “That’s the only way that you could have all the exterior columns in Building 7 fail within a fraction of a second.” How does he know all the columns failed at the same moment? These lower columns were out of sight of the cameras. The first thing to fail was the east side interior columns as evidenced by the east penthouse on the roof caving in. Five seconds later the west penthouse caved in indicating core column failure and than the exterior frame started to descend, but there were large belt trusses around the entire building between the 22nd to 24th floors. There could have been many exterior columns failing at different times below these belt trusses but these trusses held the upper building steady until a large number of lower exterior columns had failed. Building 7 took over 13 seconds to collapse not 6. NIST computer models show that the building was deconstructed by the heat of the uncontrolled fires buckling beams, disconnecting structural steel, and eventually buckling one key column which started the progressive collapse.
The top experts in the field. Shyam Sunder the NIST lead investigator, Gene Corley the American Society of Civil Engineers lead investigator both of whom have years and years if engineering experience. Gene Corley who was also the lead investigator in the Oklahoma City disaster, - which was destroyed by explosives, - said there was “no evidence of explosives” at the WTC site. He and Johanthan Barnett another experienced Fire Protection Engineer were on the scene immediately and examining the steel. Dr. Barnett described the devastation caused by the interior collapse of Building 5 from fire when the steel beams pulled out from their connections. These are all recognized experts in their fields and have to get things right in order to maintain their positions. I doubt a person inexperienced in the fire protection field could prove them wrong on anything related to the towers collapse without years of study, but they keep trying. The BBC put on the top building demolition expert Mark Loizeaux who explains how the towers collapse could not have been a controlled demolition and all he gets is blasted by the 9/11 ‘troofers’ for being ‘in-on’ the conspiracy.
Kevin Ryan knew nothing about how floor assemblies are tested by his own company Underwriters Laboratory. He reported that they tested the steel and it withstood 2000 deg for 3 and 4 hours. The UL tests floor and wall assemblies not the steel per se. The problem is that the long span floors used in the towers were never tested in their long span composite configuration of 60 feet. Building 7 also used long span steel “I” beams. As any architect knows the longer span floors require either massive joists or beams uneconomical for high rise buildings or specially designed construction such as steel trusses. What most architects apparently don’t know is that lightweight, long span steel trusses and “I” beams can fail at fire temperatures not yet compensated for in the codes. The standard furnace test can only handle 17 foot lengths of flooring and doesn’t test the connections for fire exposure. The furnace standards were set in the 1930s, 40s, and 50s when about 15 to 20 feet was the standard span used in high rises built for the more conservative codes used at that time. These older buildings used shorter spans, more robust columns and beams, stronger connections and better fireproofing then now. If a floor failed the push-out forces of expansion and the pull-in (catenary) forces created by the short spans were easily handled by the strength of the rest of the structure. For this reason the codes allowed floors to have a shorter (3 hour) rating than the columns and girders (4 hours). The 17 foot furnace test, currently still used, is meaningless for the longer spans and connections. The main problem in the WTC flooring was due to the differential elongation (expansion) of the steel parts of the trusses. NIST’s studies found that the different expansion rates immediately deformed the steel parts, buckled the top chords and struts and disconnected the composite bond between the concrete slab and the joists. Greater thermal expansion of the bottom chords releases the tension and allows the cool top chord to sag until it acts as a cable in suspension creating pull-in forces on the columns. Contraction of sagging, long span steel flooring during the cool down faze after fire die down puts heavy pull-in loads on the connections. It is known now that Building 7 collapsed from expansion and contraction in the beams disconnecting enough of the beams and girders to affect column stability. The whole interior and core failed before the perimeter wall which came down as a unit at 40% less than free fall speed.
Many people interpreted the loud sounds and debris being projected out sideways during the Tower collapses as an indication that explosives were used to demolish the buildings. Most of these loud sounds, heard during the collapses were heard after the collapses began. In order for an explosion to cause a collapse it would have to occur before the collapse. Some ‘thunder’ sounds were heard before the columns buckled and these were probably from floors collapsing. Explosive forces great enough to destroy the columns would be as loud as ten times the decibel level (140 db) of standing next to the speakers at a rock concert.
