I always keep the seatbelt on especially when I'm sleepy. I don't want to wake up by my head smashing into the cieling.

I flew in Europe a few weeks after this incident and I noticed that the vast majority had their belt on for the whole flight , in my previous experiences, there’s always been a unanimous sound of buckles being undone as soon as the sign goes off, but not on this flight. Did definitely notice a change in culture

I always keep my seatbelt on, especially since I like to sleep on planes, and would need to be awake to hear any fasten seat belt warnings.

I’ve been 100% on board with seat belts all the time since learning of the Aloha Airlines airline where a huge section of fuselage disappeared. The seat belts kept those people from flying away. Only casualty was an unfortunate, veteran flight attendant who was in the aisle.

A razor advert in a turbulence video - imagine trying to shave on a shaky flight… 😂

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.

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.

15:13 & 16:06 Thank you for sharing the clips from my channel Petter! I have been a massive fan of yours and have watched every video you have posted!

I cannot now unsee "CAT turbulance" as an invisible cat swatting at aircraft, because cats are gonna cat.

Today, July 1, air europa flight madrid-montevideo was hit by severe turbulence and had to divert to Natal, in Brazil. According to bbc: "Airport officials said some passengers needed medical assistance and were taken to the nearest hospital. A local medical team told Brazilian media they attended to at least 30 passengers of various nationalities and that 10 of them were taken to hospital. The patients had hit their heads during the turbulence and suffered injuries including cranial fractures and cuts to the face, the team added."

I have been aware of Clear Air Turbulence from a very early age. Back in the sixties my parents subscribed to a children's general knowledge magazine called 'Finding Out', and one article featured a giant, smiling cartoon CAT waving its paw and sending a hapless jet onto a rollercoaster ride! Being a cat lover I've always remembered this idea of using the acronym for Clear Air Turbulence to spell out my favourite pet animal!

Your graphics team is going from strength to strength. This episode was particularly strong from this point of view. My congratulations to your team🙏😀

Been flying as a passenger since about 1960. A lot was 'Unaccompanied Minor', in those far off days, I was chucked on the jump seat to be out of the cabin crews way. Knew my way around a DC3 cockpit before I knew the controls of car. Was ALWAYS seat belt on! Have done every time I fly.

Oh, great, I was a bit bummed that there were no new uploads during the weekend, but now all is good.

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.

Makes me wonder: why are hot drinks allowed on flights? In a bottle or other closed container it seems acceptable, but with many injuries from turbulence accidents being caused by burns, prohibiting hot drinks in open containers seems like it would improve safety

Keep your seatbelt on, even loosley - you can always cinch it up quickly if you suddenly "feel light". Much quicker to cinch it than to plug it in.

What I don't get is why we don't yet have a regulation requiring passengers to be loosely buckled up at all times while seated... there are literally zero reasons not to do so. And to make it worse, you even endanger the people sitting next to you when you go flying out of your seat and crash into them.

This is such great content! My undergrad degree was in physics, so I love your gift for presenting concepts (here, wing-tip vortices) clearly and without dumbing-down. Links to deeper dives and citation of information sources is fun for us nerds out there. It also means that your videos are trustworthy and very responsible.

Am I just noticing the video credits in the lower left? I like that, rather than just borrowing other people's video because we can.

Yes , long haul , get up , walk around , visit toilet , sit down , belt up :-)

Me personally, I like to keep my seatbelt on at all times and urge others to do so too

I just took my DGCA Meteorology exam some days ago, and I already knew about these types of clouds. But after studying and understanding these kinds of incidents, it really makes sense. Thank you so much for making such quality content.

Always a great day when Mentour uploads something new on a new topic!

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.

I never understood why so many people don't use their seatbelts when sitting! When you do it quite loose it doesn't even hinder you with any movements but it can save you when the plane gets into serious turbolences.

Funny how "back in the day" people used to hang out at the bar on the second floor of a 747. I grew up a TWA kid (The cockpit in an L-1011 was lit, literally) and flew often due to my term pass (I could book any TWA flight for free or fly most any other airline for $10-20) and I only remember one instance of turbulence coming into St Louis. I'm just wondering if turbulence is actually worse now or is it just we all have ways to document the incidents so these events get more coverage than before. Thanks for another great episode Petter!

