An interesting read. A turn around is all well and good for an experienced pilot who knows his aircraft well, however the majority of private pilots are either students in training, where the safest option by far is to land straight ahead and take whats coming, or low hours pilots who do little more than the 12 hours a year to keep their licence.
The issue that isn't discussed in the article is that you would then be landing with a tail wind. So you take off into a nice 10-15kt headwind, the engine goes pop so you turn back and have to somehow get the thing down with 15kts behind you? how many people have trained for this? I've landed in a 7kt tailwind and that was bad enough, I've seen someone attempt to land in a 12kt tailwind, ended up 600 meters into an 800m strip, and just managed a go around at the last second.
If you're very current on type and pretty experienced there's no reason not to attempt this manouver if you think it is the best option at the time, but for the vast majority of people who fly light singles it would either lead to a stall/spin senario, or a duffed up tail wind landing - albeit that saving the aircraft at this point would be your last concern. Really, it depends where you are and what is available off the end of the runway. Most of the strips I have trained from have very suitable landing sites, so turning back would never be a consideration.
