Wake up. The antenna was not part of the Soviet Union's radio communications. He was in Poland. It was a Polish radio station, not a Soviet one. The antenna was not located in Warsaw, but in Konstantynów.
I apologise for mistakenly labelling it as a Soviet radio mast, for some reason I thought Poland was part of the Soviet Union... geography is not my strong suit. I will do more research next time.
@@Contraflex No, no, we were a seperate country in the Eastern Block (economic/military ties with Russia back then) Thanks for the video. Cool that you're interested in old radio towers 😂😂 Ever thought of becoming a tower technician ? ;) (I think it's a cool thing to do for a living, climb these towers) Anyhow, best wishes to you 😊
Thanks to the Warsaw Antenna, the 629-meter KTHI-TV tower in Blanchard, North Dakota has the distinction of twice being the tallest structure on Earth: from its 1963 erection until the Warsaw Antenna's completion in 1974, and then from the Warsaw Antenna's 1991 collapse until Burj Khalifa "topped off" in 2008. The Blanchard tower, now KVLY-DTV, still stands sixty years later.
@@Contraflex Theres a wonderful TV episode on Big Machines, with a HD cameraman going to the top during an antenna replacement. Got a twinge of vertigo just watching it on 720P. I see theres a nine minute piece on TowerandTurbine channel on UTube.
Thanks for the feedback, this was made using Blender and the "Bullet Constraints Builder" add-on. There is a great tutorial on how to use it by RUclipsr "EarthquakeSim".
@@Contraflexholy crap :0 I was joking in my head saying "pushing the limit of blender by recreating the collapse of this tower" didnt suspect for it to be actually simulated in blender!
There are different stories about the collapse. I personally read of successfully replacing the main rope with two temporary ones, but then hours after workers left the area one of the temporary ropes slipped off of it's clamp, causing the disaster. This is why there were no killed or injuried, as everybody had left the site prior to the collapse. Also I heard that the signal wasn't getting it's way to the Antarctica, but it could have been received in the north and central Africa. The mast was never rebuilt, after years of waiting they finally replaced it with another one (actually an array of two "half-wave" masts) near the city of Solec Kujawski (/solets kooyavski/). You can still receive it at 225 kHz, AM band of course. It's not as powerful as the old one, but I believe it still covers most of Europe and maybe even larger area. Greetings from Poland.
Thank you for the information. I researched this video primarily from the English Wikipedia article, I imagine I would have missed a lot of Polish sources that have more information. Your account of the collapse definitely seems possible and would explain why no one was injured despite the scale of the collapse. I am glad to hear the replacement masts still have such impressive transmission capabilities.

Yes, the collapse appeared to be localised in a small radius near the base of the tower. If anyone was in the vicinity during the collapse, I'm sure they would have had sufficient time to run away from the base and avoid being struck.
Excellent presentation! I love these kind of computer simulated disaster recreations. Very well done. I feel lucky to be subscriber #310. You're channel will be in the 10's of thousands (and beyond) in no time if you keep this kind of production quality!
In Poland, we generally liked to broadcast the radio. We had several transmitters capable of transmitting signals far beyond the horizon. And every time some man had to ruin it. (babice transatlantic, several radio broadcasting centers disrupting propaganda radios from the west during the USSR)
I'm not aware of any images showing the entire footprint of the collapse, but some close up photos show large sections of the tower remained intact, similar to what is seen in this video.
"We'll detach the Cable that needs repairing, and then, attach the temporary support Cable's...." Even just the idea of it, is enough to tell you that it ain't a good idea, to not have attached the supporting Cable's before, they disconnected the main support Cable
@@Contraflex The illustration pretty much demonstrated that particular scenario......there was no reference made to any support Cables being attached to the Tower before the damaged Main Cable was released for repair...."if that's what really happened", then..."the repair methodology Was seriously flawed..."
@@Contraflex Maybe the decline of broadcast AM/FM, but of radio? In the current era of wireless Internet and phone connectivity, I'd say there's more radio than ever.
