But regardless sporadic office fires and asymmetrical damage does not cause global collapse of buildings into their own footprint. There is only one
way that can happen...
Pic of a perfect controlled demo of a building...
This is a building after asymmetrical damage from a bomb...
It's not building design it's physics, and WTC 7 defied the laws of physics by collapsing into the path of most resistance without any
friction/resistance from undamaged building structure. For that to happen all columns would have to fail at the same time, otherwise you would end up
with a steel burned out shell and a partial collapse.
There is only one way a building will fall straight down and that's if all the columns fail at the same time, and that doesn't happen unless it was
Anok... This is the Northside of WTC7.... where most truthers claim that there was no damage and or fires. If you watch the videos, there are MANY
vehicles on the street that were damaged by fire and or debris.
Yes the photos you posted are of a building fully engulfed in flames.
Again...these are of the NORTH side of WTC where you can see a substatial amount of fire.
No one has been able to prove that WTC 7 came down with anything but controlled
How does a 47 story building collapse without destroying building feet away?
No doubt about it, World trade center 7 was brought down by controlled demolitions.
Building 7's Rubble Pile
Less than seven seconds after Building 7 began to implode, all that was left of the steel skyscraper was a rubble pile. The rubble pile is notable for
* its location - It was centered around the vertical axis of the former building.
* its size - The pile from the 47-story building was less than two stories high.
* its tidiness - The pile was almost entirely within the footprint of the former building
What does the shape of the rubble pile indicate about the events leading to the collapse of building 7?
Consider the rubble piles produced by other collapses. The only examples of total collapses of steel frame highrises (excepting WTC 1, 2, and 7)
involved either severe earthquakes or controlled demolition.
Total collapses due to earthquakes are extremely rare. The rubble piles of the few documented cases had none of the above features. 1
Total collapses due to controlled demolition generally have all of the above features. In fact, to achieve such a small, consolidated rubble pile is
one of the main objectives of a controlled demolition. www.wtc7.net...
Great, we all agree that WTC 7 was controlled demoltions.
Anyone care to entertain us with their wild idiotic, tabloid type of conspiracy on how World trade center 7 was brought down with anything but
I'm somewhat weary of this. Anyone who has seriously studied WTC 7 has seen all these videos many times already.
First the topic title - MASSIVE fires. The fires don't get bigger by using capitals. Relative to many high rise fires they were both small and of
short duration and were limited to the 11th and 12th floors.
Second - what difference does the size of the fires make? Big fires don't cause steel high rises to implode any more than small ones.
A basic knowledge of physics, construction engineering and the history of steel framed skyscrapers tells us they can be severely damaged by fire; that
a fire burning hot and long enough can cause partial collapses (see Windsor Tower). It's not clear how much damage a fire could do to the central
support structure of one of these towers if it was allowed to burn indefinitely. I assume there would be insufficient heat and fuel to have much
effect upon it. There is no example of a high rise being gradually raised to the ground in this way.
More relevantly, we have no historical precedent (unless you count WTC 1, 2 or 7) nor any known physical mechanism for a fire (however severe) causing
a high rise to implode (i.e. collapse precipitately and globally).
Compare and contrast:
47 floor WTC 7
Fire on Sept 11, 2001
Duration 6 hours
38 floor Meridian Plaza, Philadelphia
Fire on Feb 23, 1991
Duration 19 hours
Was later demolished floor by floor with explosives.
56 floor Caracas Tower, Caracus
Fire on Oct 15, 2004
Duration over 17 hours
Sprinklers and standpipes reportedly did not function, due to poor maintenance. The intensity of the fire prevented firefighters from reaching the
tower's upper floors. No floor beams collapsed.
Engineers who inspected the building's structure when the fire was out reported that it was "very solid."
32 floor Windsor Tower, Madrid
Fire on Feb 12, 2005
Duration almost 24 hours
This is what remained. The steel core did not disintegrate, but had to be disassembled column by column.
47 floor Al Salam Tecom Tower, Dubai
Fire on May 14, 2008 (tower was under construction)
Duration almost four hours
Construction continues on the tower.
I'm interested in knowing why on page 1 they state that FEMA and NIST formed a team to analyze WTC 7. Then they state that "the effort began with
the collection of structural pieces". Hmm....that's not what NIST themselves say.
No steel from WTC 7 has been identified from the pieces of recovered WTC steel in NIST’s possession.
