Did you look into the study made by the university of Alaska to begin with?
This is 100% bs, shame on you in a nice but bad try misleading the population. Said by a guy with a top Mensa IQ and Sir Isaac Newton agrees.
Looking forward to this as so many people use WTC 7 as "proof" of a conspiracy. I don't get it personally as a collapse of two 110 story buildings would compromise the structure of buildings near by from the vibrations alone and that's ignoring falling debris and fire.
I'd suggest everyone to unsubscribe until he looks at the study made by the University of Alaska. It seems like the guy behind Lesics has become desperate for clicks.
FAIL ... it was NOT an actual university study BY the university ... but instead a PRIVATE COMMISSION by the morons of Richard Gages wee fourteen year old online pretend petition that PAID an ALREADY believe to find what he was PAID to find.@@ziad_jkhan
I did not expect a video on 9/11 to have a 3d Hulk within its first 30 seconds
Haven't watched the video yet i wonder what's the context of why a hulk is represented in a 9/11 video

Please do a video of the physics of the Building 7 collapse on the same day. the building that was NOT hit by any plane, and was newer, with better engineering.

You sound open minded
All those buildings were controlled Demolitions ! Done by you know who !

If you can acknowledge that trivializing one of the most important events in history is at best naive, that would be good for you. Do some research. Start with terms like building 7, thermite, Larry Silverstein, and NORAD.

@@jpeterson1488 yes.
As a scientist, architect, demolition specialist, engineer, car dealer, actuary, and a Uber driver I can confirm this is not true
So crazy... the videos of the towers falling AT FREE FALL RATE, building 7, prove that were brought down with controlled explosions yet people just blindly believe what their told. Even the builders of the towers even said the buildings were designed to withstand 100 planes flying into them - what a world we live in...

Very informative. Any chance you could do a video that explains how WTC building 7 collapsed in the exact same way (despite not getting hit by a plane)?
Well stated and on point. Ppl still believe it was the planes, and according to majority of the know it alls I seen, was that supposedly a part of one of the towers fell onto building seven (even this CGI shows how the towers fell). It does not add up at all.
Debris from the WTC1 and WTC2 collapses damaged the buildings around them, including WTC7, and started major fires which were left to burn for seven hours. The heat weakened internal core steel columns in one part of the building failed vertically. And then the now unsupported adjacent columns failed laterally. The debris from the steel frame collapsing pierced the now freestanding outer shell near the base and it finally collapsed.
😂👏
ALL the columns in bldg 7 collapsed at the same time, not just the few which were hot from a fire. The columns which fireman were standing right next to just 5 minutes earlier were not surrounded by flames.
@@martoto77 LMAO🤣🤣🤣
What always impresses me most are the people trapped in the tower. Nothing and no one, not technology, not money, not the army could save them from death. It felt like the end of times.

