...pro tow bridal, huh Mark?
I was surprised (though I shouldn't have been) at how hard it is to turn away from the tug after cutting away. Close to half VG and all...
Like, REALLY different.
I will have to pull in for speed/response quite a bit more aggressively than before.
Why don't you just pull in BEFORE you release? Oh... Right. Never mind.
Nice to know that there will be natural separation in case I'm behind the curve...
What? You're just figuring that out now, Mark? A decade and a half of flying Ridgely and you're just now realizing that when 125 pounds of thrust is subtracted from the glider it goes slower and when that same 125 pounds of thrust instantly becomes available to the tug it goes faster? That the tug starts getting smaller instead of staying the same size? When was the last time the water was tested at that place?
But still, need to do better!
Yeah, we've got way too many gliders flying into tugs as it is. Keep focusing on the biggies. (Anybody hear anything 'bout how John Claytor's doing?)
Also very good to hear Jim's thoughts about staying with the turn when released in lift. That certainly expands the options!
You are SO LUCKY to have Jim doing your thinking for you. A world treasure right there in your own backyard.
Suck my dick, Mark.

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.
An intellect as keen as yours AND a lot of time to think! Are you sure you have enough closet space to keep packing in all those Nobel Prizes?
Pilots often apologize for staying on tow.

Then again, Russell Brown had us double up behind him after six breaks in a row at Zapata. We couldn't figure out why we had so many breaks so quickly. Maybe just coincidence.
...fifty feet sometimes!
I've never understood this.
Well you just put your keen intellect to work for another couple years. I have no doubt whatsoever that you'll have some truly remarkable breakthrough insights into the issues.
Often it's staying on tow through lift.
That was probably the issue with this:

pro tow set-up
Ryan Voight - 2009/11/02 23:55:05 UTC
Ummm... If you're holding that much pitch pressure, popping the weaklink and flying away should be easy as blaming a fart on the dog
Ryan Voight - 2009/11/03 05:24:31 UTC
It works best in a lockout situation... if you're banked away from the tug and have the bar back by your belly button... let it out. Glider will pitch up, break weaklink, and you fly away.
During a "normal" tow you could always turn away from the tug and push out to break the weaklink... but why would you?
Have you never pondered what you would do in a situation where you CAN'T LET GO to release? I'd purposefully break the weaklink, as described above. Instant hands free release
Jim Rooney - 2009/11/03 06:16:56 UTC
Please do not think for an instant that that thing isn't going to let go. It's going to snap so fast that you won't realize what happened till after it's happened.
As for being in a situation where you can't or don't want to let go, Ryan's got the right idea. They're called "weak" links for a reason. Overload that puppy and you bet your ass it's going to break.
You can tell me till you're blue in the face about situations where it theoretically won't let go or you can drone on and on about how "weaklinks only protect the glider" (which is BS btw)... and I can tell ya... I could give a crap, cuz just pitch out abruptly and that little piece of string doesn't have a chance in hell. Take your theory and shove it... I'm saving my a$$.
The only thing I can come up with is that they somehow feel like they're "tying up the tug", but I often hear the same thing when there is no one else towing?
Wanna see what ties up tugs...

Due to the rough conditions weak links were breaking just about every other tow and the two tugs worked hard to eventually get everyone off the ground successfully.

An OK Day at Ridgely
Matthew Graham - 2014/06/09 01:51:11 UTC
I got on the flight line at a little after 1pm behind Sammi. She had a sledder. Then the tandem glider called rank and went ahead of me. The tandem broke a weak link and it took a while to sort out a new weak link. I finally towed around 1:30 and also broke a link at 450'. Back to the end of the line. Actually, my wife Karen let my cut in front of her. Bertrand and Sammi towed again. Each having sledder. The cirrus had moved in and things did not look good. Again I arrived at the front of the line only to have the tandem call dibs. And then the tug needed gas. I thought I would never get into the air...
...and everybody else - motherfucker?
Here's the deal....
You love to fly right?...
Well, kicking your teeth down your throat would be my FIRST choice, but... Yeah.
..well, so do I.
And aren't we so very fortunate to have someone with an intellect as keen as yours with all that time to develop it, appoint himself Pilot In Command of our planes, tell us what equipment we can and can't use, and enlighten us with amazing insights that no one in the entire history of aviation has ever thought of before.
So it's pretty impossible to "waste my time" in the air. We're flying!..
One of us is. When a Rooney Link increases the safety of the towing operation for me at fifty feet:
- I have to sled out and land a few hundred yards down the runway, haul my glider, harness, and ass back to the launch line, replace my safety device, wait for a launch cart, reconfigure, roast in line while a couple of tandem bucket listers to get one of their lifetime goals checked off, get a cart monkey to approve my setup, roll back out to the launch point, hook up, pray for better results using the exact same Rooney Link...
- You get to keep your stupid ass strapped in, do a little go-around, land, hook up the next waiting glider, continue as if nothing happened. Takeoffs and landings are the fun part for you so Rooney Links MAXIMIZE your quality playtime at the expense of destroying mine - and it's all on MY dime. AND...

