First, in terms of the debris. I have seen close-up pics of that street, and the debris is all cladding, paper and what looks like ceiling tile. There is no significant plane debris, and surely if there was clear plane debris in that street, we would have seen a pic of it by now.Sorry, but what you think you see or don't see in a photo is certainly not evidence for the extraordinary claim you are making. I would expect that most plane pieces that didn't continue into the building (because of momentum) would pretty much look like confetti, and the fact that you haven't seen photos of any larger identifiable pieces doesn't even prove that no such photos exist, much less that no such pieces were there. If you are attempting to overturn what the rest of the world accepts as very well documented fact -- that the plane hit the building -- that ain't gonna do it.

What "violation of physics" are you claiming?
> That a solid object cannot change states in the milliseconds of a high speed impact-- it cannot initially cut into material without resistance, and then change so that the impact material offers maximal resistance, leading to disintegration of the object.Say what? Fracturing is not a change of state, and there is no need for any change of state in this case. In this case, all we're talking about is strain energy exceeding the compressive or shear strength of
both the impacting and impacted objects, so both fracture. In very high speed collisions, metal can act like a brittle material: It fractures rather than bends because local stresses build up too fast to be redistributed by deforming.
You essentially ignored my point that "the plane" was actually a compound object containing parts with different strengths: e.g. the engine cowling would be weak but the engine would contain many very strong parts; the wing skin would be weak but the wing spar would be strong; the fuel would be heavy so it has a lot of kinetic energy, and even fast-moving liquid can cut steel (e.g. the
water torch).
Since the plane was a composite object, there is no mystery that the columns destroyed
parts of the plane while other
parts of the plane destroyed the columns. But that's not the only thing going on, either: Kinetic energy is what's being converted into strain energy in a collision, so if some parts of the plane fractured before the columns did, but the fractured pieces still had momentum, then the kinetic energy in those pieces didn't just disappear. The fractured pieces can still apply strain energy to the columns when they continue plowing into them. And if the leading edges didn't do the job as they fractured, then there was plenty more kinetic energy where that came from, right behind.

What physics are you claiming that would prevent that?
> None. The issue is whether the wings and so forth would slide into the tower without significant debris being deflected, without an explosion on contact and with the plane slowing and deforming.A) The columns were 14" square on 33" centers, so most of the plane simply went through the windows. B) Fractured pieces could have deflected to either side of the columns but still had enough forward momentum to be carried into the building. C) You don't know how much plane debris was deflected, and D) you don't have any meaningful definition of "significant." E) The simple reason that the plane didn't slow down much is that the maximum force that could be transmitted to the rearward part of the plane to slow it down was exactly the force that it took to destroy the leading part as it punched through the columns, which was not much
relative to the total kinetic energy of the plane.

Furniture? Really?Yes, there was really furniture.

Also, the plane would have hit the floor slabs upon impact as well, but clearly got past those.One of the reasons I asked you to take another look at the Purdue simulation was to watch the fuselage being split lengthwise like a banana as it plowed horizontally through one of the floors.

Well, when you say the leading edge got destroyed, how much is that? 10%, 15%?I can't think of any reason why that would be remotely relevant to anything, so I won't waste time trying to estimate it. If you're trying to "fine tune" your 95% / 5% argument, maybe you missed that I don't accept that as being meaningful in any sensible way. If what you're trying to do with those numbers is inherently bogus, then the precise numbers you use are meaningless.

And you seem to say the heavier parts cut through easily but then got destroyed once inside?I'm sure you know that a (destroyed) engine and a (destroyed) landing gear made it out the other side. They were "destroyed" in the sense that they were broken and mangled, not vaporized, so I fail to see what point you are trying to make. And of course we have no idea what plane debris inside the building looked like, but it's just bizarre to claim that it couldn't have been "destroyed" if it cut through the exterior columns.
The Purdue simulation is based on
real physics, and it was done by
real physicists, Spooky. What it shows is similar enough to what we
know happened that we can have a good deal of confidence that it is reasonably accurate: Both the plane and the wall were destroyed in the collision. On the other hand, you are trying to prove an extraordinary claim that no plane even hit the building using imaginary, fuzzy-thinking physics and what you think things
ought to look like, and things you
don't see in a couple of photos. If that's the "strongest, simplest proof that the South tower plane attack was faked," then that's also the strongest, simplest proof that "no-planers" are completely out to lunch if they think they've proved anything whatsoever.
