One more.. Lamberton...Fe8, nice little pusher too, in August 1916.

"Like the Dh2 the Fe8 was at first involved in several spinning fatalaties. Major Gooden, the Factory test pilot, therefore demonstrated how to bring an Fe8 out of a spin, and therafter the machine became popular."

I interpret that as spins were very much a part of a pilots life in ww1, intentional or not, and that once they learnt how to recover from a spin, well, they recovered...they survived.
