Yes ok, baby steps:
So you do not have any reason to conclude that such fires would be unusual in a building that collapses completely with all its interior flammables still in the structure. Correct?
Then of course there is the continuing question of exactly how a long running underground fire equates to a CD having been responsible for the collapse of the structure? Where's the connect between those two thoughts Clayton?
As for the fires below various parts of the WTC complex, how exactly (please more than a two word answer Clayton) does one put out such fires especially given the fact of the numerous other examples of underground fires that have burned for years, in some cases decades, despite efforts to quench them. garbage dump, coal seam, tire pile fires all are extremely difficult to put out even with enormous amounts of water being put to them.
After you answer that you can then attempt to explain how the rubble burning for any period of time equates to a CD. This is especially important Clayton because you and others have utterly failed to make any case for this. Its not an indication of thermite as thermite is consumed very quickly. Obviously explosives are consumed even quicker (thus their designation as 'explosive') . In fact the only thing that can burn for a long time is a large quantity of carbon based material (like garbage, coal, tires, or 47 to 110 storeys worth of office building equipment and furnishings along with several storeys worth of automobile parking with its attendant diesel, gasoline, power steering, hydraulic, and brake fluids, rubber, fabrics).
So once again the query is put to you:
Exactly how does long running underground fires equate to a CD having been responsible for the collapse of the structure?
