Most of the time, I can barely even notice its on... I have a habit of fastening it whenever I sit down but once there was a commotion in the cabin and I got distracted, then I spent almost a minute fishing for it only to figure out I've already fastened it and I didn't even register or notice it...

I can keep my phone with charger in one, my kindle in another, and my passport with my kindle, but I had some currency left in my handbag for a tea! I would recommend a similar jacket. I don't use my handbag except to keep a toothbrush and makeup to freshen up and I zip the handbag into my carry on. Less rubbish to cart about and more comfortable. If you have glasses you can keep those in an inner pocket as well. Also, in the absolutely rare case of an emergency landing where you had to leave everything behind, not only are you warm, you have your most necessary stuff with you. Comfy old denim jacket for the win!

Back in 1995, my wife and I went to Hong Kong on a company sponsored award program. On the way back home we flew Singapore Airlines from Hong Kong to Hawaii, a 14 hour trip. On that trip at about 1am in the morning we experienced sudden extreme turbulence without any warning. Some people were laying across several seats and others although seated did not have seat belts on. Suddenly the plane dropped violently about 3000 feet as if hit by a huge fly swatter, and anyone and anything not belted down hit the ceiling or overhead luggage compartments. Even several heavy beverage carts slammed into the ceiling and crashed back down. Fortunately my wife and I were belted in our seats so we watched as everything slammed into the ceiling. It was terrifying and many people were injured. Apparently as we learned later we had flown into a Typhoon. We landed safely in Hawaii hours later and were still shaken by the experience to the point my wife did not want to fly the next leg from Hawaii to San Francisco. She wanted to take a ship but when she learned it was 6000 miles and would take a week she grudgingly got back on the airplane. We will never forget those terrifying seconds of violent turbulence.

For it to be choppy on an A380 through equitorial or inter-tropical convergence zone is saying something. I've done that segment countlessly on SQ over the past 30 years and I can emperically note that it's getting a lot worse. Sadly, the chap that passed away on SQ321 lived opposite the river to me in Gloucestershire and was on a RTW tour. It's just one of those acceptable risks we anticiapte when flying

This was really well-explained and well-presented. The fact that an aircraft the size of a 777 could go through that rough of turbulence is quite interesting

[@beyondEV]

That's misconception, may be the reason people fail to follow the "always keep your seatbelt fastened" recommendation. Any turbulence, strong enough to cause serious harm, is likely to be big enough (area wise), so that aircraft size doesn't matter. (wake t. is a exemption to the rule). It may be different within a CB, but those show up on weather radar and are avoided.

[@johndoh5182]

Why would you say that? That would be like saying the plane the size of an A-380 would have an even harder time dealing with turbulence. It's really the smaller planes that get bounced more by turbulence, POSSIBLY. The design of the plane is going to determine how it deals with turbulence. The 777-ER is used on some of the worst routes for turbulence in the world BTW, one being between the west coast of the US and the east coast of Asia when the route goes up to the Arctic Circle. You can have 5 - 8 hours of being bounced. I remember one flight where there were a few bad bounces and it was rough, like almost continual bouncing for about a hour, while the rest of the time you maybe got bounced a couple times a minute.

My dad was a radio operator on B-50s in England at the beginning of our nuclear alert and readiness days.

He said he woke up floating and then slammed into the rack. he got to his feet and then began floating again for a couple of seconds before slamming into the deck. He got his "stuff" sorted and strapped on a chute. He said that if it had so much as twitched he'd have "popped the cork" and jumped. Turns out that they had hit some clear air turbulence over the Atlantic followed by two massive down drafts that dropped them 10,000 and 8,000 respectively. 😳

I keep the seatbelt moderately firmly fastened whenever I'm sitting down, which is most of the flight. I happened to be walking back from the toilet during a moderate negative G event and my normal walk launched me off the floor for several steps which was a LOT of fun, but I was very aware that I was lucky and got back to my seat quickly and put the seatbelt on quite firmly indeed.

