Code Chaos Over Hong Kong | The Near Crash Of Ethiopian Airlines 645
HTML-код
- Опубликовано: 25 дек 2023
- This is the story of ethiopian airlines flight 645. On the 18th of july 2019 a boeing 787 was flying from manilla ninoy international airport all the way to hong kong international airport. The flight was definitely medium haul and within a couple of hours the plane was getting close to hong kong international airport. Now the active runway for landings that day was runway 25 and getting to runway 25 required you to fly to the north then turn to the left and then intercept the localizer of runway 25. If you dont know the localizer is part of the ILS or instrument landing system that uses radio beacons to guide the planes to the runway. The ILS is made up of the glideslope and the localizer. The glideslope tells you if youre too high or too low on your way down to the runway and the localizer tells you where you are in relation to the runway horizontially. Both of them together keep you ontrack and gets you right down to the runway. For the ILS appraoch to runway 25 you needed to hit the way point named river and then intercept the localizer. This would help you line up with runway 25 and from there it would be a quick descent right down to the runway and bobs your uncle. The pilots of flioght 645 flew the aprpaoch into runway 25 and the plane was on autopilot as they approached the waypoint river. River was just 15 nautical miles from the runway so they were getting ready to put this plane on the ground. The autopilot put the plane into a slight left bank as it picked up the beacon on the ground. The plane started following the the beacons down to the runway. The landing was going smoothly. The pilots then quickly scanned their instruments and then came to a sobering realisation. The plane was not descending towards the runway it was headed straight for terrain. Somehow the plane had not lined up with the runway and had also descended well below the minimum safe altitude for the area which was set to 4300 feet. If you dont know the minimum safe altitude is the lowest altitude that youre allowed to descend to in a particular area if you go below that youre at high risk of flying into something like a mountain. That was the case for flight 645. They were in mountainous terrain and the pilots did not feel like finding out where the mountains were with their 787, they immeidaately disengaged the autopilot and took manual control of the plane. ATC noticed that flight 645 was no where near the extended center line of runway 25 and saw that they were headed right for terrain and ATC immediately asked them to go around. The pilots acted swiftly and commanded max thrust from the engines and climbed away from the mountains and out of danger.They made a second approach to runway 25, it doesnt say if it was a manual approach or an ILS one but regardless, they landed safely. Now you might want to know how how close the 787 got to any terrain well the lowest that they got was 3277 feet which is more than a thousand feet below their minimum descent altitude and the scary thing is that they missed a mountain by .3 miles. If they were .3 miles to the right then they would have flown right into a mountain. Which is absolutely scary to think about. Now you have to know the 787 so far at the time of recoding has an absolutely spotless safety record. There are literally thousands of 787s in service around the world and not one hull has been lost, sure they got grounded for a bit in 2013 due to lithium battery fires but it never took a plane down. Finding out why this happened would be key to keeping that safety record intact. Next time around there might not be two pilots who are as attentive or an ATC who kept as close watch as the one at hong kong. So they needed to get to the bottom of this.
When something like this happens a lot of things start happening, some people look at the plane to see if there was something there that could explain the deviation, some people will look at the navigational equipment to see if it sent the jet astray and then others will look through the the

Man makes content, almost literary for free and still feels like he owes us an explanation for why he stopped for a bit. I hope I am not on my own when I say, no, you dont need to tell us anything about why you stopped. All I can say is thank you for all these incredible videos.
Though we do appreciate the earnestness and transparency!
@Talguy21 very true. An example of why we watch him.
I watch so many aviation videos, I was confused initially. When the narration began, I realized how much I missed that voice! ☺️👍🏼
Up! This comment says it all! Hope you the best man!
Came here to say the same. When someone who posts regularly suddenly stops I do appreciate them saying that they're taking a break, purely so we don't worry about them. But he certainly doesn't owe an explanation to a bunch of strangers on the internet who don't even know his name or, before this video, what he looks like.
And when the world needed him most, he has returned
Wow, I got so confused, you sounded completely different for a moment. 😅 Love to have you back with us!
