Steve...

Yeah, I was tired and didn't read / think about your post very carefully. Brain stopped working when I read the word "hit".

The original Hewett Bridle left with the bridle and first and second stage releases. You were supposed to twist your body to get your head out of the way before blowing the contraption. I kited up on a payout over Jockey's Ridge in strong wind - 1984/05/12 - and released under tension. Had forgotten about the twisting part. Got my helmet slammed stunningly hard by the panic snap...

...component on the keel. Only time I'd ever needed a helmet for anything other than protection from the wind, sun, cold.

Brian...

Something else that video shows really well.

At the beginning of the tow it's a two point one to one bridle. But the pilot leg is routed under the control bar, torques it up a little, negates some of what the keel attachment is accomplishing.

By the time it clears the control bar the tow angle is so steep that the keel attachment isn't helping much with trim.

As the climb approaches its max potential all the elements that are being tensioned and tensioned and weigted are so close to parallel that it makes it real obvious that we're now dealing with what's essentially a one point tow.

What a crappy way to run an airline.

And damn. Another video from which I'm gonna need to pull some stills.

In this video the spreader is much closer to the carabiner than the keel, allowing the hang loop to touch the keel. This raises some questions:

Could this interfere with the pilot's control authority?

Is the spreader fixed to the hang loop so it cannot be moved? This glider seems to be a Discus and drawings in the manual http://www.aeros.com.ua/manuals/DiscusV04.12.07.pdf pages 44 & 45 show the spreader in a low position.

If your hang loop is simply wrapped around the keel then a spreader in the hang loop wouldn't do much. I can't speak to details of non-WW gliders so they may have other reasons for using one. But probably not.
klh wrote:I looked at a Freedom 190 today and it had a kingpost hang and spreader bar in the hang loop. Spreader about 5" long.
Owner said it was the "race" package if that makes any difference.
Fly with the spreader up near the keel for best effect.

Makes me suspect they want to sell me a VG adaption kit, since I've got the spreader bar and no VG.

Failure to Hook In
Bob Kuczewski - 2019/12/08 20:04:47 UTC

Here's a sobering video about the "failure to hook in" issue:

http://www.youtube.com/watch?v=csDRdqMH3Kk


That video recently appeared on both Oz and hg.org:

Make sure what you hooked in to is attached correctly - Holy S*** this was a close one.

Here's the video by TheFjordflier (posted in 2015 by Brian 2 posts back):

Hook in ( last chance), version 3
http://vimeo.com/124963665


It's a great video, but do you see the problem? If TheFjordflier had hooked in with a "velcro only" connection, his video would NOT have ended nearly so happily.

There is nothing wrong with doing a "lift and tug" hook-in check while launching, and I encourage it when it doesn't add additional risk (as it might in certain launch situations). But the "lift and tug" has its own failure modes as seen in the improper "velcro only" connection video. That velcro connection was obviously strong enough to support the pilot's weight (at least for a little while) so it would have certainly passed the "lift and tug" test. That failure mode would likely have been fatal if it happened in TheFjordflier's video.

My point here is that any one check alone is insufficient. A good part of this topic was spent trying to stress the value of a thorough hang check (including an inspection of the connection point as in Joe Greblo's Four C's) along with a "just prior to launch" hook in check. They are BOTH needed. The velcro connection video is proof that a hook-in check alone (such as "lift and tug") just prior to launch isn't enough.

Aviation requires careful discipline. That's why there was a printed check list in every airplane I've ever flown. A careful hang check should be part of our check list and a hook in check immediately before launch should also be part of our check list. They do different things, and they are BOTH important.
Here's a sobering video about the "failure to hook in" issue:

And I'm happy you have The Bob Show available for you to express YOUR idiot rot for all to see - if they want.
Here's the video by TheFjordflier (posted in 2015 by Brian 2 posts back):


Hook in ( last chance), version 3

It's a great video, but do you see the problem?
Some of the spelling could use some work? Cut him some slack. English ain't his first language.
If TheFjordflier had hooked in with a "velcro only" connection, his video would NOT have ended nearly so happily.
Also if one of his sidewires were in the same shape one of Rafi Lavin's was at Funston on 2015/08/23. But what the fuck does that have to do with anything in Jan's video?
There is nothing wrong with doing a "lift and tug" hook-in check while launching...
Oh bullshit. Everyone and his dog knows that doing a "lift and tug" hook-in check serves only to give you a false sense of security. They cover that in all the u$hPa Instructor Certification Clinics and all Day One, Flight One students are advised that they'll be penalized with a three year ratings revocation if they're ever observed doing one and surviving.
...and I encourage it when it doesn't add additional risk (as it might in certain launch situations).
- Well I guess you've never been in a launch situation in which it doesn't add additional risk 'cause I've never seen a video or heard a report of you actually doing one.

- Bull fucking shit. We have references to lift and tug going back to 1977 and we don't have a shred of documentation of the slightest compromise of control let alone a skinned knee attributable.

- NOBODY does this in some certain conditions and not in other certain conditions. The people who get this do it 100.00 percent of their launches because they're ALWAYS scared shitless of launching unhooked. If you're not ALWAYS scared shitless of launching unhooked your chances of launching unhooked go through the ceiling.

- You also encourage people to tow with Rooney Links because of the glider's extremely mild response when one increases the safety of the towing operation when everything's going along fine.

- You're not an instructor, never were, never will be. You're a politician - you want to have as many people as possible liking and supporting you. When you're an instructor you're forced to take solid, up front, positions on procedures and equipment. And when you do that in this bullshit sport you're automatically gonna alienate a minimum of seventy percent of your potential base. And whenever you commit to anything solid you're gonna alienate 99 percent - if you're lucky.
But the "lift and tug" has its own failure modes as seen in the improper "velcro only" connection video.
- IMPROPER "velcro only" connection? The connection released at about 1.25 Gs and he was able to stay with the glider and control and land it fairly safely. If it had been a 2.0 G Tad-O-Loop there's no fuckin' way he'd have been able remain connected. It would've been certain near instant death. And you want him to use a STRONGER loop?

