By the way Marc,

The DG 600 in question did have an AoA stall warning device.
Obviously, that didn't help.

"The stall warning system fitted to the glider consisted
of two orifices on either side of the fuselage, one close
to the wing leading edge and one at approximately
mid-chord. The pressure readings from these orifices
are fed into a cockpit mounted variometer. As the
angle of attack of the glider's wing approaches the
stalling angle, the airflow over the wing changes
giving a differential pressure between the forward and
mid-chord orifices. This produces a movement of the
variometer needle, and an audible signal to warn the
pilot of an impending stall."
