I have a hard time not believing the experts who spent years studying the collapse of wtc7.
Who spent years ...STUDYING?...more like 'THINKING' of a way that, FIRE alone could have done it...and they FAILED
BTW...the WTC7 report is a HYPOTHESIS....
a 'hypothesis' that has NO supporting facts...
NO steel was examined or even saved...ALL material destroyed
NO evidence of an 'INFERNO' that WOULD be needed to heat ALL the vertical support. EVENLY, to get the result of EVEN DECENT OF THE ENTIRE STRUCTURE,
that WE SEE in EVERY video of 7 collapsing.....ALL video and picture evidence show ONLY spot fire, NEVER on more than 2 floors, and NEVER covering an
ENTIRE floor....
They rely on HEARSAY for the amount of fire for their HYPOTHESIS.....and they IGNORE hearsay, about EXPLOSIONS and BOMBS going off..
[NCSTAR1A-3.2]"It is likely that much of the burning took place beyond the views of the windows"
[NCSTAR1A-3.2]
"The fires were fed by ordinary office combustibles"
There are NO pics of ANY FIRE in the NIST WTC7 report to support their HYPOTHESIS
NO mention of free fall ACCELERATION in their peer-reviewed draft from 8-08
Shyam Sunder, lead investigator for the NIST was confronted at a NIST Q&A BEFORE the final report came out...as to WHY, NO mention of free fall
ACCELERATION in the peer reviewed draft, when it is so easily measured by the facade of the
building...
here is the vid of him stumbling for an answer.
and he also says that..."free fall acceleration can ONLY occur when there is NO STRUCTURAL COMPONENTS BELOW IT"
and here is what NIST was forced to put in the final report...
[NICSTAR 1A 3.6]"constant, downward acceleration during this time interval. This acceleration was 32f/s^2,(9.8m/s^2), equivalent to the acceleration
of gravity.
This free fall drop continues for approximately 8 stories or 32 meters,(105ft.), the distance traveled between t=1.75s and t=4.0 s.
when this occurs, the kink forms and the ENTIRE building is EVENLY falling
WE SEE IT happening...falling as fast as an object falls...THROUGH THE AIR
(actually, what they measured, should ONLY occur in a vacuum...with NO resistance...when a feather falls as fast as a marble...THAT is what falling at
a rate equivalent to the acceleration of gravity is).
HOW CAN THIS HAPPEN?
as soon as the kink is formed, the HVAC, 'other' Penthouse, roof, facade, within 0.5 seconds from each other, have free fall ACCELERATION for
100+ft. ALL support was INSTANTLY taken away, AS WE SEE by the EVEN decent
if there was a progression from east to west
WE WOULD SEE IT
the roof WILL NOT support itself while columns fail below it. the facade is a non supporting structure, and IS attached to the perimeter columns it
will not stand while the columns fail behind it.
how do you get,'EVERY' column to act the same way, at the same time, unless they are under the 'SAME' conditions, and acted on by the 'SAME'
force???
At 4.0s of the collapse, the 'ENTIRE' building is falling faster than 80 ft.a second...'ONLY' possible by removing 'ALL' resistance...nothing in
the way
just as Shyam Sunder says..."free fall acceleration can ONLY occur when there is NO STRUCTURAL COMPONENTS BELOW IT"
