Ukraine’s security service blew up a railway connection linking Russia to China, in a clandestine strike carried out deep into enemy territory, with pro-Kremlin media reporting that investigators have opened a criminal case into a “terrorist attack.”
The SBU set off several explosions inside the Severomuysky tunnel of the Baikal-Amur highway in Buryatia, located some 6,000 kilometers east of Ukraine, a senior Ukrainian official with direct knowledge of the operation told POLITICO.
“This is the only serious railway connection between the Russian Federation and China. And currently, this route, which Russia uses, including for military supplies, is paralyzed,” the official said.
Four explosive devices went off while a cargo train was moving inside the tunnel. “Now the (Russian) Federal Security Service is working on the spot, the railway workers are unsuccessfully trying to minimize the consequences of the SBU special operation,” the Ukrainian official added.
Ukraine’s security service has not publicly confirmed the attack. Russia has also so far not confirmed the sabotage.
Wasn’t that the reason though that the Twin Towers in NY fell, because the jet fuel melted the steel beams infrastructure?
I had read/seen that the buildings were actually designed to handle a plane crashing into them, but the architects didn’t expect the metal beams to melt from the high-temperature burning jet fuel.
My understanding is that the beams were sprayed with a fire retardant foam that is designed to protect it in the event of a typical building fire. But the violent impact of the jets would have stripped most of it off, and the jet fuel did indeed weaken the beams. They wouldn’t have melted outright, but softening them after already being damaged by the impact was more than it could handle.
That’s my understanding as well.
And that the fire retardant foam was designed to be hit by an airplane and stay on, but it was just designed in those days for a smaller 737 impact, and not for a heavybody plane, so it got knocked off, exposing the beams.
Edit: Lol, ok, meant beams, not beans.
Lemmy moment.
This lemming eatin beans!
Dammit put a NSFW warning on that post!!!
There could be children in here!!!
You guys are all government sheeple! Everyone knows the Twin Towers never existed and 9/11 was a hologram!
I stil remember going to a wedding reception on the top floor - it all seemed so real
A yes, a fire removedant.
It didn’t need to melt, raising the temperature of steel decreases it’s strength.
It is, is it?
It is strength that decreased
it’s its strenth that decreased
It’s a conspiracy theory, and not a particularly intelligent one. Us normies like to make jokes like this mocking people who believe it, but they do actually believe it and will come up with some batshit insane logic to support their theories.
I haven’t heard of anything to refute that, and have heard things to confirm that.
If you have any info you’d like to submit, please do so.
Edit: By refute that, I mean refuting that the jet fuel burning caused the metal to weaken onto collapse.
Well, here’s what 5 minutes of research yielded

https://www.steelconstruction.info/Fire_damage_assessment_of_hot_rolled_structural_steelwork#:~:text=All materials weaken with increasing,and 45%25 of its stiffness.
Jet fuel burns at 1500f, which is 815c. At 800c steel retains less than 20% of the strength that it has at room temperature. There you go, fully debunked with minimal effort and extremely basic facts.
The problem is, I read contradictory information, so both sides say they’re correct…
For example, this…
That doesn’t look like contradictory information to me.
I meant contradictory to the origional comment I was replying to, that was talking about alt reasons for the tragedy. Replied to the wrong comment.
The internet since 2001…? There’s reams of examples of people who believe this crap and have posted it. I wouldn’t be surprised if people have done PhDs where this conspiracy theory is featured heavily.
This particular one is amazingly stupid for anybody who’ve dealt with materials and heat in their life. Like making barbecues.
Just to make sure we are on the same page, are you saying that the jet fuel burning the metal beams of the building is true, or a conspiracy?
I’m saying the part of the comment you initially highlighted is a joke based on a well known conspiracy theory with no basis in reality. It’s been so long since I read up on it, the beams may not have burnt. They just may have been weakened by the heat. Either way, it matters not as we have pretty good evidence that the twin towers did fall after two planes loaded with fuel hit em.
From what I recall the heat from the burning weakened the structure and the entire floor basically collapsed onto the lower ones, this continued as each weakened floor couldn’t hold the weight until the buildings collapsed
Ah, ok. Thanks for the clarification.
Yeah it’s a really dumb meme because obviously it can. The ancient Romans worked steel, so obviously it doesn’t have a particularly high melting temperature.
Jet fuel can’t melt steel beams. It doesn’t burn nearly hot enough.
However, for a structure to fail you don’t need to melt the beams, and getting them hot enough will also damage their structural integrity; they’ll fail long before they reach the melting point.
And this is what happened on 9/11.
Even wood alone is capable of getting steel red hot under the right condition. Given my experience was with metal floor grating in a burn barrel. The steel became easily malleable with just a metal rod.
At the temperature Jet Fuel burns at, Steel becomes as flexible as cooked noodles, but technically they have not “melted.”
Also: worked metal heats up. So an entire building collapsing on hot beams can get them even hotter.

The conspiracy goes SO much deeper… it’s rumored that even physics is involved.

Melted beams or not, the WTCs design is what made it collapse like a peeling banana. The floors were essentially cantilevered out and held in place with a load bearing facade (for an open floor concept) There wasn’t much holding the floors onto the facade, once the weight of the floors began to sag down it essentially started to lever and pull the beams of the central core apart from all sides like a banana peel.
I don’t think those buildings were built to withstand an airplane, at least not the one they were hit by. In hindsight that open floor concept may actually have been a stupid idea, at least the way it was executed.
From what I saw on a show that covered that a long time ago, they were, but not for the larger planes that we have today, but the ones that flew back in the 70’s.
