Blender Demolition - Case Study: World Trade Center (slowed down)

[@Mikinct]

Twin Towers wasn’t built like previous skyscrapers, they used trusses that are weaker than traditional buildings. It was the outer shell was where the strength was. It wasn’t that the steel completely melted, more like started the bend. You had over 15+ floors above impact level- the mere weight of those upper floors were immense. That mean a lot. That fire we’re burning for quite some time. It wasn’t like the plane hit & someone on the inside job simply pressed a big red button you get at Staples, the easy button here folks and the building cane right down. If it was staged it would’ve happened 1,2,3. Not ok, let’s all take long coffee break then come back in a few hours to press destruction button folks. Again, the entire 15 plus floors above impact zone fell as one complete unit cascading downward until it it ground level. It wasn’t like a controlled implosion where you see an explosion at top floor then see controlled explosion nowhere around top upper floors. Ask yourselves conspiracy theorists then how did the explosions now to start explosions “below” where airplane hit. Sorry but a large airplane hit not perfectly straight but slightly tilted damaging multiple floors. There’s no way that a group of inside men could know exactly what floor airplane was going to damage in order to place so-called explosives below impact zone. Conspiracy theories are just that, theories, not facts, not science. Just a feeling. They have their rights to feel what they wish. People forget that these buildings due to the massive amounts of wind generated at 104 floors up aren’t simply going to fall over like Michael Jackson did in his Smooth criminal video, ain’t gonna happen. So falling in on itself is one of the honest conclusions one would believe after the fact.

Tower 7 took massive debri hits when towers fell- I’ve seen photos of damaged integrity I building 7 then add hours upon hours of fires burning & you have it, collapses.

According to its builders & engineer, these building were designed this way to fall straight down and not topple over...straight down to ensure less damage than toppling over...thats very logical.

[@henrynevins1]

Thank you for this demo video which clearly demonstrates that the North Tower collapsed on its own due to the damage from the plane impact and the fire later weakening what structural support remained. I for one am an eye witness to the collapse of the So Tower, the first WTC tower to collapse. I worked in NYC and watched the collapse from one block away at Murray and Church streets. There were never any explosions. The So Tower the collapse began at the plane's exit hole on the bldg.'s north side which was close to a corner. That corner buckled inward and then the entire top half of the bldg. began to tilt over toward the west in a very loud cracking sound that echoed over all of downtown. You'd have to be a witness to know that because the sound is not captured on any video I have seen. As the top tilted over, the floors beneath it pancaked from the weight and top half in motion downward. The entire bldg. then disappeared into a cloud of dust and a loud rumble. Two minutes later all the electric downtown went out. I, and thousands of others on the street around WTC, didn't stick around to watch the north tower collapse 20 or so minutes later. BTW, just before the So Tower collapse, on the corner of Murray and Church street was a piece of plane engine from the plane that hit the So Tower. It was a large disc with broken turbine blades. I photographed it with my Duane Reed disposable camera. For the conspiracy bunch, missiles don't have turbine engines.

[@KaiKostack]

Thank you for taking the time sharing what you were experiencing that day.

[@henrynevins1]

Kostack Studio Your welcome. One more thing I'll add. When the So Tower fell, debris from the building fell quite a distance starting fires to nearby buildings. On Church St on a corner opposite the WTC site was a US Post Office I had been to many times. When the So Tower fell, mail trucks parked along the curb and other parked cars caught fire. I have two photos of that. Some of the conspiracy folks will say "yes there were bombs because some people still around WTC said they heard explosions." They don't know where, and that it was somewhere nearby, but then assume it had to be bombs inside the North Tower. Fact is those parked cars and trucks on fire had their gas tanks explode. I could clearly hear the sound as the So Tower collapsed, and the much fainter, but loud enough sound as the people who jumped hit the ground, but never did I hear an explosion come from WTC.