When I was in my last year of college in 1970 one of the participants at a job fair was touting their “Track the Cat” clear are turbulence detection program. That was a long time ago. This problem has always been a big thing to avionics manufacturers.

It would be great to see a video on the hail damage suffered by the Airbus A320 of Austrian Airlines flight OS434 on Sunday 9 June 2024. It’s amazing the pilots managed to land safely!

My dad was a radio operator on B-50s in England at the beginning of our nuclear alert and readiness days. Some missions were extended (over night) as the USAF had planes in the air constantly beside those that were ready for scrambling. The relief crew was flying and dad was racked out. 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 flew on SQ319 2 days before this incident on an A380. it was the first flight for my 1 year old and whilst it was frustrating that she had to be waken up from her bassinet as we tracked over the bay of bengal over Myanmar, 20 minutes later, we understood why. 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

For me a well fastened seat belt isn't just a precautionary measure against unforeseen forces. I find it actually helps my posture in the seat and increases my comfort. Over all a win-win for me, but body shapes and and feelings towards being even lightly restrained do vary.

There's probably substantial overlap between the groups of people who don't wear seatbelts on plane rides and who put their feet up on the dashboard (you know, where the airbag deploys from) for long car rides.

Listening to this while reading there are 30 injured on a flight from Spain to Uruguay due to turbulence...

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!

My dad as a kid always strongly encouraged me to wear a seatbelt in any sort of vehicle at any time - expect and prepare for the unexpected

Remember this, when you are sleeping, always fasten your seatbelt, you don't know when you will wake up smashing your head against the ceiling or being tossed around.

I remember a airline pilot friend of mine told me they avoided lenticular clouds... that was 45 years ago. I always keep my seatbelt fastened. But I want my neighbor to also. I don't want them crashing down on me. Make it mandatory!!

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.

Petter you should really consider teaching ground school. The graphics and the way you explained types of turbulence was amazing, the visual aids were awesome I will never forget the types of turbulence now.

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.

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!

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).

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.

I don't remember it myself, but my mother has a story about us flying as a family to visit her parents and being caught in turbulence while holding near O'Hare. My younger sister and I were maybe 5 and 3? While the other passengers were crying and praying, my sister and I were laughing and calling out "Whee!" like we were on the best amusement park ride ever.

That was great! It is very informative and well presented. Thank you from a grateful Patreon member 😎

Probably one of the best and most informative videos on your channel yet, can definitely see the huge step up in profuction quality. Good job.

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 😂

Nice job, as always. I was interested in those videos showing the turbulence produced by other aircraft. And it’s always glad to hear you remind us that the plane is not going to fall apart!

You are such a pro. I am constantly impressed by the research breadth, quality, and synthesis. Thank you! I think this video will help my girlfriend better understand turbulence / be less stressed when it happens to us. Thank you!

Fantastic Wx lesson. Watch out for those Cumulonimbus with Vertical Development.

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. 😅

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

Such a great and informative video! The first one explaining all different types and dangers of turbulence in a very illustrative and comprehensive way! Thank you, it really helped me get a much clearer picture!

I just saw the news that Boeing reached an agreement to buy Spirit Aerosystems. I look forward to your video about it. Regards

Amazing time with you posting this today and the *other* turbulence incident that happened today and injured people!

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...

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.

Thanks for all you and your teams hard work, Petter! Looking forward to watching this video and coming weekend Mentour Pilot video!

I’ve been watching your channel for several years, and one thing I definitely learned was to keep my seatbelt fasten at all times. Honor most recent flight of Florida. I had to yell at my husband because he took off his seatbelt. He knows to leave it on at all times during the flight.

A much more better sponsor than better help

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.

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.

I love these videos. They are informative and you can actually improve your English skills in a fun and decent way. Greetings from Germany

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 :)

Very interesting and well researched and presented. Thank you!

Why is CAT not mentioned in the safety briefing? Never understood that. People are much more likely to keep their seat belt fastened when they know what the true risks are.

Thanks for covering this

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 :-)!

Thank you for the classic Mentour Pilot episode, I've binged all of your old stuff and really want more like this!

