Thought I already answered that one... instead of quoting myself (have a look back if you don't believe me), I'll just reiterate it.
I don't advocate anything.
I use what we use at the flight parks. It's time tested and proven... and works a hell of a lot better than all the other bullshit I've seen out there.

Poll on weaklinks
Jim Rooney - 2013/03/04 19:31:36 UTC
We all play by the same rules, or we don't play.
Morningside decided that they were happy with 200lb weaklink. They changed their tug's link and they don't just pass the stuff out either. If you'd like to know more about it... go ask them.
...now Morningside has decided they're happy with a weak link 54 percent heavier than what "we" use. So...
- What characteristics of the two hundred pound weak link do you think it was that brought Morningside the increased level of happiness they now enjoy?
- Why do you think it is that other aerotow operations don't share in the happiness that Morningside has decided upon?
- Why would anybody be happy with some bullshit out there that only works 46 percent as well as what we use?
- Do you think that...

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 million convenience loving comp pilots with no concern for the safety of the tug pilots got to them somehow?
- I'm assuming Morningside was previously included in "we". What's its status now?
To what did they change their tug's weak link? Back up to the double loop they assumed blew at 1040 pounds towline and was a good rule of thumb for a tandem before they found that a tow mast breakaway designed to break away at the same tension as the double loop would break away at the same tension as the double loop?
Why do we need to go ask them? I was under the impression that...

What can be learned from this "scooter" towing accident?
Mitch Shipley - 2011/01/31 15:22:59 UTC
Enjoy your posts, as always, and find your comments solid, based on hundreds of hours / tows of experience and backed up by a keen intellect/knowledge of the issues when it comes to most things in general and hang gliding AT/Towing in particular. Wanted to go on record in case anyone reading wanted to know one persons comments they should give weight to.
...you were the go-to guy on aerotowing issues. What could they possibly understand that you don't? Or is this purely a subjective happiness Ginger / Mary Ann thing that really can't be defined?
If it's just a Ginger / Mary Ann thing how come the individual pilot can't decide what he's happy with?
130lb greenspot (greenspun?) cortland fishing line.
Which is it? I would've thunk that the go-to guy on aerotowing issues would be a lot more certain about the name of the material constituting the focal point of his safe towing system.
In stock at Quest, Highland, Eastern Shore, Kitty Hawk Kites, Florida Ridge, and I'm pretty sure Wallaby, Lookout and Morningside.
You think Morningside's still got it? They decided they were happy with the two hundred. And there are so many other operations totally enthralled with 130 because it's a proven system that works and has an extremely long track record. Seems to me like there'd have been a major redistribution of resources.
Not sure what Tracy up at Cloud Nine uses, but I'll put bets on the same.
I wouldn't be too hasty on that. Right after Zack Marzec's 130 increased the safety of the towing operation Trisa up at Cloud 9 deleted all references to weak link strength from the USHGA SOPs.
Did I miss any?

Weaklink testing
Mark Knight - 2013/07/04 13:47:57 UTC
My calculations and test suggest the 200 lb. is right for me. I weigh 185 pounds, fly a T2 154 (75 lbs), and my harness fully loaded is 35 pounds. Total all up flying weight is 185 + 75+ 35 = 295 lbs. Times 1.4 = 413. I use Pro tow barrel release so divide by 2 = 206.5. I feel the White and purple is a good fit for me.

I left Quest with some of the towmeup.com material when I was there in April and they were going to do testing as well. I'm not sure what they are now using.
...seems to have gotten a bit tight lipped about what they're using.
Is it clear what I mean by "We"?
No, not in the least. The picture has been getting pretty fuzzy this past year or two.

Sorry, I'm sick and tired of all these soap box bullshit assheads that feel the need to spout their shit at funerals. I just buried my friend and you're seizing the moment to preach your bullshit? GO FUCK YOURSELF!!!!!!!!
I can barely stand these pompus asswipes on a normal day.
...thinking of you as the least bit arrogant.

