Now, I found something pretty interesting today. Many of you are familiar with the terrorist attack on the twin towers on September 9, 2001, and many of you believe that this attack was involved with hijacked airlines. But this would be physically impossible. If you watch footage of the attack, you can see that the planes sort of melt into the building, then explode when they are inside. Newton's first law of motion states that "An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force." Looking back to the footage, you would see that the planes have no resistance against the building, and swiftly penetrates the outside of the building. Taking in the fact that the buildings are made out of double re-enforced steel walls that are ten inches thick, the plane would have penetrated the building and exploded, but not in the same way as the footage. Commercial airlines are made with aluminum, which makes these kinds of aircraft fragile. Now, if the plane were to hit a building with as much re-enforcement as the twin towers, the body would crumple up while penetrating the mass and the wings would most likely cut off of the body rather than slicing into the building. That brings up another point; Where is the debris? If you zoom in just enough, you can see there is no debris in the explosion, and that leaves us to wonder. Were planes used in the 9/11 attack on the twin towers? Upon further examination, I came upon a theory that large explosives were involved, such as nukes. Now before you say that nukes have a way too large blast radius to be used in the twin towers, the blast radius can vary. The blast radius of a nuke depends on the kiloton, usually ranging from .3 to 500 kilotons. To give some scale, a 100 megaton nuke can demolish a large city such as New York. It is possible that planes were not even involved in the attack, but rather nukes planted in different locations of the building, then detonated. I currently can't find any information that could enlighten me on why the footage was modified in the first place, so that is a mystery I can't solve at this moment. But the question remains, were planes involved in the 9/11 attack? My answer would be yes, considering the evidence. But I would like to hear your opinions, on whether you think my evidence is true, or false, that's why it's in debates after all.
