Original aircraft, modified to use X-plane datarefs in the FDR file to make the vertical fin, engines, and horizontal stabilizer separate at specific points in time:
forums.x-plane.org/index.php?...
I edited the .OBJ file in AC3d to separate the tail/APU cone from the aircraft, then animated them so that they would fly backwards based off an unused dataref in my .FDR file. Same with the four engines, and the horizontal stabilizer. It's using the same animation system used to animate the landing gear, flaps, control surfaces, fan blades, etc.
Original livery, modified to add the tail number and JAL logos on the wing and fuselage, and other minor tweaks:

Minutes before the 747 crashed near Mount Takamagahara, the pilots tried to stabilize the aircraft by performing a series of rapid thrusts but with little effect. In the recording, the last moments before impact could be heard when Captain Takahama exclaimed to communications, “We cannot do anything now!” after the pilots’ final futile attempts at raising the aircraft. Upon impact, the 747SR exploded.
Medical staff had found four survivors out of 524 passengers in the debris. They had also identified bodies with such injuries that suggested many had died from shock and overnight exposure. One doctor said, “If the discovery had come ten hours earlier, we could have found more survivors.”
In the aftermath of Japan Airlines flight 123 crash, the company’s president Yasumoto Takagi had resigned from his post. The company’s maintenance manager, Hiroo Tominaga, committed suicide to atone for the tragic event. Susuma Tajima, the engineer who checked and cleared the 747SR for takeoff before its final flight, also took his own life after the crash.
Apparently a bunch of top pilots tried this in the flight simulator and they lasted an average of 12 mins, much less than half the time this crew managed to keep the aircraft in the air for, which is a testament to their skill and bravery. Most experts don't even know how they managed to keep it in the air for so long.
And they did that in a simulator. Those brave pilots kept it in the air for double time in REAL life. I think they did that because they were heroes, and knew that many lives were on the line. God bless them.
I feel like a reason why these pilots were able to keep the plane in the air because it was in reality and they did everything they could possibly do to keep the plane in the air.
They Can Do That Because They Put They Effort, They Intention, They Energy, ETC To Save The Plane... Because They Experienced it In Real Life.... You Crash, You Die..
Unlike The Simulator One Just for Investigation
@@Def1nedNoob But the thing is... in a simulator there is not the same impetus and deadly seriousness of the situation like in the real thing. When you already know you'll be perfectly safe no matter what you do your brain doesn't work for survival. But for those pilots who were in the plane they obviously thought very fast and had to try everything imaginable to try flying the plane.
"I think they did that because they were heroes" Nonsense. They just did their job like true professionals. That's what *anybody* doing a responsible job is expected to do, no "heroism" involved. When can talk about heroism when somebody goes *outside* and *beyond* their designated job or position. Example: Regular people saving somebody before a trained rescue crew arrives are heroes. They're not trained for the situation and it might be dangerous to themselves but they go beyond their positions in life.
Trained pilots are professionals and they're trained to go through emergencies. All pilots knew they may find themselves in a bad situation one day and expect to be prepared for it.
Also take into consideration that the real pilots were suffering from hypoxia while this was happening
Huge respect for the pilots, they fought until the last minute, truly a hero. RIP
If they wouldve worn their O2 masks like theyre trained i wonder if they wouldve saved the aircraft and landed somewhere succesffuly.
@@dberry6257 I dont think so... the hidraulics gone with the part of the tail. They didnt know it... 😔😢
The captain's daughter became the flight attendant of Japan airlines
Hi, can i put some this version. Japan Airline Flight 123 czcams.com/video/hDZhmdi0vuc/video.html
Respect is an understatement,.....they need to give these pilots their own national holiday of remembrance.
8:27 "You can speak japanese now" The controller suspects that the situation is serious... Respect for these pilot. What a tragedy...
The fact 4 people actually survived this devastating crash, is beyond me. That is very scary.
More like infuriating. According to the 4 lasting passengers and the crew in the plane that sighted them, they were a lot more survivors. But, like said in the video, someone from japanese authorities said no.
The scene where the Self-Defense Forces flamethrower was used for the first time
@@International_Internet what?
whats sad is there could have been more survivors but emergency services were told to wait until the next morning to arrive because they thought nobody could have survived that. Many people died because Emergancy Services were told to wait until morning.
