I'm not, as you may guess, of the opinion that "it's better to be on tow".
It's better to be off tow.

In this case, what is better ?

1-
When in doubt... get the hell off tow.
Get off before it gets scary.
Pretty simple stuff.
So, with a release not reliable for emergency, let a hand go, get worse, release if you have time enough ..and kill you

2- expect a blown weaklink
- Greenspot 130lb comes ..and kill you
- Greenspot 130lb never comes ..and kill you

3- stay on tow with a 1.4G weaklink and make the correction

Here, the solution:

I'd say that easing up on the gas was the right call but I'm not sure it made any difference in this situation.
That's always bothered me - I think I was wrong. I'm on the record now saying that gassing it would've been a better move.

Jim Rooney - 2007/07/22 22:30:28 UTC

I've heard it a million times before from comp pilots insisting on towing with even doubled up weaklinks (some want no weaklink). I tell them the same thing I'm telling you... suck it up. You're not the only one on the line. I didn't ask to be a test pilot. I can live with your inconvenience.

A 200 lb weak link is equivalent to two loops of 130. Either case is stronger than the tug's weak link. Did you change your mind? If so, why?
I'm not, as you may guess, of the opinion that "it's better to be on tow".
I'm not aware of anyone that would make such a blanket statement.

Did you change your mind about that too?
He doesn't have a mind. He just goes with whatever direction the most sewage is flowing at the moment.
My take is that sometimes it's better to be on tow and sometimes it's not - and a weak link lacks the ability to decide between the two situations.
What? You think you're a better pilot than a piece of Tournament grade Dacron trolling line? Get real.
I'm not sure what quote Freedomspyder was referring to, but perhaps it was this one:

I don't think this is always true either. Had Zack Marzec been given the rope instead of his weak link breaking the result would have been the same.
No.
Towing Aloft - 1998/01

Pro Tip: Always thank the tug pilot for intentionally releasing you, even if you feel you could have ridden it out. He should be given a vote of confidence that he made a good decision in the interest of your safety.
Being a pro - and, in fact, having been pro towed - he'd have been obligated to thank the tug pilot for intentionally releasing him, even if he felt he could have ridden it out. Mark should have been given a vote of confidence that he'd made a good decision in the interest of his safety.
Sure, being on tow at the wrong time is an extremely bad thing. But don't tell us that being off tow at the wrong time is all sweet and wonderful. Yes, we prepare for it, but that doesn't make it a safe situation. It makes it a manageable situation.
http://www.chgpa.org/forums/viewtopic.php?p=4411#p4411

I would say it's usually manageable - but in a few rare instances it isn't.
Yeah. Rare instances - like when you come off the cart.
Foot Launch - 2013/03/04 17:12:47 UTC

DeltaDude,

That vid is a payout tow with a pilot using a Koch release. In this case, I would say flying the wing was the best solution. It worked out well for him.
How well do you think it would've worked out for him if his Rooney Link had popped or his Guardian Angel had fixed whatever was going on back there by giving him the rope at that point?
Better solution (IMHO) would have been to just use the ding dang launch platform.
(Odd comment from someone using the tag of "Foot Launch").

Yeah. It would have. So what's your point? This scenario couldn't possibly have happened in dolly launched aero so we really don't need to be worrying about or discussing Rooney Links?
Carry on with the squabbling...
Yeah. And thanks for your most valuable contribution here. It's through efforts, contributions, and taking of stands like yours that this sport is able to move continually forward.

Zack C - 2013/03/04 14:19:37 UTC

A 200 lb weak link is equivalent to two loops of 130.
No it is not.
It's a 260lb weak link.
How can it POSSIBLY be Jim? Here's what was being taught at the scene of the crime about a single loop:
Quest Air - Aerotow FAQ

Most flight parks use 130 lb. braided Dacron line, so that one loop (which is the equivalent to two strands) is about 260 lb. strong - about the average wing load of a single pilot on a typical glider. For tandems, either two loops (four strands) of the same line or one loop of a stronger line is usually used to compensate for nearly twice the wing loading. When attaching the weak link to the bridle, position the knot so that it's hidden from the main tension in the link and excluded altogether from the equation.
Quest is where Chad Elchin got checked out and qualified and I was told at Ridgely that a single was 260 and a double was 520. And so were you. And the ONLY REASON that they didn't up the weak links on their first weekend of operation (Memorial Day, 1999) when they could only get about one in three gliders off the ground was - as Chad told me when I asked him about it - was that 520 pounds was already stressing the glider a lot more than was prudent and a lot more than Donnell's Sacred One G rule of thumb. And they were still spewing that bullshit in around 2007/2008. So don't you DARE tell me that there was EVER any kind of actual thought process going on behind this 130 pound Greenspot crap of yours.
Either case is stronger than the tug's weak link.
Again, no.
I'm towing 200lb pilots with 3strand 200lb link.
So where's your data on that? Nineteen months ago neither you nor any of your shitheaded buddies at Quest...

What is the line tension required to break the weak link at the tug ?
What is the line tension required to break the weak link on the primary bridle ? (Tandem)
What is the line tension required to break the weak link on the secondary bridle ? (Tandem)
...could come up with anything resembling an answer to Ridgerodent's questions about any of these Industry Standard aerotow weak links.

And last year Dr. Trisa Tilletti published an article in the June issue of Hang Gliding that a three strand was...
What about a three-line weak link?
It is an acceptable method [ref 4], but not necessarily a de facto standard. It can be used to make, for example, a 390 lb. weak link from 130 lb. line for use on a tug.
...390 pounds, since knots have no effect on breaking strength of three stranders - it's just even numbers in which that's an issue. Shouldn't all you keen intellectuals get together and agree what flavors of bullshit you're gonna be feeding the public?

But let's say that it IS 200...

- That means that you're towing a 300 pound glider at one and a third Gs max - before allowing for any increase due to apex angle and the regulation to stay over the glider's weak link.

- And it means that you're towing a 518 pound North Wing T2 tandem at a max of 0.77 Gs - and guess what, motherfucker.
Did you change your mind? If so, why?
The accepted standards and practices changed.
Oh.

- Who the fuck accepted them? I somehow missed that in the USHGA SOPs and FAA FARs.

- On what basis did these stupid pigfuckers who were popping gliders off in mild morning conditions six times in a row and crashing people left and right on fuzzy half G pieces of shit suddenly up things 54 percent?
I still won't tow people with doubled up weaklinks.

Weak link question
Jim Rooney - 2008/11/20 22:25:38 UTC

Something to bear in mind... the tug's weaklink is three strand.

For clarity... A normal single loop weaklink would be considered two. A tandem double loop is considered four.

In the tandem setup, the "weaklink" in the system is at the tug end, not the glider.

Ya'll seem to be missing this.
Once you go beyond three strand... you're not using a weaklink. If the weaklink goes, you're getting the rope.
...ALL tandem flights - even if it's Mitch going up with...

http://www.youtube.com/watch?v=3h1uyn_zTlo


...some five year old kid at what could easily be around the 268 pound minimum flying weight of a North Wing tandem and fifty pounds under my own solo flying weight - use a double loop of the Sacred Fishing Line.

So it's not safe and reliable enough for solo comp pilots like Davis...

You see, I'm on the other end of that rope.
I want neither a dead pilot on my hands or one trying to kill me.
And yes. It is my call. PERIOD.
On tow, I am the PIC.

Now, that cuts hard against every fiber of every HG pilot on the planet and I get that.
Absolutely no HG pilot likes hearing it. Not me, not no one. BUT... sorry, that's the way it is.

...flying weight and...
Zack C - 2013/02/22 03:29:04 UTC

How light is 'very light'? How is this relevant?
...the different rules under which some people get to play?
Morningside decided that they were happy with 200lb weaklink.
Oh, I see. This is all about HAPPINESS!!! Nothing like in sailplaning where you use a weak link to...
Tost Flugzeuggerätebau

Weak links protect your aircraft against overloading.
...protect your aircraft against overloading. I guess that's why they selected the 200 - it's orange and orange is a pretty color that makes people happy! :)
They changed their tug's link...
So they don't tow tandems? 'Cause nobody's said anything about them upping tandem weak links - just solos. And it would be pretty pointless to up the tandem weak link to anything over a double loop of 130 pound Greenspot because:
USAFlytec - 2001/07/14

Steve Kroop - Russell Brown - Bob Lane - Jim Prahl - Campbell Bowen

The tail section of the Dragonfly is designed so that it can accept in-line as well as lateral loads. Furthermore the mast extension, which is part of the tow system, is designed to break away in the event of excessive in-line or lateral loads. The force required to cause a breakaway is roughly equivalent to the force required to break the double weaklink used on the tail bridle. More simply put, the mast would break away long before any structural damage to the aircraft would occur.
Jim Rooney - 2008/11/24 18:54:27 UTC

I'm confused. I never said the tug's ass was endangered. That's why we use 3strand at the tug's end. Using 4 strand can rip things off (it's happened).
(Total fuckin' morons.)
...and they don't just pass the stuff out either.
We get it Jim. If I want to tow at 1.0 Gs - half of what the FAA says I can, and what USHGA said I could for twenty-five years until half an hour after Zack hit the runway - I've gotta suck somebody's dick.

