OK, a couple posts by me since I can't do a multi copy on iPad...

Yes, AS started with crashworthy cockpits with the -24. I was shortly on scene to a Discus(?) crash due to hitting low wires on final.
Result......Canadian pilot with broken ankles/lower legs that a -24 "may" have prevented. He still flies.
Later AS ships have similar cockpit protection. Likely part of their marketing today.
I believe other mfr's do similar now.

Many peeps frown on SGS sailplanes, they (the mfr) knew about this maybe 50 years ago?
Sigh.......now it's a big thing?

Sorta peeves me off.

Yes, cockpit structure can help lessen injuries, that, is a good thing,
