As they say - you remove structural elements (external walls of part below, etc) so that the remaining building is like a 'house of cards' and then it is very easy to destroy it with hydraulics, etc. as seen.

So what you see is a partially dismantled structure (a 'house of cards') given a little kick so it collapses.

We French are really clever.

but you said - "under no circumstances is a crush down possible."
 
Hewia seems to imply he is aware of this method before it was posted, so when he says crush down is impossible he was lying all along.

And how is that space, the two floors that were weakened and had their exterior panels removed, Any different than an empty space of two floors Or Two Miles where you would drop the top section onto the bottom? In fact that two floor space is still filled with remaining structural components that according to you. should slow down and arrest collapse.

How come it didn't just bounce off Heiwa?

Or follow the "path of least resistance"?

LOL, the pwnage is complete in this one!
 
It doesnt matter if it was "prepared for destruction' Anders. the buildings were still standing and safe enough for workmen to install jacks to push the floor diagonally. Even in a potential wind it was safe enough to occupy. It still meets your challenge.

You are moving the goal posts. It doesnt matter if it was "prepared" or not, the top 15% or so crushed the bottom part of the building. (and nothing toppled over either even though you can see a chunk fall out the side). Bill claims this is impossible.

No, in Balzac they prepare 25% of the bottom part like a 'house of cards' so that the top 50% can drop down, etc, etc. Actually - the buildings are completely cleaned out before destruction; cables, piping, stuff to recycle are removed, etc.

says who? source that the bottom was prepared "like a house of cards". Do you even grasp that it still had to be safe enough to occupy by the workmen?

the whole building was gutted not just the bottom
and they were in it
so that building was pretty damn strong or no one would be allowed to go near it
it wasnt some "precarious house of cards" like youre trying to misrepresent here

wires and such are removed to ease cleanup and its easier to rip them out of a standing structure
also to help protect the heavy equipment
you ever see wire or other crap wrap itself around an axle or shaft and enter a seal?
i have plenty of times
(this was a problem at ground zero a lot of equipment got damaged that way)

Um, since when do cables, piping, and stuff like that factor into a buildings structural integrity??

Nothing that qualifies as structure, so why do you have a problem with that?

Because that's where all the strength comes from! You can take a 10' pipe, cut it in half, and drop the top half on the other and there will not be a global collapse! And no crush-down!
