Would this work?

- Fuck no. The shit doesn't work. If it did, we'd be using it everywhere. But it doesn't stand the test of reality.

- Shit, Brian. You forced me to kill the better part of a day pulling stills from that one. Seventeen of the fifty-one:

Yosoytupadre - 2016/05/26 22:20:36 UTC

What's needed is training and clear thinking so that pilots who begin to PIO get off tow before they have a true problem. IMHO

Davis was too polite. Require a vertical tail? F* that. Get off tow.

Davis, the decision to get pilots who loose their weak links or who release early back to the front of the tow line is a good one. It encourages pilots to make safe decisions. It shoudl be clearly and repeatedly emphasized at the races.
Fuck you, the horse you rode in on, at least seven generations of your ancestors, and any descendants you have or may have until your DNA contribution is diluted down to at least 0.1 percent.

But also fuck fins and their advocates.
NMERider - 2016/05/26 22:42:09 UTC
Davis Straub - 2016/05/26 21:44:55 UTC

So the two other lockout fatalities recently are ground tow incidents as I guessed. Not sure how the mouth release applies to them.
What part about lockout and hands-free release wasn't clear?
Clarity is to Davis what garlic is to regular vampires.
Blown hand transitions are by far the leading cause of landing crashes.
Taking hands off of basetubes, going upright, and attempting foot landings is pretty much the only cause of landing crashes, injuries, deaths.
Why? Because the glider is not at trim. While under tow and in any stage of a lockout the glider is extremely far from trim and on many levels. Releasing your grasp and reaching for a release only exacerbates the out-of trim condition geometrically and further worsens the lockout situation.
To put it mildly.
It's all about not having to release either hand and for a number of different reasons too. Anyone who wishes to avoid being caught in a lockout needs to have some form of hands free release.
- The only way to be certain to avoid lockouts is to fly in smooth air. Read sled conditions. If you wanna maximize them fly in thermal conditions pro toad - preferably behind a tug driver who makes hard low level turns.

- Fuck hands free releases. This:

http://c1.staticflickr.com/3/2938/13700558193_0e0946218e_o.png
Image

...is the best and safest aerotow release on the market. It allows the pilot to blow tow by sliding his hand several inches inboard while maintaining back-pressure on the bar. Ideally no hand movement would be required but I defy anybody to cite a lockout crash in which that release would have been problematic.

For all practical purposes hands free releases are bite controlled and one point. And one point decertifies the glider / introduces a substantial danger that is in no fuckin' way offset by a better but less comfortable actuation mode.

It's decidedly more awkward but we need to stop talking about hands-free releases and start talking about both-hands-on-the-basetube-at-all-times-releases.

Ah! Here's a thought...

P.S. Not really sure how to pronounce "Peghiny" at this point but in this medium it doesn't matter.

Tragedy at 2016 Quest Air Open
Steve Morris - 2016/05/26 22:44:27 UTC

To all who think pilot skill is all that's needed to tow safely consider this recent event described by a world class pilot:

http://westcoastbrit.blogspot.com/2013/05/a-couple-of-weeks-ago-i-had-experience.html
earth turns and wind burns: Lock out on tow

Read it closely and note:
1) Failed attempt to release (by hand) while wrestling with the dynamics of the glider in the lockout.
2) Glider sideslips dramatically for 4 seconds (lack of yaw stability at a critical moment.)
3) Life saved by quick action from tow pilot who released instead.
4) Glider recovers very close to ground
5) All of this happens within 100 ft AGL at start of tow.

Top pilot, near fatality. How would the technologies being discussed here have changed this situation? I believe there is much room for improvement from existing technologies.

He's not a world class pilot. He's a dumb glider jock dickhead flying a totally illegal configuration deliberately designed by the Flight Park Mafia to be as dangerous as possible.
Read it closely and note:
1) Failed attempt to release (by hand) while wrestling with the dynamics of the glider in the lockout.
You read it closely. There was no failed attempt. He was making the easy reach to his bent pin crap facsimile of a release but his douchebag Dragonfly driver fixed whatever was going on back there by giving him the rope using his release which WASN'T within easy reach.
2) Glider sideslips dramatically for 4 seconds (lack of yaw stability at a critical moment.)
Bullshit. It was mega-stalled - a near fatal inconvenience.
3) Life saved by quick action from tow pilot who released instead.
Fuck Joel. He violated the crap outta FAA and u$hPa aerotowing regs and SOPs by towing a critically decertified glider with cheap total crap equipment.
4) Glider recovers very close to ground
5) All of this happens within 100 ft AGL at start of tow.
Lucked out.
Top pilot...
Bullshit. Brain dead dice roller.
...near fatality. How would the technologies being discussed here have changed this situation?
Hard to tell. Davis hasn't run any trial periods yet.
I believe there is much room for improvement from existing technologies.
And thanks for all the support for all my years of work this.
Davis Straub - 2016/05/26 22:53:31 UTC

Jonathan, perhaps you misunderstand me.
And with all of your efforts at clarity.
I'm asking what the configuration is that would be used for ground based towing that would incorporate a mouth release.
Why don't you ask Steve Exceptionally-Knowledgeable Wendt or Jim Keen-Intellect Rooney?
I also asked you earlier which of the three configurations that I presented for aerotowing with mouth releases you preferred.
And remember, Jonathan. You're only allowed to choose from the configurations that Davis presented.
No answer there.
Here's one... Go fuck yourself.

That's correct Steve. Image Image

The technology to prevent Ben Dunn's near-fatal lockout already existed and was available prior to his accident.

Hi Tad.

I'm Tracy Tillman, on the USHPA BOD, on the Tow Committe, and I am an Aviation Safety Counselor on the FAA Safety Team (FAAST) for the Detroit FSDO area. As a rep of both the USHPA and FAA, I would like to help you, USHPA, and the FAA improve safety in flying, towing, and hang gliding.

The FAA gets a lot of letters of complaint from a lot of yahoos...

Additionally, if you want to really present a convincing argument, you should also: (a) get other experts to co-sign your letter, such as those who have some or most of the aerotowing-related credentials listed above, who have been doing this for many years with many students, and who support your argument; and (b) present reliable data based on valid research showing that there is a significant difference in safety with the changes that you recommend. Supportive comments from aerotow experts along with convincing data can make a difference. Otherwise, it may seem as if your perception of "the sky is falling" may not be shared by most others who have a wealth of experience and who are deeply involved in aerotowing in the US...
The sport of hang gliding is and has always been adversely affected by its culture. The technology for safe flying has more or less been around since 1980.
Let's make it 1981 - although the theory dates back to 1979/09/26.
What hasn't been around is a culture of safety best practices and a culture that encourages and celebrates safety best practices or good risk management.
Got a culture that pisses all over it - and the Jack and Davis Shows are prime examples.
Whatever anyone wishes to call it. It is the sport's own culture that is killing pilots and not the lack of available technology, know-how, or off-the-shelf products.

Better mouse trap(release)?
Jim Rooney - 2010/12/16 18:47:05 UTC

Oh, I've heard the "everything we do is an experiment" line before.
The trouble is, it's not.

I've seen experimentation with towing gear more than anything else in HG.
I've not seen many go out and try to build their own sails for example. When someone does, they're very quickly "shown the light" by the community. Example... the guy that was building the PVC glider in California somewhere.
But for some reason, towing gear is exempt from this.

The difference is what we do has been done by thousands of people already. It's been tested... a lot.
What we do is free of the experimentation part.
It's still dangerous, but not at the level of building new gear is. Not even close.

That's what people fail to realize.
It's no small difference. It's a huge chasm.

Notice how I'm not saying to not do it.
Go forth and experiment. That's great... that's how we improve things.
I'm just warning you of that chasm.

A few years ago, I started refusing to tow people with home made gear.
I like the idea of improving gear, but the lack of appreciation for the world they were stepping into didn't sit with me.
For example... flying with the new gear in mid day conditions?
Are you kidding me????

Approach it for what it is... completely untested and very experimental gear which will likely fail in new and unforseen ways as it tries it's damndest to kill you... and then we can talk.
So is there ANY disagreement with the FACT that Bobby Fucking-Genius Bailey's cheap bent pin shit made that lockout unsurvivable? And how many of you cowardly cocksuckers stood up to that son of a bitch when a handful of us we're trying to get problems fixed? And can anybody quote Jeff Bohl making a contribution to a discussion?
So, thank you Ben Dunn for posting that valuable lesson. Image Image
And thank you Ben Dunn and Joel Froehlich for all the great follow-up work you've done on that near fatal and for your valuable contributions to discussions like these.
Davis Straub - 2016/05/26 22:58:12 UTC

Brian, that is a pro tow release combined with a mouth release for aerotowing.
Fuck you, Davis. It's hardware used for whatever anybody feels like using it for. And the Stage Two stuff is junk. But since there's close to zero chance of there ever being a situation in which it matters it'll be a cold day in hell before we see anything with any load capacity.
My question is really quite simple. What configuration of ground based towing bridle setup would you use and how would you incorporate a mouth release. I have only seen mouth releases used for aerotowing.
You're the one who's been dictating safety standards for your bloodbath comps since the beginning of time... Shouldn't WE be the ones seeking YOUR opinion?
Davis Straub - 2016/05/26 23:01:52 UTC

Yes, we repeatedly emphasized to pilots that they should release quickly if anything goes wrong as we would pick them up very quickly and get them back in fine.
Since repeatedly emphasizing to pilots that they should release quickly if anything goes wrong as they could otherwise be killed instantly wasn't having the desired effect. And yes, we also repeatedly emphasized to pilots that release quickly using the appropriate bent pin releases we mandated would in no way compromise their control authority for the brief period...
Dennis Pagen - 2005/01

By the time we gained about 60 feet I could no longer hold the glider centered--I was probably at a 20-degree bank--so I quickly released before the lockout to the side progressed. The glider instantly whipped to the side in a wingover maneuver.
...of their easy reach.
I put Fausto in line right in front of me after he had a weak link break., for example.
GODDAM! Betchya HE'll release quickly if anything goes wrong - knowing that you'll put him back in fine right in front of you. He'll be thinking, "If anything goes wrong I'll release quickly because Davis will put me back in fine right in front of him!"

You should go back to those more inconvenient weak links you used to use at Zapata...

http://ozreport.com/forum/viewtopic.php?t=24846
Is this a joke ?
Davis Straub - 2011/08/28 15:26:28 UTC

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.
Just think how quickly someone will release if anything goes wrong after getting to go back to the front of the line six times in a row!
We take the crew car pulling a cart and put a pretty girl at the wheel. She goes out as soon as the pilot lands and within less than a minute they are being pulled back to the line.
And all the guys who release quickly if anything goes wrong or have Rooney Link increases in the safety of the towing operation get to fuck her after reporting back in with their track logs.

And, of course, if anything goes wrong on tow the solution is ALWAYS to...

For all practical purposes hands free releases are bite controlled and one point.
What do you mean by practical purposes?

Tragedy at 2016 Quest Air Open
Davis Straub - 2016/05/26 23:05:49 UTC

The USHPA-sanctioned competitions have a culture of safety.
Fuck yeah! Right in line with the bottom item in u$hPa's mission statement:

http://www.ushpa.org/page/mission-and-history
Mission and History
Mission Statement

F. Safety. USHPA will steadily foster a culture of safety.
The u$hPa that no insurance company on the planet will cover at any price. Just foster a culture of safety then you won't have to do shit to make anything actually safe. Did you have extra FOCUSED PILOT wristbands on hands to equip pilots who'd inadvertently left theirs at home?
We have a risk mitigation plan for the Quest Air Open. You can find it here:
http://ozreport.com/docs/Quest%20Air%20Open%20Risk%20mitigation%20plan.docx
Great, Davis! We can look at everything pertaining to getting gliders airborne, analyze it, and see if we can put it into one of the two categories available to us:
- totally useless at best
- lethal
Risk Mitigation Plan for the Quest Air Open

1. Personnel

Meet Director - Belinda Boulter

Safety Director - Belinda Boulter, in consultation with Russell Brown

Towing Director - Russell Brown

Launch Director - Spencer Kindt, highly experienced Quest Air Manager and tandem instructor. Previous experience launching pilots at two Quest Air meets in 2015.

Launch Line Coordinator - Kate Griffin. Highly experienced launch coordinator at Quest Air and Whitewater, Wisconsin.

Launch Area Assistant - Dolores Mordesani

Launch Line Assistants - Yvonne Sargent, Michelle Haag, Dolores Mordesani

Weather Forecasting and Task Committee Leader - Larry Bunner, highly experienced competition pilot with many years' experience of local weather conditions. Previous experience in this role at two Big Spring meets and last year's Quest Air meet.

Zac Majors and Jonny Durand, number 3 and number 1 in the world will fill out the task committee.

2. Pilot Qualifications

Pilots must have the following minimum certifications or their national equivalent: Hang 3, RLF, Aerotow.

Pilots must have aerotowed with the glider that he/she is flying or similar at least ten times. Practice tows will be available onsite during the days leading up to the competition.