@@dikranovichk5889DIGGLER PLEASE ‼️‼️‼️
I can't believe a video with Hulk executing the Trade Center is the only video in 22 years to explain this in a way that seems logical. The question was always: if the floors pancaked, where was the steel core? The sagging floor demonstrating pulling the walls inwards makes a LOT of sense.
The planes engines blew through the towers. Heavy components took out or distorted many core columns, the others descended by being dragged down by the external walls _through_ the top hat truss. It was my first thought too - but I am an engineer . . . and thought again.
I did not expect that Gmod💩! 😏
Certainly “seems” logical. Yet the inconvenient truth remains. Never forget even the experienced news casters that day said the phrase “controlled demoIition”
The steel core remained for a few minutes before also giving out, likely from joints no longer being within tolerance and also falling like a house of cards. You can see it happen in real time with the NBC coverage of the collapse. Once the smoke clears a little bit, you can clearly see the cores failure.
@@CoercedJab what a difference the words *_like a_* make when omitted . . . 😎
I worked at 2 WTC up until April 2001. I got laid off from a start up. I was amazed at those buildings. I would stare straight up on my lunch break in amazement. I guess it wasn’t my time. RIP to all who perished.
My dad worked across the street delivering to WTC1 and WTC2 frequently, he quit 6 months before the towers collapsed. I was 5
Having survived 9/11 only because of a layoff… wow, I would imagine that was probably life-changing for you! I never worked in the towers but whenever I was on foot in the city, I would stop to look up at the tops of them. Even from a block away, I would have to bend my neck and arch my back to the point that it felt as if I were looking up at something BEHIND me in the sky!
How do you know somebody worked in the WTC buildings?
Don’t worry they’ll tell you.
Unless, you know.
@TheNJDirector I don't know you but I'm glad to be able to read your comment. Thank God you made it. Go have a amazing year(s).
Very informative and easy to understand. Thanks for also providing the demonstration with the coke can.
Did anyone else get that sickening feeling in their stomach by just imagining being a builder of such buildings? The way they show those animated men standing on ladders so close to open floors, or just imagining being the operator of a "Kangaroo Crane" truly makes me almost sick. I feel the same way watching bridge workers, or just imagining the work that goes into building such bridges! It take a SPECIAL type of person to be willing and able to do such things!
I get a sickening feeling when I see three videos . The first Is of the towers exploding into dust as they fall from the sky . The second and most revolting Is Larry Silverstein confessing to his part in ordering the demolitions . Lastly this video and it’s farcical attempt to change what we all saw on 9/11
It also takes a "special" kind of person to destroy such things.
@@jkm1611 Larry Silverstein confessed to it. He wasn’t that special , sociopathic maybe
As somebody who works in construction,
You get used to it pretty quick, also we follow monumentally detailed safety programs.
As long as you're practicing basic situational awareness you'll be fine.
Balls. It takes people with balls. The female workers have to have balls too.
I was taking engineering when this happened. My structural engineering professor was very confused about how the towers collapsed. He said that it didn't make sense. They shouldn't have fallen; let alone a total collapse.
Thats because he was not contacted/funded by the feds so he was free to use his brain.
Really? Apparently your professor never heard of progressive collapse or maybe he made his misinformed comments before seeing videos that clearly show the floors pancaking into the basement.
@@marcpowell5893 Watch the actual video. The building collapses from the bottom, not the top. The top of the building in intact until it hits the ground. debunking the pancake theory.
@@marcpowell5893 And the buildings were designed to withstand an impact of an airliner.
@@scottcraig2569 The graphics in this video are flakey but the theory it mentions is fairly accurate. After collapse initiation, the connections of the floors to the columns progressively failed resulting in the floors pancaking. That is what caused the sequential dust and debris ejections from windows seen in multiple videos. Claims by designers that the buildings could withstand aircraft impacts without severe damage were merely engineering hubris. The buildings obviously could not.
And building 7 was so scared seeing these two towers fall that it just gave up and collapsed inward on itself. Quite remarkable
Fire will do that…
@@catfishcave379No it won’t.
@@johnbruce4003 So Sorry, it was Col Mustard in the conservatory with building demolition caps. I was stupid to believe all the footage of the roaring fires and several partial collapses. When facts get in the way - go conspiracy!
@@catfishcave379fire makes controlled free fall demolition? No need for explosions then?
@@pse2020 Bingo! Spot on... fire can't create a free fall collapse of that building. To those who doubt: then why did the construction crane NOT melt, that was closer to the Towers than Bldg 7? Yet B7 collapses?? We need an explanation that includes the obvious use of demolitions. You are spot on.

I hope the collapse of te towers didnt collapse your heart. R.I.P.
You explain why the floors fail where the planes crashed into, but what about the 100 or 150 feet of intact building below the crashed part
The video does, but not very well since it is both obvious and not that important. Pay special attention at #10.
1. Plane hits building causing massive structural damage. The plane is completely destroyed in a fraction of a second, but this in no way implies no damage to the building. Large fires break out across multiple floors simultaneously with no fire fighting or fire suppression in an unprecedented fire event.
2. What happens to steel when you heat it? The steel gets softer. The longer you heat it and the hotter it gets the steel starts to _bend_
3. Bent steel is not as strong as straight steel.
4. The steel floor trusses start to bend (sag) from the heat and the weight of the concrete floors, furniture and equipment.
5. Sagging floor trusses pull some of the surviving perimeter (outside) columns inward, causing them to bow by up to five feet.
6. Bent steel is not as strong as straight steel.
7. The perimeter columns bend until they buckle (best seen in the Gary Pollard video of the South Tower collapse linked in the description above).
8. Columns - which carry ALL of the gravity loads - above and below the failure point are *no longer aligned*
9. The falling upper mass drops _past the columns_ below, NOT onto them. THIS BIT IS IMPORTANT!!!
10. Tens of thousands of tons of debris falls _down_ through the open office space *within the four outer walls* . As that debris hits the next floor, that floor fails when the pair of bolts connecting each truss to the core and perimeter columns shear off. The debris then falls the next 12 feet with the mass of the newly failed floor added to it and hits the next floor, which fails. Rinse and repeat x90. This proceeds through all the floors one by one until the floors are all gone.
11. Rate of collapse increases as the collapse progresses. The collapse accelerates from zero, slows only very slightly with the first impact, speeds up again (this time not from a starting point of zero) and as the momentum and mass increases, the slow down with each impact decreases. There was exactly as much resistance as there should have been. _average_ rate of collapse for this stage was 0.65 of GA.
12. The perimeter columns, no longer attached to the rest of the building and thus lacking critical lateral support fall away - peel.
13. The central core columns, damaged by the falling debris and with no lateral support from the perimeter columns fall last.
14. The Twin Towers were an integrated structure. None of the three major components - core system, perimeter columns and long-span floor truss systems - could survive without the others.
Yea... he also conveniently left out the fact both buildings had 2 reinforcement sections that were there specifically for this purpose. Look at pictures when the towers were standing and you can see where they were
He does at 9:58 he said the floors above the damaged area weighed as much as the titanic. The only problem is in the animation after it looks like the building is collapsing from ground level when in reality it collapsed from the top down.
Now I can better understand what really happened. I'm no engineer but I can understand why the collapse happened due to unforeseen build designs, and how much a weak floor support can matter in such a situation, as well as how much fire insulation can do too.

To my knowledge the spray foam mentioned was actually asbestos based and came in huge quantities, causing long lasting health risks to people close to the building after the collapse.
Absolutely true, so there will be more death people in the near future linked with this disaster than actually on paper
Most of the fire retardant spray on material is asbestos material. I’m not sure if it’s still in use today but it’s literally everywhere and not just spray foam insulation but loads of other materials as well.
Yup, they were told they had to update the buildings prior to 9/11.
The cost was estimated at morethan the two towers' value.
The owner made around 4 billion in insurance when they fell as well.
You are incorrect. Only the North Tower had any asbestos in it at all and only below the 40th floor. The SFRM used in the rest of the North Tower and ALL of the South Tower contained no asbestos material. Plenty of toxins floating around that site. Why people have to just jump to assumptions about asbestos and ignore true and relevant facts boggles my mind.
The construction companies that built the towers was owned by the Italian mafia they pocketed the money that the building developers gave to them and brought CHEAP METAL NOT STEAL !!!!….
in my 91 years of being a structural architect engineer in college, i can confidently state that the use of the metal pipe sound effect was hilarious

What? 91 years of being a structural engineer in college? You’re like 110 and never graduated?
See people, _that_ is how you troll.
how much did the tower weigh and the jet.. concrete. how can an alluminum balloon jet destroy iron steel and concrete the heat energy from the jet fuel can be measured in the external fireball image. that fact then determines the heat energy within the building u explain that the material within the building was fuel to expand the fire damage melting at some point all the heat energy was absorbed from then un burned frame.. same effect at the pentagon why no destruction there? next time your got nothing to do look at an image of the pentagon and a ukraiin missel striking a building.. the lies shankswberg pa no piece of anything look at images of plane crashes there is stuff everywhere no cameras laughable

@@lurch789I’d rather have to Bush’s than the tard we have now
It was assumed until that day that when terrorists hijack a plane, they do it to use the passengers as bargaining leverage - they want something and will trade passengers to get it. That is why the standard procedure for passengers was to not try to fight the hijackers: you are worth more to the hijacker alive than dead, unless you start to cause problems for them. So what was not imagined was terrorists hijacking a plane not to get the passengers but to get the plane itself. This is why the 9/11 terrorists chose flights that typically had low passenger volumes.
As soon as the passengers on United Flight 93 found out that they were not being taken hostage, but that the terrorists were going to kill everyone, the calculus changed and they heroically fought back. They gave their lives to save those at whatever the fourth target was. We all know now that if we are on a plane that someone tries to hijack, we all get out of our seats and overwhelm the hijackers with superior numbers.
@@Murph_gaming They defiantly had terrorism concerns at the time of construction. That still doesn't mean they thought it would happen.