SURELY they had to get YOUR approval, signoff, endorsement, blessing to go through with something as radical as this abrupt and unprecedented *54* PERCENT increase! And after twenty years and quite literally HUNDREDS of THOUSANDS of tows pinging in and fine tuning to 130 to arrive at THE PERFECT one-size-fits-all standard aerotow weak link!

Here you should realize that the whole idea behind the skyting technique is to take flight control out of the hands of the ground crew and place it in the hands of the pilot.
...for your Infallible Weak Link and for setting us on the path that's inevitably brought us to the level of unbridled insanity that we have today.
Seriously. It was announced before the comp that this would be the policy. Some guys went and made their case to the safety committee and were shut down. So yeah, sorry... suck it up.
Ya know, motherfucker... Some day you're gonna tell some hang glider pilot to suck it up once to often - and, hopefully, you may have already done that but just don't know it yet.
I'm not aware of anyone that would make such a blanket statement.
You are now.
Talk to a few more tug pilots btw.

There are times where it's better to be on tow than off tow. Ask anyone that's dragged a dolly into the air.
- I don't talk to assholes like Chris McKee who drag dollies into the air because they're too fucking stupid to see an unstowed pod lanyard as a potential problem.

- What the fuck does that hafta do with weak links? The weak link is supposed to abort the tow whenever it senses that something might not be right?

- Yeah. Let's ask somebody who's dragged a cart into the air...
Bill Bryden - 1999/06

Rob had started to launch once but a premature towline release terminated this effort after only a few meters into the launch roll-out. It is suspected the cart was rolled backwards a bit and the towline was reattached to begin the launch process again. During the tug's roll-out for the second launch attempt, the tug pilot observed the glider clear the runway dust and then begin a left bank with no immediate correction. At that point he noticed that the launch cart was hanging below the glider and immediately released his end of the 240 ft. towline. The tug never left the ground and tug pilot watched the glider continue a hard bank to the left achieving an altitude of approximately 25 feet. Impact was on the left wing and then the nose of the glider. Rob was killed immediately from severe neck and head trauma. Rob's body likely cushioned much of the student's impact. She was basically uninjured but suffered short term memory loss (not uncommon in hard crashes) and did not recall the events of the accident.
Bummer that he was killed immediately from from severe neck and head trauma and was never able to thank Corey Burk for making a good decision in the interest of his safety.

- And it sure is a good thing he didn't have some irresponsible callous heartless asshole like this guy...

Hey Rooney, you're the one that doesn't have a clue who Blindrodie really is. Jim Gaar, never was a tug pilot. He never was a "test pilot." He wasn't around in the "early days" of aero tow. Jim Gaar, is a big fat liar that's all hat and no cattle
although I have heard his wife does have a horse.

Jim Gaar, was a Hang 2 that ran a one horse "flight park" into the ground. He was a Hang 2, somewhat self appointed "General Manager" that then appointed himself Safety Czar of the "flight park."

I think Blindrodie might be a low time Hang 3 by now and the "flight park" went belly up quite a while ago.
Jim Gaar, misrepresents himself as an old timer of substance in hang gliding. It's kinda sad to watch. Pathetic.

I'm not really interested in discussing what an 'argument' is or isn't.
It's obviously when some pompus asswipe fails to recognize the insurmountable brilliance of Jim Keen-Intellect Rooney and question a statement made based on a track record of quite literally HUNDREDS of THOUSANDS of tows.
However, Zack and Deltaman seem pretty consistent with their message.
Well yeah. But look at the lengths of their track records.
Blindrodie is easy enough to discount as a fool.
But let's keep him talking anyway so it will become obvious to the slower kids as well.
I won't bother going back to comment on other folks (purportedly in the weak weaklink camp) who have posted moronic things just because they disagree.
That's OK. I've got damn near all of it covered over here.
Disagreements aside, I appreciate your taking the time to respond.
Not nearly as much as I do.
I hope you continue to.
No worries there. He'll never be smart enough to know when to shut the fuck up after one of these - like Trisa's doing.
To me it makes most sense to use as strong a weak link as possible.
Half a G under what's legally possible ain't a bad idea.
Expecting the weaklink to work as a lockout prevention device seems foolhardy.
Yeah, but when you're forcing everybody up on cheap Industry Standard junk for releases that everyone and his dog has known for decades will be one hundred percent useless you need to leave the pilot with something to pin his hopes on - regardless of how absurdly remote is the possibility of a positive outcome and how high the probability that trying to gear the fishing line for a job for which it's astronomically unsuitable is to result in a crash should all the criteria necessary for a more positive outcome not be met.
Sorry if that word offends anyone, it's not my intent to suggest your a fool for not agreeing.
Assholes like these need to be offended and degraded as much as possible.
I have never tried towing from the shoulders, but it seems to me that if I have an attachment to the keel as well as the glider I would be safer.
Do ya think? If it were the case Davis is so insanely attempting to make we'd start people off one point and graduate them to two after a couple of years.
Prior to getting back into towing, I think I need to learn a lot more.
Zack C - 2010/12/13 04:58:15 UTC

