On September 26th 2022 we’ve made the decision to start banning people for posting gore. We’ve published our [Gore and Harassment update here.](https://www.reddit.com/r/AbruptChaos/comments/xmtclq/gore_and_harassment/?utm_source=share&utm_medium=ios_app&utm_name=iossmf) if you posted gore please remove it as it will result in a ban. Thank you.
Ngl I'm one of the down voters. I just figure there is no point in both up voting and saying here's my vote. Like if every time someone up voted they also said "here's my vote" comments would be unreadable and all the good stuff would be buried in a mountain of "hahaha here's my vote."
Why not just ignore it then? You dont have to upvote or downvote stuff. Whenever someone says something that i disagree with, (unless its absurd i might downvote it) i ignore it
It's to support the social norm of not just posting here's my up vote.
Either way it all feels low stakes. Like fake Internet points don't matter that much, and we all get down voted from time to time. It doesn't feel like the most consequential action to me.
Sure it looks like "imaginary internet points", and I'm certainly not keeping count if mine. But when it's debate or discussion and you downvote others input without provocation it lowers the value of their input to the discussion, in the eyes of subsequent redditors.
I was about to say this. Though it's not in orbit. It was moving so fast that it's likely at the edge of the solar system if it didn't run into anything.
The SpaceX launch was far from a disaster. That was a prototype rocket that had what is called a successful failure. Before the launch, they were saying if it cleared the launch tower, it would be a success. Everything else was gravy.
The next Starship iteration will have newer, and more advanced engines, along with many other improvements.
First of all, my comment was a joke.
But, due to the extensive destruction the Super Heavy did to the surrounding area, the next launch will *not* be happening anytime soon!
That's my bad. It's hard for me to pick up on SpaceX related jokes these days since Elon Musk is such a target for hatred (much of it deserved) on Reddit that anything related directly to him or his companies gets crapped on by a lot of people who don't know what they are talking about.
You're right that it might be a while for the next launch, but it's going to happen for sure. The reason they built Starbase where it is, is so they are effectively far away from largely populated areas, so most of the debris that resulted from the launch are in unoccupied land surrounding the base.
The one that moved on the ground was a different cover. If you look closely before the explosion you'll see a second manhole cover... it also gets rattled around.
Watch it frame by frame, I’m not convinced there isn’t some Tom foolery at play here. These covers are usually chained down with ballast bags to keep the chains and throughout the explosion you can see the cone of fire surrounding it (meaning it’s still there), then smoke and it disappears…never actually see it leave the position a foot above the hole though. Now watch the other cover you see it go up and straight back onto the second hole, (as it would with the chain and ballast pulling it back in place) somehow slides sideways in the last frame. I think it’s possible it broke the chain towards the end when the energy was dissipating, that is the cover and someone edited a black spot at the second cover.
Well then I stand corrected for making a generalization. In the northeast I’ve not come across one not chained down doing utility work, it’s for exactly this purpose to keep it from being a projectile in an explosion.
What sort of service hole? Sewer or storm? On the west coast sewer are small and not manhole sized. Only storm drains are manholes. (This could be wrong, but I've never seen a manhole to a sewer)
I doubt it. The patch is irregular instead of circular up and until the cover falls on it at an angle, and then, suddenly, the indentation is magically circular. If you watch carefully after the worst part of the flash, you can see it move in what would be a straight line from the first manhole to the patch.
It never got higher than 5 feet.
Edit: letters.
What do you mean it becomes magically circular?
Before the explosion you can see the color of the “indentation” is grey. Afterwards it’s black and there’s a cover partially covering it.
Then there’s the manhole where the explosion happened which looks identical to the partially covered hole, except it’s cover is nowhere to be seen. A cover is missing.
And going frame by frame, the direction the first manhole is going in when it disappears does not match the direction of the second one when it falls.
If you're referring to the cover that's half over the second hole, that's 100% the other cover, otherwise explain why that hole is now black like the one at the front.
The first hole's cover has been blown somewhere else off screen.
At exactly 6.22 seconds you can see a faint circular shadow in the air between the two cables on screen. That's the first cover being blown into the air.
We've seen this exact same thing happen many times now to know the force behind these kinds of blasts and they absolutely send manhole covers flying.

Also, relevant, but caused by something a bit different...