The undamaged exterior walls can be seen bending and buckling inward in the videos of both Towers long before any sounds or ground vibrations occurred. In Tower 2, the exterior columns in the east wall were photographed bowing inward up to 10 inches, 18 minutes after the plane’s impact. That’s 38 minutes before the global collapse began. To be technical, you could say that Tower 2’s collapse began slowly, with possibly some noise or impact sounds from falling floors, about 38 minutes earlier than the official collapse time. The explosive sounds and expanding dust clouds occurred just after the east wall buckled inward and started the collapse, and not before the buckling, as would have had to have happened with controlled demolition.
When the undamaged south wall of Tower 1 was photographed it was bowing inward up to 55 inches on floors 95 to 101, about six minutes before these columns were seen buckling inward. This bowing was witnessed and video taped by the Police Aviation Unit. In the North Tower “thunder” sounds were heard when some floors apparently collapsed on the south side 12 to 14 seconds before the top of the building was seen to tilt southward and begin falling as a unit starting the global collapse. Since each section of floor on the long-span side weighed about 500 tons, I would explore these ’supposed explosive’ sounds in Tower 1 as evidence of a floor or floors detaching and impacting the floors below on the south side which most probably accelerated south column wall failure. The boom, boom, boom, boom, boom repetitive sounds reported by firefighters running as Tower 2 was coming down were most likely caused by the sequential collision of impacting floors after the top of the building began falling. The great quantity of air on each floor being compressed in a fraction of a second by great weight and momentum would propel air, smoke, and any concrete dust and debris outward from the building at great velocity by the bellows effect of the floors coming together so quickly.
Initial Collapse Cause
Much has been made of the fact that NIST only analyzed the events up to the point where the Towers were poised to collapse before runaway collapse began and failed to pursue the remaining collapse. This was largely because after collapse began the chaotic impacts of the floors, Tower’s walls and columns colliding could not possibly be analyzed accurately with even the strongest computers. As it was, it was a severe strain on computer capabilities to analyze the mechanism of collapse up to the point of runaway disintegration. By dint of super computers running for extended periods of time NIST did examine almost the complete collapse sequence of building 7.
Bar joist Floors
It is clear from the computer studies that the heat from the fires caused differential expansion of the steel parts in the long span, floor trusses in the towers with the resulting thermal bowing in some floors directly exerting pull-in forces on the exterior columns or this thermal bowing could have detached a floor which would have impacted the floor below destroying its composite action by separating the concrete slab from the trusses and inducing strong tensile (suspension) forces in the double weighted floor. In other floors thermal expansion of the floor against the columns compressed the trusses which along with shear forces within the trusses that buckled the diagonal struts collapsing the trusses which went into suspension (catenary action) and this also helped pull-in and eventually buckle the exterior column walls. Differential thermal expansion of the concrete and steel has also been shown by NIST to disconnect the knuckles (knuckles are the steel tops of the bent over bars in the trusses which are imbedded in the concrete slab) from the concrete slab causing loss of composite behavior in the floors.
All these adverse floor truss effects were caused by steel expansion which begins immediately as the steel is heated. Bowing and buckling can happen at low temperatures (300 C to 500 C) even before the steel would have weakened excessively from higher temperatures. Thermal contraction caused by cooling of sagging trusses or ‘I’ beams after the fire ‘burns out’ or dies down can cause strong pull-in forces on the exterior columns and core columns due to the contraction of the sagging steel trusses or ‘I’ beams.
Columns
In order for a column to support the loads it has to be plumb and in line with the columns above and below. The fact is, columns have to be axially (in line and centered) aligned to support the weight of the building above. If they get out of alignment by 10 to 20 degrees they buckle and can no longer support the weight. The tower buildings collapsed because the floors first caved in from restrained thermal expansion and from thermal bowing or delamination of the slab and bar joists affecting floor truss stability. The sagging, 60 foot long, floor trusses gradually pulled-in the 59 columns in one exterior wall in each tower and these column walls eventually buckled removing support on one entire side. In Building 7 floor failures from steel expansion and/or contraction disconnecting the floor beams exposed a critical column to loss of lateral restraint over many floors causing the column to buckle and remove support for all the floors above and starting the complete collapse of the building.
