From the same thread....
2 years into flying in Australia, after 12 years in the US, I've come to the conclusion it's because they have sub-concious feeling of inferiority. It's almost as if they (the Australians in particular) have to make operating an aircraft as difficult as possible, just to prove they're better at it.
I've come across some of the most mis-placed arrogance, I've ever witnessed in what is a pretty "cocky" profession, from guys who've never flown outside of Australia. Don't get me wrong, I'm proud to be Australian and my heritage but they do a great job of sucking the fun out of what can be a great job.
