JP,
There is a large difference between being unable to understand what happened and going on to accuse the crew of gross negligence.
There are a number of scenarios, which COULD have resulted in the accident, all of them speculation, but equally as valid in the absence of solid evidence. As the BOI stated.
Quote from your last post: "Is there any more to say?"
Your opinion is in line with that of the MOD. So why are you still eager to make your point that the pilots were entirely to blame?
IMHO, there was almost certainly negligence further up the chain. That particular aircraft, or any other Mk2, should NOT have been flying that sortie, or any other at the time. The pilots, although they possibly made mistakes of their own, paid the ultimate price for those management chain errors. They were then spitefully castigated by the management that they had perhaps been perceived to have "let down". Disgraceful stuff.