Both the Meet Director and the Towing Director have the power to exclude from the competition pilots who demonstrate a lack of the necessary skills for safe launching, flight or landing, or who lack the fitness to fly safely due to injury, drugs or medication that might affect the pilot's performance in the air.

It is the responsibility of every pilot to fly in such a way that personal safety and the safety of others is maintained at all times. Directors may penalize competitors who fail to observe this rule, or exclude them from the results.

Pilots are required to follow instructions given to them by meet officials expeditiously or risk penalty. Pilots will be instructed where to set up their gliders in the staging lines, where to enter the launch lines, and how to be prepared to launch safely. Pilots need to follow these instructions carefully.

3. Safety Committee

A Safety Committee of three competitors will be named at the first pilot briefing. The Committee will assess each task for safety aspects including weather, airspace and potential hazards after the task is first determined by the task committee. The task can be disapproved at that point and would have to go back to the task committee for revision.

The Safety Committee will determine maximum wind speeds (or speeds depending on direction) for the competition in conjunction with the Safety Director.

The Safety Committee will meet with the Safety Director on launch just before launch opening for a final assessment of the conditions and safety aspects of the task.

4. Weather forecasting, task planning.

The weather forecaster will be a member of the Task Committee. He will discuss at each Committee meeting any anticipated potentially hazardous conditions for that day. The Task Committee will take these conditions into consideration in the setting of each task.

Goal fields will be designated and assessed in advance by organizers.

In planning each day's task, the Task Committee will use such tools as SeeYou and Google Earth to assess such potential hazards as airspace, bodies of water, forested areas and other topographic features. They will take pilot safety into consideration in planning every task, and tasks will be reviewed by the Safety Committee as described above.

5. Safety briefing

A Safety Briefing will be included in the first Pilot Briefing, using the Risk Assessment outlines in the USHPA Sanctioning Manual, and including weak links, bridles, launching and towing issues.

Subsequent daily Pilot Briefings will include specific safety issues for that day, such as weather conditions, controlled airspace, potential obstructions and dangers along the route and at goal. Risks reported by pilots and meet staff, and any risky behavior observed will also be discussed.

The Weather Forecaster will discuss any potential safety issues as part of that day's weather presentation.

The Weather Forecaster and Task Committee cannot predict every circumstance that a pilot may encounter during the task. It is ultimately the pilot's responsibility to observe conditions and fly in a safe manner, or to land if necessary.

6. Equipment safety check in advance

All gliders and associated equipment shall be of sufficient performance and standard of airworthiness to meet the demands of international championships, and shall be flown within the airworthiness limits established by the manufacturer. Pilots are responsible for proper setup and pre-flight checking of all equipment.

Helmets and parachutes are mandatory.

Pilots will be encouraged to fly with radios, and a list of pilot radio frequencies will be maintained by the Meet Director.

Russell Brown will be in charge of pre-checking all the tugs. He will "green tag tugs" for flight operations each day, and "red tag" any not ready.

Quest Air staff will pre-check launch carts: grease the wheels, check tires for air pressure, check cradles, check keel height adjuster clips and have extra clips. Carts will be set to the right height for pilots. Carts will be kept in good condition and with proper tire pressure during the competition; an air pressure tank will be available at the cart setup area.

All tow ropes will be pre-checked, and extra ropes will be on hand. Proper carabineers will be used on the tow planes, with extras available.

Appropriate pilot weak links will be made up in advance. Pilots must use weak links provided by the meet organizers and in a manner approved by the meet organizers. All weak links will be checked on launch, and use of inappropriate weak links will require the pilot to go to the end of the launch line to change the weak link.

Weak links should be placed at one end of a shoulder bridle. The tow forces on the weak link will be roughly divided in half by this placement. Pilots will be shown how to tie the weak link so that it more likely breaks at its rating breaking strength.

Competitors must use appropriate aerotow bridles as determined by the Meet Director and Safety Director and their designated officials. Bridles must include secondary releases (as determined by the Safety Director). Bridles must be able to be connected to the tow line within two seconds. The only appropriate bridles can be found here:
http://OzReport.com/9.039#0
ProTow
Image
and:
http://ozreport.com/9.041#2
More Protows
Image
Image

Pilots with inappropriate bridles may purchase appropriate bridles from the meet organizer.

Does this mean no bike-handle releases, even for Sport Class? Nope.

7. Launch placement.

Each morning the launch area will be determined by the Towing Director based on the weather forecast, and will be announced at the Pilot Briefing. The launch placement will be confirmed or changed one hour before launch time.

Pilots must have all their gear and gliders in the launch area, away from the takeoff and landing areas, half an hour before launch open.

The Meet Director can suspend launch at any time for any safety issue. The Meet Director/ Launch Director can stop any pilot from launching who does not appear capable of launching safely. Launch will be suspended if there is an incident/accident in Quest Air field.

8. Launch procedures.

Both the Meet Director and the Towing Director have the power to ban flying from the site if a task or day is cancelled due to dangerous conditions.

Flags and/or streamers will be set out on the launch area, with larger wind indicators mid-field.

This competition will use an ordered launch, with numbered staging lines and launching in numeric order. There will be a "launch box" for the pilot preparing to launch next. There is no pushing (there is an implied push with an ordered launch). Pilots will not have to stay in their gear getting too hot because they will know when it is their turn to launch. The Task Committee may choose to offer an "earlybird" launch if that is deemed safe and desirable. Numbered launch and staging lines will keep pilots from tussling for position and help keep tempers cool.

Launch lines will be directed away from tug traffic. There will be a designated landing area and setup for tugs. There will be a designated landing area for hang gliders away from tug landing area and out of the tug setup area.

Launch crew will assist pilots in moving from the staging line to the launch line, with cart height adjustments, and with any last-minute equipment issues. The Launch Director will provide a final hang check for every pilot. He will wave off the tug only when he deems that conditions are safe and clear of any air traffic.

9. Monitoring conditions during an ongoing task

The Meet Director will monitor weather radar during launch and task.

The Meet Director will maintain a list of pilot radio frequencies and driver mobile numbers, to allow for rapid stopping of a task if necessary.

All pilots have the responsibility to monitor the flying conditions and should report to the Meet Director directly or through their drivers when conditions become unsafe on course. The Meet Director may cancel a task before any competitor has taken off if the weather becomes unsuitable or for safety reasons, or may choose to suspend the launch. She will attempt to consult with Safety Committee members by radio during the task, and may stop a task if the weather becomes dangerous. If the task is stopped it will be announced on pilot radio frequencies and to the drivers by telephone.