[@MicrophonicFool]

I grew up an Airforce brat on CFB Trenton, Ontario. In the 1970's and 80's, weekly flights across Canada in a variety of aircraft were scheduled as both pilot maintenance training and transport operations between CF Bases. Sometimes these were non-stop and other times they were milk-runs. Service staff, Civilian workers and Service Member families were allowed to attend these flights in most cases, depending on load levels. The cost was approximately $6 to cover the boxed meal provided. One flight I was on at age 14ish was a C-130E flying from Trenton to Vancouver, and later onto CFB Comox. A few hours into the flight the pilots communicated to the Load Master to warn of upcoming disturbed air. LM relayed that message to the 5 or 6 people seated in the webbed seating. Sickness bags were hanging from the webbing just above passengers heads. About 5 min elapsed from the warning to the start of shaking. It started out reasonable enough, but with each passing second the intensity increased toward paint-shaker. In addition to the buffeting the plane was also being pushed in directions not normally encountered on a passenger flight with radical sideway slips and continuous reversing yaw corrections being required by the pilots. I would estimate the event lasted only a handful of minutes, but until it was over it felt like an eternity. I did uncouple the ASB but did not end up using it. It was the closest I ever came to needing one. The rest of the flight was butter smooth, and the landing in Vancouver was magic in a way only Military pilots seem to excel at. Upon our leaving the aircraft, I was next to one of the flight-deck crew and I asked about the turbulence. He had a wry smile and replied that this was a moderate event and that I don't ever want to experience severe turbulence. I am still in full agreement with what he said 40 years later...

[@mariekatherine5238]

I grew up Navy brat in the 1950’s and early 1960’s. Many times I’ve been on transport planes that all I can say, did the “Shake, Rattle and Roll!” If there were any sort of restraints, we kept them on, not only for turbulence, but because four or five kiddies wandering around was simply not tolerated!

[@roberre164]

Brilliant video. In my career as an airline pilot I never even took my shoulder straps off. They move and are not restrictive so I always had them on. Why not. Lots of my colleagues would take them off as soon as we hit cruise though. As a passenger, if I was seated the belt was always on. These upset incidents will always occur for myriad reasons and airlines have been trying to convince everyone sitting down to always wear their seatbelt but sadly some forget, some take it as an insult to be told what to do and there are probably other reasons as well. For pilots the use of the weather radar to avoid growing convective cloud can be a bit of a fine art. The correct use of gain and tilt to expose potential nasty stuff comes with experience and of course you have to manually do this. Auto is not necessarily your friend. Now, I'm off to order a shaver! A close shave is good, if you are on the ground :)

[@headers12]

I find it very annoying when people next to me instantly unbuckle their belts when the seatbelt light turns off, and when the plane just touches down.

[@jeromethiel4323]

My problem with people not wearing their seatbelts is not because they might get hurt, that's on them for being too stupid to keep the belt on. My problem is that their thoughtlessness will hurt OTHERS who weren't so callous. I'm sure it's not intentional, but stupid causes more evil crap in this world than intentional acts. People need to THINK. But no, they're too busy playing with an i-whatever, listening to tunes, or just so far up their own butts that they cannot even conceive of how their actions could effect others.

[@aliyousuf2342]

I have a friend who, way back in highschool, when I was driving would unbuckle his seatbelt as I pulled into our destination. I scolded him multiple times not to do this, but he kept on doing it. That is until I started standing on the brakes when I heard his belt unbuckle and he face planted into the windshield. Only took a couple times and he knocked it off. Moral of the story, some people only learn the hard way.

Greatly increased air traffic with increased recording and communications creates a false impression of increased incidence and severity. Bags were more often checked and stowed and personal items brought in to the cabin were not weighted bricks (electronic devices). Seating was farther apart, less crowded, and more cushioned meaning you were not smacking the seat in front of you on the smallest of bumps. I can imagine that modern latches for overhead bins may be weaker as the aircraft shave weight from every conceivable point, but that may not be the case.