Tad's Barrel Release and maybe an alternative
Jim Rooney - 2008/02/14 01:37:28 UTC
(3 tows/year) The crux of everything Tad says here.
He is the ultimate sideline quarterback.
Yet he is constantly insulting and condescending to anyone that doesn't agree with his assumptions and conclusions.... which are based on a horrible lack of experience.
It baffles me that people even listen to him.
...you get to blather on even more about how you racked up more airtime last Saturday than T** at K*** S****** did in the last five years.
I'm in happyland.
- And your good friend Zack Marzec is in Never Never Land.
- 'Cause YOU'RE on a gas guzzler. HANG GLIDER pilots tend not to be very happy driving tugs 'cause the better conditions there are for flying hang gliders the less the chance the tug driver has of getting a piece of them in a soaring aircraft.
On the ground is a different story.
Yeah. We know ALL about the ground...

Jim Rooney - 2011/08/28 19:39:17 UTC
Weak links break for all kinds of reasons.
Some obvious, some not.
The general consensus is the age old adage... "err on the side of caution".
The frustration of a weaklink break is just that, frustration.
And it can be very frustrating for sure. Especially on a good day, which they tend to be. It seems to be a Murphy favorite. You'll be in a long tug line on a stellar day just itching to fly. The stars are all lining up when *bam*, out of nowhere your trip to happy XC land goes up in a flash. Now you've got to hike it all the way back to the back of the line and wait as the "perfect" window drifts on by.
I get it.
It can be a pisser.
But the "other side"... the not cautions one... is not one of frustration, it's one of very real danger.
Better to be frustrated than in a hospital, or worse.
No exaggeration... this is the fire that the "other side" is made of. Best not to play with it.
...pigfucker.
I'm sure you can relate to not wanting to wait around on the ground while roasting in your harness.
You don't use a harness like we do, right? You just plop yourself in a cushioned seat and buckle a couple straps, right? No full face helmet or clothes for sustaining at cloudbase...
A bit is necessary, but after a while it gets pretty miserable.
And I'm sure that brings YOU a great deal of misery just thinking about OUR misery.
So you try to be as efficient as possible.

weak links
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.
My world is not too dissimilar.
Fuck you and your goddam world and all the other total pieces of shit inside it.
Sitting on the ground idling while backing in the sun is a less than pleasant place to be.
Try alternating by sitting on the ground idling while fronting in the sun. Distributes the burn a bit more evenly.
I'd much rather be either in the air or hiding in the shade under the wing.
Wanna REALLY get out of the sun? I've got ALL KINDS of suggestions for ya.
So my advice is to either be ready, or wait.
Would being ready include making sure you've got a reliable means of transmitting thrust from the tug to the glider? Just kidding.
If you're not ready, that's fine. Don't push up to the ready-line until you are. I'll land and pull in, turn off the engine, grab a water, hide under the wing, take a leak or any number of little things that I can't do waiting with the rope tight and the engine idling.
Keep your keen intellect occupied with solving even more of hang gliding's many problems.
Pulling up when your ready helps you as well. Not only do you have a much happier tug pilot (happy tug pilots are better at finding lift), but I also have a better idea of what's going on with the air as I was just there a second ago.
Yeah. Us too. At fifty feet it's almost always nothing that was going on.
Being ready also makes the line move much more efficiently which benefits everyone. I have a far better chance of putting you in lift and getting your buddies into lift with you. When things aren't running well, it gets a lot harder to do so.

Weak link question
Jim Rooney - 2008/11/25 19:21:57 UTC
Brian,
While I appreciate your quest for the perfect weaklink, didn't we cover this already? (Again?)
Are we to go down the road of debating the quality standards of greenspot again?
Ok, for review, it doesn't matter.
Why?
Because you have nothing else.
Do I have to review why we don't tow handmade gliders?
Listen we're all perfectly aware that greenspot is not laser calibrated to 130lbs. It's bloody fishing line. Get over it. Are you flying below your perfect numbers as a heavy guy. Yes. Yes you are. Get over it.
Why?
Because it's all you've got.
Why lower numbers? Because your choice is lower or higher... and higher is more dangerous than lower.
Plain and simple. Janni, 1G, but please stay.
Now, my turn.
Name one commercially available strength rated material that can be used as a weaklink OTHER than greenspot.

Davis Straub - 2013/02/09 16:45:39 UTC
I am more than happy to have a stronger weaklink and often fly with the string used for weaklinks used at Wallaby Ranch for tandem flights (orange string - 200 lbs). We used these with Russell Brown's (tug owner and pilot) approval at Zapata after we kept breaking weaklink in light conditions in morning flights.
Isn't there ANYBODY who's gonna kick this motherfucker's teeth down his throat?
So if you want to move things along, don't worry about staying on tow.
Think about it... how much do you slow things down by sinking out?
The way to "not tie up the tug" is to be ready.
How STUNNINGLY CONSPICUOUSLY ABSENT from the discussion this elephant is. Must've been taken out by ivory poachers.

