VULCAN AND MARTEL
If my memory serves me right, there was a trial flight where a Vulcan launched a Martel at Llanbedr range against some old ship radiating a signal. This following may be my old memory playing up, but apparently the missile took a liking to the Dublin television transmitter and went on its merry way in that direction. The safety cell decided that war with Ireland was too much to bear at that particular moment and pressed the destruct button.
