Interesting collection of videos ...

The first pilot could have benefitted from Joe Greblo's training to go upright a bit earlier.

The car stopper was impressive. It must be anchored pretty well.

The crew members jumping the arresting cable were quick as cats.

I'm glad the pigeon net was used on pigeons and not Hawks. Let's not give USHPA any ideas. ;)

Safe-Splat solutions may take a hard look into stabilizing the head and neck, not just conventional helmeting. Filling the gap of the neck, bracing the head, and prevent compression of the head into the spine by arresting at the shoulders and hip may arrive to the solution space.

    Skull impacts

    Neck fill

    Brace head linearly to torso

    Prevent compression of head into spine *arrest at shoulders, hip, thigh

Arrest-limit lines without rebound to be based from the lower end of the two queenposts
(uprights; downtubes; sides of control frame; side edges of triangle control frame (TCF) )???

Additionally; 'retractable landing gear' may be the direction this is going. In the specific instance, the cart, or dolly, may be attached semi-permanently, allowing for extending of the feet as the gear in question! As for body protection, the air bags were to be strategically placed to take into account your very real concern for our fragility. Another Time,Terry

Each of those points are chapters in this game. "Retractable" is cousin to deployable. Bob Kuczewski gave high focus in a conversation a day or so ago, on out-of-the-way deployable Safe-Splat for those intending long flights; the "out-of-way" solutions would not be need for those specializing in very short flights where launching and landing are very close in time.

:) :!: Tony Prentice, hang glider pioneer of UK, offers:

When doing low level testing the skis provided a fail safe allowing a belly landing without damage. Some of the slopes used for testing were very shallow and extended glides in ground effect would bleed off speed leaving insufficient for a full flare stand up landing. The skis also allowed a complete novice (see attached photos) to master the landing without too much drama.

In this Safe-Splat project at US Hawks, someone may consider advancing a deployable version of what is seen.

Invited all: to forward arrest lines for Safe-Splat systems. We need to retain flying control authority in any solution. :idea:

Knee cap, patella,
Most of us have two knee cap bones. They usually stick out in front of us. Projections! Shrubs and boulders and kneecaps do not mix well. A dragging HG pilot in splats may aim to prepare to protect knee caps.

Non-catching guard plates that have a bonded inner foam may begin structure higher up the body in order to effect a ski-protection. Just local guard for impact does not take into account the sliding jeopardy. Avoid catchy constructions. What have we?

Fill frontal thigh to a level more frontal than the knee cap and then have plating that continues past the top of the knee. Think smooth without bumps. Consider integration with flight suit. Think fish scales or roofing tab layering as a shin and toe guarding will be next in the slide-hit challenge.

Two distinct branches of attention:
1. Pod solutions.
2. Non-pod solutions. This realm personally has my first attention.

Solutions and forwardings for kneecap in Safe-Splat are invited.
General images where perhaps not one satisfies (in dragging most, if not all seen, have catchy aspects that brings my "no" vote), but might be a source of ideas: http://tinyurl.com/KneeguardsLIFTimages

Hi Joe,

That's funny with the ducks.

You might have something in the patella protector.