So you have some precious little ideas that you think COULD magically revolutioniSe (with your pretentious little spelling of the word) The Industry. So you think that The Industry has some serious shortcomings - which, when The Industry is aviation - translate to needless crashes, injuries, deaths. But you haven't shared a whisper of what these precious little ideas are with the hang gliding public because you're much too humble. And you really despise...
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.
Much like confirmation bias, he's come here to shoehorn his pet little project into a discussion. Please take your snake oil and go elsewhere.
Tune him up?
Yeah, sorry... no.
...anyone who isn't as humble as you are and puts his precious little ideas for improving things up in the air and out for public scrutiny.
There are far smarter people than me working this out.
Working WHAT out? Are you telling us that after about a quarter century from the time the Dragonfly first got off the ground there's anything significant about aerotowing that hasn't been thoroughly worked out and perfected? What are our vulnerabilities? Shouldn't we muppets be informed of these totally unknown/unpredictable issues in the course of our training?
I know, I've worked with them.
Well if you're not all that smart - and, trust me, you're one of the most incredibly stupid pieces of shit I've ever gotten to know in this sport - how are you able to differentiate smart people from your fellow snake oil salesmen?

Weaklinks
Davis Straub - 1999/06/06
During the US Nationals I wrote a bit about weaklinks and the gag weaklinks that someone tied at Quest Air. A few days after I wrote about them, Bobby Bailey, designer and builder of the Bailey-Moyes Dragon Fly tug, approached me visibly upset about what I and James Freeman had written about weaklinks. He was especially upset that I had written that I had doubled my weaklink after three weaklinks in a row had broken on me.
...is totally incapable of understanding that a heavy glider weak link is totally incapable of overriding the strength of the tug's weak link and doesn't present more danger to the tug if the number of people under the glider is one instead of two. And those are concepts that you were able to grasp...
Jim Rooney - 2007/07/22 22:30:28 UTC
No, I'm not being nice. No, I do not feel the need to be nice. You're trying to convince people to be less safe. I don't want to be on the other end of the rope when someone listening to this drivel smashes in.
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.

Would someone - Brian, Janni, Lauren, ANYONE - PLEASE PLEASE PLEASE explain to me how the tug's ass is endangered by a double loop ONLY when it's on a SOLO glider but not at all when it's on a TANDEM?
Jim Rooney - 2011/08/31 09:25:57 UTC
See, you don't get to hook up to my plane with whatever you please. Not only am I on the other end of that rope... and you have zero say in my safety margins... I have no desire what so ever to have a pilot smashing himself into the earth on my watch. So yeah, if you show up with some non-standard gear, I won't be towing you. Love it or leave it. I don't care.
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.
...eventually. That makes you one of the smartest Dragonfly drivers I know.

In the old threads there was a lot of info from a guy named Tad. Tad had a very strong opinion on weak link strength and it was a lot higher than most folks care for. I'd focus carefully on what folks who tow a lot have to say. Or Jim Rooney who is an excellent tug pilot. I tow with the "park provided" weak links. I think they are 130 pound Greenspot.

Jim Rooney - 2008/11/24 05:18:15 UTC
Well, I'm assuming there was some guff about the tug pilot's right of refusal?
Gee, didn't think we'd have to delve into "pilot in command"... I figured that one's pretty well understood in a flying community.
It's quite simple.
The tug is a certified aircraft... the glider is an unpowered ultralight vehicle. The tug pilot is the pilot in command. You are a passenger. You have the same rights and responsibilities as a skydiver.
It's a bitter pill I'm sure, but there you have it.
Jim Rooney - 2013/02/16 05:05:41 UTC
Ok, keyboard in hand.
I've got a bit of time, but I'm not going to write a dissertation... so either choose to try to understand what I'm saying, or (as is most often the case) don't.
I don't care.
Here's a little bit of bitter reality that ya'll get to understand straight off. I won't be sugar coating it, sorry.
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.
Accept it and move on.
Not only can you not change it, it's the law... in the very literal sense.
You've invented some total fiction about the goddam stupid gas driver being the Pilot In Command of the aircraft he's paid to haul up and all the useless twats in this sport let you get away with it. And if you can get away with something that outrageous and despicable exactly what twisted little ideas of yours are you afraid you won't be able to implement?

