Vestas Sailrocket 2
breaks world sailing record on November 17, 2012. [ story is unfolding: http://aerotrope-engineers.com/ ]

The following pre-Nov-2012 record video has some comments that apply to Safe-Splat designing for the HG direction:

=================================

Instead of head first, consider the transition to feet first with heel and butt skids, etc. Protect the spine.

=================================
Braking, not breaking.
Explore all the ways humans have learned to stop motion.

I wonder if they also make tricycles built for two?

[JoeF]

Bill, ... Let's hope the tandem trike of the hang land-flyer comes out soon! Good idea. Best cookie is the shared one!

Perhaps this has a rub into the Safe-Splat design arena:

What comes to mind at the moment:
1. Attain slip.
2. Build in parallelogrammatic reduction during impact.
3. Get into feet first postion.
4. Have back plate that spreads pressure to much of torso.
5. Have anti-whip-lash holding of head-neck-spine unity.
6. Following the splat, slip, slide, then gain braking authority by some means. Perhaps deliberate action could let slow return of the collapsed parallelogram structure with resultant soil gauging.

Air bag, check!
drogue chute, check!
anchor W/bungee cord, check!
seat belt, check!
Life Alert necklace, check!
cyanide capsule, check!
CLEAR!!

[JoeF]

Good checks, Bill !
Those have important matter in them to be explored.
...
Not ready to checkout yet, though.
The Flizz may have something for Safe-Splat HG or WR:

In March-April issue of Ryan Reporter, there was a photo of a hang glider carrying a large payload hanging beneath the flexible wing. That payload seems to feature a specialized Safe-Splat device.


The Ryan Aeronautical corporation had for years very very many hang glider dealings: art, tiny models, scale models, RC models, wind tunnel test models, manned vehicles, unmanned vehicles, tethered gliders, etc. When powered versions of the powered models or manned vehicles were power off: hang glider mode. The shown glider featuring the special Safe-Splat device is something I'd like to know more about. What was the structure of that apparent Safe-Splat broad-skid device? There may be more information in the archives of Ryan Aeronautical, perhaps held by the San Diego Air and Space Museum.
The actual date of the photograph event is not yet known to me. But the date had to have been before the March 1962 publication date!!

Just a comment:
Date in 1961 or early 1962 of this photo, not sure yet: The wing, that seems to be the template for the standard Rogallo hang glider, was here shown being tested in a wind tunnel:

"recently" is indeterminate; actual date of the "manned" paraglider hang glider drop would be interesting for the record.
Safe-Splat by using a dummy
More notes in the Mar-April 1962 issue of Ryan Reporter:
"Manned" Flex Wing drops recently
proved a new application of
Ryan's versatile Flex Wing. A halfscale
model human-figure dummy
using a Flex Wing paraglider system
successfully completed preliminary
drops from 2,000 foot altitudes at
Brown Field, San Diego. Demonstrations
were conducted as part of a Ryan
proposal to the Army Transportation
and Research Command to design a
paraglider system and build full scale
Flex Wings and instrumented dummies
for an experimental drop program.

The Flex Wing was being explored for drone. An early 1962 or in 1961 photo from a Flex Bee:
