Damn. You posted again a short time before my response was gonna be off. Bear that in mind while reading the following sequence.

I'm in San Diego this week so my goal is to spend more time flying and less time typing for now.

No problem, I've always been in favor of people getting into the air whenever it's going up.

Without reviewing the topic, I think we've learned we need people at the helm who are better than "the stupidest person ever to put a hand on a tiller".

No, we most assuredly did not.

1. We already knew that six thousand years ago.

2. The ship was not driven onto the rocks because the crew members were stupid.

3. Each and every one of us is the the stupidest person ever to put a hand on a tiller on occasion.

We had regulations in place to guard against and compensate for predictable and universal human stupidity and they were neither enforced nor followed.

Most of us fly with and are sometimes required to fly with helmets and parachutes primarily to guard against and compensate for predictable human stupidity - and it's hard to argue that both shouldn't be mandatory for aerobatics competitions.

My short answer is that I think we (society) should provide lots of information about what we feel is safe and what we feel isn't.

For the purposes of this exercise "we (society)" is a very small and odd branch of aviation and there's absolutely no goddam "feel" about it. This is about what everyone with half a brain or better - somewhere around one or two percent of the participants - bloody well KNOWS in no uncertain terms is safe or certifiably insane.

Verifying that you're hooked in immediately prior to stepping off a two hundred foot cliff is safe. Assuming you're hooked in based upon what you think you remember doing thirty seconds ago is certifiably insane. But what do we teach?

Cragin Shelton - 2005/10/03

I remarked that 'you are not hooked in until after the hang check.'

flyin_canuck - 2011/03/01

Nothing creates carnage like declaring a spot landing contest.

But what does USHGA train and FORCE people to do to get ratings?

We KNOW that every time you take a hand off the basetube within striking distance of the ground your chances of killing yourself go up by a factor of ten thousand, or, on tow, fifty thousand - but what does USHGA FORCE people to do during landing approaches and where does Wallaby put its release actuators?

Ann Fawkes - 2011/03/02
Western Europe

If the conditions are such that you need to choose between a controlled wheel landing or a risky foot landing, go for the wheels and try the foot landing in better conditions. Landing unharmed is your first priority.

Not in USHGA's book. It doesn't matter so much if you get killed on a landing. What matters is that you prioritized getting down on your feet all the way to the bloody end. I can name you two people killed by that mind-set in the past sixteen months.

But I don't think society should be picking up the tabs for nearly as much as we do. We've become a "nanny state" and we haven't figured out yet that we (as a society) can not now (nor never could) afford to provide the best possible care for everyone who does something stupid.

So what do we do? Do we leave Bill Floyd in a crumpled heap for the gulls and crabs to start working on while he's still got a faint pulse 'cause we've made a spot call that his was an unacceptable level of stupidity?

What about the uninsured kid I'm inventing that he landed on? Shouldn't have been there 'cause he shoulda known that hand gliders are more worried about having their parachutes repacked every six months than they are about flying with them and they never check their sidewires?

Who said anything about the best possible care? I'm talking about keeping him alive, not chocolate mints on his pillow every morning. And sometimes the best possible care is the only kind worth doing - all or nothing.

Wouldn't it be a lot less expensive, cruel, and morally vexing if Bill's nanny state agent handed him a hundred dollar ticket and one month suspension of his license for flying without a chute and/or failing to preflight the wing? EVERYBODY would be thrilled with the outcome, relatively speaking, Bill would get back in the air a year sooner, and we'd have an extra quarter million dollars we could use to cure a half dozen kids who got leukemia through no fault of their own.

I have a lot of faith and respect for Joe...

I haven't weighed in either for the same reasons. And I don't have the time to do the background work to make an informed decision. If you put a gun to my head I'd go Joe 'cause I know Joe and I know Davis, but I suspect I'd find some gray if I dug deeply enough in an issue like this.

I like what I'm doing 'cause it doesn't take any brains or deep thinking and I can keep people from getting crippled and killed. A bent pin will lock up, a straight one won't. Black and white, two plus two. Lotsa bang for the buck.

If you can point to someone who takes the other side and bring them here for a debate, that will certainly help me feel more confident that I know what's going on.

WHAT OTHER SIDE? THERE IS NO FREAKING OTHER SIDE. In order for there to be sides you'd hafta find somebody who'd actually read either the existing SOPs or the proposed revisions (preferably both) and that person DOES NOT EXIST. Just finding a hang glider pilot who can partially comprehend a written sentence without three or four roflcats in it is a major challenge.

If you want another side get Jack and Davis over here and give them lockdown and banning privileges.

The problem with this forum now (and an even bigger problem with your new forum) is that there aren't enough people on here to get that kind of discussion.

bulls***. You need TWO people who want to have a discussion for a discussion. At Kite Strings we've got four people engaging in discussions. These are infinitely better discussions than the ones I've engaged in with four thousand members, 99 percent of whom are a**holes. At Kite Strings we're all in agreement with two plus two equals four and we're occupied with discussing how best to use that equation in our designs and procedures instead of arguing with Tracy, Head Trauma, and the rest of the two plus two equals whatever I say 'cause I fly more than you crowd.

I just don't know enough (and maybe don't have enough need to know enough) to do that for you.

As an engineer, I'm interested in everything, but if I follow each detail, then I won't be able to build the bigger organization.

If you wanna head/build a national hang gliding organization without a reasonable understanding of towing then you better move to Switzerland 'cause the overwhelmingly vast proportion of this nation is too flat for anything else. Hang gliding pretty much evolved from water skiers with flat kites - like Bills Bennett and Moyes - to begin with and if you don't understand the dynamics of towing you probably don't understand the dynamics of free flying either. Donnell dug us a real big hole in the early Eighties 'cause he didn't understand the dynamics of free flying and how easily they translated to towing.

And I keep trying to tell you that pretty much everything you really need to know is ten-year-old kid with kite stuff. But you're not engaging me on it or asking any questions so I can't walk you through it. Read a paragraph and if there's something you don't understand or believe to be erroneous I'll happily spend a month with you to reach a resolution - in your favor if absolutely necessary.

I tried to do that right out of the gates with the HGAA and it quickly became a power grab by Jack Axaopoulos.

The framers of the US Constitution wrote it with checks and balances to deal with Jack and Davis. The communists assumed there weren't people like Jack and Davis so they ended up with Stalin in pretty short order.

So I think we'll need to come up with a "constitution" to keep that from happening again before I hand over power of the US Hawks to an unruly mob.

But I'm not expert enough in the specifics of towing or training or tandems to be any help there. That's why I'm trying to bring together the experts to handle those disciplines.

You got one. I can freakin' bury you with credentials and references. Use him. If he turns out to be a whack job like Jack says you can have him killed before you relinquish power to a constitutional government.

But, again, my nephew isn't going into any branch of aviation controlled by a democracy of pilots. I'd be a thousand times more comfortable with him slamming F-18s down on carrier decks than spot landing hang gliders at Ridgely 'cause that culture isn't controlled by a bunch of SH*THEADS with no qualifications beyond being able to afford a couple of Dragonflies and the ability to fly them - it's controlled by a century's worth of evolution controlled by physicists and engineers with degrees and accountability.

So maybe we should start establishing constitutional foundations like "It takes two hands to fly a hang glider." before we decide whether or not Hawaii counts as part of the United States with respect to the issue of presidential birthplaces.

The big question that will determine a lot of our structure is what do we want this organization to be?

Fer starters and before anything else get's rolling... 100.000 percent COMPETENT. We knock a zero off the end we needlessly kill one person in ten thousand. We knock off two we're back down to USHGA.

Will it be a "political party" for hang gliding interests in an increasingly paragliding world?

You deal with them on the ridge, I'll take care of them on the tow strip.

Will it be an advisory body for hang gliding safety?

Hang glider pilots in the air - just like automobile drivers on the road - need something considerably more menacing than "advice". We can and do kill ourselves, our passengers, our students, other planes, and innocent bystanders.

Will it be an independent organization providing ratings...

I fervently hope so. And I hope the requirements are as consistent and brutal as the ones for the certification of the freakin' gliders we're gonna put people on. "Wow! Did you see the dive recovery results on the new Wills Wing U3! Pulled out NINETY PERCENT of the time!" But an eighty on the written for the Hang Two is pretty damn good.

Will it be a bunch of outcast crackpots talking only to themselves?

Probably. But as long as we're learning something and somebody's talking to somebody it's better than nothing and there's a spark of hope.

But "better" has many dimensions, and we may agree on some and disagree on others.

Then let's get the knock down / drop outs underway and reach some resolutions.

What do you want me to do about it?

Engage me. (That's legal in lotsa states now.)

Call it something like "Request for Comments: Proposed US Hawks Towing Policy".

I did that for about three months at Peter Birren's:

"skysailingtowing - THE TOWING LIST for all towed gliders"

except, it goes without saying, for Tad, before the brain damaged little shitt pulled the plug on me. Seven hundred members including some USHGA Towing Committee with towing as the uniting interest - and ya know what I got in the way of substantive comments?

Looking at Hawks people and extrapolating, how much response do you think I'm gonna get here, especially when one of my top prospects is Sam who won't even bother reading, let alone responding to, an eight sentence answer to a question of his 'cause it's too "long winded"?

I posted the link to that documentation here over three weeks ago and so far I've had about the one percent of the zero I got from Peter's cult that I've grown accustomed to.

I spent the better part of four days on the road getting to and from Lookout 'cause Matt invited me down there for a discussion of the issues but that motherfucker couldn't be bothered to spend the twenty minutes it woulda taken to read them either and was only interested in using me and my load tester to find out what his release and weak links would do like I was one of his employees.

Nobody - including/especially the members of the Towing Committee - reads or makes any attempt to comply with the existing regulations, why would anyone expect anyone to give anything else the most cursory glance?

Publish it in an organized manner so people can find their way through it. If you do that, then I promise I'll read it and post my comments.

IT'S BEEN PUBLISHED FOR YEARS.

http://www.energykitesystems.net/Lift/h ... index.html

SOPs and Guidelines. About the equivalent of thirty pages - A LOT of which is empty space and just pulled from the existing USHGA stuff that nobody ever reads.

Finally, I hope you don't mind this comment, but I think it might help you.

Nope, I never mind any constructive or well intentioned comment.

I would guess that 10% of all people are highly offended by foul language.

1. And yet from everything I've ever heard the fiber optics of the internet are just barely able no support the weight of all the porn that flows through them.

2. Foul is a subjective adjective. I don't consider calling Matt a motherfucker to be foul language 'cause my identification of him as such is accurate (Asterisk - If he were a literal motherfucker I'd never call him that - I'd hafta come up with something else.) and will decrease the reader's probability of ending up as a mangled corpse at the base of an escarpment or just off the side of a runway.

This:

The new GT aerotow release, new as of July 11th 2009, is designed to be used with a V bridle and a 13O-pound green stripe Dacron tournament fishing line weak link. At this time it is not recommended to use this release with a higher value weak link.

I consider to be totally OBSCENE language 'cause that's exactly the kind that has gotten people killed and will continue to do so.

And I'd guess that of those 50% (highly + moderately), they all tend to be dismissive of people who use that language.

I'm totally OK with that 'cause I'm always thinking about the gene pool. These are the people who are totally horrified by the four letter words in "Saving Private Ryan" but pretty much totally OK with the concept of people turning flame throwers on each other.

Now if you really and truly want to change things, then you've got to realize that you're only hurting your own credibility with about 50% of the people for something as simple as your choice in words.

Ignoring the fact that there's a lot of people in this sport I wanna see dead... You've invented some numbers and are now drawing conclusions from them as if you were working from actual data. I would suggest that hit counters on my threads all over the glider fora indicate the precise opposite.

Now I can imagine a response that says "people shouldn't be offended", or "people who are offended don't matter".

Yeah, I'm good with either/both of those.

