Hello.... a strange game this 9/11.
There is no conspiracy theory or any other kind of theory, speculation or guesswork required when it comes to arriving at a conclusive determination of fact with regard to WTC7 (or by extension the rest of the events that day) because there is
no debating Newtons Law of Conservation of Energy as applied to a falling body (or building). The matter was settled the day David Chandler faced down the NIST on the issue of gravitational acceleration....
WTC7 - ANALYSIS AND CONCLUSION
A complete Empirically Verifiable Scientific Method Driven Graphical Target System
Analysis and Conclusion arrived at by Process of Elimination.
The conditions required for gravitational acceleration
to occur have been known for centuries....

The condition under which a body is, literally, free
to fall under the influence of the local gravitational field
with no resistance to its acceleration....

The control that appears on the right in many of the
animations is intended as a reminder of that, and also
signals the beginning of a comparison....

We can still know with certainty what conditions exist
beneath an object as it falls....

....even though we may not be able to see into the
space beneath it as it does....

Buckled columns, whether one or a hundred, whether one
at a time or all at once (or any combination thereof) won't just go
from 100% to 0%
when they buckle, they'll steadily
decrease in strength
while they buckle and that takes
time....

The mechanism of buckling, a mode of natural progressive
structural failure, whether caused by heat....

....by overloading....

....or even other modes of natural progressive structural failure
such as impact induced fracturing....

....or fracturing due to overloading....

....
absolutely can not match or create the conditions required for gravitational
acceleration to occur, it's literally impossible. There is no such
thing as
structural gravitational acceleration....

Some force must be introduced to quickly remove all support from
beneath the literally falling visible upper part of the building seen
in the video. The claimed
progressive collapse of the building
(NIST probable collapse sequence starting with column 79 on the left)....

....that essentially happens
all at once....

....is
clearly physically inconsistent with what we
empirically
know of natural progressive structural failure (defined as a time
consuming process of individual/sequential/simultaneous failure
involving one or a number of related structural components). It's
a
physical impossibility for the lower part of the
asymmetrically damaged building (reportedly three core
columns and nine perimeter columns)....

....to have naturally progressively collapsed in
any way that
could result in the upper part of the building
symmetrically descending straight down through itself (NIST probable collapse
sequence starting with column 79 circled below) at anything
near gravitational acceleration for
any period of time....
Any scenario like that playing out below resulting from natural
progressive structural failure including a 105 foot 2.25 second period of
gravitational acceleration is an
absolute physical impossibility....

....and there is
absolutely no mode or combination of modes of
natural progressive structural failure driven
solely by gravity that
can
ever give rise to the conditions required for free fall to have
occurred at
any point during it's descent....

The scenario playing out below is an
absolute physical impossibility.
Just as there is no such thing as
structural gravitational acceleration, nor is there any
failure mode known as
natural progressive structural gravitational acceleration....

There is simply no point during a natural progressive gravity driven
collapse of any steel frame skyscraper where one could say....
"Hold it.... right there! That's the point where all the steel columns
and structural components that were supporting the building just a
moment ago (with an area greater than that of a football field)
will undoubtedly be found to be behaving in a manner very much like
air (below left). It will take very careful calculation to tell the fall
times apart during this free fall period of the ongoing natural
progressive structural failure (below right)"....
For the 2.25 seconds (eight stories, approximately 105 feet) that we
know the upper part of the building
literally fell at gravitational
acceleration it
cannot have been using
any of it's potential
energy to crush the building contents, columns and other structural
components beneath it and undergo free fall
at the same time (as
illustrated by this frangible impedance scenario)....

It's
physically impossible for the lower
asymmetrically damaged part of the building to have naturally progressively collapsed
in a way that could result in the upper part of the building actually
accelerating as it descended
symmetrically straight down through
itself, through the path of maximum resistance (below right), and then,
driven on
solely by gravity, actually
continue to accelerate so
nearly to gravitational acceleration (below left) as to require
very
careful calculation for any difference between the two to be detected....