[@D13GOR]

henry nevins Your little theory here makes absolutely no sense. 1) sound isn't the only piece of evidence, smoke is seen exiting the side of the buildings in explosive fashion in multiple pieces of footage BELOW the line of collapse. 2) you are basically claiming that hundreds of cars blew up instantly as debris collided with them. Even though the explosive sounds can be heard before any debris is likely to have even come close to hitting the ground.The towers took around 10 seconds to fall. You're telling me that in well under ten seconds debris from the top fell, ignite fires with multiple cars, then blew those cars up in sync with the collapse of multiple floors of the towers? and why wasn't any explosive sounds reported to have been heard AFTER the towers came down? did all the cars suddenly decide to stop blowing up? Did they only want to do it in sync with the collapse and explosive smoke seen below the collapse line? Tell us, are you even from New York or are you just here to make shit up, I'm confused.

[@D13GOR]

henry nevins okay you're not using your brain here, let me simplify: you said that gas tanks were exploding as the building came down. In some footage of the collapse where there is sound, the sounds of explosions are in sync with the smoke leaving the building before the collapse line. So what YOU ARE IMPLYING is that the gas tanks blew up, in sync with the collapse of each floor. Even though the debris you claim to have started fires hadn't hit the floor yet, let alone had time to set fire to multiple cars and blow up their gas tanks, and YES WITHIN LESS THAT TEN SECONDS because that's how fast the towers fell. And please stop passing off uneducated guesses as some type of scientific theory. It's your word against the that of those in actual footage AT THE ACTUAL SCENE. Just because you've named a couple of streets doesn't prove you were there, I would rather believe the people at the scene, who said what they said long before inside job theories became known.

[@henrynevins1]

Diego Rodrigues Fact: My "on scene" account contradicts what you want to believe. And then I mention the pancaking building is puffing out smoke as it collapses and to you that's some kind of fk'n scientific theory? What planet are you from? Since your so stuck on the "some footage" of the collapse and explosions in sinc, then why don't you give the link to that footage? I'll watch and try to calmly evaluate it verses what I saw first hand. Even though I was on the scene, I'm willing to learn new information, if in fact the footage is believable. There's a guy among these WTC 911 videos who gives his account on the street that day. I believe he's legit because he said some things that only someone who was there, like me, would know. From his line of sight on the street, north of the So Tower, he didn't see the 2nd plane at all, only the ball of fire after impact. He then makes the baseless leap conclusion that "it had to be explosives in the bldg", yet millions of people on the ground from different angles of sight saw the damn plane. Someone like that who assumes facts, would put and innocent person in the electric chair if serving on a jury. That's why I tell only what I saw and heard first hand.

What I find interesting about this simulation is that it only shows the destruction of the top part of the towers and doesn't show how the pulverised remains of the top would continue its destructive path through an undamaged structure right to the bottom which, incidentally would be the most revealing part.

[@KaiKostack]

It's only revealing that the entire building was just too large to be simulated as a whole at the time.

[@paddy3002]

Can we expect a simulation showing how the top few floors pulverise the entire untouched bottom of the building? No one is amazed at how ten falling floors crush and pulverise the ten floors beneath them while pulverising themselves in the process. What is amazing is where the energy needed to crush the entire rest of the building came from. Can you offer any simulation help there?

[@KaiKostack]

It is planned.

[@jobapplicant8565]

Patrick Actually, the clips that hold the floor joists (actually they were trusses) had a maximum design load. Even through that load was 10 times or more what was necessary, they were not designed to hold the weight of 10 or more floors falling onto the existing floor. That weight is mass in motion, which equals energy. Once the top 15% of the building fell, the clips could not withstand the loads. The clips held for microseconds at each floor. This is what made the the falling seem controlled. The acceleration of the destruction was limited rather than at the speed of gravity (freefall speed). There would have been NOTHING revealing about the lower part of the building in this analysis. It will continue with each floor holding for microseconds and then releasing itself as the clips sheared.

[@paddy3002]

Why would you need to put bombs on all the floors? I believe these buildings had seams every three floors so all you have to do is put explosives every three floors.

Those would obviously be weak points in the building.