I flew over to Singapore just over a week ago, there was enough convective turbulence over the itcz that made quite a few people unwell. But worse than that, there is a minority of people walking around even when the belts were on. Over the tropics, there is a constant layer of cirrostratus, this can be very turbulent especially during the day. I tend to call that gravitational turbulence, or Kelvin Helmholtz waves. If the sky is white, get those belts on.

[@sthomas6369]

Depending on conditions, mountain wave turbulence can also be experienced a LONG way from the mountains that cause it. An example from my experience flying small aircraft: I was flying from Phoenix to the LA area in my Cessna at night on an IFR clearance. I started picking up the noticeable repeated updraft/downdraft cycle of mountain wave turbulence about over the Gila Bend VOR - almost 250 miles from the San Jacinto Mountains (the mountains near Palm Springs, CA). Since I was IFR (a good idea over the dark desert at night), I couldn't request lower, and performance of my aircraft kept me from flying too much higher to avoid it vertically. The turbulence increased as I got closer to those mountains, and then went completely away as I went through Banning Pass into the LA Basin. Aside: 250 miles of such turbulence in the dark over the desert is no fun in a single engine Cessna! Imagine riding a roller coaster for 250 miles!

Yes, details are important - but a simplistic physics view is that if more energy is present in a “fluid system” (atmosphere), the exchange and dissipation of this energy (heat differential) will create more movement. Add more humidity (same heat, vapour) from “neighbouring system”, sea and land. And then all these complex interactions are still a bit beyond us… As you allude to, an imminent solution must be technical (like LiDAR). Long term… well, that’s a real struggle already. 😅

I just took a trans-Pacific flight on JAL and noticed that they specifically instructed us to fasten our seatbelts over the blanket when we were using one, so the flight attendants could see that it was buckled. This level of negative G force is something that thrill-ride fans dream of. If it didn't have the potential to seriously injure people, it could be fun. Of course, this is why roller coasters have not just elaborate restraints but also strict rules about securing loose items.

[@Zyo117]

I had the terrifying experience of riding a ring coaster when nobody checked the restraints. I was definitely too small, and I had to hold the open roof frame so I didn't fall out past the restraints. I haven't been back on one since. No thanks.

[@simonrook5743]

Frequent flier, I always keep my belt on when I’m in my seat, loose enough for comfort but tight enough to stop me flying out the seat.

[@ilc-nl3yy]

I always keep my seat belt on for the entire flight, unless I have to use the restroom. Other than that, I don't see any reason to take it off.

Good, but on long flights you should stretch your legs from time to time.

What terrifies me on airline flights is the food/drink cart - getting clobbered by it. I am a GA pilot, mostly glider, and have learned that turbulence occurs even on smooth flying days. I have experienced severe to extreme, but brief turbulence, such as a sudden negative g and brief loss of aircraft control under all weather conditions. I wish that heavy food cart was locked to rails in the floor making sure it can not 'levitate' and then land on people.

[@ianbell8701]

Clear air turbulence (CAT) predictive tools have been evaluated in the Bast. Back in the early 2000s I was involved (FTE) in two research projects that employed special forward-looking sensors to sample the atmosphere ahead of specially modified test aircraft. One system was radiometer based and was mounted on a Falcon 20 test aircraft. The other was a LIDAR based system mounted on a Boeing 720B. Neither of these systems was commercially pursued however. We did evaluate these systems at typical airliner flight levels. Today, with many airliners being connected via L-Band and Ka-Band satcom systems, turbulent conditions in the airspace could be broadcast in real time-time to other suitably equipped aircraft. Areas of CAT could be identified and “broadcast” to airplanes operating in the same airspace. Modern digital radar systems such as the Honeywell RDR4000 are capable of sharing real-time atmospheric data in such a way. As you mentioned in this excellent video, there is a cost benefit trade-off involved. Existing aircraft radar systems are able to provide predictive wind shear advisories to crews during landing. Perhaps similar advisories could be provided thru the radar system. Time will tell (more research is needed).