@@joaquinlezcano2372 Yeah, but you have to consider the wellbeing of the rescuers too. The landing would've been at 4am, in a helicopter, on the side of a mountain. They were professionals and concluded that the rescue was too dangerous to happen immediately.
Also, there's just about a billion other factors to consider, like transporting victims and the possibilities of fire, sudden weather changes, etc.
Maybe they could have saved a few more. Maybe they could have killed the entire rescue team and screwed over the remaining survivors. We don't know anything besides what happened, and they didn't have the luxury of knowing even that
The pilots Fight for their life for over 30 minutes, that's scary enough to listen.
After this event, they run several simulations about this fly, none of them could keep that plane in the air for as long as the crews did, a true testament to their pilot skill, it's a shame they just died like this...
It's horrible. Reminds me of the crash of the Polish LOT 5055. The crew was fighting for 31 minutes before crashing just short of the runway
@@FilmedbyEdmund witam polskę, tak zgadzam się
@@piotrusiek4208 pozdrawiam
And yet in an utterly hopeless situation they still saved 4 lives
As an airline pilot, this is one of the only accidents I can recall that truly scares the living shit out of me. To know that your only viable option is to ditch, and that's if you can actually get it somewhat under control, AND that any scenario almost certainly ends with your death... That's awful.
I've felt twinges of panic only a few times in my career, but I cannot imagine what it's like to have that feeling for half an hour straight.
What can you say? They really gave it a good go. RIP lads and ladies.
As the Captain goes down with the ship, the Pilot goes down with the plane. RIP
Assuming the pilots did everything perfectly was there any way to save the plane?
@@MalumZeth Multiple flight crews were afterwards put in a simulation of the incident, and none of them could save the aircraft. In fact, they all failed even to stay airborne as long. As far as we can tell, it was not possible.
would a water landing be possible?
@@ThatHippyDuck Depends how you define "landing".
I doubt any landing they attempted would be controlled, so really it would be a crash.
Finding an airport in their state would be nigh on impossible. So better to land somewhere you can reach, rather than somewhere you may not be able to line up, and could therefore result in excess ground casualties.
It's not a great set of options, but it is what it is.
There’s a few photos out there of the cabin, taken by a passenger. Most were of the plane as it was taking off, but two were of the incident itself. One was with the oxygen masks hanging from the ceiling, and with another of a flight attendant demonstrating how to wear the masks. The camera’s film roll itself managed to survive the crash, but the family with the camera didn’t.
However, the son of the family on the plane with the camera, Ryoichi Ogawa, didn’t go on the plane with his family; as he was a rebellious teenager who didn’t want to go to Disneyland Tokyo with his family. After getting the camera back when the investigation ended, he donated the photos to JA’s museum of the wreckage.
Ogawa now lives with his two sons.
What’s crazy is that people are finding bits of the plane to this day. Two weeks ago on August 6th someone found an oxygen mask near the site. Just as strange, it was found only 6 days before the 37th anniversary of the crash. May those who died rest in peace.
You're not GOD TO SAY RIP, ONLY THOSE IN GOD IS IN PEACE
@@reckontonottobemoved What?
@@reckontonottobemoved Excuse me?
@@reckontonottobemoved NOBODY CARES
I cant imagine the moment he knew his family were all lost in the crash, the feeling is too overwhelming. The true tragic event of his life. May all those who were lost tests in peace, even though I am 30+ years late on the prayer.
Incredibly brave pilots, fought the giant tailless beast the best they could
Fought by not putting their masks on lol
What do you expect? They stop fight and ask a coffee to flight attendant to a last life minute conversation and walk of life? So commonplace.
Indeed. The bird was just too wounded to save. It's insane they kept it flying for over 30 minutes after losing all hydraulic pressure. 3 hand picked flight crews tackled the same situation in a simulator... not only did none of them land safely but they all couldn't even fly half as long as this flight crew.
@@Lemosa3414 What make you think wearing the masks will help them in fighting the uncontrollable plane? The result is the same.
@@cshong87 if you read Wikipedia it says they likely had hypoxia which might have lead to some poor decisions on their part. The masks would have prevented that.
they able to fly that tail-less plane for 30 mins much respect for the pilots.
rest in peace to all the people lost their lives.