But whether that's true or not, it doesn't help any future Shane's to have anyone "turned off" or "put off" by your language.

Shane had just come back from two years of saving souls in Guatemala (I'm guessing on behalf of a religious cult that functions exactly like USHGA - question the leadership on anything and your a** is gone, for the rest of your life or all eternity, whichever comes last) instead of listening to me so I could save his life. So the next Shane can think a little about what kind of person he's best off paying attention to.

So I'm asking you to think about whether it's more important for you to build the support to actually make a change or if it's more important to spit out a bunch of cuss words that lose a good percentage of your potential audience.

Again, the ASSUMPTION thing. You always need data. Kinda like your ASSUMPTION that evolution inevitably leads to something "better" while all the data is indicating the precise opposite in a lot of relevant scenarios. We tow people were in pretty good shape with the Brooks Bridle in 1981 and now Davis Releases are multiplying like Asian Carp closing in on the Great Lakes.

Hi Tad,

It's late here, and there's way too much for me to reply to right now (I'm still on vacation in San Diego). In fact there may be more here than I'll ever get around to replying to. It's not that I don't want to, but I can see how these discussions could grow exponentially if we interleave each post with our own replies and then further subdivide those replies as well. Maybe that's a better (more modern) example of exponential growth than rodent populations!

I will say that I enjoy your writing. I tried to make mental notes of where to add this guy ( :srofl: ), but in the end there were too many good lines and I was too tired to keep track. There are many places where we differ, and we could run down those topics, but I don't think they'll get us anywhere. So instead I'd like to focus on something concrete. You wrote:

Your legacy will be enduring, Tad. Your energy has been providing synergy that has been affecting the slow evolution of towing safety in hang gliding. The lateral emotional challenges have their play, but the mechanical servants persist; thank you for feeding those servants.

Can you tell me which one(s) of those you'd like to propose for the US Hawks towing standard?

Thanks in advance.

Maybe that's a better (more modern) example of exponential growth than rodent populations!

Careful. If that's a reference to Australian bunnies, rabbits are NOT rodents - infinitely more so than Redtails not being hawks.

I tried to make mental notes of where to add this guy...

I'd be honored if you threw me into the Doug Hildreth shoebox.

Lemme throw R.V. Wills out of the Accident Review Committee Chairmen can of worms. He was excellent but he was reporting on and analyzing the bloodbath of the Seventies which was a whole nother ballpark.

Doug - 1981-1994 - was the only Chairman USHGA's ever had in the history of modern hang gliding to look at the manglings and killings and question our basic approaches to doing things. Everybody else accepted the way we were doing things as being carved in granite and focused on trying to train the pilots how to keep from mangling and killing themselves in the situations and environments we were providing and mandating. I'm so sorry that he died before I got a chance to kiss his boots.

There are many places where we differ, and we could run down those topics, but I don't think they'll get us anywhere.

We eventually gotta get somewhere on damn near everything and it shouldn't be too tough 'cause civil and military aviation has been doing it for a century and we don't hafta reinvent the wheel - the way we've been trying and failing for well over a third of that.

But lemme state where I think we have the most fundamental differences - the ones which may keep our horns locked for some time to come. My position is that freedom and hang gliding (or any other form of aviation) is a really crappy mix.

Whenever I see on high school classroom walls inspirational posters with hang gliders and references to FREEDOM on them I think "bulls***."

If you run off the ramp and the air's not doing anything you've got a few options for how you wanna spend your time going down but you ARE GOING DOWN and you'll have one shot at landing without killing yourself so you probably don't wanna get TOO creative.

If you soar the dunes you're generally operating within some extremely narrow and strict limitations all the time.

If you soar a mountain ridge you've got a lot more breathing room but you're still a prisoner of the ridge. It's got ends. If you get too far out front you're going down. If you get too far back you're going down upside down. And they can get boring as hell. People have been known to try to slash their wrists, but there's not a whole lotta damage you can do with a hook knife.

If you thermal you need to concentrate on what your eyes, inner ear, glider, vario, intuition, and nearby gliders and birds are telling you or you may fall off the edge and may not get another chance to do it right this flight.

If you're going XC your freedom is very likely to be constrained by vast tracts of unbroken forests and circles drawn on sectionals around big airports.

If you're doing aerobatics and get too carried away with the freedom thing you may easily find yourself part of a spinning mess of wires and broken tubing while trying to figure out your best option for getting a parachute clear of all that crap.

This is going to sound cold, but I believe people have a right to make their own choices.

When those choices involve incompetently and/or unreasonably endangering oneself - let alone others - I absolutely do not.

I've been to three hang glider launch funerals - two tow, one ridge. How 'bout you? When someone kills himself on a glider he's not the only one affected.

We can and do kill ourselves, our passengers, our students, other planes, and innocent bystanders.

I missed at least one biggie on that one. I was just gonna post Paragraph 6 but read the whole article.

Hang Gliding - 1986/06

Rob Kells and Mike Meier

A Farewell To A Friend

Dan Racanelli was a pilot's pilot. He began flying hang gliders in the early days, at a time when rigorous airworthiness testing was unheard of, and when the inherent limitations of a given design could only be determined for certain by exceeding them.

Rac was a pioneer of aerobatics in hang gliders at a time when almost no one felt that it was possible to safely perform aerobatics in an aircraft of such marginal strength, stability and control. As a result, among those who knew him mostly by reputation, Rac was often thought of as a crazy pilot.

But he wasn't. What he was, was good. So good that things which would have been radical or crazy for almost anyone else were well within the limitations of his remarkable abilities. In the late seventies, before most gliders had pre-formed battens or enclosed crossbars or top speeds of much more than 40 mph, Rac was doing beautifully executed 180 degree rollovers that were so smooth you could have imagined him balancing a glass of water on top of his helmet.

Rac never made a serious effort to become a top competition pilot, but from time to time he would fly in a meet here and there. He was Northern California Regional Champion one year. In 1981, he won one of the first aerobatic hang gliding meets ever held, in Telluride. In 1982, he won the First Annual Fort Funston Air Race; a competition which measures, perhaps better than any other, both a pilot's ability to control his glider with absolute precision, and his total confidence in that ability.

