ORIGINAL: EverLearning And with just a minutes time your post above is negated as a mischaracterization of what NIST actually said: quote:
Some 200 technical experts—including about 85 career NIST experts and 125 leading experts from the private sector and academia—reviewed tens of thousands of documents, interviewed more than 1,000 people, reviewed 7,000 segments of video footage and 7,000 photographs, analyzed 236 pieces of steel from the wreckage, performed laboratory tests and sophisticated computer simulations of the sequence of events that occurred from the moment the aircraft struck the towers until they began to collapse. Based on this comprehensive investigation, NIST concluded that the WTC towers collapsed because: (1) the impact of the planes severed and damaged support columns, dislodged fireproofing insulation coating the steel floor trusses and steel columns, and widely dispersed jet fuel over multiple floors; and (2) the subsequent unusually large jet-fuel ignited multi-floor fires (which reached temperatures as high as 1,000 degrees Celsius) significantly weakened the floors and columns with dislodged fireproofing to the point where floors sagged and pulled inward on the perimeter columns. This led to the inward bowing of the perimeter columns and failure of the south face of WTC 1 and the east face of WTC 2, initiating the collapse of each of the towers. Both photographic and video evidence—as well as accounts from the New York Police Department aviation unit during a half-hour period prior to collapse—support this sequence for each tower. Also from that article quote:
However, when bare steel reaches temperatures of 1,000 degrees Celsius, it softens and its strength reduces to roughly 10 percent of its room temperature value. Steel that is unprotected (e.g., if the fireproofing is dislodged) can reach the air temperature within the time period that the fires burned within the towers. Thus, yielding and buckling of the steel members (floor trusses, beams, and both core and exterior columns) with missing fireproofing were expected under the fire intensity and duration determined by NIST for the WTC towers. Shucks. I hate facts, don't you?[sm=hammerhead.gif] Yeah, me too... Here's three good ones... 1. Rumsfeld under direct order from the W. House, changed the engage protocol at NORAD, just 6 months prior to 911. Under the new protocol, NORAD had to seek specific permission from Bush, Cheney or Rummy before engaging any stray or unidenified aircraft. 2. Under Executive Order from the W. House, VP Cheney was given all access to NORAD for the purpose of conducting war games. This, just 6 months before 9/11 and despite opposition from Congress and other key members within the US Govt. This is clearly not the VPs job. 3. On the morning of Sept 11, Cheney was conducting war games at NORAD with simulated drills of airliners being crashed into THE WORLD TRADE CENTERS and various other aviation war games drills in the east. Google: Vigilant Guardian or Northern Vigilance for more info. This is clearly not the VPs job also. But, these are all just silly facts/coincidences, right? Wrong.