Hahahahahahahahaha. Oh that's just rich! HAHAHAHAHAHAHAAHAHA.

No, I'm not being nice. No, I do not feel the need to be nice. You're trying to convince people to be less safe. I've heard it a million times before from comp pilots insisting on flying with even doubled up velcro (some want NO velcro). I tell them the same thing I'm telling you... suck it up. I can live with your inconvenience.

Please tell me again what's wrong with the wheel? Why you keep trying to reinvent it?

Yes, please fall back on the "I'm just saying they could be stronger" bull when you've made it quite clear that anything lower than cable (1200lb) is acceptable.

The simple fact is that you're not improving the system. You're trying to make it more convenient and trying to convince yourself that you should be flying with stronger velcro. Enjoy your delusion.

- Bullshit. Lift and tug is used to verify that you're connected and have about the right clearance and your leg loops. It can't, isn't supposed or expected to verify that:
-- you're not partially or otherwise insecurely connected
-- a mouse hasn't converted a lot of your hang strap webbing into nesting material since the last time you packed up your glider
-- your keel isn't corroded
-- what you believe to be a headwind isn't a rotor produced by a tailwind
-- the asshole on your starboard sidewire won't pull your wing down and backwards when you call 'Clear!" and start your launch run.
That velcro connection was obviously strong enough to support the pilot's weight (at least for a little while) so it would have certainly passed the "lift and tug" test.
It's not a fucking TEST. It's a fucking CHECK. That's why it's called a hook-in CHECK. If you really wanna TEST it then take it up a couple thousand feet and pull six Gs. Otherwise set up and preflight your goddam wing like it tells you to in the fuckin' manual.
That failure mode would likely have been fatal if it happened in TheFjordflier's video.
But it didn't happen in Jan's video 'cause as you can very clearly see in the video he's not using a shitrigged suspension extension.

This was a KNOWN ISSUE. 1991/11/03 Leonard Rabbitz and 1997/04/04 Tom Sapienza - both fatal. This motherfucker injured himself pretty good. He could've done the job right with some webbing, dental floss, and a needle - like I did. Hell, he did pretty good with just the velcro for a fair bit.
My point here is that any one check alone is insufficient.
Wow Bob...

One last attempt.

We have now rounded up all the usual suspects and promised renewed vigilance, nine page checklists, hang checks every six feet, et cetera. Bob Gillisse redux.

A hang check is part of preflighting your equipment. You do it in the setup area - not on the launch or the ramp. When you get in line you are hooked in and ready to go. No going down for a hang check cum hook in check.

JBBenson - 2009/01/25 16:27:19 UTC

I get what Tad is saying, but it took some translation:
HANG CHECK is part of the preflight, to verify that all the harness lines etc. are straight.
HOOK-IN CHECK is to verify connection to the glider five seconds before takeoff.
They are separate actions, neither interchangeable nor meant to replace one another. They are not two ways to do the same thing.

I sure wish some of us other folk had the grasp of the issue that you do.
A good part of this topic was spent trying to stress the value of a thorough hang check...
Fuck thorough hang checks. You can't do a thorough hang check when you're doing a hang check 'cause you can't see and inspect anything that matters when you're hanging in your harness. Tell me ONE ISSUE - beyond clearance on a new configuration - that a hang check can identify that a standing visual can't way better.
...(including an inspection of the connection point as in Joe Greblo's Four C's)...
- I rest my case.
- Fuck Joe Greblo and his goddam Cs.
- Exactly what are Joe Greblo's Four (or Five) Cs, Bob? Nobody seems to know for sure. And Joe never seems to be able to clarify the issue for us.
...along with a "just prior to launch" hook in check.
This isn't an FTHI incident and it's not in the FTHI topic. I wasn't able to jump on this one right away but within ten seconds of seeing the video I'd decided that this one would be dealt with in this "suspension" topic. Steve picked up on it right away and posted where it should've been posted.

This guy should've been hooking one nonlocking carabiner into one loop and fuck the backup. Instead he had three. The aft was a no-brainer. For the fore there were two options and on this occasion he got the wrong one.
They are BOTH needed. The velcro connection video is proof that a hook-in check alone (such as "lift and tug") just prior to launch isn't enough.
- No shit, Bob. Quote a hook-in check advocate ever once saying or implying anything otherwise.

- The implication clearly being that Tad...
Zack C - 2011/12/17 14:56:03 UTC

There's really nothing I can say that Tad hasn't already said better, but in the interest of hearing it from someone else...

1. You continually misrepresent Tad's statements...
...was cluelessly ranting that it wasn't.
Aviation requires careful discipline.
And a weak link which will infallibly and automatically release the glider from tow whenever the tow line tension exceeds the limit for safe operation.
That's why there was a printed check list in every airplane I've ever flown.
Most of your guys are really hurting in the reading comprehension department so maybe you should try some other approach.
A careful hang check should be part of our check list...
Assuming you're flying your regular glider harness combo tell me one good reason for executing a hang check.
...and a hook in check immediately before launch should also be part of our check list.
If you need to consult a checklist before executing a hook-in check you have no business flying. And ditto for driving back home.
They do different things, and they are BOTH important.
- Hang checks are total bullshit. Only total idiots do them.

- D-Garck did a hook-in check as he launched (which is when about 99.9 percent of the hang gliding public do them) and a 56 second hang check in flight - both of which indicated everything was fine. What's the title of his video?

- This is Catch-22 total crap. If you:

-- preflight this glider you don't fly it 'cause it has shitrigged suspension. That's kingpost suspension (with the spreader up where it's supposed to be for something new and different) - Sport 2. So every time you effect roll input you abrade the primary and extension webbing. (And you also hafta use a little more muscle.)

-- shitrig this glider in this configuration you're not likely to catch this near fatal issue. Garck DOES preflight his suspension and misses the issue that almost kills him.

And after your support for Sam and in light of what shortly thereafter happened to Terry you don't get to advise anyone on safety/competency issues.

D-Garck - 2019/12/06

http://www.youtube.com/watch?v=csDRdqMH3Kk


This is a cautionary tale for fellow hangglider pilots.

