Building 7 was on fire over ten hours because the focus was on rescue attempts in the collapsed towers and the already huge loss and strain on missing firefighters.
No, it was not. Portions, and that is the operative word, PORTIONS, of WTC7 were on fire for slightly less than 7 hours. That is how office fires go. As the fuel is used up the fire moves to a new area of fuel. The short time duration of offices fires has no chance to heat up structural steel enough to cause failure, let alone a symmetrical, free fall collapse.
That is 100% impossible.
It also wasn't standard construction. I posted an animation that shows how it collapsed internally before you really saw the shell of the building fall. The reason it fell so fast was due to the internal structure was already hallowed out from collapse.
Please post your animation again. It has to be the NIST animation.
Point 1: Since the NIST study was a fraud, it follows that their animation was a fraud.
Point 2: It is completely impossible, that is a zero chance that the "internal structure was already hallowed out from collapse". The internal structure is part and parcel of the entire structure. They are all tied together.
What do you think half of all the floors and floor loads are supported by?
An internal collapse, if it could ever happen on its own, it cannot, would cause huge deformations in the external structural steel.
I'm skeptical of any engineer who looks at molten metal and identify its type. It easily could have been mistaken for molten aluminum which melting point I'd just a few hundred degrees.
Nope. Molten aluminum appears silvery in daylight conditions. The yellow/white color of the molten steel/iron falling from WTC2 minutes before it was blown up, shows the metal was iron/steel.
Not only that but when you have steel coated with hot aluminum it severely weakens the steel. It doesn't even need to melt to cause failure of the material under load.
The steel wasn't coated with hot aluminum. The material found on the eutectic steel from both the twin towers and 7 was caused by sulfidation. That means thermate which has sulfur added to cause the steel's melting point to be much reduced.
The following explains it all.