In the Towers once the exterior columns buckling spread, along an entire wall removing support on one face, the buckling spread around the towers exterior and into the core and the towers began to tilt. With all the columns buckled the leaning top sections of the tower began to fall straight down. Although the North tower antenna appeared from some northern angles to have began falling straight down it actually tilted to the south because the south wall buckled first and the cantilevered top building section pulled the core along with the entire top over to the south. This is especially telling since with all the damage from the plane impact on the north side, the tower should have leaned over to the north. The South Towers’ top tilted to the east because its east wall buckled first. Once the tower’s tops began tilting all the columns across the buildings would eventually be out of alignment enough to have easily buckled.
The core columns depended on the floors for lateral support once they lost lateral support and got out of plumb, there would have been little resistance to their buckling at the weak splices. After the upper part of the buildings began descending, with the incredible weight of the top of the buildings’ gaining momentum, like a heavy wedge or sledge all it had to do was break the welded, and single bolt connections holding the floors to the columns. This is coupled with the fact that the falling top section’s momentum increases as the square of the number of floors impacted as the floors were detached and added to the weight of the descending top. There would have been little resistance to slow the top section’s increasing mass of impacted floors acceleration to the ground. Because this acceleration due to gravity increased the speed and momentum of the collapsing floors and building top, the impacts were increasingly violent as shown on the seismic graphs; increasing in amplitude until maximum when the mass of accumulated floors hit bedrock seven stories into the cellar.
There have been some engineering analyses about the impacting floors slowing down the collapse so that the time to collapse should have been much longer than ‘free fall’ times of an object dropped from the towers tops. Once the buildings started to tip over from loss of column support on one side, the tremendous excess eccentric weight began buckling all the columns across the building. Once the tilted building’s tops began descending the columns hit the floors or the lower columns at eccentric angles which easily detached the floors and buckled the columns. In order for the lower building section to offer any meaningful resistance to the falling building top, the columns would have had to hit each other exactly in line and plumb and this was impossible with the top of the building leaning causing eccentric angles of impact.
Once the top building section began tilting the columns on the side that originally buckled did not line up at all. These columns would have been hitting the floors and would have easily detached or buckled them. After the east wall buckled in Tower 2, the adjacent perimeter wall columns buckled from overloads and the columns on the opposite west side of the building, which were still attached and acted as a hinge would still be bearing on each other but at an eccentric angle which means they also would have also eventually buckled as the top tilted. These columns along with some of the core columns as they buckled are probably what kicked the bottom of the top building section to the west as reported by NIST. Because of the weight of the accumulating collapsing floors, there was a release of incredible potential energy changing to kinetic energy and building momentum as the accumulating chaotic mass of debris accelerated into the cellars.
Since the Tower’s outer wall columns, especially in Tower 1, pealed out like a banana after the building top began to impact the floors, these wall columns may have been able to break the connections to the floors ahead of the floors being impacted? In other words, with the weight of the wall columns pealing outward from the vertical along with the added horizontal forces of impacting floors projecting debris outwards onto these columns, these columns, while leaning out, might have been able to break the wall-to-floor connections ahead of the level of impacting floors? If this is possible than I believe that the connection failures could have traveled down the sides of the buildings at a speed faster than free fall times. This might explain the rapidity of the collapses especially in Tower 1. The wall-to-floor connection failures could have traveled down the building sides faster than ‘free fall’ times and in effect started the floors falling before they were impacted by the accumulating mass of impacted floors above.
The heavy exterior wall columns in the 1500 foot high buildings while pealing off could project the column sections outwards a great distance. This distance (300 to 400 feet) was proposed as only being made possible by explosive forces. I disagree. If a wall is strong enough and doesn’t break up as it falls outward it can fall out flat to a distance equal to its height. The Tower walls, however, did break at the weak splices as they fell. The fact that the exterior wall columns can be seen in the videos and pictures falling outward and downward and reaching the ground before the tower finished collapsing proves that the tower did not collapse faster than free fall times. These outer wall sections were falling at free fall speed and apparently were the first to hit the ground.
The compression of the 12 foot chunk of air on each floor down to a fraction of an inch in a fraction of a second as the floors came together would propel the air smoke and dust outward from the building at great velocity. The lightweight aluminum cladding as it broke free from the buckling columns also would have been propelled outward a great distance by this expanding cloud of air and dust. This air compression would account for huge dust clouds and pieces of aluminum seen projected outwards from the upper sections of the collapsing buildings. The light reflected off the aluminum pieces at the north wall of Tower 2 would be interpreted as flashes from explosive ’squibs’. The flashes below the buckling east wall may have been from the aluminum cladding breaking free from the lower columns as they expanded after being unloaded of axial compressive weight by the buckling of the wall above and their expansion breaking the connections to the cladding. Also explosives leave characteristic tears and fractures in steel and especially in aluminum, and such indications were not found anywhere in the debris pile.
