Part 2. Modern history - Nuclear demolition of skyscrapers

So, how come that this old atomic demolition concept, despite of being known to be too costly and despite of having a too low performance index compare to a conventional controlled demolition by implosion was eventually revived and even implemented in the World Trade Center nuclear demolition scheme?

It happens because of a new generation of buildings has come into existence at the end of 60s - namely steel-framed buildings. Despite common misconception, there were no steel-framed skyscrapers ever been demolished by an implosion anywhere in the world.

Primarily, because the most of skyscrapers are new buildings and their time to be demolished has not come yet. The tallest building ever demolished by an implosion was only 47-strories high - it was the Singer Building in New York City that was built in 1908 and demolished in 1968 due to its being obsolete. This building was a much weaker structure compare to incredibly strong hollow-tube type steel-frame skyscrapers being built today.

So, despite common misconception, it is not possible to demolish a steel-frame building by a commonly known controlled demolition (implosion) scheme. In bygone days when buildings were brick-walled and concrete-paneled, their bearing structures used to be concrete supporting columns and concrete supporting girders.

Sometimes these concrete bearing structures were reinforced by insertions of metal bars, but sometimes they were plain concrete. In either case it was possible to calculate right amount of conventional explosives to be attached to these bearing structures at right spots (or to be placed into holes drilled in bearing structures) in order to break them all at once and to cause the building to collapse into its footprint.

However, it is no longer possible with modern steel-framed buildings - such as, for example former Twin Towers of the New Your World Trade Center, World Trade Center building # 7, or the Sears Tower in Chicago.

Here is an example of steel structure of the WTC Twin Tower:

WTC Twin Tower under construction.
 

There was no any "bearing structure" in its former sense - the entire Tower was essentially a "bearing structure".

The WTC steel-frame consisted of exceptionally thick double-walled steel perimeter and core columns. This co-called "tube-frame design" was a totally new approach which allowed open floor plans rather than columns distributed throughout the interior to support building loads as it was traditionally implemented in previous structures.

The Twin Towers featured load-bearing perimeter steel columns (square in cross-section) positioned one meter from each other on the Towers' facades to form an exceptionally rigid structure, supporting virtually all lateral loads (such as wind loads) and sharing the gravity load with the core columns. The perimeter structure contained 59 such columns per side.

The core structure of the Tower consisted of 47 rectangular steel columns that run from the bedrock to the Towers' tops.

How such steel perimeter and core columns looked like could be seen from this picture showing some remnants of these columns as found on the ground zero after the WTC demolition following the September 11 attacks:

WTC core and perimeter columns.
 

Note that these core (rectangular) and perimeter (square) columns did not belong to lower parts of the Twin Towers, but to their upper parts.

That is why they were spared by general pulverization the Towers were subjected to during their demolitions, while virtually nothing, except microscopic dust remained of similar columns belonging to the lower parts of the Twin Tower structure.

Here is one more picture (from NIST report) showing the Twin Towers perimeter columns during their construction:

Twin Towers perimeter structures.
 

These steel columns were incredibly thick - each wall measuring 2.5 inch (6.35 cm), so the entire thickness of either of the columns was 5 inch (12.7 cm).

To imagine how thick this is, here is a good example to compare with: front armor of the best tank of the WWII period - T-34 - was only 1.8 inch (4.5 cm) and it was single-walled. Yet there were practically no armor-piercing artillery shell available that time that would be capable of penetrating such front armor.

Of course, no explosives whatsoever would ever be able to tear throw such front armor of a tank either (except only a hollow-charge shell which would still not be able to tear a complete piece of such armor, but only to burn some narrow hole through an armor plate).

Considering that the Twin Towers' steel frames consisted of double-walled steel columns that were almost trice as thick compare to the T-34 tanks' front amour, it would not be possible to find any solution to break such columns simultaneously in many spots in order to achieve an "implosion" effect - the basic goal of any controlled demolition.

It was, of course, technically possible to break some of these columns in certain spots, using exceptionally huge amounts of hollow-charges attached to each individual column, but even such an incredible solution would not help to achieve the desired "implosion effect".

The Towers were simply too high and too rigid - their steel cores would have been simultaneously broken in too many spots on every floor, which no one could afford.

And even if they could, still, such a solution would not lead to the desired effect - there would not be any guarantee that such a high-raised structure would fall strictly down to its foot print - it might as well scatter its debris as far as a quarter of a mile, considering its mere height.