1968 a flight on a DC-6 4 engine prop. Flight from West Yellowstone to Salt Lake City. Thunderheads to 50,000 feet all around,, like flying through a giant's mushroom field,, 10 to 20 miles between each column of cloud. The clear air turbulence between was stunning. a one hour flight that you were EITHER plastered into your seat by 1 to 3 Gs or hanging from your seat belt by the negative -1 to -3 Gs I thought it was kind of fun. Puke on the ceiling, puke on the floor. Interesting,, my stomach rebelled finally after we landed. Walked down the stairs to the concrete and my stomach instantly required a run to the nearest toilet. There is no modern roller coaster that has ever been exciting since. The real thing was enough.

[@zwerko]

I've experienced a a couple of turbulence where at best I'd get a bruise from striking the sidewalls with my head, possibly quite worse, had I not had my seatbelt on. Now I have a habit to fasten it whenever I sit, I don't even think about it. I question the sanity of people who don't put it on... Like, why?! It's not constricting in any way, you can barely even notice it, and it can quite literally save your life.

[@tomriley5790]

All in all the crew responded entirely correctly to this upset. One thing worth bearing in mind for pilots used to operating in Europe is that whilst it's rare for storms to reach very high altitudes in Europe (60,000+feet) it's relatively common in the tropics. The passengers that got thrown out of their seats only have themselves to blame. It really annoys me that individual responsibility has been entirely abdicated by people who feel that they can ignore safety precautions when imense efforts and care is going into keeping them safe. Keeping seatbelts on (relatively loosely) is the least inconvenience. Shaving even with a Hansen razor is probably not a great idea in the air either :-)!

[@kevinwong1988]

This accident can happens to any flights. My condolences to the British passenger.

[@MarkLee-li4ob]

I kept mine on coming back from Bangkok this Feb. We hit a bad area over the Middle East. Enough for the flight attendant to hit the ceiling. The turbulence was enough to lift people in their seats. Was an awesome experience. Everyone was making concerned moans and whimpering which would naturally make any seasoned flyer slightly sweaty. My 2 year old daughter got me through it. She was giggling the while way through 😂

[@zwerko]

Bonus roller-coaster ride, what's there not to giggle about? 😉

[@garman1966]

This happened to me while flying to Australia from LA in about year 1980. 3 hours into the flight at cruise at night over the Pacific the plane suddenly experienced violent positive and negative G forces, engines spooled up, and then we went into a dive. I was seated in the middle of the plane about half way from front to back and was sleeping with my seatbelt on. People, mostly flight crew in the back hit the ceiling, and after the dive, when I thought we were all going to die, we evened out at a lower altitude, stayed that way, and made a return to LA that took 4 hours. The plane stopped on the runway and was surrounded by ambulances and fire trucks. I saw at least 4 people carried out of the DC-10 past my row on stretchers but there were probably more taken out of other exits. I wish I had the ability to find the report on this incident. If someone knows please comment.

I fly between LA and the east coast of Asia and there's almost ALWAYS a lot of turbulence, so yeah, seat belt on is well ingrained.

[@steveunderwood3683]

Between HK and LA/SF several hours of turbulence shaking you too much to sleep is not uncommon. The areas of turbulence over the Pacific can be huge.

[@heybirader]

If the seatbelt light turns off I always loosen my seatbelt but do not release it. I don’t release it just for the only and single reason what if there is sudden turbulence. I’ve never experienced heavy turbulence as I’m not a frequent flyer. That doesn’t change the fact that you should not do it.

[@quinnocent]

I just want to add that LIDAR module costs are dropping so rapidly that a lot of cost-benefit analyses from even a few years ago are now really inaccurate.