The compression of air in the elevator and air-conditioning shafts by the collapsing upper building section and floors, would project air, smoke, and dust down these shafts and out any path of least resistance or any of the HVAC air intake or discharge openings on the lower mechanical equipment floors in the exterior walls. This accounts for the plumes of smoke seen projecting outwards sideways from the buildings well below the collapsing floors. There were quite extensive Heating, Ventilating, and Air Conditioning (HVAC) shafts built into the building. These vertical shafts are connected to air conditioning exhaust and intake ducts open to the exterior on the mechanical floors.
Deep Seated Pockets of Fire
After any fire in which a building collapses, there often remain deep seated, pockets of fire deep within the rubble pile These pockets of fire sometimes cannot be reached by water streams because of their being covered by debris. Air is sometimes drawn up from the bottom of the pile and feeds these inaccessible fires with air. These fires can last for days and the heat can become intense and can heat any steel in proximity to the fire until the steel is glowing red, orange or yellow hot. These pockets of fire are common at burning building collapses and in no way evidence that that explosives or thermite were used to demolish the buildings. These fires are similar to blacksmith forge fires where air is blown into the charcoals by a bellows to raise the temperature of the fire to heat a piece of steel or iron. The blacksmith can tell how hot the steel or iron is by its color and can tell when the steel is soft enough to work it with a hammer The deep seated fires which occur in the rubble are supplied with air because natural convection currents. Heated air rises because of its bouyancy and is replaced by cool air drawn in from the bottom and sides of the fire. This air flow can become rapid because of the high temperatures developed. The more air drawn in the hotter the fire becomes and the increased temperature increases the convection currents which draws in more air. Like in a furnace the containment of heat by insulation provided by the compacted combustible material surrounding the fire allowes the gradual increase of temperature. I am convinced that temperatures of over 2000 deg F. can easily be developed in these deep seated pockets of fire in the rubble of a collapsed building.
These inaccessible fires often have to be dug out by hand tools, back hoes or grapplers in order to expose the burning material for extinguishment. It is common to hold off hitting the fire with water until it is fully exposed in order to prevent the great amount of steam that would be created from obscuring the work area until the fire is fully exposed and can be quickly extinguished. This is what is happening in the picture of a grappler pulling out a piece of glowing hot steel from the debris pile so often described as molten steel. Such ordinary fires are incapable of melting steel unless they are supplied with enough oxygen.
Much has been made of the presence of molten metal in the debris pile after the collapse. Presumably this molten metal was somehow thought to be connected to explosions or thermite charges, but there were Uninterrupted Power Supply (UPS) battery rooms on some floors of the Towers and Building 7. These battery rooms supplied continuous battery power to computers if the electricity failed for any reason. These batteries contained tons of lead which melts at low temperatures [327 C (621 F)]. The heat from the fires in the debris pile could easily have melted this lead or the aluminum from the plane or aluminum from the tower’s own cladding which were probably the metals that were seen flowing through the pile. NIST reported UPS in the 13th floor of Building 7 and the 81st floor of Tower 2. There were also quantities of lead, tin, silver and even gold used in the computer circuit boards. In the some people’s minds molten metal becomes rivers of molten steel.
Additionally the EPA reported over 400 different chemicals in the dust and debris. These chemicals could easily be assembled conceptually to propose any type of chemical reaction imaginable including thermite reactions. In addition thermite reactions are rapid and wouldn’t last the hours or days at which times the molten metal was observed. As far as I know thermite has never been used to demolish buildings and the expertise probably doesn’t exist. Thermite is hard to control and can’t be held against the columns because it would burn down through any material used to support it against the columns.
