Super_Steve_Howey 0 Posted February 20, 2007 Share Posted February 20, 2007 There is strong evidence that Thermite may have been used to bring down the towers. http://www.whatreallyhappened.com/thermite.htm Let's be clear...Finkelstein basically purchased and insured and then re-insured (doubling the cover) a building complex which they had been unable to sell for 10 years. So he thought, what the hell, I'll just murder 3,000 people, as long as I get my money back? Link to comment Share on other sites More sharing options...

Super_Steve_Howey 0 Posted February 20, 2007 Share Posted February 20, 2007 Thermite is a reaction between aluminium and iron III oxide (present in rust, rust protection treatments and computer storage devices). A jet fueled building inferno can reach 800 deg C. Seel has a critical temperature of 500 deg C at which point it is no longer considered capable of structural support. Aluminium melts at 600 deg C. Thermite reactions occur mostly in the liquid metal phase. The normally high ignition temperature of pure thermite can be reduced by the already liquid state of aluminium, the prior presence of flame (i.e. a building fire, although thermite cannot be ignited by flame alone), and the presence of small quantities of sulphur (a by-product of innefficient hydrocarbon burning i.e. a building fire). Thermite reactions can be initiated by high energy friction of metals and abrasives (i.e. a building collapsing). Once ignited, a thermite reaction requires no oxygen (i.e. it cannot be smothered) and will sustain itself from iron oxide and reactive metals (aluminium, copper, steel i.e. a building debris field). Thermite reactions produce extremely high temperatures (i.e. capable of melting steel), exacerbated by the inability of the reaction heat to escape (i.e. in an underground fire).

Guest alex Posted February 20, 2007 Share Posted February 20, 2007 I've never heard anyone use alloy as a term to mean aluminium tbh. Is it commonly used in cycling? Aluminium is an element/metal. I've only ever known alloy to be used to describe a mixture of metals/elements. [/basic GCSE] Link to comment Share on other sites More sharing options...

To put it politely they have some issues with the way the buildings were re-insured.....And Finkelstien isn't one of their favourite people...The way this kind of insurance works is that the risk is often diluted by seperate entities taking up the cover as a joint venture. Without going into detail Lloyds were highly circumspect about the re-insurance package and the formula involved. We're not quite in the territory of renegade brokers....But we're close.

Steel is just the element iron that has been processed to control the amount of carbon. Iron, out of the ground, melts at around 1510 degrees C (2750°F). Steel often melts at around 1370 degrees C (2500°F). Steel doesn't need to melt to bacome structurally unsound. You can bend steel without metling it right? The figure is for standard structural steel. Steel alloys contains trace amounts of other elements/compunds (not metals) to engender enhanced properties. This is not to increase melting point, since the material is still 99% Fe. Using complicated alloys is not cost-effective or even necessary for structural support, structural design is far more important, standard properly hardened steel is sufficient for buildings given the above. Plus these towers date from the 60's no?. I know what you're saying, but how does a fire on a few floors near the top of such a building make the steel fail near the bottom? Built in the late 70's iirc. Lloyds of London were left holding the main risk mamagement. One or two of whom are clients of mine as they are also heavily involved in shipping. You should hear what they say after a few beers. Who says it did? You should hear what they say after a few beers What did they say? To put it politely they have some issues with the way the buildings were re-insured.....And Finkelstien isn't one of their favourite people...The way this kind of insurance works is that the risk is often diluted by seperate entities taking up the cover as a joint venture. Without going into detail Lloyds were highly circumspect about the re-insurance package and the formula involved. We're not quite in the territory of renegade brokers....But we're close. Spell it out for me, i'm ignorant in felony insurance fraud. Aren't they just sore they had to pay out an insurance policy, or is there something else I've missed?

Guest alex Posted February 20, 2007 Share Posted February 20, 2007 Can these supposed irregularities about the insurance be sourced anywhere other than conspiracy sites/message board hearsay though? Because I would have expected the media to have picked up on it but I've only ever heard about it on here or N-O. Link to comment Share on other sites More sharing options...
Kevin Carr's Gloves 4087 Posted February 20, 2007 Share Posted February 20, 2007 The one conspiracy theory about the whole thing is the Pentagon hit. Never seen a plane leave such a neat whole and no wreckage before. Link to comment Share on other sites More sharing options...