[@rickquinn6940]

For those with an engineering background, the World Trade Centers were the first and last of a kind of architecture called tube design. The idea is that the building is built like a tube, with the skin being the only load barring structure. In this picture, you can see the size and close distance the huge steel beams. That was the only thing holding up the building. The inside floors hung inside on the outside walls, and the vertical height also bore down on the columns. The steel beams that they used were three beams wide by two stories tall. Staggered the beams were bolted together by huge bolts, screw thread. This give allowed the building to sway 5 feet in heavy winds to dampen the energy. When the planes hit the skin, only one side needed to be breached to set off sheer collapse, each two story beam sheering the bolts. What we don't know and remains a mystery, was that they took that long to fall. The interior elevators, were only frame steel in a center column to the 78 floor. From there up hung on the outside walls. There was only two sheet's of 3/4 drywall, between the elevator core, and the floors. There was no way to get 79-110 evacuated, so they just did not sound the alarms that high. The World Trade Centers were the absolute cheapest possible way to ever build a building. It was never done after it was built. The evil Bin Laden knew of the cheap ass buildings as he tried to take out the bottom two corners in the 1993 blast. Then in 2001, he hit at the sky lobby at 78, the most vulnerable as to engineering and trapping people.

[@aSASa45454]

Was it really the last? I thought it was one of the first - and helped ignite this design to become popular. To be fair, the design was extremely efficient and did its job extraordinarily well. I think most other towers would have partially collapsed on impact. These managed to hold strong until their design ultimately led to a rapid total collapse.

Even if I agreed with everything that you said(which I don’t), I think you’ll even have to admit building 7 came down at a free fall speed for at LEAST 100 feet. I would argue it came down at free fall speed the entire time but for argument sakes, we’ll say 100 feet.There is no way that you can explain building 7’s collapse. It defies all logic UNLESS you start comparing it to other KNOWN controlled demolitions. The University of Alaska in Fairbanks spent 4 years studying the collapse of Building 7. The conclusion to their study was office fires DINNOT bring down building 7. At the end of the day, Building 7 is the smoking gun!

[@sorcerykid]

There are a lot of other factors to consider too: World Trade Center 7 was not even on the same block as the rest of the WTC complex. In fact it was located over 350 feet from ground zero. And it was the only building in all of Manhattan that was damaged by falling debris AND caught fire on multiple floors AND suffered catastrophic failure. And then there's the fact it also housed multiple federal offices, including the emergency command center for disaster management. The sheer odds of all of these factors coming together for the complete destruction of the entire World Trade Center Complex. would be like winning three Powerball lotteries in a row.

But the creators obviously love the attention so they will be the last to point that out to you. If this was a parametrically accurate simulation, then the creators would have no problem releasing all of the model specifications and values used for each metric compared to a complete inventory of all physical materials used in the construction of the WTC and their associated experimental parameter values. PLUS experimental stress/strain curves for all relevant materials, thermodynamic principles and relationships applied to the simulation, initial conditions, spatial and temporal discretization, procedure for model calibration...I think I made my point.

[@billhanna8838]

very well put ,oh did i mention the put options ?

[@MillionFoul]

As a pilot, yes, you can get a 757 to go 550 miles per hour. Most passenger planes are tested very close to mach one in a dive (including the A380, which is fuckhuge by comparison) and can sustain that speed easily, for safety reasons. You're also ignoring that as the floors fell, the were gaining both mass and speed. For every floor you fall you multiply the amount of force brought down on the floor below it by the mass of the floor, and then multiply that number times the velocity of the falling material (which is increasing) _squared_. And yes, the falling material was indeed slowed down by the floors below it, but not more than it's speed increased in the space between floors. Gravity is a bitch. "if I push real hard on some concrete, will it pulverize and eject plumes of dust everywhere? no, it will not" Yes it will. That's exactly how they figure out the strength of concrete. They use a hydraulic press to push on it, until it shatters. Also, the plane that hit the Pentagon hit with the force of .68 tons of TNT. I am of the persuasion that 1,360 lbs of dynamite would make a pretty damn big hole in a concrete air sandwich like the Pentagon. That's of course, ignoring the fuel being compressed and exploding. Lastly the hijackers were classically trained pilots who knew what they were doing very well. Pointing the nose of the aircraft wouldn't be the hard part. Navigating there would have been, and the fact that they did so clearly shows understanding of aircraft systems.

