>>739000505 does anybody ever take into consideration the fucking jumbo jet that slammed into them may have caused a little structural damage or is intentionally being as stupid as possible what the kids do here nowadays?
>>739001265 that would make since if those damn jets slamed in-between the first 20 floors. No way one jet that hit the upper floors could take down a high-rise. also compare building 7 with that one building that caught fire in Europe recently. By B7 standard, that England building would have collapsed.
>>739001265 funny thing is, the towers were designed to take such a hit from a plane of that class. yet their foundations collapsed the same time the top of the towers collapsed...you dont have to be a rocket scientist to understand something is not right
Around 2500F before steel liquefies, however it varies depending on how much iron is in the steel.
And to answer the stupid fucking meme question, steel loses its structural integrity long before it reaches its melting point, so combine all the damage to the foundation caused by the jumbo jet slamming in to the building with the burning fuel destroying the integrity of the remaining supports, and then have the giant chunk of twisted steel and concrete that made the upper floors come crashing down when even a single floor collapsed and you have a chain reaction that would collapse the entire tower.
Bush may have done 9/11 but it was done with the fucking planes and nothing else.
>>739001739 yeah, you'd think the huge mass of the lower 3/4 of the building would stop the falling top 1/4. The top section should have met some resistance on the way down and fallen off to the side, instead of the whole building just turning to powder in 5 seconds.
Also if you are going to claim that this is proof of thermite or whatever, in order to bring the buildings down you would have had to see these waterfalls of molten steel all over the place. Also this is a shop.
>>739003577 why? 2 planes have hit, another's hit the pentagon. Another has crashed for the nice hero story. Job's a good'un!! Only thing the demolition achieves is that thousands more people are needed to execute the plan and cover it up...and the risks of getting caught increase a billion fold. Easy plan = recruit hijackers via proxies and give them a helping hand to not get picked up. Half a dozen people needed and even the hijackers don't know they're recruited by CIA.
Dumb truther plan? Thousands involved in the most complex conspiracy you could ever imagine...risking the overthrow of western civilization if they're caught...and for what?
There were subsequent side way firing of jets coming out as each top floor was collapising. If you look at the real controlled demolition videos, you see the same effect. It was controlled demolition. You cant refute that fact as engineering experts mentioned it in their comments. The collapse was planned well in advance of the event.
>>739003958 >and for what? War is extremely profitable for a select few. The conspiracy shit is dumb, but so is that question. Let's not pretend the US government hasn't lied to the public in order to wage war before.
Windows being blown out by the air being forced down through the building....if it was thermite there's no "bang". If it was conventional explosives there'd be det cord and probably unexploded charges everywhere. Plus the plane impact would have dislodged them or set them off anyway. Pick one..
>>739004158 a select few...not the thousands needed. Very specific thousands...not like robbing the corner shop where any two random idiots can be roped in. You need thousands of very specific psychopaths who are in the right jobs...very high level jobs. And you can't tip off the non psychopaths as otherwise you get caught and strapped to a gurney...keep thinking, you'll get there in the end.
>>739005050 As a member of a demo crew from Pittsburg I can tell you that each tower that fell did not do so due to an airplane. And I might add that tower 7 was not touched by flame nor plane and still went and conveniently crumbled. This was all structure removal and could not have been done without planning around building schematics with regards to finding structural points to place demo charges. The integrity of a structure will never be compromised from the top but always from the bottom.
>>739005475 You said a select few would profit....I said that's irrelevant. Obviously a select few can profit from anything. My point was that "for what?" had to apply to the thousands of people necessary for THIS conspiracy. Your pointing out of how a select few could profit was not an answer to the point I made....it's clear that you're the dumb motherfucker.
>>739005494 >As a member of a demo crew from Pittsburg I'm assuming you weren't in new york that day. I'm also assuming you have never actually read the NIST report, nor have you done any actual scientific research on the matter. I'm also assuming you barely understand half the physics at play in this enormous disaster. For those reasons I will ignore everything you claim to "know", and laugh in your general direction. Feel free to prove me wrong.
>>739005604 Close, it lowers the tensile strength. A large number of external colums were sheared off when the planes hit, transferring loads to the remaining columns. The tensile limit of the remaining columns lowered as they heated and the steel softened, until they could no longer carry the loads they were under, and they failed in a cascade, with a few going first and adding loads to other members which rapidly failed.
