Eleven days now and no response to / acknowledgement of Lin's post - by ANYBODY (left) on The Bob Show. Both his and Nancy Tachibana's Tres Pinos / Mission incidents were of MAJOR historical importance for US hang gliding and this prolonged deafening silence on that rag screams volumes about just how much in the way of substance Bob has left.
I'm one hundred percent positive that Lin originally posted as a response at:

Rethinking towing
'cause Nancy's 2016/04/03 incident was Rick's trigger for launching the thread and Lin wasn't posting down in Bob's Basement "New Users Forum" - 'cause that's all he had access to - and referencing the topic Bob moved him back to after he was auto-bounced. And thanks bigtime for that bullshit, Bob. Really makes things fun for others who care to follow and comment on what very little you have going on over there. (And in case you haven't noticed - there's nobody anywhere else on the planet commenting on what very little you have going on over there. The local coffee shop owner running the worlds largest hang gliding community has outlawed all such references and there's nothing happening on Davis and Greblo. (And on the latter a serious unhooked launch incident appeared briefly then vanished without a trace - 'cept for here.))
That topic and the arrogance, cluelessness, stupidity of the douchebag who launched it infuriates me beyond description. Mike Lake dealt with him over there pretty well and I was dealing with him over here in this thread but a bit more needs to be said.

My research on towing clearly indicates the practice is one of the most dangerous things one can do on a hang glider.
A lot of people blame this on weight shift.
Weight shift certainly aggravates the problem but an awful lot of sailplane fatalities are also towing accidents, so there's more to it.
Essentially, the way I see it is towing may have its place as a last resort - for instance, where there are no hills within a couple hours drive.
Maybe advanced pilots can accept the risk, but I think they do it too easily.
Novices in training? H1s?? Hell, no.
Who talks a novice into towing? Commercial instructoes withtow operations, for the most part. There is a lot of money in it.
Who else benefits from tow training?
Why in the world are instructors training novices with towing equipment when training hills are within reach?
What this asshole is saying is that there are immutable risks of fatality associated with slope and tow launched hang glider flights and for the former it's X and for the latter - due to all the associated complexities - it's 12X. After three people rack up a total of 12X tow flights one of them's gonna be dead - and there's NOTHING we can do to lower that rate. (Likewise for the slope launchers. Even less room for improvement anywhere on that front.)
And let's just ignore the FACT that a mountain flyer is thirty times more likely to get totaled than an AT park flyer and just look at the tow launch incidents.
Was anything that happened with either of the last two fatals at Quest a big fuckin' surprise? Did Challenger blow and Columbia burn up 'cause - even though everyone was doing everything as right as possible - space launches and re-entries are inherently dangerous? Every mission we're just rolling dice?
Manned Kiting
The Basic Handbook of Tow Launched Hang Gliding
Daniel F. Poynter
1974
"A bad flyer won't hurt a pin man but a bad pin man can kill a flyer." - Bill Bennett
"Never take your hands off the bar." - Tom Peghiny
"The greatest dangers are a rope break or a premature release." - Richard Johnson
But then half a dozen years later Donnell came around and got everything properly sorted out.
- There was:
-- no such thing as a bad pin man, just crappy pilots. (Most of them using stronglinks trying to trade off safety for the sake of convenience.)
-- absolutely no disadvantage to taking a hand off the bar 'cause we had a center of mass bridle that would continuously autocorrect for roll.
- The only problem with rope breaks and premature releases was that they weren't premature enough. And all we had to do was install a one G max Infallible Weak Link which would keep us from getting into too much trouble and guarantee a safe recovery.
And you were all totally on board with all that crap 'cause you did all this extensive research on hang glider towing and found nothing wrong with any of it. Also nothing wrong with Seventies era towing 'cause you had no criticism of that either. Towing is towing ferchrisake. No matter how things are being conducted your extensive research on towing clearly indicates THE practice is one of the most dangerous things one can do on a hang glider. Right up there with not getting your flare timing properly perfected prior to getting signed off on your Two.
Reminds me a lot of:
Towing Aloft - 1998/01
Weak links very clearly will provide protection from excessive angles of attack, high bank turns and the like for this form of towing.

To understand my thinking, you need to know that I am a purist.
And just imagine where this sport would be without people understanding your thinking and level of purity. I don't give a rat's ass whether or not people understand my thinking or level of purity...

Weak link breaks?
Dan Tomlinson - 2005/08/31 00:33:01 UTC
Tad's post is difficult to read but I've seen his work. His release mechanism is elegant in its simplicity and effectiveness.
Scott Wilkinson - 2005/08/31 11:47:53 UTC
Tad's point of view is irrelevant to me--there's no intelligent reason to ignore his work if it is superior to what we're all currently using. (The sport would never improve if everyone thought "if it ain't broke, don't fix it.")

Unhooked Death Again - Change our Methods Now?
JBBenson - 2009/01/25 16:27:19 UTC
I get what Tad is saying, but it took some translation:
HANG CHECK is part of the preflight, to verify that all the harness lines etc. are straight.
HOOK-IN CHECK is to verify connection to the glider five seconds before takeoff.
They are separate actions, neither interchangeable nor meant to replace one another. They are not two ways to do the same thing.

