Assuming uniform acceleration after impact, how many g's did the guy pull? Let distance equal 6 ft.

No, your not him. I reviewed your posts. I fell at rocky butte once, nearly met Jesus myself, and a dude named Peter was there. It was by silver bullet bluff. If you at the circuit look for the kinda short dude w/ riduculously small feet- thats me.

Batten, how about time it took from impact until fully stopped on head? I have a feeling you could figger this out.

Ah.

I was thinking of heading to Smith this weekend, but it still looks like it's going to be snowing. I've had some great winter days down there before, but I'm undecided if I want to deal with camping/climbing if it's going to be miserable out.

Looks kinda crappy, but I need to get out, just for one day.

Sorry for the semi-thread hijack folks, now, how fast was the bible going when when it realized it took too much acid and was really a person?

It is impossible that guy survived that kind of fall. It is a Hoax! In 6ft. No !@#$%^& way!

"fearless under the umbrella of Jesus' protection..."

Yes, maybe? I would never test like this or put someone on the spot like this.

Juan, whats an approximate terminal velocity for a skier?

Werner, do you happen to be a man of faith?

Do you care to elaborate? How about everyone else here? What are your "beliefs"?

If that guy really lived, its a true miracle!

Jesus was a Buddha, you pray his name in times of danger and it will help you.

When I get into trouble on the rock I start praying to Jesus right away.

He has always saved me in time of danger.

This is what the lord REALLY thinks of Jamie and his Cliff Huck for Christ:

Rock!...oopsie.

Sorry to disappoint you Werner, and you too hobo. Thanks for the challenge, but this idiot won't be stepping up for the cliff jump. Chalk it up to a lack of "faith" (proudly guilty), or lack of balls (not so proudly guilty), or maybe just too much common sense (I like to think so). I prefer to keep my risks a bit more calculated than our skier friend, but I still say ski it out or it don't count.

Did you read more about his jump? Sounds about as calculated as a jump could be. I remember a while ago he was talking about this cliff, waiting for snow conditions to be perfect. I guess they were, cuz he landed on the back of his face and hes ok.

I talked to Paul Ahern after he did the 225 foot jump. He said as soon as he was in the air it was way more than he expected or wanted and after he hit he said never again. I didn't expect anyone to top it for a long time.

I've made a 6 foot crater off much smaller cliffs, I can't imagine the impact of that jump. He was very lucky to screw up the landing and still walk away.

P.S. I've jumped off the Golden Gate, It was a very spiritual experience.

If he was accelerating at 1g for 245 feet, then he would have had to deaccelerate at 245/6 = about 40g (average) to come to a stop in 6 feet. 40g isn't all that bad - he could walk away from this no problem, especially with Jesus helping, hah.

Climbers should understand this. Assume a dynamic rope stretches 10% (a preety stretchy rope, but throw in a dynamic belay and it's not unreasonable). In a factor 2 fall the climber will "experience" 20g of deceleration. For example you fall 200 feet at 1g on 100 feet of rope, and then decelerate at 20g to rest as the rope stretches 10 feet.

The scary part isn't the deceleration, it's that the anchor or last piece of pro sees 20 times your body weight as you decelerate. If you weigh 200 pounds better hope that those bolts can take 4000 pounds. Carabiners rated for 20kN will be just about at their limit.

Peter,

Check those numbers again... a rope will have dynamic/elongation properties up to around 35%, not 10% under that scenario.

I don't think there is any way you can load a piece to 4K with a body and a fall but I'm away from my cocktail napkin and pencil at the moment.

Yea Russ, I thought those were really weird numbers too. Ed H were are you?

Doesn't your back break way before those numbers that Peter said occur?

All the Engineers and Physicists are in bed resting their big brains. Just us real world guys out here on the night shift calling BS with precious little gray matter to back it up.
