Problem solved - assholes. Keep up the great work.Accident Review Committee [ Analysis > JERRY KELLER ] - 2020/11
Are You Hooked and Strapped In? One of the first and last things you need to check before launch is: Are you hooked in with your leg straps connected? We all know it's critical, yet we still see accidents where pilots forget this vital step. Launching unhooked is one of the most serious mistakes we, as pilots, can make, and the consequences can be fatal. If you're not properly hooked in, controlling a hang glider or paraglider is nearly impossible.
Being "hooked in" means several things. For hang gliders, it means your harness is properly attached to the glider and you are attached correctly to your harness, i.e., leg straps, chest straps, and zippers. For paragliders, it means you are properly attached to your harness, including leg straps, waist strap, and sternum/ breast strap, and connected securely to your risers.
We all need to make this our number one safety check before launch. Unfortunately, our current technology does not have an "idiot-proof" way to ensure these items are attached before flight. We must rely on our personal preflight methodology to make sure it happens. To be clear, modern paraglider harnesses have what is commonly called a safe T system, which provides one strap between the pilot's legs as soon as the waist strap is connected. Still, this does not prevent pilots from launching without anything connected. Sometimes a flight deck can hide the fact that nothing is connected.
Keeping your harness connected to your paraglider while packing up facilitates efficiency on launch and safety in the preflight. As for preflight, make checking leg loops, waist strap, sternum strap, and chin strap when putting on your harness and helmet the first four items in your preflight checklist.
Some common reasons for hook-in failure are being rushed to launch, being the last person to launch, getting distracted during your preflight, and (for hang gliders) unhooking from the glider after a hang check and staying in your harness. Other reasons for a mishap are not having a consistent preflight methodology and failing to do a final hang check (hang gliders) or preflight check (paragliders) just before launch. Finally, there is no substitute for a buddy check. Always keep an eye out for your friends and let them know when you see they've missed something!
My hang gliding hook-in accident was in 1974 at a site in Southern California called the Domes (not currently flown). There were a lot of pilots around waiting for a good cycle to launch; since I was waiting a long time, I decided to unhook but stay in my harness so I could move around and check conditions. Once it got good, everyone was in a mad dash. In the rush, I forgot to hook in and launched. I immediately realized I was not connected to the glider and decided to let go and fell around 15 feet. Fortunately, the launch was a steep slope with gravel, so the impact was not terrible but resulted in a trip to the hospital to address a deep cut in my knee and scrapes on my face. I was lucky; if it was a cliff or rocky launch, I might not be here today. From that incident, I learned a few lessons that I follow to this day: Always do a hang check before launch, never allow yourself to be rushed, and never unhook from the glider and walk around in your harness.
Some helpful suggestions to avoid hook-in accidents:
- Make multiple hook-in checks part of a standard preflight.
- Have a consistent methodology for preflight and hook-in checks; follow it religiously.
- Avoid distractions when doing your preflight. If someone wants to talk to you, politely tell them to wait until after you've finished your preflight.
- Don't rush or shorten your preflight because the conditions are getting good; you'll get your chance.
- For hang gliders, connect your harness to your wing as part of your wing assembly process, get into your harness while it's attached to your wing, and never disconnect it.
- Never put on your harness without being attached to the wing.
- For paragliders, either have the harness completely buckled or take it off—nothing in between (all the way on or all the way off).
- Complete one final hook-in check just before launch: hooked to the glider, hang straps straight, and hooked to the harness. Also have someone help and witness.
- Just before launch, pull up on the hang strap (hang gliders) to feel the connection at the wing and in the leg straps. For paragliders, feel the leg straps coming tight as you run and if they aren't connected, put your hands up so the glider can fly away without you. There is a long history of this working to prevent pilots from flying away without leg straps attached.
- Watch out for other pilots and check each other often.
- Permanently install high-visibility "Hook In" placards at launch.
- Attach a "Hook In" memory aid to your glider or somewhere it is visible as you get ready to launch.

Universal agreement that this is a fantastic must-read essay. Somebody providing a scrap of evidence that it's ever made the slightest positive difference in anyone's flying career...You are encouraged to re-read the excellent article by Mike Meier, "Why Can't We Get a Handle On This Safety Thing?" (http://www.willswing.com/why-cant-we-get-a-handle-on-this-safety-thing/). Although published in 1998, the risk mitigation analyses and approaches in the article are timeless and still applicable.

We discuss this stuff a lot more as well. We vet more ideas. This isn't just "neat stuff" to us... it's very real and we deal with it every day.
It's not "us" that has the track record... it's our process.
We're people just like anyone else. And that's the point. THIS is how we do it... normal, fallible humans... and it bloody well works.
So I don't give much credence to something that someone doesn't agree with about what we do for some theoretical reason.
And please don't trouble yourself to put anything in quotes. We'll eventually figure out that it should be:Davis Straub - 2020/11/25 02:22:59 UTC

Your Individually Rational Choice Is Collectively Disastrous
Stopping the virus from spreading requires us to override our basic intuitions.
But some activities, including dangerous ones, provide negative feedback only rarely. When I am in a rush, I often cross the street at a red light. I understand intellectually that this is stupid, but I've never once seen evidence of my stupidity. In fact, every time I cross on red, the world sends me a signal that it's safe: After all, I've never (yet) been hit by a car! So I keep crossing on red.
Exposure to COVID-19 works the same way. Every time you engage in a risky activity--like meeting up with your friends indoors--the world is likely to send you a signal that you made the right choice. I saw my pal and didn't get sick. Clearly, I shouldn't have worried so much about socializing! But that is just as wrong as thinking that jaywalking is safe because you haven't yet been hit by a car.

