Again what he wrote was generalized blather. No numbers, no specifics other than you need a weak link of "sufficient" strength. He did not assign a defined number to "sufficient". The only specificity he made was a mention of Quest. I know you do not like Quest or this fellow and that is coloring your argument.
Tad wrote:He's got seven seconds of airtime remaining as things progressed. He had enough energy left to get it pointed back in something resembling the original intended direction, level, and stopped but he needed to get everything he owned all the way to the left and stuff the bar immediately.

Any disagreement?
Yep, There is a crosswind in the area where he hit the tree. It is very possible that when he pulled in, the glider flew across the lz because it was pointed into the wind. Pulling in hard to the left may have produced a stall and fall. Pulling in and getting the glider flying, then making a gradual turn to split the difference would have worked better.
Tad wrote:He actually didn't do all that bad as it was and I've personally witnessed much worse in a lot of LZs twenty times more forgiving than that one. And I'm willing to say that if his instruction had been better he coulda brought that glider down on that strip in the same conditions and done just fine.
Watching a few of the n00bs land, I got the feeling that the club did not indoctrinate the n00bs on how to land. This pilot walked the lz with a visiting pilot who flies McClure a few times a year. The lz looks deceptively easy when walked. From the air, it is down hill except for the very end. Beyond the end, from the air, you can see the electric lines, and brush covered hillocks. It is intimidating for a first timer from the bay area. Then there are the cross winds. The club instructs the locals on aircraft approaches and on 180° approaches. They are taught to keep speed up and keep the bar pulled in for the whole approach. The n00bs did none of this.

I am going to mention this and see what transpired.
miguel wrote:Earlier on, there was another pilot who hit the trees in the same spot and did not come out. He was ok, do not know about the glider.
Tad wrote:In more than one of these videos shot from the McClure breakdown area I'm hearing in the voices of the people near the camera anxiety when the glider is setting up for final and relief - sometimes premature - when it appears that the landing is in the bag. That tells me that the overall landing skills and procedures for this strip are inadequate.
Again, there are occasional turbulent crosswinds in the lz that are not apparent until you get hit by one.

Most locals know this and react accordingly. Low time pilots and occasional pilots have to learn. What you see is a learning experience. There used to be tall trees on the windward side of the lz. There were usually severe rotors rolling through the lz. That is how I learned. The trees were cut a few years back so now the rotors are diminished but there are still crosswind gusts.
miguel wrote:The point is that he hit the ground prone with very serious consequences.
Tad wrote:No.

The point is that he got EXTREMELY / DANGEROUSLY slow when very low on approach and stalled the crap out of the glider at thirty feet.

And for the purposes of this forum in general and this thread in particular there is NOTHING to be learned from this one.

I've told you repeatedly that I have virtually no interest in discussions about the best ways to crash a glider. They're distractions from valuable discussions about the best ways to NOT crash a glider.

And the best way to NOT crash a glider on landing is to stay prone and on the basetube for as long as possible for the given set of circumstances.

And the best way to NOT crash a glider on takeoff is to tell the Wallaby, Quest, Florida Ridge, Lookout, Currituck, Manquin, Ridgely, Cloud 9, Whitewater, Cowboy Up standard aerotow weak link shitheads to go fuck themselves.
Image

You have constantly made the point that prone landings are safer for what ever reason. As an exercise, you can fill in the blanks with your reasons:

1.)
2.)
3.)

I gave this as an example of a consequence of a bad prone landing. Not every landing is going to be a greaser at the Mellow Meadows lz, like you imply. There is no sense pretending that it will. Reality sucks sometimes.
miguel wrote:It had enough resolution to where it could zoom up on the glider and pilot.
Tad wrote:And that wasn't an important enough seventeen seconds in McClure history to merit the full rez upload?
I know who owns the full video and I am not sure he had the blessings of the pilot to post it on youtube. If the pilot involved does not want to share, so be it.
miguel wrote:I saw no pilot effort to fly or control the glider.
Tad wrote:Bingo! THAT'S the point.
miguel wrote:That is very unlike the pilot.
Tad wrote:Try this...

