I know this.

The water is due to condensation and the insulation blankets not being installed correctly in the crown.

When installed correctly, the blankets lead the condensation around the cabin and to the keel, but when not installed correctly, let it pool above and eventually leak.

Additionally, this is a 787 (can tell from the windows) and are extra prone to condensation for multiple reasons.

Source: me, I work on 787s.

So, do the insulation blankets absorb condensation from the air inside, people’s breathing and sweat, like big dirty air con filters? And does that affect the weight of the plane at all? I assume it’s losing weight via fuel but when it lands at its destination is it 50% body fluids?

The blankets are waterproof so no worry about absorption.

The condensation is majority water vapor that cooled on the inside walls due to the 787 having better pressure holding abilities and higher moisture content in the cabin air for comfort.

ILikeBigThings2@reddit

It’s coming from the outside air that the 787 brings in through the scoops.

As someone else commented, it is scrubbed for moisture, but it is still moister air than you would get from engine bleed. One of the draws of the 787 is that you get better cabin air quality so you feel less jet lagged. The downside is moister air condensates more.

Well at cruise the air is dryer than the Sahara. And if they are taking in outside air, they’re also letting out inside air. So conditioned air is being replaced by dry air. That results in moisture and weight loss.

Emotional-Ad-6494@reddit

Is this a common issue or bad it was installed incorrectly?

[-]

ILikeBigThings2@reddit

Bad install.

The 787 had chronic issues with this early on and air India was an early adopter. This is most likely an old video from back then, but if not, likely poor reinstall after disturbing the blankets for another repair.

Facu474@reddit

Interesting, I was on a 787 from JAL 2 months ago and as we were descending/landing a lot of water like this fell on my head (window seat), I wonder if it was also improperly installed there too?

Details on the 2023 incident

Date and route: November 24, 2023, on flight AI169 from London Gatwick to Amritsar.
Cause: Air India attributed the leak to a rare occurrence of "condensation adjustment" inside the cabin.
Response: The cabin crew relocated passengers to vacant seats and apologized for the incident.

Other relevant information

Boeing 787 water leaks: Reports have highlighted a separate issue with some Boeing 787 aircraft, including Air India's, where leaks from potable water systems have occurred.
Potential for electrical issues: These leaks have the potential to damage electrical equipment, leading to system malfunctions.
Investigations: The FAA ordered inspections of some Boeing 787s due to reports of these potable-water-system leaks.  This is the info I had found

Thanks for your response.

So how does this actually work in real life? Does the captain notice the water leak, contact the control tower, and then the tower consults a Boeing expert who confirms it’s not a safety issue and tells the captain it’s okay to continue the flight?

Apexnanoman@reddit

Boeing didn't want to design a new plane that didn't kill people. Because it would take to long to get to market. And that would cost money.

And airlines weren't going to buy a plane nearly as easily if it required training like it was a totally new airframe.

So they cobbled the MCAS together. And Boeing test pilots ended up having issues during flight testing. So the easiest thing to do was not tell people about it.

So that's what they did. And then didn't really tell people about the existence of the system.

Not everyone is a flawless pilot. In any industry skill level varies. So making a system that will force the plane to crash when an unknown system starts activating over and over is a terrible idea. A quote

"About five minutes into the flight, having struggled to keep the plane's nose from diving further by manually pulling the yoke, the captain turned the electrical trim tab system back on in the hope that it would allow him to put the stabilizer back into neutral trim. However, in turning the trim system back on, he also reactivated the MCAS software, which reactivated nine seconds later and pushed the nose further down."

As I said .....Built in auto crash function.

Boeing just didn't care about the massive problem though. Because any other option would have cost money. And they assumed if they killed a few hundred people it wouldn't get pinned on them.

Modern corporate mindset was the cause of the. And at the end of it all Boeing was allowed to choose their own compliance monitor. Which is the type of regulatory capture that allowed them to lie and pass it off as not needing type certification training in the first place.

So I'll bet money they will slam another plane into the ground via cost cutting soon enough.

And people will come out of the woodwork and Stan for them all over again. Absolutely amazing just how eagerly people defend corporations in the US.

C'est la vie.

Yeah except Airbus didn't intentionally build a plane with an auto crash function. Then not tell anyone about it. But you could get an off switch for it if you paid extra. And if you knew the system would try and kill you and your plane load of passengers.

[-]

FrustratedPCBuild@reddit

Two possible reasons for the crash: 1. The pilot switched off both engines, which requires accessing two switches which cannot be pressed electronically or by accident, that are nowhere near anything else that would be used during takeoff 2. A sequence of about thirty highly improbable events, all happening in just the right order

Well, we have so little confidence in this airline these days, you will understand where the skepticism comes from.

No. Nothing to do with them at all.

Great when everything else has gone tits up.but as much passengers as everyone else when things are going smoothly.

I'm talking about the thousands of moving parts,the critical systems, the nuts and bolts of everything that keeps an aeroplane flying 5 miles above the earth at 600 miles an hour for 9 hours straight. Repeated thousands of times a day non stop.