When rain forced a break in the '81 Telluride meet, a film documenting the event interviewed Rac an camera. The general thrust of the film was to portray aerobatic hang gliding as a daring activity, fraught with unspeakable danger and the constant threat of imminent catastrophe. Asked whether he was exceeding reasonable limitations by performing aerobatics, Rac told the story of an early accident in his career, and aerobatic induced structural failure, and of how the incident had drastically slowed his rate of progression in learning aerobatics. He spoke of his concern for some of the younger pilots who were, he thought, coming along a little too fast, and of his hopes that the newly developed aerobatic competition format would provide a context for the new pilots to learn slowly and safely the skills required for aerobatic flight in hang gliders.

In the end, it was Rac's concern for safety and for his fellow pilots that cost him his life. He was flying in the Australian Nationals with his friend, Rick Rawlings, on final approach to an unfamiliar field, Rick became entangled in power lines that were invisible from the air. Well aware of the immediate danger to both Rick and himself, Rac immediately landed nearby to try to help. The wind was gusting, and as Rac ran towards the suspended glider, he lost his balance and threw up one arm. The glider swung suddenly in the wind and a batten hit Rac in the hand. Approximately 40,000 volts traveled through his body and into the ground. Rick was able to lower himself out of the glider without becoming grounded and for thirty minutes he administered CPR to Rac in a desperate but unsuccessful effort to save his life. In all probability, Rac had been killed instantly at the first contact with the glider.

It's a hard thing to lose a friend, and it's harder still for the pilots to lose one of their own. None of us likes to dwell on the dangerous aspects of what we do, and when someone whose consummate skills we so admire is killed, it makes us all feel a lot less immortal. There are not likely to be many pilots we will like as well, or respect as much for their abilities as Dan Racanelli.

We will miss him.

1990/10/21 I was looking forward to a little airtime at a new Shenandoah Valley site (Fetzer Gap) before, at 14:30, a bozo in my party of three started turning right to hug the ridge before he cleared the slot. So I got to spend the rest of a beautiful fall day WAY high in an oak WAY out on a rather narrow limb getting his useless a** and glider down as intact units with ground support from the kind and generous landowner who did not afterwards close the site. He got nothing, I got a third of the gas money for the trip, scrapes, dehydration, and some really nasty leg cramps.

At Kite Strings, just last night, regarding a fairly innocently and minorly blown landing with catastrophic consequences, Zack posted...

...that incident cost me a lot (in far more ways than just financially) and cost people I care about a lot as well.

This is going to sound cold, but I believe people have a right to make their own choices.

In a John Wayne movie, maybe. In real life hang gliding I'm not buying it. It NEVER works out that way. Being human we have the God given and inalienable right to phuck up every now and then. We do not, however, have the right to CHOOSE to phuck up beforehand.

Mother Nature has very strict rules and when we, as a hang gliding culture, set very strict written rules to help us stay in line with hers and enforce them before she does we end up with more and happier and healthier pilots getting more, better, and cheaper airtime.

Can you tell me which one(s) of those you'd like to propose for the US Hawks towing standard?

C'mon Bob, I know it was late but here's what I wrote in my previous post:

http://www.energykitesystems.net/Lift/hgh/TadEareckson/index.html

SOPs and Guidelines.

There are only two files that resemble that remark. This ain't the Japanese naval code we're trying to crack here.

Those aren't standards and procedures for ALL towing - just aero 'cause that's:

what I was asked to write;
all we have 'cause we do it under the auspices of the FAA and are required to have something;
coolest and most effective;
the flavor with which I'm most familiar.

But there are plenty of elements which are directly applicable and/or easily translatable to surface flavors - including paragliding.

So, for the time being, let's work on those. Or one of those. Or one part of one of those. Or one sentence of one part of one of those.

the sound of crickets...

So.. is everyone hunkered down in their fallout shelters?

Correction: Is everyone hunkered down in their fallout/CO2 shelters?
(CO2 shelters, otherwise known as plant GREENHOUSES in our CO2 starved atmosphere)

Maybe Bob is on a secret Obomba 'humanitarian' mission in the north of Africa?

Could things get any worse?

Hi Warren and Tad,

I'm sorry about the crickets. I just got back from my week in San Diego on the 21st. It takes me a day or two to get readjusted to the time changes and the surroundings changes.

I also happened to notice that the Demo Days at Wallaby Ranch started today. So I drove down there for the first time and met a bunch of my Crestline friends there. I brought Little Hawk and a bunch of us had fun running with it on the LZ. I used my Flip video to tape some of it, and I'll try to extract some stills to post tomorrow.

I may take a tandem towing flight there soon just to get my first taste of hang glider towing. I've towed in sailplanes before, and maybe it won't be as bad as I'm dreading. That may give me some level of practical experience to use in discussing Tad's proposals.

By the way, there's a discussion titled "USHPA and Funston" at the following site:

http://flyfunston.org/bbs/viewtopic.php?f=5&t=1106

I may cross post some of it here when I get a chance. It demonstrates the arrogance of some USHPA Directors toward their members. It's a lesson I hope to never see repeated on the US Hawks!!

Sailplane towing... Excluding motorgliders, kinda redundant. Solo?

If you understand sailplane towing you understand pretty much everything you need to to understand hang glider towing. Hell, as I keep trying to tell you, if you understand kite flying you understand pretty much everything you need to to understand hang glider towing.

Wondering if you've read either the existing USHGA aerotowing SOPs or my revisions? My revisions are pretty much just the same as USHGA's with some common sense thrown in. And if there's ANYTHING in them that requires that you've ever towed, flown, or seen a hang glider I'd sure like to know what it is.

Will a tandem tow at Wallaby be as bad as you're dreading? I'd wager the chances of you getting f***ed up on the drive over are about five times as high as those of you getting f***ed up on the tow. Nevertheless, I wouldn't be eager to take a hop - tandem or solo - at Wallaby or any other US aerotow operation I know anything about 'cause there are absolutely moronic and deadly flaws left in or deliberately built into the systems that most assuredly do not need to be there.

