SHOCK-WAVE EXPLANATION FOR THE FIRST BASEMENT EXPLOSION DEBUNKED:
In Mark Roberts paper the explanation for the first basement explosion is a jet fuel deflagration or what is commonly refered to as the fireball hypothesis
The descriptions of explosions in the basement levels are entirely consistent with jet fuel traveling down the elevator shafts

This explanation has been proven to be
physically impossible because the first basement explosion occured
below car 50 and
before it reached the B1 basement level. That means for the official explanation to be true, whatever exploded below car 50 and before it reached B1, it had to travel down 90+floors from the impact zone and pass elevator car 50 undetected. But since elevator car 50 only had to fall approximately 17 floors at the speed of gravity until the breaks were applied and given that the fireball produced upon impact was estimated by NIST to be expanding at 28m/s we can safely conclude that a fireball from the impact zone with
that velocity could not have possibly reached car 50 let alone manage to pass it and then explode! Furthermore to believe in this fantazy one has to believe that a raging fireball could pass car 50 literally undetected by the passengers within car 50. Of course no debunker in the JREF forum can convincingly address these problems, they are unable to face the reality that the official fireball explanation is impossible and even less able to debunk my argument that
proves its impossible.
But there are some truly objective minded individuals in the JREF forum, Norseman for instance, recognizes the fact that the fireball could not have passed car 50
My view has always been that the jet fuel fireball arrived after elevator car #50 reached B1/B2.
Now the obvious implication of this view is that Norseman must provide another explanation – other than
the official explanation - for the first basement ‘explosion’ and in this post I will debunk Norsman’s latest explanation for this event. But before I continue it is worth pointing out that in relation to the first basement explosion Norsman’s explanation has been anything but consistent. First it was a (i) “fireball” (post#1), then it was (ii) “falling debris” (post#269), and now its a (iii) “shock-wave” (post#561). Of the three explanations a shock wave travelling at 4500m/s most certainly could have passed the falling elevator before it reached B1. But would it ‘
sound’ like an ‘explosion’ to those individuals on B1 and B4?
Norseman writes
“The impact shock wave would reach B1 instantly. Felipe David would hear the impact sound transferred through the core columns”.
I agree that when the plane struck the steel core columns
vibrations travelled right down the length of the core. It is a known fact that every vibrating object has a
resonant frequency determined by its physical parameters such as its thickness, length etc. For example, consider a tuning fork, a longer heavier tuning fork when struck will produce a lower frequency than a shorter lighter tuning fork. Accordingly, a typical garden fork due to its thickness and length etc will produce an even lower frequency when struck.
Now I cant say exactly what the resonance frequency of a steel core column is but I can say with all certainty that, due to their thickness and length, that the core columns would have produced a low frequency wavelenght. But here is the problem:
all explosions produce high frequency wavelenghts therefore whatever caused the explosion Felipe David and many others heard in the basment
could not possibly have been caused by a shock-wave passing through a core column because vibrations passing through core columns DO NOT SOUND ANYTHING LIKE EXPLOSIONS.
To support this claim I found a website that lists many various sources of explosions, but to my astonishment there was no example of a vibrating steel core producing the sound of an explosion!!

But there are other problems with the shockwave explanation. The shock waves travelled through the length of the entire core column, that is from the impact zone right down to basement level B6. Norseman claims that these vibrations would sound like an explosion (although impossible let us assume this to be true). But how come nobody on B6 heard an explosion? How come those on B4 heard an explosion
above them and those on B1 heard an explosion
below them (a fact entirely consistent with the detonation of an explosive device on level B2/3)? And how come
“13 (non-deaf) people on 12 levels below the impact zone didn’t hear the aircraft impact/explosion on their building”
http://911stories.googlepages.com/insidethetowers:summaryofwitnessaccounts
If indeed vibrations travelling through a steel core column could sound like an explosion then everyone should have heard the explosion because if I am not mistaken the core columns ran
the entire length of the building.
Now its a known fact that
all shockwaves decrease in energy over distance and time so it violates basic laws of physics to suggest that 13 non deaf individuals only 12 floors below the plane crash did not hear the sound of an explosion
generated from the vibrating core columns yet individuals 90+ floors below heard the sound of an explosion
generated from vibrating core columns?
So to believe Norseman’s latest fantazy one has to believe that these shock waves passed SILENTLY over some floors then INCREASED IN ENERGY OVER DISTANCE AND TIME and magically manisfested from a low frequency wavelength into a high frequency wave length!! Frankly this explanation is ABSOLUTLY absurd and if you are unable to
counter the above reasons then the rational thing to do would be to abandon your current explanation for the sound of the
first basement explosion and seek perhaps a less fantastic alternative my friend.
