Big frank I don't think any of us can give you the pointers towards the documentation that your looking for.
One of the reasons why the investigation is taking so long is the paper trail is more than likely extremely messy.
And everyone will be arse covering as well.
My info is the same as kroack's but its all come from contacts in the industry.
There is also a heap of other stuff which has rumoured to have gone on that none of us can comment on publically because we don't have any proof.
The report is going to be a humdinger of a report and I wouldn't be suprised if it going to be another year before its out. The technicalities of the accident will be realively simple. The rest of it is going to be extremely interesting with the potential of being extremely embaressing for NAA's.
The other thing as well is that there will be several legal cases as soon as its released which makes things even more complicated.
