Well I'm glad the pilot is ok, but curious if there is a lesson I should learn here. Given a good distance from anything else hard, this doesn't seem like it should result in an unscheduled disassembly.

If you are thermaling, the glider is not operating anywhere near a structural limit like any max G or speed. Flying an inattentive slow circle makes for the stall and subsequent spin. (Ask me how I know.)

So why not just fly out of the unusual attitude? Was there another glider, or not enough distance to the ground? Or perhaps there was a problem with the recovery?

The NTSB seems to say that a stall spin should result in a broken glider. This doesn't seem right unless there is no other margin.

There have been a number of accidents resulting from spins degrading into high-speed spiral dives. Particularly with some of the long wing birds. Not saying it's unavoidable, but it is something for all of us to keep in mind.

It takes about 8 sec of freefall to reach the glider's VNE of 145 kt (less if the glider's forward speed is converted to the vertical, in which case it may take only 5 sec). To some this may seem like an eternity, to others it happens in a flash. As always, this situation requires the immediate application of the appropriate recovery sequence