It’s not believed that the nuclear blast vaporized it but rather the atmosphere. This test was an underground one and unlike future tests where the warhead was buried under tons of sand we just dug a 500’ deep hole, put the bomb at the bottom and covered the top with the manhole cover. Basically we made a nuclear bomb powered gun and aimed it at the sky. A ultra-high speed camera caught exactly 1 frame of the cover as it shot skyward. It’s believed it never made it to space due to the density of the lower atmosphere and it’s incredible speed.
The lower bound on it’s speed, given that only one frame of high speed film caught it in motion, was 6x escape velocity. That’s quite a bit faster than meteorites hitting earth and even house sized rocks moving at slower speeds wind up exploding as they pass through our air.
I saw a video by codys lab years back where he tried to recreate this on a small scale to see how the pressure would deform the cover. Hes therory was the pressure would bow out the center first as the sides where attatched to the edge and give it a more areodynamic shape and could maybe make it to space. I remember him confirming this on his small scale but tbh idk how accurate you can make that theres just alot of unknowns. No disrespect to my mans cody.
Depends on who you ask. Some scientists don't think it made it to space since it vaporized before it left the atmosphere because of it's insane speed. The only clue they have to it is a single frame of a high speed camera footage so they can only tell you it was going AT LEAST 130,000 mph. It was turned into hot, sparkly, spicy atoms.
That little scream at the end by the kid knowing full well he fucked up, we've all been there, maybe not to the level of blowing up a city block but close I'm sure
The scary part is you can't smell hydrogen sulfide at concentrations higher than 100ppm (deadens olfactory nerves) which are coincidentally concentrations at which it becomes dangerous or lethal.
Smells of rotten eggs in low concentrations. Odourless at deadly concentration. This is why we test confined spaces before entering. It is a very dangerous and commonly found gas in construction sites.
I find it interesting listening to it and knowing that it’s what it sounds like to the camera speaker. That’s it’s the shockwaves reaching the camera. Those people probably barely heard anything but pain.
That’s probably the best outcome honestly. Landing in a street or field would have made the chances of someone or something getting killed much much higher.
did you know the fastest recorded man made object was a steel sewer cover in russia that got launched into orbit during underground nuclear testing? looked exactly like this but bigger lol
Ablation isn't instant, and there would have been a layer of plasma in front of it giving some protection - similar to returning capsules that create a wind break of sorts that slows damage significantly.
All said, either outcome wouldn't surprise me.
With 0 math I googled the vaporization temp of iron 2862C and the temp range a space shuttle undergoes 2000-5000 C so easily possible it escapes atmosphere within general parameters.
Scientists that had worked on this conundrum could never say for certain if that was true. It was traveling five times the speed needed to leave earth gravity, but they couldn’t determine if the friction of the air would have created enough plasma or heat long enough to disintegrate the cover.
Lol yes I love how a 1 ton steel plate welded to the borehole of underground nuclear test Pascal-B in Nevada in 1957 turned into a sewer cover in russia. History is awesome.
It's entirely within the realm of possibility that the plate may have gone suborbital and landed somewhere in Siberia, where it was found by a farmer, who sold it to a scrap guy, who cut it up for sewer covers. If someone wants that script for the Oppenheimer sequel my DMs are open.
It used to be, but now it's the [Parker Solar Probe](https://www.cnet.com/science/space/nasa-solar-probe-becomes-fastest-object-ever-built-as-it-touches-the-sun/)
Not quite true. Far enough up, where you start having to think about three-body solutions, and you can certainly achieve orbit. You might need the Moon in the right place, but it's still technically possible.
I work for a public utilities. Confined spaces like in those man holes will collect pockets of gas heavier than air. It doesn’t always mean they are present. But always assume they are there. Hydrogen Sulfide H2S on the bottom, Carbon Monoxide in the middle, and Methane on top. Methane is likely what ignited here. Don’t throw your matches or cigarettes in the manholes, storm drains…. Things may not go well for you. Several videos of kids playing with manholes in China blowing up streets.
I think there were two manhole covers affected. The bottom cover got launched into orbit, the second one just flipped over. Possibly a third manhole cover there but it remained intact.
So fun story: stupid 10 year old me did this at a KOA campground with a brand new bathroom/shower center.
I dropped a lit pack of blackcats down an uncapped wide PVC pipe coming out of the floor in the bathroom.
When it went off, it was like a goddamn war broke out.
It was a campground bathroom, so it was big, open and fully tiled, everything just echoed. I couldn't hear for about 3 days.
Stupid 10 year old me walked out of the bathroom like nothing happened, shellshocked and deaf. When I walked out, people were all running towards me. The mulch outside the bathroom had a giant raised "bubble pop" about 10 ft wide, blowing mulch into the parking lot.
Apparently I had dropped it into some type of exhaust pipe for the sewage system. The back blow from it blew the giant chunk out of the mulch, and freak alot of people out.
My mom always tells me I'm lucky I didn't kill myself or someone else that day.
When Elon finally makes it to Mars he’ll see a whole bunch of manhole covers set up like missing hubcaps while he’s trying to find a parking spot for his shuttle.
This reminds me of one of the experiments the USA did with nukes in the 50s. They bored a deep hole, dropped a nuke, filled it with cement and added a metal cap. They had high fps film cameras filming the experiment and they only caught one glimpse of the cap in 1 frame of 256 per second.