However, I am keenly interested in the physics of the "why" of the collapse of Tower 7...
and why the boss had an appointment at that day and why was there a new ensurance for a asbestos soaked building?
See, this is what totally made me realize that it was planned. You're telling me, a giant skyscraper, which burned for about 7 hours, just collapses? There wasn't even smoke or anything like that billowing out, and the skyscraper that caught fire in Hong Kong, didn't collapse despite it burning for 9 hours, and it was a lot less wider than WTC 7, which other buildings around did catch some fire, but were okay. Can't make this nonsense up, two trillion dissapeared on the same day as well? Yeah, what a conspiracy, the government would never do anything wrong to the people.

Man I didn’t know jet fuel burned that hot. How did building 7 collapse the same way as the twin towers without a plane hitting it?
Shhhhhh.... you'll wake the sheep.
Because two entire towers fell onto it? And the jet fuel didn't melt the beams, but the beams still became more malleable by the heat. Metal doesn't just instantly transform from cold to melted, it slowly weakens. The beams got hot and became easier to bend, which allowed the weight of the building and the plane to put enough pressure on them for them to snap.
Bingo! I bet you he doesn't have an answer.
Anybody who passed grade school physics classes has the answer.@@rickyt11
It was loaded with backup diesel generators. Once WTC 7 was hit by the collapse, a fire started and spread to the fuel storages.
The animation at 10:15 is very unfortunate, as the entire structure moves down at the same time. This movement would only occur if the tower collapses from the bottom (nutjob theory of bombs on bottom floor) rather than from the top (what actually happenend: plane crash). I understand it is done to make the animation a little easier to produce, but it's important to note that , when looking at videos of the collapse, the towers clearly collapse from the top, and not the bottom.
My observations as well.
Yeah.. It's hard to animate the steel core failing for no reason. :)
Lets just sink it all into the ground.. nailed it
This is completely inaccurate. This video is actively engaging in the Terr orism.
Exactly, none of the animations match reality.
Naysayers refuse to acknowledge that fact the the interior of the structure was moving and collapsing at a different rate than the exterior exoskeleton. Because of this oversight, conspiracy theories abound by feeble and shallow minds and will continue to do so in perpetuity.
Thanks!
Please make a video on the Chernobyl main building collapse due to nuclear explosion.
The only problem I have with the animation in this video is that the animator rendered the video so that it made it appear as though the building was collapsing at ground level, whereas in reality, the collapse occurred right below the damage area in the building. The floors were collapsing in a pancake fashion starting below the fires and continuing on down.
I noticed that too. Very strange.

@@feralzi8930 did you watch the video
It looks like they didnt actually animate a collapse they just made the model move down and have ruble move upwards from the ground
@@vuurkip2491 i did watch the video but but you know what's very strange is that the towers were engineered so that it can withstand a 707 crash. You think fuel from 707 coming from the middle east will have a tank full of fuel? Most of the fire exits through the hole the plane makes and some of the fuel can spill out. So it's dumb and illogical to say that just plane fuel can collapse a building after 1 hour of the towers withstanding it. There is definitely external interference occuring that cause the building to basically freefall
Great animation, forgot to mention the guy shown spraying the "insulation foam" was spraying Asbestos insulation, each tower contained approximately 300 ton of Asbestos, which was turned to dust when the towers fell dispersing Asbestos dust all over the city, the affects of this started to show in 2019 with cases of Mesothelioma rising, As of December 2020, 80,146 first responders enrolled in the WTC Health program to receive treatment for 9/11-related illness, sadly there will be hundreds of thousands of citizens who will also require treatment.
Know that the whole tower turned to dust. Not only the asbestos.
Why were the towers dustified on the way down instead of instead of in giant floor sections and walls like a normal pancaking collapse? Why did everyone in the lobby and basement report bombs having gone off prior to the planes hitting?
@@Turdfergusen382 Yeah, especially the core, just one tube standing there? ...
There were 100,000 tons of steel in each tower. Even without the insulation how hot could the core columns get in two hours?
Where is the data on the tons of steel and tons of concrete on each level? Including the 6 basement levels.
@@psikeyhackr6914 Well I’m not sure how…. But somehow hot enough to be molten metal in a pile at the bottom for three months after even though they were spraying water on it constantly….
Firefighters have a saying "Never trust the truss" light strong until they are not and then failure is immediate. The more terrifying part of this video is the foam protects for an hour, but the people in the buildings all said that even in drills it took several hours to go from the higher floors to the bottom
Interesting observation: It took hours for people to move between the same locations that took seconds for some inert object to move through itself, even though the force created by an accelerated mass is only applicable between locations (MxA=F); because the path of greatest resistance is always through oneself, whether it's as poorly constructed as a pillar of cigarette ash or as strongly constructed as a wrecking ball.

