Brian,
Hope you are well. It is snowing lightly here at the moment!
I take your point but Mr Ellacott's evidence is consistant with the evidence given by Mr Murchie (a Met Observer), Mrs Murchie, Mr Lamont (a Met Observer), Mrs Lamont, Mr Brocher, Mr Gresswell, Mr Crabtree and Mrs Crabtree.
All of these either heard or felt the Chinook crash and thus their recollections are specifically linked to the time of the crash. On the other hand Mr Holbrook, from the evidence he gave to the FAI, was manouvering around some fishing boats as the Chinook went past and would not have been aware of the crash until it was broadcast by the media at about 1910 hrs. In addition Mr Holbrook's evidence at the FAI regarding the weather differed significantly from that he gave to the BOI in the immediate aftermath of the crash.
Thus we have witnesses whose evidence covers 5 different locations on the Mull at the time of the crash. Mr Holbrook's evidence is related to events before the aircraft reached the Mull with no significant event associated with his observations AT THAT TIME.
Best Wishes
