Bracing for impact on a hang glider
Dissection of one of the most moronic hang gliding instructional videos I've ever seen. Eastern European and thus extra disappointing.Michael Karmazin - 2019/03/29

Safe landing is always the best option for any aircraft, including a hang glider. However, crashes do happen - and if it happens on a hang glider, the pilot should know the course of action to take to reduce the risk of injuries.
Many HG pilots consider bracing as a well-known practice. However plenty of pilots still have no idea of it, which leads to (often preventable) injuries. This video is showing some examples.
Including a hang glider? Since when? The best option for landing a hang glider is a perfectly timed flare onto an old Frisbee in the middle of the LZ to prepare for that inevitable day when one will find one's only landing option to be a narrow dry riverbed with large rocks strewn all over the place in light glassy smooth morning or evening air. Or possibly violently turbulent midafternoon air. Safe hang glider landings are pretty much only done by tandems in which the thrill ride driver and his passenger roll in prone onto Happy Acres putting greens.Safe landing is always the best option for any aircraft, including a hang glider.
Furthermore...
You depict eleven distinct samples whose first appearances are: 0:14 - 0:57 - 1:17 - 1:28 - 2:18 - 2:44 - 3:38 - 4:18 - 5:03 - 5:24 - 6:04
Zero of them are them are with the glider in certified configuration - prone with both hands on the control bar at all times. And that issue is massively relevant in all negative outcomes.
New thought... A glider not equipped with wheels or skids (or floats) adequate for available landing surfaces is not a certified glider 'cause it can't be landed in certified configuration which - as all landings are mandatory - is when it's a near dead certainty that it most needs to be in certified configuration. It also can't be foot launched in certified configuration but we can let that slide most of the time 'cause all launches are optional and we can select circumstances and conditions in which the glider can be reasonably safely foot launched.
We'll break the samples down into the following categories:
- launching - foot - light air - blown:
-- shallow slope: 0:57 - 1:17 - 1:28 - 2:44
-- flat ground foot launch crosswind underpowered towing: 3:38
- mid flight:
-- demo: 2:18
-- elected crashes: 4:18 - 5:03
- landing:
-- approach crash: 5:24
-- surface crash: 0:14
-- controlled: 6:04
So precisely ONE of these eleven flights - 0:14 - is a landing crash.
3:38 gets airborne for pretty precisely half a second 'cause the wind is ninety left cross and his idiot scooter driver makes sure the power is kept at a really safe level and the "flight" is safely terminated with the glider stopped with nose pitched up at about launch attitude. He's on his feet and has stepped across the control bar with the nose still positive. Everything that happens after the glider stops is ground handling and totally irrelevant.
The same way shit does. So we're just rolling dice every time we launch - just like in all other flavors of aviation.However, crashes do happen...
When....and if...
Right. It just HAPPENS on a hang glider. And the pilot who had no fuckin' clue how to keep the crash from happening needs to be a finely tuned and practiced expert on reducing the risk of injuries....it happens on a hang glider, the pilot should know the course of action to take to reduce the risk of injuries.

Weaklinks
So we all gotta fly with Infallible Weak Links and learn how to brace for impact.)Donnell Hewett - 2008/10/14 00:49:34 UTC

But I still believe, "Anything that can go wrong will go wrong." It is only a matter of time.
Good luck with that. I hope we have enough bandwidth to handle all the expressions of gratitude from the pilots who've employed these techniques and walked away from really ugly situations smelling like roses. 22 responses to date so they should start pouring in at any moment now.
I think you're right.Many HG pilots consider bracing as a well-known practice.

Paragliding Collapses
One hundred percent of those have been consequences of arms being braced on control tubes.Jim Rooney - 2011/06/12 13:57:58 UTC
Most common HG injury... spiral fracture of the humerus.

...and shoulders torn apart.
And let's be extra sure not to say anything about preventing crashes....which leads to (often preventable) injuries.
Everyone and his dog knows that bracing for impact is the absolute last thing you wanna do in any game you may happen to be playing. And at no point in this video do we see anyone doing it. On the rare occasions when we see anyone doing anything relevant he's PULLING his body to a side to mitigate a situation. That's the OPPOSITE of bracing. But in real world crashes involving reasonably competent pilots who've gotten into situations they CONTROL the glider to the last possible instant then let go of everything and go limp. This is what we're seeing on ALL crashes in which we can really see the crash - 5:03 being the sole exception.This video is showing some examples.

Major amendment at the end of:
http://www.kitestrings.org/post11798.html#p11798
I'm calling 1:17 - 010-B-11612 totally staged. So for the above ten actual flights, three shallow slope blown launches.
Initial error when I said:
1:17 would've been if there'd been any actual flying involved.Zero of them are them are with the glider in certified configuration...
