Admittedly this could be anywhere, so you have to trust me this was over Loch Gorm on Islay. I believe it’s some kind of RAF jet on a training exercise, that’s all I can work out.
Update: It’s a Hawk Trainer, thanks to Chris for the information.
Blink and you’ve missed it. Fighter jets are rather fast, only just managed to catch this one in a picture as it shot over Islay, turning over Machir Bay. This was in October (2011), considering all the Geese and Swans arriving around that time I’m not sure it’s such a good idea to practice flying low over Islay at that time?
Seen from Ardnave, the Hebridean Air Services plane on its way from Islay to Colonsay (and on to Oban). Here it is passing the mouth of Loch Gruinart, Killinallan (not visible) on the right. Paps of Jura on the horizon.