You've got revolver with a million chambers, only one of them loaded. Spin the cylinder, point it at your head, pull the trigger, get a weekend pass to Disneyland. You ask the guy at the booth if you can remove the round before you spin and pull. He tells you no. You ask why. He says 'cause this is the way everybody does it, this is the way it's always been done, we've done it a hundred and twenty thousand times before, we've never had a problem, and who the hell are you to be telling us how to run our booth anyway?

That's the kind of game you're gonna be playing 'cept there are gonna be a dozen bullets - all ones that the sailplane guys were smart enough to remove ninety years ago - and a fraction of the number of chambers in which to distribute them.

What of use do expect to learn from going on a Wallaby pony ride? You've got rubber O-rings on your solid rocket boosters. They become hard and brittle and don't work at below freezing temperatures. It's gone down to eighteen Fahrenheit the night before and the Challenger is one giant popsicle the next morning. How many times do you need to have blasted into orbit to be able make the call? How does having blasted into orbit a hundred times make you the least bit better qualified to make the call than a fifth grader?

How many aerotows do you need to have completed to know that it's a lot better for the glider - not to mention the operation - if the tug keeps the towline when they go their separate ways? I'm thinking you'd have a hard time finding a seven year old kid - who isn't a tug driver - too stupid to grasp this concept. The FAA understands it and thus requires the weak link at the front to be stronger than the one at the back. I understand it. USHGA and the flight parks don't understand it and thus gliders end up with 250 foot ropes draped over their basetubes all the time.

Bart Weghorst - 2011/02/25

Most of the time. But I've had it once where the pin had bent inside the barrel from excessive tow force. My weaklink was still intact. The tug pilot's weaklink broke so I had the rope. I had to use two hands to get the pin out of the barrel.

No stress because I was high.

That's two ways to kill the glider deliberately built into the system before it ever gets off the ground.

How many tows do you need to have completed to know that if you're using a weak link that allows a release to see as much as two hundred pounds you can't use one that welds itself shut at half that?

Lauren Tjaden - 2008/03/23
Quest

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.

That's four ways.

So how many iterations of this bulls*** do we let these a**holes get away with up high before we put their fu**ing tickets in the fu**ing shredders to keep them from mangling or killing the next Holly Korzilius or Bob Kuczewski? How many tows beyond zero do you need to do to understand that a bent pin release won't work under load?

http://www.wallaby.com/aerotow_primer.php

If that crap doesn't scare you shitless you haven't been to enough funerals.

You've got three big aerotow parks in your neck of the woods and they're all feeding off of and reinforcing each other's incompetence.

That flight of Lauren's is the one you COULD have. And hers was under controlled conditions at altitude in smooth air. Yours could be thermal induced and you could start performing those big wingovers - assuming you had time to finally get separated from the tug - at a hundred feet.

So you go take a hop or two at one of these clown colleges. But bring your own Kool-Aid 'cause the instant you start learning anything from any of these people is the instant you're gonna start getting stupid and becoming part of the problem.

Understand that - unlike sailplaning - you're flying a plane that demands both hands on the wheel at all times and becomes dangerously roll unstable on tow. Beyond that, anything you're seeing and/or being told that differs from sailplaning is WRONG. Trust NO ONE.

Responding to the discussion at "Little Hawk at Wallaby Ranch"...

Good luck if you choose to fly there with a bent pin release.

The only choice you're gonna have on a tandem flight is to fly with the bent pins or not fly - they're on the shoulders of whoever is gonna be taking you up.

A clued in tandem passenger with a ready hook knife could be the third hand that your instructor doesn't have when you get that rare 'loaded chamber' lock out.

1. The idea of a clued in tandem passenger is somewhat oxymoronic - if he's clued in he probably doesn't need to be a tandem passenger.

2. Not meaning you, Warren, but tow people who think of hook knives as emergency releases are total a**holes. The analogy is something like tying a rope to your trailer hitch and running it through your window to an anchor on the floor mat so you've got a Plan B for when your shitt braking system fails. It might work but never fast enough in a situation in which you need it to, auto manufacturers build redundancy into the hydraulic system so that you're never gonna need it anyway, and even if that failed you're still gonna better spend your time pulling up on the parking brake.

http://www.hanggliding.org/viewtopic.php?t=16384

3. Yeah, when you've got half as many hands as an octopus available to do stuff underneath a glider there's shitt you can get away with that you can't with just two. I'm positive that once you've got a passenger to the point that he has a concept of up, down, left, right you can take advantage of him to mask a lot of problems that are gonna reemerge when he goes solo. Gives him confidence and a false sense of security - if that's not too redundant.

4. Tandem lockouts are virtually nonexistent.

- The people going up with the passengers and students may be and almost always are total idiots but they ARE highly experienced and skilled.

- The gliders are kinda slow and stable.

- They've often got that half an octopus card up one of their sleeves.

Raising this proposition on the flight line, or elsewhere, could be quite entertaining.

It could also end your towing career before it begins. If I were you I'd keep my mouth shut and just observe what's going on. If it's entertainment you want...

Bill Bryden - 2004/04/01

Some aerotow releases, including a few models from prominent schools, have had problems releasing under high tensions. You must VERIFY through tests that a release will work for the tensions that could possibly be encountered. You better figure at least 300 pounds to be modestly confident.

Maybe 8-10 years ago I got several comments from people saying a popular aerotow release (with a bicycle type brake lever) would fail to release at higher tensions. I called and talked to the producer sharing the people's experiences and concerns. I inquired to what tension their releases were tested but he refused to say, just aggressively stated they never had any problems with their releases, they were fine, goodbye, click. Another person tested one and found it started getting really hard to actuate in the range of only 80-100 pounds as I vaguely recall. I noticed they did modify their design but I don't know if they ever really did any engineering tests on it. You should test the release yourself or have someone you trust do it. There is only one aerotow release manufacturer whose product I'd have reasonable confidence in without verifying it myself, the Wallaby release is not it.