@@Tacticaviator7 They use all kinds of bands going from microwave right down to UHF. Part of the old analog TV spectrum here (800mhz) is now used for 4G comms. In any case, theres still a ton of radio spectrum in heavy use, just different use than it was maybe 20-30 years ago.
@@technicalfool well generally "radio" as a term is used for AM/FM transmissions, so it's close enough. Yeah, cell phones still use towers, but I don't think "masts" are being built as commonly as before. We have satellites now, and there's no wider range than a transmission in space.
Great Video! Apart from the first part where you said its in the soviet union its a well explained and shown video. I don't see many people talk about this radio mast, barely anyone knows Poland had the tallest structure, so many thanks for sharing! It seems sometimes like inventions from Poland, especially unqiue ones, are supressed by the media and internet.
Thank you for your comment, and I do aplogise for misspeaking about the soviet union. Yes it is a shame that more people don't know about this incredible mast.
The guys that changed the lights on that tower had it easy with that elevator. I've met some guys who change light bulbs on towers next to where I live, and they have to climb the side of the towers by hand. After talking with them I was like, "Nope, I'm not in good enough shape to do that." The towers near me are like maybe a third, or a fifth, or an even smaller fraction of the height of that tower, but that's more than I wanna mess with. I wouldn't mind going that high, but not under my own power thanks. :P
I'm friends with the engineer that worked at our local TV station. He said their tower has an elevator however I believe he said it only takes you halfway up. You have to climb the rest of the way.
@@badcompany-w6s No, ... traditionally, we change a bulb by three men ... two turning a ladder and the third holding the bulb. That's why, to keep the tradition alive, the second half of the tower has no lift.
RCN Konstantynów radio transmitter site was NEVER a part of any Soviet Union communication system! It was a Polish AM broadcast radio station. Edit: Another correction: The transmitting center had not one but two Swiss-made Brown-Boveri transmitters. Each transmitter produced 1MW of output power. A combiner circuit was used to merge the outputs of two transmitters, resulting in total of 2MW of output power sent to the tower. Another correction: the elevator on the tower was powered by a 4-stroke, 2-cylinder GASOLINE, not Diesel engine. Another correction: The cause of the collapse was a temporary guy wire that slipped out of its ground attachment, which increased the load on the remaining wires, causing them to fail one-by-one. The root cause of the collapse was gross negligence and incompetence of the crew performing the work on the tower. Your animation is correct and impressive. I wish you had put more time into researching the facts.
Thank you for correcting many of my mistakes. I apologise for the inaccuracies, in my defense there were not many good English sources on this topic. I am glad you still enjoyed the video though.
you have a good cam eye, fren; very natural, very thorough, always just the rt framing, esp w a moving cam eye following the crash down to ground; seriously impressive cam work.
this story sounds very similar to how the Arecibo Radio Telescope met its demise. The main receiver was held up by steel cables so it could be adjusted around the dish. those cables were left to rust and rot in the Puerto Rican sun for decades without any kind of preventative maintenance. then a few years ago, one of the three cables started to break, and the receiver plunged into the dish. It was a sad day for radio astronomy and astronomy/cosmology in general.
Is it possible to validate the result of this simulation against images of the collapsed tower? As someone who has worked with computer simulations, many people assume that a simulation is correct simply because it was done on computer with a visually impressive model, when in reality boundary conditions and assumptions can make enormous differences in how the simulation plays out.
I definitely agree with you. If you put garbage into your simulation/model, you will get garbage out of it. Additionally, if I had chosen a different cable to detach at the start, I'm sure the collapse would have looked entirely different. However, the goal of this simulation was less scientific and moreso for entertainment/educational value. Still, you will see in photos of the real collapse that the mast remained in large undamaged segments as seen in this video.