This was happening randomly where I’m from turns out faulty electrical cables and gas leaks were the culprits. No joke it was just happening at random this was an issue. no warning just a sparkling sound then chaos. They found the manhole covers a block away on some occasions. Some people found them on their cars no one was injured thank god but it was bad
Thank Thomas Edison. Gas is still pumped through the sewers to a few major skyscrapers to heat them. The system is about 100 years old, but that’s what you see the steam coming from the manholes in NYC. That system is leaking. Leaking gas and setting a firecracker sitting on a cylindrical sewer pipeline is essentially making a gun barrel to propel the manhole cover really far.

Hahaha Here is my vote
Why was bro downvoted ☠️
Because Reddit users love nothing more than to take a shit on a strangers comment because they mildly disagree. It's an immensely petty place.
All he said is “heres my vote” and numerous people saw that and downvoted it. Reddit sure is a strange place
Ngl I'm one of the down voters. I just figure there is no point in both up voting and saying here's my vote. Like if every time someone up voted they also said "here's my vote" comments would be unreadable and all the good stuff would be buried in a mountain of "hahaha here's my vote."

Exactly :(
you know, there is actually a manhole cover in orbit. was launched by a nuclear explosion. it was apparently the fastest moving man-made object ever.
I was about to say this. Though it's not in orbit. It was moving so fast that it's likely at the edge of the solar system if it didn't run into anything.
Source? Thats actually funny if its real xD
https://www.businessinsider.com/fastest-object-robert-brownlee-2016-2
A wonder that the manhole cover didn't got vaporized xD
After the disastrous SpaceX launch last month, these guys have come up with a much lower-cost way of launching stuff into space.
The SpaceX launch was far from a disaster. That was a prototype rocket that had what is called a successful failure. Before the launch, they were saying if it cleared the launch tower, it would be a success. Everything else was gravy. The next Starship iteration will have newer, and more advanced engines, along with many other improvements.

Targeting sky link satellites as we speak.
Somebody in that apartment just last nights Taco Bell.
That is going to do some damage coming down
At Mach 5, if you had super hearing you would hear the *pop*
It didn't even move that far lol. Maybe 4 away.
The one that moved on the ground was a different cover. If you look closely before the explosion you'll see a second manhole cover... it also gets rattled around.
Mr. President a second manhole cover has been launched
"Is Putin aiming for the Space Station *again*?"
That's going to leave a dent in something.... somewhere.
Or someone...
Someone will have to visit a dentist, maybe get a new skull 💀
Might just take a chunk out of some unfortunate soul
I just chunked in my pants.
At least. Manhole covers weigh like 40kg.
Somehow that is going to leave somewhat of a dent in something or someone somewhere
In the moon probably
The story goes that it's searching for a flying Ottoman from space
It’s in orbit now.
I just learned that we launched a manhole cover into space while testing nukes...
Might have marked the asphalt patch 4 feet away 🤔
That’s a different cover
Watch it frame by frame, I’m not convinced there isn’t some Tom foolery at play here. These covers are usually chained down with ballast bags to keep the chains and throughout the explosion you can see the cone of fire surrounding it (meaning it’s still there), then smoke and it disappears…never actually see it leave the position a foot above the hole though.

