have seen this twice in 6 years on easterlies. we try not to stop the outbound once it has commenced its take off roll. if you do this you are asking for trouble - hot breaks, burst tyres, lose the runway! the missed approach for 09R takes the aircraft straight ahead to 3000ft so to avoid the 'piggy back' scenario, an early right turn is initiated. theres a lot of airspace to play with to the south.
