My Dad (retired air force) also forwarded this to me, which I found pretty interesting. One of the 'features' of the X-29[1] demonstrator (which was exploring dynamically unstable flight) was that it continued to fly in all sorts of 'outside the envelope' scenarios.

The part that amazes me though is that any human being can sit there and figure out that adding thrust or doing some other action helps or doesn't help when sitting in a chunk of steel that wants to hit the ground hard. I have total respect for folks who stay stone cold rational in the face of their imminent demise.

The thing is, it just sort of happens. It's not some massive effort to remain calm, but rather you just automatically focus. That's how people have described it, and it's been my own experience. I've never experienced anything close to this bad, but I've had a couple of aeronautical close scrapes and there's just no room for fear.

Edit: had the same experience in a car once as well. Total focus on solving the problem. Terror comes after.


I'm a (private) pilot. Many years ago, I faced a sudden engine failure and performed an emergency landing in a minuscule pasture surrounded by a very forested area. It very nearly costed me and my passengers' lives.

The plane was without engine for several minutes before I landed, yet that time was spent fully engrossed and completely focused on the problem. I had clarity of thought like nothing I've ever experienced.

No emotions — no fear, nothing — just stone cold rationality. Going through the checklist, Mayday call, considering options, etc. with swift and decisive precision.

Though I believe the extensive training certainly helped, to this day I'm amazed at the incredible stress response our body has evolved. Even though it happened many years ago, I still think about it a lot.


My instructor explained and trained me to simply focus on flying the parts you have left and don't let the parts that are missing bother you too much, they are gone and can't help anyway.


The people who panicked when under massive stress probably got eaten at a higher rate.


Or more to the point, they're not left to post on HN.

It'd be interesting to at least hear from the ones that totally freaked out and made it anyway.


Forethought (visualization) and training play a big part as well.

You reminded me of something that happened to me while driving a few years ago. I was on the highway in the far left lane going about 70mph. I was driving an Audi A4, which had much better (sensitive) handling than the pickup truck I was used to driving. There was a breakdown lane to the left of me (unusual for most highways) and I thought to myself, "if I suddenly needed to swerve out of the way for some reason, I could flick my wrist and get into the left breakdown lane to avoid whatever was happening in front of me".

Not more than a few seconds after having that thought, I saw the car in front of the car in front of me jump up onto the car in front of it. The car in front of me slammed on his brakes. I flicked my wrist to the left without thinking. Only when I passed (in the left breakdown lane) all the cars piled on top of each other did I realize just how closely I dodged a serious accident. If I had not visualized what I would do in such a scenario a few seconds earlier, I'm not sure if I would've done the same thing.


Good driving involves always being aware of safe exits if you need to make an evasive maneuver. It's a habit that comes well in handy as you say.


And safe following distances.


Plenty of close calls have taught me the value of always knowing my exits and always leaving plenty of space between me and the car in front of me (driving instructors often teach 1 car length for every 10 mph: 70 mph = 7 car lengths).

Unfortunately a lot of these rules only work if other drivers on the road are also following them (around here, in the Boston area, you'll be lucky to have 2 car lengths of space in front of you no matter your speed), so I've learned that simply being aware at all times (no phone, no distracting conversations, and holy hell no text messaging or emails) is the best thing anyone can do for improving their safety while behind the wheel.


This is what they used to call "defensive driving".

Supposedly, people who think through how they would handle emergencies or other bad situations handle them much better than people who don't like to think about it. This is true even when it's a situation they hadn't actually planned through yet, because they have the mental habit of solving problems rationally rather than just pretending they won't happen.


I've saved my car from rear ending the one in front using exactly that manoeuvre - escaping onto the gravel between the fast lane and the central reservation.

I now leave a lot more space between me and the car in front, and I've trained myself to remember that traffic might stop dead at any time.


My guess is that the first car was doing something odd, some tiny instability that caused the second car to change, say momentarily lifting their foot from the accelerator, etc. Your higher brain functions were doing an executive analysis of options, but your lizard brain was already alert to danger and had sounded the early alarm. Have you ever noticed how you are extremely sensitive to tiny sideways movements of cars as you pass them?


Couldn't upvote Mike's comment enough. It all comes down to good training, and methodical thinking - something that's generally ingrained in you with aviation.

As a skydiving instructor, I've had 3 parachute malfunctions that required cutting away & deploying my reserve. Each time something goes wrong, everything else goes out of focus: you have a problem to solve. You first assess the situation and work to regain control - as long as you have altitude, you have room to work & get creative. When you reach a certain "decision altitude" - or determine there's no way you'll be able to land the parachute safely - you make the decision that you'd do better with a different parachute. And you enact emergency procedures.

Beauty of it is, good training makes this automatic. It gives you a decision tree to work off of. IMO, the same sort of decision tree is an excellent thing to think about when crisis planning for companies. But that's another story.


I think there might be a bit of Survivorship Bias going on here... the people who fail to become calm and focused aren't around to tell us about it.

The term you're looking for is "natural selection". No, seriously, that's exactly how it works.


That's an excellent point. However, I don't think it accounts for all of it. There are lots of cases where people can panic and still survive. It lowers the odds, but doesn't reduce them to zero.
