As an airline pilot, I applaud your very accurate description of what happened on this aircraft. Proper analysis, proper terminology, and simple enough for a non-engineer to understand. The big bonus here is the opportunity to teach physics, chemistry and engineering with the story as a background. Well done!

Off on a Tangent: A person I worked with for years was on that flight. There was of course a class action suit launched by the passengers after this. They reached a settlement nearing $ 50 million Cdn. Out of that, the legal team received nearly half. While that sounds outrageous, these kinds of suits demand huge time in research, and payment of expert witnesses. The rest of the money was divided in terms of more money going to passengers who were injured using the emergency slides. A broken ankle on an elderly person, for example, can lead to substantial loss of quality of life. My co-worker friend suffered no injuries, and was stoic enough not to mention the nightmares and such. At the end of everything, he realized $ 8000.00 Cdn. Basically made whole on his expenses, and not much else. So when you hear of these big settlements, don't assume that the plaintiffs are making out like bandits.

Largely correct but one point of note, even if you don't have "fly by wire" flight controls you still need a RAT. The 767, CRJ, and E145 I've flown all have RAT's and are not fly by wire. Reason being at a speed of .84 mach there's not enough mechanical force from both pilots put together to be able to move any of the primary flight controls. Simply too much air resistance. RAT's can either be an additional electrical generator or a hydraulic pump directly powering the PCU (power control unit) that the cables hook to that move the flight controls. Hope this cleared something up, overall excellent video!

I love how you so much love the technology you talk about, I can see in your face how much passion you have, I've been an electrical fitter for almost 50 years, I build control panels from scratch and after all these years I still love my job, great videos

Amazing and passionate storytelling. Great dad! Inspirational engineer. So many badges of honor that you wear. Thank you!

As usual you managed again to explain an issue in a simple way but to the core. Like my late father who was a pilot, instructor and examiner for technicians told me, "Its not hard to explain things in a complex way, but to explain things in a simple way you must really understand and know what you are talking about."

This is such an interesting story! We need more engineering stories like this!

Amazing story and amazing job explaining it to a noob like me. As someone who occasionally flies for work, when you described the cabin lights going out and the second engine shutting down (and the ensuing silence) I literally felt sick. I could imagine how tense and worried I’d be. Great video.

This video is such an incredible lesson by using an emotionally engaging story to mentally step through the engineering process of designing a well balanced and practical machine with just enough emergency gear! ❤

Props to the pilots and flight attendants! Amazingly skilled pilots! You saved lives

as an engineer myself I fully understand the conservation of energy you demonstrated. sometimes when you instinctively understand things you tend to gloss over important details parts when explaining them to others. I commend you Jeremy, for putting together a vary concise, complete and understandable demonstration. well done!

Your best video. Great story telling + clear explanation. Great work! Thank you.

Jeremy following you in Rwanda, well done your lectures are helpful to us, in developing our minds on those complicated issue due to unperfect explanation we did got in past

An EXCELLENT video, Jeremy! I spent a lot of years doing or supporting aircraft maintenance, both in the military and for a major airline, so I was already familiar with what a ram-air-turbine (RAT) is and it's importance. What I particularly like is your engineering and physics based approach to the discussion. I hope you are inspiring lots of young people to pursue the STEM topics. Another interesting topic may be the "Gimli Glider" incident in Canada, several decades ago. A large passenger aircraft on a trans- continental flight ran out of fuel about halfway across. The complicating factor here is that Canada was in the middle of transitioning from the British Imperial measurement system to the Metric system, revenant documents were not updated, and more. One of the pilots knew the area, because he had served at a (closed) RCAF base nearby. That knowledge, and the RAT, resulted in a successful landing. I believe the aircraft was repaired and put back into service. At this point I would normally rant about the idiocy of the USA not making metric mandatory instead of just the current status of "legal". (The other two countries are each smaller than most US States.) But maybe that can be another video.