[@Neal_Schier]

I, as well, am surprised that there is not more mention of LIDAR costs dropping.

[@kenoliver8913]

That's especially so as the study Petter quotes saying that LIDAR would cost more than it is worth was from 2002 - 20 years ago, when LIDAR was still an ultra-advanced experimental thing. LIDAR costs have nosedived since those days so undoubtedly this is now just plain wrong.

[@zwerko]

A bigger problem with LIDAR for detecting fast air movements is that it's not really reliable. The cost will continue dropping, but it's hasn't been getting more reliable lately...

[@LesterPowell-qi3qg]

[@MrSteadfast]

Keeping your seat belt on at all times when you're seated on a plane is just plain common sense. Clearly, not everyone has common sense.

[@Wintermute909]

Is it tho? Imagine you knew nothing about airplanes and the fasten seatbelt sign turned off....you would very likely think that the airline just officially told you that in their extremely safety conscious opinion it is now very safe to remove your seatbelt. And tbf to them it's not that unreasonable to think that, otherwise why even bother having a seatbelt sign? Why don't they replace it with an actually relevant sign?

[@MrSteadfast]

@@Wintermute909 Just about anybody who flies has heard of air turbulence before, just like anybody who travels by car has heard of accidents. There are too many arrogant people in this world who think an accident will never happen to them until it does.

Excellent graphics explaing turbulence. Thanks for another great episode.

[@y_fam_goeglyd]

A long time ago, when I was ~12, I went on my first flight from the UK to Munich to spend Xmas with my sister and her German husband. The whole family went, including my other big sister (we came in two batches of two girls with an 8 year break between #2 and me, #3 lol) with her husband. Mum was a pretty frequent flyer on this route, but she was terrified of it. (She was incredibly brave because whenever my sister needed her, she'd fly over asap.) About half an hour or so before getting to the destination, my brother-in-law who was in the middle seat between Mum on the aisle seat and me at the window, needed to go to the loo. Mum was able to get up to let him past (she was a quite large and cuddly lady 😊), then she sat back down. He ended up in a queue - I think many people were planning to not need to stop in the airport! The weather was not too bad, but by now we were in & out of a lot of cloud. It wasn't windy, and despite being on an older jet (even for the end of the '70s. Might have looked older than it was because it was Dan Air, if anyone else is old enough to remember them lol), it had been a smooth flight. I'd heard about turbulence - the typical "run over a pothole-full road" sensation - and was surprised to not have felt it. Until the plane literally dropped - a lot! Those in the loo queue had ended up in the air briefly and then found themselves on the floor. He had to crawl back to us and then get past Mum! She was as white as a sheet and grabbing hold of the chair so hard we couldn't get her to move. He couldn't get past her so she _had_ to stand! Eventually, despite being thrown from side to side, going back up and dropping (it lasted a good few minutes!), we were able to unpeel her hands, and get her up enough so I could pull her to the middle seat. We all buckled up, but by then it was essentially over. During the worst of it, the captain (I assume) came over the tannoy and yelled (no exaggeration!) at everyone to sit down and buckle up, and finished with "Girls, sit down!" to the stewardesses. There was no "Ladies and gentlemen, we are currently experiencing a bit of turbulence, it's perfectly normal but please sit down and put your seatbelt on," it was full-blown orders with terror in his voice! Me, never having experienced turbulence, just thought to myself "Ah, so this is what they mean." Believe it or not, I wasn't afraid! (I am now as terrified of flying as Mum used to be, but I don't know why.) A few years later I flew over on my own with BA and we had the "pothole" turbulence and the captain came on, introduced himself and did the calm sort of speech I'd been expecting before. Weirdly, I liked that because it made me feel like there was something "solid" beneath us! 😂 I really felt for the people on the Singapore flight. That must have been horrendous!

