Rossian - one of our blokes took off from Dubai once and immediately realised he was struggling. No question of turning of course so all he could do is climb straight ahead with emergency 101.5 % set, hope for the best and try not to think of the JPTs. He reckoned he was 10 miles out as he passed 500'. In those days Dubai was basically surrounded by sand so luckily there was nothing to hit - I'm not sure how it would pan out these days.
