I would have attempted a controlled crash over gentle mountainous terrain like this. You want to dump the aircraft's kinetic energy rapidly but not suddenly -- gliding into the side of a cliff will kill you, but keeping the airplane pointed forward while shearing off the wheels and crumpling the nose is fine. It looked like there were several areas where this would have been relatively safe to attempt. You don't need a nice flat field for a survivable crash.

After you're on the ground, you also need to be able to survive (possibly for days), and then be visible enough to be found and rescued. Staying with the aircraft is usually considered the safer approach, both for visibility as well as the emergency gear that you're supposed to be carrying in the back.

The only terrain where I'd seriously consider bailing out (assuming I had a parachute) is dense forest with no clearings. Surviving a crash like this is incredibly difficult -- you hit a redwood, shear off your wings, and then plummet 250 ft to your death. It'll be hard to spot the wreckage of a small plane from above. Even with a parachute, there's a serious risk of getting stuck in a tree (or impaled by branches). There are basically no good options here.

In short, mountains aren't so bad. But be super careful flying over forests. If this video was a stunt, there's a reason why he decided to stage it over mountains rather than a forest.

One thing in these comments I haven't seen said: F*K that plane. Off runway landing has significant risk. Parachute is so close to 0.0 risk that you do it just for fun on a day off. I wouldn't do an off runway landing just for fun on my day off.

The thing is staged, no question. The guy knows he messed up and will pay for it. But if I had to decide between my life and protecting a bunch of metal tubes and (fabric | aluminium, not sure), I know what I would do.

The whole thing looks planned, but if I were in the same situation I’d definitely be jumping over trying to crash land a cheap plane in a riverbed or clearing.

This sounds pretty scary though… If you were an experienced skydiver, with your gear on, don’t you think you’d be tempted to jump instead?

Experienced sky divers get to choose their jump points and landing sites. They don’t get thrown out of the plane at an arbitrary time with no preselected landing side.

You would controlled crash the plane because you would know that jumping over mountainous terrain with vegetation is a great way to break a bone which is going to make getting the heck out of there really, really suck.

A plane like pictured is going to stall at like 40mph so that will be your approximate crash speed, which is really damn survivable in an aircraft with a 4pt belt to keep you off the hard bits of the cabin.

Risk of some bruising and maybe a concussion beats risk of broken ankle any day.

It's not so cut and dry as you might think.

> But if it was me in that plane and I saw a 10% risk of serious bodily harm / death in trying to land and a 0.1% risk in jumping, it would be tempting to jump.

I think your intuition is wildly off base w.r.t. the risks of general aviation and sky diving.

If you exclude experimental aircraft like fighter jets and kit builds, general aviation isn't much more dangerous than riding a motorcycle. The leading causes of death are misjudging the weather and miscalculating fuel because most of a pilot's training isn't in how to fly a plane but how to troubleshoot it midair or land safely if that is impossible.

An unplanned skydive in a mountainous area in Southern California during Santa Ana season? Now, that's risky. (Edit) For perspective, Nevada sky diving companies won't even jump over Black rock desert because of the wind and that's a desert so big and flat that it's used for amateur rocketry in the 100k+ feet range.

Sure, but now we’re talking about a situation where your engine has already failed… That’s very different.

What to do on engine failure is one of the first things they teach you after basic flight lessons. After that many instructors will even simulate surprise engine failure by cutting off the engine at random while the student is trying to learn about some other emergency situation. Engine failure is part of the check rides every pilot needs to pass to get a license.

When the engine stops working because it doesn't get enough fuel because there's nothing left in the tanks, the root cause is not putting enough fuel in the tanks, not engine failure.

Here https://news.ycombinator.com/item?id=29731719 it seems like you are essentially saying "engine failure is not too dangerous; one of the leading causes of death is running out of fuel".

I did not say running out of fuel should be formally classified as an engine failure. It was more that I supposed that the effect on the airworthiness of their airplane should be approximately the same whether the engine stops due to failure or running out of fuel. So that makes your comment appear contradictory. Hence my prompting for an explanation, I'm quite willing to believe I misunderstood something of your post or about aviation so I didn't intend for it to sound glib.

I think it's pretty obvious this was staged and he very carefully chose the landing spot.

Of course. Point is, risk does not actually turn that way. Parachuting into rocks is not exactly safe and easy either! Vast majority of pilots are much more trained to safely land than to safely parachute. Movies give us this idea that you pull a cord and land feather like. That is empathically not the case. Especially for an untrained person, parachuting on safe ground will break your limbs virtually guaranteed.

Small airplanes have very low stall speed. If you fly into the wind you can have your land / crash speed very low and very controlled, you are trained to find best possible spot, and are buckled inside metal chassis.

I genuinely believe most licensed pilots would stay inside the damn plane :)

So if the person is an experienced skydiver, doesn't the equation change towards ditching the plane?

Mind you, no one is arguing whether the video is real or not, that's conclusive that it's likely fake. But what if an experience skydiver was actually in this situation?

Its also important to remember that wilderness does not mean people are not there, so if you do something stupid thinking noones around so noone can get hurt, you might still hurt someone.

And just because people aren't directly in the path of a falling plane doesn't mean that the pilot isn't putting people's lives at risk. The recent rains have improved the situation a bit, but a plane crash in the remote mountains of Southern California? That's how you get wildfires.

I think he should still follow the procedure far further than showed in video (where he doesn't follow ANY), and I still feel he should have tried far harder to find a landing spot - cessna 152 has 11 to 1 glide ratio, which means for every foot of altitude you can travel 11 feet of distance. I imagine his airplane has roughly comparable gliding distance so given his original height, he had a LOT of time and options he seemed to have immediately squandered. At best, assuming reality, that feels like a yahoo parachuter rather than methodical pilot, and not advice / approach to follow.

if skydiver has a pilots license he will always prefer to try to land it, unless the wings broke off

While I have never flown a plane nor parachuted, my understanding is that the maneuverability options of both are going to be roughly equivalent, so that either option will have roughly the same ability to choose the site of collision and (for small aircraft) even roughly the same speed at collision. And that makes the choice down to having a layer of metal that can absorb some of the impact for your versus having to be in the exactly correct position to absorb the impact energy best with your body.
