@Olivier5,
Quote:Jet fuel can perfectly make a steel beam red hot. How do you think they melt iron ore if not with fossil fuels?
There wasn't any chance to concentrate the heat from the jet fuel onto any particular steel component to make it red hot. They melt iron ore, which is ground down to powders and melted in blast furnaces, a completely different thing from steel columns and beams that are massive in size and weight. Steel that is covered by fireproofing material.
Quote:Focus on the planes. They were real.
Let's allow that they were real. Let's allow that the hijackers were on the planes.
Let's allow that the hijackers brought only jet fuel and office furnishings. That can't explain the molten steel, the vaporized steel, the molten molybdenum, the nanothermite found in abundance at WTC.
The abundance, just the presence of these molten metals means that the alleged hijackers could not have caused the COLLAPSE of the WTC towers.
That WTC7 fell at free fall speed means that the alleged hijackers could not have caused the COLLAPSE of WTC7.
That WTCs 1 and 2 both fell at accelerating speed means that the alleged hijackers could not have caused the COLLAPSE of the WTC towers 1 & 2.
Free fall, accelerating speed, the symmetry of the collapses mean that the alleged hijackers could not have caused the three collapses.
Asymmetric damage causes asymmetric collapses. You can see this in the fires on the Windsor Tower, the Delphi [sp?] Building

Abstract: We have discovered distinctive red/gray chips in all the samples we have studied of the dust produced by the
destruction of the World Trade Center. Examination of four of these samples, collected from separate sites, is reported in
this paper. These red/gray chips show marked similarities in all four samples. One sample was collected by a Manhattan
resident about ten minutes after the collapse of the second WTC Tower, two the next day, and a fourth about a week later.
The properties of these chips were analyzed using optical microscopy, scanning electron microscopy (SEM), X-ray energy
dispersive spectroscopy (XEDS), and differential scanning calorimetry (DSC). The red material contains grains approximately
100 nm across which are largely iron oxide, while aluminum is contained in tiny plate-like structures. Separation
of components using methyl ethyl ketone demonstrated that elemental aluminum is present. The iron oxide and aluminum
are intimately mixed in the red material. When ignited in a DSC device the chips exhibit large but narrow exotherms occurring
at approximately 430 ˚C, far below the normal ignition temperature for conventional thermite. Numerous iron-rich
spheres are clearly observed in the residue following the ignition of these peculiar red/gray chips. The red portion of these
chips is found to be an unreacted thermitic material and highly energetic.

Point TT-6: The Claim that There Was No Molten Steel or Iron in the WTC
Point TT-6: Buildings
Introduction
According to the official account, the Twin Towers were brought down by airplane impacts and fire, and in the case of WTC 7, by fire alone. One implication of this account is that the destruction would have produced no molten steel or molten iron (which is produced in a thermite reaction). Structural steel does not begin to melt until it reaches about 1,482°C (2,700°F), and iron does not melt until it reaches 1,538°C (2,800°F). [1] The fires ignited by the plane crashes, even with the help of jet fuel, could not have been hotter than 1,000°C (1,832°F), meaning that they would have been at least 1000 degrees F. cooler than what would be necessary to melt steel/iron. The presence of molten steel or iron, therefore, would have implied that the building steel had been melted by something other than the airplane impacts and the resulting fires.
...
The evidence of molten steel or iron cannot be called “irrelevant,” given the fact that the building fires, as NIST pointed out, cannot explain it. The only explanation NIST suggested was that, if there was molten steel or iron, it would have been “due to the high temperature resulting from long exposure to combustion within the pile.” But NIST claimed that the buildings were brought down by building fires, which at most could have reached 1,000°C (1,832°F.) So the idea that burning debris from these buildings could have reached anywhere close to the temperature needed to melt structural steel (1,482°C, 2,700°F), [11] without the help of explosive or incendiary material, is implausible.
It is also unscientific.
