Silverstreak, sir.
Simply because we have no further information from AAIB does not mean that AAIB has no further information.
(i) I incline to the view that AAIB does not leak- it can't see the point of it, it's not a useful exercise from their perspective.
(ii) We do not set the time frame for AAIB reportage - a process which is currently well within their standard pattern. Look at some of the previous excellent postings on this.
(iii) IMHO we need to be patient.
The frustration v trust dichotomy is never an easy one to resolve!