Pure oxygen is used in oxyacetylene torches to actually ignite burn and melt the steel when cutting. These torches were used to help clear the debris pile during search and recovery operations. A slag of melted and re-solidified steel and Ferrous oxide is formed on the opposite side of the cut. This slag formation and the angle of the cuts were erroneously reported to be evidence of cutter charges having been used to sever the columns. Small molten pieces of glowing steel cool into spheres as they fly out from the cut. These steel microspheres could also have been produced during the buildings’ construction by welders and retained in the concrete or else where only to be released during the collapse.
About the concrete destruction into dust; F.R. Greening did a paper called Energy Transfer in the WTC Collapse in which he says “the energy required to crush concrete to 100 ?m particles is 1.9 × 1011 J, which is well within the crushing capacity of the available energy. Hence it is theoretically possible for the WTC collapse events to have crushed more than 90 % of the floor concrete to particles well within the observed particle size range.” http://nistreview.org/WTC-REPORT-GREENING.pdf I would also investigate the possibility that the concrete was sub par due to freezing during curing or too much air or water having been added during the pouring and finishing operation.
Do you think the architect or engineers who built the Towers would want to admit the deficiencies in design, fireproofing and other construction weaknesses after their buildings collapsed? Do you think they will get any other jobs after 4 of their buildings collapsed from fire? (Building 5 had a serious interior multiple floor collapse due to fire.) Do you know that the Port Authority of NY, NJ didn’t legally have to follow any building codes? The reason the columns broke at the splices was that they had serious weaknesses due to lack of reinforcing plates or even welds on most of the exterior column, bolted splices and not because they were broken up into short pieces, presumably by explosives, ‘so they would fit onto the trucks to be carried away’. The long span truss floors were never tested for fire resistance at their design length. Why do you think it took so long to get the plans for the buildings after they collapsed while the building engineers had them all along? I would think the architects and engineers for 9/11 truth would be more accepting of any excuse that would allow them to avoid the introspection necessary to fully realize their own lack of knowledge of fire safety precautions, even the wild idea that explosives or thermite was involved.
About the eye witnesses; there are many reasons that loud sounds can be produced at a fire. Most of the people in tower 2 did not know tower 1 had been struck by a plane but they heard the explosion and even felt the radiant heat produced by the fireball. Often at fires the ones closest to the fires and engaged in heavy work or evacuation have a very limited overall conception of what is actually happening. When you don’t know what’s happening your imagination starts to work. When tower 2 collapsed most of the people in Tower 1 thought the sounds and vibrations came from the building they were in and they even felt a rush of air up the stairs as the air was compressed in the cellars. There can also be smoke explosions (backdrafts) particularly in fires that have a flammable liquid involved. One elevator shaft that extended into the cellars had a fuel-air explosion from the jet fuel spilling down and evaporating in the shaft. There were other fuel-air explosions in the elevator shafts. There could have been floor detachments impacting the floors below and producing loud sounds before any general collapse began. Explosives also produce loud distinctive pressure waves that can leave people deaf or blow out eardrums and usually blow out all the windows on the particular floor and in any buildings nearby. This kind of sharp piercing crack was not heard. The windows broken out and marble wall panels detached on the interior of the first floor lobby were probably because of torque or bending forces experienced on the lower floor columns from the plane impacts many floors above. The buildings were reported to sway several feet when the planes hit the towers. The reports of “explosions” in the cellars were also probably from such column or floor displacements or from jet fuel ignitions in the elevator shafts. If you imbed a stick into the ground and hit it with another stick most of the deformation will be in the ground around the bottom of the stick. There were reports of split walls and ceiling collapses on many floors after the planes hit.
How do you think that the supposed Conspirators knew that Building 7 would be hit by pieces of Tower 1 which would set it on fire? They would have to know this beforehand in order to set the mysterious explosive charges. Why did they wait 5 hours while the fires burned to set off these alleged charges, and how did these so called charges withstand the fires for 5 hours without igniting? The computer models show steel beam, thermal expansion, sagging and disconnection from the columns due thermal expansion or contraction of the beams due to the fires.
How come the, A&E, 9/11 ‘truthers’ never mention Building 5. Did building 5 which had a serious fire on many floors and had several floors collapse from the steel beams being disconnected from the columns due to thermal expansion sagging and catinary action tearing out the bolted beam connections. (ASCE, Building Performance Study) I propose that some of the ‘truthers’ never even read the American Society of Civil Engineer’s or the NIST’s report. Did building 5 also have charges set beforehand? How many other buildings had hypothetical charges set beforehand and were never set off? If they went to all the trouble to rig all these buildings with assumed explosives, why didn’t they just set them off and forget the planes and the fires. Waiting for the planes and fires would surely increase their chances of being detected
There are so many questions answered by the fire theories and so many unanswerable questions posed by the demolition theories that it is ludicrous to continue the proposition that explosives had to be employed to collapse these buildings.
