The Skydog Report

Saturday April 7, 2012 and pilots are anxious to try out the new gliders and they get going at 8 am again but by 9 am the wind is too strong again so towing is stopped. Bobby and I noticed that our Canadian friends are heading to Quest for the day so we pack up my T-2 and head out for Quest Air. We are set up by 3 pm and another pilot has taken off and gone XC and late we find out that he has landed at Wallaby Ranch. I get Mark Frutiger to haul me up and on my first attempt the weak link breaks at 400 feet high so I land in the strong winds and take another tow to 2,500 feet and search for lift.

Re: Why I don't like Wallaby Ranch

I support Joe for his coming out about the ranch. I too have had a similar experience and think Quest is waaaayyyyy cooler. At Quest they wont leave you in your cart and shut down the flight line for lunch. Or charge you 20 dollars for a broken weak link. Or not allow you to do Tandoms even though your a freaken Tandom Instructor. But I do still buy there T-shirts. Wallaby's T-shirts are waaaayyyy cooler then Quests.
I one hundred percent guarantee you that if those assholes had:

- figured out the difference between a weak link and a release;
- modified their goddam Dragonflies to the point at which they'd be up to the job they're supposed to be doing;
- used safe midrange weak links - 250 pound bridle end - on the gliders; and
- fined gliders five hundred bucks for anything that blew in anything short of a lockout

then Zack Marzec would still be around making cute hang gliding videos and being a friend to every pilot he met - except, of course, for the ones trying to get the rest of our problems fixed.

But, of course, this is hang gliding and the only thing that it loves doing more than rewarding mainstream incompetence and mediocrity is attacking and punishing competence and innovation.

If anyone needs a dose of frustration just post something about weaklinks.
...or helmets, or keel-grabbers, or the Aussie method, or bottle-grip vs grape-vine, or global warming, or...
...evolution, age of the planet, physics, grade school arithmetic...

Fuck off.

I would be more than happy to answer any questions pertaining to what I saw and experienced, but I prefer not to engage in speculation at this point.
Davis Straub - 2013/02/09 05:38:41 UTC

The glider pitched up.
The glider stalled.
A standard 130 pound test weak link was being used.
The weak link broke.
So what?
Davis Straub - 2013/02/09 16:45:39 UTC

I can't see how the weaklink has anything to do with this accident.
Davis Straub - 2013/02/09 17:45:21 UTC

I have no idea of the circumstances he faced.
Jim Rooney - 2013/02/09 18:30:26 UTC

Please continue with the speculation.
Kinsley Sykes - 2013/02/09 23:49:42 UTC

The reason for the vehemence of the response is they pile on to any AT accident, with no knowledge of the cause, and trot out the, if only he had a strong weaklink, nothing would have happened.
Paul Hurless - 2013/02/10 05:47:51 UTC

In general, no, I don't think that a weak link break is a big deal. In the case of the incident in Florida, I wasn't there to see it and I don't know all the details. I can't honestly make any claims about what happened and neither can anyone else who wasn't there. Blaming equipment failure or any other cause from only the limited information posted instead of firsthand knowledge is B.S.
Jim Rooney - 2013/02/12 18:00:27 UTC

I just buried my friend and you want me to have a nice little discussion about pure speculation about his accident so that some dude that's got a pet project wants to push his theories?

Deltaman loves his mouth release.
BFD

I get tired as hell "refuting" all these mouth release and "strong link" arguments. Dig through the forums if you want that. I've been doing it for years but unfortunately the peddlers are religious in their beliefs so they find justification any way they can to "prove" their stuff. This is known as "Confirmation Bias"... seeking data to support your theory... it's back-asswards. Guess what? The shit doesn't work. If it did, we'd be using it everywhere. But it doesn't stand the test of reality.

AT isn't new. This stuff's been worked on and worked over for years and thousands upon thousands of tows. I love all these egomaniacs that jump up and decide that they're going to "fix" things, as if no one else has ever thought of this stuff?

But back to the root of my anger... speculation.
Davis Straub - 2013/02/13 15:45:22 UTC

We have no agreement that a stronger weaklink would make it safer (again, I fly with a slightly stronger weaklink).
Jim Rooney - 2013/02/13 19:09:33 UTC

The shit works. It works in reality and it works consistently. It's not perfect, but Joe-Blow's pet theories have a very high bar to reach before they are given credence.

Jim Rooney - 2011/09/02 19:41:27 UTC

yes, there were other factors there as well

Why is the devil always in the fine print, and incidentally in the things people *don't* say.

Yes, go read that incident report.
Please note that the weaklink *saved* her ass. She still piled into the earth despite the weaklink helping her... for the same reason it had to help... lack of towing ability. She sat on the cart, like so many people insist on doing, and took to the air at Mach 5.
That never goes well.
Yet people insist on doing it.

