Nope.... This guy was working on a high rise sign when one of his employs moved the crane wrong and knocked him off...

Thats just so perfect.
Snipe, 4 ft. is a lot different than 23 ft.

That math is tenths of a second, pretty fast as far as I can calculate. Tuck and Roll, cool you just missed the fast part.

How much would it take to get you to leap off a 23 foot roof, videotape and show it?

We can get a fund going! I'm in for $10.

Try that as you are caught by surprise as you slip off the ladder or tree branch at 20'. You will not realize what happened until you are on the ground. That's just the way it is.
Sort of like when a minivan floors it mere feet away from you and you cant react in time because it's over too fast?

Oh wait, i did react in time. I was able to greatly reduce my injuries by getting partially out of the way because i did react in time. If i'd have reacted another tenth of a second faster, i probably would not have been hurt at all.

Or perhaps like the time i was rapelling and the D-ring hook on my web gear broke, and i fell at least 20 feet and was not hurt because i rolled (backwards) when i landed? (i'm sure it didn't hurt that i was wearing a K-pot and it was a sandy surface).

I posted links to numerous sites all recommending that you A) learn how to fall, and B) roll when you do, as it reduces the impact force by up to 30%.

But what do any of us know?

The guy in the minivan floored it from about 10 feet away from me (probably less). And i almost got out of the way in time.

But hey, it's not like i linked to 3 separate sporting sites stating that you should A) learn how to fall, and B) roll when you do.

NO? Then I think we can safely call this one: a lucky landing...

No need to get all worked up on this guys.

One can indeed train to absorb the impact of a high fall.
But even a trained commando with a ninja training background will need a certain amount of LUCK in order to just dust off his sleeve and walk away. (even from a mere 23 feet)
Knowing that my uncle is not a young, fit paratrooper, nor is he a ninja, I think it is safe to say he was lucky.

(at least we think so, it is looking good but we still don't have 100% confirmation that he will have no permanent injuries)
I agree with all this.

All i have said in this thread is that if you learn how to fall you MAY be able to greatly reduce the chance of injury.

Which is incomprehensible to some, apparently, even though i posted links to several disparate sporting sites that all said the exact same thing.

You're also heavily encumbered with gear which increases the KE of the landing greatly as opposed to a guy with no extra gear on, which is why i said it's the same approximate impact force, NOT the same impact velocity.

And of course if you have a partially screwed up canopy you can hit the ground REALLY hard. And if you do, rolling will, as the site i previously linked to stated, reduce the actual impact force by up to 30%

That's just a fact.

What you actually land on also has a huge "impact" (hehe) on how easy/hard it will be to avoid injury.

Bill,

While I don't disagree with your facts, it is probably too late for Geronimo's uncle to fall better last Friday.

Your premises and conclusions probably deserve a thread of their own.

Best,
Tom

It's all good.

I never meant to knock Geronimo's uncle, i was merely trying to inform those that may not be aware that by learning how to fall you can greatly reduce the risk of injury in some (not all) situations.

And i did not just offer an unsupported opinion, i linked to 3 different sporting sites that all backed up my claims.

People are certainly free to disagree, but it doesn't mean i'm not right. :-P

Truth is if there was no debate that sprang up here this thread would have been buried about an hour after it was first posted.

No worries guys, I appreciate everybody's comments and views on the matter. The monkey roll is a proven technique. Whether it is feasible while accidentally falling depends on many things. Knowing the technique is one thing, being able to execute it, is another. You guys getting all worked up is, well, nothing out of the ordinary...

Paratroopers are taught to bend at the knees as they land and roll.
Snipe, you know absolutely nothing about skydiving or sport parachuting and have never observed paratroop training.

Rot911 has it right. The only time you jump from higher than 4 feet to practice a PLF ("monkey roll", WTF?) is on the fan trainer - where the harness you're strapped into drives a bloody great fan to slow your descent.

The guys with 120 lbs packs DON'T LAND THEM - they let them out on a 40ft lanyard so they hit the ground significantly before they do.

Your ruck gets unfurled but your rifle, web gear, helmet, body armor, canteens, standard ammo loadout and chute are all still strapped to you- yes? And they weigh how much?

The term "monkey roll" is a kung fu martial arts term, so you may now consider yourself un-WTF'ed.

My sister was in the 101st Airborne and has her jump wings, by the way. I also served with several Paratroopers, as a whole lot of airborne trained soldiers actually go to leg units after airborne school. I however was never stupid enough to want to jump out of aircraft. Proud leg here.

I have no idea what sport parachuting has to do with anything, as i've not mentioned it at all.

I've never heard of a monkey roll per se in kung fu. There are monkey styles and rolls but it isn't a term of art in any style I've studied. For instance we had various monkey strikes and kicks, but a roll was just called a roll. A google search doesn't turn up much on it. I think you're referring to what is typically called a shoulder roll.

But *this* is a monkey roll:
