IIRC takeoff and landing are the most dangerous parts, so I'd be more interested fatalities per trip. An intercontinental plane ride would cover more miles than I drive in a year which makes the per mile stat meaningless to me. I think it would still be in the plane's favor but probably not as significantly. And in that case if you're a safe driver (healthy adult, doesn't drink or do drugs, doesn't speed, etc) it might skew in favor of driving since I'm sure some groups are much higher risk.
If you are a terrible driver, you can certainly make your individual odds of accident a lot worse than the average case, but I'm not sure being a good driver improves your odds by that much. A lot of the risks are totally out of the driver's control (e.g., other road users, equipment, weather etc..).
Choice of weather conditions is within your control, just don't drive in terrible weather.
Being a good driver does a ton to insulate you from the shenanigans of
Equipment failure is basically a rounding errors but also within the driver's control since "flat tire at speed" is probably lion's share of crashes in that category.
Bad weather is certainly a factor in a lot of General Aviation accidents. VFR into IMC (Visual Flight Rules, ie you fly by looking where you're going; into Instrument Meteorological Conditions, ie you can't see very far due to low cloud or nightfall) kills a bunch of people every year. Some of those killed are IFR rated. In theory they know how to fly a plane when you can't see where you're going, but theory and practice are different.
One thing that's different between GA and driving is that you could stop driving. An hour from home, realising that the road really is too treacherous, you could pull over and walk. Up in the sky they don't have that option at a moment's notice. But one thing that's exactly the same is mission mindset - people fixate on what they intended to do until after it's far too late rather than have contingency plans.
Eh? It's absolutely an option, from a technical weather forecasting perspective, to see that a storm exists, and to abort a particular plane flight before it takes off, or reroute to another airport. This happens all the time in extreme weather conditions (eg winter anywhere it snowstorms). That airlines choose not to more proactively cancel flights in moderately inclement weather is a business decision, not a shortcoming of our weather forecasting abilities. Flights often get delayed by weather at the other end - it's jarring to hear the pilot say the flight you're on is delayed due to heavy rain at your destination, when it's a gorgeous sunny day in your current location, but it happens quite frequently!
The comment you're responding to is talking about general aviation, small propeller planes. Those have a relatively high incident count for flying into bad weather. When the pilot is only trained to fly visually (VFR) and enters low visibility or clouds they're very likely to crash.
This isn't a problem in airline flights. There are very specific rules about when you can and cannot depart and when an alternate airport and fuel for it is required. No airline takes off without satisfying all the rules and almost no airline cancels a flight for weather while the rules say it could go.
This is a nice summary. VFR into IMC and pilot task saturation/distraction are such killers in the broad GA space. Literally forgetting the fly/operate the plane.
Not always within your control (pandemic notwithstanding). Sometimes you have to catch a train, commute into work, etc., and "the weather is bad" is not always a valid excuse.
I remember hearing with the rise of regional airlines starting in the 90s the number of flight cycles (takeoffs/landings) went way up for some types of planes...and I assume for the "average flight." An increase in the number of short trips would make lowing the per-mile rating more impressive.
The stat is doubly misleading because it is skewed by the proliferation of long direct flights as turbofan widebody jets proliferated and air travel became more affordable which both happened in the same time period as that chart.
I don't think flying is particularly dangerous but the person you're replying to is being highly naive or misleading by taking that chart at face value.
Hmm, after looking at that, and always being told that airlines are the safest. I was surprised they are only safest by that one metric (fatalities / distance) and not fatalities per trip or fatalities per hour.
I have personally never liked being blankly told that flying is safer than driving, because I’d like to understand how safe flying is versus driving when something goes wrong.
Two seconds of inattention in a car is a lot more likely to kill you than it is in a plane. It’s fairly constant risk - going off the shoulder is just a few dozen feet at most.
They also tend to be less well maintained, and the other participants less trained.
That makes sense at first glance, but it's something I'm in control of. I was even thinking of this before, because the comparison is a little mismatched. I'm 100% likely to be a passenger when I'm in any plane, whereas I'm probably >98% likely to be a driver when I'm in a car.
I'm not sure why I was downvoted, because I'm just stating I'd like to understand (data/studies) instead of people's anecdotes and opinions, including my own.