I always wondered what control they could gain from if they ordered everyone to converge and sit as close to the center of gravity of the plane as possible, then ordered the flight crew over the intercom to move the heavy service carts fore and aft to adjust pitch.....or another variation of the same thing.
@@SuperPhunThyme9 i don't think they know that their plane's tail is gone
Tail-less and with no hidraulics at all.
@@SuperPhunThyme9
With "if" we would put paris in a bottle.
@@SuperPhunThyme9 mmm no, as far as I learned in Aerospace Engineering, the slight change of CoG wont affect anything. They are too small. Plus they suffer from both uncontrollable dutch rolls and phugoid motion.
This is by far the best aviation reconstruction video I've ever seen, way better even than on TV. As an aerospace engineering student it was also really cool that you added explanations on flight dynamics eigenmotions, such as the phugoid and dutch roll!
Agreed 100%
eigenmotion? Markov processes??
@@Overhemd Oh, I was just wondering what eigenmotion was. Eigen just kinda stuck out from lin. Al.
@@taspine they are common oscillating motions in an aircraft. The ones that I know of are Short-period (nose going up and down), Dutch Roll, Spiral, Asymetric roll and lastly Phugoid. You can look them up if u want to know what specific things cause them
@@Overhemd hmm okay. Markov might be a tight fit then.
23:31 "this may be hopeless.." the captain just felt that about 10 minutes before the accident shows how skilled he was. I really, really feel bad for him and the crew. They're all heroes for me.
Don't give him the credit. First of all, he didn't even take control when the explosion happened. Second, the guy didn't want to make fuss to the company when his plane lost control.
I don't know about you, but if my plane with 300 people on board loses control, I want to make as much fuss about it as possible.
@@harryshuman9637 are you okay?
@@kopowitz Yes, are you?
@@harryshuman9637They were probably so damn scared when the oscillations begin that they weren't able to think straight and you wouldn't have did it any better. It's easy to be cocky when you sit safe at home but the tremendous fear these guys had to deal whit is beyond anything any man can stand.

You could have asked for rudder maintenance inspection.
@@tensevo Rudder maintenance had nothing to do with this accident, it was a pressure bulkhead that failed and blew the tailfin off.
@@Gohan-chan ok, I suppose what I meant to say, was, you could have asked for proper repair, inspection and maintenance, the point being, you could have asked for more in response to OP.
@@tensevo the thing about maintenance is that they actually do a ground pressurized check and that's it, this incident is really unfortunate...

Those pilots were true heroes, and like you said, I feel the same every time I watch this, a deep sadness and hoping they manage to do it, but in the end the reality strikes harder again making me know it was impossible to do something. Many pilots around the world tried to recreate this accident only to realize they would have crashed within 1 or 2 minutes... Those JAL123 brave pilots kept the craft flying around 30 minutes at least they gave time for the passengers to write goodbye notes for their families. Huge respects for them.
Dang, this is the most accurate and precise recreation of the accident - rip to the poor souls on board
As a professional in the aviation field, I never ever forgot this air crash. The crew fought an incredible fight to save lives, true heroes. Rest in peace to all who perished.
Absolutely impressive recreation of a horrific ordeal. The fact you labelled everything, translated, described and detailedly set out everything is just what we all needed to visuallise the scenario. What struck me was the cabin crew, set in what the stewardess instructions to passengers. The last words they heard...
I myself was a flight attendant and in that ordeal I would have been terrified. She was so calm. May god rest their souls
Honestly given how absolutely hopeless the situation must’ve seemed, that there was even 4 survivors seems like a real victory, and testament to the skill and bravery of the pilots.

I can't hold back the tears listening to them, they were destined to die and still fought every second. There is no greater pain to know it is your last flight, the affirmation that the lives of everyone on board is also in your hands.. it's too hard to bear. Rest in peace.
That is exactly why Pilots and Flight Crew need to/must have metal helmets, rocketpacks or jetpacks strapped on to them before every flight till landing at said location, thaat way if anything happens, flight crew and pilots can fly away if the plane blows up or splits apart and live to tell the story.