1. He was tired, overheated, dehydrated, airsick, whatever and not clicking on all cylinders.
2. He drifted into the approach WAY low.
3. But his brain was hardwired for the usual touchdown area - in no small part due to this sport's pathological obsession with spots.
All that can be said of this video is that the pilot came in too slow, stalled, dropped a wing, turned and crashed. The pilot did not make much effort to fly the glider. The pilot hit the ground in the prone position. The pilot was severely injured.

All the rest are unsupported, somewhat worthless suppositions.
Tad wrote:Got any thoughts about how to turn anything around in the keeping-gliders-under-better-control department?
At McClure, it used to be, when you did the wrong thing, you got a stern lecture on what, where, why and how. That does not happen any more. Some people were offended by the process. Now it is a happy party and most people get by and are happy.
Zack wrote:This'll be good... :mrgreen:
Tad wrote:Sorry Zack, we currently have 223 posts here on the "Weak links" thread and - given that none of that has sunk in at all yet - a short tantrum is all I have energy for at the moment. Maybe something better down the road a bit.
Please take it to the Weak Link thread. I will probably never again tow a hg and have no interest in it.

I will argue for developement of both upright and prone flight and landing skills until you ban me or until someone takes my keyboard away. :mrgreen:

Post by Tad Eareckson »

Again what he wrote was generalized blather.
What's your point? Is generalized blather less likely to kill someone than specialized blather?
No numbers...
1. BULLSHIT. He says "Quest Air links". And everyone and his dog knows that means a single loop of 130 pound Greenspot. And those of us capable of understanding and doing numbers can plug that into equations and tell what's going on.

2. Not that that really matters anyway 'cause what's WAY more important than numbers is...
Larry West - 2012/02/20 14:49:54 UTC

He was connecting his paraglider tow bridle to his harness (Z5) shoulder loops and I thought that was weird, and asked him about it. He told me "that's how I towed all week" so I asked him if he was going to tow with it over or under his basetube and he replied "I did both and it doesn't make any difference."

This scared me, so I asked him how much theory Mark taught, and my buddy said "None. We just flew a lot." I laughed and said "That's cool, but they had you take a written test, didn't they?" and he got mad (he was already stressing) and said "Larry, we just flew and those guys said I was flying like a Hang 3.", at which point I just walked away and waited for something bad to happen... which it did five minutes later.
...THEORY.

3. And THIS:
Tost Flugzeuggerätebau

Weak links protect your aircraft against overloading.
is all the theory there is to weak links. Anything different, more, or less is crap.

4. And the first thing out of George's idiot mouth is:
The weak link is NOT there to prevent the glider from being overstressed on tow.
5. Once you understand the theory the numbers are pretty easy and have to do with how much loading the gliders are designed to take and the maximum loading under which they're expected to operate.
...no specifics other than you need a weak link of "sufficient" strength...
1. You DON'T "NEED" a weak link. The hang and para gliding situations in which a weak link is NEEDED are virtually nonexistent. Saying you NEED a weak link for towing safety is a lot like saying you NEED a parachute for flying under two hundred feet. Its chances of doing you any good are just about zilch and the chances of you getting fucked up if it goes off at a random moment are pretty damn high.

2. I'd estimate the probability of a flight getting getting crashed, hurt, killed for want of wheels is EASILY a hundred thousand times as high as anything bad happening for want of an ACTUAL appropriate weak link - 1.5 to 2.0 Gs.

3. Likewise, the shit that George is referring to as a "REASONABLE weak link" - about three quarters of a G if you're lucky - is about a hundred thousand times more likely to fuck you up than flying without a weak link anywhere in the system.
I know you do not like Quest or this fellow and that is coloring your argument.
I DESPISE Quest (as should anyone else with half a brain or better and a shred or two of decency) but I'd actually rank George pretty close to the top of the stack amongst hang glider people. But dangerous irresponsible crap is dangerous irresponsible crap irrespective of the source.
Pulling in hard to the left may have produced a stall and fall.
He had plenty of energy when he came out of the tree and wasn't anywhere close to stalling. He could've thrown a lot more left into the equation and maintained a good margin.
Pulling in and getting the glider flying, then making a gradual turn to split the difference would have worked better.
I'm not arguing for much different. We're both trying to get him down on the grass and in something approaching the original intended direction. And it sounds like we're in agreement that it could've been done.

Also...