While I do not deny any allegations addressed to the U.S. government or accusations about different aspects of 911 not making sense, after watching this video, the speed at which the buildings fell apart is more understandable to me.
It, of course, does not justify the architects' neglect of implementing proper security measures before finalizing the building of the World Trade Center; an understanding of how the buildings were made in the first place gives a lot of insight.
This isn't to say that there could not have been other causes or contributing factors of the attack and explosion; however, I lean toward believing that the building was not in a proper shape to sustain an attack by such a size plane in the first place.

Yet the engineer stated it wouldn’t collapse from an airplane. Specifically designed to handle a 747
That's impressive, considering there was no such thing as a 747 when the towers were built.
Not to mention, of course, that no-one has ever, before or after, "specifically designed" for anything of the sort.
No it was not designed to handle a 747. How do you even design a skyscraper to "handle a 747"??? Why do you twoofers lie constantly?
How do the architects and engineers involved in the design and construction of the twin towers feel about this explanation. I just find the speed of the collapse downwards, without any resistance from the concrete reinforced constructs giving any pause for the collapse, astonishing.
the dancing israelis didn't find it surprising
Minoru Yamasaki was the architect of wtc, and he was notorious for designing buildings with catastrophic flaws.
The Towers were NOT concrete reinforced.
Again, one of you "truthers" fails in their premise, therefore making any conclusion laughably false.
*World trade center towers did not have any reinforced concrete.* They were made of steel plate boxes (down to quarter inch thin at upper floors) and I-beams, all sprayed with loosely adhering fire retardant foam. Upper floors had original, asbestos based, crumbly foam.
Scenario where heavy airplanes at full speed hit the buildings and initiate a sudden multistorey fire fueled by office combustibles was WAY BEYOND THE SAFETY DESIGN LIMITS and the fact they stood for so long goes to show how well they were designed. Contrary to this video's false idea, any other classical steel building with evenly spaced columns would fall very fast or almost immediately from the impact alone.

FAKE PLANT ALERT ‼️
The Boeing 787 didn't enter service until 2011, the planes that hit the towers were 767s.
Indeed so. Another consideration is that the 767 is very similar in both size and weight to the largest of the Boeing 707's - the intercontinental version. In fact, at the fuel loads of the two airplanes that hit the WTC, their weight would have been around the same as, or a bit less than, that of a fully loaded 707. Although the 767 is a twin aisle airplane, and thus has a slightly wider fuselage, it is fairly close to the overall size of the 707 dimensionally. So the testing done during the development of the WTC was not as far off the mark as many may think.

By the way, another building collapsed nearby at the same time, into which the plane did not crash, and it also collapsed according to the same pattern...
Yes it did, due to severe structural damage from being hit by the North Tower collapse, whose penetrating flaming debris started fires in World Trade Center 7, fires which NYFD realized they could not control, and would not control due to fear of the building possibly being mortally damaged. Fire weakened the steel in WTC7 just as it did in the twin towers.

