I find it interesting that you have not read any of the other comments. The physics have nothing to do with a smaller item penetrating a larger item. The story of straws penetrating trees is just not true. Read the following article from a legitimate scientific publication. [livescience.com]

@gregoryL Read my link about the structure of the Twin Towers, and it makes more sense. I also read the other posts. I stand by my assertion. You want to argue it's fake, be my guest. I personally know people who were there who saw it happen live -- who were looking at the first tower wondering why it was burning, until they watched a plane slam through the second one.

There are an endless number of articles that attempt to explain how the towers collapsed, None of their explanations hold water. If you want a science based discussion based on eye witness accounts, the video recordings made that day, and the physical evidence gathered at the scene watch this video

@bleurowz I apologize, it was inappropriate to impugn your integrity.

@gregoryL Thank you. And no, I don't need to look at any videos, I know all too well what happened.

You are partially correct. The total mass is not important, but rather the distribution of the mass. The mass of the objects involved and rate at which they collide determines the energy in the collision. Here is what happens when an airplace crashes into a wooden telephone pole.

Your claim of high winds causing grass to penetrate wood is a lie. [livescience.com]

@gregoryL umm, Google it..."tornado" or "hurricane" odd effects, see pix..........actual pix, not silly conjecture....maybe you could Google "silly conjecture" as well. Also, Google basic physics, like "unstoppable force meeting immovable object" physics

Hmm. So you think it is perfectly reasonable for a hollow aluminum structure to cut through steel and concrete? ok

Agreed. There are so many flaws with This conspiracy theory you could fly a plane through it.

@gregoryL Those planes way several tons, traveling several hundred miles per hour, hitting what is a mostly glass facade. Figure it out. If I hit that with several trons of Jello at several hundred miles an hour it would go through that glass.

@Sticks48 Here is an image of the towers external steel lattice structure.

@Sticks48 Try again....[livescience.com]

@gregoryL I have been in one of those buildings. Those spaces in the frame were huge.Let it the fuck go. Get a fucking life. Leave me the fuck alone.

@Sticks48 What an expressive vocabulary you have at your disposal. You realize that just because you ignore something it doesn't go away. Do you get this angry with everything in your life that requires thought?

@gregoryL Just ignorant douchebags,like yourself. Since you are not funny or interesting you will be blocked.
