Making an arbitrary turn back in the hope that you land "somewhere near the airfield" to me is not an option either.
Personally my options would be this, Engine fails, maintain flying speed, pick a landing site within 30°, if there isn't one pick one within 60°, if there isn't one look 90°. If, and only if I had the height I'd think about turning back. If there still isn't one the I'll plough it on top of whatever is going to give me the softest landing, if that's a tree great, if it's someone's rooftop then great.
