I'm such a wimp. All you folks falling 20-40 feet with no or minor injuries...I tore tendons off my ankle in a 10 ft. fall and it's never been the same. Are you the same folks doing 20 ft. dyno's? :P

If you are having ideas about practising your landing skills in case you fall unexpectedly, I would hate to desillusion you, but you do not have much time to react and little possibility.
I am surprised no one has brought Ms. Lynn famous fall into a tree. From the top of my head, it was 30m fall (forgot to tie-in) with a broken leg maximum injury.
From myself, I fell 14m from the top of my gym (forgot to tie-in) onto a wooden floor. I got numerous spine fractures including lifethreatening C2 vertebrae split, and 2 rather messed up wrists. This is probably because I sort of attempted to sit in my harness when I reached the top of the route.
14m free fall with initial speed 0 will take over a second but less than 2.
(unless mistaken).
What is your reaction time ??

Uncontrolled falls from 12 feet or greater yeild an 85% chance of death. Uncontrolled being the key word. Most falls climbing are controlled in some fashion, or at least slightly anticipated so some control was maintained, and bouldering you have spotters. Breaking holds would probably be the worst fall, know that one from experience, only my hold broke off 6 feet down the wall resulting in a 400 pound boulder following me to the ground. I suspect divine intervention is to blame for my survival. That rock should have crushed me easy!

In reply to: Sounds like a poster child for the pro-helmet lobby...I heard on the news yesterday of a little girl that was ejected from the vehicle in an automobile accident. She went on to fly over the guard rail of the overpass they were on and landed on the pavement 40 ft. below. She survived with a ruptured spleen, punctured lung and fractured orbital (eye-bone)....a miracle if you ask me!
Trajectory plays a key roll in this survival. She was probably traveling at 50+ over the guard rail and likey closer to 35-40 when she hit the ground which is more of a glancing blow instead of a solid one. I am sure the speed involved assisted in her survival.

In reply to: I'm an EMT and had to respond for a guy who fell 4m, He was pronounced brain dead at the hosital after we flew him in. He died 2 days later. So I don't think that you have to fall far you just have to land right. |

According to the Army, a parachutist should be able to survive a fall from 35' if utilizing proper pararchute landing fall (PLF) techinque. Naturally, this is a controlled fall where the feet and knees are together, and body properly posistioned for impact with the ground, balls of the feet first and then crumpling up and rolling.
So learn how to PLF just in case.

In reply to: For the record, I mentioned up-thread that one reaches terminal velocity quickly, at less than 100'. That was from memory, and it was quite wrong. Assuming I set the diffeq up right (and I think I did), with a terminal velocity in the area of 120 miles/an hour (195 Km/hr, 54 m/s), at around 140 feet (40 m) you are at 50% terminal velocity, and at around 800 feet (240 m), you are at 90% terminal velocity. These are only rough, as one can change their air resistance quite easily depending upon the way they fall, and the drag coefficient stuff is only an approximation anyway (albeit a good one at low speed). So I was way wrong. Apparently terminal velocity is only interesting for skydivers, and that energies much lower than those of terminal velocity are quite lethal.
If you drop out the drag stuff (which makes the math easier, but makes the results less accurate) for all intents and purposes any fall from more than about 500 feet will have about the same energy to be dissipated when you hit the ground. I couldn't get the diffeq to set up right (its been a while) but I know how it should look vs. how it actually works.

Ok... i was watching pbs the other day, like a year ago, and there was some guy in a F16 or something and it fucked up. The dude ejected and the parachute didn't open. But come to find out he was in a mountainous territory and there was like 10 fee of snow on the ground. Well he skidded down one of the mountains and only broke both his legs. Not sure how high he was or what but it was some fall... i wonder what he was thinking on the way down... "god i hope i only break ONE leg"... lol
Well another camp story with this one. We had to watch a movie about some guy almost die'n to freak us out when we were doing the ropes stuff. Well come to find out that every foot you fall you have that much of a chance of die'n, so if you fall one foot you have 1% chance of die'n... they didn't say anything about how you fell or anything just the "every foot fallen = % of u die'n". If i'm wrong don't yell that's just what i heard.

That makes the russian stewardess story all the more impressive. She didn't cheat death once, she cheated it 300 times! :P

yeah... all i have to say is if somebody fell 30,000 feet and fell on an ant hill and lived... that was one big ass ant hill man. I'm not try'n to mess with u man but damn.... if i fell 30 feet i'm sure it would hurt like hell... and if you times that by 1000 you get hurt like hell times 1000... i would be dead. Was the ant hill on flat ground or what?... more info.
Did the woman live to walk or is she just goo on a bed? B/C i'm sure she broke ever bone in her body

mmm. After about six seconds into a fall the areodynamic force acting upwards equals the force of gravity. Rough numbers, of course, but an average person (involved in this study) will fall at about 60m/s or 135mph maximum
So after you fall for six seconds or (roughly) 263 meters or 960 feet, you will not accelerate any more. so 1,000 feet or 90,000 feet won't make much difference except for you not being able to breath ;)

My roomate likes to sky dive and he told me that if you freefall and hit the ground the body will bounce 4 feet in the air....my roomate is always saying 'catch ya on the bounce' as i am climbing. what a turd

hmm i odn't think how far you fall or how you land when you hit the ground matters much. i mean my daddy threw me up in the air like 15ft and dropped my in the parking lot on the way down and i turned out just fine. it all depends on how hard your head is. haha and i turned out just fine in case you were wondering :?

Ha ha! Flyingsquirrel you remind me of the SNL skit where Joe Montana goes through a whole opening monologue, looks blank for a moment, and then starts it all over again... "Hi, I'm Joe Montana.." (this just after major injury).

So if i fell 10Feet and landed on my feet i think i would be ok... what about falling 10 feet and landing on my head... i don't know about you but i think it matters how far and how you land. I'd rather break my leg than my head.
What if this guy landed on his head? U think he would have gotten up?

Yea...but you can't get rid of the drag stuff...when skydiving, in a belly down position, you reach terminal velocity at 120-130 mph. And that happens in the first 1000 feet of your freefall. If you go head down, you can reach speeds well over 200 mph.

I had a pretty good ground fall while boulbering recently, I fell from about 10 feet up onto a pile of rocks. Even though I landed bad (on my side wrapped around a boulder) I only got some scrapes on my leg and wrist. I think that when falling it is more a matter of luck that you land in a way that doesn't mess you up over deliberatly trying land in a certain spot or way. Don't get me wrong when you fall you will instinctivly try to land better- its a matter if you have enough good karma