I’m 72 and ex-Royal Australian Air Force. Always enjoy your videos. Very professional and concise. Glad to see you back!
1:57 I genuinely had no idea who this guy was until he said the words "this is the story".
Same here. Nice that he did a face reveal. :) He almost looks like me, with the dark brown hair and skin tone. I'm a small part South Asian.
Sounds so different out of his studio
Great to have you back! Your oneof then best aviation RUclipsrs.
This is absolutely awesome man. I always wonder who the person behind the mic is, and getting this from you, well I honestly wondered if it would ever happen. I'm very glad you made the decision to do it. And, of course, thank you so much for the wonderful content you create. It means a lot to us :) Keep it up, bro.
Hey Arun! Thanks for the upload! Always look forward to your content. It's cool that you havent uploaded in a while, it just builds the anticipation of your next release, which didn’t disappoint. Think that sometimes we all forget that we have lives and other things going on that come up and can't be helped. All the best in your future endeavours and looking forward to your content in 2024.
I agree with the anticipation. It's awesome!
Nice to meet you!! Getting a cameo was cool- you do a LOT of really neat things beyond making awesome aviation videos. I am glad that you enjoy making these enough to come back to it and to make the time for it amongst all those other things. I’m shocked all that took you only three months, tbh! Welcome back ✌🏻
Thank you for doing the first part of this video in person and putting a face to the voice ! I may be old fashioned, but knowing what a person looks like really does make the videos seem more of a personal "conversation" than an informative lecture.
I was getting worried that nothing had appeared on my YT feed from you for a while, so thanks also for the update and it's good to know you're well again.
Someone please do correct me if I'm wrong, but I think there has been a 787 hull loss. I believe a Chilean aircraft has been officially declared DBR earlier this year and reduced to spares after a ground incident.
There was a 737 Max issue a few weeks ago. Boeing has got to get stuff together. Am glad Mini Air Crash Investigation put his face to the voice.
Glad you’re back but sometimes life happens, don’t let everything get too much. Looking forward to more interesting videos.
I am Sr. in IT. I troubleshoot things all the time, as well as write code.
I want to say a lot of your videos help me look at problems fuller.
Good luck on your journey, no matter where it may take you.
Hello, can we do a project together?
@@SP1-media what did you have in mind?
Your health always comes first. Glad you're back mini air crash investigations.
Nice that you are back and doing well!
Would have preferred more frequent updates underway even if they had been very short, but that is in the past now.
Thanks for the christmas video, god jul!
how did you comment 21 hours ago?
My first thought was "dude he makes free videos for wtf are you asking for", then I thought it's kinda cute that you actually care enough to want to know what's up. In all honesty, I love his videos, but sadly wouldn't notice if he's gone for a year since I just randomly see them on my youtube start page.
Hiii, I am so glad to have you back! Great to see you finally and know u r doing fine!
Yay! Thank you!
@@MiniAirCrashInvestigation coincidentally, I also finished my masters in computer science recently and have a deep love and passion for aviation! Cheers!
@@MiniAirCrashInvestigationno need for an explanation...its great to have you back again.👍👍
@@MiniAirCrashInvestigation hi Arun, just watched your video. Somebody else also commented that it is so nice to put the face to the voice. It feels like more of a personal connection. So thank you for putting up great videos and well done to all of your personal and professional achievements. Keep up the good work and I look forward to watching more of your videos. Kind regards from Malcolm in New Zealand.
Thank you for all of your past videos and for your gracious explanation. You've come so far since the early days of the channel. Glad you are back. Stay healthy and the best for a happy and safe new year.
Hey man, welcome back. I've missed your content.
Your channel along with Mentor Pilot and blancolirio are such great resources. Maybe watching vids about plane crashes could be viewed as a little bit morbid but you guys really turn it into an interesting exploration of how things can go wrong, how incidents can be investigated and the causes determined even from the smallest bits of wreckage, and how that feeds back into air industry procedures to make flying safer for all of us.