I had a very different mindset too back then and trusted the people that made my equipment. Since then I've realized (largely due to this discussion) that while I can certainly consider the advice of others, I can't trust anyone in this sport but myself (and maybe the people at Wills Wing).
Davis Straub - 2013/03/04 23:55:21 UTC

Great towing today...
Super Davis, glad you enjoyed it. For myself however...

I prefer to fly on days when the towing totally sucks - 'cause the better the towing the lower the probability that there will be anything to sustain the flight when the tow's over.

But, of course, that means to do things safely and sanely you need to have top notch equipment - but if you're happy doing what you're doing with the crap you're using then I am too.
...pro towing at Quest Air.
Great! Carrying on the tradition in Zack Marzec's honor. Of course you could honor him even more by combining being pro toad with a Davis Link but there's still hope that you could blow a 200 in the same scenario and achieve the same results.
A bunch of us here.
Say hi to all the pigfuckers for me next time you see them. And tell them I think it's really great the way they've all put this Zack Marzec bit of unpleasantness behind them and gotten on with life.
Pro tow is my preference.
Great!
You can have your own.
My preference IS that you continue to be pro toad. And with your own world renowned Mini Barrel Release and the safer weak link material that we've all been applauding Bobby Fucking-Genius Bailey for twenty years for discovering and mandating.

No it is not.
It's a 260lb weak link.
By 'it' do you mean two loops of 130? I know several people that have experimentally verified the breaking strength of that configuration to be about 200 lbs. Davis linked to some results just recently:
Davis Straub - 2005/03/01

Steve Kroop, Rhett Radford and I went out again and tested four strands of this line. Steve was able to lift his 185 lbs off the ground, and when I added a very small bit of tugging (slowly) on the line, it broke. Say 200 pounds.
http://ozreport.com/9.049#1
Weaklinks

The others I referred to used load testers for more precise results.
Again, no.
I'm towing 200lb pilots with 3strand 200lb link.
Are you saying you change the weak link on the tug depending on the weak link the pilot is using? Are not three strands of 200 lb stronger than the built-in tow mast weak link on a Dragonfly?

Flytec Dragonfly

You've implied this yourself (in this quote, '3strand' refers to 130).
Jim Rooney - 2008/11/24 18:54:27 UTC

That's why we use 3strand at the tug's end. Using 4 strand can rip things off (it's happened).

Weak link question

Three strands of 200 is stronger than four strands of 130.
The accepted standards and practices changed.
Arguing for whatever the current standards are just because they're the standards is what's made it so hard...
Damn near impossible.
...to make any progress.
But the plus side is that every once in a while an Industry Standard asshole makes a good case for sanity by taking himself out of - and greatly benefitting - the gene pool.
Perhaps those that have been pushing for stronger weak links all these years were right?

I'm glad to see some progress now (Lookout is also using 200 lb line)...
Are you quite sure that making them HEAVIER should be viewed as progress? In the opinion of 48 percent of all aerotow pilots 130 is perfect so there's about a fifty/fifty chance that their opinions of lighter Greenspot would improve if we started putting it in the air.
...but as long as (for example) places are mandating 130, we still have a ways to go.
Anybody considered a federal law enforcement option?
You are now.
No, I said it depends on the circumstances. I have repeatedly said that in a bad situation it's usually better to be off tow.

In lieu of some people that have been listening to the rantings of, I kid you not, a convicted pedophile.
It didn't work two summers ago when Davis and you and tried to play that card 'cause you had nothing else, I made sure it blew up in Bob's nasty pathetic face when he tried to pull the same sleazy stunt, and it's not gonna work for you now. You fucking morons effectively murdered Zack Marzec at the beginning of last month and there's a paper trail over thirty years long documenting it. So knock yourself out - MATE.

And note that even though I've been blacklisted and banned from every operation and discussion group over which you cowardly pigfuckers have some control - I'm still here.

