I believe that the building had bombs on all or some of the floors. And the building exploded like when the casino's blow up an old casino in Las Vegas Nevada. Look at the same building pattern collapsing.
No one has yet to explain the presence of the residue of thermite that was found in the ash and dust left behind the collapses. This is often used to take down buildings in controlled demolition. There is ALWAYS someone crawling around in the space above the ceilings in these buildings. Plumbers, electricians, ETC. People could use this activity to place explosives. Or they COULD have been placed when the buildings were built. Might be a good idea to pull the original plans for the buildings. Those charges MIGHT be something installed at the time of construction. Why? It's a needed thing for a building to fall into its own footprint in a big city. Other buildings need to be protected. All three fell into their own footprint. Two of them had serious damage to a couple of floors, and yet they fell into their OWN FOOTPRINTS! And residue of Thermite was found for BLOCKS around. Without explanation.
True, except that the 'powers that be' keep insisting that the main towers were brought down by heat from jet fuel, (kerosene) and 7 by the fire(s). They are in a position to force feed us that blarney, and WE can't do anything about it!.
Personally, I think it's ALL a put-up job. The photos of the airplanes show at least ONE of them had NO WINDOWS. Airliners have windows. Kerosene (jet fuel) just lying around in puddles will NOT burn hot enough to damage concrete or steel. Carefully watch the beginning of the collapse of #1 and #7. You will see the radio/TV mast drop about a foot, then the building comes down. On 7, the 'penthouse' drops about a foot, and THEN the building comes down. No doubt the center support was removed, and then they collapsed.
Now we need fearless government to stop LYING about it, and we'll start getting somewhere. I'm not discounting in any way the BBC announcement of #7's collapse several minutes BEFORE it happened. It's one ting to be 'on top' of the news, it's entirely another to say it before it happens! Nor the picked up command to 'pull it'. You MUST be careful. Microphones are EVERYWHERE!
