Not the first time that I've said this, here on this forum....
How FFF can it take the BFU, what, seven or eight years to put out a report for an over-run ???!!??!
It's not even as though this investigation actually required much digging for missing / destroyed evidence or applied scientific / human behavioural research....Meanwhile, the crew have had this hanging over them for seven or eight years....
Now absolutely convinced that the BFU exists only to counter the myth of world beating German efficiency....
