@TomTomBinks,
All good questions, Tom. But far afield from the science. It's a complicated event. Let's stay with the biggees which show that the official story as regards the mechanism for collapse is false. Then we can move on to other anomalies.
Focus on the molten metals. No one has ever suggested that the alleged hijackers had anything but jet fuel, which can only create temperatures of about 1,800F. Molten steel was in abundance, melting temperature about 2,750F. Vaporized steel, a much higher temperature. Molten molybdenum 4,750F.
Eutectic steel. Farmerman will field your questions on that.
Because these molten metals existed at WTC sites, we know that 19 Arabs did not cause the collapse of the three towers. Did you know there was three towers that collapsed?
As I have mentioned, Donald Trump believes that explosives must have been used in bringing down the towers. That's a given. WTCs 1 and 2 accelerated as they fell. That is impossible; it goes against the laws of physics.
WTC7 fell at free fall speed. NIST themselves, describes this free fall.
That free fall occurred from the beginning of the collapse, the first 2.25 seconds, 100 feet, 8 floors. All the thousands of tons of structural steel that had been holding up the building just as it had since its completion in 1987 was gone, in a fraction of a second, all that support was gone.
The only thing that can do that is controlled demolition. I think you'll agree, the alleged hijackers could not have set up a controlled demolition.
Let me remind you, if you haven't read it yet, the engineering professor, who is winding up a two year study of WTC7 says that the likelihood of the NIST report being accurate as to the cause of the collapse of WTC7 is ZERO.
