Hi Andy,
And good to work you on one of the summits I ‘cut’ my feet on as a youth.
Interestingly we had some friends around last night for dinner, and one of the women was into psychic phenomenons. She asked if any of us had any sort of strange experiences? So I related this one to her:
I must have been about 14/15 years of age and the Campsies (the hills to the north of Glasgow that the Meikle Bin resides) as mentioned above were my training ground for map reading and navigating. It was a beautiful winters day with a good covering of snow on the ground and a lovely blue sky with hardly a cloud. Visibility was excellent.
Having spent a short time enjoying the view from the summit of the Meikle Bin I descended to the ‘toll’ road that runs between Lennoxtown and Fintry. Arriving at the road I sat down to enjoy my ‘jelly piece’ and coffee. Casually looking back up to the summit trig (now where I was sitting was maybe about 1Km from the summit and as I mentioned there was excellent visibility and of course as a youth the ‘old’ eyesight was in pretty good shape) I saw this white ‘entity’ - it was like a cloud (but more of a cotton wool consistency) slowly circling the trig point. At that time the OS kept the trigs well maintained with the trig’s white showing well against the blue sky. The entity was twice the height of the trig and slowly rotated around the trig obscuring it as it rotated finally disappearing instantly (there one minute gone the next). The whole incident lasted I think for no more than a minute?
As usual I was on my own so unfortunately nobody could verify my experience. Now as you mentioned Andy about the plane crash, was it some presence that resides on the summit as a result of the crash. Interesting don’t you think?
Wow!, 
I’ve just scared myself to death! I think I have to think seriously about visiting any more of these SOTA ghostly summits?
