I used to field RAF Police low flying investigation branch queries - who was there at that time type. I was always amazed by the detail that the FJ crews could provide to prove it weren't them.
I also had copy of the report in to a complaint by a friend's father. Again very thorough. The RAF simply cannot afford to ignore any complaints as a PQ would surely follow. Also a modest f^close off payment could backfire should the injury or wrong be much worse.