That's the response you're gonna get. (And if Bill weren't the idiot he is he coulda just looked at the Quest modification he's talking about and immediately known it made things a lot worse - by a factor of about 2.6 by my test results.)

I think that Tad's assessment is accurate...

One of the things Wallaby got right - about eight years after publication in Hang Gliding of my letter to the editor - was to put weak links both above AND below the tow ring. If the bridle fails to clear the ring there's virtually always a jolt violent enough to blow the secondary weak link so the bent pin release is very unlikely to come into play anyway.

I've been able to pull a bent pin release directly loaded to 400 pounds. It takes over 64 pounds of effort and there's nothing left of the pin afterwards but it can be done - if you're not real busy with other stuff at the time.

And there's a guy at the other end that can and often does do the job of the guy on the glider.

The surface - which is the only thing that can hurt you - almost always suppresses vertical air movement - which is the thing must likely to put you out of control and point you towards it. Something of a self correcting problem.

So you've got all these redundancies and mitigating factors which almost always allow you to get away with shitt equipment and procedures. You generally hafta have about three things line up just right at a low altitude in order to kill somebody, one of them's ALWAYS gonna be pilot error, and thus you never hafta fix any problems. And thus you're gonna guarantee a very low but predictable and totally unnecessary kill rate.

Mike Haas didn't die because he had a piece of shitt Wallaby release that he couldn't get to and a weak link that blew when it didn't need to at the worst possible time while he was trying to cope with a nasty thermal blast -
he died because he wasn't very proficient at keeping his glider under control on tow.

The goal of the tow operations is to get lotsa paying customers into the air, suppress incident data, protect themselves from any threat of expensive and/or embarrassing equipment recalls, and fully blame the crippled or dead pilot for anything and everything that goes wrong. That will NEVER change in the absence of an independent regulatory agency with big sharp teeth whose goal it is to optimize the safety of every flight by outlawing and grounding shitrigged equipment, procedures, and personnel. And you're heading straight into the Ground Zero of shitrigged equipment, procedures, and personnel.

Don't ask questions - I can answer any you've got in enough detail to make you wish you'd never been born. Look around and ask yourself stuff like whether a spinnaker shackle is an appropriate piece of hardware to be used as a primary release mechanism, whether you'd be able to get to the lever on the right downtube if you fell to the low side in a hard left roll, which weak link - tug or glider - is gonna blow first, what the weak links being used are supposed to accomplish, if the secondary bridle really needs to be two or three feet long...

There should at least be some kind of justification for it even if it is wrong.

The justification is that nineteen and a half years that's what Bobby had lying around within grabbing range, he didn't give a rat's a** about FAA/USHGA towing regulations, he - like the rest of hang gliding - has no freakin' clue what a weak link is, this is the way everybody does it, this is the way it's always been done, we've done it a hundred and twenty thousand times before, we've never had a problem, and who the hell are you to be telling us how to run our booth anyway?

P.S.

axo - 2009/06/20

I always check my spinnaker shackle hook and the cable. Mine is still pretty much new and has worked perfectly.

But I have seen others fail twice and one of them was during one of my training tandems. I just kept hitting the brake lever for a few seconds in WTF mode, and the instructor used the barrel release.

That's UNDOUBTEDLY at Wallaby. That's about six ways to get killed. No freakin' way in hell I'd fly that.

Alfie Norks - 2010/06/03

Speedy recovery to the pilot in question.

It could have been worse. It could have happened at ... the other place (but nothing happens there). 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. She was trying to dial 911. My friend suffered lower back injury.

That's also UNDOUBTEDLY at Wallaby.

So statistically... You're gonna be OK.

But a responsible pilot would never go up on crap like that. I'm not saying don't or that I'd be critical of you for taking a hop or two - given the reality of the situation - but you now know the lay of the land at Ground Zero.

My first aerotow was foot launched behind a fast tug on a glider with a LOT of pitch stability towing off my shoulders only with a three-ring release I had to reach for to blow. But the danger of all that was at least manageable to some extent and pales by comparison to what we've EVOLVED to at the major flight parks in the two dozen years since.

So lotsa luck and get back to me when you can.

Hey Tad,

Thanks for the time to write all those comments.

If you read the Wallaby topic you'll see that I did fine and now I'm dabbling my toes in the world of towing. I've still got a lot to learn, and I appreciate the insights and questions that you've given me. Of course, I always try to do my own independent research, and that's what I'll be doing here. I hope to be doing lots of flying, but if there's some down time then I'd like to do some of the tests that you've suggested ... just for my own curiosity and interest (I'm an engineer by profession and inclination).

As I wrote on the Wallaby topic, I was very happy with the experience. It was a great little flight, and I'd like to thank Malcolm for making it so easy.

Thanks for the time to write all those comments.

No problem, plenty more where those came from.

If you read the Wallaby topic you'll see that I did fine...

I did, you didn't. You went up on a shoddy, dangerous, noncompliant, unregulated configuration in, I'm guessing, zilch air and didn't lock out, had fun, got away with it - just like virtually everyone does virtually all the time.

...and now I'm dabbling my toes in the world of towing.

There is no aspect of this sport in which it's a good idea to "dabble". This is what Jason Rogers posted a dozen hours after our mutual friend banned me from his Merry Band of fellow SH*THEADS...

2009/11/10

Well I think he's probably right that there is a problem. I don't know if what he proposes is the right solution, but it's better than mine.

I looked at the stats, I looked at the caliber of pilots who were dying in tow accidents (far better than mine). I concluded towing is simply far too dangerous and gave it up.

I've never seen a fatal, but what I have seen scares the hell out of me, far more than any free flight issues. He proposes stronger weaklinks. I've been out towing with what were probably two G weaklinks. I've seen someone break one and do a full stall, tailslide and recover. His basebar skimmed through the two inch grass on the runway on the recover. I've watched another group with their own gear. I don't know what weaklinks they were using. Saw someone lock out at a thousand feet, stabilize in a vertical dive doing at least a hundred knots (maybe much more, he lost five to six hundred feet in two to three seconds) and break his link about two to three hundred feet up. He only just managed to pull out of the dive about fifty feet from the ground, tail wind with over 120 knots of ground speed. I never thought I'd hear a glider make a sound like that.