This is fascinating and a great video. I don't understand from an engineering perspective why there wasn't redundancy in the design. It seems like losing one guy wire should not cause an almost immediate catastrophic failure of the structure (I know there were other factors involved, but still). You would think the structure itself should be able to resist some deformation, and that the numerous guy wires are simply there for added stability. But then, I'm not an engineer so what do I know XD
I think under normal loading conditions, the failure of a single guy wire would not cause the entire tower to collapse. However, once the tower was struck by the extreme wind gust while the guy wire was missing, it resulted in the tower being displaced enough to cause progressive collapse. It likely would have been too expensive to design the tower to survive this extremely unlikely scenario; a potentially one in one thousand year wind gust happening at the same time as a guy wire being replaced (which would presumably only take a few hours to replace). Technically the structure could be designed to withstand a one in one thousand year wind gust without any guy wires, but it would require extremely large steel members and would be very expensive; at that point you are no longer designing a guyed mast, you are designing a skyscraper.
perfect work man keep going im supporting you 👍 its remind me of BATTLEFIELD 3 caspian border map when the antenna tower fall .... can you make a video about it please ? and thanks ❤
Great stuff, just keep at it mate! You'll be one of the biggest infotainment channels on YT if you keep it up for a year or two! I remember watching first Real Engineering videos and seeing a spark of potential in the creator. I see the exact same thing here!
The KVLY mast lost about 75 feet of height in 2019 with the replacement of an antenna. Its neighbor in Galesburg, North Dakota, the KRDK mast, now holds the title of the tallest structure in the Western Hemisphere, if you don't count the underwater Petronius Platform. KRDK was only 3 feet shorter than KVLY's original height. I should really drive over and see it sometime, since it's in my state.
I believe that more then the wind, removing a set of guy wires on one side would cause a tremendous 'offset' to the others still attached to the tower. Their collective WEIGHT alone would pull the structure over for sure!
Nah, air music is a different one, the less intense version of "We were set up", so that way when you in the air it can instantly transition to aerial chase music when you're wanted This is menu music, the one you hear when your game is paused
Really like the delve into turbulence and vortex shedding and how this creates resonant oscillations in the tower. My masters dissertation was on vortex generation and shedding but in a quantum fluid of superfluid He4 where the difference between turbulent and laminar regimes is very discrete compared to classical fluids. Great and interesting video, hope to see more from your channel in future.
Thank you for sharing, that sounds really interesting. Are there any machines or systems where He4 vortex shedding is an important consideration, or was your research more theoretical?
@@Contraflex It was mostly academic but these things called remnant vortices (permanent vortices formed when the superdfluid is made) are a bit of a hindrance to experiments for new theories surrounding superfluid He3 and the idea was to create a device that could shed these remnant vortices. We were essentially developing a device that worked in He4 (because its MUCH cheaper and easier to work with) before using it as a probe of He3. If you want to read more about it, look at surpassing Landau Critical Velocity in He3. Lancaster Uni in the UK does a lot of research on it.
No blueprints, just looked at photos online. The modelling process took at least a month, but the simulation only took maybe 1 hour. Ryzen 5 5600X and RTX 3070 (although the simulation is CPU only unfortunately)
@Contraflex very good work there is a guy that made a manila envelope Boeing 777 model using pictures but it looks like he used blueprints from the airplane manufacturer you can find his videos on RUclips.
@@Contraflex it maybe but it is still wrong and you should do soemthing like that u chimp. Simplifying things is something wrong and normal people should be avoiding doing that
As a polish I have to be honest - you deserve more views here, well done video and well explained. I think it's a shame we caused a disaster like that, the tower could still be standing there today. Edit: by the way yea, it's a polish tower placed in Poland, np 😅
Thank you for the kind words, I assume you are referencing the Warsaw radio mast video... unless the Poles had something to do with Grollo tower as well 😂
I love how there were people who said that this mast caused health problems to them, eh... the stupidity. Also there is a 36 minute material about that mast in Polish, but it has English subtitles too iirc - its worth to watch it.
I guess the point I was trying to make is that despite it being really fragile, it was still really powerful. Like a wand from Harry Potter, you can snap it in half, but at the same time, you can use that wand to do crazy shit. I don't know bro...

Technically the towers were not the tallest when they collapsed, you make a good point however.