Given that he elected to let it fly into the scrub, that would've been a real good excuse to exercise the classic hang glider landing whipstall that gets so many arms broken in practice. Instead he just mushed it in and trashed a couple of downtubes.
Watching a few of the n00bs land, I got the feeling that the club did not indoctrinate the n00bs on how to land.
Is that the club's job? Isn't there supposed to be a Pilot Proficiency System training and rating people so they know how to handle situations before they get into them?
They are taught to keep speed up and keep the bar pulled in for the whole approach. The n00bs did none of this.
This one did. Maybe it would've helped if someone had also told him to practice higher speed flying at altitude before going into that mode down low where oscillation can have consequences.
Again, there are occasional turbulent crosswinds in the lz that are not apparent until you get hit by one.
1. So ya gotta get hit by one before you start figuring out what to do? You can't just come in assuming you WILL be hit by one?

2. So far I haven't seen any incidents in that strip attributable in the least to turbulent crosswinds.

3. I'm really not all that interested in hearing about turbulent crosswinds anyway. There's only so much you can do in a hang glider to compensate for them regardless of your skill level and if you keep coming down in conditions which can overwhelm your control authority you're rolling dice. And REAL pilots don't roll dice.
Low time pilots and occasional pilots have to learn. What you see is a learning experience.
THAT strip is obviously NOT the place to be LEARNING. The skills need to be solidly wired in at environments in which a C level performance won't get you crashed.
As an exercise, you can fill in the blanks with your reasons:
1) Superior control authority.
2) Superior control authority.
3) Superior control authority.
I gave this as an example of a consequence of a bad prone landing.
Yeah, well it's NOT. It's an example of somebody pulling in for more speed than he knows how to deal with and consequently losing control of the glider. You can use the superior control authority you have flying prone on the basetube to better keep yourself safe or, if you choose, more quickly kill yourself any way you can name other than a whipstall.

Videos of people getting creamed because they were upright are a dime a dozen. I'm still waiting to see ONE of somebody crashing because he was prone and needed to be upright.
Not every landing is going to be a greaser at the Mellow Meadows lz...
You mean places at which a wheel landing is simply out of the question? Like the McClure lower LZ?
I know who owns the full video and I am not sure he had the blessings of the pilot to post it on youtube.
Let's assume that's the case.

Fuck the pilot. He screwed the pooch and cost society the million bucks or so it took to put him back together. He should want us to have every scrap of evidence available to find out what happened and how to keep the same thing from happening to somebody else.

Also...

I'm really wondering what there could possibly be that he wouldn't want us to see in the high rez version and why he's OK with the fuzzed version.
If the pilot involved does not want to share, so be it.
It's not his to share. It was somebody else using his own camera to record on his own card on public land.
All the rest are unsupported, somewhat worthless suppositions.
1. I haven't represented anything as being supported.

2. I haven't supposed shit.

3. I've thrown out some ideas.

4. Somewhat worthless is another way of saying somewhat valuable.

5. So far my ideas are the best possible scenarios I've heard.

6. My ideas may all be completely off target but could still reduce the likelihood of someone else three quarters killing himself trying to come in on that strip.
Now it is a happy party and most people get by and are happy.
Yep. It never ceases to amaze me how happy people stay in a sport which kills one person per thousand per year.
Please take it to the Weak Link thread.
Did you read my previous post on this one?
I will probably never again tow a hg and have no interest in it.
That's totally fine with me. I will fight the Ugandans to the death to protect your right to not tow and have no interest in towing.

But with rights come responsibilities. And - on this forum anyway - you have a responsibility to not make insane endorsements of other people's insane statements. If you wanna do that you'll be welcomed with open arms by Davis Straub, Jack Axaopoulos, Bob Kuczewski, Sam Kellner, and Peter Birren - to name but a few.

I didn't introduce the topic of weak links here. You made the statement that:
...George is a wise man...
after I presented a post saturated with evidence of absolute lunacy.

