Yes the BOI will produce the established facts. However, their report will only form one part of the evidence for the coroner. Other factors will be considered in order to ensure the whole truth is revealed and blame (if there is any) assigned. So I say to Tapper Dad, and all the other families affected by this accident, keep digging - for the truth.
Let us not forget the recent "blue on blue" case, involving a British soldier and two American A10 aircraft. The US BOI, support by Des Browne and MoD cleared the pilots. The coroner, aided by a newspaper and family research and investigation, thought differently. He returned a verdict of "Unlawful killing". Big difference.
So in Churchill's words, the BOI report will not be the end, it will not be the beginning of the end, it will be just the end of the beginning. The rest will most likely by completed by the families involved, and people who are prepared to come forward to help.