Edit: Wow, this video is really taking off! Thanks for all the wonderful comments and for watching, it really makes my day! For those asking for more flights, I've decided to see if I can reconstruct the Columbia disaster. One report has enough data to allow me to reconstruct part of the orientation after the telemetry cut out. However, bear in mind, the JAL123 project I started in 2018 and had been working on for the past 3 years up until the video was published, in my own spare time when I wasn't at work or studying for a Bachelor's in MIS. This was also originally going to be a one-time thing. But seeing the great reception on this has nudged me towards making another one. Columbia might take a little while.
Also, I'm seeing a lot of comments suggesting that they try a water landing. I see two problems with making such at attempt. The first one being that ditching on water in an aircraft with fully working controls is difficult at best, and has only been completely successful with no fatalities a small handful of times.
Second, landing on water in the case of JAL123 would be highly unlikely to be successful. The dutch roll would likely make a wingtip or engine hit the water first, and then you're cartwheeling across the surface just like Ethiopian Airlines 961. And that's assuming the aircraft's pitch is level when it's at the ocean surface. The pilots couldn't reliably control the pitch of this aircraft, certainly not enough to ensure that it doesn't impact the water nose-down, which would surely kill everyone instantly. Then there's the waves to consider, and the water was probably not particularly calm because there were thunderstorms in the general area that JAL123 was routed around before the decompression. (If you wondering why I didn't include weather, it looks like in X-plane it's an all-or-nothing deal for the general area. There's probably an addon somewhere to add storms in a specific spot and time, but I couldn't find one.)
Original comment:
Just for the record, if anyone wants to know why I did not do my own voiceover. One of my pet peeves when gathering the CVR audio from the broadcasts was the fact that there were parts that had voiceovers which I could have otherwise included (some during speaking parts of the CVR audio no less), which annoyed the heck out of me. So I wanted this video as pure CVR/ATC audio, nothing more, nothing less. Once I finish transcribing my audio in Audacity (A lovely open-source audio editor) itself via labels, I intend to upload the entire Audacity project to a file sharing service, and link it in the video description.
Thank god you didn't. This video is perfect.
@@DatamasterCorporation Thanks!
this sounds strange, but i like videos like this. do you plan to make more videos like this?
Landing in the water also dooms those who did survive, ensuring that there would have been no survivors. The frigid cold water + the sinking airplane + the panic ensuing would result in some people being trampled to death, while those who did manage to get out of the 747 would have to tread water and/or swim to shore. This would have been easier with a life jacket. Then they would also have to survive the night the same way as they did in real life.
On the other hand, if the crew controlled the roll to redirect the lift component of the wings, they could descend faster. If they did the correct ditching procedure, they probably could ditch the plane safely. I agree the pitching would have made it impossible to do a safe belly landing but by slowing down, the force upon the passengers would have been less. F = m(v-u)/t. If they could have slowed down enough on a water landing, "u" would be less, and "t" would be higher since the sudden impact results in a small "t". This would reduce the number of injuries sustained as a result of the collision. Perhaps it is not needed because from what I remembered, more people survived than the 4 who did but unfortunately passed away due to the long response.
Such a courageous and honorable crew that did the almost impossible to save lives! RIP.
just by losing the hydraulic is literally is already super impossible to land but if the hydraulic and the most important part of the plane missing it's totally not gonna land without more than 400 souls gone

Hearing them scream 'its the end' dude that really got to me. These pilots fought until the very end like warriors.
It's a miracle that even 4 people survived this
I think that is also credited to the pilots that were finally able to gain altitude about a minute before crash and didn’t hit the mountain head on. I’m sure the initial first impact of the engine 4 and wing tip grazing the top hindered the impact significantly by slowing the plane. Crazy how like 10 or more could’ve survived the crash had they not let them suffer the whole night with injuries unaided.