I then presented another couple of posts equally saturated with lunacy as further undeniable evidence. And - although you state you don't tow and have no interest in flatlands aviation - you say that there's nothing really wrong with what he wrote when, in fact, the five or ten of us in the hang and para gliding population who understand what a weak link is know that there's virtually nothing right with it.
...I will argue for development of both upright and prone flight and landing skills...
Hang gliding doesn't need anyone arguing for the development of upright. It's been obsessed with upright and spots since the days of four to one. And that obsession has ruined, destroyed, and ended a lot of lives. And the obsession has been trending to the upper right in the 32 years since I started in it.
...until you ban me...
You know about how hard you hafta try to get banned outta here. But if you're gonna stake out positions I'd really appreciate it if you'd back up what you're saying with solid evidence.

Hello! I did some flights with my new U2... It is amazing "tool"... Image
Last time I landed on the wheels but, suddenly, right one got stuck into a hole...
Nose landing was the result and my head strongly hit the keel...
Wheel got stuck in a hole? Imagine that. The lz owner must not have gotten the memo commanding him to upgrade his lz to the standards of the Happy Acres ElZee.

You need to pick your shoe for the site you fly or your flying style. With that said I had a good landing one time and landed in a hole and twisted my ankle. It would have been much worse if i had not had my high top boots. And with that said I only wear them in the winter to keep the snow out and keep my feet dry.
...minus the hobbling around on crutches thing for a couple of weeks afterwards.

And then he planted the nose and got his head swung into the keel pretty hard.

No freakin' way something like that could happen to someone going for a foot landing.

Once again with wheels
Rich Jesuroga - 2008/05/19 17:49:23 UTC

A few years back a friend who had good landing skills missed ONE. Stuck his speed bar in the dirt and whacked hard. He swung through the control bar and hit the top of his helmet on the keel buckling his neck. He was a quadriplegic for eight months before committing suicide. Would wheels have worked? YES - no debate by those who were there and witnessed the accident.
If I've gotta do nik's landing in his place without knowing about the hole I'm gonna do it EXACTLY the same way. That way I know I'm not gonna bend or break a downtube, dent a keel, sprain or break an ankle, break an arm, dislocate a shoulder, suffer a concussion, or break my neck. Those are all distinct possibilities otherwise.
The lz owner must not have gotten the memo commanding him to upgrade his lz to the standards of the Happy Acres ElZee.

Upcoming shoulder surgery
Davis Straub - 2012/02/02 02:00:20 UTC

It was basically nothing. I was landing at a very small private abandoned air strip cut out from the cactus. I had the glider coming in fast in ground effect. Let out the bar to trim, then was running to unload the glider instead of flaring and I just tripped, fell out straight with my arms straight out and nothing happened at all but the sharp pain in my shoulder. The glider landed fine on its base bar.
...foot landing on the Happy Acres Airstrip or nik wheel landing at Prairie Dog Town and sticking one in a burrow?

OPs arm
Orion Price (OP) - 2012/05/20 17:58:25 UTC
San Fernando Valley

Great flight from McGee. 12k for some time. Cored a thermal with a gigantic eagle. 1:20 or so flight. Went downwind away from the lift once everyone else was on the ground and packed up.

Nice big field where one of the PGs landed first. Popped up during hand transition. Came down fast across the ground. A few steps, glider came over faster than I could run. Small wheels dug into the ground.

No ligament or joint injury. Just a clean downtube through the ol' humerus routine. Bone grinding against bone before immobilization was painful.

Not to be outdone by OP, I collided with the windsock pipe on landing Sunday. Result was a pretty nasty fracture of right humerus. Had surgery to put in a rod on Monday morning and as of Monday night am still at Holy Cross.

Doing fine, still don't have cast, but expecting to get discharged Tuesday or Wednesday. Thanks a ton to all the pilots who helped. Especially Caitlin and Kathy for the ride to the hospital. BTW Rob, they still have me in your sling.

OP's XC bad landings (stuck zipper, wind gradient)
Orion Price - 2012/04/26 21:24:07 UTC

Reading MikeL's story, I thought I'd add mine.

The stuck zipper and panic:

With about 300 AGL I went to unzip before staging a pattern above the airport. Pulling and pulling I found the zipper wouldn't budge. Cranking on the emergency velcro wasn't working either. In panic mode I tried to just kick through the zipper, no luck. Through all this, I wasn't flying the glider. Pulling on random parts of the harness I rocked back and forth losing more altitude. Pure panic, I wasn't thinking clearly. I couldn't foresee me panicking like this, but there I was. No organized thought, just fight or flight syndrome. Once I considered a belly landing, the panic left as suddenly as it came. With a clear head I thought out a good approach and had a smooth easy belly landing. Clothing stuck in the zipper was the culprit.