I made a critical error during my setup which caused my harness to separate from my wing and forced me to hold on to the control frame for my life. Fortunate circumstances led to me surviving this incident with relatively minor injuries.

I was asked if I thought about landing in the ocean to possibly soften the landing. In the moment I had not thought of doing this, however I don't think that I would've decided to do so given my fast rate of decent, the low tide, and the fact that I risked not being able to swim while in my harness (although the risk of being trapped under my wing might have been significantly less considering I was no longer connected to it).

It's very fortunate that the hang loop let loose while I was facing into the wind. The wind this day was consistent at about 20 mph. The fact that my crash landing was going into the wind meant that my ground speed was significantly slowed (as compared to if my crash landing was going down wind).

Considering I used this hang loop setup for many flights in the mountains, this location is potentially the most fortunate place for such an incident to occur. I can't imagine having to hold on to the glider for much longer than I did. If this had occurred in the mountains, where the landing zone is much further away from the launch, I doubt that I would have had the strength to hang on for the duration of the flight out to the landing zone.

Please be very vigilant when preparing to fly to avoid such an incident as this one.

Fly safe my fellow pilots!
Boy we're lucky to have this astounding video. Too good to be true. I downloaded it almost immediately after it came to my attention - just in case. It's a one-of-a-kind and the quality is pretty damn good.

Most of these are fatal and u$hPa and/or other guilty parties are virtually always able get the card vaulted, swallowed, shredded before it can see the light of day. (I'd kill to get my hands on Jean Lake.)

The video is 1280x720 but there's some crap on the edges (an issue we haven't had much in recent years) and I had to cut four pixels off each side and three off the top and bottom - so 1272x714 (which makes no difference at 800 width display resolution). Note that he shot this at a higher frame rate than what we're seeing in the first sequence of the flight. In the slo-mo run there are frames that didn't exist before.

Interesting to note that discussion on the Jack (worlds largest hang gliding community), Davis, Bob (free speech utopia) Shows is virtually nonexistent compared to what's going on with the YouTube page. Lotsa big names; posts - even if incompetent - are extensive and substantive, Garck's participating. Everywhere else, clubs, Peter Show... Zilch. Excellent illustration of what tends to happen in the face of long term authoritarian repression. YouTube is the new hang gliding coffee shop.

Launch is real close to:
34°22'53.92" N 119°29'03.76" W

Suspension looks a bit short. Hope you'll be able to do something about that before moving up to launch. (Probably finished the exercise in about that position - a good bit worse for wear.) And note that the guy who's assisting Garck on this prep, carry, launch (and who was undoubtedly assisting in the recovery) hasn't participated in any discussions, doesn't identify himself, isn't identified.

Loses the glider 'cause these bozos station the assistant on the nose (to keep the glider from pitching up and over instead of on wing so's they can effortlessly and safely keep the glider under control. This one needs a topic sometime.

Great. But this is NOT when and where you should be realizing that a(nother} fairly critical element of your control system sucks.

This launch totally sucks.

- If you have a wire guy you put him on a wing where he can actually help you when you actually want need him to. The critical time is when you're initiating launch. This asshole is nowhere around when Garck's launching.

- The sidewires are slack 'cause he's at a neutral angle of attack. He should be standing upright with the wing flying at about trim or a bit lower.

- Then ya torque the nose down, power yourself and your wing down and forward until you have tons of airspeed, ease out, climb straight up until you can't anymore, roll hard to stay up and back in the optimal area of the lift band.

Note: Even after watching the video, knowing what happened and why, hearing the explanation, looking at this reconstruction model with the actual incident component it's damned difficult to see the problem. Average Joe Hang Glider Pilot ain't gonna catch it. Fatality waiting to happen. (Good way to kill someone and have it look like an accident - 'specially in a culture in which garden variety unhooked launches are pretty common and nobody sees any problems with easily reachable bent pin barrel releases and Infallible Standard Aerotow Weak Links.)

I highly recommend that anyone else using a similar setup modify their setup by either cutting off the velcro so this mistake can never happen, or installing a primary hang loop which is the correct length (to eliminate the need for an extension).

I plan to install a correct primary and a secondary safety loop as well.

After this hard landing I had severe pain in my right knee but no other major injuries.

MRI determined a complete tear in continuity of my posterior cruciate ligament (PCL) and sprains of my medial patellofemoral ligament and medial collateral ligament (MCL).

Thankfully there were no fractures and my minisci and other ligaments are intact.

I feel incredibly lucky to be alive.

I refuse to let this incident affect my attitude towards hanggliding. I plan to return to the skies as soon as I'm healed and strengthened.

Stay safe out there fellow pilots!

Diligently preflight your gear and minimize or eliminate any chances for human error or oversight.

The flight that almost killed me
John Heiney

That you were able to able to hold on in that situation is nothing short of stupendous. Glad you're still with us. Your continuing to make roll corrections to keep the wing level until the end is remarkable. You really kept your cool in a terrible situation.

Manufacturers decided some time ago to use an integral back-up strap, ostensibly for drag reduction. This idea completely ignores one of the two reasons for having a BU-strap. Reason #1. Main strap failure. Reason #2. Failure to hook in properly. If there is a separate BU, any sensible pilot will extend the BU too. One could conceivably hook in incorrectly to both, but a redundant BU at least doubles your chance of success.

The problem with the integral BU hang strap is that it looks like one hang strap. Newer pilots who are not familiar with the idea of a BU will extend the one strap when they really should use an additional BU extension, which would have saved the day in this case. I carry an extra-long hang loop in my harness with my extension loops, so I can add a separate BU when needed.

If manufacturers will revert back to the original logic of a separate BU strap, pilots' lives will be saved. No pilot flying for fun needs to reduce drag to this degree. Most pilots plow through the air head-up anyway making the idea of trying to hide the BU drag in the main ludicrous. Comp pilots will always trade safety for performance, but rec pilots should not be mislead into thinking we need this minuscule drag-reduction feature at the detriment of safety.