>A measure of abnormal long put volume was also examined and seen to be at abnormally high levels in the days leading up to the attacks. Consequently, the paper concludes that there is evidence of unusual option market activity in the days leading up to September 11 that is consistent with investors trading on advance knowledge of the attacks. —Allen M. Poteshman, The Journal of Business
>>739006234 They were only ever going to fall downward like that, but it wasn't due to intention. That was just the nature of their design. The WTC towers were built unlike almost any other large building with their center core design and flush sides. Look at other skyscrapers like the Empire State Building, Sears Tower, or pretty much any other and you can see there's layers to them. They are not the same width from top to bottom and inside there is a skeletal structure of steel. The WTC didn't have that. It has a hardened core with the elevators and staircases and then the exterior columns. Because of that when the floors collapsed they pancaked and there was no point where thy could have stopped.
>>739005897 I'm an authority on demolition, your assumptions are just assumptions. I can say that in my tenure in this position did not teach me everything I need to know about this subject but it helps that I have degrees in civil engineering and architecture in addition to other subjects.
>>739004779 Some principles are the same, cause is different though. In a demolition, you might blow out the steel columns with charges...on the other hand, a hot kerosene fire (that's what jet fuel is) could just heat up the beams until they started to get pretty bendable. Ever notice how beams in houses are made of wood? It's because wood doesn't get all bendy when it's hot...firemen can tell how weakened a wood beam is by looking at how much is left....not so much with a hot metal beam. Check it out for yourself.
>>739006537 Ha! Also further forgot to add that there is a real 9/11 conspiracy but it doesn't involve superthermite. The real 9/11 conspiracy is that everyone in Washington knew Saudi Arabia was culpable in the attack, but we couldn't say anything because we need SA and the gulf states to keep selling oil in US Dollars. So we pretended Saddam Hussein was responsible.
>>739005744 They WTC had an aluminum cladding. That's what made the exterior shiny looking.
>>739006463 In my classes I was told the number to be aware of was 1,000 degrees F. That's the point where unprotected steel being heated will start to sag and lose its structural integrity. Melting point doesn't matter from an engineering or firefighting standpoint. That 1,000 degrees was easily attainable in a fire with that much air, stuff to burn, and that was not having any water applied to it. It was only a matter of time until it failed.
>>739006603 >authority on demolition kek, so not a physics major then, or anybody I should take seriously? Got it, thanks for admitting. Feel free to prove yourself through science, I'm sure NIST would love your input. Oh no wait, NIST is part of the illuminati right? Fucking idiot.
>>739006842 so why haven't these buildings that burn for 12 solid hours collapse? E,g Grenfell Tower, The Address Bldg Dubai, etc. They were full of flammables too. Except the Twin Towers collapsed after just 40 minutes of fire.
>>739006696 Because the buildings suffered heavy damage prior to the fires even starting just from the plane's impact. Other large buildings that have burned had their structures intact and were able to cope with the fires. While it's true the jet fuel burned off very quickly (most exploded outside of the building) those quick fires ignited the building's contents and with the standpipes/sprinklers knocked out the fires were able to spread freely.
>>739007030 15 years, compared to you I'm Albert fucking Einstein on the subject. You want to come at me? Come do the job, we,will see how much you know. Shit I'm a foreman, ill fire you in a second you pleb.
>>739007042 Did those towers also have an airplane worth of jetfuel to burn? And did they also withstand the impact of a passenger jet before said fire? Or were those situations not comparable at all to what happened at the wtc?
>>739006749 did you miss everything else or something? im showing you so you can break though the think film of lies, to show you the 9/11 attacks though a difront perspective. dosnt mean im right or that the video is right. but its really weird.
>>739004132 You know there's a ton of low grade metal in buildings too right? the frame that holds up the little squares of ceiling tiles is shitty cheap metal, the air ducts and electrical wiring and tubings are all made of metal that I am certain isn't high grade steel. I think it would be weird if some molten metal didn't pour out of a gaping flaming hole in a building to be honest.
>>739007330 >did you not keep watching after such a moronic opening? No, no I did not. With an opening like that you know every word in the rest is pure drivel. An open mind does not mean believe everything some moron on youtube says.
>>739006942 Did you know? Silverstein's rent was $100+ million a year to the Port Authority, and he was responsible for paying for any damage repairs or reconstruction that would be needed during his time as the leaseholder. Those rent payments didn't stop because of 9/11. He had to keep paying them, as well as paying for demolition of the other damaged buildings of the complex, and paying for the new complex to be built. Very quickly those numbers would eat up that 4.5 billion.
