Another fatal accident

I hear that Jesse got popped by a thermal coming in to land. I am reminded of Joe Julik's fatal landing accident from last year.
Me too, Jonathan. Both highly experienced pilots in the sport since the turn of the century or farther back, both coming in to Happy Acres putting greens doing absolutely everything right, both overwhelmed by thermal activity too freakishly intense to have been survivable by any of the best of us.

Pretty much the same as Zack Marzec, 'cept his was near the other end of the flight.

Seems to be a trend as the sport progresses... Higher and higher percentages of fatal accidents in which everything was being done right - no recommendations for better assessments of situations, techniques, courses of actions, emergency responses. Not surprising, really - we've all been such keen and highly motivated students of aviation for so many decades that there's very little left that we don't thoroughly understand and haven't properly dealt with.

Probably a good idea from now on to just post the names, dates, and sites and just assume that what happened was inevitable and any discussion of any details would be totally pointless - not to mention disrespectful to the pilot, relatives, and many friends who had to witness the tragedy.

Student Pilot Ridge Soaring Crash - Watch & Learn
Mike Badley - 2015/10/27 16:55:33 UTC

Pure flight without any electronics is the best way to just focus on the task of flying without distractions.

But, here is the list of stuff that can add up to mess you up.

1 - Vario
2 - More complex vario with windspeed, altimeters, timers, speed to fly, waypoints, etc.
3 - GPS
4 - Radio, including the PTT wiring to headset and fingers.
5 - I-pod for 'tunes' to play while just ridge soaring away.
6 - Camera
7 - Multiple cameras
8 - Towing lines
9 - Hydration tube
10 - wheels and barmitts, etc.

I got a few more 2nd hand details today about Tim's accident that I wanted to share. It's my understanding that Tim had been in the air for over 2 hrs before his accident. He had flown from Henson's to Whitwell and was returning when the storm came up. The landing field was between Tim and the storm. Tim tried to make it to the landing field before the storm and both arrived at the same time. Several pilots tried to contact him on the radio and advise him to fly away from the storm but Tim's radio was not functioning at takeoff. I'm sure he would have taken the advise if it was available and the outcome could have been different. Please guys, don't ever fly toward an approaching storm. You closure rate can exceed 100mph. Gust fronts can be miles in front of a cloud. Also know the value of a radio. I'll miss you Tim.

Gerry Smith was doing big slow "S" turns at about 300' AGL -- and why not? The flag showed a strong stable breeze and the air he was in was smooth. It was a great day at Big Sur and he was having fun. This scared those of us who had already landed because we know about the rotor. Gerry had no idea.

At about 70' AGL he decided to land and began his regular approach. I know this approach well, because after seeing him perform consistently good landings I adopted it as my own. First, you climb to the upright position at about 70' AGL on your base leg, with a slight turn toward final so as not to be bumped downwind. Second you turn your glider into the wind and begin final approach. Third, you pull in the bar. I know Gerry pulled in the bar because I saw him do it. Granted, you can't pull it in very far but he did pull in.

About | Hyner Club
With launch facing WNW, Hyner offers great flying during post-frontal days but can also be launched from S to North winds due to the round shape of the mountain. Hyner is a great place for first high flights, intermediate pilots who need to practice launches/landings and advanced pilots who enjoy challenging thermals with a terrific view.
And a few other thoughts on the issue...

Another fatal accident
Dave Gills - 2015/10/12 11:54:41 UTC

The trees at Hyner are very tall. (75' ?)
This happened last year but the pilot managed to get it sorted out.
Charles Fager - 2015/10/12 15:10:30 UTC

It was beautiful day in the mountains...
Dave Gills - 2015/10/13 00:28:26 UTC

The Hyner LZ is just weird to start with.
David Stevens - 2015/10/13 00:55:56 UTC

I've come in so hard some times on wheels it's not even funny. Several times I've been turned almost 45 degrees towards the trees when below the tree line. There have been a lot of close calls there. I think it's time to cut the trees back. The lz is getting thinner each year and the trees are getting taller.

Sometimes the safest thing to do seems to be slicing through the slot on a high speed slipping turn off final. That way you get below the turbulence from the tree line as quick as possible with a lot of speed. But that is scary in it's own right.
NMERider - 2015/10/13 01:07:15 UTC

Your video is excellent. It shows how unforgiving your LZ can be.
Dave Hopkins - 2015/10/13 02:28:27 UTC

It's a tough LZ. Very unforgiving of a high approach.
I hate flying a slot LZ . They are almost always turbulent and it is hard to know if we are going to snag a tree. We have to look down the middle of the slot regardless of how much we are getting rolled and yawed. The slot at hyner is curved so that complicates things.
Rodger Hoyt - 2015/10/13 17:06:30 UTC

That's a fundamentally flawed landing field. Too narrow, too much tree rotor. I wouldn't go near that even as an emergency bailout (especially with a 42-foot span rigid). It's just a matter of time until another accident there.
David Stevens - 2015/10/13 21:12:03 UTC

It can get highly turbulent there, especially mid day. The air doesn't always agree with your plan. According to those on the ground Jessie was coming in on a long final with plenty of speed when he got turned at about tree level by thermal activity. He corrected but his wing tip clipped a tree.
David Stevens - 2015/10/13 21:15:14 UTC

Here's an example - this isn't a topless but you can see how scary it is.
Dave Gills - 2015/10/14 00:35:57 UTC

Maybe it is time to revisit the tree issue.