Thanks for you work, fly safe.
Young man you really don't owe anyone am explanation of why you haven't been able to post as much as you'd like! But with that said, it takes a man of integrity and substance to tell everyone what's been going in in your life at the moment! Keep up the excellent work, and it's so cool to finally see the physical person behind the voice I've enjoyed watching and listening to for so long! Personally, I look forward to anything you post! You're on if my top channels that I watch and follow! So again, keep up the excellent work, and I wish you all the luck and success in the future! Take care always and God bless always 🙏 ❤️ 😊
It is nice to put a face to a familiar voice.
No need to apologize for missing some videos. At least you weren't stuck in prison or something! Keep up the good work.
He's done with the gangs now😂
Good to see you back.. Something to see that Canadian CF-101 behind you. Back in the 70’s I was an avionics technician working for a private company that overhauled the jets for the armed forces. Some of the wires in that plane I put there. Keep up the good work.
I noticed your absence. Hoped it was in the nature of a Hiatus and not the last of your channel. I'm so glad you are back, and will continue to watch your channel. The relationship between creator and subscribers is a peculiar one. You post videos. Others comment on them, and there develops this close-feeling relationship. But in the end you're producing material we all like to watch, and you are entitled to take a break. I'm sure that some folks might feel like they're entitled to an explanation, particularly those who are concerned about your well being. But you don't really owe anyone anything.
Thank you for all that you do to bring enjoyment to people all over the world.
Great to put a face to the voice :)
Great to see another post and see you for the first time. The man behind the voice. Lol
I'm not disappointed.
It's so weird. While this isn't a channel I'm intimately familiar with the publish schedule, and don't always stay super close to, I did seem to realize I was missing some updates just a few days ago.. and here's a timely update! Keep up the up the good work dude. Seen a lot of burnout lately, take your time, take care of yourself, and we'll be here when you're ready
It seems like there's a strong overlap of computer science people and aviation enthusiasts. Knowing you study CS, you'd be in a great position to offer in-depth content to that audience, and get more into the software design that allowed such a failure. I know, most air incident investigations don't find avionics to be a primary cause... But when they do I think many of us could understand and appreciate a version of your videos tailored to coders!
Very glad that you are back!
Yayyy glad to have you back! Thank you for all the great content!
Happy to hear your voice again. You were missed and I'm glad you're doing well.
Hey, take care of you FIRST!! You could go 6 months without posting, appear out of nowhere with a video and, we’ll still hustle over to watch it! You’re a great human being who produces and delivers great content. You owe nobody any explanations. Glad you’re well! Cheers and happy new year!!
Thank you so much for coming back, Arun. I see i was not alone in worrying about you and am glad you got through your health issues and i hope you made it to your Masters! Having been in commercial aviation just shy of 35 years, i so appreciate the fantastic content you have uploaded over the years and what you add with your insights and personality is what makes so many of us come back for more. Welcome back; you have way more friends than you know!
Thank you for all the work you put into your videos. ❤ I’m glad things are settling down for you.
Great to see you back. Glad you've gotten through the high pressure time and are set to move forward into your future.
Also, great to *see* you. It's always nice to pair a face with a voice.
I am so grateful that you are back!! I’ve been worried, but I’m relieved to know that all is well.
Thank you for another great video !
Hey man, I completely understand that you’ve been busy. Hope everything is going well with your masters Great to see you uploading a video
Appreciate all your work! So glad to hear from you!
As many here, yesterday I was thinking about not seeing new videos of this channel, so I'm really happy that you're fine, this new video, and who is the face of Mini ACI 😄
Thanks for everything, 👑
Glad you're back and ok dude! We've definitely missed you man!!💯
Welcome back we appreciate you and your articulate narration and fantastic simulations.
Nice to see you. I have been waiting for your videos. Thank you for them.
It's awesome to finally see the face behind the voice! And I'm glad you're back, but don't feel like you owe us anything! You produce tons of quality content that we can watch for absolutely free. I'm just glad to hear everything's alright!