And my name pops up all over the place after all flavors of towing disasters. Here are a few names that don't:

Donnell Hewett - Dennis Pagen - Bill Bryden - Bill Moyes - Bobby Bailey - Malcolm Jones - Russell Brown - Steve Kroop - Paul Tjaden -

Mike Meier - Peter Birren - Steve Kroop - Trisa Tilletti - Davis Straub - Jack Axaopoulos - Bob Kuczewski - Cragin Shelton - Joe Gregor -
Brian Vant-Hull

unless, of course, they've been involved in / responsible for the towing disasters.

I'm getting listened to more and the Kinsley Sykesses aren't kissing your ass quite as passionately as they were the last time you tried to play the "convicted pedophile" card. Assholes like Paul Hurless break out in rashes at the mere mention of my name. I'm the primary source of all the heat you smug little shits are catching right now.

So keep playing your convicted pedophile card. All it accomplishes is to raise my profile and boost my relevance and the Kite Strings hit counters. You're dealing with someone who's got nothing to lose and that can be an extremely dangerous enemy.

I'm NOT a tug pilot but all the tug pilots that worked with me (3) were on board with the current procedures described in this thread.
...he's a tug pilot.

- Flying a three axis controlled aircraft with a powerful and reliable engine, built in takeoff/landing gear, and a solid built in release system at the front of a towline takes a tiny fraction of the brains, balls, skill, muscle, concentration, and reflexes and half the number of hands it does to fly a weight shift controlled, roll unstable unpowered aircraft at the back end of the towline.

Throw in thermals, incompetent douchebag tug drivers (meaning pretty much all of them), Rooney Links on both ends of the towline, other mandated Industry Standard equipment at the back, and the back end guy is simply ROLLING DICE EVERY TIME HE LAUNCHES.

Tugs NEVER get fucked up by gliders. The ONLY thing that fucks up a tug...

Image

...is an engine failure. And that's something that the tug driver - through proper maintenance, procedures, and preflight checks - has a lot of say in avoiding.

The PRIMARY thing that fucks up a glider...

...is an instantaneous loss of the engine power the glider has paid some asshole in a Dragonfly to deliver to him.

And the primary cause of that happening is one of the Rooney Links the asshole in the Dragonfly is mandating to keep the glider safe from the glider pilot's piloting.

...fixing whatever's going on back there by...
Bill Bryden - 1999/06

During the tug's roll-out for the second launch attempt, the tug pilot observed the glider clear the runway dust and then begin a left bank with no immediate correction. At that point he noticed that the launch cart was hanging below the glider and immediately released his end of the 240 ft. towline. The tug never left the ground and tug pilot watched the glider continue a hard bank to the left achieving an altitude of approximately 25 feet. Impact was on the left wing and then the nose of the glider. Rob was killed immediately from severe neck and head trauma.
...giving him the rope.

No tug has EVER been crashed because of:
- a Rooney Link - at either end - increasing the safety of the towing operation
- the glider making a good decision in the interest of his safety and fixing what was going on up there by giving him the rope
- a glider forced up with Industry Standard crap velcroed to its downtube locking out and slamming in

Plenty of gliders have gone down - never to fly again - for all those reasons though.

P.S. Very interesting the way you backed Jim Gaar for whatever OPINIONS he might spew based - not upon any competence, expertise, professionalism, logic, insight he may have exhibited - but rather upon the fact that you THOUGHT he was a pinnacle of human evolution tug pilot, when, in fact, he's nothing but a miserable lying useless Hang Three pudwhacker.

And if he had told you they used three hundred pound fishing line at Adventure AirSports for five years with no issues that would've become an acceptable standard.

We could get into details of lab testing weak links and bridles, but this article is already getting long. That would be a good topic for an article in the future. Besides, with our backgrounds in formal research, you and I both know that lab tests may produce results with good internal validity, but are often weak in regard to external validity--meaning lab conditions cannot completely include all the factors and variability that exists in the big, real world.

When Jim got me locked out to the right, I couldn't keep the pitch of the glider with one hand for more than a second (the pressure was a zillion pounds, more or less), but the F'ing release slid around when I tried to hit it. The barrel release wouldn't work because we had too much pressure on it.

Anyhow, the tandem can indeed perform big wingovers, as I demonstrated when I finally got separated from the tug.

So SURELY you must have some nagging suspicion that the same weak link may perform differently on gliders of varying weights.

And it turns out that Zack actually wasn't all that light - 55 pounds over some of the little girl gliders I've seen using Rooney Links.
