Thanks guys - informative stuff. I stand corrected on 'automation' having any impact on frequency of missed approaches.
This one today was almost certainly weather-related. Can't say when the decision was made but I'm pretty sure we were over the airport perimeter fence before the crew initiated thrust and whatever else is needed to go around.
And I've remembered one previously. EK into Dubai - it seems a trainee pilot did not lower the wheels. But that was detected some way out on the approach and was less unsettling than today's roller coaster ride.
