The "spandrel beam connections" are steel elements, and they are on the perimeter of an structure that is not rigidly enclosed (has windows, open office spaces...). Are you suggesting that some source of expanding gas inside the tower would have "pushed" the spandrels and columns sufficiently to break those connections? It should be pretty easy to calculate the minimum pressure that can do this, and determine from there possibly blast scenarios.
However, in true explosive CDs of steel structures, it is never the "pressure volume work" that "pushes" the steel element appart (that's what certain types of bombs do in military applications) - it is the shockwave wiithin the steel, produced by a supersonic explosion in direct contact with the steel, that shatters it. This is much more efficient than bombs. A few ounces of high explosive placed smartly on the steel does easily what a hundred pounds of a gas-expanding bomb blast do if detonated away from the steel members.
And we both know how awesomely, insanely loud the ounces of CD explosives go BANG in real CDs.
Bombs, on account of being much larger, are louder.
The source of the force exerted by both bombs and explosive CD charges are "
explosives", not? I had asked you
What is the source of the force that moves the material that constitutes these expulsions?
And you apparently picked this option as your answer:
A) Demolition charges
I then asked:
If your answer is A), why then can't you acknowledge that you are talking about explosives?
It seems bleedingly obvious that any "
demolition charge doing pressure volume work" would be powered by some kind of "
explosive" - by definition, Tony!
Why could you not make yourself say that? You implicitly claim "
explosives", but at the same time seem to doubt your own claim!?
Anyway - before you gave your vague answer,
I had presented you with 6 points, of which you addressed only one (number [3]), and only vaguely. What about the others?
[1] Most truthers think "freefall" of the north wall is "evidence" for the instantaneous destruction of the WTC7 perimeter columns by explosives ober 8 stories. YOU, Tony, are one of the few truthers who realize that this is FALSE - that failure of the core could result in this freefall episode. So why do YOU bring this up?
[2] You fail to convince on that point here, and have continued failing for many years now.
[3] What do you claim those expulsions are? Explosions? Why are they not accompanied by extremely loud BANGs?
[4] Explosions do not create bulk amounts of molten metal, so it is a mystery, and has been for many years, why truthers are so married to the idea that the ALLEGED presence of molten steel (you must know very well that there is no ACTUAL evidence for bulk amounts of molten steel) has anything to do with a "controlled" demolition. Be the first truther in your universe to explain how any feasibly method of demolition would result in bulk amounts of molten steel long after the debris came to rest!
[5] "Symmetry" is a mantra. There is no actionable metrics to determine whether or not a given collapse is "symmetric", and there exists no reasoned argument why symmetry is impossible for a fire-induced collapse. You are appealing to the layman's "common sense". Haven't you heard the bon mot, sometimes attributed to Albert Einstein, that "common sense is the sum of the prejudices acquired by the age of 18"?
[6] "The" charges, Tony? Which? What kind? There were no explosions consistent in loudness, timing, number and brisance with CD, and there was no thermite, and there exists no theory that explains all of the relevant observations of the day with explosive or thermitic charges!
I had predicted:
And you must intimately know all of this, Tony. You will not rebut a thing I wrote with reasoned arguments!
And indeed, you did not rebut a single thing with reasoned arguments. You only addressed one point with a bare and vague assertion.
So many years, and you cannot argue a thing, Tony! Isn't it time to fundamentally reconsider your positions?
