John Purdey, WOrker,
JP says "Yes, brief because we have been over this ground too often before".
I hope that you will agree that we are on new ground as we wait for you to tell us what the crew could see, and what they could'nt see at the point at which you are convinced beyond any doubt that they should have turned away or climbed.
Please note that the weather information referred to 10 Km visibility in patches. Except for the top of the Mull itself are you certain that they were not in one of these patches at the time?
Holbrook's evidence suggests that they might have been.
