When was the last time you read a:
- fatality report which discussed the victim's long history of tight grip related incidents at altitude and minor launch and landing crashes?
- post by a new pilot talking about the problems he was having related to his tight grip and efforts to deal with the issue?
- announcement of a light grip clinic the first Saturday in April to help new pilots properly prep for the upcoming season?
- public expression of the gratitude of a new pilot for his ace instructor reminding him to always maintain a light grip?
This is pure unadulterated bullshit. Yeah, if you see a Day One, Flight One student standing at he top of the hill with a death grip on the bar the chances of a positive outcome are not gonna be great. He's also gonna have a higher than normal heartbeat. So why not:
The problem is that the student is scared and you don't solve it by addressing a symptom. "You won't get anywhere recovering from your chickenpox until you decide to stop producing those nasty red spots all over your skin. Let me know when you're willing to cooperate with me. Now if you'll excuse me I have other patients waiting."
There is no cure for chickenpox but the cure for a tight grip - if there's gonna be one - is to move the student down the hill, back down to flat ground if necessary.

Quest Air Aerotow FAQ
For several years when I started flying the local ridges after leaving the dunes my grip tended to be a little tighter than it needed to be because I was a little acrophobic. The only problem with that was that my flying was more tiring and I'd feel stiffer the next day. It was NEVER the slightest control or safety issue. The problem disappeared as I acclimated and started understanding just how brutally overstrength my bird was.
That process COULD have been accelerated by a good instructor - if such an individual actually existed in hang gliding - but telling me how important it was to maintain a light grip wouldn't have accomplished a whole lot.
- "Are you maintaining a tighter grip than you need?"
- "Yeah. Probably."
- "You're scared. You don't need to be. Let's talk about what it is that's scaring you."
An approach like that would very likely have helped. Now that I think about it... That's the conversation I had with myself that got me to where I needed to be.
Most of the "thought" process behind this "light grip" bullshit is that you can't hear the glider talking to you through your hands if you're clamped down three times as hard as you need to be, can't be getting that feedback, picking up on the subtleties of what's going on with the glider. Try this experiment...
- Take a competent Four level flyer and cut his hands off above the wrists with a light saber.
- Fit him with a pair of Luke Skywalker bionic replacements.
- Send him back up with the grip set to 0.8 aluminum crush level.
He's gonna be thermalling up indistinguishably with the rest of the swarm.
Fuckin' control bar doesn't TELL YOU anything any more than a steering wheel or bicycle handlebars do. It's the tool you use to pull in, push out, torque left/right to keep/get the glider doing what you want/need it to. And you can detect bar pressure just as easily with a death grip as effectively as you can detect rope tension when you're maintaining a death grip while starting to lose a tug-of-war contest.
Remember back in the early Eighties when we decided full-face helmets would be a good idea? But we weren't gonna be able to hear the wind noise as well so we were gonna stall at a rate increase of thirty percent. (Stalls were still considered to be bad things back then.) Solution... Cut one inch diameter holes in the shell at ears positions - the ubiquitous Uvex helmets of the day. Great. Three hours of loud white noise to enhance one's flying experience for the day. Big help with radio communications as a bonus. I glued rubber disks over mine and lived with all the extra stalls I had as a consequence.

"Shit! That thermal just spun be back towards that rock pile to the left of launch. Must remain calm! Must maintain a light grip at all cost! This is where the outcome most depends on my expert training!"
This "light/loose grip/touch" crap is emblematic of the u$hPa / Industry campaign to discount the importance of hands on the basetube in glider control. For:
- launch leave the hands on the control tubes for a minimum of five seconds after clearing the ramp.
- landing put your hands at shoulder or ear height where you can't control the glider at a minimum of two hundred feet or the beginning of final - whichever comes first. And remember to let go and ball up before you crash.
- towing always fly with the release actuator within easy reach. Releases which allow you to blow tow with both hands on the basetube are all extremely dangerous 'cause they're complex and have extremely short track records.

too or instead? There is virtually no one in hang gliding who's ever had a bad afternoon when the critical moment wasn't immediately preceded by a dramatically increased heartbeat. Normal pulse, no crash. The logic and solution are inescapably obvious.As with all hang gliding, it's important to encourage a normal heartbeat.
The problem is that the student is scared and you don't solve it by addressing a symptom. "You won't get anywhere recovering from your chickenpox until you decide to stop producing those nasty red spots all over your skin. Let me know when you're willing to cooperate with me. Now if you'll excuse me I have other patients waiting."