I know a guy who's main broke while he was looping. The separate BU saved him. I knew a guy who died because he didn't hook into his extension correctly around the time the first integral BUs were introduced. I'm sure that he would have extended the BU had there been a separate BU strap hanging there in front of his face while he was hooking in. That's why we need a separate BU.

The idea that hooking your harness into your glider before you climb in will prevent launching unhooked is a fallacy, because we humans are fallible. As long as there is a carabiner that can be unhooked, an unusual situation will arise when the pilot (a human being) will unhook and forget to hook back in. There is no foolproof way of preventing unhooked launches unless the harness does not detach from the glider.

The best way I have seen that reduces the likelihood of launching unhooked is "Marginal" Mark's method of lifting the glider until you feel the leg loops pull up on your legs, then launch in that condition. This also insures that you are in your leg loops. This method does take a fair amount of strength. If you are not strong enough to hold the glider up while you launch, you should at least do a quick lift to feel the leg loops tighten just before you go.
That you were able to able to hold on in that situation is nothing short of stupendous.
Bullshit. He supported his weight plus harness and parachute never pulling more than a bit over one G for fourteen seconds. Chris Gursky - Interlaken - 2018...

...held on for two and a half times that - minus the parachute but in a more demanding configuration. And he tore a tendon just from holding on and we don't hear from Garck that he was stressed in the least.
Glad you're still with us.
Maybe you should publicly comment on the incidents resulting in participants not being still with us.
Your continuing to make roll corrections to keep the wing level until the end is remarkable.
What a stupid comment.

- If you're making roll corrections the wing isn't staying and you're not keeping it level. And it doesn't start or stay anything close to level.

He steers it out for his second best landing option. (In the ocean with about four feet of water under him would've been better but that would've been a tough call to hafta make.)

...not thinking about what's going on with the horizon.

- NOTHING he does in this video is remarkable. The modification which precipitated this moderate disaster and near fatality was shoddy, his ground handling and launch management and execution were crap, and his ridge soaring performance left something to be desired.

- He lucks out in having the separation hit him at an optimal enough point and in optimal enough circumstances and conditions that he's able to remain connected to the glider. And your making a statement like this is pissing all over the individuals who've made the same mistake and haven't been able to stay with the glider - through no further fault of their own.

The only thing moderately remarkable about this is that he posted the video, has treated it as a proper incident report, is engaging in full and honest discussion. And that SHOULDN'T be remarkable and decades ago wouldn't have been but in contemporary hang gliding culture dregs like Joe Greblo, Sam Kellner, Paul Tjaden, Pat Denevan, Kevin Kader are the norm.

What's remarkable in this sport is seeing people flying with solid gliders and equipment; preflighting, hook-in checking, launching, approaching, landing properly; functioning as competent pilots. And when I look at and read your crap I don't see it.
You really kept your cool in a terrible situation.
Rubbish. He did what he had to do as a consequence of not having done what he'd needed to do and was keeping the cool the situation permitted him - as was Lenami. She held on up to the point at which Jon's shoes separated from his feet. Where's the praise for her keeping her cool on her first (and last) hang gliding experience ever? Cite an example of a flyer at any level in the sport not keeping his cool in an emergency situation. We all try to respond with what we know or believe to be the best inputs all the way to recovery, landing, or impact.

P.S. Any comment on the degree of cool Jim Keen-Intellect Rooney was keeping as he dove himself and his glider and passenger into the powerlines in front of Coronet Peak on 2006/02/21? Why is this one worth commenting on while that one wasn't?
Manufacturers decided some time ago to use an integral back-up strap, ostensibly for drag reduction.
- Yeah. It reduces drag. I'm all in for ANYTHING that reduces drag without compromising anything that matters.

- I have an even better way to reduce drag. Don't incorporate a stupid backup strap.

- Stupid manufacturers. Their gliders just keep getting crappier and crappier with each passing year. (Note that it was Wills Wing - with no help from John Heiney - who first debunked the Comet era "floating crossbar" bullshit and promptly and permanently eliminated the extended keel pocket and related crap from all their designs.)
This idea completely ignores one of the two reasons for having a BU-strap. Reason #1. Main strap failure.
Yeah, that's a biggie. About thirty incidents a season reported in the US alone. And virtually all of them due to issues nearly impossible to detect on preflight.
Reason #2. Failure to hook in properly.
Bull fucking shit. The backup loop was/is a total cave to glider people stupidity. PERIOD. It doesn't solve problems - it creates them.
If there is a separate BU, any sensible pilot will extend the BU too.
A sensible pilot will remove anything that smacks of a backup. (Took me about a quarter century to overcome my indoctrination and become sensible.)
One could conceivably hook in incorrectly to both, but a redundant BU at least doubles your chance of success.
Bull fucking shit. Anyone who's incapable of properly hooking into a hang loop, checking his connection, verifying that he's connected in under two to four seconds prior to launch needs to find another hobby. An actual sensible pilot will never have the slightest need of or desire for a backup loop.

That's not to say that you won't get the rare fuckup like this one and that Garck was/is fundamentally incompetent as a pilot - but you don't retool the whole system for one of these one-in-a-million fuckup events. (And I believe that guestimate to be reasonably close to reality. But if I were forced to revise I'd start multiplying the million end.) He shitrigged his glider for long term regular use with what he had on hand, didn't review the magazine archives to educate himself about this known fatal issue that his shitrigged instructor didn't advise him about, came damned close to buying the farm.

This is a fairly good parallel to the Infallible Standard Aerotow Weak Link. Everybody's gotta fly with one a hundred percent of the time 'cause they're will be the odd one in a million event in which some incompetent fuckup might have been / be saved by one. And screw any and all downsides for everybody else.
TheFjordflier

WOW! That was too close. You unknowingly stacked the odds in your favour, plus some quick reactions. Glad you survived. Another location...probably another outcome. And a couple of seconds extra, looking at your connection during preflight wouldn't have harmed ;-) Next time! Thanks for uploading the video. You will never ever do this glitch again, believe me :-) Nice flights.
Correct. He will NEVER make that mistake, or anything similar like a partial hook-in...

...again. He's been educated - fourteen seconds of terror and some substantial injuries.