And we have soooooooo few crashes.

[-]

Spiritual_Feed_4371@reddit

Yes true I see what you mean now. Things like the Hudson River landing or that flight across the Atlantic that cruised to an island where where they were flicking the runaway lights on an off for the pilots to see it (don't remember the flight name sorry but hella interesting story I read). Those are the pilots I mean.

100% tho, you could be the best pilot in the world but there's thousands of things that can go wrong and you're done.

[-]

Fit-Custard-1842@reddit

I see snags daily that could have caused catastrophe....I see many near misses and other incidents. Repeated around the world it is incredible how few air accidents there actually are.

And yes pilots are great at the human interface bit when it all goes wrong.

I don't fly often, so take this with a grain of salt:

I took an Air India flight from US to New Delhi, and it's the best flight I've ever been on, bar none. Partly, it was because both in-flight meals were Indian food, which I love, but also there were no crying babies. And I mean zero - no kids running wild, none of that bullshit. This can be more attributed to the clientele of said flights, but still, it was a very noticeable thing to this white guy. Everyone polite and well-behaved.

Sample size of one, and maybe other airlines are shittier, but I normally hate flying. To have a decent experience flying was new for me.

Agree. This can happen if condensation builds up from the Air conditioning. And as India is very hot it can happen.

I think that’s okay if someone wants to bring frozen foods with them because of various reasons

But they should be checked in

All it takes is for a malfunction to occur in the air cycle machine and environment control system and you can literally have rain inside the cabin if the water removing system fails, trapped condensation could also make it foggy or misty inside the cabin.

Brother cause you clearly didn’t look for the other comment I directed you towards. Your reply was specially about me not understanding pressurization and me answering that specific question. The water wasn’t once mentioned in your response.

“Wouldn’t be from the engines. The pressurized air gets heated a lot but goes through a bunch of air cycle machines to cool it down. Sometimes they start to freeze and ice crystals to shoot out but wouldn’t cause that much water.

The water is probably from something in the overhead bin leaking. The shitty quality and angle makes it look like it’s most of the plane.

ElectricalChaos@reddit

Water separator on the air con/pressurization system is probably fouled and is allowing water to bypass. So now you've got humid air coming pressurizing the plane and condensing on the skin of the aircraft.

Unpressurized, planes leak all the time. Once they pressurize though water isn't coming in from the exterior.

[-]

Darksirius@reddit

They should air it out like this:

MrDannyProvolone@reddit

Not necessarily. If the right atmospheric conditions are present (hot/humid) you can get a decent amount of moisture from the pack system, especially if there is a malfunction with the water separators (which I've seen).

Also, I was on a trip (as a ride on mechanic) and we saw something similar. Water dripping from the bag bins and dripping very close to passengers. The passenger(s) were a bit upset because they thought it was an issue with our plane, causing them to get wet. Understandable.

I flew a return trip (budget) using air india for part of it heathrow > delhi , and returning mumbai> Heathrow around 2012. It was an experience I will never forget, and also would not be surprised at all with this kind of shenanigans. On the plus side my 36 hour journey was very pleasant from delhi to bangkok, and i will never forget the flight attendant who suggested a whiskey coke for a scot that can't sleep while travelling (i slept for the 1st time in 2 days).

TLDR excellent flight attendants, terrible planes and questionable pilots

TurnoverMysterious64@reddit

I’ve seen people putting all sorts of weird shit in the overhead compartments. Live lobsters in a bag of water inside a box was probably the weirdest.

[-]

bustervich@reddit

It could be coming from moisture condensing in the air ducts, water coming out of the packs, or somebody’s bag in the overhead bins.

[-]

ScaldyBogBalls@reddit

Air conditioning systems may be malfunctioning or misaligned causing a buildup of condensation, which pools up and then spills into the cabin through the passenger vents when the plane changes orientation. Maybe even some encroachment of atmosphere from the exterior to the over-cabin area.

Condensate can pretty much happen anywhere fresh air is meeting a cold surface, and planes also pass through clouds dense with moisture.

[-]

SriBri@reddit

People are saying this is fake, but I just experienced this on a WestJet 787-8. I was near the back of the plane and I believe it was row... 39? During boarding a flight attendant explained to the couple sitting on the right side that they were lucky: the window seat was vacant on an otherwise full flight because it rained in that seat. She placed towels on the window seat, and left an extra with them in case they got splashed.

It happened only during takeoff shortly after the plane pitched up. The flight attendant said she thought it was related to condensation in the air circulation system, but she wasn't certain. We were leaving Calgary, and there was a slight trickle on takeoff. She said that when they fly out of (I forget which SE Asian capital) it's a full waterfall.

Interestingly when I flew back on the same flight number out of Narita, I didn't see any indication it was an issue (no towels or empty seat).

I totally believe this video could be real, and the people look calm because this may have been expected.
