Then once again I am indebted for your authoritative advice, SiClick. To be honest the arrangements made for Military Accident Investigation whether they be done in Service or outside, by the AAIB, the MAAIB or a Tri-Service Unit is all the same as far as I am concerned. The important thing is that they be independent, professional and authoritative. It is my contention that in the main that cannot be said of the present arrangements, particularly the RAF ones.
