This Asiana airlines Boeing 747 was on route to shanghai, unbeknown to the crew a fire had broken out in the cargo bay and within minutes had grown to engulf the aircraft. What you are about to see is what happened to this flight and how it was able to occur, to see what happens in this air crash investigation, keep watching!
Final Report: skybrary.aero/sites/default/f...
** Asiana Airlines Boeing 747-400 Passenger livery used, I was unable to find a freighter version and would not have had sufficient time to make one before the video needed to be out! The Livery would be the same just with the passenger windows covered up .

Never again watching your video, thanks to your enforced implanting of sponsorshit content.
watching this video reminds me of UPS 6, the crew followed all the checklists for a cargo fire but couldn't reach safety in time
True, another flight carrying many batteries (Not that I am blaming the batteries because it was not proven, but a coincidence at the very least.)
Ups now has these crazy devices that form a bubble around the instrument panel so the crew can see the instruments.
was nice to hear UPS going above and beyond in order to try and protect their pilots, by all accounts being unable to see their instruments made any chance of a safe landing impossible, relay planes passing on information which was slightly outdated, the final factor was the first officer being told to turn to 095 but in the smoke turned it to 195
Didn’t that flight crew turn around to their origin which was further than their destination. Because they thought landing with known procedures was the best option. Very hard to see the complete logic of that choice that doomed them.
@@CuriousPilot90would you also argue that there was poor quality control in the production of the batteries?
A very experienced flight crew for Asiana Airlines didn't seem to make much of a difference in the flight of this airplane. A truly sad situation for all those involved with this flight.
May the Pilots Rest In Peace.
I hadn’t heard of this one before-absolutely tragic for the crew but as always, you described the situation very well. Thanks again for another excellent video :-)
Thank you, this was in interesting one to research and make. Interesting but tragic.
Major resemblence of UPS flight 6
I was just writing this too! I knew of UPS flight 6 but not this one!
RIP pilots, very sad incident. Congrats on the sponsors, you deserve it!
Great video. Thank you for not trying to shorten it to 10 minutes.
I was not familiar with this tragic incident at all. Thanks so much for another thorough and well-documented presentation! Always look forward to your videos. Cheers from Canada!
Thanks Jamie! 😁
I can't think of a more lonely and tragic place to die than on the flight deck of a cargo aircraft.
Amazing quality video, your hard work shines through in your video. Absolutely devastating fire, the pilots tried their absolute best, I cannot imagine their terror during their last moments knowing there’s nothing that could be done.
Thank you! It was really chilling to script and record those last moments. A very sad and tragic moment.
I'm glad I saw the community post. I didn't get notified for this one.
Very good videos brother. Short and informative. Keep it up. I watched all your videos
Thanks 👍
Great video, excellent explanation and fantastic narration. 👌
Thanks Nigel. I appreciate it.
RIP Good Pilots.
Man, main deck fire, me: Pull the speed brake, put the fucking gear down, and MMO descent, maybe a little more! I'm going to get as close to the ground as soon as possible and if I even have to push the speed of sound to get there, I'm getting there! I don't care about the gear doors, and I'll put out the flaps just above flap speeds if I have to and even do a full slip to get this airplane down NOW!
Folks, as a 30 year airline pilot and former 747 Captain, a fire on board is the one thing that scares me the most. You need to be on the ground YESTERDAY if you want to preserve your own life. And YES I would do all the above, I don't care about the pile of aluminum I'm in, I care about my own ass!
Lithium batteries create their own oxygen when burned so no amount of oxygen deprivation would put the fire out if indeed it was the lithium batteries that caught fire
But you can’t mention that too loud……EV’s are going up everywhere!
It’s happened multiple times on aircraft too. UPS lost one as well to a lithium battery fire
@@nicholasdean3869 I know these guys haven't covered it but I think it was either Air Disasters or Green Dot Aviation, the tragedy of UPS Flight 6
EDIT: It was Mayday Air Disasters and Mentour Pilot that covered the disaster. I think there's also a record of the CVR from that flight online and it's just downright heartbreaking :(
Top notch videos bro. Your research and details are best out there. Thank you for your efforts!!
Thank you, I really appreciate the comment.
Fantastic video. If the fire was definitely caused by lithium batteries, no amount of fire suppression would have worked. The only solution is to jettison the cargo, which they were unable to do. So, from the moment the fire started they were doomed!
Sad but true !
Or point the plane on a safe direction and jump with a parachute (which is not possible in these planes).
BTW, today we are in the middle of a similar accident involving a cargo ship and electric cars..... luckily the crew of a ship can escape trough life boats (but the ship is probably doomed)
Lithium Ion batteries are a damnably dubious lot... I don't know if there's any good to come of a new standard of manufacture or what, but it seems like it takes almost nothing to cause just enough "warp" to send them into thermal runaway...
Consider all the hoverboards and E-bikes going "pffft" recently... and there's the e-cigs and vaping mod's blowing people's faces off...
ALL the technologies are pretty great when they work... but damn... one little thing just so slightly off and it's not even a funny inconvenience you can laugh off after the smoke clears and you get over the toy spouting a few sparks or turning into a "burnt-out husk of its former self" or something like ordinary batteries when they pop or fail... People are getting killed by stupid little things. ;o)
@@gnarthdarkanen7464 Li-Fe-Po (usually called LFP) batteries seems a better choice because are very unlikely to self ignite due to a thermal runaway (are still extremely flammable BTW but at least they shouldn't start the fire by themselves) and are also cheaper and much more durable than Li-Ion.... but unfortunately there are also some drawbacks.....
.... LFP are less energy dense than Li-Ion and doesn't like fast charges and discharges, which means that the range will be lower and the charge will be slower....
LFP might be a good choice for an hybrid veicle or for very small city 4 wheels vehicles (not considered cars) or for insanely bulk and heavy cars only (where the range is limited to the range of the battery and the charging stops are not an option).
@@teslacoiler Maybe (with a little luck) LFP's will be a useful "bridge-gap" between the tech thus far, and the manufacturing standard or materials needed for Li-Ion based tech to really take off.
It's worth admitting that I suspect at least some level of the "cheap-*ss knock-offs" being more responsible for the treacherous lemons among Li-Ion batteries. We simply can't allow the factories to "slouch" on productions for the higher production outputs or lowering costs. It's going to have to cost what it costs at some level.
AND I suspect as much because I've seen a rampant "explosion" in popularity for knock-off and "unbranded" batteries among the 18650's that I get for tactical flashlights, stunners, and a few other accessories I have on hand.
In yesteryear's tech', the "tops" were alkaline batteries, but the "unbranded" and "knock-off" communities only got so far against the likes of Duracell and Energizer, so they came out with "Ultra Duty" but those were "alkalide" or "alkaloid" batteries and offered less voltage at best and less than half the lifespan even at the lower ratings. They were only marginally cheaper and terrible...
SO this is the results of that same kind of trend, only on Li-Ion, because I'm not particularly gentle... especially with a device claiming "tactical"... It's for field use and that's tough out here in the mountains... BUT I haven't had trouble yet {knocks wood furiously} At least, nothing fire-worthy. I've bought more than the usual "lemon factor" in fresh-made DEAD ones, though. ;o)
Really amazing job on this one! You said you put in the most time and it shows! I have seen other people say that this is like UPS flight 6 and I was thinking the same thing but this is not known as much. A fascinating video and chilling at times. But thank you for all the research and presentation.
I appreciate that Josh, thank you.
hii
Lithium batteries are 'volatile' under normal circumstances. These things can just explode for no reason whatsoever, I know, as I use them in my vape device, and one 18650 decided to do just that one day, for no reason at all. This thing vented with furious aplomb, and shot across my apartment in a ball of fire, taking at least 5 mins to settle from its mighty discharge. (one battery not getting charged, nor doing anything). It just came to life, and decided to blow. Now, we all know the conditions of any pressurised aircraft, the contractions of such an environment, which can add/subtract many inches to heavy metal under normal conditions. Lithium cells, in phones, laptops etc, all go through this when we fly, and will always pose a threat, hence they are no longer allowed in the cargo hold, but can just as easily decide to explode when the mood takes them ;) They are a necessity in today's world, but one that should be replaced ASAP, as there is now an alarming trend of these things taking on a life of their own, not just in the air, but in other cases, such as the house which burnt down 2 weeks ago (killing whole family), because the lithium battery on an electric 'scooter', parked in the family hall, decided to just vent. Can you really trust them???
Do not underestimate the ferocity of which these things (regardless of size and capacity) can act. They are lethal, and in the right environment, will prove that 10 fold.
Unfortunately, there was not a lot this crew could do about it, as they were doomed from the start. God bless them, and RIP.
Thanks for covering this! Seems like UPS 6 got extensive coverage but I’ve never heard of this crash
It’s amazing how similar they are but you are right, I hadn’t heard of this one either! Crazy that it could happen many times before change was implemented.
interesting how everyone is aware of ups 6 but not this crash even if both involve the same type of plane and same causes
there were only 4 recorded fatal plane crashes during the 2010s, this one, ups one which both crashed due to lithium ion battery fire, other than that there was national airlines 102, which was a 747 which stalled after take off due to load shift( (its a well known crash because someone had recorded the plane taking off and stalling) and turkish/act airlines 1906 which crashed on go around due to basic pilot error
Interesting and educational. Thank you
Well done on getting sponsorship.
Great videos.
Thank you as always.
Wow already getting sponsors
Good news!
Tragic, but one positive thing stands out for me - the Chinese ATC working seamlessly with the KAL crew, with whom they doubtless would have disagreements if you sat them down to talk politics, doing their darnedest to try to save those guys.
This is similar kinda to Swiss 111
More like UPS flight 6 tbh
I would think cargo planes would have anti fire systems.
Unfortunately, Lithium batteries fire consume most of the anti-fire system thrown at it. Like CO2 and water (H2O), Lithium batteries fire will take the O - oxygen for burning, making the fire even stronger. I am not sure what can stop a lithium batteries fire. Perhaps the only anti lithium fire solution is to starve it of Oxygen. I think there are some modern cargo systems that can compartmentize the cargo area into different zones and if there is fire in one area, it can shut down the area and close off the air supply into that area.
RIP gentlemen. Sometimes there’s nothing you can do
Thankfully there were no passengers on board; just 2 crew members! Good video.
As a korean this accident was a controversial event due to links to the insurance fraud but thank fully it was denied and gave justice to the families of the. Pilots
What was the fraud you mentioned?
@@josephphillips9243 life insurance of the pilot
The extinguishing system for the main deck cargo relies on the cabin being automatically depressurised to 25,000' when the cargo fire button is pressed. A reduction in airconditioning pack output and, critically, the pressurisation outflow valves are modulated to facilitate this. Unfortunately, you can't have a negative differential pressure. If they descended to 10,000', the cabin pressure would have to go with it. Checklist notwithstanding, the pilot's early request to descend doesn't make sense to someone who understands the aircraft systems properly. Training issue again?
Sounds just like UPS6!
Curious pilot please look into flight 232. Its pretty remarkable story.
They need a fire watch on board and equatorial stop fires. Or stop lithium batteries on flights
Such a sad story. They never had a chance 😢😑
A cargo aircraft with those many windows? ;)
I know! 😬😬 I forgot to add the note to the captions on screen, but as you can tell I couldn’t get the freighter livery only the passenger variant! I did add a note to the description but I doubt anyone reads that. 😁😁
@@CuriousPilot90 No worries, mate. Excellent video
Not if it was converted right?
The obvious answer is don’t carry such cargo on a aircraft , send it by sea instead , why hadn’t they learned from past incidents with that dangerous cargo. If I was flight crew I would not allow that cargo on my flight.
Dam didn’t know a plane crash happened like 2 weeks prior to you know
👍🏼👍🏼👍🏼👍🏼
Just curious, couldn’t they have done an emergency water landing?
It is fairly well-known and understood that whitewash, composed principally of lime and water, is not a flammable liquid - although it is a bit viscous. What is not so clearly understood, is that while not a source of hazard itself, it tends to obfuscate other sources of hazard, to the point where these are indiscernible. If for example, substantial quantities of whitewash were in the cargo hold of an airplane on fire due to lithium-ion battery combustion, that whitewash might make it difficult to ascribe the source of the fire to the lithium-ion batteries.
1) Why don’t they use a halogen fire suppression system like what is used on ships? 2) Wouldn’t it have been preferable to ditch in the ocean rather than burn up? The cargo was a total loss anyway.
To much info in a situation, where they where on heavy stress.Reading a guiding manual as thick as a book, is very disturbing.
I have a suggestion: when lithium-ion batteries are transported, especially by air, place them in a disposable cargo container. When they catch fire, ditch them, and give fish one more reason to despise humans. (One day maybe, airplanes will have a detachable passenger compartment with parachutes attached. Just blow the cargo, wings, and tail off, and fly the parachutes.)
A shame the World is now so dependent on Lithium Batteries which are extremely dangerous in practically all situations.
So THATS what happened to my package when I was in vacation.
I was 1 year old when that happened
In the near future we are going to see an airliner loss with hundreds on board when Lithium batteries ignite in the baggage compartment. Passengers are told not to put Lithium batteries in checked baggage but never over estimate the average person to F….. it up. Airline rules and procedures are way too vague on the very dangerous possibility
Fire extinguisher and other stuff has absolutely NO EFFECT on thermal runaway LIPO batteries..
so I don´t queite get it here..??
