"Has that question been fermenting in your mind for the last 30 years!!"
Well............Yes! It just seemed such a strange sight seeing a stream of Vulcans at high level over Glasgow?
At the time I thought it was some sort of Navex using the old 'GOW' which was situated on Eaglesham Moor to the south west of Glasgow, indeed military types over Glasgow seem rare these days, last ones of note (except for C-5's/C-17's etc) about 2 years ago were three Hawks heading south - north, couldn't miss them as the outer port one barrel rolled over and around the other 2 directly over Glasgow
