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!

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.

Sadly for him, Kia were ahead of the game... the Kia Niro EV (and others) has a "Vehicle-to-Load" system. There is (dependent on country) a 230 volt, 16 amp power point inside the cabin. All you need to do is plug the charge-cable into the charge-point on the front of the car, feed the cable in through the window, and plug it into the Vehicle-to-Load socket... Now you can drive forever! (I don't know why Kia did not build the cable into the car, it is quite ugly, and you get cold in winter! Ahh well, small price to pay, I s'pose, maybe in next year's model.)

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.

It was a certification and training problem. A new type rating should have been required, but wasn't. Retraining should have been required, but it wasn't. The mcas was a bad idea, having it fed info from a single sensor doubly so. All because Boeing did not want the plane to require a new type rating, because airlines don't like that. Having the authorities outsource the certification process to the manufacturer wasn't a brilliant move either.

I've been shot at and I've done other things, but to this day the proudest thing I've done was fixing 5 different engine generator problems while in the middle of the ocean between the UK and Iceland. As an electrician flying on a C-130 on our way back home after picking up the aircraft from Bagram AFB, I was of course woken up mid flight to see what I could do. The first time I was woken up we had lost 2 of the 4 main generators and the corresponding electrical busses didn't automatically swap over to the remaining generators to prevent power disruption. This alone is extremely unusual, there are 4 main electrical distribution busses that are connected to main engine generators by 8 contactor rated for 210vAC @ 400hz and 300 Amps. The contactors are arrange in a way where they are automatically energized and de-energized by the generators themselves to switch power between the main bus so no one generator accidentally tries to turn a different generator into a motor. Once all 4 engines and generators are up you can technically loose 4 of the 8 contactors with out getting a single warning and with out loosing a single distribution bus, under highly specific and perfect conditions. Prior to this event the only time i had ever seen two generators go out at once, where the busses also didn't automatically kick over. It was on a C-130 we had just taken out of the bone yard and where preparing it to be flyable again. After the 3 function test flight the aircraft's crew called down with an in flight emergency. When I examined the system some 4awg wires had chaffed each other's multi layered insulations that include fiberglass wrappings and some polymers that give you cancer if you simply pronounce the name of the molecule chain. Needless to say there where lots of scorch marks. As I remembered that incident I checked the fault codes but they where generic and usually fixed by a power cycle while on the ground but obviously we were not on the ground. I also, sniffed around for some magic smoke but nothing. As we where somewhere between the UK and Iceland and still had some power, I had the crew turn off the two faulted generators. I pulled all the circuit breakers for the two generators and then started to remove the paneling for the contactors to make sure nothing was going. Of course nothing was wrong. Feeling fairly safe, I reset the circuit breakers and had the crew reset the generators. They both came on and the busses also came back. Plus all the power readings looked perfectly normal from the voltage to the power drawn across all 3 phases for all 4 generators. So, I went back to sleep. About an hour later the crew woke me up again and told me "we lost three now" I asked "we lost number 3 too now!?" The dude said "No, we lost number 2, 3, and 4" I got up without further conversations and went straight to the contacts ripped of the panels and again nothing. Check the fault codes and the same two had the generic fault codes usually fixed by power cycles. The fault code for the number 3 on the other had was a 50/50 between shorted generator windings or bad control unit. Luckily the control units sit in fairly accessible areas inside the plane and I had a spare one with me as part of my "just in case we need this kit" After seeing the codes, I went up to the crew had them turn off the three generators. I pulled all the circuit breakers for all 3. I went up to the analog contactors and gave them a few good wacks. I pulled off the connectors for the control units for bot gen 2 and 4 then outright swapped the connection between because well, magic. A trick that happens to work to get a plane off the ground that keeps getting these particularly fault codes. The plane almost always flies fine then when it lands we swap them back and the problem doesn't come back. As for the number 3 generator's control unit I slaved in the new unit. With things all moved around I had the crew turn all 3 generators back on and they where all golden. With power all good to go, I finished replacing the number 3 control unit very carefully, even if it was just the mounting hardware. The aircraft flew perfectly fine for the rest of the flight and all the remaining flights back home. Once home i restore the control units for number 2 and 4 back to how they should be. I annotated the maintenance forms they had been swapped back and of course the plane flew fine for the next 2 months or so before I stopped keeping track. At leas as far as the main power distribution systems.

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.

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!

Like the saying goes: A good landing is one from which you can walk away, a great landing is when you can reuse the airframe. Petter (of Mentour Pilot) covered flight 236; he seems genuinely excited at sharing knowledge to build understanding and I can scarcely envision a collaboration of more fun! Maybe a few of your faithful viewers will mention it over on that channel.

That's what I wanted to say too, it'd be cool if you could work with him on aviation videos. He makes faithful simulations of the planes (including the paint job) and his focus is on the pilots and crew experience and what they do wrong and right. Here's his video on this incident kzitem.info/news/bejne/mpibyaWooaWWl3o from peak covid times so less produced than most of his videos.

With a glide ratio of around 17:1 the envelope to make it 65 miles to the airport was easily doable. They were extremely lucky to have and island with an appropriate size air strip that close. Checklists whether followed initially should always be referenced at some point during the emergency. They could have at least slowed the fuel leak sooner.

This is another example where if the pilots had followed their checklist they might have realized what the issue was much sooner. One of the qualities that NASA looks for in astronauts is the ability to always use their checklists and never just wing it or assume they have it memorized especially when distracted by another issue like they were with the oil pressure and temperature they got so focused on it they didn't look at anything else.
