Seems relatively constant according to this graph: https://icao.usmission.gov/air-carrier-turbulence-related-in...

that seems to be just total number of incidents, not corrected for increased air traffic over the last 30 years

Good point.

I've never seen turbulence like this. And until fairly recently I didn't know it was really possible. So it's a bit like "why don't people wear a welding mask while cooking?" It was never even a risk that I had considered before.

> So it's a bit like "why don't people wear a welding mask while cooking?" Your kitchen does not have staff telling you to make sure you are wearing a welding mask. It may also lack appropriate indicator lamps that tell you when it is a good time to wear your welding mask. It is also not standard practice in all kitchens. It’s actually not like airplane seatbelts at all, where they are ubiquitous and the risks of not…

People are constantly bombarded with seemingly unnecessary warnings. I frequently assume that these warnings are to insulate a company from legal trouble and not really to protect me. This might be an American perspective.

Yup... I still don't understand why people decide to not put on their seatbelt while being seated. It's not like you have a lot more freedom of movement without the seatbelt? And it might just save your life in events like this one.

Do you fly over the tropics? To me it's not so uncommon to experience heavier turbulence when crossing the equator to the tropic of Capricorn, haven't experienced turbulence bad enough to see people pushed straight through the cover of the oxygen masks but I've been in a couple of flights where I experienced big drops in a split second, thankfully never seen anyone badly injured just some poor soggy bastard that was thrown around in the bathroom and people hitting their heads on the overhead bins.

I just always wear my seatbelt per the flight attendants' instructions, "keep your seatbelts fastened while seated" is a recommendation in every flight I've ever taken in my life.

Tragic, horrid and going to make a lot of nervous flyers more nervous. I've been through some pretty heavy turbulence in my time, but thankfully nothing this severe. I've been through enough though to know that a lot of people don't take it very seriously. I've been on flights with screaming passengers, and _very_ quiet British Marines, both in reaction to some pretty nasty air, and I'm always surprised that turbulen…

When I walk in a city I don't spend my time constantly scanning the sky and every building around me for a potential falling object. Or research the structural history of every bridge I drive over then spend hours avoiding certain ones. Or a hundred other rare things that do kill people but statistically not often. Everyone dies one day and everyone has a single life. I don't see the point of spending that one life i…

It's not "constant fear" to just leave the seatbelt buckled. It literally requires less thought and effort to just leave it buckled, because you'll inevitably be re-buckling it when the plane encounters turbulence or lands.

Using PPE is not about living in fear, it's about taking appropriate precautions.

So let's say the media started a campaign promoting wearing a helmet all the time. The anti-helmet people would be painted as reckless, feckless, and generally deplorable. All the celebrities would endorse wearing a helmet at all times. There would be New York Times editorials about "those people". Questions: Is this still about risk mitigation? If yes, are you at risk now? Why don't you wear your bike helmet at work…

A smart, independently minded person, would do the following risk analysis: - Planes fly through the atmosphere in varying conditions. - The conditions that lead to uncomfortable or dangerous turbulence are not at all uncommon. - These conditions are unpredictable and have little warning. - Wearing a seatbelt is a very minor inconvenience, and will protect me from the worst of the harms that can come from common turb…

> - These conditions are unpredictable and have little warning

Not true at all. The vast vast majority of turbulence incidents are very well predictable. It's not 1930 anymore.

> - The conditions that lead to uncomfortable or dangerous turbulence are not at all uncommon.

Except your flawed logic in the previous point flows to this point. The question isn't turbulence but unpredictable severe turbulence which is much rarer. About 1 per million flights I think which is far from common.

> A smart, independently minded person, would do the following risk analysis:

Given the flaws in the risks analysis I find this sentence hilarious.

Horrible news. Speaking of the physics involved, I was thinking: if it's just free fall, caused by gravity and no air sustaining the wings, this should not happen, right? Some random Quora answer says that it's because during turbulence there is actually air pressing wings down and accelerating them down faster than gravity, and that's why you hit the ceiling. Intuitively that makes sense but, can anyone confirm? Edi…

Same question here. I suppose that it also hurts (maybe even more?) on the way down because once the wings gain lift, you experience g + lift + your momentum going down ?

I haven’t experienced much turbulence in maybe 15 years, whereas I remember in the 90s I experienced tons of turbulence in almost every flight. I am not sure if this is something modern airliners have been designed to deal with or avoid, or not. Has anyone else experienced this or is my memory just faulty?

According to a study reported by the BBC, it should be getting worse thanks to climate change: https://www.bbc.com/news/science-environment-65844901

Did you read what OP wrote? It's not mostly about wearing your seatbelt when seated but mostly about never ever ever leaving your seat. That's the constant fear part.

I'll be the first to admit that I held conflicting views: For one, I never thought someone could die from turbulence (besides a medical condition such as heart risk). At the same time, I'm sure certain falls/impacts are quite lethal even in very short distances. Yet, i dont understand how turbulence makes a plane fall 6000 ft in 3min, unless the automated (turbulence?) avoidance system engaged and caused the injury i…

> unless the automated (turbulence?) avoidance system engaged

There is no such thing. Civilian airliners don't have any automatic avoidance systems - they can only notify the pilots when there's a windshear (drastic wind change), another plane very close by, terrain close by, etc. But it's only (very strong) warnings, and it's impossible to detect/predict turbulence.

Why do you perceive wearing a seatbelt on a flight and minimising time out of a seat as such a high cost/inconvenience? I hear this line of thought a lot, particularly nowadays around masking to avoid COVID, and I’m always intrigued by this idea that avoiding this tiny act that barely impacts you is somehow sticking a big middle finger up to fear

> particularly nowadays around masking to avoid COVID

Ah ok, as I suspected a covid authoritarian that’s deluded and ruthlessly mocking ANY recognition of cost in the cost-benefit analysis of safety measures, meanwhile overestimating the benefit all together.
