The WTC attacks were pretty unique in a lot of ways.
Usually when there’s a fire in a high rise it starts in one location on one floor, not in a catastrophic event that 1) simultaneously ignites several floors, 2) creates enough concussive force to blast the fire-resistant insulation off a bunch of structural support beams, 3) simultaneously destroys in-building fire suppression infrastructure, and 4) brings a shit-ton of highly combustible material (jet fuel) that wasn’t already in the building.
Even though Building 7 was spared the direct force of the planes’ impact, it received catastrophic damage across multiple areas of the building at once. It’s also unusual for a fire response team to have to abandon the fight to save a burning high-rise in a major city, as the FDNY was forced to do for safety reasons.
Also, the claim that no other high rise buildings have been brought down by fire damage alone is false.
