For all wondering why water vapor/mist formed in the cabin: Shown here is a rapid depressurization. As the pressure falls, the air expands, which lowers the air temperature. As you know, water vapor (humidity) is found in the air normally. If the temperature of the air falls below the dew point (varies based on humidity and pressure), the water vapor condenses out of the air and forms a mist. Great video!
I'll explain for the people who read this the next few minutes/hours: 1. you're only seeing super recent comments because the creator set the default comment sort order to "Newest first" instead of "Top comments" 2. the fog is the moisture in the air condensing into tiny water droplets as a result of the sudden drop in temperature caused by quickly lowering the pressure (a phenomenon known as "adiabatic decompression")
It's also why we can't pump water through a pipe above certain height, 33ft? because water will turn into steam in the pipe eventually while going up, with colder water you might get a bit more height but it's futile to the point we need a water pump ever 30 ft up to pump water any higher...😂
@@RSAgility not really, the reason is because of the atmospheric pressure became equal to the force of the water column, no boiling water inside the pump :)
@@RSAgility ehh, that's not really a related phenomenon at all... Also, you can pump water upwards just fine as long as you put the pump at the bottom, not at the top, i.e. you can push the water up but not pull it up. The pressure required will however quickly get very large, so it'll usually be more sensible to use multiple smaller pumps along the way.
When fighter pilots intercept unresponsive planes, foggy windows is a telltale sign that the plane depressurized. At that point it’s just a ghost plane flying on its own.
I was on 93S heading into Logan, my Brother texts me, where are you? My Brother was on a flight to Boston and the plane depressurized. Masks fell down, Stewardesses screaming to put the masks on while the Captain and Crew of the jet had an emergency descent. Arrived on the ground and he said you have no idea how comforting it is when you see an airport's first responders/ fire trucks/ ambulances meeting you and chasing the jet as you hit the runway. Pilot knew his shit and saved countless lives that day. I will always be forever grateful to the Pilots and Crews of US Air.
@@ernesthill4017 ahhh shut up. You don't know for sure that every person on the flight would have died. Maybe just a few would have died. Due to the pilot's quick thinking we'll never know. You'll never be able to count the amount of people the pilot saved that day had the situation been worse. Hence it's countless.
@@lesismore7478 but there would have been a maximum number of lives able to be saved. They couldn't have saved more than the amount of people on the plane. Therefore it was not countless.
I’ve always been afraid of airplane depressurization, despite the MythBusters having proven twice over that it is extremely difficult for an airplane cabin to decompress. Now I know what to look for on my next flight.

Due to that event all aircraft, in order to maintain Airworthy certification, had to have detailed inspections for what are called scribe lines on the outermost skin of the aircraft.

My husband was on United flight520 May 27 2018 on the 11:35 am flight from New Orleans to Houston and this happened at the end of his scary flight! They took off got to cruising altitude of 239000 feet and within a few minutes the oxygen masks dropped. Captain came on radio and said were loosing oxygen and depressurizing this is not a malfunction,everybody put on the masks and buckle up ASAP! He then said we have to drop below 10k feet to get to safe oxygen levels and we have to do it quick so buckle up!They made the nosedive down from altitude of 23900 to 9900 in 6 minutes. He said he heard the Stuart’s say they had a leak and loosing pressure. The whole time no cool ac and he said everybody including him was having a really bad time with the pressure on ears. When they finally landed and stopped sirens started going off and the pressure got so bad he said it was hard to breathe, felt like throat was closing he said. Everybody’s hands covered ears and their heads went down between their knees. Pressure was so bad he couldn’t hear himself speak, couldn’t hear the person a foot away speak. Kinda like a silence. Then the cabin filled up with this smoke/steam/fog. He says everybody thought plane was on fire. Then the captain comes over radio and says the doors are not opening because of the pressure. After about ten minutes they finally open. He was supposed to get on an international flight to Trinidad/port of Spain and he cancelled his trip because of the ordeal. Said it was scary as hell!
I've always been afraid of flying. I've only been on a plane 4 times, over the span of a few years. The last time I flew, was slightly better. I wasn't as afraid. I wanted to take a trip to California this summer, but this story is making me change my mind.
@@LittleHello427 Your chances of dying in a plane crash is 1 in 60 million. And before I ever flew that's what I was saying. But now I have flown I love planes and aviation. I hope you'll love it too!
Though the skin of the fuselage, when pressurized, slightly flexes. Outside the aircraft, people were on all manor of elevated work platforms, inspecting every square inch of the cladded aluminum and installed rivets. Recently the company I work for has partnered with a specialized drone company that has a $250,000 inspection drone with a neural learning Artificial Intelligence. It can do in one hour what it takes a team of people ten hours to do.
The pressure in the cabin is lowering so the air inside is allowed to expand, which causes it to cool off. When the plane depressurizes, the temperature is suddenly low enough for the water to return to the liquid state from gas. The water forms small droplets that clump around dust in the air, which are big enough to see. What you're essentially looking at is fog forming in the airplane. Pretty cool.
That is the coolest looking form of death ever. Just getting enveloped by a cloud, and silently passing out, then… nothing. If I died, I’d rather go quickly or in my sleep, but if I didn’t have a choice, this would be it.
If it's possibly my last few seconds I'm so totally pulling out the joint I hid. On a related note the TSA these days are largely incompetent temp hires that are easy to dupe. Not saying how exactly but they aren't sending their best and the terrorists will still probably succeed again eventually...just in time for you to lose more rights liberty and freedom in the subsequent passed laws.

