Newton’s 3rd Law states that object B exerts an equal and opposite force on object A when A exerts a force on B. So it doesn’t matter how fast a “plane” is going when it hits a skyscraper. The result is still a completely obliterated plane outside the building. It is literally the same effect as if you put a Boeing 767 on a giant golf tee and smacked it with a steel and concrete skyscraper going hundreds of mph. Planes crumple and become disfigured even when [hitting birds](https://resources.stuff.co.nz/content/dam/images/1/l/w/5/r/n/image.related.StuffLandscapeSixteenByNine.1420x800.1lw61o.png/1506368053584.jpg) in flight. Skyscrapers like the twin towers, on the other hand, are specifically designed to withstand such trauma. Look at construction pictures and see the concrete-filled trusses and steel columns involved in their construction. This would be akin to saying that a beer can will go into a tree trunk if you shoot the can fast enough. I agree that the “how” of 9/11 isn’t nearly as important as the “who” and “why.” But it also gets tiresome seeing assertions that “no planes” is some sort of psy-op when it’s clearly the best explanation for the video we were shown. I could make the entire case here, or at least show a lot more evidence, but let’s just see what weak-ass opposition arises first.