I always sit strapped in, and honestly, it never occurred to me to wear it loosely. I guess it is the same for the non-belters. Maybe something airlines could remind passengers of!

[@willykang1293]

Close to two years ago, I read the aviation news in my country Taiwan, and there’s a coach pilot (… with his son🤔) flying their light aircraft, crashed into the field, and dead. Because the terrain in Taiwan can be super tricky, it can close to the mountain up to 15000 feet, and also close to the ocean with just few kilometers away. I immediately thought that it might caused by mountain wake turbulence. The updraft and downdraft in Taiwan should happen often in flying. If that’s a light aircraft encountered that convective turbulence in that scenario, I guess that light aircraft would crash as well. Clearly, keep seat belt on is right way to do.

[@kenoliver8913]

Turbulence is always a much bigger issue for Cessnas and the like than for commercial airliners. OTOH they do not fly high enough to encounter jet stream related turbulence.

[@dementeddrewSA]

This is the video I was waiting for. Thank you! I was a bit nervous returning from Thailand last week in the light of several of these stories making news.

My dad worked for a major airline. With friends and family all over the US, we flew often. We would hit turbulence, and he was relaxed and even slept through it. I high school, I started A&P school, and learned a lot about aircraft structural ability. In the US Navy, I was an aircraft structural mechanic, and turbulence never upset me. But I keep my seatbelt on, because every aviation mishap shows, the passengers with the best outcome, are belted in.

[@cantstandtheestablishment4004]

As a meteorologist, I can tell you unequivocally that turbulence is not getting worse. The jet stream has and always will result in turbulence, and flying around thunderstorms will always result in turbulence. We are flying around in and ocean of air. Wind shear, waves, and instability exist all over the place. That has not changed and it never will change.

[@nikogorny965]

Please let me know if I am over simplifying this but isn't there a very logic and simple solution to this problem? Historically speaking aircraft were not able fly over many kind of weather clouds like the much loved DC-3. this is now changing with the modern airliners that can fly at a height of let's say 12 km. Isn't there any possibility for the manufacturers to optimise future designs to accommodate for example better suited wings and so on for higher operating altitudes? (please let me know if I'm wrong)

[@rdmgwinn]

Back in 1977 we were returning to the US off the coast of California in what looked like a brand new 747. We hit what I guess would be called clear air turbulence. No warning just instantly "stuff" going everywhere. We were lightly belted in but still felt like we would go flying within the cabin. Quite a bit of interior damage to the aircraft. Broken overhead bins, popped wall panels cracked dividers etc.. They took quite a few injured people off the plane, including three flight attendants before they let us deplane. Cabin was a mess from one end to the other, exterior still "looked" new. I had learned from MANY trips across the Pacific in USAF EC121s to always keep my seat belt on. With the flawless ride of the 747 almost relaxed a bit too much. Since, if I'm not moving about the cabin belt is on and a bit tighter than it was that day.

As a crew member with more than 22 years of experience, I do not find that there is more turbulence now than 22 years ago, except for one caveat, in my company we fly A330 and A350, the A 330 is much more stable and moves much less, the A350 It is a real beater, it moves much more than the A330, and one of the reasons is that it flies faster and hits bumps faster, except for this, no, there is no more turbulence now than 22 years ago.

I remember my first experience with convective turbulence in flight training. I was in a 172, power at idle, nose down 30 degrees and I still had a 300 feet per minute positive rate of climb. It was uncomfortable until I learned how to see and avoid as well as manage it. I learned that the AMDAR data provided by the MADIS system provides the best means to avoid clear air turbulence. Learning how to read a skew-t log p that’s transmitted real time is a tool that most professional pilots don’t know about, even commercial pilots whose Boeing aircraft are continuously transmitting the data. PIREPS are great, but the data provided by the aircraft via the MADIS system is even better. My airline currently uses this system to transmit the weather data as well as use it for flight planning. Probably one of the best kept secrets in aviation weather planning in the world.
