BTW, if all else fails and you are unable to physically get out of you
cockpit after a collision, just jettison the canopy, undo the straps,
lean forward and pull your D-ring. *You WILL leave the cockpit. *It
WILL hurt. *You MAY survive. *Beats the alternative, though!

I know a glider pilot that did this (pull the ripcord while seated in
the sailplane), the pilot chute deployed and she was extracted from
the cockpit OK.

I knew another pilot that tried this, the chute deployed right into
the tail feathers! A tumbling mass of glider, nylon and pilot
descended back to earth.

We need something more reliable with predictable results.