I've had no problem releasing my barrel release hundreds of times.

I got clobbered and rolled hard right in a split second. I have never had a lockout situation happen so quickly and dramatically and had no chance to release as I have always thought I could do.
Lauren Tjaden - 2008/03/23 22:20:15 UTC
When Jim got me locked out to the right, I couldn't keep the pitch of the glider with one hand for more than a second (the pressure was a zillion pounds, more or less), but the F'ing release slid around when I tried to hit it. The barrel release wouldn't work because we had too much pressure on it.
And Paul and Lauren are always nice and high when this shit happens. So nobody ever considers this as negative feedback to the slightest degree.When I am in a rush, I often cross the street at a red light.

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
Bullshit. There might be a case to be made that the jaywalker is LESS likely to be hit because he knows he needs to better tuned into what's happening inside of the critical radius.But that is just as wrong as thinking that jaywalking is safe because you haven't yet been hit by a car.
...ever make that mistake again - just like Steve Parson, Jon Orders, Interlaken...Rob Kells - 2005/12
Each of us agrees that it is not a particular method, but rather the fear of launching unhooked that makes us diligent to be sure we are hooked in every time before starting the launch run.

Pilot is no injury.
Launch is:Jae Yong Hwang
I am the main character in this video
This place is called Pyeongchang in Korea
I rolled about 30~40 meters away, but there was no injuries.
Because of the wind, I was in a hurry this day.
The result is as you can see.

I lift my glider so that I can feel the straps get tight.
If you can't feel the straps go tight, how else do you know you are hooked in?
Pilot just lets the glider rest on his shoulders. Bad form.
Great. And Yours Truly...I lift my glider so that I can feel the straps get tight.
Well...If you can't feel the straps go tight, how else do you know you are hooked in?
What pilot? Did we see anyone other than the paraglider guy actually get airborne in that clip?Pilot...
Kept it out of Emperor Bob's Turbulent Jet Stream pretty effectively, didn't he?...just lets the glider rest on his shoulders.
Again... No worse form than the half dozen motherfuckers standing around watching the bad form like it was totally normal - all of whom were in much better position...Bad form.
...to Davis for me.Davis Straub - 2005/10/01 23:12:07 UTC
Well, very simply we could make a new rule for competition. If you are seen in your harness but not hooked into your glider you are automatically disqualified.
Yep...Andrew Vanis - 2020/12/30 02:35:20 UTC
anyone else notice the model of the glider
Bullshit. His mistake wasn't failing to hook in before moving to launch. ANYBODY can be mistaken about his connection status. Motherfucker's near lethal mistake was to adapt a procedure of NEVER doing hook-in checks - and joining a culture of other douchebags totally incapable of getting the concept through their terminally thick skulls.I shouldn't be smug, all of us are available to make a mistake
Extremely useful, Davis. As always.Davis Straub - 2020/12/31 01:38:42 UTC
Lie down in the cart. If you hit the ground you are not hooked in.

It disturbs me that no one stopped this guy from launching. There were other hangies around, probably watching the launch. I think I would have noticed and said something if I had been there.
How much does it disturb you that the hook-in check is a totally alien concept to this culture?It disturbs me that no one stopped this guy from launching.
Did you actually watch the video?There were other hangies around, probably watching the launch.
Versus noticing and NOT saying something if you'd been there. Granted - there's no shortage of individuals in this sport... It's too bad that it was Zack Marzec who had to be the one to finally nail the coffin lid down on the Infallible Standard Aerotow Weak Link but that was the only way that threat and Hewett were ever gonna be mostly eliminated from AT culture. Rooney or Jack solo at Henson in dangling carabiner mode... Keep your mouth shut and do both the sport and gene pool a massive favor.I think I would have noticed and said something if I had been there.
Much more fun to target and bully individuals who aren't adhering to majority religious cult beliefs and practices than to spot and deal with actual problems - ain't it Adam? And I'da told you motherfuckers to either put in your HGFA SOPs or mind your own goddam business. Hell... Both.Adam Parer - 2012/07/15 05:01:12 UTC
We are militant with this sort of thing down here. Anyone seen walking around in their harness unhooked are immediately pulled up, by everyone. Not sure of the reaction if the justification was to keep the harness clean or scratched free, or that it was uncomfortable to bend over because there was extra weight to carry, or they have a sore back. It would probably be advice along the lines of 'harden the f^&k up'.
You don't actually catch them when they're walking around in the harnesses, under gliders unhooked, launching unhooked - REPEATEDLY. You're probably more likely to catch an unlocked carabiner connected to the strap than one dangling behind the harness at the edge of the cliff.William Olive - 2010/01/28 04:50:53
Phil Beck did this twice (or was that three times?) in a day at Hexham (Victoria) one time while foot launch aerotow testing gliders. Of course, with a swag of gliders to test fly, Phil would unclip from the glider he'd just landed, then clip into the next one to be tested.
Except, at least twice, he didn't clip in.
