One small comment from a civvie who has a strong interest in Aviation Safety etc [don't we all ?]
This in one incident that really scares me - it really smacks of a serious lack of appropriate care and attention on the flightdeck. I would expect to read something like this regarding Indonesia or some other part of the world with questionably enforced standards of training and oversight but an Australian Aircraft flying for an Australian Airline with [I presume but could be wrong] Australian pilots ?
The media response from JetStar is media puffery at its finest, secure in the knowledge the proles won't pick up on this one.
To this relatively-uninformed observer the holes in the cheese are lining up more and more frequently and a lost-cost Australian carrier hull loss is inevitable, rather than just possible.
Yet another reason I insist myself and my family fly a full-service carrier but enough now I'm starting to doubt that one also.