10. Pilots report on landing

Pilots will be required to report that they have landed safely by SMS to the Meet Director, who will record their status. At a pre-announced time (around Civil Twilight) the Meet Director will begin calling pilots/drivers who have not reported back, and she may decide to contact emergency authorities. Emergency authorities in the area will have been contacted by the organizers in advance, to make them aware of the event and pre-plan any emergency procedures.

Landing forms allowing for safety comments will be available at check-in, and at the pilot briefing the following day. The Landing Verification Form will contain the following and may be completed by each pilot as follows:
- 1. Safe
- 2. Unsafe in some parts
- 3. Unsafe. The results will be taken under advisement and may be discussed at the next Pilot Briefing.

11. Cloud flying

All competitors are required to comply with FAR 103 (U.S. Airspace Law/ Federal Aviation Administration Air Traffic Rule violations) at all times. A copy of FAR 103 can be provided to all competitors. Any verified infraction will result in a penalty (see below) for the associated day or possible ejection from the contest. Pilots are expected to familiarize themselves with all controlled airspaces in the vicinity of course lines (maps will be provided).

It is illegal and un-sportsmanlike for competitors to fly into clouds. Competitors who fly into clouds will incur a penalty for the day. A competitor is deemed to have flown into a cloud if he/she is observed by a meet official or videotaped going into and disappearing into a cloud, or videotaped appearing out of a cloud, or: If two witnesses from two different countries near the accused witness the accused going up into the cloud and completely disappearing from their view, and attest to this fact in writing and if barograph or 3D GPS traces from the accused and a witness show the accused above the witness at the time of the incident.

If the accused cannot produce a barograph trace for that day or a 3D GPS track log from their 3D GPS, only two witness statements are required. It is highly recommended for all competitors to fly with a recording barograph and they must fly with a 3D GPS at all times.

A pilot sucked into cloud who did not have the intention of gaining an advantage should perform a figure 8 maneuver once out of the cloud so that other pilots could see it had not been intended. It is recommended that a pilot sucked into cloud who did not have the intention of gaining an advantage should perform a figure 8 maneuver once out of the cloud so that other pilots could see it had not been intended.

Witnesses should press Mark/Enter when they witness a pilot going into a cloud. Any pilot found to be deliberately supplying false information about another pilot with respect to cloud flying will be removed from the competition.

The penalty - the offending pilot shall receive a 10% reduction in their score for the first infraction, 30% reduction for a second, and then a zero daily score for any further infractions.

Meet officials may fly with the pilots to check for cloud flying and to be in contact with the safety director (who will not be flying at any time) to report safety conditions on course. If the meet director is flying and checking on pilots and the weather the deputy meet director shall take over his duties.
Risk Mitigation.
Why ELIMINATE risks when you can just MITIGATE them?

Personnel.
Shoot Spencer Kindt, Kate Griffin, Yvonne Sargent, Michelle Haag, Larry Bunner, Zac Majors, Jonny Durand. Shoot Belinda Boulter, Russell Brown, Dolores Mordesani twice.

Pilot Qualifications.
Professional major airline pilot with decades of experience with a major carrier good enough?

Safety Committee.
Even worse than the Safety Committee on 2014/06/02 at the second to last ever ECC. Identify them and shoot them for the first time if not already covered above or an additional time if they have.

Weather forecasting, task planning.
Forecaster saw EXACTLY what it was doing during the beginning at the last attempt at a task and continued launching gliders anyway until one of them was killed.

Safety briefing.
Needs its name changed to something more appropriate.

Equipment safety check in advance.
How many more people does your safety equipment need to kill before you do something different to get different results?

Launch placement.
Probably best to suspend launch at some reasonable time BEFORE somebody gets killed rather than immediately after, dontchya think?

Launch procedures.
Would a glider locking out at thirty feet and slamming in a couple seconds later be some indication of dangerous conditions?

Pilots report on landing
What if the pilot is in a state of cardiac arrest after landing? Can the requirement be waived?

Monitoring conditions during an ongoing task
See above.

Cloud flying
No relevant problems there, fer sure.
Again, it was ten years ago that I highlighted the mouth release for aerotowing and repeatedly tried to purchase one without success.

Can't release the tow line
Aleksey Vilkov - 2015/08/03 06:17:16 UTC

Statik line towing with two stage release.
You can see here two ordinary releases. The first one is Russian Mouth Release (RMR), the second one is barrel type release made with webbing and short peace of pipe.
So, pilot is taking off with RMR and after reaching about 150-200 meters he is connecting second release with the bridle below speedbar to the ring in the end of line using ordinary carabiner. Of course he is immediately releasing RMR and continuing towing with barrel release.

Mouth release means "pro-tow" (1 point), not the safiest way to be aerotowed..
but as "pro-tow" devices, the followings are by far much better than the barrel bent pin and suitable for emergencies on the cart and in the air close to the ground. You won't use them very often but more than your chute for sure.

3 kinds of mouth release:

- The Russian

Image

Actuation: open mouth
no bridle. You need a ring and a weaklink on the towline.
more complicated to store after release (wire)
Easily useable by foot launching (but better to avoid it)
http://www.e1.ru/fun/photo/view_album.php?id=32439

- Tad's Remote barrel release

Image

Simple barrel release (NO bent pin !) on the other side.
Direct Load/Actuation effort #20
Used with a bridle.

- "Squidlinks Emergency Release"
http://ozreport.com/docs/squidlinks.htm
Tad re-designed it in a 4-strings, but use it at 3 strings offers better release at lowest load.
Image

Direct Load/Actuation effort : HIGH
You can use it already "armed" and just open your mouth to release
or with the lanyard through a clamcleat: pull first, then open mouth
The weaklink is a "bridle link" between the mouth release and the barrel release on the other side.

The latter two are not available in the market. Some did them but you can build your own.
Personaly, I use the remote barrel release with a 450lb weaklink. Works well.
What were/are your reasons for ignoring the other options Antoine documented in this post in response to the previous Quest Air negligent homicide?

Why can't the mouth element of that release be moved to the control bar, such that one index finger is holding it? The finger could be lifted or slid sideways to release.
Great idea, W9GFO! Sounds like a great project for you. Do keep us posted on your progress.
Davis Straub - 2016/05/26 23:07:55 UTC

Again, the mouth release is not "available" in the US. I have tried repeatedly to purchase one to trial it. No luck.
And subsequently no luck for Jeff Bohl neither. Bummer.

