Safe-Splat might have brought a different result by a master:

A very mild whack, such as this, is still a downer for any pilot. Even though we all can make one, especially on no wind, it is the most embrassing event ever and even more so when it happens on a single surface wing Rolling Eyes
I would rather that a sled ride off the mountain than be filmed in a "whacko" moment!

I think I will start a new rating:

Whack 1… for H1 pilots
Whack 2…for H2 pilots
Whack 3… for H3 pilots
Whack 4…for H4 pilots
Whack 5…for Master pilots

Then a severity whack factor:
1. Mild - soft - easy - nose over- lightly touch
2. Average - nose bonk - nothing hurt on glider or pilot - just pilots ego hurt
3. Hard - whamo - check glider & pilot lucky to not get hurt
4. Bam Wham-a-Lam - down tubes broken -
Pilot took a kicking but still ticking - wing gets damaged.
5. Earthquake… pilot needs medical attention

I. This video it was just a Whack 5.1

Whacks should be measured with some sort of scale much like earthquakes, tornados and hurricanes… Shocked

A joined-wing HG is shown. The hang loop is indicated.
The Safe-Splat skis are in red; they may be widened near the front and then width tapered to smaller toward the rear, as wanted.
The span may be altered; the dihedral of the lower wing may be changed. Want thick airfoils? Have fun!
The above is not tetrahedral, but triangular-prism based.

As we just mentioned Alexander Graham Bell, we note some hang gliding matters in his National Geographic article in Vol. XVIII, No. 1, January, 1907.
We may notice some absence of Safe-Splat, but stay ready to meditate over findings in the article for such.

March 2, 2015, version of a Safe-Splat Joy Frame
with sturdy fore and aft elastics and ski hinge to uprights.
Also: Running-knee control bar or belly-bar control bar.
Extended uprights in TCF provide kingpost opportunity, Wing-mount opportunities, and wing-staying opportunities.
The version may have an empty wing or any positively materialized wing. The uprights my be employed to queenposting duty for having flight lines.
High-tailing may be explored using the upper extensions of the uprights of the TCF.

Enhance the Safe-Splat Joy Farme (SSJF) system just sketched by:
1. The foot assembly below the grip and control bar is to be a female part receiving the upright part to form a tubular shock-absorbing system. Aim to keep the mass in the female lower section. Upon splats, the ski will contact the landing surface and the rate of falling mass of the pilot and wing will be slightly damped. Also, the arrangement will permit exchange of a variety of splat landing feet (various types of skis (various insets of wheels; various insets of ablative braking pad)).

2. The net angle of the upright extensions to the kingposting system will handle wing-attachment opportunities with a variety of positions and heights. Angles will vary depending on the wing of choice. An empty wing has one see no positive wing structure, only the Joy Frame for safe-splat operations. Advancing from the empty wing will bring drag from above, and some negative or positive lift or zero lift. One may choose to have a wing with negative lift. One may choose a wing with neutral lift. One may choose a wing with positive lift. One may design and attach a wing that has a low or high L/D. One may attach to a Safe-Splat Joy Frame a wing that is dominant with positive inflation bladders or ram-air inflation bladders. Or one may design a monoplane with more rigid parts; or a biplane wing set; or a triplane wing set; or a quadruplane assembly. One may have framed flexible-sail wing. One may attach wings to the SSJF via kiting tethers. Or one may mount a set of flags. The wings or flags or kited wings may have messages on their surfaces. One may mount a wing set that is dedicated to forming musical sounds when the apparent wind increases by wing running or flying. One may mount various HAWT or VAWT to the upper regions of the SSJF in order to generate electricity for various loads of choice. One may mount a chair between the two kingposts for giving a ride to a small pet that would joy the circus splatting. Or the two kingposts could join again up there to form one extending flagpole where one mounts a very high flag; run the flag about the ring and stumble safely. Etc.

3. The "join" may be of a variety of solutions. One solution is simple whipping. Another is a specialized heart part that receives four COTS tube or beams of various cross section. Another option is to bolt a left upright to a right upright beam. The uprights may be simple or high-tech (perhaps with various shapes along the upright. The uprights that allow the lower two-part shock-absorbing scheme are necessarily made of parts more than one.

4. The ski meeting the lower end of the upright leg uses a join of a hinge (various options). One option is a hinge that is broad as the ski width where the hinge line helps to stay the left-right attitude of the ski foot. The upright leg part meets the ski at an oblique angle.

[JoeF]

Some focus on the hinge that joins the ski with the female upright part:

HingeFocus001SSJF.png (7.61 KiB) Viewed 5904 times

First blush is a wanting the hinge to be as wide as the ski at the join station;
such would give a firmness wanted at this stage.
Not evident in the sketch is the oblique angle: the female shock absorbing leg part
will be meeting the flat of the ski at an oblique angle.

The sketch is certainly not showing the shock absorbing mechanism. The laconic lines
are only globally suggestive. Before too long, I or others will be showing photographs
of models of various sizes. Testing of parts will be needed.
