Again: WTC 7 is the key. Steel buildings don't just fall on their own... or by fire...
Exactly so. No steel building has ever
failed as a result of fire, either before or after 9-11. I think that one of the red flags was raised by the 9-11 Commission itself regarding the towers' collapses: on Page 541 of the Commission's Report, they state that "the outside of each tower was covered with a frame of 14 inch wide steel columns...these exterior columns bore most of the weight of the building. The interior core of the building(s) was a hollow steel shaft in which elevators and stairwells were grouped
. This statement, for an official government inquiry into the worst manmade disaster in US history, is either mind-bogglingly incompetent, or a deliberate lie. I suspect the latter, because the entire premise of the governments' claim that the buildings collapsed into their own footprint in a "pancake" type fashion would be severely compromised should they have stated the reality of the towers' interior core which consisted of 47 massive steel columns, 36" by 14" at the base, with 4" thick walls.The buildings were greatly over-engineered with multiple structural redundancies, and were capable of supporting up to 10 times their actual weight.
... even with jetfuel fires
The majority of the jetfuel burned off in the initial fireball (especially in the case of "Flight 175" hitting the South Tower). According to NIST, no evidence was found that indicated temperatures higher than approximately 500ºF in the steel. The highest possible temperature attainable by burning kerosene in the most optimum conditions (in pure oxygen, maximum efficiency combustion) is about 1800ºF. The fires in the WTC, as evidenced by the clouds of thick billowing black smoke, were low efficiency and oxygen starved, and it is considered extremely unlikely that the temperatures attained by those fires were anywhere near the theoretical maximum. Structural steel melts around 3000ºF. Another point is that the most efficient combustion of jetfuel occurs in jet engines .. steel parts which have been employed in jet engine construction do not melt in midflight. (!)
Recently, however, steel samples sent to Prof. Steven Jones at Brigham Young University from several monuments fabricated from ex-WTC steel have been analyzed, and products of thermite and thermate (thermite with added sulfur) reactions have been found. See paper here
These findings appear to be logically sound, especially considering the fact that satellite-based thermal imaging found that there were hotspots of molten material for weeks after the attacks
, even underneath WTC #7, which was not even hit by an airplane.
Dr. Jones' paper has been favorably peer-reviewed twice
at two different universities. The integrity of the samples from the WTC steel was maintained from collection to analysis, and contamination was ruled out because the analyses were performed on all parts of the samples, including internally
from sliced sections.
Dr. Jones and team did the math and the chemistry. Now it's up to law enforcement to find out who set those probable thermite/thermate charges. Did "al qaeda agents" get in there and take advantage of the lax security in the buildings (which happened to be provided by Securacom, a company which just coincidentally, provided security at two of the airports from which the rogue flights originated, and on whose board of directors sat President Bush's brother Marvin Bush? Persons unknown, either al qaeda or not, might have been prepping the building during the several power and access shutdowns which happened during the weeks leading up to the attacks.