No, you are wrong. Air can hold MORE water vapor at a lower pressure. The actual reason the water vapor condenses is that lowering the pressure causes the air temperature to drop faster than the dew point.
@@mistrzdemograficzny4218 Indeed. Although I would say that it's better not to use the word "hold" at all because it causes misconceptions and is not what's happening anyway. Water vapor can exist with zero air, so air doesn't need to "hold" anything.

It’s amazing to see the water hit its dew point in real timer. If you want to understand what’s going on here think about when you spray a can of deodorant and the can of deodorant starts to get cold, well that’s what’s going on here. The pressure wanting to reach equilibrium with the air pressure outside the plane and the drop in pressure as the air rushes out of the cabin causes the cabin to rapidly cool and the water in the atmosphere hits its dew point and that’s what your seeing.
Very interesting demonstration. It's something were told about but hopefully do not get to witness. A barometer in the shot would be interesting to watch how quickly and how low the pressure gets.

before the like beggars come in to proclaim the YT algorithn has brought us together, and that "fun fact: you did not search for this", i did. i deliberately searched "airplane cabin depressurization" for my studies, thank you for your time
Looks like an MD-80. You can really dump the pressure fast on those. I’ve pressurized lots of 737s and brought the pressure down quickly but never fast enough to do this.
This is probably what a slow decompression would look like. By definition...a slow decompression takes more than 10 seconds to lose pressurization. A Rapid Dempression is under 10 seconds. An Explosive Decompression is less than 1 second with a 10 psi differential between cabin and cruise altitude. The slow deompression is more dangerous of the 3. Read on the Helios and Payne Stewart Lear accidents. I have personally been through probably 1000 decompressions vis research and training as a Physiologist in the USAF and FAA altiude chambers.
I long ago did a computer simulation of how long pressure equalization takes for a widebody at cruise altitude which loses a cabin window and then dives at I forget what angle. It was about thirty seconds until the internal/external pressures matched for the scenario I modeled. An interesting aspect is how flow at the window hole starts out as something called "choked": It can't get above sonic because that would require the proverbial convergent/divergent section like in a sold-propellant rocket motor. With just a simple hole in a flat surface, the flow gets to sonic but has to stay there. Then of course as the pressure differential drops it drops below sonic.
and I'll never figure out how this video went viral in the first place, I did it for fun with no intent to even have a CZcams channel, I only wanted to share it with friends at work. but I'm happy it did though. thanks for your comment!
Nothing too exciting about rapid depressurization, no large amounts of loose paper and debris flying around the cabin. No lights flickering on and off. The clouds forming inside the cabin is a pretty cool touch though. Hollywood will never show what true rapid depressurization looks like because it's fairly boring. Unless a sizable hole is blown out of the fuselage, having rapid depressurization is not much to look at. Great video
It depends because this plane was in the ground, keep in mind that if this Was being done at 30,000 feet in the air, it would have looked a lot different if there was a hole in the window. So is not that Hollywood gets it wrong, it’s that there’s a time and place where that exact outcome can happen.. but not in the ground while there is no damage to the hall
actually, we were conducting a fuselage leak check from the outside of the craft. we had to pressurize the aircraft many times to see if our repairs were functional.
I've clearly beeen watching too many movies because I was bracing myself for a massive explosion sound followed by a mini hurricane inside the fuselage
Amazing how calm those passengers were.
It’s almost as if they didn’t exist!

Whoops their all dead or disappeared in a cloud of smoke
(I know its not smoke, its humidity)
This must be the pilots first day. Putting the clouds on the inside of the plane instead of the outside is a rookie mistake.

it usually does not happen on your first day, depressurizations happen to every pilot not (sometimes on their first day).

For the record oxygen masks would have been deployed had this been real and functioning properly
That's why we pull the circuit breakers for the emergency Equipment and when we do have to test the equipment we pin the oxygen generators because they are single use and generate a lot of heat
I was actually waiting for them to drop
@@Terkinstein what are the oxygen makers made of?

@@Terkinstein soon as you said it creates a lot of heat I knew it was a chemical reaction of some sort so that makes sense thanks!