...training bump yet. They're running the glider, practicing pulling it by their harnesses and correcting roll by weight shift without using their hands - and they still get help with flare timing.
Somebody please explain to me how you blow flare timing while propelling the glider forward.
- running full tilt in no wind
- running with all the power you can muster or standing still in 25
- standing still in zero
Is there some way you can punch too early and send the glider rocketing up into a whipstall? Kinda wish there were 'cause that would mean you could get in some decent training hill flights without the training hill.
If you're late on your timing is that gonna leave you running behind the glider headed for a power whack and broken arm?
Tell me how it's possible to have anything other than perfect flare timing when you're propelling or not propelling the glider into the wind or lack thereof on the flats.
Flare timing is used for stunt landings when the glider's in a skim bleeding off airspeed. I guess you could simulate a late flare by running up to full speed, slowing down, getting behind the glider, pushing out weakly - but I can think of lotsa better things you could be learning before getting properly airborne. A hook-in check comes to immediate mind.

Sometimes their equipment trailer, which contains the TV they use to play intro videos at the LZ, is stationed with the TV facing the simulator on that end of the field.

Which way will the glider roll?
Last year I went to a clinic in Utah hosted by Ryan Voight. Ryan's into aerial photography and on a down day we were discussing camera mounts. He had a mount that attached to the base tube and extended out a ways in front of the pilot pointing aft. He said you didn't have to counterweight it because as far as the glider was concerned all the weight was on the base tube where the mount attached. I wasn't sure about that and Ryan isn't the most trustworthy source with regards to physics but he apparently had experimental verification that was the case so I went with it. It never occurred to me to apply that same principle to our hang points.
It's well known that if you put a heavy camera on a leading edge out near a wingtip it will cause a roll tendency. If the camera was in the same position but mounted to a beam attached to the keel at the hang point instead of the leading edge it would not (I think). If that's the case, the actual shifting of weight that occurs in a roll can't be the cause of the roll because the pilot is still attached to the same point on the glider. For a true weight shift roll to occur the hang point would have to move laterally.
I never really understood why a tow rope pulling a pilot didn't cause a control input in the direction of the pull but just went with it...now it makes a lot more sense. So much for Pagen'sEven if I accept that shifting weight isn't responsible for a glider's response, there are still some things I'm not clear about. The control frame is fixed to the keel...what causes the left wire in your example to tighten? What causes the slop transference? If the roll is caused entirely by wing warping, how does differential wire tension effect pitch changes (which, to my knowledge, are not caused by wing warping)?When you move your body to the side, your weight increases the load on one wing and decreases it on the other wing. This makes the more heavily loaded wing move down to bank the glider.
By the way, this is the best illustration of wing warping I've come across:
http://ozreport.com/images/redheaddune/DSCF1906.JPG
I'd love to be able to capture it on video but it's not practical to mount a camera that can capture a glider's entire span.
Wow. I can't believe he said that. Regardless, we all know gliders tow better from the pilot than just the glider. Why is that?Donnell Hewett wrote: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.
Neither do I. Here's the best explanation I've found:TadEareckson wrote:I don't know this construction.remmoore wrote:Unlike flexes, the ATOS control frame is essentually non-structural. The control frame is just the "handle bar" for the glider. On it's carbon control frame gliders, AIR was able to incorporate the spoileron control wires into the control frame stabilization system, thus eliminating a set of wires. The ATOS still has rear wires, but the glider has 1/3 fewer wires than topless flexwings.Interestingly, spoilers create drag, so rigids that use them to roll supposedly don't suffer from adverse yaw.TadEareckson wrote:The stuff in the parentheses will cause the glider to yaw adversely but the sweep will take care of that problem for you.
At any rate, big thanks for the explanations. Even after a year you are still shattering the understanding of hang gliding concepts I've learned through instruction. Got any more bombs you haven't dropped yet?
Bob, thanks for your explanation as well. I'm getting closer.

That two hundred pound differential wire tensioning actuator suspended from the keel MOVES - within the "closed system". It torques left and right and the loading and distortion of the wings alter in sync. The wings are asymmetrically loaded and roll increases for as long as the input is held. No muscle, no torque, no asymmetrical loading, no more aileron effect.

