Our friends that had the last flight may done a normal basic training
flight. But, a previous flight might have damaged the glider.
Unfortunately, no one said anything about over stressing the glider and
someone else paid the price.

I think that accident investigators can fairly positively tell the difference
between a structure that has failed from overstressing and one that has failed
from fatigue. The AD says "The preliminary investigation has revealed that the
fracture may have been due to fatigue". So there seems to be little reason to
suspect this accident resulted from prior overstress damage; particularly damage
from a recent flight.