Bro put GTA V pause music on the background and thought we didn't notice?! 😂
Respect. 🗿
Thank you brother
People who heard the gta 5 pause/map music
My dad took me to see that antenna, back in 89-90, as a kid, seeing the whole structure in a daylight, was almost overwhelming.
Thank you for sharing, that must have been incredible.
We using the gta v pause background music with this one 🔥
The GTA V pause music fits well with anything
@@Contraflex Not as much as Undertale music, but anything sad/relaxing goes
GTA V pause music nostalgia hits hard but in a good way lol
Combined with tall towers collapsing is fascinating AF.
I'm glad so many people appreciated the background music
perfect work man keep going im supporting you 👍
its remind me of BATTLEFIELD 3 caspian border map when the antenna tower fall .... can you make a video about it please ? and thanks
❤
I definitely thought of that BF3 map as well when I made this video. Thanks for the feedback!
Great stuff, just keep at it mate!
You'll be one of the biggest infotainment channels on YT if you keep it up for a year or two!
I remember watching first Real Engineering videos and seeing a spark of potential in the creator. I see the exact same thing here!
Note for my future self: I'm the 227th subscriber here )
Thank you so much for your words of encouragement, it means a lot! I look forward to making more videos when I have the time.
Is that the GTA V menu theme as background music?
Indeed!
The KVLY mast lost about 75 feet of height in 2019 with the replacement of an antenna. Its neighbor in Galesburg, North Dakota, the KRDK mast, now holds the title of the tallest structure in the Western Hemisphere, if you don't count the underwater Petronius Platform. KRDK was only 3 feet shorter than KVLY's original height. I should really drive over and see it sometime, since it's in my state.
Thank you for sharing! I would definitely visit it if I was that close
I believe that more then the wind, removing a set of guy wires on one side would cause a tremendous 'offset' to the others still attached to the tower. Their collective WEIGHT alone would pull the structure over for sure!
That's a very good point, I'm sure the unbalanced lateral forces resulting from the weight of the guy wires would have contributed to the collapse.
Awesome video! Thank you for your work.
Good thing no one was working on the tower at the moment of collapse
Very lucky indeed!
I played Battlefield 3 so I’ve seen the worlds tallest tower collapse. 😂
Caspian Border was a great map!
I know I ain’t tripping is that the gta menu music?
You are 100% correct
Yup
him: talking about the background of the tower
me: "ooh, gta 5 air music"
Nah, air music is a different one, the less intense version of "We were set up", so that way when you in the air it can instantly transition to aerial chase music when you're wanted
This is menu music, the one you hear when your game is paused
I wonder what would happen if the wires didn’t have lights a plane would probably tear them apart
I would be more worried about the plane, I think the wires would cut the thin aluminium fuselage in half.
Really like the delve into turbulence and vortex shedding and how this creates resonant oscillations in the tower. My masters dissertation was on vortex generation and shedding but in a quantum fluid of superfluid He4 where the difference between turbulent and laminar regimes is very discrete compared to classical fluids.
Great and interesting video, hope to see more from your channel in future.
Thank you for sharing, that sounds really interesting. Are there any machines or systems where He4 vortex shedding is an important consideration, or was your research more theoretical?
@@Contraflex It was mostly academic but these things called remnant vortices (permanent vortices formed when the superdfluid is made) are a bit of a hindrance to experiments for new theories surrounding superfluid He3 and the idea was to create a device that could shed these remnant vortices. We were essentially developing a device that worked in He4 (because its MUCH cheaper and easier to work with) before using it as a probe of He3. If you want to read more about it, look at surpassing Landau Critical Velocity in He3. Lancaster Uni in the UK does a lot of research on it.
Omg I know that GTA 5 story mode map screen music from 1000 miles away🤣🤣 !!! Many many many many all nighters spent.
I'm glad it brought back some memories for you
Gta5 menu theme.
Just 5mins ago played this masterpiece.
It will always be a masterpiece
Nobody noticed the gta pause menu music?
I did..
I sure did.
Great video! Really interesting story, and explanation of the science behind it.
Thank you so much for your feedback!
gta menu music background whaaatattt?
