Above you can see the thickness of a steel perimeter column of the Twin Towers being examined at “ground zero”. Actually, it might be a little difficult to comprehend that it is impossible for an aluminum object to penetrate steel; so, exclusively for this reason here is a hint – as a basic premise. It is well-known that an armor-piercing artillery shell is made of materials stronger than the actual armor it is intended to penetrate. Typically, armor-piercing shells are made of Wolfram (Americans also produce armor-piercing shells which contain, instead of very expensive Wolfram, Uranium-238, which is an otherwise useless material, but capable of penetrating armor due to the fact that it is much heavier than steel).
Armor-piercing shells made of aluminum obviously don’t exist – this is quite obvious in of itself. Neither do aluminum swords nor any other cutting/piercing tool used to cut through steel. The mere notion that an aluminum object can slice through steel doesn’t just sound far-fetched, it sounds crazy. It shall be also noted that any armor-piercing shell fired against a tank or against any other armored object needs to travel at a speed of at least three times the speed of sound – because even though they are made of Wolfram, this aspect alone is not enough to achieve the ability to pierce steel – a very high speed is the second factor required in order to pierce steel. The speed of a typical armor-piercing shell fired from an anti-tank cannon is actually more than three times the speed of sound – it is at least 1000 meters per second and usually much faster than this, while the maximum cruise speed of a Boeing passenger jet is subsonic – meaning less than 250 m/sec even in its best scenario.
It is a good idea to look at these columns again and try and recognize the fact that their thick double walls are comparable to the armor used to make tanks. To penetrate one of these columns alone would be a challenge for even an armor-piercing shell fired from a long-barreled anti-tank cannon at point-blank range. In fact, the concept of “double-walls” is applicable only in the case of an armor-piercing shell because it faces the mere task of penetrating only two perpendicular walls that stand in its way.
However, an aluminum plane faces a much more difficult task – in addition to the two perpendicular walls standing in its way, it must also cut though two additional parallel walls because each of these tubes is actually comprised of 4 walls, not just two. And these two parallel walls, as you can see below, have a much greater “thickness” because they represent an entire 17 inch wide wall you have to slice through as well!
The picture above depicts the official diagrams showing the profiles of the peripheral columns of the Twin Towers of two types from the floors corresponding to the hits of the supposed “planes” and with arrows added by me that are illustrating the thickness of the steel being penetrated/sliced by the aluminum wings of the aircraft and of those by an armor-piercing artillery shell for comparison. The actual official diagrams of this kind can be found here:
Now, you can see how impossible it would be for the supposed armor-piercing capability of an aluminum “Boeing 767” – after seeing how difficult it is even for an artillery armor-piercing shell designed specifically for this purpose. Why then didn’t the “9/11 Commission” or the “engineers” from NIST dare not try to perform experiments in which they penetrated several steel columns with a Boeing (even a de-commissioned one)? That kind of experiment would have been ideal in proving to non-believers that it was really “terrorist planes” which managed to demolish the World Trade Center… This particular realization led many people to believe that since aluminum planes simply can’t perform such a feat, that it must have been “digital” plane which managed to cut through the dense double-walled steel perimeters of the now defunct Twin Towers…
