Simulation Shows How the South Tower Collapsed on 9/11

On the 25th anniversary of the September 11, 2001 terrorist attacks, a computer simulation showing the collapse of the South Tower of the World Trade Center (WTC) has once again gone viral online. The simulation by Kostack Studio shows the event without smoke, dust or debris, making it easier to follow the movement of the structure.

The footage shows the upper section of the tower beginning to tilt after being struck by the plane, before the upper floors collapse into the sections below. The absence of smoke and dust provides a clearer view of how the collapse unfolded.

The simulation has sparked numerous reactions on social media. Some see it as a clear depiction of what happened and an argument against theories of a controlled demolition, while others continue to raise questions about the collapse itself. The September 11 attacks claimed 2,996 lives.