Also, just briefly touching on the whole torque/what makes a glider turn thing... I'll try to be kind and say that I find it most unlikely that our gliders turn because of the minimal rolling torque pressures we are applying through the control frame. I will also present evidence of that silliness- Follow the forces! To move your weight left, you are pushing the base bar to the right. The base bar isn't able to go to the right, primarily because of the left side wire. Tension on that wire might be increased, but the cross-bar/leading-edge junction isn't pulled toward the corner bracket, primarily because of the upper side wire running to the kingpost. Possibly tension on that is increased, but the top of the kingpost isn't able to move toward the left cross-bar/leading-edge junction because of the upper right flying wire. Keep going in your mind, until you get back to the base bar... (it's a closed system folks).
Instead, what causes a glider to roll is an imbalance in aerodynamic forces. When hanging centered and neutral, the center of gravity (the point at which gravity acts on the pilot/aircraft as a single combined unit) is in alignment with the center of lift. Move your body to the left, and now gravity is acting more on the left, while lift is now acting to the right of where gravity is acting. YES, THAT IS ROLL TORQUE, TOO. But it's caused by aerodynamic forces, not us muscling the glider to roll around us!
"evidence of that silliness"
Tormod Helgesen - 2016/04/19 09:06:14 UTC
I see torque mentioned as a means of controlling a hangglider. It's true that while you're shifting your weight you're putting a force/torque into the system. BUT that force is only for a split second AND it's nulled by the force you use to stop that motion. (Newtons 3rd, for any force there is an equal and opposite force.) Remember you're suspended from the center of the glider with a flexible strap so you don't have leverage to move the controlbar, you're only able to move your body relative to the bar.
So for all practical purposes, the only pilot induced force controlling a hangglider is weight-shift.
Tormod Helgesen - 2016/04/20 06:05:53 UTC
No, because of Newtons third law again. The force you're applying to the control bar is opposed by an increase in the tension in the hang strap so the net leverage is zero. The weight has shifted though.
Tormod Helgesen - 2016/04/20 20:33:36 UTC
Brian scharp: Please show a video of you lifting yourself by your hair. It's basicly what you're advocating here.
Tormod Helgesen - 2016/04/21 05:52:50 UTC
At least you understand that lifting yourself by your own hair is impossible, that's a beginning.
Tormod Helgesen - 2016/04/22 09:16:19 UTC
Give up! For you own sake.
I think the problem is that your opponents believe that you need leverage to steer the hangglider. They can't grasp the fact that while airborne you're part of a closed system so that whatever force you use to move your body is opposed by an equal force. To produce any leverage (or torque) you'll have to fix the harness to the bottombar and rotate your body inside the harness, mimicking an engine and propeller. To add to the confusion someone is mixing in towing which is a totally different thing as it's a powered system. I think you've encountered a unsolvable case of the Donning-Kruger syndrome as your opponents simply refuses to educate themselves.
Tormod Helgesen - 2016/04/26 20:25:56 UTC
Maybe I'm just plain stupid because I don't understand how one can excert any torgue on the controlbar while not in contact with terra firma? Except for that brief moment you actually start a movment (which is cancelled out when you stop moving).
Care to explain? Mr Scharp, aeroexperiments?
For you Jack Show dickheads who are unable to grasp the concept of roll control torque / differential wire tension 'cause you can't SEE any glider components MOVING...Tormod Helgesen - 2016/04/27 05:31:05 UTC
That's the force that returns your body to the center position but that force is opposed by the added tension in the hangstrap. You need a fixed point outside of the glider/pilot system to put any torque into the gliders controlbar, at least that's what I've learnt.

Since when has Mission EVER been the slightest bit interested in improving safety in ANY way?...even if it may help improve safety in some way.
Duh.Several things about the horrible tragedy on April 3rd at Tres Pinos came to light in the past few months. First and foremost, there has been zero investigation.
Fuck, it was just a hang gliding fatality. Somebody else dying doing what she loved. Get over it.As in NO ONE called the police.
What? Did something happen?There is no police report. NO ONE called the sheriff department. There is no sheriff's report. They have only begun to investigate a couple weeks ago after we called them on it. In what seems to be a vicious turn of events, the scene was very quickly cleared so as to make it look like nothing had happened.
It's a dickhead magnet and you get what you'd predict. Wish I'd understood that three dozen years ago.And the absolute worst black eye to the entire hang gliding group, which is actually quite the cool pastime ( I hold nothing gainst individual hang gliders doing their thing, looking after each other, taming the skies, etc.)...

Total BS. Time and resources ain't limitless, ya know. If you wanted to devote more time and resources to preparing and releasing you'd hafta diminish the time and resources you devote to suppression and misrepresentation.He blames it all on not having the time or resources to do it, which is total BS.

In my 1000+ tows, I've had to use my hook knife three times... the first was on a pulley tow when an old 2-string release didn't work. Sure did need that hook knife... and RIGHT NOW! Though it worked fine and I lost the bridle and release, it gave me the inspiration to come up with the Linknife.
...
Tad, you ignorant slut, if you read further than your selective snipping reaches to somehow prove a point, you would have read how this works. And, pray tell, what is the title of that page? Could it be "opinion"? as in a thought/idea. Surprising, isn't it, that I've heard from a couple of instructors (both with more credibility in their little fingers than you have in your self-inflated ego) who have been using similar systems for years to prevent hazardous scenarios from happening... and it works. But you'll never consider what actually works, just your own concepts of reality.

