Operation Plumbbob was a series of underground nuclear tests in 1957. In one of the detonations, a steel bore-hole cover went missing. When they watched the film back, it could be seen being launched, at great speed, into the air. So, it wasn't really a "manhole cover".
so it was moving that fast in atmosphere? wow
@@hzhang1228 It was only visible in 1 frame and they used the distance it traveled in that 1 from to estimate its velocity. Most think that it probably vaporized in the atmosphere shortly after detonation due to frictional heating.
@@codytank111 I thought it flew out of the atmosphere so quick it didn't have time to burn and technically was the first object launched into space before sputnik.
@@shrekjuniorv2561second, though some think it didn't go that far, first was MW 18014, a german rocket they vertical tested in 1944 and reached outer space (higher than they planned for it go)
There was a plane but in 1965 I believe that managed to go in space for a short time
"I heard the space station." Thanks for the laugh Dave.
The manhole cover was a nuclear test where they hilariously thought capping a hole where they were going to test a nuke would do anything. They estimate that if the metal cap didn't get vaporized it would have been shot into space at about 150,000 mph.
Edit: Operation Plumbbob
It's a huge allegedly because that's according to the "primitive" video capture equipment back in the day and the fact we can't/won't redo the test today with our better equipment. So all we can do is speculate what it could have done based on what has been presented. I'm not saying it didn't, but I can't confidently say it did either. It's like trying to say that Pheidippides ran exactly 26.2188 miles or 42.195 km exactly and neither an inch nor a centimeter further or shorter to exactly establish the modern marathon. I mean based on what we can glean, sure he ran that distance..... but was it that exact? Who's to say besides him. Did the containment cap of Operation Plumbbob really go that fast? I can't say, but math and physics would dictate that it went the scientific speed of a lot of "Pretty f**king quick"'s per second.
But I think the more bonkers idea was up until then we all knew what explosions did. We all knew how explosive ballistics worked, and yet they thought that some how "containing" a massive explosion would not result in either a different bomb or cannon like scenario and were genuinely surprised when it happened.
@@steeljawXwith all the thing they definitely lie about who cates just enjoy the thought of it 🤣😊
Dave, you can't hear the space station. It's in space, no air, no sound. You didn't see it either. Did you say you had just left the pub? 🤣
He for sure didn't hear it. However, the ISS is visible at times.
You absolutely can see it. There's even a website that tells you where and what time's it will be visible. I've seen it half a dozen times myself
@@tacoma1219 I'm aware, I'm just saying Dave didn't see it, he was probably looking at hot air balloon.
@@1980bcman Dave didn't see it though. The space station isn't something you just randomly notice while stumbling out of a pub.
Also, not going to hear it before you see it at the speed it is moving. Dave talking shite again LoL
The Thrust SCC did go above the speed of sound, the only land vehicle to do so. Also you wouldn't hear the ISS, because it makes no sound due to lack of atmosphere in space, Probably a plane flying by at the same time (or you were a little too drunk)🍺😉
I think they mistook and swapped the top right portion talking about the speed of sound for what the display of the sound was. That's my logic for the misunderstanding lol.
Thrust made a sonic boom in ‘97 in Black Rock Desert, Nevada, USA. The resultant sonic boom caused sprinkler covers to fall off in the town of Gerlach, around 10 mi (16 km) away.
The first man made object to break the sound barrier was.... The bullwhip.
well, yea
What’s even crazier is 66 years after the first air flight, we landed on the moon.
LOL You didn't hear the ISS. It's in space there is no air to transmit sound.
Airplanes make a hell of a racket and that's just like 10-12km, no chance with the ISS at 400km which doesn't have huge loud engines.
Probably simultaneous plane noise that got them to luck up.
Ahhh those good ole fashioned man made cheetahs..
Great video, bad title lol And Dave, you cannot hear the International Space Station. It doesn't make any noise. Idk what you heard, but it wasn't that. It also stays in a steady orbit so it wasn't "at it lowest point". You can't even hear a plane at cruising altitude from the ground lol
Wait, you've never visited your local cheetah manufacturing plant?🤣
I was going to make the same comment about the ISS, but I'm glad to see others a beat me to it. Yeah, orbiting at an altitude of 250 miles you're not going to hear it at all.
@@jusblazed1ful You wouldn't hear it if you were right next to it on a space walk haha
If you read the text by the Cheetah it said (reference)
Well, in May 23 2000, the ISS actually was at it's lowest point. It dropped to 207 miles, I'm not saying Dave heard it. He definitely didn't. But he's 100% right that there was a time when the ISS was in danger and needed to be boosted.
Parker Solar Probe is crazy. It's going like 1/2000th the speed of light. Its clock is already several seconds slower than ours due to relativity over the course of its life so far. At least doing hand-wavy math.
People always talk about the Voyager probes speed and neglect the Parker Solar Probe being insanely fast.
@@Timmycoo I guess there's some attraction to the Voyager probes heading out on unbound trajectories, while Parker orbits the Sun. Like it's a track speed.