CZcams algorithm: Rapid cabin depressurization
I'll see you again in 2029
So this has been randomly recommended to everyone lately?
Yes, it seems. It randomly appeared on the page.
Yep, even the non-avgeeks apparently
before the like beggars come in to proclaim the YT algorithn has brought us together, and that "fun fact: you did not search for this", i did. i deliberately searched "airplane cabin depressurization" for my studies, thank you for your time
Legit
The YT algorithn has brought us together, and you did not search for this.

CZcams algorithm is strange. Why this video was recommended to me and clearly many others is a mystery...
maybe I hacked the algo? lolz
Like any other place on earth, the plane has its own ecosystem and ever-changing climate.
Looks like a case of global cooling to me.
Not water vapor; it's all the farts that have been pushed into the seat cushions. 😮
It is water vapour. When the cabin pressure drops the air can't hold on to the water.

Gotta love the algorithm for putting this in our recommended almost a decade later, lol

Why is everyone getting this recommended this all of a sudden lol
DON'T GET ON THAT PLANE! - The Universe, probably
The algorithm wants to tell us something really important
or its just broken again
Maybe we all booked a flight with a Boeing ?
The algorithm has spoken
"how was your flight?"
"Yeaahhh mann it was great man, how was your flight???"
I watched the video thinking something would explode, but I ended up flying in the clouds instead.
Anyone else noticing how the sound is much lower after the depressurization, you hear alot less noise... very epic how air pressure works
Least dangerous Boeing flight
Boeing aircraft have carried more passengers safely to their destinations than literally any other aircraft, but go off, bro.

@@tapiocamangoyeah
@@codyking4848Maybe you should read the news, buddy.
i see the algorithm has brought us all together again
indeed
Looks like an MD-80. You can really dump the pressure fast on those. I’ve pressurized lots of 737s and brought the pressure down quickly but never fast enough to do this.
did everyone get this video in a span of 1 day lmao
yar
YT does that sometimes. actually quite often
YT warning all of us of Boeing lol
Yo buddy,this is a md-83 not boeing.
Damn 40 likes an none know what a Boeing plane is bet u be flying them without knowing
Boeing is guilty of a lot of things, but this can happen to ANY plane. please use your noggin
CZcams 8 years after it got uploaded: guys you HAVE to see this!!!
This is probably what a slow decompression would look like. By definition...a slow decompression takes more than 10 seconds to lose pressurization. A Rapid Dempression is under 10 seconds. An Explosive Decompression is less than 1 second with a 10 psi differential between cabin and cruise altitude. The slow deompression is more dangerous of the 3. Read on the Helios and Payne Stewart Lear accidents. I have personally been through probably 1000 decompressions vis research and training as a Physiologist in the USAF and FAA altiude chambers.
How is slow more dangerous?
@@twistedpickle6984 It sneaks up on you
I long ago did a computer simulation of how long pressure equalization takes for a widebody at cruise altitude which loses a cabin window and then dives at I forget what angle. It was about thirty seconds until the internal/external pressures matched for the scenario I modeled.
An interesting aspect is how flow at the window hole starts out as something called "choked": It can't get above sonic because that would require the proverbial convergent/divergent section like in a sold-propellant rocket motor. With just a simple hole in a flat surface, the flow gets to sonic but has to stay there. Then of course as the pressure differential drops it drops below sonic.
The only thing this proves is that camera man will survive anything

Man the Engineering in planes never fails to impress me💯🚀
CZcams recommended this video to us just 8 years later
Thank you youtube algorithm for recommending me this absolute banger of a video
That air looks so tasty and refreshing
Hmm, tasty.
Yeah wait till you get a wif and wake up with your legs tied like a pretzel
I was expecting it to suddenly depressurize like a flashbang or something.
How the hell did I find a comment that was made less than an hour ago on an 8 YEAR OLD VIDEO???
and I'll never figure out how this video went viral in the first place, I did it for fun with no intent to even have a CZcams channel, I only wanted to share it with friends at work. but I'm happy it did though. thanks for your comment!
@@Terkinsteinand the video maker responded as well😂
Me bro😂
@@bamber7712😂😂😂😂😂
Nothing too exciting about rapid depressurization, no large amounts of loose paper and debris flying around the cabin. No lights flickering on and off. The clouds forming inside the cabin is a pretty cool touch though. Hollywood will never show what true rapid depressurization looks like because it's fairly boring. Unless a sizable hole is blown out of the fuselage, having rapid depressurization is not much to look at. Great video
It depends because this plane was in the ground, keep in mind that if this Was being done at 30,000 feet in the air, it would have looked a lot different if there was a hole in the window. So is not that Hollywood gets it wrong, it’s that there’s a time and place where that exact outcome can happen.. but not in the ground while there is no damage to the hall
@@MichaelOrtega youre right, this just looked like a visual demo of how the system works (if its used in that setting).
actually, we were conducting a fuselage leak check from the outside of the craft. we had to pressurize the aircraft many times to see if our repairs were functional.
I've clearly beeen watching too many movies because I was bracing myself for a massive explosion sound followed by a mini hurricane inside the fuselage
Me too! LOL
