You're a ******* idiot, sorry to say. The only 'fuel' that was burning 2 minutes after impact was whatever flammable materials were in the buildings PRIOR to impact. Most of the jet fuel was consumed in the initial impact, as witnessed by those great big fireballs you saw on the video. Whatever remained certainly didn't violate the laws of physics and 'pool up'. Also, spray on insulation is INSIDE the building and doesn't get weathered. I've worked in dozens of hi-rise buildings and have been tasked to remove said insulation in order to attach interior walls and ceilings. I KNOW what it takes to remove it.
And stop yelling or I'll add 'rude' to 'idiot'.
In April 1970, the New York City Department of Air Resources ordered contractors building the World Trade Center to stop the spraying of asbestos as an insulating material.[13]
Fireproofing was incorporated in the original construction and more was added after a fire in 1975 that spread to six floors before being extinguished. After the 1993 bombing, inspections found fireproofing to be deficient. The Port Authority was in the process of replacing it, but replacement had been completed on only 18 floors in 1 WTC, including all the floors affected by the aircraft impact and fires,[14] and on 13 floors in 2 WTC, although only three of these floors (77, 78, and 85) were directly affected by the aircraft impact.[15][note 2] and that the fireproofing was being replaced due to its asbestos content; in fact the builders had been informed of a proposed ban on using asbestos/vermiculite fireproofing during construction and had ceased using it. By this time, only the fireproofing of the lower 40 floors of the north tower had been completed, and more than half of this was later replaced before the building was completed
FiresThe light construction and hollow nature of the structures allowed the jet fuel to penetrate far inside the towers, igniting many large fires simultaneously over a wide area of the impacted floors. The fuel from the planes burned at most for a few minutes, but the contents of the buildings burned over the next hour or hour and a half.[18] It has been suggested[who?] that the fires might not have been as centrally positioned, nor as intense, had traditionally heavy high-rise construction been standing in the way of the aircraft. Debris and fuel would likely have remained mostly outside the buildings or concentrated in more peripheral areas away from the building cores, which would then not have become unique failure points. In this scenario, the towers might have stood far longer, perhaps indefinitely.[19][20] The fires were hot enough to weaken the columns and cause floors to sag, pulling perimeter columns inward and reducing their ability to support the mass of the building above.[21]

800 degrees is more then enough heat to WEAKEN STEEL TO THE POINT OF FAILURE WHEN IT'S CARRYING A LOAD.NO MATTER WHAT GRADE THE STEEL IS.