Towing question
Martin Henry - 2009/06/26 06:06:59 UTC
PS... you got to be careful mentioning weak link strengths around the forum, it can spark a civil war
Brendon McKenna - 2009/06/26 13:20:41 UTC
Hey Martin,
I have seen the odd discussion about weaklinks here on this list... LOL We definitely don't want to go there!
I think I understand what's going on here.
- Just a month shy of three years ago the Rooney Link was totally acknowledged as the primary soaring opportunity killer but we had to use it because the consequences of using fishing line that DIDN'T blow all the time when the tow was totally under control were probably just too horrible to think about.
- Twenty-six months ago on the issue we had the biggest load of pigshit ever to appear in print published in the national magazine.
- Seventeen months ago we had a blindingly obvious Rooney Link precipitated death which was hands down THE most controversial fatality in the history of the sport. Russell Brown had previously been forced to authorize double Rooney Links in order to be able to get gliders airborne, Morningside had previously decided they were happy with two hundred pounds (slightly stronger than 130), accepted standards had previously changed.
- We totally humiliated the Rooney Linkers. Every time they opened their mouths we buried them under avalanches of their previous stupidities, inconsistencies, contradictions, lies. That was the absolute collapse of the Ponzi scheme. Nobody went to prison but all the snake oil salesmen learned the hard way that they could never again attempt to make a favorable claim about their product.
- The lower ranks - dregs like Marc Fink, Matthew Graham, Cragin Shelton, Dan Tomlinson, Kinsley Sykes, Paul Hurless, Craig Hassan, Richard Bryant - with all their noses permanently glued up Industry ass - learned what would happen to them if they said anything in defense of the scum in with whom they'd long ago thrown their lot.
We've entered a period of hang gliding history in which it's one hundred percent taboo for ANYONE at ANY level to attempt to say ANYTHING of substance on weak links. Hang gliding is faith based aviation. It's just another crappy bullshit religion and crumbles under any kind of scrutiny just like any other crappy bullshit religion. Donnell Hewett's Skyting Theory voodoo was embraced by a hang gliding culture not IN SPITE OF its being a crappy bullshit religion but BECAUSE OF its being a crappy bullshit religion.
The Infallible Weak Link - which is the only thing standing between hang glider towing culture and the unspeakable evil of competence - has been hang gliding towing culture's God for a third of a century. When your God has been irrefutably proven to be a total fabrication by a bunch of historians, astronomers, evolutionary biologists, paleontologists, climatologists, mathematicians, physicists you don't debate these people claiming that it's just a piece of fishing line that breaks before your glider does - you denounce, shun, ostracize, exile, excommunicate them and keep going to church, tithing, sending you kids to Sunday school every weekend.
On every front in which one or several of us have mopped the floor with the high priests of hang (and para) gliding discussion of weak links is dead.
Pre Marzec a regular Joe would have a question about weak link strength every now and then and trigger a civil war - just as Martin said. That era is OVER.
The hang gliding Industry has gotten backed and painted itself into an impossibly tight corner and the only options for it are to stay there or admit that it was flat out WRONG from the git-go (and his been lying its ass off to keep it covered ever since).
And when was the last time The Industry ever admitted it had been wrong about ANYTHING?

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."
That was it. Over thirty one years ago. Move the bottom attachment from the basetube to the pilot. AND, of course use:
- a Center Of Mass system which autocorrects for roll
- an Infallible Weak Link to prevent lockouts for when the Center Of Mass system DOESN'T autocorrect for roll
- a release within easy reach because with all that other stuff going for you it would be stupidly superfluous to give you the capability of blowing tow while controlling the glider.
It's in the USHGA Bylaws and Mission Statement that every time you admit you were wrong about one thing you hafta bundle at least three new items of total deadly crap to balance things out.
The Birrenator will NEVER be a certifiably insane death trap because Peter invented it and Pat Denevan's using it.
Whenever a commercial interest person kills someone by violating an SOP *HE* won't be removed from hang gliding - the SOP WILL. Constant unstoppable lowering of the bar.
ANY progress that requires anybody who's ever made a buck from hang gliding to admit that he's been wrong or be identified and declared as having been wrong about ANYTHING will NEVER happen.
And any solid theory, procedure, equipment equivalent to anything from a century's worth of conventional aviation that doesn't come from a significant commercial interest - ain't gonna happen dude.
And nothing's gonna come from a significant commercial interest 'cause - Catch-22 - that would be an admission that they'd been wrong about what they'd been saying, doing, using in the past.
Legal range weak links which allow mid to heavy range gliders to get airborne and varying in proportion to either flying weight or glider capacity... WHAT? Are you TOTALLY NUTS or sumpin'? Don't you think we know what we're doing - you wacko muppet?