Editorial
A NOTE ON TOWING
The early days of hang gliding were marred by numerous towing accidents. During this period this aspect of our sport established a hopelessly bad reputation. And, indeed, last year, as you may have noted in Doug Hildreth's recent accident review, there was a towing fatality by a totally inexperienced Texas pilot.
Some time ago I received a series of four articles on a new towing system from Texas experimenter and inventor Donnell Hewitt. I ran the first in the series of four articles. Editors learn from experience and if I could roll back the calendar I would run all four at once in condensed form. In fact, what happened was that the first article - which made seemingly outrageous claims without outlining the actual technique or hardware - inflamed the then towing establishment. It seems that today's innovators become tomorrow's conservatives so I was bombarded with calls, some from the USHGA Board, telling me that this Mr. Hewitt was totally inexperienced, that he didn't know what he was talking about, and that I was contributing to the possible injury and death of unknown multitudes of innocent hang glider pilots.
I am not a tow pilot, and although Donnell's system made sense to me I was forced to discontinue the series. The essence of his system was a double bridle that connected to the glider and to the pilot. This system would thus pull the pilot back on line in the event that the glider was inadvertently turned off course from behind the vehicle. This would produce a self-correcting system avoiding the infamous "lockout" the factor which seemed to make towing so dangerous.
Well, it appears that Mr. Hewitt's system not only works but, as I've been told by pilots who have made literally thousands of land tows with it, it works beyond all the most optimistic expectations. One pilot told me, "It is virtually impossible to lock out even if one tries."
The possibilities are obviously incredible if a safe, standardized towing technique can be established. The sport of hang gliding at this point is essentially limited by the availability of flying sites. With land tow the entire country is opened up, and as we have seen by Willi Muller and Bruce Case's world class cross country flights over flat land, the potential is unlimited. In fact, there are certain safety advantages to flying over flat land. The turbulence created by jagged terrain is avoided and the dreaded downwind turn into the hill is eliminated.
In upcoming issues we will try to supply as much information as possible on this new aspect of the sport. Those with experience are invited to contact us about possible articles.
However, any new technique or equipment always produces unforseen problems. Towing must be approached with the most thoughtful and conservative attitude. As Garry Whitman pointed out to me recently, the only problem he has had has been with experienced pilots who won't listen to his instructions. And please remember, the equipment and methods described in this publication are based on the experience of the authors only and are not endorsed or recommended by the USHGA or Hang Gliding magazine.
With the kind permission of Donnell Hewitt we will publish the remaining three installments of his Skyting series in upcoming issues.
...Donnell Hewett - who had no clue as to what he was talking about - came up with a bunch of totally insane ideas...
- "center of mass" bridle which would pull the pilot back on line in the event that the glider was inadvertently turned off course and made it virtually impossible to lock out - even if one tried
- infallible one G weak link to prevent the lockouts the center of mass bridle missed and keep the glider from climbing hard into near stall situations
- reliable release within easy reach
...and with them revolutionized the industry and precipitated the injuries and deaths of known multitudes of idiot hang glider "pilots". And he was able to do pretty much all of that using a typewriter, paper, Xerox copier, envelopes, stamps to tell people stuff they wanted to hear. So I don't know what's holding you back from getting more of your precious little ideas circulated enough to revolutionize The Industry.
Hell, look what you were able to accomplish with landings:

His one-technique-fits-all attitude espoused on the Oz Report Forum has become tiresome to read. It does not work in the fucked-up world of XC landings and weary pilots.
Christopher LeFay - 2012/03/15 05:57:43 UTC
January's canonization of Rooney as the Patron Saint of Landing was maddening. He offered just what people wanted to hear: there is an ultimate, definitive answer to your landing problems, presented with absolute authority. Judgment problems? His answer is to remove judgment from the process - doggedly stripping out critical differences in gliders, loading, pilot, and conditions. This was just what people wanted - to be told a simple answer. In thanks, they deified him, carving his every utterance in Wiki-stone.
So c'mon, Jimmy. Tell us what some of your precious little ideas are.

- Why did they tell you they have no interest in you helping them work this out?
- If they're far smarter than you and have told you they have no interest in you helping them work this out why do you continue to cling to your precious little ideas?
- Are these people so much smarter than you that you're incapable of understanding why your precious little ideas suck?
- If you're not smart enough to understand why your precious little ideas suck then how good an idea is it for you to be inventing and dictating policy to us weekend warrior muppets while violating the crap out of FAA aerotowing regulations every time you go up with a glider behind you and condemning the statements and work of T** at K*** S******?
