As a local, I'm not at all convinced that this is at Dublin. As a photographer I don't know how you could get a shot at that angle and also the fencing in the background is the wrong type. Furthermore BA 747s have only appeared here on a handful of occasions and it is also a long time since BA A320s were even occasional visitors. I'm inclined to believe it is at Gatwick (runway 08 end) or maybe Manchester. If you are sufficiently interested you could of course e-mail the photographer via the link from the a. net photo.