Fuckin' Russians have been using these mechanisms since the beginning of time with zero issue and for decade after decade the collective intelligence of the US / Canadian / Australian hang gliding establishment is totally incapable of coming up with anything better than a bent parachute pin with a length of nylon webbing looped through its eye stuffed in a fat little stub of aluminum tubing with a loop of some flavor of magic fishing line on the other end of the bridle in case of emergency - courtesy Bobby Fucking-Genius Bailey.

Totally incapable of importing them, using the plans they hand us...

Image

...to build them or have them built by a competent machinist... Can anybody name a another engineering based segment of our culture this fucking helpless and incompetent? It's like Western hang gliding is in an arms race to devolve from Predator drones with Hellfire missiles remotely operated from the other side of the planet to sharp sticks - 'cept worse.
Perhaps this time it will work as others make the effort.
There's a thought, Davis. Since you yourself have proven for decades to be totally incapable of accomplishing anything of any actual substance why don't you just evaporate from the sport entirely and give others shots at moving things in desirable directions?

Another thought...

This push for these release mechanisms is an admission that the crap you put into the air for the comp was inadequate for the job and dangerous. And it cost one of the competitors his life. If you were unable to run the comp with safe equipment why did you run it at all?

There's no fucking way in hell I'd have taken responsibility for that kinda bullshit. I'd have advised everybody to stand down and when they wouldn't I'd have reported them to the FAA for aerotowing in violation of the terms under which hang gliding was given its exemption to aerotow.

I, in fact, did that the better part of seven years ago and I don't have a single drop of blood on my hands or any problems with my conscience. Course you and your sleazebag buddies - having nothing in the way of consciences...
Davis Straub - 2016/05/26 23:09:54 UTC

Lookout makes and sells a release that is on the base bar. Unfortunately, it is only for two/three point bridle setup.
- OH! We seem to be acknowledging for the SECOND time in recorded history that a bridle setup that splits the tow tension between the pilot and glider might be a TWO point.

- But if you read the sucker's manual Lockout provides you after you've made the purchase you find that it's not warranted as suitable for towing ANYTHING and, on top of that, is not to be used with anything heavier than a Marzec Link. And if you read the traffic on the forums you find that it's a total piece o' crap that fails left and right.

Granted, the motherfucker has more than doubled the length of the lever arm...

Report about fatal accident at Quest Air Hang Gliding
Davis Straub - 2013/02/12 20:01:14 UTC

There is very little danger of pulling in too far on the pro tow release. And on the 3 point releases the problem is not that the pilot pulls in too far, but rather that the glider is pulled down as the carabineer rises up the V-bridle.
...because when the pilot pulls in too far the carabineer rises up the V-bridle and you get a tuck and structural failure under negative load. Another name for the V-bridle is positive feedback loop bridle. That's why you need to teach people to pro tow as soon as your schedule allows so they have the skill to fly the safer equipment.

- Unfortunately...
-- Under the Quest Air Open Risk Mitigation Plan it was an "inappropriate bridle" and could not be flown.
-- It is only for two/three point bridle setup. There's no fucking way that release could be implemented for a one/two point bridle setup.

Davis Straub - 2016/05/26 22:58:12 UTC

Brian, that is a pro tow release combined with a mouth release for aerotowing. My question is really quite simple. What configuration of ground based towing bridle setup would you use and how would you incorporate a mouth release. I have only seen mouth releases used for aerotowing.
Davis,

I had no clear idea of where three configurations fit into a discussion of hands-free release options. I say let pilots or instructors chose whatever configuration best suits the task.
Sorry Jonathan. That approach is simply not compatible with a Quest Air Open Risk Mitigation Plan. In a Quest Air Open Risk Mitigation Plan it needs to be dictated what's "APPROPRIATE" and mandatory and "INAPPROPRIATE" and banned. Otherwise what's the point in having a Quest Air Open Risk Mitigation Plan? Helmets, parachutes... Use whatever the fuck you feel like.
I don't see why a hands-free release can't be used in any or all of them. The only winch towing I have ever done was using the same pro tow setup I use for aero towing.
Please don't call that crap a "pro tow setup". Bear in mind that it just killed an airline pilot.
I have not had the chance to use a two-stage release for surface towing and I don't know how a mouth-release or other hands-free release fits into two-stage surface towing chest releases.

pro tow set-up
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 Image
Jim Rooney - 2009/11/03 06:16:56 UTC

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$$.
...actually MATTERS.
And the same would hold true for a keel bridle as I don't imagine a keel bridle exacerbating a lockout situation nearly as badly as the chest bridle would.
Oh. So you seem to be of the opinion that two point is inherently SAFER than pro toad - regardless of whether or not you've been at an around all this plenty long enough to understand what's what and who's who.
And so again, my best guess is that the hands-free release would activate the chest bridle rather that the keel bridle.
Let's throw out any discussion of two point towing for surface - other than for a sustained skim in scooter tow training. A keel attachment is making the transition from being of some advantage to totally irrelevant with every foot of gained altitude. Not worth it. I don't think anyone can cite a surface tow incident which would've been mitigated by two point.
As far as vertical fins are concerned I don't see how that even factors in to a discussion about where to connect a hands-free release.
Factors in bigtime - as far as sabotaging efforts to make actual positive changes are concerned anyway.
So that's my 2p worth at this juncture.

In the future please present the choices you wish address in the very same post where it's mentioned so it's readily apparent to readers.

Why can't the mouth element of that release be moved to the control bar, such that one index finger is holding it? The finger could be lifted or slid sideways to release.
There's no reason that it can't but the whole point of a hands-free release is that it makes no difference where the pilots' hands are in order to activate the release.
The whole point to a hands-free release - with is a synonym for bite-controlled release - is that the blindingly obvious and head-and-shoulders superior engineering solution is to have the release lanyard or actuator in one's teeth. There's minimal relative movement between the tow attachment points and the lanyard/actuator termination point and there's nothing else important in which that part of your body is engaged.
Until you've been trashed so badly that your hands become otherwise useless this may not make sense but hands can be extremely busy doing other things than patiently standing by a control bar mounted release.
The biggie is not having to totally let go of the basetube and go groping around for some moronic Bobby Fucking-Genius Bailey actuator within easy reach on a downtube or at a shoulder.

Pro towing: 1 barrel release + weak link or 2 barrel release
Ryan Voight - 2012/10/18 04:52:52 UTC

I use one barrel and two weak links. Protow both sides of the release are pretty easily reachable with either hand, IMO.
Also, always have a hook knife within quick reach, either hand Image

I guess the hook knife is my second release? Or is that third release, with the weaklink being a second? Whatever...

