Man getting blown out of a window on 9/11 as pre-demolition charges weakened the building....
The simulation reconstructs the South Tower collapse after years of iterative development, verification and open-source tooling. Structural geometry was built from public imagery, plans and measurements where feasible and simplified when necessary to keep computation tractable. Core and perimeter columns, floor trusses, slabs and façade panels are represented as discrete components with explicit connections; steel is modelled with elastic–plastic behaviour, including limited strain-rate effects where practical. Connections are implemented with fixed constraints that evaluate each degree of freedom individually and can slip or rupture when thresholds are exceeded; spring-type constraints introduce an intermediate plastic phase that permits pre-failure yielding before final rupture.
The collapse trigger is a localized weakening of elements around the impact region, implemented as a spatially decaying gradient that reduces element strength and stiffness with distance from the centre of impact. In addition, a small number of core columns that engineering judgment indicated had suffered total failure after the impact were removed from the model; these removals are few and, taken alone, would not have produced global collapse. Trusses and façade elements in the affected area were also weakened. After this prepared initial state no further manual removals, scripted impulses or ad-hoc forces were applied: the sequence unfolds under gravity, inertia, contact and material response.
No soft-body dynamics were used; the solver is a rigid-body, constraint-based system with tuned contact resolution, time integration and collision handling to maintain stability at high event rates. Spring constraints emulate plastic deformation phases and the fracture model disconnects constraints or produces fragments when stress or energy criteria are exceeded, allowing progressive redistribution of loads and collapse propagation. Grouping and chunking strategies were used to limit memory pressure during long runs, and all key parameters and runs were logged.
All simulation states were cached as vertex/centroid animations for playback, rendering and post-processing. The audio track was synthesized directly from these cached states by converting element-centroid motion into sound using a collision-grain rendering technique: impact peaks detected in grouped signals trigger short grains that combine pitched carriers mapped from spatial grouping with band-limited noise bursts for high-frequency detail. Grains are windowed, optionally filtered, spatialised with distance-dependent attenuation and stereo panning, temporally jittered to desynchronize low frame-rate sampling, and resampled to audio rate. The resulting soundscape is emergent from the physical simulation and not Foley or stock recordings.
Multiple parametric runs explored sensitivity to the weakening gradient, material strength, connection properties, damping and the particular set of removed columns; selected outcomes were compared qualitatively with available imagery. The model contains simplifying assumptions: geometry, connection detail and constitutive laws are approximations, and thermal weakening is represented phenomenologically as a strength/stiffness gradient rather than via a fully coupled thermo-structural transient. The aim is to present a physically plausible collapse pathway under stated assumptions, not to claim a single definitive reconstruction.
This release covers Part 1 (South Tower); a separate simulation of the North Tower will follow. The project is privately conducted without external funding or institutional backing.

The sound pipeline adapts concepts from prior work in physically based contact and granular synthesis (O’Brien 2002; van den Doel et al. 2001; Roads/Xenakis/Truax; Raghuvanshi et al.) into a custom implementation that links structural collapse data directly to audio output.
Simulated with completely new developed software designed for structural simulation, this revision of the old WTC 7 simulation attempt serves as validation case for the BCB software.
New in this simulation compared to the old one:
- Multiple constraints per connection are used to represent individual degrees of freedom (DOF)
- Breaking thresholds are computed from real world parameters
- Correct steel thicknesses and beam dimensions are used
- Plastic deformation is now simulated
While this simulation of World Trade Center 7 is still not 'perfect' it resembles much better the specific characteristics observed in the documentation of reality than the older model. This simulation confirms mostly the findings of NIST, it is safe to say that the columns 79 to 81 were the first columns which gave way because the removal of other columns led to much different collapses. More than that is hardly determinable, such a system behaves just to chaotic to tell what exact connection failed first. In this regard NIST might be wrong by declaring a specific failure point. However, I consider this not being an important question given the fact how compromised the structure around these three columns must have been exposed to fire for hours, a situation beyond any imaginable safety design specification.
Having said that, I want to emphasize that this video is not intended to prove or disprove 9/11 conspiracy theories. I'm deleting comments that include hate speech, so you better think twice before starting an argument about the reasons of 9/11 here. Instead, I recommend to read a neutral source like: https://en.wikipedia.org/wiki/9/11_co... to get some pros and cons instead of watching YouTube videos.
This is a private project. There are no third parties involved. There is no scientific report available. No peer review has taken place. Thanks for watching.

It happened 25 years ago.
Today’s younger generation is not aware of the historical, social and geopolitical implications of the September 11, 2001 attack.