After talking to the four that survived, they said that closer to 40 people survived but died before rescue could get to them

40年近く経った現在残念ながらこの事故について知らない世代が増えてきており風化が進んでいる。その中でこのような再現度の高い動画が現在でも作られていることは本当に大きなことだと思う。
本動画の意義はとても大きいという点について全力で同意したい。
その上で誤解を恐れずに書くが、事故について知らない世代は興味がないのと知っても教訓を活かせない立場ならむしろ問題はないと思ってる。
そもそも教訓を活かすべき航空業界において本件は今でも広く知られているし、最も重要な原因と対策についても数多く研究されている時点で十分だと考える。
しかし教訓を活かす立場にない一般人の興味を引くために今行われている事、それは「事故の悲惨さと恐怖」の周知活動。
苦しみや悲しみだけをシェアする行為は興味を引かない、墜落寸前まで戦った人々や生き残った人々を称える前提でこそ興味を引くし本当に忘れないでほしい事はそこにある。
これは別件で個人的な思いだが、某震災被災者として毎年同じ日にそういう類の報道を何十年も見せられ続けた挙げ句「風化させない」とかテレビで言われるのは結構キツイ。

最後の10秒くらいで機首が一気に下向いてるが、実際生存者は髪の毛が文字通り逆立ったと言ってるので、本当にそれこそ飛行機内なのにジェットコースターから下る(実際の速さはその数十倍だが)ような感覚だったんだろう
This is so heartbreaking. They all did their best until the end. The voices of the flight attendants trying to keep everybody doing the right things-ah, that is so hard to hear. May they all Rest In Peace
what's incredible is that after so long wrestling with this horrifying situation it seemed they actually got the aircraft stable towards the end...amazing pilots....RIP
First of all, it's an absolute miracle that anybody survived this flight! Secondly, I'm pissed as hell that the Japanese authorities/government called off the Yokota search and rescue helicopters. My dad was a military policeman in Chitose, Hokkaido, Japan, and attributes this to Japanese pride and ego. Third, ultimate respect to the Japanese pilots! The amount of stress they were under is off the charts and the fact that anybody was able to survive this is a testament to their skill and the design and engineering of the Boeing 747! What an elegant and beautiful yet strong bird she is! And finally, ultimate respect to you, Gohan-chan for putting this all together! This is the best flight crash simulation I've ever seen and was absolutely riveting! It brings everything together: flight data recorder, cockpit voice recorder, cabin recorder, air traffic control, flight data, control inputs, etc. It was absolutely riveting and fascinating to watch everything together simultaneously! It really immerses you in the environment with the flight simulator overlayed with all the data and what it must've been like for them and the enormous amount of stress that they were under, how hard the crew had to fight and how crucial communication and coordination/crew resource management is in a situation like this! Bravo! My hat's off to you Gohan-chan! Excellent work! Subscribed!
Yeah apparently a large amount of people died after the crash due to no help arriving for so long, and that on a route between Osaka and Tokyo, that is insane
@@Icetea-2000 days? Before you spread misinformation maybe get your facts straight. It was 14 hours.
An initial scout helicopter was turned away AFTER reporting no signs of survivors. No rescue was sent during the night due to the difficulty in landing helicopters in a mountainous area at night. (allegedly).
Of course, every denies they turned rescue away, and American reports twist them turning the scout helicopter away as turning away rescue efforts. Which ever you look at it does suck.
Allegedly 50~ people survived the initial crash and died do to the elements and injuries, but don't make it sound like they waited "days".
@@jpHouse You seem offended as if you were part of the Japanese search team, the point stays the same, it’s horrible how they acted
@@jpHouse This is on par with defending the Uvalde Police.
@@chaostheoryfilms I'm not defending the action or lack of action taken by rescue teams or the decision behind it.
I'm correcting misinformation that paints an improper picture of the situation.
I think it's horrible people that could potentially could have been saved if action was taken sooner died. But it wasn't "days", plural, as OP said, which is what I'm trying to correct.
Its really sad hearing ATC desperately trying to contact them after it crashed. Btw, you and your videos are severely underrated! Huge amounts of effort has been put into your videos. Keep it up! :)
It was sad so sad that they tried contacting them my heart goes out to everyone who died and those brave men who fought to save everyone
Could you please make more of these? The stats that were on screen of the plane's every move and the pilot's every decision was absolutely fascinating. You did a tremendous job on this and did well in paying respect to this accident.
"Put your heart into it!!" (CAP)
They fought aganist all odds for hundreds of lifes, they deserve to be resting up there, they're heroes!!
It's so sad how the Captain's motivation goes from that first quote to "This may be hopeless" and then "It's the end!", rest easy, we thank you for your extraordinary work :]
its hard to imagine that 4 people actually survived this
Really?!!! How???