So, it was impossible to bring the WTC Towers down by any kind of traditional controlled demolition.

The same thing could be said about the WTC building # 7 and of the Sears Tower in Chicago. Either of them was constructed using similar thick double-walled steel frame that was impossible to break at once due to reasons described above.

However, in accordance with the US laws governing construction of skyscrapers buildings designers had to submit some satisfactorily demolition project before their construction project could be approved by the Department of Buildings. No one could be allowed to build a skyscraper that can't be demolished in the future.

This is the main point of the skyscrapers' in-built nuclear demolition features.

Ironically, such a nuclear demolition scheme of a skyscraper is not meant to actually demolish the respective skyscraper, especially considering that no one has any practical experience in demolishing skyscrapers by such means - it is only intended to convince the Department of Buildings to permit the skyscraper's construction whatsoever.

It appears that all designers and proponents of such nuclear demolition schemes sincerely hope that their ideas would not be put to use during their life-time.

Anyhow, "Controlled Demolition Inc." began to study possibilities of demolishing modern skyscrapers by underground nuclear explosions at the end of 60s, at request of the then New York Sate Governor Nelson Rockefeller - when it became necessary to get a legal approval from the New York Department of Buildings for the WTC Twin Towers construction.

After some research, a final solution was found and approved by the Department of Buildings and "Controlled Demolition Inc." got its nuclear demolition know-how patented.

Part 3. How does a modern nuclear demolition work?

First of all, such a modern nuclear demolition has nothing to do with the former atomic demolition using SADM or MADM as described above.

It is an entirely new concept. During modern nuclear demolition process, a demolition charge does not produce any atmospheric nuclear explosion - with its trade-mark atomic mushroom cloud, a thermal radiation and an air-blast wave. It explodes quite deep underground - much in the same sense as any nuclear charge explodes during a typical nuclear test.

So, it does produce the following:

• neither any air-blast wave
• nor any thermal radiation
• nor any penetrating radiation
• nor any electro-magnetic pulse

It could cause only relatively minor harm to surroundings by an ensuing radioactive contamination, which, nonetheless, considered being a negligible factor by designers of such demolition schemes.

What is a basic difference between an atmospheric and an underground nuclear explosion?

The basic difference is this. During an initial stage of a nuclear (as well as a thermo-nuclear) explosion, its entire explosive energy is being released in a form of a so-called "primary radiation" that in its main part (almost 99%) falls within X-rays spectrum (and remaining part is represented by gamma-rays spectrum that causes radiation injuries and visible spectrum that produces visible flash).

So, this almost entire explosive energy represented by X-rays would be spent on heating of surrounding air at tens of meters around a hypocenter of such an explosion. It happens because X-rays can not travel too far, being consumed by surrounding air. 

Heating of this relatively small area around the nuclear explosion hypocenter would result in appearance of so-called "nuclear fireballs" that physically is nothing else than an extremely overheated air.

These nuclear fireballs are responsible for the two main destructive factors of an atmospheric nuclear explosion - its thermal radiation and its air-blast wave, since both factors result exclusively from high temperatures of the air around a nuclear explosion.

When it comes to an underground nuclear explosion, the picture is entirely different.

There is no air around a small "zero-box" a nuclear charge is placed into, so an entire amount of energy instantly released by a nuclear explosion in a form of X-rays would be spent on heating of surrounding rock, instead. It would result in overheating, melting and evaporating of this rock. Disappearance of the evaporated rock would result in creation of an underground cavity, size of which directly depends on explosive yield of nuclear munitions used.

You can have an idea on how much rock could disappear during an underground nuclear explosion from the below table - where quantities of evaporated and melted materials of various kinds (in metric tons) are shown on "per kiloton of yield" basis:

Just as an example: detonation of a 150 kiloton thermo-nuclear charge buried sufficiently deep in granite rock would result in creation of a cavity measuring roughly 100 meters in diameter - such as the one shown in this picture:

WTC nuclear demolition idea.

 

Underground cavity after nuclear blast.

All skyscrapers have their lowest foundations lying 20-30 meters beneath the Earth surface.

So, it is possible to calculate a position of a "zero-box" under such a skyscraper in such a way that a nuclear explosion would produce a cavity upper end of which would not reach the Earth surface, but would reach only the lowest underground foundation of a skyscraper it intends to demolish.

