I was a relatively short term swimmer in the EK pool but the way I saw it was that people washed their laundry in public precisely *because* everyone knows it will never be seen otherwise. Ask the average punter about Moscow or even Melbourne and I guarantee only those with a decent interest in aviation would know what you mean.
It would take a massive shift in thinking for there to be a just safety culture in that place. The posters in the lifts are a sad joke. It's never going to happen- until they really do get a smoking hole sadly.
The fact that 521 wasn't a massive wakeup call and that things apparently seem to be getting worse IMHO points to that.
I feel for those who will just happen to be there when it happens through no fault of their own. Other airlines have been there and provide the learning examples. If only they were heeded by those with the clout to DO something.
