As many of you have said,go-arounds (or should that rather be 'goings-around?) are a common occurrence at almost any airport.
Mostly,they're initiated by the flitecrew,for any number of reasons,ranging from percieved windshear,an unstable approach,inability to establish properly or to the crew's satisfaction,another aircraft still being on the active,another acft being too close ahead on finals (wake considerations),etc.
then there are go-arounds due to ATC messups like forgetting to give landing clearance,very late landing clearance etc.equally,there are 'advisory go-arounds' as i like to call them,where ATC suspectsthere might be debris/contamination on the runway and cannot therefore ensureas is their responsability,a perfectly safe runway.
i doubt,however,that the pilots would be under close scrutiny for performing a go-around,after all,we're constantly being trained to consider safety above all else,so if the situation warranted it,they'd have nothing to fear even if they were scrutinized.
Depending on the circumstances,it would rather be the Twr controller who would be under scrutiny.
And finally,i think that anyone who wants to ask about a go-around or any other incident should be welcomed.Its often through such questions that we all as a community of aviators and aviation-lovers get to hear about interesting occurrences.
