I consider the SAND & GRAVEL to be knowledge directly available and it raises two very big questions.
1. Where did the double volume come from? In construction/demo terms this is a huge mystery if the building was constructed as the OFFICIAL TOWER STRUCTURE shows. However, if it were constructed with a concrete core as I know it was from watching a documentary made from 16mm film shot by the architects and contractors of the towers, the volume is explained. Also the towers official design shows that the only concrete above the foundation was lightweight concrete, unless the SECOND OFFICIAL TOWER STRUCTURE ???????? is correct then an unknown type of concrete was present. Now this is a mystery. Why 2 cores? Somebody can't get their story straight? Can we notice?
What is present matches exactly what I would expect as I know the towers had concrete cores.
Then photos of remnants of the towers are not mysterious. In them are seen obvious structural elements, massive in size and strength. The character and nature of those is obvious to people having experience with the materials and techniques of construction used with them.
The OFFICIAL TOWER STRUCTURE WILL leave massive vertical columns protruding upward. The absence of those in this photo of the WTC 2 CORE after the steel has fallen away from the concrete inner tube, proves the concrete core, it shows it. It establishes quite strongly on its own that the official structure is a lie contrived to explain what was a demolition as a collapse because there are no heavy steel vertical elements pointing upwardly.
Here is a picture of the INTERIOR BOX COLUMNS which establishes what was the inner framework of the outer tube of the "tube in a tube" design. The WTC 2 CORE FALLING shows the exterior framework of the outer tube. The perimeter steel is seen as the tower top falls. The brown grey roof of the concrete core is seen inside the upside down element before falling on WTC 3.
Having accounted for all of the elements that I have so far described, there is one more structural element that is shown that the OFFICIAL TOWER STRUCTURE will not explain. The official structure has only very heavy vertical steel elements whereas the core I saw being built in the video documentary was steel reinforced cast concrete with 3" high tensile steel reinforcing bar, butt welded by specification in a series AT A SLOPING ANGLE reversing on opposite sides to create the strongest possible concrete tube.
I have just proven FEMA intentionally fabricated a deception upon the public wherin 2,800 lost their lives.
That lie shows that the SAND & GRAVEL filling the basement came from a massive concrete tower in a tower.
It is impossible to reduce that concrete to anything but big chunks by the use of high explosives UNLESS the explosive is perfectly placed and distributed. Meaning either as a sheet or a grid which is place in the center of the casting.
Where is steel reinforcing bar located in cast concrete and how is reinforcing bar distributed in concrete, what configuration is it installed with?
I've proven my point with raw evidence and no one has ever come up with a shred of the ame type evidence to contradict this scenario.
I've done the same with mind control but people are generally less informed on that subject which has a social taboo to begin with. Those most spooked by it are generally those influenced by it, they know. Even if that knowing is unconscious, they know.
Curously the knowledge of these dark areas of the past exist in our common racial histories and in the written history to a degree, meaning that the mind control via unconscious hypnosis, somnambulism, aspect is more easily accepted than the C4 coated rebar scenario creating the sand and gravel.
Most reasonable people accept quite easily that we do not know everything about the mind.
I don't talk about "why 9-11" because I know why and it is more fantastic than C4 coated rebar and has exactly the same problems with peoples ability to use existing information in simple inference with uniformity proportional to need.
The demolition is certain, by what the images show, the scenario I've defined is the only possible explanation.
Now ................. here's a mystery for you Jon.
"Why won't anyone at Let's Roll support a contest for the best over all explanation for some comprehensive scenario of 9-11?"
Planes, I generally don't talk about planes, here is why. boeing 757's and '67's are hydraulic over hydraulic controls and the pilot has a complete override. Retro fitting to remote is not at all simple or easy. Remote flights into towers mean bumble plane activity to swap out the commercial airliners. Much more chance of something going wrong. I do believe that 77 was bumbled out and a supersonic cruise missile was tested on the pentagon which is how the passengers of 77 are still alive.
Pilots do report that in simulators they could not complete the last turn of flight 175. My appraisal is that empty jetliner flights by powerful governments supporting terrorism can be used to train people to do things with airliners US pilots do not ever do.
Planes are red herrings, we don't know a lot about the flights, we can't find out about them. We depend on official accountability for everything.
With the towers, it is different.
