You will enjoy this. Like this jackass you will mistake wind noise for explosions... but it is a vantage point I have not seen before and thought all should see.

Here you can see the main truss failing (by fire or... explosives) and the internal structure collapsing in on itself... and then the facade basically dropping around it... which is why it looks so "demo". Which, in terms of accuracy, could have been handled with charges just as easily. But you can see how the structure fails internally, and then the shell just drops. Really wish we had some video of the base of that thing.
As for my side of the argument, the internal structure collapsing first shows that something structurally failed horribly... and while it certainly doesnt rule out demo, does show how failure of the three main web trusses which support the entire building could have caused internal collapse. Never seen a building do anything like that before.
I have another video for you that you will like too. I already see what you will see... but what I see is a key structural point in the middle being caused to fail, and the top of a building is used crush the bottom half... and then destroying itself.

People ask why I show videos that they see as furthering their cause. Because I see how they will see this, does not mean that they do, but I am not afraid of truth.
Now that is a weird demo. I don't know how they did that... and wish I spoke french... but I am looking into it.
Lastly... this is a typical demo of a WIDE building... the WTC was bigger than these... note the number of concussive explosions. Also note that it goes from the bottom down, not the top.