I also use old weaklinks. I have heard a lot of people say they want stronger ones... personally, I'd rather it break sooner than later... and if it does break, sooner OR later, it's my fault. If I can control the glider and keep it in place, I shouldn't pop weaklinks... even old ones...

I was using several-year-old weaklinks at SCRF, no trouble... usually they get so old that one breaks about every 3 years. No biggie.

I also don't tow very often... so they might be old but they don't get used a ton...
Pure unadulterated bullshit. And you'll notice that neither Ryan Instant-Hands-Free-Release Voight nor Jim Keen-Intellect Rooney has thought this one important enough for a single syllable's worth of comment.
There is no substitute for having available a hands-free release.
Yes there is.

A lot of work went into that configuration. That's the blindingly obvious and head-and-shoulders superior engineering solution for two point 'cause the release mechanism is ALSO mounted on the frame and thus there's even more minimal relative movement between the release and the lanyard/actuator termination point.

We'd rather not hafta have something in our teeth if there's no significant advantage in doing so. And the one point / secondary releases that both Steve Kinsley and I have developed are engineered such that we can spit the trigger line / actuator out once we clear the kill zone. The basetube actuator is where we want our hand anyway and there's no downside to be loaded for bear the whole trip up.

And if Jeff had been flying two point with its slightly more bothersome actuation system I have little doubt that he'd have been able to follow the tug and not have the need for a release - hands-free or whatever.

Yeah, let's rewind the tape, send him up with a two point bridle and no release other than a sheathed hook knife. My call is he doesn't get scratched. Let's do it. Nuthin' to lose on this one.
Notice that I did not say 'mouth release'. The operand word is hands-free. There may be other options. I don't know.
There aren't. Everything that could be done has been already. Everything has been available - and getting ignored and pissed all over for years. The foot actuated ideas are bullshit.

Mark G. Forbes - 2012/12/20 06:21:33 UTC

We're re-working the accident reporting system, but again it's a matter of getting the reports submitted and having a volunteer willing to do the detail work necessary to get them posted. There are also numerous legal issues associated with accident reports, which we're still wrestling with. It's a trade-off between informing our members so they can avoid those kinds of accidents in the future, and exposing ourselves to even more lawsuits by giving plaintiff's attorneys more ammunition to shoot at us.

Imagine a report that concludes, "If we'd had a procedure "x" in place, then it would have probably prevented this accident. And we're going to put that procedure in place at the next BOD meeting." Good info, and what we want to be able to convey. But what comes out at trial is, "Ladies and Gentlemen of the Jury, my client suffered injury because USHPA knew or should have known that a safety procedure was not in place, and was therefore negligent and at fault." We're constantly walking this line between full disclosure and handing out nooses at the hangmen's convention.
The Industry does NOT want these things to fly - for very obvious and openly stated reasons.

I don't agree that the important part is being "hands free". I think what is important is not needing to remove your hand from the control bar to activate a release.
Ex fuckin' zactly. What's important is keeping your hand in control position and being able to hold the bar back.
NMERider - 2016/05/26 23:53:35 UTC

If your release hand is in the wrong place during a lockout there is a good chance that the instant you release your hand or even just your grip in order to go for the release you will soon find your hand even further from the release and the lockout will become significantly worse.

...your chances of a crash - minor, serious, fatal - go through the fuckin' ceiling. But guess what one hundred percent of u$hPa instructors force their students to do in order to be able to land "safely".

2. Releasing your hand? Yeah. Big fuckin' deal. Jeff obviously understood that during the final few seconds of his flying career. And you might wanna tell Davis to go fuck himself when he's implying that Jeff's problem was that he didn't release his hand SOON ENOUGH and having a bullshit Quest Air Open Risk Mitigation Plan based on rewarding pilots who release their hands and themselves soon enough in a lockout with a trip back to the head of the line.

Even just your grip in order to GO FOR the release? Show me the release that necessitates releasing your grip but not your hand in order to blow tow.

You don't really need a GRIP on the control bar to make the glider...

...do what you want it to. Most of the time you just need a bit of push or pull. And in a lockout you can bank on it being pull.
If you don't believe me feel free to try it for yourself and see. Be sure you have at least 1,000' AGL before you attempt to find out.
Jeff would've probably been OK with a couple hundred. And that was pretty extreme.
Better to have a few K AGL and a fresh repack too. Image
I've put at least a hundred times more quality work into AT releases than any other human ever has or ever will. I'm not gonna tow one point in soaring conditions and there's no way in hell I'm gonna put a two point release actuator in my teeth. It's a miniscule advantage over what I have and what I have is overkill. The limiting factor with what I have is gonna be human reaction time.

In the case at hand it's a total no brainer that he'd have been fine with one of Joe Street's releases even if it had been used in a one point configuration.

Don't go nuts pushing hands free. Hands free means bite controlled/actuated, bite controlled/actuated has minor downsides and if the advantage is only miniscule people won't use them. Steve Kinsley flew a bite controlled one point and I flew a bite controlled secondary. And both of us would toss the option after clearing the kill zone.

Another point that needs to be made...

The release system I built into my glider kicks the shit outta anything else you're ever gonna see - which, of course, is why it gets studiously ignored and pissed all over by The Industry and its hordes of pet cocksuckers. Likewise all modern automobiles have astounding braking systems and capabilities. Anybody who puts himself into a situation in which more than a quarter of those capabilities is NEEDED is a fuckin' MORON.

I drive in a manner such my use of the brakes is gentle and minimal. When I drive through high deer likelihood situations I slow way the fuck down. When we hear somebody using one hundred percent of his braking capability two assumptions are pretty safe.
- We're gonna be hearing a violent crash in another fraction of a second.
- The person using a hundred percent of his braking capability is a major asshole.

Ditto for release systems. Pick an incident from the entire history of modern hang gliding - the past three and a half decades - to show me where a bite controlled release would've yielded a better outcome than a hand-slide release. This scenario is totally fictional. It doesn't exist in the real world.

The motherfuckers running that bullshit at Quest on 2016/05/21 should all be stood up in front of a wall. They were running a takeoff pattern with a very thin safety margin with gliders with blatantly illegal placebo releases. With ANY release that didn't totally stink on ice what they were doing would've been totally acceptable. They would've been able to afford putting a few gliders into lockout mode 'cause aborting the tows would've been brain dead easy. The risk would've been the same as for a normal glider landing approach. But as they actually WERE operating any glider unable to hold that turn was already dead.

