I saw a few launches from Aberporth when working at Western radar, I was fascinated by all the twitching movements made by the missile on the launcher prior to blast off,these were Swiss owned missiles being launched against Jindivik towed targets.
We could not see the Royal Navy launch site which was below the cliffs and I was very cheesed off to miss the time they shot down the Meteor drone just offshore as part of a sales push to sell ship based missiles to other navies. The Meteor cartwheeled into the sea in a ball of flames.