[@mkgroupuk]

I’m wondering if sky scrapers have been built different since 9/11? With stronger floors. It seems the towers actually took the impact well from the aircraft but ideally you’d expect them to stay up?

[@JackieOdonnel]

You really only need one or two floors to fall on the floor below them, and it becomes too much weight for that lower floor to handle. (It's build to hold a certain strength. And two or three floors, plus plane and debris was eventually too much weight for the couple of floors below those. So when THOSE start to fail, and they fall on the ones below THEM, it is a cascading effect called the "pancake effect." You really only need one or two floors to buckle and fall onto the floors below them, and very quickly, the next floor fails, like dominos. It's hard to wrap your head around, but if you want to understand more, do a web search on the pancake effect.

The WTC collaspe is easily demonstrated with and empty pop can and as long as it's sides remained rigid it can take a lot of pressure before being crushed. However dent the sides a little and collapsing the can can be done with less force because the load is no longer being transfered equally thru the walls. Indeed buildings like the Empire State Building transfers it load thru a forest of columns /boxes like was used in timber frame mining used in 1800 and it's why the B-25 that struct it in 1940s it caught the plane like a catchers mitt.

When WTC towers fell their debris just didn't go into its basement but came down on the entire complex including its other building. Number 7 was damaged so extensively facing away from street that it was a question of time before it to would fall. The side Building 7 shown on TV faced outward but the side that was toward the towers was almost sheared off as they fell gave the impression that it wasn't damaged at all. In Denver a number of years ago a hospital under going demolition was being picked apart from behind and collapsed unexpectedly away from the side that was still standing. Indeed the side facing City Park just of the road separating each still had its windows etc. fortunately it fell back towards the side being cut away instead across its four lanes with its traffic. It took no lives since the crew doing the destructible n were at much I believe but the hospital appeared to have been pushed over almost intact as if by a giant hand.

Well the smoke covered what it looked like but the base still stood for a bit before collapsing. Some footage you can see parts still standing then it falls. Basically the towers were very heavy

[@jnewcomb]

Two things, I was re-watching some of the live coverage from the days after the attack and one of the reports said the rubble pile for one of the towers (can't remember which) was about 5 stories high and the other tower was about 6 stories. But because both towers had a basement, a ConEd station and 6 levels of parking, A LOT of the rubble was up to 60ft+ underground. Plus the 3-4 inches of dust and debris coating all of lower Manhattan after the collapses. So not exactly vanished but certainly not as visible. Do you remember pictures of while they were clearing out the rubble, how deep that pit looked by the time they were done? 3,000 person burial site, that was, still gives me the shivers.

The towers were about 95% air, excluding the contents. So, if you were to somehow compress it within its own footprint, it would only be a few stories tall.

How would this explain the situation where the entire section of the tower above the impact zone toppled over, effectively removing the downward pressure on at least half the cross section of the standing structure. Yet the building, including the section that was trying to fall off, continued to disintegrate symmetrically...

[@AZCobraman]

It didn't topple over. it simply collapsed more toward one side (the side most heavily damaged). Once the collapse began the upper stories fell the only way they could....straight down. The towers were @ 90% empty space inside, there was nothing for the top sections to 'slide' on. Understand?

[@nigeltown6999]

I hope someone is paying to to write like that, because I really wouldn't want to think you could actually believe it. No, it didn't topple over, but it was in the process of doing that and certainly would have, were it not for the fact is was blown to pieces in mid air. Watch the videos! That section was supposed to be the 'battering ram' crushing the floors below - yet it is clearly 'disconnected' from the sections below, or it could not have moved the way it did and as far as it did, off of its alignment. And, while in the process of falling it, and the section below it are still exploding in every direction.

[@AZCobraman]

Yes Nigel, everyone who has even a basic understanding of mechanics is a paid shill.

AZCobraman Hey, thanks, no need to be so generous with your praise - but I'm surprised that you don't know about all the situations leading up to 9/11 when there were work details, out of hours activities and power outages - that could have offered people access to the building. Glad to put you right on that though. Oh and, when there is a proper, independent investigation, conducted by people who look at all the facts and what remains of the evidence - I for one will shut up if that reveals that all the coincidence, unusual happenings, first time in history events, turn out to be just plain old what jolly well happens when a hi-jacked plane that never took off is flown at an impossible speed, by people who don't know how to fly them in to buildings designed to withstand their impact...