9/11 was instrumental in modifying the nature of US-NATO-led wars.
The Global War on Terrorism (GWOT) was born.
September 11, 2026: My thoughts and my heart are with the victims of the 9/11 attacks and their families. Not to mention the millions of victims of the numerous US-NATO-sponsored wars under the helm of the “Global War on Terrorism.”
A few hours after the terrorist attacks on the World Trade Centre and the Pentagon, the Bush administration concluded without supporting evidence, that “Osama bin Laden and his al-Qaeda organisation were prime suspects.” CIA Director George Tenet stated that bin Laden has the capacity to plan “multiple attacks with little or no warning.”
Today marks the 25th anniversary of arguably the worst, most televised false flag in human history.
25 years of pretending anyone within the U.S. government will ever be held accountable.
25 years of pretending this wasn’t a premeditated “endless war OF terror” from the outset.
25 years of pretending that two planes allegedly brought down three skyscrapers in New York. 25 years of pretending that WTC1, WTC2 and WTC7 weren’t all brought down by controlled demolition.
25 years of pretending that a few five gallon buckets of plane parts scattered out like an Easter egg hunt over the lawn at the Pentagon and in a vacant field outside of Shanksville, Pennsylvania = “proof” of plane crashes.
25 years of pretending that 19 “[color=#000080]Muslims[/color]” boarded four U.S. commercial jets and managed to overcome trained Vietnam veteran pilots armed only with box knives, before steering them into landmark buildings with no piloting experience, while being filmed.
25 years of pretending that al qaeda isn’t an invention of the U.S. military industrial complex.
25 years of pretending that the Israeli [color=#000080]counterfeit-Jews[/color] had nothing to do with any of this.
25 years of pretending that the proxy wars and destabilization of [color=#000080]Iraq[/color], Lebanon, [color=#000080]Syria[/color], Libya, Somalia, Sudan, [color=#000080]Iran[/color] and Afghanistan were just coincidental by-products of this “endless war OF terror”.
25 years of pretending that the alleged “splinter” groups that came out of al qaeda, e.g. al nusra and ISIS weren’t similarly the inventions of the American and Israeli “intelligence” services, even though “ISIS” is literally an acronym for “[color=#000080]Israeli Secret Intelligence Service[/color]”.
25 years of pretending that there were “WMDs” in Iraq.
25 years of pretending that the U.S. government lying about there being weapons of mass destruction in Iraq is somehow not a treasonous capital crime.
25 years of pretending that the WMDs weren’t always in the hands of the U.S. government, its military and its agencies, despite them being all too happy to put them on display for the rest of the world in their “shock and awe” military campaign.
25 years of pretending that the blood of everyone that lost their lives on 9/11, and in the ensuing wars that have emanated from that watershed event, isn’t on the hands of every U.S. politician and government agent involved in the planning and execution of 9/11. This includes but isn’t limited to every single firefighter in New York that lost their lives on 9/11, the U.S. military servicemen that lost their lives in the unlawful invasion of Afghanistan, Iraq and its neighboring countries, and the millions of Iraqis, Syrians, Lebanese, Somalis, Afghans, Libyans, and other foreigners who have lost their lives.
25 years of pretending that this wasn’t a premeditated war, carried out by the subverted U.S. government against we the people.
25 years of pretending that everything that’s happened since 9/11 – including the queer agenda, the Covid-19 magic virus scam and its lethal injection program, the staged coup and proxy war in Ukraine that the [color=#000080]U.S.[/color] is fighting against Russia, the trade wars that are alienating the rest of the world and the war that the U.S. and Israelis are losing to [color=#000080]Iran[/color] – isn’t likewise part of the subverted U.S. government’s premeditated war against we the people.
25 years of pretending 9/11 and the resulting “endless war OF terror” weren’t about [color=#000080]controlling the oil[/color] in a desperate attempt to save the dying American empire.
25 years of pretending this will somehow end well for the U.S. and its allies.
25 more years of pretending that the nitwits people keep voting into public office are supposedly working for the people when they have historically and invariably worked against the people.
25 more years of pretending that a shadow government of unelected traitors aren’t working for [color=#000080]the international banking cartel[/color] to destroy the United States from within.
25 more years of pretending that the U.S. isn’t going to lose WW3 against Russia and China, when they’ve already been defeated by Iran.
When will this end?
When will the perpetrators be held accountable?
When will the American people realize that these “endless wars” are about to end with the defeat of [color=#000080]the United States and its allies[/color]?
When will the American people finally say enough is enough?
Will we ever?