BBC reporting error on Building 7 collapse.
In addition to the damage done to Building 7 by the heavy steel column trees that pealed off of the collapsing twin towers some of these steel columns penetrated the roads and broke the nearby water mains. There was no water supply immediately available and the Fire Department Chief in Command could not fight the numerous fires in Building 7 and ordered every one out of the building and out of the collapse zone (which was a large area including buildings and streets around Building 7). Two huge buildings had already collapsed and when you can’t fight a fire because there is no water pressure it grows out of control apparently now all bets are off as to exactly what will happen in one of these newer lightweight, open area high rise office buildings.
When anticipating possible collapse it is the procedure to discontinue interior operations and clear the building and establish a collapse zone around the building. The anticipation of collapse was a brilliant call and no lives were lost when the 47 story building collapsed a few hours after the evacuation order was given.*
You ask “How did the BBC know that the Towers were going to collapse?” The BBC didn’t know. Did you ever hear a mistake made by a reporter? Or do you believe everything you are told by a TV reporter in the heat of an emergency? The BBC reporter on the air received an erroneous report that the tower had collapsed before it actually did and reported it well before the actual occurrence. It was a simple mistake.
I can imagine how it happened. Possibly a reporter on being told to evacuate the area by a rescue worker balked and to get him to move faster the worker told him the building is coming down. The reporter called his boss and told him the building 7 is coming down. The person receiving the call believed the building was already collapsing. It went out over the air as the building had already collapsed before the actual occurrence.
Of course if you believe that all the top fire protection engineers from the American Society of Civil Engineers (ASCE) and government scientists from National Institute of Standards and Technology (NIST) investigating the collapse are in on a conspiracy and also want to accuse the BBC, the NYC Fire Department, the NYC Police Department, the Red Cross and all the Government agencies controlling access Building 7 of being ‘in on’ a secret controlled demolition even though there was no hard evidence than I would say you are suffering from a case of paranoia. Paranoia can easily become contagious when people panic and no longer trust their government. We certainly have reason not to trust our present government. I would say that if you really believe these ridiculous conspiracy theories you should do some soul searching and possibly seek some therapeutic help.
* This is a message from Chief of Department (ret.) Daniel Nigro, addressing the conspiracy theories surrounding the collapse of WTC7. Thank you very much for this statement, Mr. Nigro. The work you and your colleagues did will never be forgotten.
Release date: September 23, 2007
Regarding WTC 7: The long-awaited US Government NIST (National Institute of Standards and Technology) report on the collapse of WTC 7 is due to be published at the end of this year (although it has been delayed already a few times [ adding fuel to the conspiracy theorists fires!]). That report should explain the cause and mechanics of the collapse in great detail. Early on the afternoon of September 11th 2001, following the collapse of WTC 1 & 2, I feared a collapse of WTC 7 (as did many on my staff).
The reasons are as follows:
1 - Although prior to that day high-rise structures had never collapsed, The collapse of WTC 1 & 2 showed that certain high-rise structures subjected to damage from impact and from fire will collapse.
2. The collapse of WTC 1 damaged portions of the lower floors of WTC 7.
3. WTC 7, we knew, was built on a small number of large columns providing an open Atrium on the lower levels.
4. Numerous fires on many floors of WTC 7 burned without sufficient water supply to attack them.
For these reasons I made the decision (without consulting the owner, the mayor or anyone else - as ranking fire officer, that decision was my responsibility) to clear a collapse zone surrounding the building and to stop all activity within that zone. Approximately three hours after that order was given, WTC 7 collapsed.
Conspiracy theories abound and I believe firmly that all of them are without merit.
Regards, Dan Nigro
Chief of Department FDNY (retired)
In conclusion I think all the reports of controlled demolition can be explained by sounds or sights produced by the plane impacts and jet fuel and air explosions; the sounds of the Towers collapse. When the interior of building 7 collapsed it would have produced loud sounds before the exterior walls began collapsing.