For example, in particular cases of the Twin Towers of the World Trade Center in New York, their lowest underground foundations were 27 meters beneath the surface. While the 150 kiloton thermo-nuclear demolition charges were positioned as depths of 77 meters (measuring from the surface), or 50 meters below their underground foundations.

Such a thermo-nuclear explosion at a depth of 77 m would create an extremely overheated cavity with its upper sphere touching the lowest underground foundations of the Twin Tower it intends to demolish. But it would still be short of reaching the Earth surface by 27 meters - so surrounding structures would not to be affected by any destructive factors of this underground nuclear explosion (except by, possibly, only its radioactive contamination). 

The Tower that is to be demolished supposes to lose its foundations completely, and to be sucked-in into this overheated cavity, temperatures inside of which are deemed enough to melt the entire Tower. 

Nuclear demolition schemes of the WTC building # 7 and that of the Sears Tower in Chicago were calculated in the same way.

However, there is one more factor that is to be taken into consideration during calculation of nuclear demolition projects of skyscrapers. This is about the actual evaporated granite rock inside the cavity. Where all that former granite rock now in gaseous state supposes to go from the cavity? In fact, a picture of the physical events after an underground nuclear explosion is quite interesting.

Let's consider it.

Physical process during underground nuclear blast.

This pictorial rendition schematically represents all important physical processes during an ideally deep (means occurred sufficiently far from the Earth surface) underground nuclear explosion.

So, now it should become clear that an extreme pressure of the evaporated rock inside the cavity makes at least two important jobs:

1. it expands the actual cavity from its "primary" size to its "secondary" size

2. because it does this expansion at the expense of the neighboring areas of the rock, it produces two damaged zones around itself, each representing a different degree of damage

A zone immediately adjacent to the cavity in nuclear jargon is called a "crushed zone".

This zone could be as thick as a diameter of the cavity itself and it is filled with a very strange matter. Its filling is rock that is completely pulverized. It is reduced into a fine microscopic dust, an approximate particle of which is about 100 micron in size. Moreover, this particular state of material within this "crushed zone" is a very strange state - except after an underground nuclear tests it does not occurs anywhere else in nature. 

If you pick up a stone from this zone, but do so very gently, it might still stick together and still resemble a stone by its form and its color. However, it you only slightly press this "stone" with your fingers it will immediately crush into that complete microscopic dust it actually consists of. 

A second zone - next to the "crushed zone" is called a "damaged zone" in professional nuclear jargon. This "damaged zone" is filled with rock crushed to various pieces - from very small (millimeters in size), to some relatively big fragments.

As closer to a border of the "crushed zone", as smaller will be such debris, and as farther from hypocenter - as larger will be such debris. Finally, outside of the "damaged zone" border, there would be virtually no damage inflicted to surrounding rock.

However, we have considered above the physical processes which are true to an "ideally deep" underground nuclear blast.

When a nuclear charge is buried not sufficiently deep, a picture will be slightly different. "Damaged" and "crushed" zones will not be exactly round in the latter case. They would be rather elliptic - with their longer ends directed upwards - comparable with an egg facing upwards with its sharper end, or possibly even more ellipsoidal and sharper upwards than a typical egg.

It happens because the pressure of the evaporated gases would encounter the least resistance towards the Earth surface (since it is too near), so either "crushed zone" or "damaged zone" would extend upwards farther than to any other direction.

But when propagating upwards upper boundaries of the "damaged zone" and "crushed zone" encounter underground foundations of the Tower which is to be demolished, the picture would be even more different. It is because materials the Tower is built of differ from surrounding granite rock in a sense of resistance of materials. 

Besides, there is a lot of empty space inside the Tower, while the remaining granite rock towards the rest of directions (to either sides and downwards) is solid. So, expansion of the upper boundaries of "damaged" and "crushed" zones by the Tower's structure will be the farthest. 

In case of the WTC Twin Towers or the Sears Tower the "damaged zone" could likely reach up to 350-370 meters, while "crushed zone" that follows immediately, would likely reach up to 290-310 meters. But in case of the much shorter WTC-7 its entire length will be within the "crushed zone" - so it would be pulverized completely.

This ability of nuclear demolition to pulverize steel and concrete alike is one of its unique features.

The picture below shows an example of that fine microscopic dust that covered all over Manhattan after the WTC demolition. Many people mistakenly believed that it was allegedly "concrete dust". No, it was not. It was "complete" dust - mainly pulverized steel.

