Flight Paths Carmarthenshire, 13 April 2010 at 06:34 hours. Carreg Cennen Castle sits on a spectacular crag of rock in a very quiet area of Carmarthenshire. However, I was struck whilst composing the photograph that there was no escaping modern day technology as evidenced by the jets flying overhead. About a week later, it would have been different as a volcanic ash cloud from Iceland grounded all planes for a couple of days. Camera details: EF28-135mm f/3.5-5.6 IS USM, 1/5 sec at f / 22