You didn't NEED the best release engineering could produce and money could buy. You needed ANY release that would allow the pilot to continuously operate as a pilot with both of his hands in constant contact with the control bar.
Andrew Vanis - 2016/05/27 00:00:51 UTC

The Basic Handbook of Tow Launched Hang Gliding

"The greatest dangers are a rope break or a premature release."- Richard Johnson
If the pilot screams? BULLSHIT. PILOTS don't SCREAM. When somebody at the controls of a plane screams it's for one of two reasons. He's about to eat it because he's:
- not a pilot and doesn't know what the fuck he's doing
- in a situation in which being a pilot is no longer of any use or relevance and he's got nothing better to do

Show me a video of somebody who knows something about glider control screaming. I've got a collection of hundreds of classic glider disaster videos and I don't recall one of them in which the guy about to get his life majorly altered for the worse saying so much as "Oh shit!" let alone screaming. Jeff didn't scream or say anything immediately before or after his New and Improved Quest Link increased the safety of the towing operation.

Check this one out from fuckin' idiot Bill Bryden on another in our long list of pilots too stupid to make the easy reach to his release at the beginning of his fatal lockout:
Bill Bryden - 1998/12

Unfortunately, we suffered a fatal towing accident earlier this year but only recently received some details about it. Richard Graham, and advanced pilot with 24 years of experience, was fatally injured in a towing accident on May 15, 1998 near Grover, Colorado.

Rich was platform-launch towing in strong (25-30 mph) winds crossing 35-40 degrees to the tow road. Thermal activity was also reported as moderately strong. The launch sequence commenced with the "go to cruise" command, and the glider cleared the tow vehicle. Approximately 300-400 feet of line unspooled, and according to the data memory in the vario the glider reached about 80-90 feet AGL. The pilot then radioed to the vehicle driver to stop, and a few seconds later the VOX on his radio transmitted the words, "Oh no." The glider impacted in a steep nose-down attitude and then inverted.

It is suspected that no attempt was made by Rich to release since the towline was still attached after impact, and the release and winch were determined to be functioning properly before and after the accident. The event was not witnessed directly so it is unknown precisely what happened. It is suspected that the very strong and crossing conditions were a primary factor in this accident.
No scream, no "Oh SHIT!", just "Oh no." with the realization that his effort at a recreational flight would be costing him his life in a couple seconds and there wasn't a goddam thing he could do to alter what was about to happen.
W9GFO - 2016/05/27 00:01:35 UTC

What I was describing required no movement of the hand, no releasing of grip to activate the release. Instead of the clothespin thing in your mouth, it is between the bar and your forefinger.
1. What's stopping you from obtaining a Kaluzhin and using it in that configuration?
2. So it's pretty fuckin' obvious you're talking about one point. So apparently there's no danger worth talking about related to towing one point.

Hands move around during tow.
Not mine.

Image

Never once had the slightest inclination to move either hand an inch from proper flying position from the beginning of the cart roll to workable lift, wave-off, or lockout - whichever came first.
When all hell breaks loose the release hand may not be near enough to the release lever to activate in time to avoid crashing.
1. You're only in any danger of crashing for the first couple hundred feet. If you can't commit to having your hands in proper control position for the first couple hundred feet then find another hobby.

2. Having all hell break loose shortly after the beginning of an aerotow launch doesn't bode all that well for survival. Ditto for any other kind of launch.

3. In the case at hand:

- Jeff commenced, flew, and finished the flight with his release hand glued to control position - undoubtedly because he wasn't sure that Davis would honor his promise to move him back up to the front of the line for a relight if he released early.

- All hell breaking loose was a consequence of the tug making an aggressive starboard turn thirty feet off the deck.
Now there may be reliable alternatives to a mouth release that are hands-free.
There aren't any.
It's not something I've researched.
It's something I have. There aren't any.
Alternately there may be a way to attach a type of release directly to the pilot's hand so that no matter where the hand is, the release can still be activated.
Please describe all the great other places the pilot's hand needs to be when launching and climbing through the kill zone. Video examples would be greatly appreciated.
So I suggest imagining or making drawings or building mock-ups of ideas for some type of device that is attached to the hand in some way that would allow immediate release no matter where the hand is or what it's doing.
1. And make sure not to use any PVC tubing in any mock-ups...

W9GFO - 2016/05/27 00:18:41 UTC

I'm obviously not being very clear. You move your hand, and the tow is over - just like the mouth release, when you relax your jaw - it releases.

It's more of this crappy argument that being on tow is somehow safer than being off tow.

Is that a real thing? I don't recall ever not being able to keep my hand position, even when being thrashed about.

isn't it crazy that out liability laws and resulting fears prevent one of us making a small production run of the mouth releases?
Didn't stop me, motherfucker. It DID, however, get me blacklisted out of the sport - while total useless motherfuckers such as yourself lifted not a finger in protest and let the reign of terror of Davis Dead-On Straub, Jim Keen-Intellect Rooney, and Ryan Instant-Hands-Free-Release Voight continue unabated.
i wonder if a corp that would close after the delivery of the releases might provide enough protection
Get your shift key fixed. Also... Get fucked.
I might consider creating these if each order came with a notarized statement from the buyer that was hand written in front of the notary that says the buyer won't sue and if he does then he covers my attorney fees no matter the outcome plus in advance deposit $100K into escrow to cover said attorney fees even if he wins and if he wins he assigns the proceeds back to me and if his heirs sue (in addition to all the same purchaser stuff), they forfeit any share they have in the estate of the buyer.
Get fucked. What we SHOULD be doing is everything possible to help Jeff's family, estate sue out of existence ten times over everyone who had so much as a finger in the circumstances which had him up in that lockout with that cheap bent pin shit and the Quest Air Open Risk Mitigation Plan to keep him safe.

During a tow?
Of course during a tow. People get their hands ripped off of basebars all the fuckin' time during tows.
And if so, would you want to remain on tow?
Of course not. Remaining on tow at any time is totally insane. Why else would we have used one-size-fits-all Rooney Links for two decades and benefitted from all those inconvenience crashes when we could've been climbing out to workable altitude?