@@bobbyd6040 - The Titanic was supposed to be unsinkable and the Twin Towers should withstand the _impact_ of a commercial jet (whatever that means). Are you baffled when grazing an iceberg sank the Titanic as you are with the Twin Towers collapsing after being hit by a plane each?
For the record: *The Twin Towers were never **_designed_** to withstand any sort of aircraft impact, however one may choose to define that* (and there are many ways to define what that actually means). This was not a requirement of the customer or of NYC building code and you will see no mention of it in the building plans.
What is true (apparently) is the _accidental_ impact of a jet lost in fog while on landing approach (light and slow) was studied at a crude level in a 3-page memo of hand-worked calculations. What was NOT studied was what happened on 9/11/2001 the intentional high-speed Kamikaze attack by a much larger aircraft moving at full tilt. This crude study was performed AFTER primary design work on the Twin Towers had been was completed (after the time for any major changes was past), with the precedent being an _accidental flight collision_ along the lines of the July 1945 Empire State Building crash. The scenario studied was a narrow-body Boeing 707 (then the largest aircraft in service) on landing approach (light and slow - about 200 mph and low fuel load) lost in fog. This study did NOT consider the 9/11 scenario of a larger, heavier and high fuel load wide-body passenger jet being intentionally accelerated to maximum speed in a kamikaze attack.
Those are two very different animals. The calculations and methodologies used in the original airplane impact analysis circa about 1964 have not been found. We have only anecdotal accounts that they were done and what they concluded. So exactly what impact dynamics and damage the Twin Towers were expected to withstand can not be determined. However, given the rudimentary nature of modeling capabilities in the 1960’s (calculations done by hand with pencil and slide rule, not 3D computer graphics and AI), it is doubtful that the analysis would have been conclusive and, at any rate, it did not include the effects of _the resultant fires which are what ultimately brought down the Towers_ . Such effects are exceptionally difficult, expensive and time consuming to model even today and at any rate, given the 1964 scenario would not have informed us much about the very different circumstances of 9/11/2001.
As Leslie Robertson, the lead engineer on the Twin Towers building project said after 9/11: _To the best of our knowledge, little was known about the effects of a fire from such an aircraft, and no designs were prepared for that circumstance. Indeed, at that time, no fireproofing systems were available to control the effects of such fires_ . For some reason *this part is always ignored by conspiracists* They bang on about “designed for impact”, forgetting to note they were not designed for the subsequent multi-floor fires. And there is the rub. Collapse of the Twin Towers was due to just one factor (physical damage from aircraft impact) but to four (4) factors, of which commenters all too commonly only consider one, maybe two, but _never_ all four.
Impact Damage does not = collapse. Both Towers survived the _impacts_ obviously.
Fire does not even = collapse. Not by itself.
It was a combo platter; *Impact Damage + Fire (heat) + Time + Gravity = Collapse*
Remove any one (1) of those four (4) elements and there is no collapse. They work together.
Ignore _any_ of those four (4) elements and you will never understand the collapse. They work together.
Unfortunately that is four (4) elements which is at least three (3) more elements than many people who opine on this topic can handle at once. So often the discussion is stuck at the level of _impact damage_ *OR* _fire_ (time and gravity never even come up).
Impact damage alone obviously insufficient to immediately induce collapse, as evidenced by the fact both Towers were still standing after being hit and remained standing for a considerable amount of time. In fact, both towers survived _impacts_ that were 4 to 5 times greater in terms of _impact energy_ than the scenario considered back in the 1960’s. The planes certainly did not survive the impacts. They were decelerated from over 500 mph (Flight 175) to 0 in a fraction of a second and converted into millions of bits.
*That in no way implies the Twin Towers should come out unscathed or that they cannot succumb to additional accumulating damage over time* later.
Some people seem to get this bizarre belief that _survive impact = zero damage_ which is of course obvious nonsense. That is why it is so important to qualify these things.
*Fire* induces further weakness of the structure but that *takes time* to accomplish, it is not immediate. Over time and more and more of the structure gets weaker until it is no longer able to support the weight of the structure and *gravity* does what it does. Columns begin to bend as they get hotter and lose strength. We know (or at least should know - if you don’t then you shouldn’t even be in this discussion) that a straight column has more load carrying capacity than a bent column. Bend the columns too far and they will fail in Euler buckling.
And that is exactly what happened to initiate the collapses of both Twin Towers.
Now you know.
So, if that fire doesn't melt the steel, how come there is molten steele in the video even a week after the collapse?
3 months later.
@@fknbastages Right? Thermite because it was an inside job. Architects and engineers for 9/11 truth has lots of info and experts thag agree

