How can anyone have seperated this into two or three unrelated events? Now that sounds to me like complete denial of physics.
I can stack 50 tons of steel tubes and t-bars on top of a single tube or t-bar with “good weight” distribution and nothing happens.
Let’s see the video.
The video shows two towers standing firm with structural integrity and proper weight distribution throughout. Then the video shows an BIG plane (about 350 tons) hitting and penetrating the side of one of the towers, almost completely disappearing, similar to a dum dum bullet penetrating and expanding inside its target. (Moments later another BIG plane impacting the second tower in basically the same way, but at a slightly different angle)
Then the video shows an enormous fire and smoke rising from the tower at the levels of impact. Then, some few minutes later, the video shows a small buckling of the upper level of the first tower and stuff beginning to fall down from the building, more smoke. Then we see a gradual further collapsing of the upper levels and more stuff falling down, more smoke. Then some time later we see the levels just below the upper levels begin to collapse and more buckling, more stuff falling down, more smoke., etc.
All by all it took about half an hour for the building’s general integrity beginning to fail, from the top down with an an ever increasing momentum, until a total collapse was witnessed.
The whole process from impact to total collapse was close to an hour, which supports a sequential series of events. (The video also shows the second building undergoing a similar though slightly different gradual collapse).
So you think you can PROVE something with empty claims?
No, you seem to be doing that. Remember “an extraordinary claim”?
I don’t know what 3 things you are talking about. Like I said, you are the ONLY PERSON I have encountered in years trying to count the collapse from the plane impact. So you figure out how CORRECT that makes you appear.
You are the one claiming several separate and physically unrelated events (a secondary conspiracy to demolish the buildings at an opportune time), not I.
I am claiming a logically consistent sequence of events starting with the initial impact of the planes hitting the buildings and starting a domino effect.
Re your highlighted 50 ton example.
You can easily stack 50 tons on a rectangular (say) 50’ steel tube, both horizontally and vertically, as long as the total weight and balance is distributed evenly. note: a hollow rectangular tube only needs to be damaged on 1 of its four sides to lose integrity
But a 50 ton press can easily collapse or buckle the same tube, when compression weight on, and balance of the tube, is unevenly distributed.
(The crossbars (spreaders) on the main mast of a sailboat aid in keeping the mast from buckling in the middle).
http://en.wikipedia.org/wiki/Spreader, then select “spreader (sailboat)” Even then, have you seen a 2 million dollar titanium mast on ocean racers snap like a twig? It happens all the time.
I am not saying that the level at which the planes impacted the buildings was an accident. Bin Laden was familiar with structural engineering and may well have calculated some of the factors involved in bringing down a tall building.
The tube frame design using steel core and perimeter columns protected with sprayed-on fire resistant material created a relatively lightweight structure that would sway more in response to the wind compared to traditional structures such as the Empire State Building that have thick, heavy masonry for fireproofing of steel structural elements. During the design process, wind tunnel tests were done to establish design wind pressures that the World Trade Center towers could be subjected to and structural response to those forces. Experiments also were done to evaluate how much sway occupants could comfortably tolerate, however, many subjects experienced dizziness and other ill effects. One of the chief engineers Leslie Robertson worked with Canadian engineer Alan G. Davenport to develop viscoelastic dampers to absorb some of the sway. These viscoelastic dampers, used throughout the structures at the joints between floor trusses and perimeter columns along with some other structural modifications, reduced the building sway to an acceptable level.
At cost of structural integrity.