I loved towing. Really really loved it. To stand in a flat field, yell GO GO GO and then suddenly go roaring into the sky was an amazing experience. I just felt that every time I did it I was rolling the dice...

You focused on everything that went right on your tow, he focused on what can and - on rare occasions - DOES go wrong on established hang glider towing systems and equipment and - given that lay of land - made the only decision possible as a competent and responsible pilot. You've already started guzzling the Kool-Aid.

I've still got a lot to learn...

1. What? You already know how to fly a hang glider and I'm assuming you know how to aim it at a tug. There's not a whole helluva lot more to it.

2. Do you also know what instantly happens when you're holding a lot of pressure on or torquing the bar and take a hand off of it?

3. Do you know what happens to a plane on takeoff when its engine instantly seizes?

4. Any idea what a glider does when you hang a hundred pound sack of concrete from your keel a foot and a half in front of your hang point?

How are you gonna learn what you think you need to? Malcolm's gonna work to convince you that Two, Three, and Four really aren't issues, probably good things when you get right down to it.

What did you learn on that flight and outing?

You weren't the Pilot In Command of that aircraft but if it loses power at just the wrong time or suffers catastrophic failure of its control system you can end up just as dead as the guy who is. So did you read USHGA's aerotowing SOP's and preflight the system with those in mind? Or did you just trust Malcolm to have everything under control? (Rhetorical question.)

...and I appreciate the insights and questions that you've given me.

And I'd appreciate it if you'd get back to me with answers to some of those questions I've been asking - even/especially if the response undermines an assumption you've made and/or position you've taken. That's how we learn stuff.

I hope to be doing lots of flying, but if there's some down time then I'd like to do some of the tests that you've suggested...

Those priorities are BACKWARDS.

George Worthington - 1979/08

I would urge every hang glider pilot in the United States to read "The Key to Self Regulation" in the June issue of Hang Gliding.

Please, let's keep the FAA out. Please, let's try to continue to be responsible and free.

1982/09/10

Scott Rutledge

But as George was 360ing, the inboard wing broke. It broke right in the air. And it looked like there was a puff of dust that came off it.

Rick Masters

We attempted CPR. Joey gave mouth-to-mouth while I worked his chest. Soon our clothes were soaked with George's blood. I think we both knew he was dead, we just couldn't accept it. It was George Worthington, after all. George was our teacher. George showed us how to do this stuff safely. George was immortal . . . wasn't he? George couldn't die. Not here. Not today. This was George's contest. This was the future of ultralights. Could ultralights have a future without George?

Those are all tow people who ain't around no more either 'cause the flying was prioritized over the testing or the testing was done but the implications of the results were ignored.

...just for my own curiosity and interest...

Yeah? You think this is just for your own curiosity and interest? You don't have the slightest clue what's really riding on this stuff. Ya know the difference between a baby stroller and US hang glider tow equipment? The baby stroller's gotta adhere to some minimum safety standards.

2010/12/13

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).

Take a hint from Zack.

(I'm an engineer by profession and inclination)

And he'll be the first to tell you that he sucks at engineering - and is real minimal on the inclination issue as well. But he's getting the big picture pretty good.

As I wrote on the Wallaby topic, I was very happy with the experience. It was a great little flight, and I'd like to thank Malcolm for making it so easy.

Classic Stockholm Syndrome - MAJOR killer in this sport.

...but he made me do most of the flying!!

When I did winch, boat, people, aero, platform, static, step, and balloon I did ALL the flying - by myself. I've got this sneaking suspicion that the people who control towing wanna convince pilots that there's something mysterious and radically different from free flying that can only be understood and safely controlled by introduction through a series of expensive tandem hops.

I was a little nervous at first, but I figured he knew what he was doing ... and he did.

No. He didn't. Just 'cause you survive a tow with someone doesn't mean he knows what he's doing or runs a safe operation.

I'm gonna make some assumptions here which I'll happily retract and apologize for upon receiving contradictory information.

1. The tow mast on the Dragonfly has a breakaway built into it 'cause Bobby felt that people too stupid to follow weak link regulations deserved to live. This breakaway is dangerously understrength for lotsa solo gliders (mine, for example) - let alone tandems.

2. The regulations state that you hafta have a weak link on the front end of the towline. There was no weak link on the front end of the towline. There was a weak link on or near the top end of the bridle. If that weak link blows and the bridle wraps before clearing the tow ring the tug - and its release - are no longer weak link protected. If the tug driver had a weak link on the bottom end of the bridle as well, the tug - and its release - would still be weak link protected. The reason that tug drivers don't put weak links at either the front end of the towline and/or both ends of the bridle is because tug drivers don't put weak links at either the front end of the towline and/or both ends of the bridle.

3. The regulations state that you hafta have a weak link on the back end of the towline. There was no weak link on the back end of the towline. There was a weak link on one end of the primary bridle. If that weak link blows and the bridle wraps at the tow ring there's another weak link on one end of the secondary bridle. If that weak link blows and the secondary bridle wraps at the bottom end of the primary bridle you're screwed. You could have weak links on both ends of the secondary bridle but glider drivers don't put weak links on both ends of the secondary bridle.

4. You had a triple strand weak link on the tug's bridle and a quadruple on the tandem's. Which one do think the regulations say is SUPPOSED TO BE stronger, which one do think actually IS stronger, and can you envision any possible downsides to suddenly find yourself with 250 feet of slack Spectra draped over your basetube fifty feet over the upwind end of the runway?

axo - 2009/06/20

I always check my spinnaker shackle hook and the cable. Mine is still pretty much new and has worked perfectly.

But I have seen others fail twice and one of them was during one of my training tandems. I just kept hitting the brake lever for a few seconds in WTF mode, and the instructor used the barrel release.