@@wayland7150 something wouldn't be thermite as that would make me conspiracy theorist, antivaxer, flat earther, Trump supporter, Putin lover, Palestine apologist etc.
So how does this explain the collapse of the third tower which was never hit by a plane?
Damaged by the two towers that collapsed.
@@EchoAccord Where and how?
@@EchoAccord It was damaged on the roof, yet collapsed from the bottom.
Try and 'logic' your way out of that.
@@redpillaware5101 Have you ever wondered why buildings beneath the world trade centers were destroyed after the collapse?
Climate change
Thank you so much for such a detailed explanation. Your videos always inspire us. The quality and the way you represent things is just fabulous. Keep it up and thank you very much❤ ...
A highly ranked funded comment praising this propaganda piece. Nice.
Detailed? Steel buildings don't collapse onto themselves like a house for cards.
😮@@WillConley
@@Riley_rolo This pice of shite showed it colapsing from the bottom at ground level, they are trying to re write the event
@@EssentialComment notice the OP never responded? This comment section is a greenhouse of fake plants! 🪴🪴🪴🪴🪴🪴, don’t waste a keystroke on it . Buildings don’t turn into dust midair and debris piles aren’t 99%dust from building collapses.
Thank you for this physical interpretation video.
I can't wait for his Complete Physics explanation of Santa's reindeer.
Santa is more believable...
13:10 Nice model.
But the wing span of the 767 was 156 feet and the 757 had a wingspan of 125 feet and the tower was 208 feet wide. Your model makes the plane look as wide as the building.
pretty sure this is bunk and it was an inside job bud. i, like you, wish it werent so
@@ETIC-U Pretty sure those claims have been completely & utterly debunked mate so don't worry about it. The government can be ar5eholes & pretty corrupt at times, but they don't fly planes into skyscrapers to murder thousands of their own citizens.
But the height of hulk is 8 feet in his ultimate form.
This video makes it look like he’s as tall as wtc.
Fucking fake news man
@@AmazingRofa Spam
B767 is a relatively big plane but B757 is a single aisle narrow body aircraft which was as big as B707..
I think about the people on the very top floor and the ones who sat and watched those planes come right at them head on! OMG 😢😢😢 like nothing you can do
dammmn i never knew the hulk was that big irl or had anything to do with it
I'm interested in finding out why wtc7 collapsed in the manner seen in videos. Lesics said he would produce a video but he's not done that. I've looked through the comments but can't find any plausible explanations. If there is anybody that genuinely knows can they please explain why the whole of building 7 initially collapsed at free fall for over 2 seconds?
Hi Diana, I did reply to your question to me on the other thread but will address it here too in case you've missed it. The only section of the building that reached freefall acceleration was the outer facade of the building which became detached from the main structure. This was simply the result of buckling. Fire fighters stated that a collapse was inevitable several hours prior to it falling, it really was that obvious. The sprinkler systems had been compromised & no attempts were made to stem the blaze that was confirmed on at least 16 of its floors & the building was left to freeburn..the fire-proofing was rated at 5hrs if I remember correctly. It actually burned for 7hrs before it fell, 2hrs beyond this. The reason it collapsed in the manner it did was down to the implementation of longspan beams used to create a large, open atrium. Longspan beams are more susceptible to fire for obvious reasons. Hope this helps.
Dianna aren’t you lucky to have two replies from the foremost experts on building collapses answer your question so quickly . It’s almost hard to believe that they both would chime in together almost simultaneously! It must be your lucky day!!!!
@@dirkdiggler8260 Thnx for your reply here and on the other thread ❤️
I have replied on the other thread with a couple of queries. There is another other explanation here in this thread from You Tube Sucks but their explanation seems to be different from yours, which is confusing me🤔🤔
You say the facade was detached from the structure and they say that the external moment frame remained and this was the last part of the building to fall. Which is correct?
Also, you mention buckling but do not say which columns buckled or where these buckled. They say that column 79 buckled first then other internal columns buckled and that csused the collapse of the whole internal core structure and all floors which progressed into the collapse of most external columns until there was only 4 corner cjlmns supporting the external moment frame.
Is the the same buckling that you are meaning?
