A lot of large airlines now have powerhouse
PR departments, with a scale of operations that infringe on monopolies with power well beyond just market control. Their sphere of litigious influence not only causes the media to think twice on reporting minor transgressions but also regulatory investigations will be kept hush hush for long periods. Large airlines have the ability to hide investigations and delay them until much after the event, which markedly reduces the negative public perception of the incident. I can think of several ATSB investigations into certain airline incidents that have been behind closed doors due to 'not being in the public interest'.
As for SQ is any more dangerous that any other airline in the region, I think something happened in Bangkok a few years back to a local airline, the Rome incident, Munich incident, Perth incident, Mildura etc etc etc. There was also a foreign airline that comes here often that managed to wheels up a 777 during a go-round, and another scrape its arse through a field after the end of the runway. Nobodies perfect as they say...