Yumm wonder what was in cargo hold of M-370. Could This be the untold story of M-370?
No cuz a plane on fire won’t stay in the air for 6 hours after catching fire
They should have ditched in the sea earlier, when they knew they were beginning to lose navigation control, maybe?
-26C ??? Really😮
Their only hope of survival with that cargo was to descend immediately to 300 feet and prepare to ditch before critical systems were lost.
At least they would've had a chance. You can't fight a lithium fire...
In a pressure vessel? Absolutely. Fire needs oxygen. If you are able to remove the oxygen, then there's no fire....
At the start of the video, I said It must have been Lithium Batteries that caused this… Ans sure enough it was… Why are these allowed to Fly on planes. They should have been banned after the last crashes! RIP to the crew!
if you know your on fire...#1...why didnt the copilot go try and put out the fire with a fire extinguisher? 2nd... knowing your on fire, why not pancake into the ocean...at least you have a chance, opposed to the aircraft burning up high in the sky...where death is certain!
This business about which switches were in what position, or which checklist they used, or even which simulator they trained in; are all, in this case, completely irrelevant. There was no procedural order, or anything else, that was going to stop that fire from consuming the aircraft. The minute that fire started, their fates were sealed. The only thing that could have remedied the situation, would have been some kind of sprinkler fire suppression system.
Why are these highly flammable goods stored in airplanes in the first place?
Way too much details on pilots background and hours etc etc. Skip the details, not relevant
A cargo/passenger jet how ridiculous, the passengers were just guinea pigs,on this flight.
Lithium batteries. A recipe for self destruction
Which is why ICAO modify safety guidelines after this tragic crash👉stating dangerous goods are allowed on freighter aircrafts, must travel by ship
I allso think battery’s and flammable liquids and pair should be banned
Hi why wasn’t the cargo checked I bleave who ever loaded the 747 991 should be held responsible for the pilots lifes that was lost because of Mel practice negligence thy should be put before the courts and be done for man slaughter and sentenced to ps god bless the pilots and their families
All the cargo was loaded in accordance with the procedures Asiana Airlines required, and the source of the fire could not be determined, there wasn't any malpractice discovered or suspected. It did however, add to the list of similar incidents to allow for more safety measures to be implemented so future incidents could be avoided.
Sooooo.... the plane was scheduled to go at 04h11, its crew showed up an hour before, inspected the plane at 02h15 an hour before they got there, and departed at 03h01, an hour and ten minutes early and also before they got there?
It was probably all that time machine stretching.
I’d rather have an event like this with a Tesla owner.
Its pronounced "A-zhee-ah-nuhh"
Does it really matter?
@@giggiddy it is very jarring to hear tbh. Enough to make me scroll down to see if anyone could confirm that this airline is named in relation to Asia, rather than something else entirely.
Narrator sounds like they grew up in the UK, where we definitely learned about continents in geography lessons.
I double checked this before making the video just to make sure. I watched an official Asiana Airlines advert and the person narrating pronounced it how I did.
@@CuriousPilot90 Wow.- you were thorough with the double-check! Nicely done. Keep rolling - great video, informative and great narration!
@@billmcg1676agreed!
Lol it’s definitely “As-iana” Airlines not “Osh-iana” 🙈😂
It's supposed to be:
"A fire had BROKEN out"
NOT: "a fire had BROKE out" . . . that's a pitiful mistake.
Let's not dumb things down any more than they have been despite the degraded educational system.
You are not pronouncing many of the G's at the ends of words as well.
For example you'll say LANDIN' not LANDING
Of course that could be a British thing like the snooker commentators saying, "balls carreering intead of careening" and "cannon" instead of carom or speaking of the commenTRY box instead of the commentARY box. They all pronounce commentary like Coventry is pronounced. Really sloppy stuff.
You said they "made contact with Seol center . . .
and WAS instructed to climb.
It is supposed to be WERE INSTRUCTED to climb, NOT WAS INSTRUCTED.
I enjoy your presentations and think they are very well done so I hope you appreciate the fact that correcting your grammatical and punctuation mistakes is important to your work.
More:
You said, "The flight continued as NORMAL
is supposed to be: "the flight continued as normally"
Continued is a verb and adverbs like normally have an LY at the end.
You said: "PREVENTIN any further fire destruction . . . instead of PREVENTING
People now say: drive safe instead of safely, I'm taking you serious instead of seriously.
It's sad, this dumbing down.
"Arseyerarnah" 😂 That's like saying "Blittish Airway".