But also nobody who's seen that video will ever make that mistake. Which means that this issue can be totally dealt with through classroom EDUCATION - which is what you're supposed to be getting when you pay for u$hPa instruction and pilot rating.

Willy Dydo, Fly Away Hang Gliding - damn good bet. And we're gonna assume that it was 'cause that motherfucker hasn't bothered to participate in this rather intense global discussion of this incident which occurred about fourteen crowflight miles ESE from his training site (Elings Park). Hasn't taught him:
- to execute a hook-in check just prior to launch
- how to:
-- ground handle with a wire guy
-- assign position for wire crew
-- execute a foot launch into soarable ridge lift conditions
-- perfect his flare timing (we can very safely assume)
- not to fly with shitrigged equipment

And, John, I notice you're not addressing any of these issues.
The problem with the integral BU hang strap is that it looks like one hang strap.
- Here's a thought... Eliminate anything along the lines of the idiot fucking BU hang strap.

- The current Wills Wing kingpost suspension configuration is two straps supported from a bit up the kingpost by tangs bolted to its sides. It essentially IS one strap. There's ZILCH difference between this and a single double thickness nylon strap - one that will hold two hundred times the capacity of the glider instead of just one hundred times the capacity of the glider. The only reason they do it this way is so they can tell their idiot dealers and customers that their glider has a backup strap.

Fairly clever strategy - I must admit. Although the proper, ethical, decent thing to do would be for them to announce that they are reverting to their original policy of not shipping with backup straps 'cause they don't do anything beyond adding expense, weight, and drag and introducing problems. And while they're at it... Issue an advisory to remove all backup straps from all relevant currently flying Wills Wing gliders.
Newer pilots who are not familiar with the idea of a BU...
- Are in for a real treat if they start looking into all the idiot bullshit that goes on in this idiot sport.

- How 'bout newer pilots who are not familiar with the idea of a carabiner locking mechanism?

? Yeah, it just fills my heart with unmitigated joy whenever I see pilots making solid efforts to do things right.
...which would have saved the day in this case.
Yeah, let's all equip our gliders with proper backup loops so we can safely shitrig our primaries.
I carry an extra-long hang loop in my harness with my extension loops, so I can add a separate BU when needed.
Tell us about some of the times you've needed a backup loop, John. You're gonna blow your fuckin' glider apart a few dozen Gs before you're ever gonna need a backup loop. Me? I just preflight my suspension every time I fly so I can know I won't need the stupid backup.
If manufacturers will revert back to the original logic of a separate BU strap...
- There was never the SLIGHTEST degree of logic associated with a backup loop of any kind.
Mike Meier - 2005/08/~18

It shouldn't matter whether the backup is in front or behind, because it should be longer than the main such that it is always slack in flight. An argument could be made that IF the main hang loop broke, you'd rather have the backup in front because the most likely scenario in which you'd break the main would be pulling high positive G's, and in that case you'd rather have the pitch trim become more nose down than become more nose up, but on a Falcon 2 that's not really a consideration. As far as where the backup "usually" goes, we usually put it behind the main because that's usually where there's room for it. If the main is properly maintained, and periodically replaced, it is never going to fail anyway, so the backup is sort of pointless. Years ago we didn't even put backup hang loops on our gliders (there's no other component on your glider that is backed up, and there are plenty of other components that are more likely to fail, and where the failure would be just as serious), but for some reason the whole backup hang loop thing is a big psychological need for most pilots.
It was a total pander to the stupidity of the assholes who populate this sport.

- Tell us what the logic of the hang gliding aerotow weak link is. What's it supposed to be doing for us and what strength we should be using so that it works properly when we need it to and won't inconvenience us at an overly safe rate?
...pilots' lives will be saved.
Name one whose life was lost because he didn't have a "proper" backup configuration. Garck would've been an example but he wasn't even very badly injured. On the other hand I can name you a whole shitload of pilots who've been killed and seriously mangled 'cause they weren't hooked into ANYTHING at launch. I can name you two tandem thrill rider chicks who were dropped to their deaths 'cause they were launched like:

Tell us what you've EVER done to help get that MAJOR killer and maimer issue addressed.

And I can also name several who were fine from the waist up but died 'cause they didn't have their leg loops. How come nobody advocates backup leg loops to increase our odds of survival? And if you're platform or dolly launching your leg loops won't matter until/unless you go upright for landing. Tow launch sites are virtually always ideal wheel landing sites. How come nobody advocates wheel landing in those environment as a safety measure to eliminate that means of killing oneself?
No pilot flying for fun needs to reduce drag to this degree.
There are two reasons to fly a hang glider:
- for fun
- to illegally rake in dough selling tandem thrill rides under the guise of providing instruction

Fuck the second so for the purpose of this discussion EVERYBODY who flies a hang glider does it for fun and fun alone.

- The more performance we have the more fun we have ('cept maybe on final in a tight field when we suddenly discover we have a tailwind). Check out Ryan's suspension:

Don't see much flapping in the breeze there, do we? From the carabiner up anyway. He can't fly a racing pod 'cause he needs to ball up to get the speed he needs to initiate maneuvers.

- Sometimes we fuck up and get ourselves in situations in which we're not having fun and need every ounce of performance we can get to avoid going down in the trees (BTDT), water, powerlines.

So don't tell me that it's OK to add drag to all gliders for 100.000 percent of their flying time to up the odds of survival of someone who makes a critical mistake when shitrigging a critical system of his glider.

Also... Name one individual who thinks it's more fun to fly an extra parasitic drag glider.
Most pilots plow through the air head-up anyway...

a bit under three seconds before things go seriously south. Is that what he's doing? Show us some shots to better illustrate your point.

- ALL pilots are gonna make temporary adjustments for comfort during intervals in which performance isn't an issue.

- We fly slowly / well under max L/D when we're milking lift. Both glider, by definition, and pilot, of necessity, are pitched up. But when we're flying down or up wind to the next thermal cloud we're all doing everything possible to minimize our profiles.
...making the idea of trying to hide the BU drag in the main ludicrous.

...stupid draggy crappy Flight Park Mafia excuse for an AT release? Is that enough drag to make it not ludicrous for you to go pro toad?