No. It should be reduced to a discussion of what's TYPICAL and how we need better efforts in risk management.The death of a loved one should not be reduced to a pissing contest.
The way Mission does things it's not safe for ANYONE.Ever. The fact is, there's a split amongst the hang gliding community over whether this is a "safe" activity for an H1 pilot or not.
There's a limit to how safe hang glider towing can be made. We CAN make it safer than the drives to or from the tow site but there's no fuckin' way u$hPa and its operatives will allow any movement in that direction. Can you imagine what would happen to their visibility as a liability target if Mission ordered a shipment of a few dozen Kaluzhin releases at this point?Hey, nothing in the air is safe. Or, rather, it's as safe as we are willing to make for ourselves and for each other.
'Cause from that point on she'd have needed BOTH hands to fly the glider.The "story" is that Nancy may have turned away from the line without disconnecting, which directly led to her being killed.
...useless, stupid, dangerous but...Well, this is not the entire truth. A more likely and accurate story goes like this: Nancy was a student who aspired to hang glide. She had taken many lessons and gone through all the preliminary trainings through at least 2 or 3...
...and least......different instructional groups, the last...
If she actually did she'd have never allowed herself to be put into that situation....of which was Mission Soaring Center. She gained her H1 rating, and was so proud. She was having so much fun. And she also knew the risks...
Then she got what she paid for, had a fantastic experience on her last flight, and did the gene pool a favor....that actually added to the fun (as it does for many of you.)
Two more than I've ever seen in any Mission video.From what I've been told, and seen in videos, there are two safety releases in a tow.
Probably thought she could fix a bad thing and didn't wanna start over.One of them is operated by the pilot.
What the fuck do you mean by a "SAFETY release"? Is this sailplane dude:Should that safety release...

operating his SAFETY release? As opposed to what other kind of release? If somebody runs a red as you're starting through an intersection do you step of your SAFETY brakes? A release is part of a glider's control system. We know what it's supposed to do and we don't need a redundant adjective connected to it.
According to whom? Has anybody ever done any simulations to provide the slightest evidence that this is fail safe? Or did some total fucking asshole(s)......fail, then there is a backup which is supposed to be a fail safe.

The thin 1500 pound aerotow bridle
...just declare them the to be fail safe?Davis Straub - 2005/05/03
Bob Lane said that Quest Air sold over 40 of their bridles (and Bob sold 15 or 20) during the Nationals. The Quest Air bridles use thicker Spectra and are designed not to whip around and accidentally tie themselves to the carabineer. Bob says his bridles will not do this either.
It is great to see these safer, simpler, and easy to use aerotow bridles becoming popular.
Sound familiar...Neither of these releases functioned on Nancy's fourth flight on April 3rd, 2016. They had not been thoroughly checked, just presumed to be working.

...people of varying ages?
The same instructor who outfitted him with the easily reachable two-string release and fail safe Birrenator backup?That's the job not only of the pilot, but also, more importantly, the job of the instructor, who is the last line of protection for his students.
How can it fail if it was never designed to work in the first place?He failed. He allowed the equipment to fail.
Pat - is our understanding.And believe me, he...
He must. Why else would he have spent these past months in total lockdown mode?...feels badly about it I have no doubt.
None of whom have come ever to Kite Strings to get understandings of the incident and/or done anyhing to reduce the likelihood of this happening to somebody else.I feel tons worse. And so does Nancy's mother. So do Nancy's siblings. So do the multitudes of her friends who still cry wondering why she is no longer with us.
Yes...The instructional group, Mission Soaring Center used faulty, unchecked equipment, and ended up killing a perfectly talented and well-taught pilot.

Well taught.
Big fuckin' surprise.And now they and the USHPA continue to cover it up. Witnesses who were actually there, and there were at least 4 or 5 who saw what happened, have remained mum (or have been instructed to not say anything) about the whole incident.
It should trouble you, as it does me, that a community of hang gliders, that are supposed to have some kind of integrity and care about each other in the air...
...when push comes to shove...
And viciously attack anyone who bring it back to the forefront in an effort to have it actually addressed....they disappear and hope a painful tragedy like this just "goes away."
There are PLENTY of more than deserving motherfuckers in this sport. If Jim Keen-Intellect Rooney had bought it in place of Zack Marzec on 2013/02/02 I'd still be barely able to contain my joy.I wouldn't wish this kind of tragedy on anyone else.
Yeah. Hang gliding people will now suddenly start developing character and decency.But I do hope that the community pulls together and talks about this, aims the sharp finger of responsibility (and blame), and fixes the problem: 1) Using unchecked, faulty equipment, and 2) an overprotective, biased, ultimately useless home-brewed fake organization like USHPA will bring more bitter tears.
Wouldn't start holding my breath just now if I were you.More tragedies. More blemishes and bruises to what could still turn out to be a noble and fun pastime if people own up to their mistakes and truly try to protect those who need protecting.

