I have to smile at all these musings about safety cockpits because it
will have virtually no effect on the injury/death rate in soaring. Even
if every new glider had a "safety" cockpit there would be no
significant increase in the percentage of such cockpits for decades to
come. Gliders, as well as other aircraft, will be, and are, kept in
service until it is overwhelmingly uneconomical to do so. And spare me
the "well we have to start somewhere" comment. Personally, I am not
going to spend an extra $100K to replace my current motorglider with a
"safer" one.

That last fatal accident I posted shows you where you need to spend
your effort: influencing the judgement of pilots. This is not an
impossible task; the GA accident rate has been declining even with an
ageing fleet.