Some
other force powerful enough to quickly remove
all support
from beneath the upper part of the building as it descended
must
be introduced to explain the observed rate of descent during the 2.25
second period of gravitational acceleration. For the 2.25 seconds that the
building
literally fell at gravitational acceleration, no
other force
powerful enough to quickly remove
all support from beneath the
upper part of the building was seen to be introduced from
outside the building, and no
other force powerful enough to quickly remove
all support from beneath the upper part of the building is known
to have existed
inside the building as an element or normal
function of it's infrastructure. For a load supported by a column to
descend at gravitational acceleration, all support
must be quickly
removed, there's
absolutely no other way. It
must be knocked
out, pulled out, blown out, vaporized etc. Since no eight story tall
boulders were seen rumbling through Manhatten that day that could have
quickly
knocked out all support....

....and no suspicious looking Frenchmen were spotted rigging for verinage
(a form of controlled demolition) the night before that could have
quickly
pulled out all support....

....and no bombs or rockets were seen to be dropped on/fired at it that
could have quickly
blown out all support....

....and no giant laser beams or other secret weapons were being tested in
the area that could have quickly
vaporized all support....

....and no
other force capable of quickly removing all support from
beneath the upper part of the building existed in the building as a
normal function of it's infrastructure (blue)....

....it
naturally follows that whatever the
other force was that
must be introduced to explain the observed 2.25 seconds of descent
at gravitional acceleration, it
must have been introduced some
time
before the event, and unless someone can show how the
other force that
must be introduced either
during or just
before the collapse of the building was introduced from
outside
the building, or that it was already existing
inside the building as
a normal function of it's infrastructure, the process of elimination really
leaves
only one possible explanation for the building's behaviour.
Some energetic material powerful enough to quickly remove all support
from beneath the upper part of the building during the 2.25 second period
of gravitational acceleration
must have been physically transported
inside the building some time
before the event, it
had to be
brought in. The explosion model is the
only one....

....that can
realistically match and empirically be
expected to
create the conditions that we
know must have existed....

....beneath the
literally falling visible upper part of the building
during its observed largely symmetrical descent at gravitational
acceleration for approximately 105 feet in 2.25 seconds....

The undisputed (both the NIST and independent researchers alike agree)
observation of a significant well defined period of gravitational acceleration....
Stage 1 (0 to 1.75 seconds): acceleration less than that of gravity (i.e., slower than free fall)
Stage 2 (1.75 to 4.0 seconds): gravitational acceleration (free fall)
NIST - "During Stage 2, the north face descended essentially (displaying all the absolutely
necessary, extremely important features) in free fall (free descent of a body in which the gravitational force is the only force acting on it), indicating negligible (so small or unimportant as to be not worth considering, insignificant) support from the structure below."Stage 3 (4.0 to 5.4 seconds): decreased acceleration, again less than that of gravity

....means that an explosion, or a number of explosions,
must have
occurred that was powerful enough to quickly remove
all support from beneath the upper part of the building (below right), either all at
once or incrementally in advance of its descent, permitting it to descend
at gravitational acceleration for the observed period and under the
conditions required (below left) for free fall to occur....

The empirically established fact that WTC7 was brought down by
explosives immediately shines a bright spotlight on literally the
only
ones who could possibly have carried out a covert domestic operation
of this magnitude (all the events of that day).... the
only ones who
had exclusive 24/7 access to the highly secured building (WTC7).... the
only ones who were in complete control of the security system for
the building.... the
only ones who had ready access to the quantity
and quality of energetic materials required.... and the
only ones
who had the required expertise in the effective use of said energetic
materials. The fact is that
only the Department of Defense/Central
Intelligence Agency could've done it. And just as one needn't be Isaac
Newton to see there is no other possible explanation for the behavior of
WTC7 other than energetic materials having been physically transported
inside the building, one needn't be Sherlock Holmes to see there is no
other possible explanation as to who could have done it since the building
was in perpetual lock down for many years as a highly secured
government facility, it's elementary....
