There is no need to speculate here as there were experienced eye
witnesses to the accident.

The take off was into a quartering headwind from the left. The weak
link broke at an estimated 150' and the pilot initiated a steeply
banked turn to the right. The glider completed approx. ninety degrees
of turn at which time the nose dropped steeply. The glider impacted at
a high rate, nose first at an estimated eighty degrees nose down
angle.

Bill was an active and very generous club member who will be missed.