Came for the planes vs building jokes , realised i was too early to find them , i will let teenagers do the job now !
came for the radio tower collapse, stayed for the gta v pause music
So many viewers have commented on the music; I'm glad I chose it.
@@Contraflex It's pretty famous
Not NEARLY as much as Undertale music but still, the OST is something out of this world.
Great work! Great story!
Thank you!
2:18 bro fell 😭😭😭
Bro wanted to end it all...
Many thanks for this video and regards from The Netherlands.
Thanks for watching!
Suddenly i want to play gta 5
Give it a year or two and you'll be able to play GTA 6 instead...
@@Contraflex Less than a year
It's gonna come out in 2025
Girls: I can't believe he didn't cry at the Titanic! Do men even have feelings?
Me: ...
🤣🤣🤣
In the start of this video are you using GTA V loading music?
The entire video uses the GTA V main menu music. I find it nice and ambient, and as a bonus RUclips doesn't flag it for copyright.
I found the spaghetti snapping amazing.
now lets do the experiment in real life
There's plenty of footage out there of smaller radio masts collapsing.
How did you get blueprints for the tower to make the simulation and how long did it take and what kinda hardware do you run.
No blueprints, just looked at photos online. The modelling process took at least a month, but the simulation only took maybe 1 hour. Ryzen 5 5600X and RTX 3070 (although the simulation is CPU only unfortunately)
@Contraflex very good work there is a guy that made a manila envelope Boeing 777 model using pictures but it looks like he used blueprints from the airplane manufacturer you can find his videos on RUclips.
This is triggering an internal megalophobia and acrophobia that was also triggered watching the trailer for Fall.
I'm sorry to hear that, but thanks for teaching me two new words!
Background music sounds so familiar yet nostalgic
@@-FreeMiner- it's the GTA V loading screen music, perhaps you heard it there
@Contraflex thats there, not played it in years
It's called RCN Konstantynów, not Warsaw radio tower...
Thank you for clarifying. For international viewers I think Warsaw Radio Mast is clearer.
@@Contraflex it maybe but it is still wrong and you should do soemthing like that u chimp. Simplifying things is something wrong and normal people should be avoiding doing that
love the song u chose for this video not many use this from gta 5 and it's super underrated
if nobody dies i don't think it was a problem...
“Cost to rebuild” am I a joke to you? 💀
Did you know how much money it costs to build such a thing
As a polish I have to be honest - you deserve more views here, well done video and well explained. I think it's a shame we caused a disaster like that, the tower could still be standing there today.
Edit: by the way yea, it's a polish tower placed in Poland, np 😅
Thank you for the kind words, I assume you are referencing the Warsaw radio mast video... unless the Poles had something to do with Grollo tower as well 😂
I would probably die before I reach the top 💀
The Grand Theft Auto V pause menu music is a nice touch.
thanks dude!
I love how there were people who said that this mast caused health problems to them, eh... the stupidity. Also there is a 36 minute material about that mast in Polish, but it has English subtitles too iirc - its worth to watch it.
Thanks for the recommendation, I will check it out
I came here to hear the GTA V pause menu music while watching the antenna collapse
It's a great song, very nostalgic and pensive.
@@Contraflexthat’s true
imagine base jumping from that lmao
I wouldn't be surprised if someone tried it
It's energized
You'd die trying
Good explanations and animations! Good luck!
Thank you for the kind feedback 👍
The GTA pause menu music is on top. Love it. ❤
1:50 Ahh yes, it might seem fragile because of its slenderness, but it made up for that by emitting radio signals… I see…
I guess the point I was trying to make is that despite it being really fragile, it was still really powerful. Like a wand from Harry Potter, you can snap it in half, but at the same time, you can use that wand to do crazy shit. I don't know bro...
I know Gta V pause music when i hear it
Am i able to add the music to my songs playlist or is it something that you made please tell me
The song is from the GTA V Pause Menu, feel free to use it.
@@Contraflex thanks
GTA5 background music....nice
Is this a computer simulation or a game simulation?
It's a simulation in the 3D animation software Blender using the Bullet Constraints Builder add-on.
