I am really not sure what an enquiry of up to six months hope to achieve other than boosting the lawyers fees, The AAIB findings are clear. The relatives need closure, there claims in law are without question, and it would seem best that they have closure and financial settlement as soon as possible.
What is it about Britain, endless enquiries led by some retired judge, going on for months and years. A case in point, the Grenfell Tower, very obviously down to building standards/materials yet attempts to blame London Fire Brigade, who did there very best under the circumstances.
