even if they are charges, they are not significant enough to bring down a building like that..
i was unlucky enough to watch the whole thing live on TV and as it unfolded it dawned upon me that it was likely the buildings would eventually collapse because the impact zone was far enough down the building that it would gradually allow the weight of the structure above as it degraded to far exceed the structural integrity of the whole building to the point that it could actually collapse on itself and shear downwards, tearing and degrading the existing structure below..no engineer could ever dream of such a nightmare scenario...basically demolition as a result of a strategically aimed projectile
under intense pressure & heat, like the kind that would be existent after a jet liner has basically vapourized several floors of a major high rise structure of concrete, steel, wood, plastic etc etc there will be explosions continuing after the event especially considering that the heat and pressure is temporarily contained within the glass exterior..the build up of gas and fumes from the 'relatively' confined furnace has to expand, it's just physics..the temperatures that would have been present as the plane entered and then exploded are beyond comprehension..
interesting video but i have to go with some others along the lines of spontaneous explosions resulting in random window breaks
