Was working in the garden today (Saggart/Citywest area) and heard a large 4 prop going over at altitude,looked up and it seemed to be a Herc, and was followed 5-10 mins later by another one (unless the first one had done a large circuit?), they seemed to be climbing judging by the sound. they flew in a south/southwesterly direction. They seemed too high to have climbed out of Baldonnell and too low to be just passing through so I can only assume they came from Dub. Approx 14:40-14:50 today. Anyone?
