G'Day Breeze,
What was your question?
And you may wish to consider that if you are a witness providing some 'official input' to ATSB into the enquiry, you may wish to retain your 'uncontaminated' recall of your interpretations and simply keep what you already have, fresh in your mind, as you may/may not - get 'sidetracked' here by some answers which may/may not be 'correct'........
Not all respondents are experts, IMHO........
Best Regards