- Pretty hard to find a photo of you flying with either wheels or skids.

- The idea of reducing drag in ANY aircraft is NEVER ridiculous. What's fuckin' ridiculous is flying around for the entire life of the glider with a foot or two of slack webbing held perpendicular to and fluttering in the airflow for every glider on the planet because it will likely defuse a one-in-a-million shitrigged equipment induced fuckup like this one.
Comp pilots will always trade safety for performance...
Oh really? So an ultra clean carbon topless bladewing with a comparable racing pod is automatically more dangerous than a Falcon 2 with a cocoon? Do we have any data to support this assumption?
...but rec pilots...
What? Comp isn't rec? The comp pilots are doing this professionally? That's how they're earning their livings? Cleaning up with the big purses from national and world comps?
...should not be mislead into thinking we need this minuscule drag-reduction feature at the detriment of safety.

The most significant aerodynamic revisions to the Sport 3 are a redesigned sail and stability system that together provide for a tighter-flatter sail and allow for lower sprog settings. This lower twist sail both significantly improves high speed performance and reduces pitch pressures at high speed. These changes also contribute to improved handling across the speed range and range of VG adjustment. The Sport 3 can also be configured with carbon fiber raked tips that increase the effective aspect ratio, reducing induced drag to further enhance low speed performance.
Don't even mention it. And everything they have on the issue in the fuckin' manual:
The main / backup hang loops. Verify that the main hang loop spreader bar is positioned just below the bottom surface.
By the way John... You lost the world consecutive loop record to Chad Elchin 'cause your glider was kingposted and his wasn't.

- Speaking of misleading recreational pilots... You wanna know what the single most devastating misinformation in the sport is?

Steve Pearson on landings
Steve Pearson - 2012/03/28 23:26:05 UTC

I can't control the glider in strong air with my hands at shoulder or ear height and I'd rather land on my belly with my hands on the basetube than get turned downwind.
Doing anything about that one?
I know a guy who's main broke while he was looping.
Which means he was flying with a main probably good for only three Gs max on a glider certified for six. Anybody besides me see a problem with that?
The separate BU saved him.
How? Shouldn't the separate BU have been hit with the same three Gs plus the jolt? Or was the backup in better shape than the primary? (Total fuckin' bullshit.)

And more total fuckin' bullshit... There was OBVIOUSLY something SERIOUSLY wrong with his main and he was OBVIOUSLY SERIOUSLY negligent in preflighting his wing - before going AEROBATIC no less. Anyone who ISN'T full o' shit is gonna tell us what the issue is. But you're presenting this incident as if everything was being done right and his main blew for no reason. It's deliberately misleading and bullshit like this intimidates the hell outta tons of Zero, One, Two, Three level pilots and helps cripple their endeavors to become competent and comfortable flying hang gliders.
I knew a guy who died because he didn't hook into his extension correctly around the time the first integral BUs were introduced. I'm sure that he would have extended the BU had there been a separate BU strap hanging there in front of his face while he was hooking in. That's why we need a separate BU.
Go fuck yourself. I knew a guy - briefly - who died on an earlier edition of the same model glider Garck was flying because he'd been instructed and signed off to Three level 100.00 percent in violation of u$hPa SOPs which mandate a hook-in check just prior to launch. It's a total no-brainer that this guy was instructed and flew likewise. And as far as I'm concerned this guy was dead for the purpose of the exercise every foot launch he ever made.

Also... You knew two guys from two serious incidents and you give us zero names.
The idea that hooking your harness into your glider before you climb in will prevent launching unhooked is a fallacy, because we humans are fallible.
So let's engineer our gliders and harnesses to provide maximum protection from every mistake every idiot who's ever proned out in a harness has ever made and ignore any and all possible and obvious downsides.
As long as there is a carabiner that can be unhooked, an unusual situation will arise when the pilot (a human being) will unhook and forget to hook back in.
'Specially if he's an Aussie Methodist total douchebag who can't conceive of a situation in which anyone in a harness could possibly not be safely connected to a glider with his leg loops engaged.
There is no foolproof way of preventing unhooked launches unless the harness does not detach from the glider.
And there's no way to transport a glider any range beyond walking distance unless the harness DOES detach from the glider. So let's not head much farther down that avenue.

But as far as I'm concerned the lift and tug hook-in check you're about to bring up COMBINED WITH the assumption that you are never hooked in and the appropriate fear level IS a totally foolproof way of preventing unhooked launches 'cause it takes the fool totally out of the equation. Only a totally fool...

AL's Second flight at Packsaddle how it went
Rick Masters - 2011/10/19 22:47:17 UTC

At that moment, I would banish all concern about launching unhooked. I had taken care of it. It was done. It was out of my mind.
...EVER at ANY moment banishes all concern about launching unhooked. That's the one thing that every motherfucker who's ever been embarrassed, battered, mangled, killed launching unhooked has in common with every other motherfucker who's ever been embarrassed, battered, mangled, killed launching unhooked. They were all 100.00 percent positive that they were all 100.00 good to go.
The best way I have seen that reduces the likelihood of launching unhooked is "Marginal" Mark's method of lifting the glider until you feel the leg loops pull up on your legs...
- Oh, that's "Marginal" Mark's method.
-- Everybody knows who 'Marginal" Mark' is (Mark Lilledahl, San Francisco, Funston) so no need to elaborate further.
-- He:
--- was the first guy to come up with this idea somewhere back in the mid Seventies
--- has been a tireless advocate of the Marginal Mark Method over the decades and has undoubtedly saved untold scores of lives

- Is Marginal literate? Is there an article or post of his on any issue, hang gliding or not, anywhere? And how come he's not participating in this discussion?

- Name one:
-- instructor who conforms his program to Marginal's technique.
-- individual who's modified his procedures as a direct or indirect result of Marginal's influence. Yourself maybe?

- People with enough in the way of brains to incorporated this procedure generally also have enough in the way of brains to understand what a total load o' crap the backup loop is.

