lol you can't prove shit, because you know shit especially for 9/11. repeating won't help you.
This is the Madrid skyscraper fire after burning 10 hours!
This the WTC after burning couple of hours:
The North Tower was hit by Flight 11 at 8:46. It collapses in 10:28 am.
1988
The First Interstate Bank Building fire in Los Angeles, which burned out of control for 3 1/2 hours and gutted 4 floors of the 64 floor tower (it did not collapse)
1991
The One Meridian Plaza fire in Philadelphia, which burned out of control for 18 hours and gutted 8 floors of the 38 floor building; (it did not collapse)
2004
The Caracas fire, which burned out of control for 17 hours in Venezuela?s
highest skyscraper, by which time all floors from the 34th to the top had been burned. (it did not collapse)
2005
The Madrid, 32-story Windsor Tower fire, which burned out of control for over 10 hours, and was not extinguished for over 24 hours. (it did not collapse)
? Molten metal was found in the subbasements of WTC sites weeks after 9/11; the melting point of structural steel is 2,750 degrees Fahrenheit and the temperature of jet fuel does not exceed 1,800 degrees. Molten metal was also found in the building known as WTC7, although no plane had struck it. Jones's paper also includes a photo of a slag of the metal being extracted from ground zero. The slag, Jones argues, could not be aluminum from the planes because in photographs the metal was salmon-toyellow-hot temperature (approximately 1,550 to 1,900 degrees F) "well above the melting temperatures of lead and aluminum," which would be a liquid at that temperature.
? Building WTC7 collapsed in 6.6 seconds, which means, Jones says, that the steel and concrete support had to be simply knocked out of the way. "Explosive demolitions are like that," he said. "It doesn't fit the model of the fire-induced pancake collapse."
? No steel-frame, high-rise buildings have ever before or since been brought down due to fires. Temperatures due to fire don't get hot enough for buildings to collapse, he says.
? Jones points to a recent article in the journal New Civil Engineering that says WTC disaster investigators at NIST (the National Institutes of Standards and Technology) "are refusing to show computer visualizations of the collapse of the Twin Towers despite calls from leading structural and fire engineers."
