That alone should raise eyebrows. I thought the claim was damage from the other buildings collapsing coupled with a diesel tank that was from emergency generators? Read the FEMA report. That's one scenario that they propose, but they state that their best models have an extremely low probability. They admit that they don't really know what was the mechanism. They also discount that the building acquired much damage as compared to other buildings nearby. You state that claim with much more certainty than the folks who propose it. http://www.fema.gov/pdf/library/fema403_ch5.pdf says there was a 6000 gallon diesel tank in the building between the 2nd and 3rd floors and a 275 gallon diesel tank (and an 11,000 gallon water tank on the 7th floor, that's a lot of weight on the supports under the 7th floor). An additional 100 gallons of diesel on the 9th floor and 275 gallons on the 8th floor. Those tanks were fed from fuel lines coming up from the 6000 gallon tank. How can you say they can't account for a fuel supply when there are 1000's of gallons of fuel in the building? "...It is important to note that floors 5 through 7 contained structural elements that were important to supporting the structure of the overall building. The 5th and 7th floors were diaphram floors that contained transfer girders and trusses. These floors tranferred loads from the upper floors to the structural members and foundation system that was built prior to the WTC7 office tower. ..." Now, they have photographic evidence that shows the south side of the building was damaged from the collapse of WTC1. They also say that "...a portion of that piping ran in close proximity to Truss 1" so if that diesel line was ruptured by debris from the collapse of WTC1, that could have supplied the fire. Now, if you go on a camping trip, try to crush a good quality can. Next take that can and put it inside your campfire and let it heat up for a few hours then try to crush it again... Steel is tempered by heat and reheating steel can remove the temper... Figure (or photo) 5-23 refers to "the kink", and that just happens to run across truss 1 (the same truss that the diesel line ran near... FEMA is right in stating they don't know for sure because they don't know for sure, but they do have sensible theories other than implying it was blown up by saboteurs unknown... When is the last time there was a fire in a highrise that was allowed to burn for 7 hours because the firefighters didn't have access to water because another building collapsed and severed the water supply? The simple fact is it's important to study because we don't normally let fires burn that long... -- John Nelson ----------------------------------------------------------------------------- Chicago Area Paddling/Fishing Page http://www.chicagopaddling.org http://www.chicagofishing.org (A Non-Commercial Web Site: No Sponsors, No Paid Ads and Nothing to Sell) |

The closest related instance I can come up with is One Meridian Plaza in Philadelphia in 1991. A smoke detector triggered at about 10:23 on Feb 23, 1991 on the 22nd floor. The fire burned through electrical cables as fire crews reached the 11th floor. All equipment had to be hand carried up 20 floors using only battery powered lights. Almost from the beginning, there were water supply problems, and firefighters had inadequate pressure and water flow to attack the fire as it spread upward to the 23rd and 24th floors. It wasn't until 2:15 a.m. that they managed to get a 5" line up one of the stairways. By 6 a.m. they'd gotten a third as far as the 17th floor when a sprinkler contractor adjusted pressure reducing valves on the standpipes to give firefighters near normal flows. By then, however, the fire had spread upward and could no longer be fought with manual hose systems. All firefighting operations were stopped shortly thereafter and the building evacuated at 7 a.m. due to the danger of a pancake collapse; and the fire burned unimpeded for another several hours. When the fire reached the 30th floor, it was supressed by automatic sprinklers that were being supplied by fire department pumpers. It was declared under control at 3:01 on the Feb. 24th, about 17 hours after starting. CT folks often cite this fire as an example of a serious fire in a high rise, but as one that burned longer and still did not cause the same failure as the WTC fires. The flaw in that logic is two-fold. Firstly, the fire did not burn any longer on any one floor than WTC. It simply consumed all flammable materials and moved upward. Secondly, the fire at One Meridian had only 8 floors above the damage zone, not the 20 or more at WTC. That's a significant difference in supported loads where the structural factor of safety is concerned. The photos of the damage at One Meridian show exactly what engineers would expect from such an event. The fire seriously twisted and deformed floor joists and beams, but the structure stayed up because the columns were not sufficiently damaged or displaced to cause buckling. If you're into such stuff, here's the report from the US Fire Administration: http://www.usfa.dhs.gov/downloads/pd...ons/tr-049.pdf Joe F. |