There was more, but they died out.
@@Anonymous-nr3ww it was just simple a pure miracle 😢
@@jihanmutiah there might be more survivors if the Japanese authorities allowed the Americans to rescue those people. Based on what the story is

Such a valiant effort by the crew to keep their stricken plane in the air against overwhelming odds. I’m haunted by the Captain’s voice as he screams with growing urgency and audible desperation “Power! (Pause) POWER!” while he and the First Officer both wrestled to pull them out of the dive. And then, “It’s the end!” Much respect to the pilots for their courage, tenacity, technical skills, and overall professionalism even in the face of death. Like true heroes they fought bravely to the bitter end. May all of the souls lost in this terrible and tragic accident rest in peace.
This crew deserves to be remembered for their bravery. They never had a chance, but fought like hell until the last moment.
If I'm not mistaken there were attempts by other crews in simulations as part of either concurrent, or independent investigation (and/or studies into engine-only control methods) to attempt to do better than the fated crew of JAL123 here and it is reported that no simulation crew managed to get even half the flight time this crew managed to pull from this fatally wounded bird.
That’s true. No other Pilots could keep the bird in the air for nearly as long as the flight crew of jal 123 did.
I'd say no flight sim can be compared to having to battle it irl, the thought of having 500+ people relying on you imo should be a good enough reason to put everything you got on the line. But alas, in the end they had done everything they could
@@samuelginting3213 And I also doubt that they took out oxygen from the simulator, if they can even do that in flight simulators esp. the ones they have available back then.. and whether they can do this legally.
@@samuelginting3213 And while that is certainly motivating, you're also not potentially crippled by fear and in the same state of being "excited" in the simulator... that's not always a help. It's easier to make the right call when a) you already know what's coming and thus you're more prepared and b) you might be more willing to try certain things when you don't have to worry about this immediately causing your death.
No one survived this situation longer than around 10 mins in the simulation. The pilots at JAL123 battle it for around 30 mins. Their skill is insane
Insanely well built. That was surely one of the best reconstruction videos I've seen in a while. Fantastic job!
Brave Japanese pilot's they fought for their lives and the passengers lives until the bitter end. God rest their souls.

This simulation is much more detailed than most simulations. Great job!
Honestly this is extremely underrated. There was so much work put into simulating the flight! 10/10
This has got to be the best simulation I've ever seen. Even though I'm quite familiar with this incident, I watched every second of this. Incredibly informative.
What struck me was how beautiful the scenery was. When they went up over Mt. Fuji, with the sun setting over the horizon...what a contrast to the sheer horror of their situation.
Bro!!! Huge respect!! This is the best reconstruction I've ever seen. Everything is amazingly detailed, synchronized voices with the plane model, good explanation and even transcripts of what everyone said. This is legitimately amazing, hoping to see more of these from you. Specially the gol 1907, if possible. Thanks for the amazing content!! + A sub
Good Job on recreating the accident, I never heard the full cvr and they clearly fought till the last minute. RIP
5:59 "put your heart into it!" Wow
Wow, thanks for pointing that out!
This is so good that it's hard to watch without tearing up at multiple points. I have so much respect for the pilots who fought so hard and an awful new appreciation for just how terrifying this must have been for passengers, right until the end.
Thanks for taking the time to create an accurate and easy-to-follow reconstruction of this horrific crash. For someone like me who's not familiar with the terminology or with the operation of aircraft, this helped me get a much better understanding of how it happened than listening to the audio on its own or reading a detailed description could.
墜落するとわかってても頑張れ！と思ってしまう
そうですよね。ずっと応援しました。
When I find myself, an aviation enthusiast watching this several times in a row learning stuff from this, I can say with a strong amount of certainty that YOU DID A GREAT JOB WITH THIS RECONSTRUCTION!
Wow this video is seriously incredible. I usually don't watch these types of simulation videos because I have very little technical knowledge about aviation and can't follow them, but I watched all of this. Great description of what is happening up top (I think?), excellent translation and presentation of the comms, clean visualizations of flight data and no unnecessary clutter.