Honestly...Hyner is my last choice in sites.
I have two other West facing hills that are closer and not nearly as dangerous.

Charles Fager - 2015/10/12 15:10:30 UTC

Hopefully the Hyner club president will come out with an official statement when appropriate.
The crash was three weeks yesterday, I just now pulled:
Hyner is a great place for first high flights, intermediate pilots who need to practice launches/landings and advanced pilots who enjoy challenging thermals with a terrific view.
so I guess we have our official statement from the Hyner club president when appropriate.

A bit odd that not one single poster on a mainstream forum supports that characterization.

Two dickheads on that Jack Show thread, Tom Lyon and Dave Hopkins, who both advocate long finals and, respectively, condemn low decisive turns and being prone on the control tubes connector bar during final. And no other Jack Show dickhead has ever called either of these dickheads on those positions.

Then we have these quotes:
Dave Gills - 2015/10/13 00:28:26 UTC

Many people fly their downwind leg over the trees and do a slipping combined base/final turn (180) into the slot.
...
And wheels to land on when flags start pointing at each other. Image

Dave Gills - 2015/10/13 20:41:32 UTC

Entering a slot on the downwind side has less crosswind rotor because of the movement of the air up and out of the slot.
You will get a bump when you dive in but you will be going fast.
David Stevens - 2015/10/13 21:12:03 UTC

If we do S's we do them at the end of the field so that you can turn to final quickly. Most often the DBF or modified 180 degree Base/Final is used to get below tree line quick.
from that thread. Every one of them implies, states, and/or advocates staying prone on the control tubes connector bar until at least well into final. Three of them STATE low, fast, decisive turns onto final. And not one motherfucker takes the least issue with any of this.

We have a total of two representative videos posted:
David Stevens - 2015/10/13 00:55:56 UTC

Not a great landing but you can see the LZ/approach here:

David Stevens - 2015/10/13 21:15:14 UTC

[video][/video]
Both of them show experienced flyers doing competent approaches in interesting air - which they characterize as rock and roll, weird, turbulent, scary; both include low turns around final time - one done BY the pilot, the other done...

...they're in ground effect at which time both make totally unnecessary and potentially dangerous transitions to the control tubes. And the one in the nastyish air stays prone and rolls to a stop on the Hyner Happy Acres putting green on his dinky little Wills Wing plastic placebo wheels.

AND THERE'S NOT ONE FUCKING WORD of criticism; respectful recommendation; Dude, you really should've/shouldn't have...

This is such a totally awesome smoking gun fatality and discussion. Thanks bigtime Jesse. You've done to safe landing theory exactly what Zack Marzec did to safe weak link and pro toad bridle (bridal) theories.

It's very seldom safe to be slicing THROUGH the slot on a high speed slipping turn OFF of FINAL. Maybe slicing INTO the slot with a high speed slipping turn ONTO BASE.

Bill Jennings - 2015/10/13 00:15:31 UTC

For us green pups, would more speed on landing help when you get popped up by a thermal close to the ground?
I dunno...

What did they teach you at Lockout before they cleared you for mountain flying four and a half months ago? And how come your instructor isn't participating here on this fatality thread to fill in the critical stuff he couldn't be bothered to teach you at the time? Too stingy on the tip? Fifteen percent instead of twenty?
Dave Gills - 2015/10/13 00:28:26 UTC

Sometimes you do a combination of the above.
The wind can be cross/switchy and turbulent.
For all those things...Yes, speed helps.
Bull fucking shit, Dave.
David Stevens - 2015/10/13 21:12:03 UTC

According to those on the ground Jessie was coming in on a long final with plenty of speed when he got turned at about tree level by thermal activity.
According to those on the ground Jesse was coming in on a long final with plenty of speed when he got turned by thermal activity. So we've absolutely ruled out additional speed as a factor which might have resulted in a better outcome.

And dontchya think that if that were anything that we should be discussing in this thread somebody would've brought it up subsequent to David's post?

And he corrected exactly as he was supposed to have - not too much, not too little, JUST RIGHT.
Dave Gills - 2015/10/13 20:41:32 UTC

I'd rather go into the trees than catch a tip.
I totally agree with you. In hindsight the best thing to have done would've been to pick a wide dense patch of forest a safe distance from the strip and put his finely honed spot landing skills to good use. But by the time he was down to 35 feet inside that deadly strip that was no longer an option. Let's face reality here. By the time he'd turned onto final he was totally fucked. Kinda like a black hole's event horizon.