It was the 11th time I had ever been on an airplane. It was a short flight. And our plane “dropped” twice. Think Tower of Terror drop. I’ve been on 137 flights since then and have never experienced anything like that again. The overhead bins popped open- spilling luggage onto people. I was in a window seat and happened to be next to two college linebackers and they protected me from the luggage. I covered my head anyways because smaller random objects were flying around. I had to get off that plane and get on another plane. I was shaking. I’ve never not worn my seatbelt on a plane since, and try to keep my restroom visits to a minimum.

I've been waiting for this video!!!!

Flying to Madrid at night last year, I always felt the plane goes a bit down and then a bit up. For me, it's scary but I learned that was pretty normal. That Singapore was way more violent. Those videos showing the passengers hugging each other after landing are exactly what I would do after an event like that.

Thank you for covering this incident!

Thanks for another outstanding video!

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.

Dear Petter, I love your videos, full of detail and stunning graphics, and this is one of the best! I'm curious about why there's background music though - with so much information to take in and lots to look at, I find it a distraction and start losing concentration after a while!!

another great video, they just keep getting better! Appreciate the work you and your team do 🤩

Once more, excellent job gentlemen

Great video from a great and reliable source! Stay fit.

And just as you released this, a similar occurrence on Air Europa from Spain to Uruguay.

UX45, Madrid to Montevideo had to do an emergency landing just when you posted this video because of extreme turbulence!

I've always wondered what happens to the food cart when siem turbulence is hit. I assume it doesn't hand some awesome magnetic switch to keep it down, and I don't see anything to lock it laterally under the seats, so... I can only assume pain results.

I appreciate the "why can't the pilots just telle before we hit turbulence". I recently had a pax complain that she only experiences turbulence when flying our specifc airline and we need to be better trained to stop making turbulence. Yes, making.

Thank you Colby

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. On departure, the Pilot advised that there were monsoon conditions and to keep seat belts fastened. I noticed on the map that he deviated several times from the flight path to avoid the adverse weather.

The way you described the different types of clouds and turbulence was fascinating

And just today it was in the news that another flight, this time an Air Europa flight from Spain to Uruguay (UX045), made an emergency landing in Brazil after experiencing severe turbulence that injured about 40 passengers, some still hospitalized. Yeah: keep that seatbelt on!

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.

This was one of the best video’s explaining turbulence. I’m a frequent flyer and had a very basic understanding of some of the science but this was like taking a class! Learned a lot. Thanks

Recently went on 5 flights. Halifax, NS to Vancouver, BC. Lots of small turbulence events throughout the flight, warned by captain before every time. Vancouver, BC to Denver, CO. Short flight, little turbulence and warned every time ahead of turbulence. Denver, CO to Orlando, FL. More turbulence on this flight, not horrible and warned ahead of time. I got sick on both take off and landing. This was my first 3 plus hour flight on an American Airway. I have flown probably close to 50 times in my life and that was the first time I got sick. I think it's because it's also the first time I wasn't constantly staring out the window. Could this be it? Next flight from Orlando, FL to Ottawa, ON. Vary little turbulence and told beforehand. Last flight was Ottawa, ON to Halifax, NS. Just a little when coming in for landing. Warned beforehand. A few notes, never felt that much turbulence on Halifax to Vancouver in my life. It was almost nonstop the whole way. Pilots were able to warn us of turbulence before it happened every time. I had alot of fun flying again, 2019 before Covid19 being the last time I flew. Hoping to figure out for sure why I got sick, so it doesn't happen again. Embarrassing and not very pleasant. Thanks for the excellent videos

Great video. Very useful 🙏🏾

Thank you everyone at (Mentor Channel) for putting time and research into yet another good presentation. This was a great recurrent review for me about aviation turbulence. Cheers....

I’ve been waiting for this video reaction from you. Finally you uploaded it 😍☺️

Very good video. Thank you! It helped me a lot.

I was on a flight from London to Belfast with British Airways. The planes nose dropped quickly then violently banked to starboard they to Port, there was more movement. After things settled down the Captain said we had been hit by Wake Turbulence from a plane 10 miles away and 2000 feet above us.

Amazing work

"These types of events are exceedingly rare", though Petr was never to know that there was another event in the hours around when this was released! Flight UX045 has just suffered from this today