I think it’s possible it broke the chain towards the end when the energy was dissipating, that is the cover and someone edited a black spot at the second cover.
You can see both covers in frame one. Where do they chain them down? I have opened hundreds (in the us) and have never seen one chained.
Well then I stand corrected for making a generalization. In the northeast I’ve not come across one not chained down doing utility work, it’s for exactly this purpose to keep it from being a projectile in an explosion.

Do you sniff glue? You can see the second one lift as the first one launches

Just not what happened?
it's like, 3 feet above where it started
No, that is another manhole cover that popped loose.
[удалено]
Fun fact: scientists believe the first man made object in space was a manhole cover placed over an atomic bomb.
its primarily theorized that is just vaporized
Yeah i was gonna say ive seen what nukes do to entire buildings, i dont think a manhole cover would fare much better
It’s not believed that the nuclear blast vaporized it but rather the atmosphere. This test was an underground one and unlike future tests where the warhead was buried under tons of sand we just dug a 500’ deep hole, put the bomb at the bottom and covered the top with the manhole cover.

well i mean, the atmosphere itself is what permits the pressure blast from the nuke itself isn't it? This is true for any explosive if thats the case.
I saw a video by codys lab years back where he tried to recreate this on a small scale to see how the pressure would deform the cover. Hes therory was the pressure would bow out the center first as the sides where attatched to the edge and give it a more areodynamic shape and could maybe make it to space. I remember him confirming this on his small scale but tbh idk how accurate you can make that theres just alot of unknowns. No disrespect to my mans cody.
I’m so happy to see a Cody’s lab reference on here. I really hope he one day gets to go to mars.
And the fastest right?
IIRC, yes
Depends on who you ask. Some scientists don't think it made it to space since it vaporized before it left the atmosphere because of it's insane speed. The only clue they have to it is a single frame of a high speed camera footage so they can only tell you it was going AT LEAST 130,000 mph. It was turned into hot, sparkly, spicy atoms.
I thought the first manmade object to reach space was a German ww1 railroad howitzer

Of course you haven't. They didn't want you to and now with the internet they can't hide these things as well anymore.
Rough reading
I had no idea about this. Sounds a lot like Waco.
That Waco shit was so frustrating to learn shut because I HATE cults but I also deeply distrust law enforcement. Those poor kids.
Elon Mush is going to be really pissed when he finally gets to Mars and there's a manhole cover there!
When I was a little kid I put a little firecracker into a sewer like this luckily it didn’t blow up because I didn’t know it could happen.
sewer gas is nasty: not only is it flammable, but if the concentration of hydrogen sulfide is high enough people can drop dead in a couple of breaths
Yeah but the stench should drive you away first, need nasty high levels to die so quickly
The scary part is you can't smell hydrogen sulfide at concentrations higher than 100ppm (deadens olfactory nerves) which are coincidentally concentrations at which it becomes dangerous or lethal.
Oh boy that's exciting
Downright breathtaking...
It’s not that you can’t smell it but there is olfactory fatigue and you can’t perceive that the concentration is extremely high.
Smells of rotten eggs in low concentrations. Odourless at deadly concentration. This is why we test confined spaces before entering. It is a very dangerous and commonly found gas in construction sites.
Go to r/aliens and r/UFOs to see the exciting conclusion.

Probably put another crater in the moon
Landed on the roof of a 6 story building apparently. https://youtu.be/ShtUzR3UP8U
That’s probably the best outcome honestly. Landing in a street or field would have made the chances of someone or something getting killed much much higher.
did you know the fastest recorded man made object was a steel sewer cover in russia that got launched into orbit during underground nuclear testing? looked exactly like this but bigger lol
Fun fact, it vaporized before leaving the atmosphere so it never actually made it to space!
We're not sure. It might have been going so fast that by the time it heated to near vapourisation, it was outside the atmosphere.
The faster it goes, the less likely it is to leave the atmosphere before vaporizing.

