Making an arbitrary turn back in the hope that you land "somewhere near the airfield" to me is not an option either.
Obviously that's entirely your choice.
It was, however, as both I and Beagle have mentioned, an RAF requirement that their QFIs regularly practiced doing so. It was NEVER an arbitrary turn, btw. Perhaps no point in discussing it further, but I would ask: How many times have you actually carried out a practice turnback?