Despite common misconception, the WTC structures did not contain much concrete. Concrete was used only in some limited quantities to make very thin floors slabs in the Twin Towers construction. It was not used anywhere else. The major part of the WTC Twin Towers was steel, not concrete.

So this finest dust was in its major part represented by steel dust accordingly.

Though, it was not only "steel dust" alone - it was also a "furniture dust", "wood dust", "paper dust", "carpet dust", "computer parts dust" and even "human dust", since remaining in the Towers human beings were pulverized in the same manner as steel, concrete and furniture.

Dust from the WTC pulverization.

Some people might wonder - why the WTC-7 collapsed to its footprint very neatly, in its entirety, while either of the Twin Towers crushed down scattering not only dust, but even some debris to quite large distances.

This question is very easy to answer - you have to look at the distribution of "crushed" and "damaged" zones along the Twin Towers structures and the answer will become obvious.

The picture below represents an approximate distribution of damages in case of a nuclear demolition of a skyscraper using a 150 kiloton thermo-nuclear charge positioned 50 meters deeper than the lowest underground foundations of a skyscraper.

Don't forget, that demolition charges in this particular case were buried not "ideally deep", that is why forms of the "crushed" and "damaged" zones were not "ideally round" either - they were elliptic, with their sharper ends facing upwards - towards areas of the least resistance.

Nuclear demolition scheme.

This particular distribution of damages along the skyscrapers structures inflicted by such a process could be better understood when you watch videos (below in Part 4) showing details of collapses of the WTC Twin Towers and the WTC-7.

It should be added also that despite an apparent insufficiency of 150 kiloton thermo-nuclear charges to pulverize the tallest skyscrapers in their entirety, charges of higher yields could not be used in nuclear demolition industry due to merely legal reasons.

The problem is that in accordance with the USA - Soviet so-called "Peaceful Nuclear Explosions Treaty of 1976" yield of nuclear munitions used for non-military purposes was limited to 150 kiloton/per individual nuclear explosion and to maximum of 1.5 megaton aggregate yield for group explosions. So, the nuclear demolition industry has to fit into these legal frames: in case of the WTC demolition it was possible to use as many charges as necessary, but not in excess of 150 kiloton per charge.

That is why the WTC nuclear demolition scheme consisted of three of such charges - with aggregate yield of 450 kiloton.

For those people who have difficulty to imagine how powerful 150 kiloton is, it could be reminded that an atomic bomb dropped on Hiroshima in 1945 was less than 20 kiloton.

As it was mentioned in the beginning, this article does not describe any nuclear demolition scheme of a particular building in any exact detail, but does it rather on a conceptual level. But there is another article that describes a nuclear demolition scheme of the World Trade Center in New York in particular.

Nuclear Demolition Wikipedia

from Nuclear-Demolition-Wikipedia Website

This web site was created only to host one Wikipedia article that was removed by watch-dogs of the allegedly "free" Wikipedia.

It does not provide any further information except repeating the former Wikipedia article "as is". It allows also downloading the original Wikipedia's article on nuclear demolition that was, fortunately, saved in two formats - CHM and PDF - prior to its removal and as such it still exists even in its "original" Wikipedia form.

Please, use menu options on the left side to read the original article or to download it.

A brief history of that unfortunate article is as follows:

As it is suspected by many, the three World Trade Center buildings in New York (the WTC-1, WTC-2, also called the "WTC Twin Towers", as well as the WTC building #7) were intentionally demolished on September 11, 2001.

However, practically no one could satisfactorily explain true demolition mechanics behind the WTC unexplainable collapses at near freefall speeds amidst clouds of strangely finely grounded steel - during the WTC demolition its entire former core- and perimeter columns became nothing but strange microscopic dust.

Understandably, no reasonable person would ever reconcile himself with the strangest notion put forward by an infamous "9-11 Commission Report" that claimed the WTC Twin Towers collapsed due to their steel cores being melted by "kerosene" (especially considering the fact that the WTC-7, which collapsed after 5 PM the same day, was not hit by any "terrorist plane" and no "kerosene" was available to cause its collapse in the same manner).

Yet on the other hand, there are many conspiracy theories that claim the WTC demolition was due to alleged "explosives", alleged "thermite" (or due to some combination of the two).

