That showed the how, this video gives the physics for why the twin towers collapsed. https://t.co/VpfGDCOd65

I find these World Trade Center simulations by Kostack Studio fascinating because they remove the smoke and let you see the collapse much more clearly.

In the real footage, so much is hidden by fire, dust, debris, distance, and chaos that many people come away with the impression that the towers simply dropped straight down into their own footprints.

But that is not really what happened.

These simulations make it much easier to see that the collapse begins in the heavily damaged and fire-weakened region, the upper section starts moving and tilting, and the destruction then propagates downward through the structure.

The towers do not simply disappear vertically into their own footprints. Large portions of the upper structure and exterior are moving outward and to the side as the collapse develops. Much of that motion is simply obscured in the real videos once the enormous debris cloud forms.

And this is also why I find these simulations useful when people describe the collapses as looking like “controlled demolition.”

Strip away the smoke and dust and the resemblance becomes much less convincing.

What you see is a highly asymmetric structural failure beginning around the aircraft-damaged and fire-affected floors, followed by an enormous moving mass progressively overwhelming the structure beneath it. There is tilting, rotation, exterior columns peeling away, debris being thrown far outside the building footprint, and structural failure occurring chaotically as the collapse moves downward.

That is very different from the neat mental image usually implied by “controlled demolition,” where structural supports are deliberately severed in a carefully timed sequence to produce a predetermined collapse.

And importantly, we already know what preceded these collapses.

Both towers suffered massive aircraft-impact damage. Fireproofing was stripped from portions of the structure. Large, uncontrolled fires then burned across multiple floors - for about 56 minutes in the South Tower and about 102 minutes in the North Tower - heating and weakening structural components until collapse initiated.

Once that upper mass began moving, the loads imposed on the floors and structure beneath became vastly greater than anything they had been designed to carry.

The result was progressive collapse.

No, an animation is not proof simply because it looks convincing, and these are not official NIST simulations. They are visualizations built under particular assumptions.

But as visualizations, I think they are extremely useful.

They let you see something the original footage often cannot show clearly: beneath that enormous cloud of smoke and debris was a complicated, violent, asymmetric structural failure - not two buildings neatly dropping straight down into their own footprints.

A note on the simulation: this is not intended to reproduce the collapse down to the exact motion of every beam, floor panel, and fragment of debris. No practical simulation could do that. Its value is in modeling the large-scale structural behavior - how the major sections deform, move, tilt, separate, and progressively fail. Think of it as a visualization of the mechanics and overall collapse behavior, not a frame-by-frame reconstruction of where every piece of steel ultimately landed.

This video of 9-11 in 2001 is trending in 2026 because many are saying it's the first time they've seen the video. It shows the plane hitting the second tower.

Liftoff.

The Artemis II mission launched from @NASAKennedy at 6:35pm ET (2235 UTC), propelling four astronauts on a journey around the Moon.

Artemis II will pave the way for future Moon landings, as well as the next giant leap — astronauts on Mars.

Everyone knows the NBA rookie of the year candidate within #Hornets star Kon Knueppel. Here's some highlights from his dad, Kon Knueppel Sr., who was playing in the Holy Cross Mens Open Tournament tonight.

The OG was dominating the college game in the 90's at Wisconsin Lutheran.

[WIAA State Tournaments @wiaawistate]

Wisconsin Lutheran wins their program's 3rd-straight State Title and caps off their season undefeated with a 30-0 record!🔥🏆

The Vikings also tie the State Record for Most Wins in a Season by a Team Winning a State Championship with 30 wins, congratulations Wisconsin Lutheran!😤👏 #wiaabb

19 years ago, Jason McElwain, the autistic manger for his high school basketball team, played for the first time.

In the final 4 minutes, he scored 20 points.

I’ll never forget watching this in HS & seeing him win an ESPY over Kobe’s 81-point game

This is truly the most beautiful video I’ve seen lately

So tender and heart-warming, yet it makes you stop and reflect, with a subtle touch of sadness

We may have gained so much, but perhaps we’ve lost even more✨