Any landing U can walk away from is a good landing. Truly fascinating story about a) backup systems as safety factor i.e. redundancy in engineering, & b) pilot error i.e. just do & ignore the checklist which is is own backup system. In today's world I'd expect real time software analysis & output warnings suggesting possible fuel leak(s) or other conditions based on monitored inputs pilots see individually.

Beautifully described, thanks.

Love your work Jeremy. You are a great communicator.

A fantastic story with tons of education mixed in! I hope you make more like this one.

Man, excellent video! That's an incredible situation and you've done a fantastic job of explaining it to us!

Well done. You are a gifted educator

I really enjoy your videos, your delivery style etc. Your parasitic energy loss explanation was really well put. Thanks.

Fascinating! Thank you!

Mr Fielding always explains everything that all layman can understand. Just awesome as all his videos, always awesome.

Great video! Thanks for sharing!

Wow, THIS is the type of information I love you for sharing!

Great video. I will definitely watch others and have been following for some time. My grandfather was an airline mechanic back in the 40s-60s. My father worked the reservation systems. I broke the chain and became an engineer rather than work for the same airline. Keep up the good work.

This is one of my favourite air "disasters". Your explanation of conservation of energy reminded me of a few months I bought my 2000 Honda Insight. Was filling up and a guy at the fuel station told me I should put a windmill on the front of the car attached to a generator to charge the batteries. That way, it would recharge as I drove and I'd never have to buy fuel again! I tried to explain that "in this house we obey the laws of thermodynamics" but his suggestion was to just use a large windmill! Finally after going around in circles a few times I told him that he was a genius with a world changing idea so he should invent himself and make billions. I always wonder if that guy went home and started playing with oscillating fans in his garage.

Clear, concise presentation by a very easy to listen to person.

This guy is so very good in description and delivery. Great story teller!

Excellent explanation of the scenario of a improbable cascading chain of events that can result in aviation mishaps. You mentioned loss of cabin pressurization. That is also a function of the engines via bleed air system. Thanks for sharing.

I just watched this video. It's the first one I've ever seen of yours. Excellent job. I'll be tuning in in the future.

Thanks so much for your videos. You are a blessing to us all.

Mr Fielding, thank you for your attention to detail as usual.

Well done. Here's a scenario I faced many years ago that could be used to teach how the much simpler systems on small piston engine-powered aircraft work; namely, how the magnetos will keep the engine running even if the alternator fails. It isn't enough of a story to make a video about, but it could be a useful nugget nonetheless. I was piloting a Cessna 172 many years ago in instrument conditions at night on an IFR flight plan between Corvalis, Oregon and Seattle. At one point in the flight, I caught a very brief scent of an electrical fire, but very brief. Then I noticed the ammeter was indicating zero charging. Fortunately, I had plenty of battery-powered emergency light sources and a battery-powered GPS mounted to the yoke. I shut down as many electrical systems as possible to conserve aircraft battery power, talked to ATC, checked weather at alternate airports (all were below minimums), then ultimately elected to continue to Seattle where the weather was better. The engine hummed along just fine. I checked in with ATC about every 10 minutes (radio and transponder). By the time I got to within about 15 miles of Seattle the weather had cleared and I completed the flight VFR, and had plenty of power left in the batteries to turn on necessary lights and radios for the final phases. At the time I was a nugget instrument rated private pilot, so you can imagine my stress level, especially as I had my kid with me. Thanks again for this video.

Thanks Jeremy. Great video. Cheers

Jeremy! You are a great guy

Nice work, thank you!

Great compilation of facts and how it all ties in together!

Thank you for the great content. One of my favorite channels. I wish we had teachers like you in our grade schools. You are very talented.

Great story, with just the right amount of technical information.

Awesome video, thanks Jeremy!

Thanks for the Explanation. You made it very interesting!

As usual, a great video. You present the content in a straightforward way without clickbait-y titles.

