Afterthought.
Of one thing I am clear and uncompromising. The first job of any aircraft accident report, in any context and under any authority, is to learn lessons and to improve flight safety. Any other function they have is subservient to this requirement and any authority which demotes this primary requirement is doing a disservice to the progression of aviation safety. In this instance the only significant "lessons" revolve around bird control and I can confirm the lessons and subsequent recommendations were applied.
Nothing came from the "lightweight headgear" comment though - rightly so in my opinion.
