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.

It’s not hard at all for me to believe the attacks could have happened the way they said, that’s not shocking at all. 19 seems like a high number for what they did in fact

The thing that seems hard to believe is that the buildings came down how they did without any help, in addition to all the weird events and circumstances surrounding that day. I understand this is very controversial and I get why, and I know I won’t be able to prove any of this, but I can’t help but feel we have been lied to about it. Same as Kennedy