Yeah, just 'cause after four and a half months we've gotten no acknowledgement from Mission, u$hPa that there'd been an incident of any kind doesn't mean there's been no investigation.Can you provide any evidence that this is the case?First and foremost, there has been zero investigation.
1. The way Doug Hildreth did all the time over the fourteen year course of his tenure as Accident Review Committee Chairman.Can you provide any evidence that this is the case? I have known Mitch for years and spoke extensively with him regarding safety and reporting requirements. He is the USHPA safety officer and he is responsible for doing investigations. For legal reasons they are extremely strict. He cannot discuss cases specifically.Mitch Shipley has proven slow, resistant, and ultimately useless. He's had over 30 days, well over 30 days (which is by far a reasonable amount of time) to complete an investigation. Yet he refuses to do so. He blames it all on not having the time or resources to do it, which is total BS.

Suck my dick, Davis.Can you provide any evidence that this is the case? I do not find this obvious at all.That's pretty obvious code for the fact that he's covering up some pattern of mistakes on the part of Mission Soaring Center. And USHPA is also protecting the manufacturers of the safety equipment which failed Nancy when she most needed it.
http://ozreport.com/forum/viewtopic.php?t=31052I have no evidence that USHPA protects manufacturers and have never seen it. I have no idea who built whatever equipment it is that you are referring to.

You know, after all this discussion I'm now convinced that it is a very good idea to treat the weaklink as a release, that that is exactly what we do when we have a weaklink on one side of a pro tow bridle. That that is exactly what has happened to me in a number of situations and that the whole business about a weaklink only for the glider not breaking isn't really the case nor a good idea for hang gliding.
I'm happy to have a relatively weak weaklink, and have never had a serious problem with the Greenspot 130, just an inconvenience now and then.
Sure it does. What other reason would you have for forcing everyone to fly with the shoddy crap you sell at the competitions you run?No, it does not add to the fun.And she also knew the risks, that actually added to the fun (as it does for many of you.)

A hundred miles south of useless.It is neither over protective, biased nor useless.
Yeah, Ziggy. Everything's fine. Just listen to the sociopath and ignore everything you're actually seeing.I do not know that interactions that you have had with the USHPA, but I would suggest that you have drawn the wrong conclusions.
Blindingly obviously naked emperor.ziggyc - 2016/08/19 00:28:55 UTC
Absolutely there's evidence, or lack thereof. When we call the Hollister law enforcement and they have no idea there was any death at Tres Pinos, no case number, no nothing about a tragic event which is in their jurisdiction, then it's clear that something fishy is going on. So no, there has been no investigation. NONE. Mitch claims to be investigating, but he is not a credible individual, nor is USHPA a credible "organization."
I have approached several witnesses online (nicely, mind you) and received no response. That tells me someone (Mitch) got to them first and hushed them up. That's not very professional at all, if as you claim, they can talk to anyone. Cleary they can't, and are compelled not to speak out.
Mitch informs me that USHPA is a non-profit group which works using only volunteers. That screams out rag-tag and amateur. So yes, USHPA is a fake unprofessional organization that pretends to do one thing, but whose apparent goal is to obfuscate and cover-up the truth about any tragedy, no matter how severe.
u$hPa doesn't tolerate real safety-conscious individuals doing anything.They have had plenty of time to complete their so-called investigation yet Mitch has done nothing. Not very trustworthy. Probably should resign and let a real safety-conscious person do the job.
Don't be.So, in response to your questions, I have done my homework over the past several months, and have compiled plenty of evidence to back up my claims that there is a major cover up going on, and who I think is responsible. Any rational, thinking individual with half a brain would draw exactly the same conclusions if they were in my shoes. Maybe even worse ones. I believe I'm being nice about it.
Not sustainable. Total implosion.But enough is enough. USHPA needs to make their investigation public. Oh, that's right,...they're afraid to publicize anything about their investigations. It might shine a light into that dark place and reveal them to be that sham organization.
...fake...ziggyc - 2016/08/19 00:40:14 UTC
I should add that we called authorities in Hollister, San Benito County, Monterey County. All the local law enforcement and even fire departments. The only info that any of these outfits had was that there was a paramedic dispatched. That they did not conduct an investigation. Also we have the Coroner's report from Monterey County And THEY even had the cause of death wrong. They listed her activity as paragliding, which is not quite accurate.
Also, I appreciate your...
...sympathy and am not intending to throw real heartfelt sympathy...
Davis defends them because he is them....back at you in a vindictive way. I do appreciate it.
I have read a lot, made a lot of phone calls, been in touch with all the major players that I am calling out. Actually received correspondence which I won't share online for obvious reasons. but I DO know what I'm talking about.
My accusations about the USHPA may seem irrational to someone who may be on the inside, or who has closer ties than I do. SO I will stand back and say that I am making accusations about USHPA. But I am making them based on my first-hand experience with them. Just as you defend them based on your first-hand experience.
Maybe we can hire an investigator to find out exactly what it is that the professional staff and office actually does.Davis Straub - 2016/08/19 01:00:46 UTC
The USHPA has a professional staff. And a professional office. It would appear that you have not investigated the USHPA enough to be aware of this.
But apparently too overwhelmed to actually report on any actual fatalities.Like many if not all amateur sports organizations, it has a volunteer BOD and relies on volunteers for many of its functions. Mitch is a volunteer.
Yeah, it would be a serious violation of US Constitutional laws if Mitch's investigations weren't secret.Mitch's investigations are secret and are required to be so for legal reasons.