There were even attempts to blame the WTC demolition on certain portable nuclear munitions (aka "mini-nukes") - akin to those used against the American Embassies in Kenya and Tanzania in 1998 on the anniversary of Hiroshima bombing. But, honestly speaking, neither of these conspiracy theories (including the "mini-nukes theory") could provide us with any satisfactorily explanation as to the mechanics of the WTC collapses.

Everyone could see it in widely available movie-clips that the entire steel structures of the WTC Twin Towers (as well as those of the WTC-7) were almost instantly reduced to strange microscopic dust and in result these most rigid structures in the world managed to collapse in near free-fall as if under them were not any remnants of incredibly thick double-walled steel perimeter- and core columns, but only an air alone.

Of course, even though the WTC Twins' and the WTC-7 collapses were truly strange, they were still explainable from technical point of view. In fact, there is nothing totally unexplainable in This World and all what you need - is just to find some suitable explanation using an ancient principle: "seek and ye shall find".

I was formerly a commissioned officer in the so-called "military unit 46179" also known as the Soviet nuclear intelligence and it so happened that I knew from my former service about in-built thermonuclear demolition scheme of the World Trade Center in New York. In fact, I knew about the WTC nuclear demolition project long before it was implemented on the 9/11.

To be honest, I got really tired of reading all those never-ending stories and conspiracy theories in regard to the September 11. That is why eventually I decided to make my own humble contribution to common efforts to find the truth about the WTC demolition.

I opened a few web sites dealing with this topic - including http://www.nuclear-demolition.com, http://www.911books.net, and http://www.3truth911.com - where I explained quite a lot of things regarding the 9/11. Since then I had a lot of requests from my visitors to publish some truly "academic" looking article in regard to the nuclear demolition concept (as a general concept, unrelated to the actual nuclear demolition of the WTC) and to make it available on Wikipedia.

Following these requests, I decided to create an article for Wikipedia - this time completely "neutral" - as it is suggested by Wikipedia's own rules.

I described the nuclear demolition concept only as a "concept" - without making any attribution to the WTC in New York or to the Sears Tower in Chicago. All I did - I explained in it how to use a huge 150 kiloton in TNT yield thermonuclear charge for demolishing a single skyscraper without annihilating its entire surroundings. In fact, that Wikipedia article of mine did not contain even a single mentioning of the WTC demolition on 9/11, it did not even hint that such a concept had anything to do with the World Trade Center buildings.

Moreover, in that article it was not mentioned at all that such a nuclear demolition idea had anything to do with the United States in particular - the article was purely technical and it could be as well understood that such a concept could be implemented in any "nuclear" state - ranging from the former Soviet Union to India and Pakistan.

If you read the original article - you will find a confirmation of my words - the article is indeed purely technical. No politics, no "conspiracies" is involved.

Nonetheless, it did not take too long for the watch-dogs of the allegedly "free" Wikipedia to accuse this article of being just another "crazy 9/11 conspiracy theory". Immediately this article was removed from Google search index (so that no accidental Internet user might encounter it by searching for "nuclear demolition") and after a few days it was removed from the Wikipedia whatsoever - following some purported "democratic removal procedure" that is traditionally used in the "free" Wikipedia to remove unwanted contents without being accused of "censoring".

Altogether this article managed to survive in the Wikipedia only 4 days in completely free access and for just another extra week during the "democratic removal procedure" during which it was cut off from any search engine and all access to it was restricted to only Wikipedia's own watch-dogs.

To be completely honest, there were two guys who said "yes" - "keep this article" during the "democratic removal procedure", but it did not help - the absolute majority was to remove it. I guess you will understand why it had to be removed after reading the actual article.

So, the "collective decision" was to completely remove the "nuclear demolition" Wikipedia article and, to prevent any possible future "abuse" of these seditious words, to re-direct forever any search by "nuclear demolition" keywords to another Wikipedia article dealing with the so-called "Peaceful nuclear explosions".

And so it was done. You can no longer create any Wikipedia article under "nuclear demolition" words. It is not technically possible.

However, it is technically possible to either read the contents of the former Wikipedia "nuclear demolition", as well as to download the original Wikipedia article saved in either CHM or PDF format "as is" from this web site. Please, use buttons on your left to get to a needed option.

I guess that despite the actual article does not say straightly that this nuclear demolition concept has anything to do with the WTC Twin Towers or the WTC-7 collapses and it did not even imply such a thing, you can still get its main point.

Thank you for your attention.
