WHY TURBULENCE IS TERRIFYING

I was on a flight from Denver to Atlanta last year when the plane dropped. Not a gentle dip. A genuine, cabin-rattling, drinks-airborne, stomach-leaving-the-body drop that lasted maybe two seconds and felt like ten. The flight attendant who had been pouring tomato juice when it started was wearing most of it by the time it stopped. A man across the aisle from me made a noise I have never heard another human make. I gripped the armrest hard enough that my hand cramped. We then continued our flight, landed safely, and everyone disembarked like nothing had happened.

The wing did not snap. The plane was not in danger. The pilots did not even mention it. According to the captain, who I asked at the gate because I am the kind of person who does that, what I had just experienced was "moderate turbulence" and was completely routine. The 737 I was sitting in was certified to handle forces several times worse than what we hit, and the wings would flex up to twenty-something feet before structural failure was even on the table. None of this stopped me from feeling like I had just escaped death.

This is the central weirdness of turbulence. The aircraft is fine. The passengers are not.

The brain wasn't built for this

Humans evolved to walk on solid ground. Our entire balance system, the vestibular apparatus in the inner ear, exists to tell us when we are upright and when we are about to fall over. It is exquisitely sensitive to vertical acceleration because falling out of a tree was historically a survival problem worth solving. When that system detects sudden downward motion, it sends a primal alarm to the rest of the brain. Falling. Doing something about it. Right now.

Turbulence triggers exactly this alarm. The plane drops a few feet because of a pocket of less dense air, and your inner ear registers the same signal it would if you had stepped off a cliff. The cognitive part of your brain knows you are in a metal tube full of seatbelt-wearing strangers thirty thousand feet above Nebraska. The vestibular part does not care. It is screaming. The cognitive part eventually wins, but not before your adrenal glands have dumped enough cortisol to make you remember the moment forever.

This is why turbulence feels so much worse than it is. Your brain is not measuring the forces involved. It is measuring how strongly the falling alarm is firing. A plane dropping six feet at low frequency feels catastrophic even though six feet is nothing. A plane shaking continuously for ten minutes at high frequency feels merely annoying even though it is doing more total work on your body. The brain rates fear by surprise, not by magnitude.

Loss of control is the multiplier

There is a body of research on what makes humans afraid of things, and one of the most consistent findings is that perceived control changes everything. Driving a car at seventy miles an hour with bad weather and tired eyes is statistically more dangerous than sitting on a commercial flight in a thunderstorm. Almost nobody is afraid of the first situation and millions of people are terrified of the second. The difference is the steering wheel.

When you are driving, you can react. You can slow down. You can pull over. You can choose your lane and your speed and your route. Even when those choices are illusory, even when the truck behind you is going to do whatever it does regardless, you feel like you have agency. On a plane you have no agency. You cannot see what the pilots see. You cannot influence the aircraft in any way. You cannot even open the window. Your survival is entirely in the hands of strangers and machinery, and your brain finds this unacceptable.

Turbulence amplifies this. When the cabin shakes, you cannot do anything about it. There is no action available to you that improves your situation. You can grip the armrest, which does nothing. You can pray, which empirically does nothing for your turbulence outcomes. You can close your eyes, which actually makes it worse because removing visual cues makes the vestibular system more confused. The combination of high physiological alarm and zero available action is, neurologically, one of the worst situations you can put a human brain in. It is the same combination that makes things like enclosed spaces and being held underwater so primal-fear-inducing. Turbulence is claustrophobia and falling and helplessness, all at once, with peanuts.

The history that haunts every passenger

The other reason turbulence feels lethal is that there are real incidents that suggest it can be. Not many, but enough that anyone who has ever read a Wikipedia rabbit hole about aviation knows the names.

Air France 447 went down in 2009 in the middle of the Atlantic. The proximate cause was iced-over pitot tubes giving the pilots bad airspeed data, but the precipitating event was severe turbulence at the edge of a thunderstorm cell. The pilots were flying through weather they did not fully understand, the plane stalled, and the recovery was botched in ways that took years to fully reconstruct. Two hundred and twenty-eight people died. Every aviation enthusiast knows the cockpit voice recorder transcript. It is not a comforting document.

JAL 123 in 1985 is even worse to read about. A faulty repair to the rear pressure bulkhead failed at altitude, blowing off the vertical stabilizer and severing all four hydraulic lines. The pilots flew a basically uncontrollable 747 for thirty-two minutes using only differential engine thrust before crashing into a mountain. Five hundred and twenty people died. Some passengers wrote farewell notes during those thirty-two minutes. Turbulence had nothing to do with it, but the imagery of a plane that cannot be controlled by its pilots is part of the cultural background of every flight you take, whether you know the specific incident or not.

More recently, the Singapore Airlines flight from London to Singapore in 2024 hit clear-air turbulence so severe that one passenger died of a heart attack and dozens were seriously injured. Clear-air turbulence is the scariest kind because there is no warning. No clouds, no storm, no visible reason. The plane just suddenly drops. Reports said the aircraft fell about a hundred and seventy feet in a few seconds. People who were not wearing seatbelts hit the ceiling. The cabin looked like a crime scene afterward. Pictures circulated. Everyone who flies regularly saw them.

These incidents are statistically rare. Commercial aviation is one of the safest forms of transportation ever invented. Your odds of dying on any given flight are something like one in eleven million. You are far more likely to die driving to the airport than flying from it. None of this matters when the cabin starts shaking, because your brain is not running a Bayesian probability calculation. It is running a pattern match on every plane crash story it has ever heard, and finding plenty of matches.

Why pilots are not scared

Here is the thing that should be reassuring and somehow never is. Pilots are not afraid of turbulence. They find it annoying, the way you find a pothole annoying when you are driving. It is uncomfortable and it might spill the coffee but it is not a threat. Pilots actively try to fly around the worst of it because they want their passengers to be comfortable, not because the plane is in danger.