The time and effort you must have put in to this video is incredible, this is the best audio, visual and descriptive video of this tragic accident on the CZcams by far. Thank you.
For the record, this took me approximately three years to make, from when I started my research and began expanding the Wikipedia article on it, to finishing the video and uploading it. All this was done on and off in my spare time, while I was working on my Bachelor's degree and working 30 hours a week.
That includes the research on how to actually work X-Plane's flight replay system, gaining video editing skills, and learning how to work 3D animation programs to do stuff like removing the tailfin and engines. Those parts alone I believe took about 3-4 months to master. Lots of trial and error, for sure. Since that time, I've been spending a lot of spare time in 3D modelling programs like Blender and Unreal Engine 4 (mostly playing around with and modifying DBZ Kakarot models).
This is a very good and detailed video! Thank you for sharing, may all lost in this tragedy rest in peace. :(
これは凄い再現ですね。悲しい事故です2度と繰り返してはなりません。亡くなられた乗員、乗客の皆様のご冥福をお祈りします。
こうやって映像化してもらえるとどういった状態だったのか初めてよく分かりました。
このような状態の機内の状況を想像すると胸が痛くなります。
今度このような事故が無いことを祈ります。
Meanwhile in Japan some people still think the crash was the captain's fault. Because the recording was not revealed until 2000, which is 15 years after the crash, the misunderstanding still persists. According to the captain's daughter she was heavily insulted about her father's "wrongdoings" until the truth was finally revealed in 2000.
This is a remarkably well done reconstruction of the accident, the best I’ve seen yet. Nice work! Gives me a newfound respect and appreciation for what these pilots and poor souls endured.
Please do more of these.
RIP to all lost JAL 123.
Excellent, detailed and respectful reconstruction. I never knew about the SELCAL calls, it is quite an eerie sound it makes. Utmost respect to the flight crew, an impossible situation but they never gave up. RIP to all on board.
Worst part is when the captain says this is the end, cant begin to imagine how scared everyone must have been, depressing...
Brilliant video. The most well done recreation of any aircraft event that I've ever seen. You'll never see a better analysis and more information than this.
I'd read everything I could find about this in English and even read the accounts of the stewardess that survived, but still didn't know that last dive had been caused by some confusion in the cockpit. I thought it was that the phugoid motion had gotten out of control and pitched the aircraft into a very steep, uncontrolled dive. That's the way it was shown in the TV shows about this disaster, too.
so much detail, and the video is so clear and nice looking. Thank you so much for uploading this. I've always found this crash equally heartbreaking and fascinating, how the flight from Haneda to Osaka is so short, yet all of this happened so quickly. I'm glad that the victims are no longer suffering anymore. Thank you again for uploading.
Checked your channel out and you went from Forza to this. Thank you for visualizing such an incident. May the souls of the victims of this tragedy find peace and may this incident serve as a lesson for airline safety.
This is such an amazing video and the work that's gone into it is astounding. Well done. There was probably a brief time these poor pilots felt they might be able to land and save everyone. So tragic. RIP.
This was one of the most informative and fascinating simulations of this tragedy I’ve seen. Well done.

They fought gravity like tigers. Absolutely incredible effort.
I haven't even seen one minute of this video yet, and I can already tell it will be the best JAL123 recreation I've ever seen.
It looks so well done that I'm actually going to save it for later. It's impossible to over-celebrate this crew's effort, and it seems you've honored them very well.
Thanks in advance for this outstanding effort! 👍
OUTSTANDING! 🤩
I'm tempted to rave for about 3000 words, but I'll simply state that your 30-minute video did more for my understanding of this accident than over 3 hours of video documentary viewing, and around 120 hours of written materials research. I just dug out a 5-year-old account and reset the password so I could ship an additional like your way. It might not do much for you, but I can't resist the urge to encourage.
As for CZcams, I can say with all kinds of confidence that you could conquer the niche of air disaster videos if you wanted to make more of these. Allec Joshua Ibay, X Pilot, The Flight Channel...none of those guys can compete with this kind of comprehensiveness.
In terms of air disaster material, this blew everything I've ever seen right out of the water. Zero contest. Thanks again for your effort!
Thank you for making such a comprehensive reconstruction of the accident! Keep up with the good work!