Aeronautics is all about Newtonian physics and if we need to start understanding a particular individual's thinking on any particular issue we're doing religion. And that's totally fine with all you dickheaded purists.
I believe hang gliding in its purest form involves footlaunching off mountains.
Yeah, you're so fucking pure that you've never been within five hundred miles of a major tow operation. You learned everything you really needed to about tow launches from flying in the Owens forty years ago. Perish the thought that you should ever once hop on a truck tow platform or AT cart in sled conditions and taint yourself with a milligram's worth of actual experience. Then all us tow launchers would have no one pure enough to tell us what a bunch of totally clueless dickheads we are for spending our weekends at Ridgely and leaving cobwebs growing all over the High Rock ramp.
And by the way...
Hang gliding didn't evolve from or through footlaunching off mountains. And I'd maintain that it went substantially backwards when it took that route. (And towing went substantially backwards when Hewett got involved and established it...
Donnell Hewett - 1980/12
Skyting requires the use of an infallible weak link to place an absolute upper limit to the towline tension in the unlikely event that everything else fails.
Now I've heard the argument that "Weak links always break at the worst possible time, when the glider is climbing hard in a near stall situation," and that "More people have been injured because of a weak link than saved by one."
Donnell Hewett - 1982/09
In addition to the above mentioned roll and yaw tendancies, there is some sideways force on the pilot due to the body line. This is illustrated below:
As can be seen, this sideways force tends to pull the pilot over to the correct side to make the glider turn naturally in the proper direction.
...as a branch of his religion.)
Yeah, we can agree that paragliders DO collapse in thermal turbulence and when this happens low enough there won't be enough time for either recovery or a parachute deployment. So let's say there's a defective reserve in circulation that requires an extra three seconds to inflate. You see a PG guy about to launch with one. Do you say NOTHING 'cause paragliders are twelve times as likely to get one killed as a mountain launched hang glider and your purity prevents you from saying or doing anything to dial things down a notch or two?
Nancy didn't get killed 'cause Mission lured her off the training hill so's they could make megabucks hauling her up off the flats on a line. Nancy got killed 'cause the Mission guys are incompetent douchebags using total shit state-of-the-art equipment and procedures.
I didn't start towing - as a Three skilled Two and Kitty Hawk dune instructor at the tail end of the era when the connection was glider-only - 'cause any commercial instructoes withtow operations talked me into it. I started towing 'cause we had a Yarnall winch and I was champing at the bit to get airborne in as many venues by as many means as possible. And I was having a BLAST doing all that.
Rick Masters - 2016/04/12 20:04:03 UTC
I am not calling for no towing, ever.
Who gives a rat's ass - one way or another - what you feel like calling for? What credentials are you supposed to have to be establishing or recommending policy for anyone else?
Advanced, experienced, skilled pilots can evaluate the risk.
Advanced, experienced, skilled pilots can go fuck themselves. Bo Hagewood and Zack Marzec were advanced, experienced, skilled pilots and neither ended up in very good shape - the former on multiple occasions. Jeff Bohl was an advanced experienced skilled Hang Four AT comp and ace airline pilot. And none of that did him any good 'cause he tried to launch with several marginal issues in play on total crap equipment and made a small mistake with a duration of under a second that would otherwise have been a total nonissue.
You don't need to be advanced, experienced, skilled for anything that matters much in this sport. You need solid Two level COMPETENCE. And a COMPETENT pilot doesn't EVALUATE risk - he DOESN'T TAKE risks. "Well, there's only a one percent chance of me locking out and slamming in on this launch 'cause I'm really advanced, experienced, skilled. Let's GO FOR IT!" You don't make it through a good weekend without killing someone working on that model. And every actual competent pilot knows that and your last sentence tells us all how you fit into this picture.
I fit that description...
No shit. To a fuckin' T.
...and I have chosen never to tow.
Also to never fly for the past four decades. And never been so much as scratched in a flying incident within that period - a record which most of us muppets can only dream of matching.
Others who I respect choose to tow pretty regularly.
1. Which end? Dave Farkas, Corey Burk, Gary Solomon, Bobby Bailey, Tex Forrest, Lisa Kain, Mark Frutiger, April Mackin have all done fairly well for themselves over the years. Really surprising 'cause for every launch one of us muppets makes the front enders must do a couple hundred. And they're the Pilots In Command so have two planes to fly each launch.
2. Can we get a list of the others whom you respect? I want to add them to my list of those I don't - in the unlikely event they're not already on it.
They figure they can deal with whatever goes wrong.
Go fuck yourself. They all bloody well know they won't be able to do shit on their total crap excuses for equipment. And I know that even with the best engineered equipment on the planet (which I had to design and build myself) I won't be able to deal with "whatever goes wrong". And the reason that - even with total crap equipment - the launch crash rate (excluding Standard Aerotow Weak Link inconveniences) is so close to zero that it's not worth talking about the difference is because the environment is so ultra safe.
Tug driver plus two man launch crew - neither of whom is performing a function any more critical than signaling the tug to floor it.

about seven seconds since commencement of roll we're virtually bulletproof. We prone out on the cart, grab the hold-downs, signal the tug, stay pulled in a little, wait till the glider trims and we get tons of airspeed, nose up a little and lose the cart. Tell me how one manages to fuck that up - preferably with the inclusion of a video illustration.
We each look at the same thing and come to different decisions.
Then someone to everyone is wrong - and probably stupid.
Nobody who thinks the way I do has ever been killed towing.
Implying that individuals who think the way you do HAVE BEEN killed in mountain launch incidents. And I can name one of them: 1982/07/31 - Bob Dunn - Plowshare Mountain - unhooked launch. Don't see many of those at platform and AT ops.
But an awful lot of people who think the opposite are no longer around.
Name them. Show us how right they were doing everything but got killed anyway 'cause towing is such an inherently and insanely dangerous means of getting a hang glider airborne.

Anybody who doesn't recognize that launch environment as several hundred times more dangerous than what one has at ANY AT op has total shit for brains.