Aircraft are designed to flex. The wings of a 787 can deflect more than twenty-six feet at the tips before they hit their certification limit, and the actual structural failure point is significantly higher. Boeing famously tested wing flex by literally bending the wings until they broke during certification, and the breaking point was so far beyond anything a real flight would encounter that the test was basically theatrical. The plane is not going to come apart in turbulence. It cannot, mechanically.

What pilots are slightly worried about during turbulence is not the airframe. It is the unbelted passengers in the back, the carts in the aisles, the laptops on tray tables, and the cabin crew. People get hurt in turbulence. The plane does not. This is why the seatbelt sign exists and why you should actually obey it even when nothing is happening, because the worst turbulence is the kind nobody saw coming.

How games make this fun

Here is where it gets interesting for me. Real turbulence is one of the worst sensory experiences available to a human. Game turbulence is one of the best. The same physical event that makes my actual hands sweat when I am sitting in 14C is delightful when I am the one flying.

The reason is the agency thing. When you are the pilot in a flight game, turbulence becomes a problem to solve. The plane gets bumped and you correct. The wind shifts and you adjust the trim. The approach gets choppy and you fight it down. Every input you make changes the outcome. The same vestibular signals that would terrify you as a passenger become information you act on. The brain reads the situation differently because the body has agency.

This is something the realistic flight sims like Microsoft Flight Simulator have figured out. They model turbulence with a lot of detail because it is part of what makes flying interesting. A perfectly smooth approach is boring. A bumpy approach where you have to fight the controls is engaging. The game is more fun when the air is not cooperating because the act of overcoming it feels meaningful. I wrote about this dynamic in plane landing games, where the unpredictability of the final thirty seconds is exactly what makes them worth playing again and again.

Arcade flight games take this further by exaggerating turbulence into pure spectacle. The plane gets thrown around like a pinball and you are laughing because the stakes are entirely fictional. The sensory experience that would be hell on a real flight is transformed into entertainment, because you are in control and the only thing on the line is your high score.

What we did with This Is Your Captain

Working on This Is Your Captain forced us to think about turbulence in a really specific way. The game is about being a pilot whose plane is constantly being beaten by physics, and turbulence is one of the core mechanics. We had a long internal debate about how scary to make it.

The realistic option was to model turbulence accurately. Subtle bumps most of the time, occasional drops that genuinely surprise the player, the slow buildup of dread when the weather radar starts showing red. This is what a serious sim would do, and it would be authentic. It would also be no fun, because the entire point of our game is comedy. Nobody wants to load up a comedic flight game and have a real anxiety attack about a six-foot drop in the cabin.

The other option was to make turbulence theatrical. The plane shakes wildly. The passengers scream. Things fly around the cabin in absurd ways. Coffee cups orbit the cockpit. The entire thing is dialed up to a level that real turbulence never reaches, because the goal is not to recreate the experience of being on a plane. The goal is to recreate the cartoon version of being on a plane, where every problem is hilariously oversized and every solution is ridiculous. We went with this version, obviously. Comedy turbulence beats authentic turbulence every time when your game is supposed to make people laugh.

The trick is that this exaggerated turbulence is actually closer to how real turbulence feels than realistic turbulence would be. Because the way your brain processes a turbulent flight in real life is exactly this cartoonish. The plane is not really dropping ten feet. Your inner ear is telling you it is dropping a hundred. The cabin is not really upside down. It feels like it is. Comedy turbulence is honest in the sense that it matches the felt experience even when it does not match the physical reality. You watch a passenger fly out of their seat in our game and laugh, and that laughter is partly recognition. Yes, that is what it felt like the last time the seatbelt sign came on without warning.

The thing about fear

Fear of turbulence is mostly fear of dying, and fear of dying is something that evolution gave us for excellent reasons. The problem is that the system is calibrated for falling out of trees, not for sitting in a metal tube while it encounters minor atmospheric variation. Our hardware is too sensitive for the environment we now operate in. There is no upgrade path.

What helps, if you are someone who is afraid of turbulence, is understanding the gap between what your body is telling you and what is actually happening. Knowing that the wings flex like that on purpose, that the pilots are not concerned, that even the worst recorded turbulence has not brought down a modern airliner, that the bumps you feel are typically a fraction of the forces the plane is rated for. This knowledge does not eliminate the fear. The vestibular system does not negotiate with cognition. But it can shrink the fear from "I am going to die" to "this is unpleasant," and that shrinkage is meaningful.

What also helps is making it funny. Reframe the cabin shake as a roller coaster. Reframe the drop as a free sample of zero gravity. Reframe the captain's casual announcement about expected chop as the setup to a sitcom. Anything that interrupts the falling alarm with a different cognitive frame can take the edge off, because the alarm relies on you treating the situation as serious. If you treat it as a bit, the bit competes with the panic.

This is part of what we wanted to do with the game. Flying is genuinely amazing. The fact that humans can sit in a chair eight kilometers in the air and complain about the wifi is one of the most absurd technical achievements in our species' history. Turbulence is the moment when the absurdity becomes visible, when the illusion of normal life cracks and you remember you are doing something impossible. The terror and the comedy are two responses to the same recognition. We just chose the comedy one.

The next time the cabin starts shaking, try this. Imagine the wing is made of rubber. Imagine the pilots are mildly bored. Imagine the whole thing as a slapstick scene where everyone ends up covered in tomato juice and walks off fine. It will not eliminate the fear. But it might let you sit with it. The plane is going to do what the plane does. The only thing you actually control up there is the story you tell yourself, and a funnier story is almost always a better one to be inside.