[@AZCobraman]

C'mon man, nobody went in and tore up all the walls and cut beams and planted explosives....right where the planes hit. All that stuff is just Hollywood-style idiocy. The rest of your 'planes never took off' BS, is just as clueless as the earlier stuff. No 'independent investigation' will ever be enough for you guys. You've got it all figured out already and no amount of rational explanation, physics or evidence....not to mention live video footage of the attacks and collapses will even be enough to drag you out of your echo chambers of woo and nonsense. Oh and the towers DID withstand the impact of the planes. They remained standing long enough to allow the vast majority of the occupants to escape. And you of course know that the whole 'designed to withstand a plane hit' refers to an accident. A plane off course, going slow, low on fuel, etc. Not a plane dropping from 25K ft. going 450mph (and yes they were going that fast, it can be calculated from the videos themselves) and being flown intentionally into the buildings.

Although Newtons 3rd Law of Motion didn't happen that day it's interesting to note that in a gravitational collapse there are always body's or body parts big enough to recognize as human beings between the pancaking floors, yet on the same day that the US fighter jets decided to take the day off more than 20,000 body parts were found from 2700 victims and 1100 bodies left no fragments big enough to extract DNA from.

When it comes to the fires that softened the steel trusses, I've always found the following book excerpt interesting. "The raging fires, capable of generating their own wind systems, fed on wrecked office furniture, computers, carpets and aircraft cargo, but primarily it fed on ordinary paper - an ample supply of the white sheets that were so much a part of the larger battlefield scene. Without that paper, many experts believe, the fire might not have achieved the intensity necessary to soften and weaken the steel beyond its critical threshold. It would be simplifying things, but not by much, to conclude that it was paperwork that brought the Towers down."

[@jking4020]

Can your simulation programming show what forces made the giant sections of building fly so far away? And how most of the building materials ended up as dust at the bottom?

[@KingKehra]

Most of the building didn't end up as dust. Look at pictures of ground zero, it's mostly all metal beams. A lot of the dust that came as a result of the collapse was things like the interior masonry work (think of all the tiling), the drywall, the concrete subflooring and not to mention the entire steel structure was coated in a fireproofing compound. The large parts that were thrown off from the building is simply from the force of the top of the towers falling into the bottom, creating a lateral force on the building's exterior and essentially peeling the walls away as the mass fell through.

[@TheErockaustin]

They hauled off almost 2 millions pounds of rubble. It was a lot more than dust.

[@TheErockaustin]

The concrete however.... drop a chunk of concrete 100' and it burst into a thousand pieces. Drop thousands of tons of glass, steel and concrete from a quarter mile high and it will pulverize most of what is beneath it. Even humans were ground into dust.

[@spleenforsoul]

It's pretty crazy too if you watch when they go under the towers. A lot of it was untouched. There was a subway system and almost like a mall under the towers. After they moved a lot of the metal beams and concrete pieces they could get under there through pockets. There were news stands that still were untouched. The newspapers having that date was eerie. The stores with clothes all on the racks. Everything was covered in dust though. I was just shocked so much underneath was still okay. I watched this interview with a guy who was talking about all the cars in the underground car park they took out that were fine. I always wonder if they resold them. Someone has a car from 9/11 and has no idea. Like how they sell cars that have been in hurricanes...I think it was Katrina that people ended up getting cars from and didn't know until mold and problems from water damage started happening. As for pieces that got flung so far away. I watched this documentary and they found a guy's legs on a building pretty far away. They said it was from him sitting at his desk as the plane came in. The force and pressure literally blew things away. You can see all the debris that flies out when the plane hits. From him sitting at his desk, his legs under the desk, it protected his legs. That's why they only found the legs on that building top and not the rest. That's what it said anyway in the doc I watched.