Didn't you find those useful? The key to not being killed on a hang glider is to avoid suffering fatal injuries. Nancy obviously hadn't done her assigned reading very well.2015/08/23
Rafael Lavin (69), an Advanced (H4) pilot and USHPA member since 1993, suffered fatal injuries during a flight at Fort Funston in San Francisco, CA. The circumstances surrounding the incident are currently still under investigation.
2015/08/23
Craig Pirazzi (56), an Advanced (H4) pilot and USHPA member since 1986, suffered fatal injuries during a flight at Indian Creek near Moab, UT. The circumstances surrounding the incident are currently still under investigation.
Yeah, make sure you convey to Nancy's family how much worse off they'd be right now if it weren't for u$hPa.As good or bad as our organization is, only a moron would think we are better off without it.
Why would anyone batter the organization who DIDN'T have a working knowledge of its function and process?It would be great if some of the trolls that take sport in battering USHPA actually demonstrated a working knowledge of the function and process of this organization at any time during their rants.
Big fuckin' surprise.I will not attempt to do that here...
Great volunteers like Mitchell N. Shipley - working tirelessly to produce these valuable reports that nobody's ever permitted to see. (Ever hear u$hPa calling for more volunteers to assist Mitch in his "accident" "investigations"?)...but I will reiterate one point that has already been made; it is a volunteer organization.
What's not to like?If you don't like something...
That's what I do over here, you miserable little Establishment cocksucker....get involved and work toward the change that you believe is necessary.
And when you get used to sucking u$hPa dick the way Matt has you'll lose the desire to spew irrational, unsubstantiated, conspiracy babble there. You'll start sounding exactly like Davis - pseudo intellectual crap oozing with fake profundity and totally devoid of any actual substance.Caution though, as this will eat into troll time and reduce the amount of irrational, unsubstantiated, conspiracy babble that you will be able to spew here.
Why should there be any anti-USHPA renegades? Monopoly control of US hang gliding, decades of tireless work protecting itself from an hint of accountability... What's not to like?As far as the personal attacks that have been made against Mitch, you clearly got your feelings hurt and are responding in the most logical way, here on a public forum like a big boy....lol Anyone other than one of your fellow anti-USHPA renegades will see that blather for what it is.
Fuck your community.It's easy to sit on the sidelines and be critical. Get in the game, get educated and attempt to actually do something positive for our community and then your words will have some credibility.

Making sure student pilots are prepared properly? Is exactly the subject I am and have been referring to. Knowing how to control a hg wing is what prevents mistakes made by pilots. Putting new pilots on a high powered tow system with minimal launching and landing skills. Is always a recipe for disaster.
Right Ziggy. Whenever somebody fatally slams in it's entirely a consequence of him or her fucking up. Instructors, schools, tow operators, junk equipment pushers, u$hPa are always one hundred percent blameless. And if someone doesn't agree with those principles, then he or she doesn't need to be involved in our sport. So Nancy's good either way - she will no longer be involved in our sport no matter what.Ryan Voight - 2016/08/19 18:20:43 UTC
First and foremost- I am very, truly, deeply sorry for your loss. I have been around free flight for a long time, and have experienced the loss of people very near me. Logically, it always seems to come back to that they messed up... but that of course does not make it *ANY* easier to cope with, accept, or move forward without them.

