Selkirk -
There are a number of low fly areas in Scotland, but because of the relatively large area available to the RAF, actually capturing aircraft low level is much more difficult than in the Welsh low fly area. The area between Selkirk and Moffat is one of the routes flown at low level and there are a number of locations along this route where it is possible to obtain photos. I have visited the region on a number of occasions with limited luck. My captures are shown in the link below.