Your tandem incident was some guy trying to drag himself out of a low lockout instead of accepting the fact that he was too far out of position and hitting the damn release, pulling the nose in and flying away.

Those "other factors" just happen to be *the* factors.
You can't look *for* facts to backup your opinion.
That's just bs arguing.

You have to look at facts and find what they tell you.
It doesn't work the other way around.

Any experience with Wallaby Ranch / Florida Ridge?
paicolman - 2013/02/22 09:37:44 UTC

I have a small question. We're planning to go to Florida in April/May for two weeks, visit some relatives, they are near Palm Beach.

Now I saw in google maps that Wallaby Ranch would be the nearest flight park there, so wanted to ask you guys if you have been there and how it is.
Questions like this are best posed to people no longer around to answer them. If you're just talking to survivors you're gonna get responses biased to the point of total uselessness.
I have zero experience in towing...
Then if you're planning on getting training anywhere in Florida - or, for that matter, the rest of the US - you're more qualified now than you will ever be again.
...all my flights have been mountain flights until now, so I'm curious how fast /slow can you learn to be able to do at least one solo flight?
If I knew how much experience Zack Marzec had I could probably give you some hard numbers on how much flight park experience you'd need to be able to solo more or less safely.
I don't think I can spend more than two to three days at the park, would that be too little time?
No, I think that would be two to three days too MUCH time. And I'm totally one hundred percent serious about that, dude.

If I isolated you from AT culture and forced you to develop your own equipment there's NO WAY IN HELL you'd come up with the crap they're gonna put you on and brainwash you into believing is acceptable.

And the reason for that is that all of the equipment in widespread use was developed by tug drivers - not hang glider pilots. And they don't give flying fucks about our safety.
(Edit: I just realized, the Florida Ridge would be even nearer, which one would you prefer?)
Get in touch with Antoine in one of your next door neighbor countries, Zack in Houston, or Joe Street in Ontario. I'd send you to Mike in the UK but he's gotta comply with...

Mike Lake - 2012/08/25 16:50:19 UTC

On the 12th August a new(ish) pilot took off on tow, his weak-link snapped, the glider's nose dropped and with no height to recover he hit the ground.

Now you can dress this incident up as much as you like but what put the guy in hospital was his 'safety device'.
If the weak-link had held he would have had a post flight briefing instead of a trip in a helicopter.

It is true the guy made some mistakes and was not a perfect pilot.
The weak-link sure taught him a lesson, perhaps we should also have given him a good kicking while he was on the ground waiting for the air ambulance.

A stronger weak-link, by that I mean one not teetering on the edge breaking under normal flight conditions, would drastically reduce the above risk.
This, the same risk we all (with current thinking) subject ourselves to on EVERY take off as we fly through the "Cone of Danger"
(smartarse comment acknowledged).

Now, this same guy in all probability will go through his whole flying career without suffering a lockout, he may well experience the onset of a lockout and of course release, as we are all trained to do.

At this onset why would the guy (with a stronger link) wait for his weak-link to break instead of releasing?
If he does wait he can be just as upside down with a weaker link than one that has given him the luxury of a reduced risk on every takeoff he has ever made.

One day we will look back and wonder why we endure this unnecessary risk at such a critical time, just like we now look back and wonder why we thought towing from the middle of the base bar was such a good idea, 'cos that's how everyone does it.
...BHPA's very stringent safety regulations.

Depending on the person, you could quite easily be solo in one day.
If you know how to fly, you could quite easily solo in one flight - which is the way ALL of us started aerotowing before these motherfuckers found better ways to commercialize the sport and screw over the hang glider pilot.
I did five tandem tows and the fifth one was a simulated weak link break at 100 feet.
Dude! Too bad Zack Marzec missed that part of the training! I mean if you can do a hundred feet no problem on your VERY FIRST TRY... He'd have had NO PROBLEM WHATSOEVER recovering from half again that high.
I did the five tandems and two or three solos in two days and I was a very fresh H2.
And, of course, they don't bog you down with any of that tedious "theory" crap so the training is nothing but nonstop fun!
Wallaby and The Ridge are both excellent flight parks.
Yeah, sure. Just ask them.

And Wallaby's got the safest weak links on the planet!
The Wallaby Ranch Aerotowing Primer for Experienced Pilots - 1998/02

A weak link connects the V-pull to the release, providing a safe limit on the tow force. If you fail to maintain the correct tow position (centered, with the wheels of the tug on the horizon), the weak link will break before you can get into too much trouble.
And in Wallaby's special little parcel of Central Florida air...
- Remember: it is almost impossible to stall under aerotow. The induced thrust vector makes the glider trim at a higher attitude. It is OK to push way out; you will climb, not stall.
...it's almost impossible to stall under aerotow. The induced thrust vector makes the glider trim at a higher attitude. It is OK to push way out; you will climb, not stall. AND the weak link will break before you can get into too much trouble.

