Despite the grievance that you must feel, 9 months is not a long time for a BOI. It is just not that simple. The BoI for the squirrel crash at Shawbury hasn't reported yet after almost 5 months. And that [I]only[I] had one fatal and 3 injured. It happened on a military airfield in the UK, not in a hostile country thousands of miles away. They had access to the wreckage without the danger of being attacked by the Taliban.
I am sorry for your loss, but you cannot prejudge the BoI and NOR SHOULD THE BBC. I will watch the programme, but going by recent BBC journalistic standards I will not be surprised if it is full of inaccuracies and rumour.
