I'm going to make a suggestion, and there's no kind way to say this, but I suggest you put the kettle on, make a pot of coffee and sit down and actually READ the report from start to finish, wild fanciful speculation based on your own theories about what might have happened isn't really helping the flow of the debate here. IMHO.
Thanks, BangOrWest. I stand suitably chastised and have deleted the incorrect and wildly speculative part of my post.
I note that you have so far contributed three posts to this very long thread and so I look forward to reading more of your useful and informative contributions.
