As more and more floors fail more and more of the external columns fall away, leaving guess what? The core. The reason the floor line appears to remain intact is because the massive dynamic weight is broken up and then carries on down, inside the towers, smashing the floors as it meets them. Your absurd assertion that it imploded in mid air is ridiculous and frankly the most stupid theory I have ever seen.

The collapse was nothing like two ships colliding. When two ships collide, gravity is not involved. When a massive dynamic weight falls on floors that cannot arrest it, it will continue under the pull of gravity until it meets something that can arrest it. In this case the only thing that could stop this massive weight not only falling but gaining mass as it smashed through the floor trusses was the ground.

I normally clear my ignore list now and again. You will be pleased to know you are the first back on it. Nonsense like yours is best ignored. I genuinely feel sorry for you.

End of derail , sorry folks, welcome back to ignore, Heiwa
Well, if you look carefully on the video, the roof line displaces 33 meters down during 3.17 seconds and there is no destruction taking place below floor 98! Only conclusion is that the upper part implodes.

IF there is a collision/impact it can only be between columns/floors, NOT columns/columns. You are right that the floors cannot stop the columns so the columns of the lower structure should destroy the floors of the upper part - but it does not happen! The floors of the upper part seems to have disappeared before that!

NIST has two suggestions; on the one hand the upper part is a rigid box that crushes the structure below, on the other hand the upper part is not rigid and 10 floors of the upper part drop down and overload the top floor of the lower structure. In the latter case, the columns are not affected at all.

The collapse has everything to do with two ships colliding. Two structural assemblies contact and cause local failures to each other. And the momentum, energy and force involved in the WTC1 destruction are much less than at serious ships' collisions. Regardless, you have to check where the force and momentum are applied and what failures are caused by the energy available. Evidently the upper part of WTC1 would have been seriously damaged or destroyed first, IF a collision took place. And a destroyed upper part cannot drive a collapse.

It's like bouncing a ball on a floor! If the floor destroy the ball, well, that's it! The ball does not bounce any more!

The MacQueen/Szamboti paper is excellent. It explains really what happens 3.17 seconds prior any destruction of the WTC1 below floor 93 incl. the fact that no jolt occurs = no collision of any type takes place.

You know, when ships collide, you feel it as a jolt! Same when a ship is subject to a wave impact. BANG - you feel (and hear) it. Basic physics at work.