If the collapse of the whole building progressed from the failure of one intern column near the north east corner, can you please explain how a asymmetrical progressive collapse ends up in a symmetrical coolaose of the whole envelope of the building?
Also, how could the firemen know that internal column 79 would occur, which would lead to the whole building collapsing?
@@RUclipsSucks_1 Thnx very much for your detailed trply❤️❤️. There's loads of other interesting information you've provided in addition to just explaining the free fall collapse episode. I also have an explanation fro Dirk Diggler but what he says seems to be different from your explanation, which is confusing me🤔🤔.
I have a few questions but you say you only want one at a time. My first question is this. Is it your or Dirk's explanation that is correct?
@@dianax266 - Your interest is clearly genuine and you do not appear to be engaging in discussion killing shenanigans so _you_ may feel free ask more than one question at a time.
Dirk and I are both saying the same thing, just in different ways and I suspect Dirk will agree on that. Perhaps that is where the confusion is coming in - he and I are approaching the same issues from different perspectives, and in a different sequence.
For example: Dirk says: _The only section of the building that reached freefall acceleration was the outer facade of the building which became detached from the main structure. This was simply the result of buckling_
That is dealing with the same event I describe in *Phase 4* and other than degree of detail we are both describing the same thing.
_Phase 4 : After about 10 seconds only the exterior moment frame - a hollow shell mostly supported by the _*_4 corner columns_*_ and quite unable to stand on its own - remains standing_ (The interior structure was now gone leaving only this shell). _Casual observers falsely believe the building is still there since little has changed externally. They are wrong. The top center of the north face with nothing behind to support it leans into the big empty, forming a V shape in the roofline. Then the _*_few remaining perimeter columns inevitably buckle_*_ under the strain. The moment frame drops onto the top of the 7-story tall debris pile_
Central core columns have all failed and dropped, taking the floors with them, leaving only the outer shell - supported primarily by just the 4 corner columns which inevitably buckled and gave way. It was this hollow shell that was briefly measured at an _average_ of free fall for 2.25 seconds. And that information tells you nothing about why the building collapsed.
The collapse only gives the illusion of being "symmetrical" if you only pay attention to the outer shell (which looks like a building but isn't). The _building_ is the stuff on the inside, not the skin on the outside. Remember, the first 10 seconds or so of the collapse - all the internal failures - are all happening inside those four walls and you can't see most of it. This is the part most people find the hardest to wrap their heads around and is quite different from the Twin Towers where most of what is happening can be easily seen.
The FDNY did not have any idea where the failures would start, only that they would. Building 7 was clearly unstable and collapse was deemed inevitable. How and where the collapse started are details.
If you look at the footage, the second plane clearly crashes on the side of the building not down the center.
In other words, one side would have warped metal much faster and it wouldn't have neatly fell like that.
The top would have toppled on its side.
Footage clearly shows it did.
the top is going first to a side, and then 'somehow' straight down...
It doesn't work like that. Many hundred ton steel structures are designed to carry a vertical load and resist lateral wind loads while firmly supported at their foundations. Lean the structure even a few degrees from vertical and especially without full and even support from its base or foundation and it will crumble like so many toothpicks.
Man, the laws of physics don't change. If one side goes first, it should come down a little on it's side. It doesn't have to lean and fall sideways but at least it should come down a little on it's side. Not perfectly down like some one squashed it from the top.
Ever seen those failed demolition videos where not all the TNTs blow up, and the building ends up falling on its side?@@holdernewtshesrearin5471
@@sspanjersbergNewtons law of motion explain this behaviour. Once the top part of the building is no longer connect to the bottom part, the bottom part of the build can no longer apply a force to the top. That means the only force acting on top part of the building is gravity and gravity acts straight down, and the body then moves in the direction of that force.
The fact that the engineers actually tested plane crash physics is crazy
This makes sense
