At the same time there is talk of a BA flight going around after touchdown in Nice...
What say the populace now?
I would imagine that the populace would say that missed approaches happen for a number of different reasons, many beyond the control of the crew.
Nobody is arguing that a GA of itself necessitates any finger-pointing - go to a large airport like LHR and you will see at least one a day, on average.
So it's all about the circumstances that led to the GA, not just the fact that it happened. Unless you have information on the sequence of events that occurred at Nice, assuming what you have heard is correct, then there's not much point in raising it.