Not to mention a very symmetrical like collapse , never seen before in history .. At the very least you would think buildings that appeared to disintegrate in this manner after those that created and bragged about their ability to withstand an airplane impact , would warrant a major MANDATORY and historical investigation, if for nothing else but to provide Architects , structural engineers, developers etc.. with much needed reform on building and safety standards to prevent something like this ever happening as much as possible .

I have studied this at great length and what nobody here seems to ask is what about Newton's third law? It states that when objects interact, they always exert equal and opposite forces on each other. Therefore, while an object is falling, if it exerts any force on objects in its path, those objects must push back, slowing the fall. If an object is observed to be in free-fall, we can conclude that nothing in the path exerts a force to slow it down, and by Newton's third law, the falling object cannot be pushing on anything else either. So in conclusion the only way for this to happen at the speed that each tower fell, including building 7 which a lot of people forget about could only happen with the help of explosives pushing away any obstacle in it's path.

[@Dan_druft]

***** That is complete fantasy, no steel framed skyscraper has ever collapsed in history like this except and only on this day, I would even go as far to say it's impossible. The towers collapsed in about 10 seconds according to the NIST report but that's pretty ridiculous because the towers were 110 storys high so for it to collapse at the said speed 10 floors a second would have to be crushed to dust ? 10 floors is about 120ft roughly which is the terminal velocity of a falling person in thin air with no obstructions 120ft per second, a building taking over a much wider area would fall slower. How the fuck can you explain that a falling building can crush an undamaged part of a building as if it wasn't there? Are we to assume the floors were made of butter ? just for an example if you were to get 4 house bricks and stand 3 on top of each other length ways then drop the 4th brick from say 1 foot what do you think will happen? will it crush through all 3 bricks turning them to powder or will it simply bounce off the top causing slight damage to the top brick. Or try standing on a packer of biscuits the more you push on it the more compressed it becomes and it will never crush all the way through unless you stamp on it. Your theory sucks

[@Dan_druft]

***** Why can't you see it's a controlled demolition ? Huge girders are being ejected out hitting other buildings including building 7 that was 370 feet away. So how is that possible without the use of explosives. There was no pancake collapse that you would expect if floors were coming down on each other floor.The whole building turned to dust. It worked 3 times on 9/11, it hasn't happened before or since 9/11 and there have been many bigger hotter longer lasting fires in other skyscrapers that didn't collapse because of fire. If skyscrapers are so vulnerable to fire why don't demolition companies simply set fire to buildings and let them collapse in to their own footprint ? Think of the money they could save. In 1975 the north tower of the wtc caught fire on the 11th floor, and spread through the corridors toward the main open office area. The fire department on arrival found a very intense fire. It was not immediately known that the fire was spreading vertically from floor to floor through openings in the floor slab. There was 125 firemen involved in fighting this fire and 28 sustained injuries from the intense heat and smoke. The fire spread to other floors and lasted for over 3 hours which is hotter and longer than what happened on 9/11 yet when the fires were extinguished the structural integrity of the building wasn't compromised at all and after being cleaned and refitted it was back to work as offices again. Popular Mechanics tried to debunk a controlled demolition on 9/11 but all they did was debunk Isaac Newton

+Dan Druft +Transparency Now You cannot reduce complex mathematical problems to simple formulas, that's why we need to do computer simulation instead of using calculators. All laws of physics worked consistently that day, if you will accept this or not.

[@Dan_druft]

+Kostack Studio You are saying that Newtons law didn't exist if we are to believe the computer simulation. It doesn’t make sense. Newtons 3rd law should also include the plane hitting the side of the building. How did a plastic and aluminium plane cut through the steel reinforced exterior grid and then manage to damage all the 47 core columns? If it was a pancake collapse then why weren’t the super strong 47 core columns still remaining, because we are told the core columns were supporting the floors so if the floors gave way why would the core columns disintegrate as well? The video simulation is nonsense as it shows a collapsing building as if it was hollow. Common sense will tell you that a smaller lighter weight falling sideways as it does in the real video clops couldn't act as a pile driver at the point of most resistance. It simply doesn’t make sense. Put Newtons 3rd Law of motion in to the computer simulation and it will drop maybe a floor then just sit there or the top will fall off. Not crush through the strongest part of the building as if it wasn't there at 10 floors a second