>>739007484 You can't call bullshit if you never studird the subject or did the job. I'm telling you out of my experience in the field that these Fuckers are designed to withstand almost anything and it takes planned structural demolition to destroy them in the fashion they went down. Its textbook everyday shit to me. So when I tell you I am an authority on the subject open your ears and cram your partially informed notions.
>>739006789 No, once one of the floors starts to collapse, you've now got perhaps 10-20 floors above that moving down too. They're gonna keep going even if the floor below is still sound, because 10-20 floors falling 10 feet can pick up quite a bit of momentum.
>>739007813 wouldn't that momentum be absorbed/reduced by the rest of the building as the top part falls? The top part falling is hitting resistance with each floor. Perhaps a few floors would buckle sequentially, but at some point the momentum would slow...right?
>>739007042 The twin towers were an innovative, lightweight design where loads were carried by external columns and an internal bundle of columns supporting the core/elevator shaft. When the planes hit, one of the four exterior walls was sheared off completely, the opposite wall was partially blown out, and presumably a lot of the center columns were sheared off as well. So something like 60% of the columns were carrying 100% of the load, after being softened by fires started by a couple thousand gallons of aviation fuel and sustained by floors of burning office furniture, carpets, etc, they had all they could take and let go.
>>739005535 Look it up. Steel melted. Plenty of photos and video on the subject. Also even the sites trying to debunk the conspiracy theories admit there was plenty of molten steel under the rubble. I don't know what happened, but at this point do you still believe everything you are told?
>>739008043 Dynamic loads. The floors were secured with only a few bolts connecting them to the exterior columns and center core. Once one floor fell, it would land on the one below, cause a quick amount of stress, break those bolt connections, release that floor, and so on. Because every floor was built the same way and had the same dimensions, there was no point for it to really stop.
>>739008043 No, because with each floor that collapses, you've got one more floor's rubble (so the mass of falling debris is growing with each floor) and that (now bigger mass) has ANOTHER 10 feet to pick up speed again before floor 'n-2'..then 'n-3'... etc.
>>739008500 But by that argument wouldn't the collapse of the building look different than it did? If the floors collided and caused the next floor to fall, wouldn't there be noticable 'bumps' as it falls?
>>739008668 Because there's nothing holding them taught and upright. Buildings are systems that need to be intact to work properly. without the floors holding everything together then the exterior columns and core were just sitting in the wind. With the collapse of the North Tower, you can see for a few seconds a bit of the core standing upright before it too collapses.
>>739008496 >I don't need to _____ to jump to assumptions. Your argument is retarded and makes you sound like an arrogant asshole. If it's so stupid, watch it and list off reasons why it is. That's what smart people do. Ignoring opposing views will just make you dumb.
>>739000505 >How hot do steel beams have to be before they melt? How do you know this is steel and not another metal? Also have a picture of an burned Audi car that got torched at the G20 protests this year. What, you ask, where is all the metal from the car? It got an aluminium frame, you know the stuff planes are made of. The aluminium melted and started burning.
The force of the rubble falling from above is enough to break the structure, even if it wasn't damaged. This isn't people walking on the floor, it's like 10 stories worth of building that's been falling for about 10' (the distance between floors). Now repeat this operation for the next 60 floors, until all the rubble is in the basement.
>>739009237 That's like saying a scientist looks at a tiny bit of the results of an experiment and makes a 'conclusion.' You can call it what you like, but it's an incorrect/uninformed conclusion nonetheless. I'm not trying to change your opinion. Acting like an asshole can only hurt yourself.
>>739000505 Melt into slag like was found in the wreckage? Hotter than petrol can feasibly get entire sections of a skyscraper. Thermite charges on the other hand are designed to cut and melt steel and produce puddles of molten slag like was found in the remains of wtc1 and 2, and 7, which no plane ever hit but fell in anyway.
>>739009546 >experiment lolwat? We're talking about a youtube video you braindead idiot. It's a source, and as anyone can tell after 1 minute, a very non credible one. You're so goddamn stupid that you can't even follow simple logic, what the actual fuck?
>>739009546 leave the ignorant man alone hes obviously in the right and know everything there is to know about the topic, >>739009824 im so sorry i triggered you into this augment, my bad, here have another blue pill and go back to sleep.
>>739009707 You mean there is no chance of finding aluminium in a skyscraper that just has been hit by multiple tons of aluminium in form of an airplane? Did goblins stole the aluminium right after the crash?