Don't forget Quest Air.
How could we possibly forget Quest Air!
Another wonderful place to learn and practice AT.
No serious incidents in almost twenty days! And Zack was still alive when they drove him off in the ambulance so, technically, it really wasn't all THAT serious an incident. And not even that much damage to that glider.
They also have ET. Electric tow, which is a great aid to learning...
Paul Edwards - 2012/10/17 15:41:42 UTC

I thought the crash was over... I honestly did. Then my face hit the dirt and the weight and momentum of my body behind it squashed my right eye socket into the ground.

At the end of the day, I had some nice bruises around my eye and several fractures in my nose. It took about three days for my nose to stop bleeding altogether.
Stay High
Yeah. Really hard to overemphasize that last point.
Dan Lukaszewicz - 2013/02/22 12:52:53 UTC

Once you know how to fly learning to aero tow be come quickly. I did four to five tandems followed by five solo flights on a Falcon 195 with landing gear. Then I flew a couple of flights on my Sport 2 to learn how to come out of a dolly. There was also a written test, but that may have been a Lookout Mountain Flight Park requirement.
Any questions about the best way to safety a hook knife to your harness so you don't lose it while you're dealing with jammed release in a low level lockout?
I was able to complete training in two days.
It's amazing how efficiently they can teach you everything you need to know about this game.
It's possible to finish in a single day, but that would really be rushing it.
And then you'll have a couple of little letters on your card you can use to tell Tad to go fuck himself.

Speedy recovery to the pilot in question.
It could have been worse. It could have happened at...the other place (but nothing happens there. Image) Image Good luck if it does. No 911 calls allowed. My friend was lucky, the nurse on hand convinced the owner not to move him, this after he snatched and threw her phone away. Image She was trying to dial 911. My friend suffered lower back injury.
Sure.
You can stay at the Ranch and tow every day starting at 8 am.
And make sure you have somebody stationed a safe distance from launch with a cell phone with a fully charged battery.

I looked back to see the tug circle around and saw a wing turned up in a WHACK configuration. I was like "wow". Then I noticed it wasn't the tandem but Sherb-Air's Falcon 170.

When I got there her nose was lacerated and her lip was bleeding (yeah, she had a full face helmet) and the dolly's left wheel was missing.

The radiography showed acute multiple fractures around the top and head of the humerus. Her nose didn't break but she may have hairline fractures to the septum. She had a hard time remembering the date, day, names of her kids, number of kids, and other basic things...

The dolly had hit a huge hole and she went left shoulder into the ground at 25+ mph.
...and their weak links are GUARANTEED to meet your meet your expectations of breaking as early as possible in lockout situations...

...but being strong and reliable enough to avoid frequent breaks from turbulence.

In fucking credible.
- A highly experienced Advanced rated tandem AT instructor buys the farm on takeoff at Quest less than three weeks ago.
- According to all the goddam professional operators the reason for the crash is totally inexplicable.
- The Jack Show thread on the incident has been dead as a doornail for over nine days now.

And everybody's carrying on like ABSOLUTELY NOTHING HAS HAPPENED.

Kai-Martin Knaak - 2013/02/22 20:22:55 UTC

I tried, but got no response.
And you think that's unusual on a hang gliding forum?
So I'll try again..

The coroner identified injuries to the head as primary cause of death.
The coroner is an asshole. The primary cause of death was a chintzy little loop of fishing line that tens of thousands of total morons have been using for decades as the focal points of their safe towing systems.
The link at the top of this thread also notes, that the deceased wore a helmet.
Obvious conclusion: Don't wear a helmet.
Obvious questions:

Did the helmet fail?
- Nope. The helmet absorbed exactly the amount of energy it was designed to. And then Zack's skull and brain picked up from that point and took care of the excess.

- Speaking of things FAILING... Is there anything else that failed on this one that we could discuss for a minute or two? Just kidding.
Was the impact so violent that no helmet whatsoever would have helped?
I dunno. Let's keep flying Rooney Links and compare what happens to people wearing different types of helmets.
Or was it a type of impact that the helmet simply was not designed for? (Read, face first with an open face helmet)
"Excuse me for a moment. I fly hang gliders out of Quest and use a Rooney Link to increase the safety of the towing operation. What helmet do you recommend for best protection in a tumble from 150 feet in the two to three hundred dollar range? Preferably in blue."
Did the shell of the helmet break, so that the protective foam could do its job to absorb the shock?
Yeah. You always wanna get the shell to break so that the protective foam can do its job. Try to come down on a paved runway or in a narrow dry riverbed with large rocks strewn all over the place.
Did the helmet receive a deadly blow by the nose of the glider?
- No.
- Who the fuck cares?
Answers to these questions may influence my decisions when shopping for protective flight gear.
What kind of fishing line will you be shopping for? 130 pound Cortland Greenspot braided Dacron trolling line? Hard to go wrong with a proven system that works.