[@Magucci13]

Settings #1 and #7 looked the most accurate. To the people who said the core column wouldn't fail are stupid. The core column had likely been struck by the plane and had been heated and weakend. Also there was no outer structural supports for the floors, only web joists held the floors up individually. The design of the world trade center was great for wind resistance and against earthquakes, but not gravitational resistance. Each floor consisted of 3,266 tons (6 million pounds) of concrete on each floor. Each floor had over an acre of concrete 4 feet deep, let alone with all the plumbing, insulation and joists. Once one of the middle floors gave out, all that weight slamming down on each floor can cause it to collapse in no time. Most all of the people that said they planted bombs and that's how the tower fell. The witnesses stated the bombs were planted in the lower floors/basement and each of the collapses started from where the planes impacted so none of that makes any sense. It's science. Dumb people just believe those who are smarter than them, no matter how ridiculous it seems. Banscotty DP is a dipshit

[@SilverState99]

How come the building designers built it to withstand the impact of a 707, with a large margin of error, and still stand up, yet it collapsed at near free fall speed?

[@FriedrichHerschel]

A 767 is bigger/heavier then a 707. The buildings indeed withstand the impact, they didn't fell immediatly after. What didn't withstand was the fireproofing compound on the steel structure, so the fire caused by jet fuel weakened the steel so it couldn't longer support the weight of the stories on top if it. The towers didn't collapse at free fall speed kzbin.info/www/bejne/p322mY2Fq92Jm5Y at ~ 0:55

[@Jonathan_Doe_]

The fireproofing on the support beams hadn’t been adequately maintained as it wore out and started to flake off, or updated over time, because the amount of asbestos in the place meant it would’ve been a very expensive and hazardous task. Don’t start on the whole insurance job thing because I just said that though.

[@jefftormey]

FriedrichHerschel Wrong. Very little difference between the two. Fire weakened steel does not cause buildings to collapse as you can see in dozens of examples on YT. And jet fuel does not cause molten steel and was found in the basement weeks after the event. The jet fuel was burned up very quickly upon impact so you make a false assertion. The planes certainly did not cause the towers to collapse. Read Solving 9-11 by Chris Bollyn or the books by Rebecca Roth.

[@jefftormey]

Johnathan Doe So what, that does not explain molten flowing steel or catastrophic failure of all the supporting floors that were not affected by fire or impact. The planes did not cause the buildings the collapse. That is a metaphysical certitude.

[@FriedrichHerschel]

Other steel construction to collapse under fire: kzbin.info/www/bejne/an24dYumgs2ehM0&t at ~ 1:30 It didn't made a false assertion, but you just did. I said the jet fuel explosion _caused_ (as in started) the fire, not that it was the only stuff burning there. The collapse of previously undamaged floors was caused by the floors above falling onto them. There is a difference between static and dynamic load.

This is an interesting simulation. After all these years I don't know why I still view these 9/11 videos.

At this point, at least for me, it's more like a psychology study to get a glimpse into the minds of CT (conspiracy theorists) to see what makes them tick. What is causing society to be so polarized? Don't get me wrong, not all CT are uneducated morons. Many follow a pseudo scientific approach - do research and come to conclusions based on their findings. If I had the desire, I could probably do some quick internet research myself and find 'proof' that unicorns living on a flat earth do indeed exist. If you want to prove what you want to believe, the internet makes this possible. I suppose the same could be said for what I want to believe, but I've been involved in the design and failure simulations - I'm no genius, but I have some of the intellectual tools to form a realistic conclusion. Momentum, impact force, kinetic energy: it's all basic physics. On a more philosophical note, there is always Occam's razor. :)

