Hey Hey Sam! Thanks for the lead and idea direction. http://youtu.be/JJQ4SB5v7YU "Just have a good landing!" ... narrator. The keel stinger as a flexing device and perhaps landing shock absorber may have been explored carefully; I do not have references yet. http://en.wikipedia.org/wiki/Shock_absorber But the patents have special parachute-landing boots that are for taking up landing shocks, etc. The idea of high flare and drop into tripodal shock-aborbing legs (keel could be one leg) might be explored for niche HG purposes. I will keep a lookout for such Safe-Splat devices. Thanks, Sam,