- Where can we go to find a video of you or one of your products executing this procedure? We notice you're saying ...The best way I have SEEN... while not saying you've ever once actually INCORPORATED it. And it's a total no-brainer that you HAVEN'T. And you're selling lessons and never teaching any of your students this procedure - or anything else that complies with u$hPa's near four decade old hook-in check requirement.

- Fuck you and the horse you rode in on for so conspicuously ignoring my decades of work and efforts on this issue. Also... Doug Hildreth plugged this issue in the magazine from 1980/11 through 1994/03, Dennis Pagen after an unhooked launch at Morningside put in a few words 1990/01 and on, Rob Kells put in a good passage diluted with a lot of politically correct crap 2005/12 after Bill Priday. Marginal Mark my ass.
...then launch in that condition.
Right. It's CRITICAL that you not only do the lift and tug within a couple seconds of commitment but that you also hold the suspension taut until your wing starts taking over the job.

There's just no telling what could happen as you're starting your run.
This also insures that you are in your leg loops.
- At the expense of giving you a false sense of security.
- You actually only need one of them.
This method does take a fair amount of strength.
Yeah. And the hydraulic hoist you used to load the glider on your shoulders in the first place will be way back in the setup area. Pure unmitigated bullshit. I've heard two hundred percent of the moronic reasons why lift and tug is ineffective, not doable, dangerous, gives one a false sense of security but strength requirement is a new one and in a class all by itself. If you don't have the strength to lift 75 pounds of glider - the most you're ever gonna hafta do and then only in dead air - the few inches it takes to tighten your suspension then you have no fuckin' business foot launching.

Geometry which makes the procedure problematic to impossible in light or zero air - different and legitimate issue. But you doesn't mention it and that's more really excellent evidence that you don't teach or even make your students aware of it.
If you are not strong enough to hold the glider up while you launch, you should at least do a quick lift to feel the leg loops tighten just before you go.
It won't offer you the kind of bulletproof protection hold the glider up while you launch does - you could still be distracted, unhook, forget to hook back in while you're accelerating down the ramp - but it's certainly better than nothing.

This is currently - and will undoubtedly remain - the most extensive mainstream response to this incident. And I've been working on this dissection on and off since my previous post. What an incredible load o' crap.

Wilbur and Orville, Kitty Hawk, 116 years ago this morning. Look at how far backwards hang gliding's been able to take things over the course of a few decades.

The flight that almost killed me
Bob Kuczewski - 2019/12/18

Without permanently attaching the harness to the glider, there is no method to prevent this ... other than extreme vigilance.

I know, the Aussie methodists will say you can't launch unhooked if you always attach the harness before getting into it. But that's just like saying you'll never launch unhooked if you always hook in before launch. They're both fool proof ... except when you don't do them. How many Aussie proponents spent years climbing in and out of attached harnesses only to launch unhooked the first time they "cheated" for a quick camera adjustment or a last minute drink of water?

The lift and tug method ("always launch with a tight hang strap") is also very good (when safe), but we saw one of its failure modes right here in this video.

Let's face it, ALL of the so-called "fool proof" methods have their failure modes. Complacent reliance on any single method will eventually bite each of us. Extreme vigilance for ourselves and our flying friends is the price we must be willing to pay ... to fly like birds.
Without permanently attaching the harness to the glider, there is no method to prevent this ... other than extreme vigilance.
If you permanently attach the harness to the glider it isn't hang gliding - unless your glider's hangared at an AT operation and that's the only place you ever fly.
I know, the Aussie methodists...
That's MY copyrighted derisive term for these assholes.
...will say you can't launch unhooked if you always attach the harness before getting into it. But that's just like saying you'll never launch unhooked if you always hook in before launch.
Exactly. Also exactly like saying if you always kiss the Magic Feather you keep in your upper left harness pocket after connecting in the setup area and never unhook until after you've landed you'll never launch unhooked.
They're both fool proof ... except when you don't do them.
Or can't - because your particular configuration and/or set of circumstances makes it impractical, impossible, dangerous.
How many Aussie proponents...
...all of whom are assholes and total morons...
...spent years climbing in and out of attached harnesses only to launch unhooked the first time they "cheated" for a quick camera adjustment or a last minute drink of water?
They tend not to cheat. They usually fuck up when their particular configurations and/or sets of circumstances make it impractical, impossible, dangerous.

How To Get The Right Hang Height - Wills Wing
Note that hang loops must be ordered through an authorized WW dealer - they cannot be ordered for retail direct sale.
The lift and tug method ("always launch with a tight hang strap")...
Get fucked. It's not a METHOD - it's a PROCEDURE - and it doesn't have shit to do with launching with a tight strap. You quote me EVER advising to foot launch with a tight strap. Hell, quote ANYBODY advising to foot launch with a tight strap. Even in hang gliding I don't think there's anybody stupid enough to state something like that. No, wait...
John Heiney

The best way I have seen that reduces the likelihood of launching unhooked is "Marginal" Mark's method of lifting the glider until you feel the leg loops pull up on your legs, then launch in that condition.
I stand corrected.
Bob Kuczewski - 2017/08/06 04:36:50 UTC

The pilot who I asked about towing was John Heiney and he definately knows towing.
As a matter o' fact the dictionary definition of the verb "tug" strongly implies a momentary action. If one MEANT "always launch with a tight hang strap" one would SAY "always launch with a tight hang strap". Lift and tug means and is taken to mean jerk the glider up until it stops then launch however the fuck you deem best.

Lift and tug is the first action in your launch sequence and it's done before forward motion is initiated - just like a passenger jet's hook-in check is to radio the tower for clearance before it starts rolling onto the downwind end of the runway where bad things can happen.

When a little kid TUGS on a parent's sleeve it's a repetitive jerking action to get his attention. It's not a PULL to start him moving in a direction. A dog doesn't TUG on his leash to try to speed things up towards a desired goal. He PULLS like he's doing the Iditarod.

(I'm getting better at identifying and debunking your infuriating misrepresentative crap.)

And it's really not so much about lift and tug either 'cause not all individuals in all configurations and/or circumstances can do it. It's a mindset of always being afraid of being / always assuming you are UNhooked JUST PRIOR TO LAUNCH. This:

does the same trick. Nobody who's been afraid of launching unhooked a few seconds prior to commitment has ever launched unhooked. If one's afraid of doing it one will think and check. And if one's not afraid of doing it then fine... He should go ahead and do the gene pool another favor.
...is also very good (when safe)...
Here we go again...

It's ALWAYS safe. If it's not safe you:

- have crew. And if you have crew it's safe. Catch-22.

- WILL BE in tight suspension mode in another three quarters of a second anyway. And then you're gonna get killed whether you're hooked in or not anyway.
...but we saw one of its failure modes right here in this video.
Bullshit. There was no failure on this flight. Garck launches totally successfully at 1:33, climbs out in the lift, gets 0.4 miles southwest down the bluff, turns back, foot lands successfully on the beach after one minute and twelve seconds. His velcro suspension system holds for 58 seconds which has gotta be a world record duration for that configuration. Tell me where the failure is. I'm quite certain Allen sustains much more serious injury on this:

situation. A bit counterintuitive, ain't it?

And compare/contrast Zack Marzec at Quest on 2013/02/02. Launched with a conventional suspension system using AT equipment that Quest had been perfecting for twenty years, used a weak which infallibly and automatically released his glider from tow when the tow line tension exceeded the limit for safe operation, only stayed airborne about a quarter the time and nowhere near the distance - out and back - that Garck did, landed way harder than Garck with significant damage to the glider and substantial damage to the pilot.

And nobody did anything wrong on that one and there's never been an advisory to alter procedures and/or equipment. So how can we POSSIBLY consider any aspect of Garck's flight a failure?
Let's face it, ALL of the so-called "fool proof" methods have their failure modes.
Bull fucking shit.

isn't a METHOD. It's logic and a mindset which is constantly doing threat assessment. It doesn't fail and you can't cite a single incident from anywhere in the world history of the sport to indicate otherwise.

- Quote me EVER so-calling lift and tug "fool proof". I once launched a dune soaring flight with a partial hook-in. The wind was scary strong, I had a mom and a kid on the sidewires, I was afraid of losing the glider, I spun around really quickly to snap in. When the wind's like that EVERYBODY launches with a tight strap 'cause you don't do forward motion to launch. You go straight up - maybe backwards a bit.

- I knew beyond any doubt I was connected 'cause I soared a few passes and landed connected to the glider normally. I didn't find out I wasn't SAFELY connected until I turned around to unhook and discovered I was already halfway there. I didn't preflight the connection 'cause I was distracted by the circumstances and scared. And that's not a mistake anybody ever makes twice.
Complacent reliance on any single method will eventually bite each of us.
Right...

- We lift and tuggers complacently rely on lift and tug to guard against un and partially hooked launches. We don't actually make the connection and look at it during setup and preflight. We just hop up on the ramp and assume everything's OK unless the glider keeps going up. It's absolutely amazing any of us survive more than half a dozen mountain launches. And I've always suspected that prostate cancer was just the cover story to handle Rob Kells' suspiciously untimely death.

- Treating the gun as if it's always loaded is a complacency thing. It's just a matter of time before you accidentally blow someone's head off.
Extreme vigilance for ourselves and our flying friends is the price we must be willing to pay ... to fly like birds.
- Oh right.

- Garck didn't almost buy it 'cause he shitrigged his suspension to make it fit and fucked up his connection to it. He almost bought it 'cause his vigilance wasn't extreme enough. Ditto for...

...the guy assisting him.

- We're gonna get extreme vigilance out of a culture that flies backup loops, won't load test sidewires 'cause they can't do it without grinding them into sharp rocks, won't use the first half of the runway for landing 'cause they'd inevitably clip the downwind end fence, flies for decades with a one-size-fits-all Standard Aerotow Weak Link which will keep them from getting into too much trouble, thinks that a towline transmits pressure from the tug to the glider.

- What kind of response did you get from Kevin Kader and Joe Greblo when you asked (2019/12/04 21:57:52 UTC) about the former's career ending Kagel launch crash?

- I have NEVER employed extreme vigilance in setting up, preflighting, hook-in checking foot launching my glider. Common sense procedures, routines, situational awareness, responses are plenty enough to do the trick for me. I reserve something on the order of extreme vigilance for when I'm circling in a dense mass of thermalling gliders.

- Bullshit. If extreme vigilance were all that important in this sport nobody would survive participation more than three or four weekends. We need twenty times the vigilance driving to and from the site than we do setting up, preflight, flying our gliders. The reality of the situation is that stupid incompetent douchebags tend to do just fine heavily participating for decades.

Frequently Asked Questions
What will keep the US Hawks from becoming another USHPA or HGAA?
You will ... hopefully. The price of freedom is eternal vigilance. Everyone has to do their part once in a while. If you see something that's not being done correctly, then it's your duty to speak out. One big difference between the US Hawks and other organizations is that the US Hawks really does honor the free speech of its members.
But you've gotta be a MEMBER for Emperor Bob to really honor your free speech. And Emperor Bob controls who gets to be a member and what the member is and isn't allowed to say without getting basemented or banned.

Fuck honoring free speech. Free speech includes lies, misrepresentations, half truths, making up your own numbers to support your position, going deaf when somebody's talking to you explaining that two plus two doesn't equal seven. I respect speech that merits respect regardless of the venue and will not tolerate speech posted to Kite Strings which violates the conditions Zack specified upon the forum's founding.

If The Bob Show weren't just another dictatorial hang gliding cult you'd be getting called out on this bullshit. But that ain't gonna happen.

Kite Strings got founded 'cause Zack knew things smelled funny, thought I sounded like I knew what I was talking about, wanted to here me out without having the conversation sabotaged by assholes like you, Rick Masters, Sam Kellner, Charlie Schneider... People have come here, learned, radically altered their flying, equipment, procedures, mindsets. Can you point to anything like that?

Most of your guys are united only by a common hatred of u$hPa but I'm not holding my breath waiting for something substantially better to emerge.

And as I post this there's been zero response to Bob's post anywhere save for here - YouTube, Bob, Jack, Davis, Grebloville...
