Evidence to the BOI regarding the actual weather at the time of the crash :-
Mr Murchie Lighthouse Keeper and Met Observer: "I would estimate the visibility at this stage to be 15 to 20 metres at the most".
Mr Lamont Lighthouse Keeper and Met Observer: " the visibility, as I drove over the hill from Campbeltown to the Lighthouse, was down to about 10 metres or less".
Mr Brocher: The weather was really bad at this time, there was a lot of mist and fog, visibility was only about 10 to 15 feet."
Mr Gresswell: "The weather conditions en route to the Mull of Kintyre were that of very dense fog."
Mrs Crabtree: " The weather was really bad, we couldn't see the hills on either side of us because of the thick mist."
Finally, Mr Ellacott: " I then heard the sound of a propellor going around for about four or five seconds and then I heard an explosion ....Visibility at that time was only about 9 or 10 feet maximum." "It was difficult to say how far I was from the explosion, but I don't think I could have been any more than 100 yards".
