A fascinating photo of a Hawker Siddley Hawk practice firing at the bombing range to the west of Pembrey Country Park near Kidwelly. These aircraft are often seen from the lookout.
Gwyn who took this photo thought there was something wrong with it until he zoomed and realised he had caught it just as it was firing its canon.
BAE Systems Hawk

And Des of eyeLINEphotography has since sent another two shots taken on the same day. On the one on the right the shell cases can be seen ejecting.
