Many flight manuals of newer gliders say that a spin will turn

Spin and spiral dive recovery are, of course, quite different.

Please note this probably has NOTHING to do with Tim's accident:
Experienced pilots have become confused and thought they were
in a spin when in fact they were in a spiral dive.
IIRC a prominent example was the crash of an Eta during
a spin test...

Quick:
- how do you tell the difference?
- recovery technique?

Hope that helps,
