9/11 - WTC/Pentagon/Shanksville m.m - Tråd Nr 2

Do you think that an aluminum plane could penetrate steel thick as tank’s front armor? Try to be realistic… Yes, intuitively it might appear to some people that a massive, fast-flying aircraft, even though it is made from aluminum, has a lot of kinetic energy to penetrate steel. But this is a very wrong perception. You intuition badly cheats you in this particular case. Aluminum can not penetrate steel irrespectively of its mass and its speed. Because if it were so simple then artillery armor-piercing shells would be made from aluminum. However, anti-tank rounds are not made from it. They are made from Wolfram (Tungsten) or from Depleted Uranium. Because either of these materials is harder than steel.


Official diagram of the Twin Towers’ structure.
I will try to illustrate this to you. From the point of physics it does not matter – if a moving car A hits a stationary car B, or, vice versa – a moving car B hits a stationary car A. As long as we are talking about the speed of the moving car relative to the stationary car and the speed is the same, the physics of the process is the same. From the point of view of physics it is the same if the moving plane hits stationary Twin Tower or some fabulous giant took the Twin Tower and hits with it (as it were a huge baseball bat) a stationary plane – the physics of this process is the same. Now we move further. Let’s imagine that we have a plastic swatter to kill flies. And we hit a fly with the swatter at an impact speed of 1 meter per second. It will flatten the fly. Now we increase the speed of the swatter to 10 meters per second and hit the fly – it will again flatten the fly. We increase the speed of the swatter to 100 meters per second and hit the fly – it will again flatten the fly. And even if we increase the speed to 1000 meters per second or to any other speed, the result will be the same – the hit of the swatter will flatten the fly. I think it is very obvious. Now, we imagine that the swatter now is stationary and the fly is attempting to “penetrate” it by flying into it. If the fly hit the swatter at the speed of 1 meter per second what will happen? Apparently the fly will be flattened without being able to penetrate the plastic swatter (because it does not matter if the moving swatter hits a stationary fly or the moving fly hits a stationary swatter – the physics of this process is the same). If the fly increases the speed to 10 meters per second? The result is the same. 100 meters per second? The same. 1000 meters per second? The same: the fly will be flattened without being able to penetrate the plastic swatter irrespective of the speed of impact. The very same consideration is applicable to the aluminum planes hitting the enormously strong steel Twin Tower boasting its outer skin as strong as the front armor of a tank. An empty aluminum plane would be flattened on impact without being able to penetrate the Tower and the flattened plane will fall back to sidewalks. Add here an additional logical confirmation of what I have said. Imagine that a certain bridge collapses killing people on the bridge and under the bridge. Would you see an architect of the bridge arrested and brought before the court of law? No doubt. Have you seen an architect of the Twin Towers arrested and brought tried for his failure to provide an adequate strength to his construction? No. Now you get the point. The WTC architect is not guilty. Neither in a sense that aluminum planes could penetrate his steel building, nor in a sense that fires caused by kerosene could collapse his steel building. The architect is clearly innocent because neither of the two suggestions has taken place in reality: the aluminum planes have never penetrated the Twin Towers and “fires” did not cause the Twin Towers to collapse. Therefore there is no reason to arrest and try the architect. Do you agree with this logic?