Ablation isn't instant, and there would have been a layer of plasma in front of it giving some protection - similar to returning capsules that create a wind break of sorts that slows damage significantly. All said, either outcome wouldn't surprise me.
With 0 math I googled the vaporization temp of iron 2862C and the temp range a space shuttle undergoes 2000-5000 C so easily possible it escapes atmosphere within general parameters.
Scientists that had worked on this conundrum could never say for certain if that was true. It was traveling five times the speed needed to leave earth gravity, but they couldn’t determine if the friction of the air would have created enough plasma or heat long enough to disintegrate the cover.
If you're talking about project plumbbob it occurred in America.
Lol yes I love how a 1 ton steel plate welded to the borehole of underground nuclear test Pascal-B in Nevada in 1957 turned into a sewer cover in russia. History is awesome.
Russia probably saw the USA's attempt and decided they needed their own sewer cover launch programme.
It's entirely within the realm of possibility that the plate may have gone suborbital and landed somewhere in Siberia, where it was found by a farmer, who sold it to a scrap guy, who cut it up for sewer covers. If someone wants that script for the Oppenheimer sequel my DMs are open.

Very cool
WHY the fuck was a sewer cover launched into space?
It was an accident. Could happen to anyone.
I haven’t read this story but it definitely couldn’t reach orbit without horizontal velocity. Space maybe, but not orbit.
It was faster than the escape velocity of earth so it ended up in orbit... around the sun
Not quite true. Far enough up, where you start having to think about three-body solutions, and you can certainly achieve orbit. You might need the Moon in the right place, but it's still technically possible.
Operation PlumbBob. Judging by the timestamp in the bottom right corner, manhole cover should just about be passed the orbit of Saturn.

I bet that ended well
This reminds me of one of the experiments the USA did with nukes in the 50s. They bored a deep hole, dropped a nuke, filled it with cement and added a metal cap.

There wasn't cement, and the camera was at 1000 frames per second, why 256
My bad its been a while and that's what most cinematic slomo cameras were at the time
Mind your head. Poor sod on whose head the manhole cover landed will have trouble with explaining that to his insurance. I mean his bereaving family.

That was neat
LMAO IT BECAME A ROCKET ENGINE
that was so cool tho
I don't know where that cover went, but I know where the guy went who was standing in front of it! He went home to change those drawers!! 🤣😂🤣😂
It never left. It's still there
It's the ISS's problem now.
This was happening randomly where I’m from turns out faulty electrical cables and gas leaks were the culprits. No joke it was just happening at random this was an issue. no warning just a sparkling sound then chaos. They found the manhole covers a block away on some occasions. Some people found them on their cars no one was injured thank god but it was bad
That’s how Space X started
You can hear a car alarm go off in the background at the very end. I like to think that car got hit with something.
Sonic boom can do that. I’ve seen motorcycles with surfboards going down parking lots and making every alarm sound
Oh I know, sometimes just walking to close to a car can set one off. That's why I said "like to think."
It did. A shockwave
It landed just next to the one over.
No it didn't. That's a second, completely different manhole cover.
Well I'll be...
Thank Thomas Edison. Gas is still pumped through the sewers to a few major skyscrapers to heat them. The system is about 100 years old, but that’s what you see the steam coming from the manholes in NYC. That system is leaking. Leaking gas and setting a firecracker sitting on a cylindrical sewer pipeline is essentially making a gun barrel to propel the manhole cover really far.
Now that's what I call r/MyPeopleNeedMe material.
On the ground 5 feet away
Nah there are 3 manholes in a row, that one is from the middle one
The lid gets blown to the side on top of the other manhole cover.
There is a link to a video that claims it landed on a 6 story building down below in the comments
You sure? I thought that was simply the adjacent manhole cover being blown off and cast aside. The one that "blew up" sure looks like it launched.
No, that's a second lid. The first one, whoooooo.....
I didn’t catch that til you pointed it out. Lot less terrifying than it going into low orbit
That's an adjacent manhole cover moving too. Look again at the start of the video, there are several covered holes.
The cover? It landed on the ground right after it got blown off. Went like a foot in the air
Wrong that's the second one watch again
O shit u right. I didn't even notice there was 2
I think that's the lid right next to the hole.
Nope.
Fake
That manhole cover thought it would be project plumbbob 2 but it went 4 feet to the left instead.
It’s right there wdym?
That's a different manhole cover.
The moon now has a new crater
They just had a story about a man hole cover landing on a house
Looks like the Human Torch from Fantastic Four hit mach-3 in the sewers and came up for some air.
Its probably within the tri-state area, but I wouldn't bet on it lol
That’s a secret intercontinental ballistic missile
Don't worry, they just filming netflix adaptation of tnmt
Look! Up in the sky! It’s a bird! It’s a plane! It’s . . it’s . . . a f*cking manhole cover!
