How high do you have to jump to make sure there's zero chances of survival?

[LastDayOnEarth]

I heard someone surviving a 9 stories fall so I'm curious, what's the minimum distance for a fall to be to ensure instant death and no chances to be brought back ?. Since where I live there aren't many tall buildings that I have access to, just wondering

Nothing will ever have a 0.00000000....% survival rate. The universe doesn't work like that, the human body doesn't work like that. People have fallen from airplanes without a parachute and survived. People have shot themselves in the face with a shotgun and survived.

Let's not call anything 100% foolproof. Let's say 99.9%. I think the height mentioned is 250 feet, or 76 meters, or so. Someone else can correct me if I'm wrong. Also, would you be impacting hard surface or water? *Might* make a difference depending on how you impact. If you impact water in a "tight" little configuration, feet first, you may survive, at least initially. It's hard to discount strange things happening.

From the source GeoStone:
150 ft (46m) or higher on land, and 250 ft (76m) over water, is 95-98% fatal. 150 ft / 46 m equates to roughly 10-15 stories of a building, depending on the height of one story. 250 ft is the height of the Golden State bridge.
(transcribed from an image I found here.)

It's always important to consider the surface and possible obstructions. Many factors come into play in jumping.

When looking on case studies of jumping/falling we find case of small distance that's fatal and also case of unusually high fall that's survived.

When I consider jumping as a method I consider factors that may increase success. For example, I consider jumping over water often. Wearing a weighted vest would increase chances of drowning, if the fall isn't fatal.

The impact surface would be a very important. The person falling from the airplane surviving was rare and it included an airplane seat that acted like a whirlygig and landing into a soft canopy of trees. Concrete.

Partner of a friend still in Intensive Care in Hospital after jumping from 240 feet here in Scotland, landing on rocky foreshore. Two broken legs, double spine fracture, load of other injuries. Going to be paraplegic from waist down, anticipated hospitalised for next 10-12 months.
Nothing is certain.

Hot air balloon jump would be ideal.

I know about a girl who jumped from 10 stories, landed on the concrete roof of a ground floor building and still survived. Instead of dying she got multiple broken bones and is most likely paralyzed now

You know, at or near terminal velocity, even water acts as a near "solid" surface. You're right, though, in that, even over concrete itself, if your body is "spread out" in just the right way, or if, maybe, you catch an updraft of some sort, there's always a chance, albeit a slight one, of surviving what should be a lethal fall. Freaky things can and do happen.

That is the issue with jumping, you can try your best with the hight and landing surface but there are parameters that aren't under your control so you can't insure success and the aftermath of surviving a jump is the worest thing that could happen to an already tormented person.

 

[Cagliostro]

falling from 500 meters is quite safe on the rock with a speed of 200km/h

Just cruel that they're still alive

But you could basically say this about anything. Even guns, which many would say are the quickest and most secure way to CTB, have their issues. If yr SI gets the best of you and you flitch or move in a way at the last minute, you could shoot yourself in a way that doesn't end things but leaves you in a lot of pain and with permanent health issues. Not trying to deter anyone just say nothing is 100 percent or without its flaws.

Yes nothing is a certain 100 percent but you can weigh how much of the variables you can control to some extent like you can better control where to shoot for success more than you can control how your body ends up landing that would guarantee death...

 

[Forveleth]

Rule of thumb here is 150ft/46m onto concrete and 250ft/76m onto water. However as stated above people can miraculously survive that. Yet there are people who land just right and die falling 3 feet off a ladder. It's more about the landing and luck than anything else.

That's a fair point.
