4 Molten steel was found under the rubble of all three buildings inculding 7. here you will find at least 17 witnesses to this fact

We know it was molten steel and not molten alumium by the reddish orange colour of the material. Bottom line is that Molten steel cannot be explained by a gravity collapse from a “normal office fire”. Hence the presence of molten steel beneath tower 7 is evidence that something other than an office fire could have brought 7 down.
The fact that NIST simply deny the existence of molten steel should be a red flag for any objective minded person. Watch the lying snake oil salesman in action:

Engineers were baffled over what caused steel to evaporate. Normal office fires cannot not cause steel to melt let alone evaporate. This fact is evidence that something other than normal office fires caused structural failure of the core columns in 7.
The following s a statement from Dr. Barnett from FEMA
http://www.prisonplanet.com/engineers_are_baffled_over_the_collapse_of_7_wtc.html
For those who dont know
max temperature of a hydrocarbon fire is 825ºC (1517ºF)
melting point of typical structural steel 1510ºC (2750ºF)
temperatures required for steel to evaporate is around 2650 C (5000 F)
like molten steel debunkers must deny the existence of evaporated steel because there is NO EXPLANATION for such phenomena in the context of the offical theory.
6 Thermate reactions can melt and evaporate steel. Professor steven jones conducted tests on the dust samples at ground zero and he found iron, sulphur, potassium and manganese. The aforementioned chemicals are characteristic of a variation of thermite which is used to cut through steel very rapidly, it's called thermate.
Thermite can explain why there were molten pools of iron at the bottom of the wtc wreckages for up to 3 months. Thermite with sulphur will continue to react with iron for weeks in an oxygen starved environment and will keep it molten. Thermite contains its own supply of oxygen and does not require any external source of air. Consequently, it cannot be smothered and may ignite in any environment, given sufficient initial heat. It will burn well while wet and cannot be extinguished with water.
an underground fire fueled by normal office contents cannot explain the molten pools burning for three months.
7 Barry Jennings and Mike Hesh both experienced explosion(s) INSIDE wtc 7 on the 6th floor and lobby BEFORE any tower collasped.

www.thememoryhole.org/911/pa-transcripts/pa-police-reports01.pdf
Anyone with an objective mind after listening to the testimony of Jennings and Hesh should arrive at the conclusion that wtc 7 was a CD because they is no other rational explanation for the explosions he experienced other than “exploives.”
Summary:
(4) the existence of molten steel is denied by NIST because it cannot be explained in the context of the official story
(5) the evaporation of steel cannot be explained by the official story
(6) molten pools of steel and the evaporation of steel can be explained by thermite reactions
(7) there is no plausible explanation for the testimony of Jennings and Hesh in the context of the official story
1-7 taken cumulatively strongly support the CD hypothesis, they refute the offical hypothesis, and at the very least demand that a new independent investigation take place.
