Airborne Aircrew makes a very honest point - no-one really knows why the aircraft hit the Mull beyond any doubt whatsoever.
Nevertheless, I consider that comments about the preparation for flight are irrelevant from anyone except RW aircrew intimately familiar with the conduct of such flights. Whether you're a recce puke, fag charioteer, tanker wanquerre, trimmer, kipper mate, mud mover, corgi carrier, shiney, bona mate or whatever (those are banter nicknames, not insults, by the way) - your opinion may be at best naiive and at worst distracting.
Incidentally, bast0n, you may be reassured to know that I have a written undertaking from the next Prime Minister, David Cameron, that he will indeed overturn the findings of Wratten and Day 'unless presented with overwhelming evidence to the contrary'. He is a decent, honest guy and I trust his promise completely.
