Thanks, I see the planes going over Drogheda to Dublin in a southernly direction, and had thought that was the flight path, it makes sense there is another one but this just seemed so odd, with the time of it as it was really late, the direction the plane was headed in which was not Dublin, and how low it was flying, as usually the planes over us going to Dublin are much higher and closer to the start of the descent rather than the end of it.
Anyway good to know thanks for the info.
