Why ?
Once building loses structural integrity gravity will take over and pull building down - center of building fell first, as shown by penthouse on
roof falling first before rest of structure follows it
Sunder agrees that the wreckage was tidy and explained why. "If you look at columns 79, 80 and 81 [three of the building's central columns], the floor area that they're carrying is very large—particularly column 79, which was carrying about 2000 sq. ft. of floor area." Column 79 was the first column to fail. "It was an interior column that failed, followed by two more interior columns [80 and 81], then east to west. So what you're seeing is an interior collapse, then to the outside. What you're getting is an impression of a controlled demolition, but it's not."
If was "controlled demolition" why no sounds of explosions? Hokey Smokes Bullwinkle - must have been using silent explosives!
Sunder said that his team investigated these hypothetical causes and ruled them out. "We asked ourselves what is the minimum amount of charge we could use to bring the building down," he said. "And we found that even the smallest charge would release an extremely loud sound heard half a mile away." There were no reports of such a sound; numerous observers and video recordings found the collapse to be relatively quiet.

That's a good point for consideration. Those 'meteorites' are about all I've seen to suggest any molten steel (with an actual sample that can be analyzed).
Let's say there was a tiny trickle of molten steel into the basement under WTC7 (or the other buildings for that matter) that amounted to the piddling rate of 1 litre/second average for 3 months. That would produce over 7500 cubic meters of solidified steel needing removal - anyone see that mentioned anywhere?
what was the INITIAL temp, to keep theses MOLTEN...weeks later?

Firstly, what makes you believe they were maintained in a molten state for weeks?

Which proves there were fires, if that really needs proving.
Here's a fact - steel does not melt or remain molten at that temperature in either scale.

What about the 1500 degrees Ultima1 - Fahrenheit or Celcius?
We've been over it many times and there's no evidence of temperatures measured much over 1000C which is sufficient to get steel to bright red heat just like the (unmolten) steel being held in the jaws of an excavator.

Actually , Thermite is being talked about because it was found in trace
amounts in the dust and debris.
A byproduct of Thermite is it is a quiet "burn',

You said that thermite was used cuz it's silent. That would actually make sense, and shows some rationality.
But once you include explosives in the theory, ALSO using thermite dips into irrationality.

Even tho I worked as a miner , and used explosives, I don't feel I can talk
enough about types of explosives used , for the purpose of demolition.
In mining , we used Amex and Tovex, both very loud, and we used
blasting caps.
Until 911 , I had never heard of a Cutter Charge, so what was done to bring
down a building is a grey area for me.

Do you see the irrationality of using cutter charges AND thermite?
Especially since any rational explanation of using an unproven technology in building demo - which thermite has never been used for, nor even been demonstrated to even be able to - would be unnecessarily............ stupid.
