Strong prevailing winds in N.I. mean most runways are likely to point the same way.
EGAA has Nutts corner and Langford Lodge in close proximity with similar runway alignment. At least two aircraft have landed at Langford by mistake, one of which I seem to remember was a DC9 which turned around and took off again! The other was an HS748.
I myself saw another 748 lining up nicely to land at Nutts Corner and had to intervene, it was a fairly regular event to have to verify to pilots on a VOR approach to 07 that EGAA was the next one along from EGAL.
Hazards such as those should be well known to the Tower Controller, surely he should be on the lookout especially when crews unfamiliar with the area are making an approach. I'm not saying it's his fault, but he should be one more factor that should prevent that happening. I think EGAE only have about 12 scheduled movements a day so I think they can afford the time to look out of the window.