5. You had a spinnaker shackle release with a cable lanyard going to a bicycle brake lever on your starboard downtube. That's one of the stupidest most dangerous pieces of crap ever deliberately put on an airplane. It would take a book to describe everything that's wrong with it. It's been a significant factor in three deaths I can name. In REAL aviation it would never have been allowed off the ground. In halfway sane bozo aviation it would've been permanently grounded after the first time it malfunctioned. But, hey, this is hang gliding so we just back it up with another unbelievably stupid dangerous piece of crap and send the pilot to some asshole like Tracy Tillman so he can pretend to train him not to ever get into a situation in which it's gonna become an issue.

6. The anchor point for the primary release was on the keel a foot and a half in front of the hang point.

7. Malcolm had a bent pin release coming off of one or both of his shoulders.

8. Malcolm tells you to release but you just kept hitting the brake lever for a few seconds in WTF mode, Malcolm pries a bent pin release open but the bottom end of the bridle ties itself to the tow ring. What do you think the glider's gonna do with maybe a couple of hundred pounds pulling on the fore keel section, what do you think you're gonna do about it, and how much time do you think you're gonna have to do it?

After we pinned off...

After you pinned off the entire issue of towing became one hundred percent irrelevant.

It was amazing to me (as a foot launch pilot) how quickly - and easily - we could make a flight.

Yeah. And everybody ALWAYS focuses on that. And everybody totally forgets the issue of how we could make the flight SAFE.

The landing was smooth and on the wheels.

And ya have any idea how many gliders we've crashed and people we've injured, crippled, paralyzed, and killed 'cause we insist on them landing on their feet?

Regarding the bent/straight pin issue, I didn't even check.

...(if there is one)...

Bart Weghorst - 2011/02/25

Most of the time. But I've had it once where the pin had bent inside the barrel from excessive tow force. My weaklink was still intact. The tug pilot's weaklink broke so I had the rope. I had to use two hands to get the pin out of the barrel.

IF there is ONE? How many do you think you need?

The barrel release wouldn't work because we had too much pressure on it.

Is two OK?

It's SHITT. PERIOD. It's no freakin' where close to a quarter of what it's supposed to be. And we didn't find that out by putting it in the air five hundred thousand times. We knew that from MY bench testing. Or just looking at it.

Note also that there's NOTHING in the regulations to support the positions of a**holes like Jack and Head Trauma that a release ever needs to go into the air to fulfill the requirements or accumulate statistical data.

2. This isn't about CHOICES. USHGA agreed to adhere to a set of standards to make aerotowing (somewhat) safe(r) in order for the FAA to allow us that privilege and then just went ahead and did whatever the phuck it felt like - and the FAA obviously doesn't give a rat's a** about my nephew's life either. USHGA and Malcolm said "we'll do this if you let us do this". They lied. So how is Malcolm any better than Davis, Jack, or Head Trauma?

...so I was fine just going with their standard procedures.

THEIR STANDARD PROCEDURES? If you're in a gang neighborhood and you want fifty bucks for a nice meal do you just shoot somebody in the back of the head and take his wallet 'cause that's the standard procedure in that part of town? If you're in South Africa with a nasty case of AIDS you wanna cure do you just phuck the nearest thirteen year old virgin 'cause that's standard medical practice in that neck of the woods?

Chicago Sun-Times - 2005/10/06

Four weeks after a horrific hang-gliding crash killed two people in LaSalle County, one victim's family is demanding answers.

Jeremiah Thompson was killed Sept. 3 while on a tandem hang glider, learning the hobby from Arlan Birkett, owner of Sheridan-based Hang Glide Chicago.

An airplane towed the hang glider into the air, with plans to reach 3,000 feet before the cable was released and their tandem hang glide began, an attorney said.

But two hundred feet into that ascent, the cable snapped, and the hang glider plummeted to the ground, smashing to pieces and instantly killing Thompson and Birkett.

On Wednesday, Thompson's family filed a negligence lawsuit against the company, demanding unspecified damages but also hoping to find out how the crash happened.

"They're two hundred feet in the air, and while normally they would glide to the ground, this hang glider nose-dived to the ground," attorney Matthew Rundio said. "We need to find out why that happened."

We KNOW why that happened.

Manned Kiting
The Basic Handbook of Tow Launched Hang Gliding

The tow line should be about 125 feet long and made of 2000+ lb. material such as 3/8" polypropylene.

We knew over thirty years prior why that was gonna happen. But, hey, it's fine 'cause they were just going with their standard procedures.

Now if I start making many many flights, then those statistics will begin to matter...

So it's OK to play million cylinder Russian roulette a few times when there's another couple dozen enthusiasts at the club and they're taking a lot more turns than you are. Yeah, I can follow that logic. If my nephew goes down there for a week for a crash course you're only subjected to a thirtieth of the risk he is.

...and I'll be asking questions as I progress.

Why bother?

I called and talked to the producer sharing the people's experiences and concerns. I inquired to what tension their releases were tested to but he refused to say, just aggressively stated they never had any problems with their releases, they were fine, goodbye, click. Another person tested one and found it started getting really hard to actuate in the range of only 80-100 pounds as I vaguely recall.

"Hey Reynolds Tobacco, the Surgeon General's been saying stuff about cigarettes and lung cancer. Anything to it?"

"Oh, PULLEEEASE!!!"

"Yeah, that's what I figured. You guys are the greatest! Keep up the good work!"

But overall, I was very happy with the flight and the park and the staff. I hope I can get my aero tow rating there in the coming weeks or months.

You're already in bed with them. They give you a little fix, you get high and have a blast, then you come back for a little more. Everyone's friends with everyone and who really gives a phlying phuck if some guy nobody's ever heard about - and shouldn't have been flying in strong thermal conditions like those anyway - gets killed once every three or four years?

What are the last three words in the title of this thread?

Thanks Malcolm!!

It could have been worse. It could have happened at ... the other place (but nothing happens there). 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. She was trying to dial 911. My friend suffered lower back injury.

Yep, thanks Malcolm.