My intuition is that car travel has a constant level of risk, whereas plane travel has a level of risk much below that when everything is good but (I'm guessing here) that risk goes much higher than the constant risk of car travel when something goes wrong (failure, human mistake, crash, birds, weather, etc.). I've searched for it before and didn't find anything, but it'd be nice to see any studies that confirm or deny this.
My father always said that accidents tend to happen when two people make mistakes. Even when fault technically lies with a single party, it's often the case that both parties had a chance to prevent the mistake from becoming a collision.
For example, if a turning vehicle cuts off oncoming traffic, it could get hit. An attentive driver in the oncoming lane might see the problem and hit the brakes, while an inattentive or speeding driver might not react in time. The turning vehicle is at fault, but that doesn't mean they were the only one that could have prevented the collision.
There are sometimes events you cannot control, but a lot of those multi-vehicle collisions were preventable by either party.
When you are in a plane there is a 100% probability that the driver will be a trained professional, while according to your stats there is less than a 2% chance that your driver will be a trained professional when you are in a car.
While I have no hard stats I would also assume that a plane is much safer when something goes wrong. Why?
1) Professional 'driver' who has trained for years to handle risks and failure scenarios and practices these on a regular basis.
2) Redundancy and graceful failure is designed into many of the components and systems on a plane, while cars tend towards the cheapest component or system possible unless mandated by law.
3) Space (both altitude and the fact that the sky is basically empty) provides time to solve some problems before they become catastrophic failures and makes other classes of problems very unlikely.
If you blow a tire, run into a deer, or have a transmission failure while you are cruising down the highway at 80mph you have seconds (at most) to react and respond. If a plane hits birds, has an engine fail, or loses some other system they usually have minutes to troubleshoot the problem and redundant systems that prevent the plane from just falling out of the sky.

When they happen all you do it move over and come to a stop. Unless you go Full Redditor(TM) and start adding a bunch of extreme control inputs none of these things are that bad. They don't require much reaction at all even if you are paralyzed by indecision it can still turn out fine since all you have to do is stop.
Blowouts are a non-event, IMO, just a flat tire with an extra audio alert.
Automatic transmissions basically don't fail in unsafe ways. Worst case you'll find some extra neutrals and make an ass out of yourself failing to merge or something. Splitting the case on a manual (like you might do if you go for 4th and somehow find 2nd, or jump a vehicle and don't mash the clutch before hitting the ground) is surprisingly uneventful from a maintaining control perspective.
Deer suck, mostly because they tend to break a bunch of expensive cosmetic bits.
Having a hood fly up on you is worse than any of the above events because you can't see. Brake failure kinda sucks too, especially with an automatic trans.
Things “go wrong” fairly “frequently” on airplanes but they are hardened for this with redundant systems and manual (as well as computer) overrides. You don’t hear about most of them but they are all logged and used for improvements.
The main difference is when a car has a catastrophic failure there’s a good chance the people involved survive.
I suppose by wrong I mean something more than the redundant, robust, and various protection systems can handle. For example, on a car, I wouldn't consider the anti-lock brake system kicking in as something going wrong.
I've had an engine failure in my car while driving it. I simply was able to slow to a crawl until I got home. I don't think engine failure on an airplane is such an anti-climatic event, on average.
> I don't think engine failure on an airplane is such an anti-climatic event, on average.
It often is, actually. They have more than one engine precisely for that scenario, and can fly quite well with one down. Flights over water are also carefully planned based on distance to the nearest airport with an engine out.
Engine failure on a modern airplane is quite anti-climatic. We train for it regularly, and there are standard procedures to follow after the failure. Basically secure the failed engine, if it's just after takeoff climb to a safe altitude (sometimes following a predetermined route) using the other engine, then select a runway for landing and land almost normally.
What you probably really want to compare flying and driving is fatalities per trip--for the same trip. As others have noted, a longer trip in a plane is almost certainly safer per mile than a shorter trip given where accidents happen. (And the effect may or may not be further magnified by the fact that I assume the accident rate is higher on small regional jets. Though, on the other hand, they carry fewer people.) On the other hand, driving is probably much more proportional to distance.
If my goal is "I wish to spend X hours in a form of transit", sure. If I need to get from LA to NYC, though... there's a lot more of those 5 minute periods if I'm driving.