Moral of the story. Prepare for landing early. Practice using the velcro escape hatch.
No organized thought, just fight or flight syndrome.
Yeah. That trap has killed people in the situation in which you found yourself.
Once I considered a belly landing, the panic left as suddenly as it came.
Yeah. Amazing how quickly that works, isn't it? Give it a try sometime when you're not trapped in your pod and just nervous about the landing.
With a clear head I thought out a good approach and had a smooth easy belly landing.
Yeah.
Moral of the story...
So what asshole(s) signed you off on your Two and Three? Why weren't you trained not to turn a minor annoyance into a potentially lethal situation?
What asshole sold you your:
- glider?
- pod?
Wills Wing

A third principle to observe is that if you are using a "pod" type harness, you should unzip and confirm that your legs are free to exit the harness at least 500 feet above the ground and before you start your approach. If there is any problem finding the zipper pull, or dealing with a stuck zipper, you don't want to have to try to fix that problem while also flying the approach.
But since it's not possible to roll or belly a Wills Wing glider in under ANY circumstances - including the one of being trapped in a Wills Wing pod - you're not even gonna present that as an option in any of your owner's manuals, are ya?
Fuck you guys.
Wind gradient the next day:
With tired arms, that maybe didn't give the proper feed back, I turned to final approach. I thought I had a proper amount of speed, plenty of bar pressure indicating the glider's remaining energy. However about 30 feet above the ground all the bar pressure was suddenly lost. I pulled in as much as possible to regain pressure but I was too low. Dropping onto the tarmac I tried a flare. It was ineffective at slowing my vector down and into the earth. I got two steps on the ground before I couldn't keep up. Another, but less controlled, belly landing resulted. Harness, belt buckle, and shoes all took a mighty scrapping. No skin or down tubes were lost, luckily. Had this happened the previous day, with the stuck zipper, who knows what injury would have resulted. My chest would have taken the energy and not my legs. Had this happened over a boulder field... I don't want to continue talking about this subject.

Moral: A previous assumption of their being less gradient above smoother terrain could have been a deadly misunderstanding. When in the desert, stuff the bar on final.
With tired arms, that maybe didn't give the proper feed back...
Bullshit. You had the bottom drop out from underneath you.
Dropping onto the tarmac...
You couldn't find something that wasn't paved to land on?
Another, but less controlled, belly landing resulted.
Goddam right.
The day before you PLANNED and EXECUTED a belly landing and came out smelling like a rose.
This time you squandered what tiny reserve of energy you had on an ATTEMPT at a stupid useless foot landing and an UNcontrolled belly landing RESULTED - along with a lot more damage than you'd have had if you had made the right call and thrown in the towel immediately.
Had this happened the previous day, with the stuck zipper, who knows what injury would have resulted.
You'd have been better off because the stupid option would've been removed from the menu for you.
Had this happened over a boulder field...
You're not supposed to be landing planes in boulder fields, regardless of any pod issues or lack thereof, no matter what the testosterone poisoned assholes with whom you fly are telling you. If you land a glider in a boulder field once in a hang gliding career you're an idiot - hopefully a temporary/salvageable one. If you do it twice you're not a pilot and don't have any business participating in the sport regardless of how lucky you were or weren't.
When in the desert, stuff the bar on final.
It's hard to get in much trouble stuffing the bar at fifty feet no matter where you're coming in.

Time for a Tad style quizz :geek:

You are about to hit the pole. Do you:

a). hit the pole squarely, while prone because you have your Joe Faust approved neck support --->Image
b). hug that downtube and hit the pole while hugging the downtube.
c). continue chilling in the ez chair and TVing out with a couple cold ones.

d - I don't care.

I'm ONLY interested in strategies for not hitting poles. And my call is that if/when we get a good report we're gonna find that Mike:
- was coming into a very wheel friendly putting green;
- was in reasonably good control of the situation before he went upright;
- lost control of the situation upon and as a result of going upright; and
- would be flying next weekend with the same downtubes if he had stayed prone all the way in.

(Are there any other branches of aviation which put this much emphasis on the best ways to fly into windsock poles?)