You have a great channel, Jeremy,. Thank you for making these videos. 👍

excellent job describing in detail what happened. You did lots of research

Thank you very well done. Thanks for sharing

thanks for the story.

Thanks dude.

Absolutely superbly done,😁👍

You Sir are brilliant.

I knew on Smarter Every Day you were worth following. You more than deliver. Well done.

I loved this video. Well done

You have a great talent in explaining and delivering a presentation. Thank you.

Jeremy this a great video . I was stressing as you told it. Love your videos buddy

Excellent video!

A fascinating story well told from an engineering and aviators perspective. Well done!

Thx kind Sir. Your hard work is greatly appreciated ✌

Fantastic explanation of this account! Thanks for sharing!

VERY well done Jeremy. Well research, well presented by you, and well produced. Thank you

I clicked on this link and was happily surprised to see your face. I haven't seen your videos in a couple of years, despite the fact that I'm subscribed to your channel. Nice to see you again. Well done on the video.

Great presentation

Excellent 👌

You are a very skilled story teller!

Curiosity and not being afraid to dive in, that's a really good way to learn.

I really enjoyed this! Learned a lot!

Great show mate! x

A very informative video, your delivery style is so calm, relaxed and informative, keep at it!

Dang Professor Jeremy, I'm digging the AV vid. Keep hem coming🙂

Excellent video Jeremy, thanks for sharing 👍

The cup illustration put the pieces together for me.

Thanks so much Jeremy! You are a great teacher.

You are an amazing, generous and kind man.Awesome story, very well presented, best to you Jeremy from James

What a great story. As it turned out, I was actually stationed at Lajes Field in the Azores when that happened. It was amazing to see how far the plane bounced and then to see the wheels and tires worn down to the axles because as stated the brakes locked up. Needless to say the runway was covered with pieces of metal from the rough landing.

love this content .... keep up the good work ...

I love that you're into planes! I've been a huge fan of yours since you were picking through the curbside trash and making tools out of old vacuum cleaner motors. Now that you cover another of my favorite subjects, your channel has achieved a new level of awesomeness. You should cover some 400 hz motors that come in aircraft and advantages and disadvantages to high frequency electrical systems. It's really cool that a motor at 400 hz can produce 30 hp and not be much bigger than an electric drill.

Thanks jeremy 😍

Such a great video! This was educational and very captivating!

Wow wow wow! This was absolutely incredible. Not only was your story telling ability superb, I learned about a number of airplane specific mechanisms I had no idea about

Excellent video! Enjoyed this very much!

That's really really impressive.

Amazing video! Thank you! I didn't see part 1, and I never miss your videos. Jayman...

Mentor Pilot collaboration!! You are amazing and so is he, great team 👏

Wow! Great video

Wow, so fascinating and so well done!

@20:16 I wouldn't say that cabin pressurization is sacrificed, because it already stopped working when the engines stopped spinning.

You are a great teacher!

This was a absolutely fantastic video. I am blown away.

Been watching your stuff for years and have loved your approach to engineering(and life) education. As an aviation engineering nerd as well, I love this crossover arc. One topic I would love to see covered is geared turbofan engines. Lots of interesting engineering tradeoffs there I haven't seen covered anywhere yet.

Wonderful Jeremy! Not only is your new series a great augmentation to videos focusing on air emergencies, but it also brings in the very important part to describe the engineering aspects built into the systems to mitigate problems. Your style of the presentation, including little demonstrations such as the oil viscosity impact really brings people closer to the engineering. I really think this might indeed get more people interested, if not actively involved into technology. I have followed your channel for years and it is amazing to observe how your projects, communication style and outreach to the next generation of engineers just is on a constant steep incline. Keep up this great and important work!

Excellent.

you Sir are brilliant

You are an excellent presenter.

Very well explained!

Holy Moly this was insane. Very good story telling! Enjoyed every sec 👍

Super informative and interesting video!