This is by far the best simulation I've ever seen for this accident event. My only suggestion that I have would be to put a darker background color behind the ATC Comm and the Cockpit Voice Recorder dialogue so that it can be read better with clarity against the white text letters. Other than that, you did a great job on this.
This is so good. I had to stop it multiple times to see everything on screen. Amazing and informative

You deserve a publicly given award for this video. Amazing.
Truly impressed with the incredible amount of work that it must have taken to produce this animation. Excellent job with all of the information provided, pitch, power, roll, control wheel position, CVR and ATC all in real time with a moving map as well. Bravo!!
So bloody sad.. They almost had it so stable until the flpas were lowered more.. Heart breaking.
the moment they try to retract the flaps that's where the lift goes bye bye
@@Raze145 Yeah, I see that :(.. The plane looked really quite stable at flap position 3 to 4 .. Kept stable throughout extension, but they lost precious speed and like you say, once they retracted the flaps that was it.. not enough altitude to recover. It's such a shame, they really did their best and fought to the end with what they had, its just heartbreaking to see they almost had it..
@@Vanadeo yup, same thing happened when i practiced my landings, dont retract the flaps too quick or u will literally drop like a stone when it’s hot outside. This was me in a 172 that weighs 2000 lbs. Imagine a 747 which weighed 600k lmao
@@Vanadeo honestly, had they not extended the flaps they would’ve been fine but idk. Was not clear where they intended to land cus the flap wasnt extended via hydraulics so maybe there were inconsistencies. It is after all the 80s when the 747 was absolutely dogshit in terms of safety.
It was more of a lift imbalance, and applying more power to the left side engines that caused the final dive. Flaps 5 seemed the most stable position, flaps 10 is where it started banking even with slightly higher right-side thrust
I respect the pilot and everyone on there who try to work hard to the very end.
Excellent video recreation. Seeing it in real time gives you an idea of the terror everyone aboard JAL 123 experienced during those final 33 minutes of flight. The heroic flight crew never gave up on the aircraft, their passengers or themselves. It's absolutely incredible!!!!!
Much respect G-C, the amount of effort you put in this video really shows.
Great job man, I've never seen such detailed simulations of a accident before. consider doing UAL232 as well.
I'd love to, however the FDR data hasn't been published for UA232 as far as I can tell (which is rather disappointing to be honest, I was really hoping to do it next). There's only a map on the accident report, not even any graphs which I could digitize the way I did with JAL123. I'd have to hand-fly it and essentially make it up as I go along, and that's not particularly appealing to my inner perfectionist.
@@Gohan-chan hey buddy, could you do Aeroperu 603? It’s a very personal thing to me and I’ve been trying to do something very similar to what you’ve done for JAL123. It would be an honour if you’re able to that.
@@Gohan-chan I really really tip my hat off to you for creating this video, words cannot explain how I feel.
@@Gohan-chan can u do af4590
@@critcalfrog9163 This is the first older flight I've seen with published FDR graphs (besides JAL123), so I'm considering it.
Thank you for your work in digitizing & syncing the CVR, and editing the internal files in X-Plane. And thank you so much for contributing to Creative Commons. Absolutely amazing job!
Thanks! I actually saw your own render of the tail separation, and it was one of the things that inspired me to do it in X-Plane.
@@Gohan-chan Hey I was wondering how you extracted/reconstructed the flight data from the last few seconds? I tried to just connect the dots and that seemed to show the plane only rolled at the end?
@@Michael_cnv That was one of the more difficult parts. What I couldn't grab from the graphs themselves I interpreted with the help of the information in the accident report regarding the plane's orientation in the final moments (pages 79-80, 107), and tried to make it look reasonably good with a lot of trial and error. So it's probably not exactly the same orientation as it was when it impacted, but it's pretty close. It definitely didn't help that the graphs had the resolution of a potato, and the DFDR only recorded most values once per second.
These pilots were heroes. Rest in peace to all the victims of this horrific accident.
This was such a greatly made video. I enjoyed every single second of it. Much love
This is amazing, the quality of this recreation is just insane!
Rest in Peace to the amazing crew who tried to save their passengers.
Amazing job! This is probably the best reconstruction I've seen
Fantastic job, very impressive reconstruction. It takes the viewer more into it than the ACI episode.