All permitted in Jack's Living Room anyway.However- before talking about how to best move forward in a healthy, productive direction for all...
Yeah let's. We know Mission uses state-of-the-art equipment - which they won't describe on their website 'cause they don't want anyone else copying and using state of the art equipment - and from the posts and videos of their victims we know that they're using two-string "releases", which will not work under load, and Birrenators, which are known to kill people when they increase the safety of the towing operation during steep climbs and which obviously did nothing in the case of this fatal lockout....it does appear there are some conflicts in what you have said, which I'm quoting below, and adding underlines to the parts needing attention:
I quoted most of the paragraphs rather than just extracting the highlighted lines, to maintain context of your words.ziggyc - 2016/08/18 22:08:22 UTC
The pilot, Nancy Tachibana, who had an H1 rating and nearly 30 tows over the past few months, was well versed in the activity and the how and when to use the quick release. There are substantial videos that show she was not only comfortable doing this, but she new what to do, and when to do it.
...
The fact is, there's a split amongst the hang gliding community over whether this is a "safe" activity for an H1 pilot or not. Hey, nothing in the air is safe. Or, rather, it's as safe as we are willing to make for ourselves and for each other.
...
And she also knew the risks, that actually added to the fun (as it does for many of you.) From what I've been told, and seen in videos, there are two safety releases in a tow. One of them is operated by the pilot. Should that safety release fail, then there is a backup which is supposed to be a fail safe. Neither of these releases functioned on Nancy's fourth flight on April 3rd, 2016. They had not been thoroughly checked, just presumed to be working. That's the job not only of the pilot, but also, more importantly, the job of the instructor, who is the last line of protection for his students. He failed. He allowed the equipment to fail.
In summary of what you said:
- She knew what she was doing and how to do it
- She knew safety was her responsibility
- She knew the risks and willingly accepted them
Then you posit that the release(s) failed because they went unchecked. I have no information regarding this accident, so I will abstain from any speculation whether this is true or not... or if the accident was even related to a hardware malfunction in the tow release. Since your conclusion was drawn from these statements- let's assume they are accurate...
OK, let's change it to "he succeeded".Your concluding statement "he failed"- referring to the instructor- that really seems to jump beyond what your statements support.
1. It's a fuckin' Hang One STUDENT. Hang Ones are supposed to fly UNDER SUPERVISION.If we're accepting what you said about the release not functioning, and the cause being failure to check it, please recognize that this is first and foremost the responsibility of the pilot to check and test.

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.

...actually WORKS?Paul Tjaden - 2008/07/22 04:32:22 UTC
I have never had a lockout situation happen so quickly and dramatically and had no chance to release as I have always thought I could do.
Goddam right about that...By your own statements, this pilot knew this, as well as what the consequences could be of failing to satisfy the responsibility to maintain her own safety. I agree that in the learning environment a large part of an instructor's responsibility is to provide double-duty in these responsibilities.
Your conclusion that "he failed" is not false; but it is highly incomplete. SHE failed, too. And I find it pretty hard to place blame on one individual's failure when the other individual committed the *exact same failure* for themselves (the individual with the most to lose, and greatest incentive not to fail).
Mission's still training students on the same state-of-the-art equipment at their dedicated training site at Tres Pinos, nobody got penalized two percent of a parking ticket. Meanwhile Brad Geary gets his tandem ticket permanently revoked for:The Mission Soaring Hang Gliding school provides professional training on state-of-the-art equipment at our dedicated training site at Tres Pinos (near Hollister, CA),.. just south of the San Jose / San Francisco Bay Area.

'cause of u$hPa's zero tolerance stance on safety issues.
I'd go for manslaughter in a New York minute. And don't think for a nanosecond that the thought wasn't crossing Pat's mind as he was watching his student's fatal plummet. (Kelly Harrison solved a lot of u$hPa's problems by being killed along with his victim.)You are accusing a group of humans of killing another human. Did you intend to throw a murder/manslaughter accusation out there?ziggyc - 2016/08/18 22:08:22 UTC
The instructional group, Mission Soaring Center used faulty, unchecked equipment, and ended up killing a perfectly talented and well-taught pilot.
Same way Quest killed its last two victims - both Fours and professional pilots.How could they have possibly killed a "perfectly talented and well-taught pilot", unless she messed up and didn't check her own release?
NOT a fucking Hang ONE.And if she did forget- couldn't you actually say she killed HERSELF?!
Let's do Arys while we're at it - the pilot u$hPa refers to as:(I do apologize, and realize how hard that will be for you to hear/realize/accept). But blaming others for the pilot's own oversight of their responsibilities is pretty hard for the rest of us to hear, too...
...his 11 year old student...
Nothing. Nothing to talk about either. 'Cept for...If the pilot messed up, and her death resulted... what is there to cover up?And now they and the USHPA continue to cover it up. Witnesses who were actually there, and there were at least 4 or 5 who saw what happened, have remained mum (or have been instructed to not say anything) about the whole incident.
...why no accident report has been PRODUCED to totally absolve Mission of any responsibility for this one and emphasize what a sterling job they continue to do in the safety department.Mark G. Forbes - 2016/04/06 16:41:47 UTC
There was a fatal crash on Sunday at the training site in Tres Pinos, near Hollister. The H1-rated pilot apparently turned away from the line, locked out and failed to release. An investigation is under way to review the facts and produce an accident report.
How 'bout in aerotowing, Ryan?And... what is there left to talk about??? Going only off of the information YOU have provided, and granting the assumption it is all entirely accurate, you know what caused the fatal accident. You know who could have, should have, caught it before she launched. You know that she was well aware and accepting of that responsibility, too.
You ended your post on this note- and so I'll do the same:
Some may regard it as semantics, but there is a difference between fault and blame. While the fault in this tragedy may be shared, ultimately the responsibility of keeping the pilot safe, falls wholly on the pilot.I wouldn't wish this kind of tragedy on anyone else. But I do hope that the community pulls together and talks about this, aims the sharp finger of responsibility (and blame), and fixes the problem