I can't see how the weaklink has anything to do with this accident.
Because it's one of those crusty old debates that HGs love to go round and round with.
Yeah, all us subhuman HG dolts just inherently lack the Keen Intellects necessary to really comprehend issues like weak links, releases, and pro toads.
It's like uttering the word "wheels"... the conversation instantly turns into the great wheel debate.
Which is totally ridiculous because this hang glider landing issue is so clear-cut, simple, easy. I mean, you've already written volumes on this and it's absolutely dumbfounding why everybody can't get it and stop crashing, breaking arms, and ripping shoulders apart.
Sorry for the interruption.
No, that's OK. It's always an honor and a privilege for us to hear anything you have to say on any issue.
Please continue with the speculation.
Couldn't you please just clear it up for us? There are actually a few people beginning to think that his Rooney Link might have had some significance here - and that's TOTALLY ridiculous because the Rooney Link is a proven system that works and has a track record quite literally HUNDREDS of THOUSANDS of tows long.
I'll be over here, doing something productive.
So have you finished jerking off yet? I'm assuming that's what you're talking about 'cause that's about the only thing I can think of that should take priority over getting to some kind of conclusion about why this skygod buddy of yours launched on a so-so thermal afternoon and was DOA a short time later at the hospital.

Look at who we've got here:

Paul and Lauren Tjaden, Gerry Grossnegger, Marc Fink, Davis Straub, Jim Rooney, Mark Frutiger, Bart Weghorst, William Olive, Jim Gaar, Bill Cummings, Brad Gryder, Quinn Cromwell...

Tow park operators, eminently qualified tandem pilots, hang gliding forum administrators, tow manual editors, safety officers, world record holders, keen intellectuals, tug pilots, eyewitnesses, test pilots, towing pioneers, frozen slush experts...

Where else are ya gonna find that much talent and expertise all in one place? And yet we don't seem to be able to reach ANY kind of explanation or viable hypothesis regarding what the critical issues were here.

Yeah, we were going pretty fast, it was pretty dark, there were lotsa icebergs floating around, we rubbed up against one a little bit... But who's to really say?

This is all just baseless speculation from the kinds of trolls who come out of the woodwork when something like this happens and use it to say "See, this proves our point. If people would just reduce speed at night when they get reports of ice fields ahead we'd average much better outcomes. In fact if you look at the available data you'll see that there is no record of anyone who's slowed to twelve knots having a similar problem."

This, in spite of not having been there and only having second hand information to make this point. If you believe that fine, knock yourself out, but don't use BS like "This wouldn't have happened if only you had listened to me."

I have zero respect for those who are using a tragedy to push their twisted agendas, particularly when there is no proven link between their points and this accident.

So here we are, a wee bit short of three weeks later, no closer to a viable explanation, and the conversation is shifting as it ALWAYS DOES to the best kind of lifejacket to use for plunging into freezing ocean waters when the ship goes down in some kind of freak accident that no one can ever explain - let alone predict or prevent.

And I'm wondering this, Jim...

Ditto dude.

It always amazes to hear know it all pilots arguing with the professional pilots.
I mean seriously, this is our job.
We do more tows in a day than they do in a month (year for most).

We *might* have an idea of how this stuff works.
They *might* do well to listen.
Not that they will, mind you... cuz they *know*.

I mean seriously... ridgerodent's going to inform me as to what Kroop has to say on this? Seriously? Steve's a good friend of mine. I've worked at Quest with him. We've had this discussion ... IN PERSON. And many other ones that get misunderstood by the general public. It's laughable.

Don't even get me started on Tad. That obnoxious blow hard has gotten himself banned from every flying site that he used to visit... he doesn't fly anymore... because he has no where to fly. His theories were annoying at best and downright dangerous most of the time. Good riddance.

So, argue all you like.
I don't care.
I've been through all these arguments a million times... this is my job.
I could be more political about it, but screw it... I'm not in the mood to put up with tender sensibilities... Some weekend warrior isn't about to inform me about jack sh*t when it comes to towing. I've got thousands upon thousands of tows under my belt. I don't know everything, but I'll wager the house that I've got it sussed a bit better than an armchair warrior.
If you professional tug pilot motherfuckers are so goddam good at sussing out this standard aerotow weak link issue how come y'all so totally suck at getting ANY of the back end guys to understand it? Could it be, perhaps, that they're the ones getting crashed, injured, killed while you're starting your turns back to the runways?