@@dudermcdudeface3674 Yeah I assume the same. Not as much of a selling point to orbit the sun as it is to break away from the solar system.
5:54 Thrust SSC was developed to break the sound barrier on land. That was its purpose. It's a rocket propelled vehicle.
Actually jet propelled.
The fact that the Wright Brothers plane is not that (relatively) long ago and we've come this far is pretty insane to think about. The technology age really develops fast. I can remember the 90s feeling like they were just a little while ago but seeing tech from back then feels super out dated.
Kinda surprised not to see the Concord on this vid. I do like me some RED SIDE vids.
The X43 is an experimental, scramjet powered hypersonic missile that's been in development with the USAF as a delivery method for bombs or for getting small satellites into orbit. Not a full production vehicle as of yet in the US...
Dave! You are our UFO guy! I do agree though. They developed the SR 71 Blackbird in the 60's and that NASA jet in the 90's. Think of what they have today. I doubt we have any material that can withstand turning on a dime at those speeds though. Just a thought.
Don't assume they have anything too interesting today. Just because crazy advances were made in one time doesn't mean you can extrapolate forever. Military R&D today is really badly managed.
Except for the part about him "Hearing" the ISS. Which is literally impossible because at it's lowest point the ISS was still 207 miles up in space. Sound doesn't travel in space, only in the atmosphere. If the ISS ever travelled from space to the atmosphere it would explode into a million different pieces.
I absolutely love how they throw in the manhole cover with zero context
"I'm not a scientist"...really Dave, really?
Gotta watch out for those hypersonic manhole covers.
they set a nuke off underground and put a manhole cover above the launch site, this is it's recorded speed
I didn't know that these things went this fast!!!
Crazy how little time it took from man inventing the airplane, to man creating a space shuttle & putting a man on the moon.
"I'm not a conspiracy theorist" - every conspiracy theorist ever 😂
45km/h ”average cycling speed on flat ground” lmao
I manage 43.443km/h but I do stay in biggest chainring and smallest cassette cog even at traffic lights and accelerate away in it
Gravity and friction are the true winners.
Im laughing at the usain bolt animation 🏃♂️😂
I mean.....define "man-made" and define what qualifies as "fastest". On a technicality, things in the LHC are naturally formed but are artificially accelerated to insane speeds and the technical "man-made" collision energy would accelerate super fast from impact. Sooooooooo, how "ACKTUWALLY" do you want this to get?
That aside, you didn't comment on that knob of a cop sitting on the side of the road as the various bicycles and motor bikes passed by. . . .He's gonna pull over a historical motor vehicle for speeding......Good gravy.
To put things into perspective, voyager 2 covers 172,000km every single hour. It has been doing that for 46 years and hasn't hit anything. That's how far apart things are in space.
It's literally impossible to hear the ISS. I love ya Dave, but at it's lowest point it was still 207 miles above Earth. It was still in space, sound doesn't travel in space. Sound travels in the atmosphere. And if the ISS was ever in the atmosphere, it would be a meteoric fireball.
I wonder how perfect the surface of the "track" has to be to hit the speed of sound with a wheeled vehicle.
They do those tests at the salt flats in Utah, USA, if you're not from the states. It's the best place to test high speed land rockets!
I think there was a manhole cover that got exploded up into space, idk if it's a true story...
It's speculation but in all likelihood it evaporated post explosion and the single frame it was caught.
@@Timmycoo dang... that's wild.
Didnt you guys do this one before? UFO only means Unidentified Flying Object, does not mean, ALIENS from outer space!!
None of these are faster than my granny's Dodge Stratus
Ben Mallah Life of a $250 million family
👏👏
I thought they watched this before
What powers the satellites and the space station I thought they just floated around
It's not so much they're "powered" in their travels as much as they need power for their systems. They're quite literally yeeted in one direction and once they run out of fuel, that's it. There's no friction to slow them down and that entire time they were accelerating, they were accelerating unfettered, meaning there was almost no limit. Once they ran out of fuel, then they had no acceleration to increase their speed, but then there's really nothing slowing them down either. No air resistance, no friction (or at least negligible), they're gonna go until they get out of range, lose power, or hit something. But for their system power, they're using solar panels to recharge.
You definitely didnt hear the ISS 😂 thats not how it works
I do not recommend videos from that channel. They crept into my algorithm months ago comparing objects sizes and they goofed some of the commercial aircraft model sizes AND data shown, missing some by tens of feet, defying a simple Google search even.
They know how to make clicky content though that’s for sure.
They're not the worst, but they definitely can do a lot better. I might recommend videos from them to give people ball park ideas of comparisons, but I'd definitely note that it's a ball park, not a ruler. It gives you a sense, not an exact comparison.
Murica
Pointless and wrong. There's no concept of "speed of an object" in space.
It's relative to other objects
the 8k mph Nasa jet is a "manned vehicle" that has been tested but never been manned because they can't keep the vehicle stable when going that fast (as of a few years ago at least) so it's definitely not maneuverable at those speeds lol. the problem is it does too much unwanted maneuvering hahaha