The reality of the situation is that we engage in a sport that has risk but that's part of the attraction. Tell me that whenever we hear about another guy clipping a tree and getting splattered in the primary we're not practically overpowered by an urge to strap our gliders on our racks and head for the hills.

I'll admit that I haven't figured out Hyner.
The last time I was there during the July party, it looked like a whack-fest.

As I said before, I stay away from the place.
I would like to hear what the pros & cons are regarding various approaches.
I expected a more vigorous discussion following the accident.

Dennis Pagen was my wire man last time I was there and recommended the standard Hyner approach.
The slipping 180 into the slot.

There has got to be a better way.
My thinking is a long final.

That's OK, in the span of its entire four and a half decade history hang gliding culture hasn't been able to figure out what a landing is.

ALL dead, light, switchy, turbulent LZs look like - and ARE...

Why I don't paraglide
Tom Emery - 2013/04/17 14:29:12 UTC

Been flying Crestline about a year now. I've seen more bent aluminum than twisted risers. Every time another hang pounds in, Steven, the resident PG master, just rolls his eyes and says something like, "And you guys think hang gliding is safer."
Gil Dodgen - 1995/01

All of this reminds me of a comment Mike Meier made when he was learning to fly sailplanes. He mentioned how easy it was to land a sailplane (with spoilers for glide-path control and wheels), and then said, "If other aircraft were as difficult to land as hang gliders no one would fly them."
...whack-fests.
As I said before, I stay away from the place.
Shouldn't do it for that reason.
I would like to hear what the pros & cons are regarding various approaches.
Do whatever the fuck you feel like. It's an infinitely long runway so you can't overshoot unless you're a total moron. All you need to do is arrive at treetop level with lotsa speed and err on the side of more speed until you're down in ground effect. If you've got a smooth headwind or you're feeling lucky and have some spare control tubes with you go for a standup landing. If you wanna land as safely as possible do exactly what Niki does in the post I was working on when you reappeared which I'll submit before too long.
I expected a more vigorous discussion following the accident.
1. Following the what?

Dennis Pagen was my wire man last time I was there and recommended the standard Hyner approach.
Ask him if he's still recommending the standard aerotow weak link and tell him to go fuck himself for me next time you see him.
The slipping 180 into the slot.
Can't argue with him on that.
There has got to be a better way.
Don't ever attempt a foot landing that isn't a total no brainer. I tried to get that crap game down over a span of 28 years and at the end I realized that it was a total scam and hated and hate myself for having gotten suckered in.

I have to say that landing on the wheels is so much fun it's not funny.
You are depriving yourself of an enormous amount of fun. You're coming in justifiably anxious, worried, scared when you should be experiencing something that's really cool in every sane flavor of aviation.
My thinking is a long final.
Yeah, you can do that - at Hyner and damn near every other primary LZ on the planet. But then you're not practicing for short/restricted field landings. And I DESPISE long finals. They're boring in the primaries and they're extremely dangerous whenever you're playing for keeps.

THIS:

05-2704-c
http://c2.staticflickr.com/2/1525/26167489042_9f5e5af537_o.png

is COOL. It LOOKS dangerous, scary but it's not. It's just FUN - and easy. Work up to it. Push your comfort zone a little each time.

For Hyner specifically...

- Pick a direction based on the ribbons and start a downwind at an appropriate level. If there's a cross, like you've said, run the downwind over the downwind side trees.

- Stay over the trees but close to the edge of the field.

- The lower you get the more you pull in. And you're going downwind so you'll see tons of groundspeed. Wanna be hearing lotsa wind too.

- When you get uncomfortably close to the treetops crank and bank. You'll wang around in a climbing turn and finish your 180 perfectly lined up on the centerline. If you don't - adjust.

- Stay prone on the fuckin' basetube planning to belly in - even if you might decide to go for a foot landing once you've trimmed out in ground effect.

- Nobody ever got hurt by diving from treetop to ground effect level too fast.

- Then you can skim forever.

- Or what I used to do a bit at Hyner... Porpoise back up. Keep pressure back on the bar as you top out to ensure that you don't exprerience a harmless inconvenience stall.

- Back down to the skim... Let the glider decide when it wants to stop flying. If you tell it to do something it doesn't wanna do it has ways of retaliating - even when it's at great cost to itself.

And you can adapt that approach to ANY restricted field.

Currently working on harvesting stills from David's video. Close enough to what I'm describing. Can't go wrong with it.

Short version...

Watch somebody doing an approach and landing that strikes you as super cool and emulate it as much as possible near the edge of your comfort zone.

P.S. Feel free to post this to The Jack Show. He's always looking for good material from other forums.

Do a reverse pattern while swooping a co-owner of the company that built the glider you borrowed for a demo flight. Wheels would have been fun here too.
