And thus shows one of the major problems with the CFS. We just can't stand to evaluate our actions when things go wrong. We're more than happy to stand back and and offer our condolences (as we should) but there is a lesson to be learned from most of these 'accidents' so that they can be avoided in the future.
We need to be open to learn from our mistakes as a service. It's pretty obvious that in this case, as with Mt. Bryan and Murray Bridge that someone cocked up in a major way. Once we work out what has occurred people need to be made aware so that we can learn from this and use this as an example of what can happen when people aren't paying attention, suffer tunnel vision or whatever else may have caused the prang.
Bring on PSTP "Operate and Maintain Common Sense"!
Of course we must learn from the mistakes made. And yes, someone, obviously made a mistake.
However, the actual cause of this crash, and what mistakes were made, are, at least on this forum currently, just speculation. We need to be careful of making assumptions about what happened, based on small snippets of information gained from the media.