How come the Pilot In Command of an aero tow is NEVER held the least bit accountable for the one or two passengers who die behind him?Jim Rooney - 2013/02/16 05:05:41 UTC
Ok, keyboard in hand.
I've got a bit of time, but I'm not going to write a dissertation... so either choose to try to understand what I'm saying, or (as is most often the case) don't.
I don't care.
Here's a little bit of bitter reality that ya'll get to understand straight off. I won't be sugar coating it, sorry.
You see, I'm on the other end of that rope.
I want neither a dead pilot on my hands or one trying to kill me.
And yes. It is my call. PERIOD.
On tow, I am the PIC.
Now, that cuts hard against every fiber of every HG pilot on the planet and I get that.
Absolutely no HG pilot likes hearing it. Not me, not no one. BUT... sorry, that's the way it is.
Accept it and move on.
Not only can you not change it, it's the law... in the very literal sense.
OK, I'll make it for him.If you were making accusations that she was poorly trained, or not made away of her responsibilities, this may (perhaps) be a different conversation.
A One is - BY DEFINITION - a poorly trained pilot. And it's fuckin' ABSURD to be TOWING someone who hasn't been qualified to do more than fly a glider straight into a light breeze to three hundred feet.The United States Hang Gliding and Paragliding Association, Inc. - 2016/05/11
Standard Operating Procedure
12. Rating System
02. Pilot Proficiency System
06. Beginner Hang Gliding Rating (H1)
-C. Recommended Operating Limitations for Beginner Pilots flying solo:
01. Should exceed these limitations only after demonstrating complete mastery of the required Beginner tasks (above), and only after acquiring a full understanding of the potential problems and dangerous situations which may arise from exceeding these limitations.
02. It is highly recommended that all flights be made under the direct supervision of a USHPA Certified Basic or Advanced Instructor.
03. Should fly only in winds of 12 mph or less, with gust differential of 5 mph or less.
04. Should foot launch only on slopes of 3:1 to 6:1, where wind is within 15° of being straight up the slope.
05. Should launch only when there are no obstructions within 60° to either side of intended flight path, and when pilot may fly straight out from launch to landing with no need to maneuver and no possibility of over-flying the landing area.
06. Should maintain flight heading within 15° of directly into the wind.
07. Should fly appropriate sites so as to maintain altitude below 100' AGL.
Yep.But you state loud and clear how educated and competent she was. You want to place blame- look no further than human error. It is tough to blame the loss of a human life on the mere fact that they were human... but that is what YOU are saying with the information provided.
I was totally cool with Rafi. Been putting out the stomp test message for years, taking all manner of stupid flak and abuse for it, he couldn't be bothered.The very last thing you say is about fixing the problem. We do not agree on what that problem is. The problem I see, is that those of us left in the wake of great tragedy, are compelled to search for understanding of why and how this could happen. We feel pain, and anger, over our loss... and putting the responsibility of making us feel this way unto the deceased is grotesquely unthinkable (believe me, I get it, truly!).
Yeah. Litigation didn't exist back in the Doug Hildreth days when we we're getting lotsa good, honest, detailed reports.And so- a world is created where information regarding even the simplest of errors often does not flow freely, for fear of litigation.
People who haven't crawled out from under their rocks to utter any words to discredit anything Ziggy's saying.Just here you have accused people of murder/mansaughter, albeit not in those words.
'Specially incompetent negligent motherfuckers who have really excellent reasons to be scared shitless over this one.Is it entirely unreasonable that might frighten people away from sharing with you?
Ain't that a bitch.We have a problem, here in the U.S.- where people can sign a waiver acknowledging and accepting risks, and yet still turn around and file a lawsuit.
Maybe the motherfuckers who run these shoddy operations and put people up on total shit equipment, pissing all over the individuals who've worked their asses off...Regardless of how likely to win that suit may be, it requires legal defense, and that is freaking expensive.

Tad Eareckson or Heath Robinson?
Sure it was, Ryan. Just another one of those shit happens things. If Mission got a do-over they'd do it exactly the same as before because they're totally state-of-the-art - easily reachable releases, Birrenators, no guillotines. Still no guillotine - 'cause amending one now would be an acknowledgement that Nancy would've been OK if they'd had one before.And in this case, the party that signed that acknowledgement and acceptance has tragically passed, and so now we are left with a loved one looking for who to blame... and that anger spills over toward USHPA, toward Mitch as the ACCIDENT investigator (it was an ACCIDENT!).
No. The conversation was coming along just fine and things were continuing to evolve for the better before this asshole came along and gave us the last name of the victim.So- how do we fix the problems of having to be so reserved with talking about these things? I'll propose- don't go around saying so-and-so group KILLED her... and talking about the sharp finger of blame and it's need to point somewhere anywhere other than the person who has already paid the ultimate price for their mistake...
Get fucked.Respectfully,
Ryan Voight