The time is right for America to face it's past misdeeds. Believe in something...stand up for what is right!! 9/11 was an INSIDE JOB!! I'm retired USAF and worked in the Western Air Defense Sector for just over 10 years prior to 9/11. There is NO WAY that a plane could get through to the Pentagon on 9/11. First of all...the plane would be tailed by a fighter interceptor long before it reached the Pentagon! Second...the Pentagon is within Restricted Air Space. Third...all commercial planes were ordered to be grounded before the plane reached the Pentagon so at that point "shoot down" would be authorized! The plane would be shot down by the interceptor tailing it or once the plane entered Restricted Air Space...it would be shot down by a SAM since deadly force is authorized in War Readiness Status for any intrusion into Restricted Air Space! However, Cheney ordered a Stand Down allowing the plane to get through to the Pentagon. Clearly, an INSIDE JOB to defeat the US Air Defense System from within! See Norman Mineta's testimony which was extraordinary courageous during the era of Bush's Politics of Fear..."You are with us or against us!" Lastly, the FAA computer system and Air Defense computer system were fully automated. Any commercial plane that deviated from it's submitted flight plan is automatically identified by the computer system and FAA controller alerted. FAA tries to first make contact with the airline pilot if there's a deviation from flight plan or transponder is turned off. If there is an anomaly, FAA calls the Air Defense Sector and fighter interception occurs. The fighter interceptor is airborne within 5 minutes and vector is given for the interception. These are dedicated Air National Guard Air Defense fighter interceptors on 5 minute alert status on the coast. See kzbin.info/www/bejne/mHXJlYKtqZepabs

[@namordecai]

They fell at 67% free fall. Plus, the Delft building fell almost identically. Also, firefighters themselves predicted building 7 would collapse, as they saw the steel warping the sides of the building, as it expanded. After it expands, buckles and then contracts, it's so bent out of shape, it has a mere fraction of its previous power. Then, with the combination of weight, gravity and velocity, there was tremendous energy to pulverize everything. You have to consider the 2nd Law of Motion and the power of gravity. Those two explain the power of the fall.

[@fromagefrizzbizz9377]

The WTC 1 and WTC 2 collapses have some significant differences with controlled demolitions. Controlled demolitions use the minimum amount of explosive as low as possible on the building so that gravity does most of the work in breaking up the structure into manageable bits. WTC 1, 2, and 7 were 2.5 -3.5 times higher than any controlled building demolition ever, and in the case of WTC1 and WTC2, the breaks initiated above the 2/3rds point. No demolition engineer would ever do this. Requires far more demolition charges, and the chances of something going wrong are far far higher.

Excellant A+. I did much research trying to understand how they fell. The construction company Koch said in the book "Men of Steel" that if they had used a 1" bolt instead of a 5/8 bolt on the truss connections, the buildings might have stayed up. Your video helps me to finally understand how they came down with the twisting forces at play. Forget the outer walls and just picture the effect of the weight coming downing on the floor trusses and the twisting force that would be applied to the center columns. I never could understand how the tremendously strong center columns could have been brought down so easy. Your video helps understand how the twisting force may have been the reason why. Once the force is applied, it simply sheared the bolts. Amazing how it all happened so fast and nobody really ever understood it. Thanks for the video.

Did you know when metal gets hot it actually bends very easily?

[@hansdoward]

How hot can the fuel make the steel,? You do know steel is an excellent thermal conductor, so you are heating the entire structure. ANSI steel (building rated) is hardened, so more heat required. So what we are left with is a energy deficit. Not enough energy to produce the outcome. But, ignore any of that. What is really fun, because the result is impossible, is the rudder going into the building. The rudder(tail) is in no way structurally sound enough to cut through the steel outer panels. The outer panels of the world trade towers were structural steel components and what held the floor joists. So the tails of the airplanes should stay outside of the building. There is no way the physics of the situation could be any different. So if the tails of the airplanes went inside the buildings, the whole picture is a cartoon. This is the science of the rudders, and a fact no one can change. The rudders should have been broken off and stayed outside of the building. That makes the videos cartoons. And the "official story" false, without wiggle room.

What's interesting is in the 1993 WTC bombings, the bombs were detonated in at the bottom floors of the WTC... it was intended to damage the bottom completely! and the whole weight of the building should of been fighting the tension in the bottom floors, but it didn't and it didn't collapse despite the damage done... it's crazy because it just gave of the impression that the WTC were invincible. I am not a conspiracy theorist but I can see why some people would start taking a alternative belief on what happend due to its hardened past.
