*MESSAGE FROM THE THREAD STARTER*
This thread is for evidence and scientific discussions only. No supposition, no "why did they do it?", and especially no bullshit pictures intended to derail the thread. Present verifiable evidence or refute it with science. If you can't do that, you will go find another thread.
Ustwo, you're not welcome to post whatever you want in threads. There are rules on TFP and not following them along with disrespecting people tends to bring consequences.
So anyway, getting back on topic:
Let's take a closer look at WTC 7.
47 stories tall, trapezoidal shape from above, 610'H x 330'L x 140'W, steel frame, storage tanks containing diesel fuel, 12 transformers, an emergency bunker for Rudy, 1,868,000 sq ft of office space
Official collapse:
According to the official story, after the North WTC tower was hit it rained debris down on WTC 7 which caused substantial damage to the south face, particularly the bottom of the south face. There was also some damage to the southwest corner. Loss of power to an inadequate fire suppression system prevented sprinklers from putting out the small fires caused by the debris in the far south side of WTC 7.
After the North Tower collapsed, firefighters moved into WTC 7 in an attempt to put out the small fires. A fire was reported burning for several hours. At 5:20 the building collapsed completely, falling into it's footprint due to "weakening caused by fires".
Questions:
One must consider several facts when looking at the official story of FEMA and the NIST:
1) A steel framed building has never collapsed due to fire before 9/11. In 1991, One Meridian Plaza in Philadelphia had a 4 alarm fire which burned for 18 hours and literally destroyed everything but the frame across 8 floors did not cause any structural failures. WTC 7 fires were not 4 alarm and burned for around 7 hours. As a matter of fact, scientific experiments which use fires that burn hotter than any known building fire in history used on steel frames without fire protection cannot cause any level of damage to the steel frame.
Conclusion: fire alone is not likely to have caused a collapse at all, let alone...
2) A steel framed building falling at free fall speeds into it's footprint?
Please watch this gif very carefully. Please note that this has not been sped up at all. The middle of the building falls slightly faster than the edges (instead of the south, where the damage was reported) and the collapse happens only at the bottom, totally evenly.
Notice the break point?
Now look at the rubble:
The collapse was centered around the vertical axis, it's less than 2 stories high, and it's almost entirely in the footprint of the building.
3) The physical evidence was destroyed. Without being investigated as rubble, the steel from WTC 7 was sold off and was melted down. This is one of the 3 steel framed buildings in history to collapse due to fires, but it wasn't studied?
These are unanswered questions.
