I remember about 25yrs ago a private owner at Denham who used to preach to me that turning back was a good option, I was an instructor there and was always very sceptical. A few years after I left there I sadly heard he had an engine failure after takeoff tried to turn back in his C172 and spun in and died.
At airfields with no good option in the climb out zone it must be really tempting if it happens, but in 30yrs of flying most of that insutructing in light aircraft I've never considered it or taught it, it just sets the seed for that day if it does happen, you revert to what you have been trained to do so even practicing turm backs is negative training.
My thoughts go out to the family and friends of the Moth pilots.