Also I love the Hippo Plane. Such a chunky boi!
Glad to see you back.
Best of luck on the major!
Delighted to see you back! I have been missing my MACI!
Great to put a face to a voice. Thanks for your videos and glad your back, but remember, take care of yourself first, and everything else will follow! Welcome back!
Soooo glad you’re back! Hopefully traffic picks back up on the channel and you can get even bigger!
It's nice to put a face to the voice. Your videos have always intrigued me because I have been trying to place your accent.
Great to see that you're back. Your videos are awesome. May God bless you
Congrats on your masters! I was a bit worried why I hadn't seen as much from you for a while, hopefully you don't have any further health issues. I'm working through a second degree myself and I understand that it can be very difficult to keep up with the course work.
love your channel, i had been watching your older videos and wondering why youtube was not recommending your vids for the last couple of months! I am glad you're back!
Welcome back !!!!! Thank you for your content !!!!!
Great to have you back! Lover your aviation content!
Hope you enjoy working in the CS field :) it's been my profession for 11 years now and I love it
I’m so glad to see you back and I’m glad you are okay!
Thank you for the awesome content! 🛫 You always do an outstanding job with background and explanations.
So glad you're back! Love your content!
Very glad you are ok! Thanks for continuing to make great content, and please, take a breather whenever you need it. The world can wait.

Most satisfying notification to receive in a while ! Welcome back and thanks for all the videos here !
Good to see you back and still doing well. Always nice to see a face to the name too! 😃
Such a warm and welcoming comment section. It's very rare for RUclips, so congratulations, your channel attracts good people
Great to see you back mate, missed your amazing work ❤❤ cheers NZCH
Thank you for another great video! I am glad you're back.
Glad you’re feeling better friend. I love your videos no matter how long the wait!
Good to see you back and doing good! Also awesome to finally see you in video and relate a face to the voice . Keep up the great work! 😊
Glad you’re back! Wishing you a great 2024.
Arun!! I was just wondering why I hadn't seen a video from you in a while--it's so good to see you again! (And sympathies--I know writing a thesis sucks.)
THANK YOU for all you do.
For those wondering, 0.3 miles is less than 500 meters.
Glad you’re back!!
Glad to see you back and your OK ❤
Glad to have you back sir. I was worried about you.
I was wondering where you’ve been! Glad to see you’re back at it!
Nice to see you back with us I am looking forward to seeing more of your videos.
I came across your channel back in 2020, since then I've been hooked. Keep up the good work my friend. Lol noticed the deep voice now😂 funny how quickly things change in just 3 months.
Glad you're doing well, and the support comes because you've earned it! More than. Good luck in everything you do.
Happy you're back!❤😊
Thanks for the early preview!
Awesome, I'm glad you're doing well and back at it. I really do like how you give little blurb explanations of the various systems and terms associated with aircraft. The ability to parse down something complex to a point that someone without technical knowledge of that thing is a rare and very useful skill.
Yes, that is the best part of this channel. Not long ago some other channel was trying to explain a technical issue and I was thinking "Mini ACI would be a lot clearer".
Good to have you back, MACI!
Glad to see you’re back and doing well! Fantastic video!😸
Bruh I learned a lot from the videos, thank you for that. Man I missed your videos, I search your channel and all of the videos I have watched already. Glad to see you back at it.
Great to see you’re doing well. Thx for another vid. It is so nice to be able to put a face to a voice now. 😆👍
Wooo! Nice to have you back! Hope you're feeling great now, man!
Was worried about you, glad you're back and doing well
Very glad to see you (1 back, 2 literally )!!!! Looking forward for your new episodes!!
Great to have you back, Happy new year from a fan from Cornwall,uk.
Great to see you back. Also great to see the face behand the voice.
Great to see you back my friend I have missed that voice and the great content ❤️
Great to see the man behind the voice!! Great video as always!!
It's nice to finally see your face. Thanks for the great content. Looking forward to more in the new year!
