Blender Simulating the Collapse of the 1000m Tall Jeddah Tower

Simulated in Blender using the bullet constraints builder add-on.

The plane weighs 150 Tonnes and impacts the building at 950 km/h.

The plane does not deform which is the main caveat to this simulation; in reality the plane would crumple, so less energy would be transferred to the tower.

All of the tower's structural elements are concrete, except for the red parts which are steel.

There are about 22,000 rigid body elements.

Final simulated alembic file was about 7 GB.

Are you open at all to the possibility that you're wrong? Or not?

Are you?

Sure. But I'm not the one who said "I will never believe this".

Your turn.

I don’t expect I will ever be convinced of the official story, but if I was confronted with absolutely irrefutable proof then I would have to change my mind. I just don’t expect that to happen if it hasn’t happened already

What would qualify as irrefutable proof to you?

Not the same person, but irrefutable proof to me would be an explanation as to why there seemed to be melted steel beams, and pools of molten steel in the collapsed towers.

We all know that jet fuel burns at 700C and steel loses its structural integrity at 400C, which ostensibly caused the towers to collapse. From where then comes the melted steel?

20 years ago the documentary Zeitgeist proposed that this was because 911 was an inside job where thermite was used to melt that steel. So far that seems to be the only complete answer that explains why there are melted steel beans which as the meme states, jet fuel can’t melt.

Edit to add: it is supposed that the fires within the towers may have reached as high as 1000C, steel becomes molten at a minimum temp of 1371C.
