Possibly the difference between an a -181 and a -161, don't think we need argue over 3 knots. Forget any differences in training standards, I'm an expat pom in any case..
I personally think you're overstating the differences, but I'm happy to agree to disagree. The glider doesn't have to stall either, it requires prompt and positive action from the pilot, as does the powered a/c (my previous post should probably have been worded 'absolutely possible').
Getting back to the main topic I think we're agreed - nose down and look for something soft! If there's any doubt in your mind about making the turnback, you're too low.... And hey, it's another reason to make glide approaches - that way you're familiar with the glide performance