...many powered sporting craft like snowmobiles and jet skis. At least they did when I was a kid. Yes, the Russian Mouth Release is in fact a dead man's switch and if the pilot tended to clench his jaw when in fear then it really would be a dead man's switch but of a different sort.
'Cept that never happens 'cause actual pilots who actually equip themselves with actual towing equipment aren't ever faced with having to make the choice between dying because they:
- didn't make the easy reach to their Industry Standard release
- did make the easy reach to their Industry Standard release
Sure. why not! I don't see why a reliable dead man's grip device can't be fabricated so that all the pilot has to do is relax his grip or such (sort of like opening his mouth with the RMR) and the release is activated. I like the idea and don't see why the cable housing can't be routed along the pilot's arm for cleanliness too. I like it! Image Image
Great, Jonathan! How 'bout fabricating something for us? Or get Paul Hurless to post a sketch.

if that happened on tow, I'd probably be toast already and not writing here.
Why? You DO always us an appropriate weak link with a finished length of 1.5 inches or less, don't you?
It is about before-the-fact prevention than after it happens.
Like Davis's Quest Air Open Risk Mitigation Plan.
Hope you aerotow many a times without it ever happening to you and if it does, come back to report how it turned out for you.
Anybody ever heard of anybody ever having a hand ripped off the basetube in any kind of tow ever?
It is close to saying, since most tows don't have to be released in an emergency, we don't care how cumbersome or slow it is to release.

gasdive,

One of the stated goals of this site is to promote HG. MOST views on this site are NOT from members but from visitors, they have no ignore button.

Having Tad run around every day giving the impression that there is a massive weekly slaughter of pilots at tow parks due to their horribly dangerous devices surely doesnt promote HG. Especially when the safety records are quite excellent.

Like Jim said, theyve gone a decade with no fatalities at their tow park. Pretty damn good I say.

Yet listening to Tad, you would think guys were dying all over the place
He's been nothing but misleading and negative and ignored multiple warnings from me. So He's GONE
W9GFO - 2016/05/27 00:46:06 UTC

For the record, I am saying exactly the opposite. It is of the highest importance that releasing is as easy and quick as possible.
Rubbish. It's of the highest importance that pilots know that they'll go to the head of the launch line if they release in a lockout. That way they'll be less inclined to stay on tow attempting to correct a misaligned tow.

Tom Lyon - 2016/05/27 04:55:16 UTC

Where I fly at Cloud 9 in Michigan, every pilot flying a double surface glider is required to fly with a vertical stabilizer/fin. While I certainly understand that high performance gliders can be towed well without a fin, I do wonder if a fin might help delay lockout just a bit longer so that the pilot can release.

Assuming there isn't a medical condition that incapacitates a pilot before an accident like this tragedy, the most likely explanation is that the pilot either didn't think he was near lockout, or it just happened so fast that he didn't have time to react. It seems to me that a fin would at least help slow down the progression of lockout.

I don't suppose that comp pilots would be very amenable to discussing the idea of requiring a fin (assuming that there is agreement that they make a glider more stable on tow), but I don't ever plan to fly without one when I move up from my Falcon.
Fuck you and where you fly at Cloud 9 in Michigan, JackieB. Fuck everybody who tolerates total shitheads like you and lying Industry scumbags like Tracy and Lisa. And note the conspicuous absence of any comment by the latter on yet another one of these.

Good job Davis. I've tried a couple of times over the last year to get one from Russia, but with no luck.
GOOD job? TOTALLY FUCKING *AMAZING* JOB!!!
I really like the idea of being able to get off the tow, without moving hands at all.
I'll bet Jeff Bohl would have, too. Unfortunately for him, under the rules of Quavis's Quest Air Open Risk Mitigation Plan the idea of being get off the tow, without moving the hands at all, no implementation of the idea of being get off the tow, without moving the hands at all was possible. What they had in its place was the idea that a port lockout induced at thirty feet by a Dragonfly making an aggressive starboard turn would be survivable flying the cheap pro toad bent pin shit that Quavis sells and mandates.
Cheers.
Pete
Fuck you, Pete.

Everybody watching the dynamics here? Davis, more than any other single individual, sets up an airline pilot to be killed at one of his pecker measuring contests. And here on The Jack Show in less than half a dozen days later he's being praised for his outstanding leadership in our never-ending campaign to advance the safety of the sport. And ya wonder how the dangerous useless shits upon whom u$hPa bestows annual u$hPa NAA Safety Awards are designated to receive annual u$hPa NAA Safety Awards.

Brian, that is a pro tow release combined with a mouth release for aerotowing. My question is really quite simple. What configuration of ground based towing bridle setup would you use and how would you incorporate a mouth release. I have only seen mouth releases used for aerotowing.
Do you use a two stage for aerotowing?

Two stage mouth/barrel release
Davis Straub - 2015/08/12 20:58:54 UTC
Aleksey Vilkov - 2015/08/03 06:17:16 UTC

Statik line towing with two stage release.
You can see here two ordinary releases. The first one is Russian Mouth Release (RMR), the second one is barrel type release made with webbing and short peace of pipe.
So, pilot is taking off with RMR and after reaching about 150-200 meters he is connecting second release with the bridle below speedbar to the ring in the end of line using ordinary carabiner. Of course he is immediately releasing RMR and continuing towing with barrel release.

Aleksey Vilkov - 2015/08/10 08:55:38 UTC

You can see with more details on the attached video how the combination of the Russian Mouth Release and barrel release is working at two-stage towing.

Aleksey Vilkov - 2015/08/14 11:56:43 UTC

I would like to add that we are using RMR not only for aerotowing, but also for all kind of ground towing including platform and dolly launch.
Well, it's not like Davis Dead-On Straub actually reads any of the stuff that he writes and links to. He's obviously much too busy writing Quest Air Open Risk Mitigation Plans and deleting posts which give concrete information about the implementation and effectiveness of his Quest Air Open Risk Mitigation Plans.

Nasty AT Launch Cart Accident - Face Plant
NMERider - 2014/03/06 14:48:13 UTC

O.k. folks, Here's the full first-hand account of the accident:
Ollie Chitty

i do have a barrel style release but i have corred out a golf ball and that is what i use, its much easier just to "slap and release" rather than trying to find a defined small barrel!
...to make it POSSIBLE to pry open just prior to impact in an emergency situation. My call is that if he hadn't there'd have been no fuckin' way he'd have totally wasted his time on the attempt and he could well have ended up just as dead as Steve Elliot did from his pro toad dolly launch that wasn't compromised by a snagged wheel when separating from the cart.

And on that note...

With a gun to my head I'd say that Jeff would've been OK with a Koch two stage used as a one stage in his situation. Everybody's gonna risk half a second with a hand off the bar to take a slap at a paddle on the chest. NOBODY's gonna further compromise his situation by wasting his time trying to find and pull that bullshit little stub of aluminum tubing which can't be budged under significant tension anyway.

I'd LOVE to get my hands on Jeff's easily reachable Industry Standard release...

Barrel Release - Wide - Pin Destroyed

This Pin was deformed under something under a direct loading of 220 pounds (achievable for a 315 pound glider using a 1.4 G Weak Link).
That's just ten percent over what his was loaded to just before his Standard Quavis Link increased the safety of the towing operation.
